Objectives: To evaluate the associations of hand grip strength (HGS) with body composition, functional capacity, muscle quality, and inflammatory markers in people receiving maintenance hemodialysis.

Methods: This is a cross-sectional study in people receiving maintenance hemodialysis. HGS was measured by hydraulic dynamometer on the upper limb without fistula. Participants were stratified into low or adequate HGS, based on population-specific cutoff points. Body composition was assessed by dual-energy X-ray absorptiometry, and functional capacity by the Short Physical Performance Battery and timed up-and-go tests. In addition, serum creatinine, interleukin-6 (IL-6), IL-10, tumor necrosis factor-α, and ultra-sensitive C-reactive protein (us-CRP) were measured before the dialysis session.

Results: A total of 67 participants (41.8% women, 58.2% male; ages 54.1 ± 11.7 y) were included. Those with low HGS had worse functional capacity than those with adequate HGS (timed up-and-go test, 10.7 ± 1.0 versus 8.5 ± 0.8 sec, respectively; P < 0.001). IL-6 and us-CRP were higher in those with low HGS than their counterparts (IL-6: 2.7 ± 0.3 versus 1.9 pg/mL, P = 0.03; us-CRP: 14.8 ± 3.0 versus 4.7 ± 1.9 mg/L, P = 0.03). Multiple linear regression analysis showed that appendicular lean mass, us-CRP, age, sex, and seven-point subjective global assessment score were associated with HGS.

Conclusions: Participants with low HGS showed higher inflammation and lower functional capacity. In addition to muscle mass, inflammation and nutritional status also affect HGS..

Antioxidant and anti-inflammatory response to curcumin supplementation in hemodialysis patients: A randomized, double-blind, placebo-controlled clinical trial.

Clin Nutr ESPEN 2021 08 24;44:136-142. Epub 2021 Jun 24.

Faculty of Nutrition, Federal University of Goias, Goiânia, GO, Brazil.

Background And Objectives: Hemodialysis (HD) patients are vulnerable to malnutrition and cardiovascular complications due to many factors, including oxidative stress and inflammation. Curcumin supplementation is associated with attenuation of proinflammatory cytokines and increased activity of antioxidant enzymes, but its effects in HD patients are unknown. This study aimed to evaluate the effect of curcumin supplementation on oxidative stress and inflammation in HD patients.

Methods: This randomized, double-blind, placebo-controlled trial enrolled 43 HD patients and divided them into two groups: supplemented with curcumin (1 g/day) or placebo (corn starch) for 12 weeks. Demographic information and blood samples were taken at the start and the end of the study to determine serum malondialdehyde (MDA) concentrations, antioxidant enzyme activity, and high-sensitivity C-reactive protein (hs-CRP).

Results: The curcumin group showed a significant increase in catalase activity [Δ = 1.13 ± 2.87 versus Δ = -1.08 ± 2.68; p = 0.048] and preserved glutathione peroxidase activity [Δ = -4.23 ± 11.50 versus Δ = -14.44 ± 13.96; p < 0.01] compared with the placebo group. However, no significant changes were found in MDA concentrations, glutathione reductase activity, and hs-CRP concentrations after the intervention.

Conclusion: Curcumin supplementation for 12 weeks had potential effects on antioxidant response, but it was not enough to reduce oxidative stress markers and inflammation in HD patients. This trial was registered at EnsaiosClínicos.gov.br under registration number RBR-2t5zpd.

Bone Mineral Density in Severely Obese Women: Health Risk and Health Protective Risk Factors in Three Different Bone Sites.

Int J Environ Res Public Health 2020 09 25;17(19). Epub 2020 Sep 25.

Postgraduate Program in Health Sciences, Faculty of Medicine, Federal University of Goias, Goiânia 74605-220, Goiás, Brazil.

Factors associated with bone mineral density (BMD) are poorly known in severely obese individuals i.e., a body mass index (BMI) > 35 kg/m. The objectives of this study were to describe the bone health profile of severely obese Brazilian women, to identify the health risk and health protective factors for BMD in this group and to assess whether these factors vary according to three different bone sites. BMD was assessed using dual-energy X-ray absorptiometry (DXA). This study analyzed baseline data from 104 women who had an average BMI of 43.7 ± 4.5 kg/m and presented the following BMD status: 1.283 ± 0.094 g/cm for total body, 1.062 ± 0.159 g/cm for vertebral column and 1.195 ± 0.134 g/cm for hip. They took part in the "Effect of nutritional intervention and olive oil in severe obesity" randomized clinical trial (DieTBra Trial). The risk factors negatively associated with lower BMD were age ≥50 years for the three bone sites i.e., total body, vertebral column and hip. Smoking for total body BMD ( = 0.045); BMI ≥ 50kg/m for vertebral column and hip; menopause for hip; high C-reactive protein (CRP) levels ( = 0.049), insufficient zinc ( = 0.010) and previous fracture for vertebral column ( = 0.007). The protective factors positively associated with BMD were physical activity (≥150 min/week ( = 0.001)) for hip; type 2 diabetes mellitus (DM2) ( < 0.0001) total body and adequate vitamin D levels from food consumption ( = 0.039) for vertebral column. A BMI ≥ 50 kg/m was a risk factor for lower BMD. The findings showed that protective and risk factors varied by bone site. The original study is registered with ClinicalTrials.gov. (protocol number: NCT02463435).

Transcultural adaptation of the Thirst Distress Scale (TDS) into Brazilian Portuguese and an analysis of the psychometric properties of the scale for patients on hemodialysis.

J Bras Nefrol 2020 Mar;42(2):153-162

Universidade Federal de Goiás, Faculdade de Nutrição, Programa de Pós-Graduação em Nutrição e Saúde, Goiânia, GO, Brasil.

Objective: To produce a transcultural adaptation of the Thirst Distress Scale (TDS) into Brazilian Portuguese and analyze the scale's psychometric properties for patients on hemodialysis (HD).

Methods: The original scale was translated, back translated, and discussed with psychometric assessment experts. The final version was tested with 126 patients on HD and retested with 70 individuals from the original patient population. Cronbach's alpha was used to measure the scale's internal consistency. Reliability of thirst intensity evaluated via the visual analogue scale (VAS) was tested with Kappa statistic and the Bland-Altman plot. Reproducibility was assessed based on the intraclass correlation coefficient (ICC).

Results: The wording of three items and the verb tenses of six had to be adjusted in the final version of the Brazilian Portuguese TDS. Comprehension of the scale by patients on HD was good, the scale's internal consistency was satisfactory (0.84; p<0.001), agreement with a visual analogue scale (VAS) was moderate (kappa=0.44; p<0.001), and reproducibility neared perfection (ICC=0.87; p<0.001).

Conclusion: Our results showed that the Brazilian Portuguese version of the scale might be used reliably. The Brazilian Portuguese version of the TDS is a practical, affordable, accessible and well-accepted tool that has a lot to offer for the management of patients with HD.

Effect of Extra Virgin Olive Oil and Traditional Brazilian Diet on the Bone Health Parameters of Severely Obese Adults: A Randomized Controlled Trial.

Nutrients 2020 Feb 4;12(2). Epub 2020 Feb 4.

The Postgraduate Program in Health Sciences, Faculty of Medicine, Federal University of Goiás, Goiânia, 74605-220 Goiás, Brazil.

Dietary interventions can stabilize and/or reverse bone mass loss. However, there are no reports on its effects on bone mineral density (BMD) in severely obese people, despite the vulnerability of this group to bone loss. We examine the effect of extra virgin olive oil supplementation and the traditional Brazilian diet (DieTBra) on BMD and levels of calcium, vitamin D, and parathyroid hormone (PTH) in severely obese adults. A randomized controlled trial followed-up with severely obese adults ( = 111, with mean body mass index 43.6 kg/m ± 4.5 kg/m) for 12 weeks. Study participants received either olive oil (52 mL/day), DieTBra, or olive oil + DieTBra (52 mL/day + DieTBra). BMD was assessed by total spine and hip dual-energy X-ray absorptiometry. After interventions, BMD means for total spine ( = 0.016) and total hip ( = 0.029) were higher in the DieTBra group than in the olive oil + DieTBra group. Final mean calcium levels were higher in the olive oil group compared to the olive oil + DieTBra group ( = 0.026). Findings suggest that DieTBra and extra virgin olive oil have positive effects on bone health in severely obese adults. The major study was registered at ClinicalTrials.gov (NCT02463435).

Intradialytic Resistance Training Improves Functional Capacity and Lean Mass Gain in Individuals on Hemodialysis: A Randomized Pilot Trial.

Arch Phys Med Rehabil 2019 11 3;100(11):2151-2158. Epub 2019 Jul 3.

Clinic Nutrition and Sports Research Laboratory, Faculty of Nutrition, Federal University of Goias, Goias, Brazil.

Objective: To compare the effects of high vs moderate loads of intradialytic resistance training (RT) on body composition, sarcopenia prevalence, functional capacity, inflammatory markers, and quality of life (QoL) in individuals on hemodialysis.

Design: A pilot randomized clinical trial.

Setting: Two hemodialysis centers.

Participants: Individuals on hemodialysis (N=80; 51% men, aged 30-75y) in treatment for at least 3 months, adequately dialyzed (Kt/V≥1.2, where K is dialyzer clearance in mL/min, t is time, and V is volume of water) with vascular access via arteriovenous fistula.

Interventions: The 12 weeks of intradialytic RT was performed 3 times per week. The training groups were: high-load intradialytic group (HLG, 8-10 repetitions), moderate-load intradialytic group (MLG, 16-18 repetitions), and control group (CG, stretching exercise). The total training volume was equalized among training groups.

Main Outcome Measures: Lean leg mass was assessed by a dual-energy x-ray absorptiometry; functional capacity was assessed by Short Physical Performance Battery and Timed Up and Go test; and QoL was assessed by Kidney Disease QoL Instrument, inflammatory markers, and sarcopenia.

Results: After the training period, the HLG increased lean leg mass compared with the CG. The HLG also displayed improvements in the pain and physical function domains. The skeletal muscle index and functional capacity increased in both RT protocols. The prevalence of sarcopenia was reduced 14.3% and 25% in the MLG and HLG, respectively, while there was an increase of 10% in the CG. No differences were observed in cytokines after intervention.

Conclusions: High-load intradialytic RT was associated with gains in lean leg mass and QoL while functional capacity, appendicular muscle mass, and sarcopenia status were improved regardless of the RT load.

Is waist-to-height ratio the best predictive indicator of hypertension incidence? A cohort study.

BMC Public Health 2018 02 26;18(1):281. Epub 2018 Feb 26.

Hypertension League, Federal University of Goiás, Avenida Primeira Avenida, s/n, Setor Leste Universitário, Goiânia, Goiás, 74605-020, Brazil.

Background: The best anthropometric indicator to verify the association between obesity and hypertension (HTN) has not been established. We conducted this study to evaluate and compare the discriminatory power of waist-to-height ratio (WHtR) in relation to body mass index (BMI) and waist circumference (WC) in predicting HTN after 13 years of follow-up.

Methods: This study was an observational prospective cohort study performed in the city of Firminópolis, in Brazilian's midwest. The cohort baseline (phase 1) was initiated in 2002 with the evaluation of a representative sample of the normotensive population (≥ 18 years of age). The incidence of HTN was evaluated as the outcome (phase 2). Sociodemographic, dietary and lifestyle variables were used to adjust proportional hazards models and evaluate risk of HTN according to anthropometric indices. The areas under the receiver operating characteristic (ROC) curves were used to compare the predictive capacity of these indices. The best HTN predictor cut-offs were obtained based on sensitivity and specificity.

Results: A total of 471 patients with a mean age of 38.9 ± 12.3 years were included in phase 1. The mean follow-up was 13.2 years, and 207 subjects developed HTN. BMI, WC and WHtR were associated with risk of HTN incidence and had similar power in predicting the disease. However, the associations were only significant for women. The cut-off points with a better HTN predictive capacity were in agreement with current recommendations, except for the WC in men.

Conclusions: The results suggest that both overall obesity (BMI) and central obesity (WC and WHtR) anthropometric indicators can be used in this population to evaluate the risk of developing hypertension.

Predictors of overweight/obesity in a Brazilian cohort after 13 years of follow-up.

Nutr J 2018 01 15;17(1):10. Epub 2018 Jan 15.

Hypertension League, Federal University of Goias (UFG), Goiania, GO, Brazil.

Background: Obesity is a chronic complex disease with an increasing prevalence around the world. Prospective studies in adult cohorts are needed to provide information about predictors of new-onset overweight/obesity on population-based levels. The aim of this study was to identify factors associated with the risk of an adult individual become overweight/obese after 13 years of follow-up.

Methods: Second phase of an observational population-based prospective cohort study in a small town in the Midwest region of Brazil. A representative sample of the adult population (≥18 years) was assessed in 2002 (phase 1). Anthropometric, sociodemographic, dietary intake and lifestyle data were collected. After 13 years of follow-up (2015), the same variables were re-evaluated (phase 2). New-onset overweight/obesity was the outcome variable.

Results: A total of 685 subjects were included with a mean age in phase 1 of 42.7 ± 13.8 years and 56.1 ± 13.8 years in phase 2, the mean follow-up time was 13.2 years and female sex counted for 66.3% of the sample. Total weight gain was 5.9 ± 10.2 Kg, body mass index increased 2.6 ± 3.8 Kg/m and waist circumference (WC) values increased 8.0 ± 10.5 cm. The prevalence of overweight/obesity went from 49.1% in phase 1 to 69.8% in phase 2 (p < 0.001). The factors associated with a decreased risk of new-onset overweight/obesity were ages between 50 and 64 (RR 0.40; CI 0.24-0.67 - p = 0.001) and ≥65 years (RR 0.15; CI 0.06-0.35 - p < 0.001), being part of the second quartile of fat consumption (RR 0.59; CI 0.35-0.97 - p = 0.041), no alcohol consumption (RR 0.59; CI 0.37-0.93 - p = 0.024) and smoking (RR 0.58; CI 0.39-0.86 - p = 0,007) in phase 1.

Conclusions: We identified in thirteen years of follow-up that older ages, a moderate fat consumption compared to low consumption, no alcohol consumption and smoking habit were related to a decreased risk of new-onset overweight/obesity. Obesity prevention actions must focus on subjects at younger ages and include policies to reduce alcohol consumption.

Overweight and associated factors in adolescents from a brazilian capital.

Rev Bras Epidemiol 2017 Apr-Jun;20(2):260-273

Liga de Hipertensão Arterial, Hospital das Clínicas, Universidade Federal de Goiás - Goiânia (GO), Brasil.

Objective:: To evaluate the prevalence of overweight in adolescents and its associated factors.

Methods:: A cross-sectional study in public and private schools in Goiania, Brazil. Socioeconomic status, family history of obesity, lifestyle, blood pressure and Body Mass Index were studied in a sample of 1,169 Brazilian youth aged 12 - 18 years, who attended public and private schools. Data were obtained from a questionnaire and anthropometric measurements previously tested in a pilot study. Poisson regression was used to estimate the prevalence of overweight, prevalence ratios and associations with the other factors.

Results:: The prevalence of overweight was 21.2%, with a significant difference between boys and girls (26.3 and 16.8% respectively). Regression analysis showed that maternal obesity was associated with a higher prevalence of overweight in boys (PR = 1.86; p = 0.004), and boys aged 15 - 18 years had a lower prevalence of overweight than boys aged 12 - 14 years (PR = 0.70; p = 0.021). Among the girls, the presence of obese parents was associated with higher prevalence of overweight (PR = 2.42; p < 0.001), and the girls from a C class socioeconomic position were negatively associated with overweight (PR = 0.67; p = 0.035).

Conclusions:: Overweight in adolescence is associated with gender, obesity family history, and socioeconomic position. These data should be considered when planning intervention programs.

Sedentary lifestyle and its associated factors among adolescents from public and private schools of a Brazilian state capital.

BMC Public Health 2016 11 21;16(1):1177. Epub 2016 Nov 21.

Hypertension League, Federal University of Goias, Goiania, Brazil.

Background: Adolescence is a transition stage between childhood and adulthood and is an important phase for the acquisition of future lifestyles, including the practice of physical activity (PA). The prevalence of sedentary lifestyle in adolescents is often high, creating the need for studies addressing the practice of PA and its associated factors for a better understanding of the phenomenon and possible interventions that would encourage positive changes.

Methods: Cross-sectional study of a representative sample of students aged 14-18 years enrolled in both public and private schools of a large Brazilian city to determine the level of physical activity (PA) and its associated factors. Sedentary lifestyle was measured by applying the International Physical Activity Questionnaire. The independent variables were gender, age, race, tobacco use and alcohol consumption in the past 30 days, socioeconomic status, body mass index, waist circumference and blood pressure. The crude prevalence ratio was used as a measure of association and was estimated from a Poisson regression.

Results: The sample consisted of 862 adolescents with a mean age of 15.4 ± 1.1 years. Females were predominant (52.8%), and the age between 14 and 15 years was the most frequent (52.2%). The majority of the group reported themselves as Caucasians (51.2%), belonging to socioeconomic class C (52.5%) and were attending to public schools (69.1%). The prevalence of sedentary lifestyle was 66.8% (95% confidence interval [CI]: 63.5-69.9), where values of 65.4% and 69.9% were observed among students from public and private schools, respectively (p = 0.196). Sedentary lifestyle was more frequent in females (78.0% vs 54.3%; p < 0.001). The factor directly associated with sedentary lifestyle was female gender both in public and private schools and the only independent variable related to sedentarism was also female gender.

Conclusion: The prevalence of sedentary lifestyle was extremely high in the population of adolescents studied both in public and private schools. Female sex was directly associated with sedentary lifestyle.

Is energy intake underreported in hemodialysis patients?

J Bras Nefrol 2015 Jul-Sep;37(3):359-66

Hospital de Doenças Tropicais Dr. Anuar Auad., BR.

Introduction: Underreporting of energy intake is not much studied in hemodialysis population.

Objective: To evaluate the underreporting of energy intake and associated factors in hemodialysis patients.

Methods: A cross-sectional study, with 344 patients stable adults, of ten hemodialysis centers in Goiânia-GO. Energy intake was assessed by six 24-hour dietary recalls and basal metabolic rate (BMR) was estimated using the Harris Benedict equation. It was considered as underreporting when the ratio between the average energy intake and basal metabolic rate was lower than1.27. For analysis of factors associated with underreporting, the Poisson regression with robust variance estimation was applied.

Results: The prevalence of underreporting was 65.7%, being more significant in individuals who are overweight and in the non dialysis days. The result of the multivariate analysis identified four factors independently associated with the underreporting: being a female (PR = 1.27, CI = 1.10 to 1.46), body mass index ≥ 25 kg/m2 (PR = 1.29, CI = 1.12 to 1.48), three meals or lower/day (PR = 1.31, CI = 1.14 to 1.51) and hemodialysis length lower than 5 years (PR = 1.19CI = 1.01 to 1.40).

Conclusion: The population showed a high prevalence of underreporting of energy intake. Being a female, presenting overweight, lower number of meals/day and lower length time on hemodialysis were factors associated with underreporting.

Nutritional status and interdialytic weight gain of chronic hemodialysis patients.

J Bras Nefrol 2015 Jul-Sep;37(3):306-14

Universidade Federal de Goiás, BR.

Introduction: The nutritional status (NS) of patients on hemodialysis (HD) is a major concern and challenge. Malnutrition is common in these patients and is related to poorer clinical outcomes.

Objectives: To assess the association between the NS and the interdialytic weight gain (IDWG) of patients with chronic kidney disease (CKD) on HD.

Methods: Cross-sectional study with 322 patients older than 18 years. The NS was assessed by body mass index (BMI), percentage body fat estimated by the sum of four skinfolds (triceps, biceps, subscapular and supra iliac), lean body mass (LBM), serum creatinine and albumin and rate of nitrogen appearance (PNA). The IDWG was evaluated from the sum of the weight difference of 12 hemodialysis sessions (IDWGm).

Results: Considering the sample into quartiles IDWGm, it was found that BMI, LBM, serum creatinine ( p < 0.001) and PNA ( p = 0.011) were directly correlated. There was no association between IDWGm and serum albumin. Using multivariate analysis, it was found that the prevalence of patients with BMI suitability and serum creatinine were significantly higher for patients in the bottom quartile with respect to the first IDWGm.

Conclusion: The NS is positively associated with IDWG. The results point to the need for individualized assessment of IDWG and cautious in order not to generalize a recommendation that does not meet the expectations of maintaining and promoting the nutritional status of these patients.

Dental pain and associated factors in 2 to 4-year-old children in Goiânia.

Rev Bras Epidemiol 2015 Jul-Sep;18(3):630-41. Epub 2015 Sep 1.

School of Dentistry, Universidade Federal de Goiás, Goiânia, GO, Brazil.

Objective: To investigate the prevalence of dental pain and associated factors in 2-4-year-old children in Goiânia (GO).

Methods: Cross-sectional study using home interviews with parents or guardians and anthropometric measures. The sample consisted of 385 children from 2 to 4 years old. The variables analyzed were: dental pain sometime in their lives, and demographic, socioeconomic and health-related factors (health condition, diet, nutritional status and behavior). Bivariate analysis and logistic regression were performed, based on a hierarchical model for risk assessment, considering the sample weights.

Results: Dental pain prevalence was 9.9% (95%CI 7.4 - 13.1). After adjustment for other variables, children whose mothers had low education level and those who regularly consumed artificial powder juice containing sugar were more likely to have dental pain (OR = 3.03 and 2.15, respectively).

Conclusion: It was concluded that one in ten children had dental pain, and the prevalence was associated with low education level of the mother and the regular consumption of artificial powder juice.

Vitamin A status and associated factors in infants attending at Primary Health Care in Goiânia, Goiás, Brazil.

Rev Bras Epidemiol 2015 Apr-Jun;18(2):490-502

Department of Nutrition, Public Health School, Universidade de São Paulo, São Paulo, SP, Brazil.

Objective: This study aimed to assess the nutritional status of vitamin A and associated factors in children assisted in Primary Care Health in Goiânia, Goiás, Brazil.

Methods: This is a cross-sectional study with a sample of 228 children 12 to 16 months of age. The nutritional status of vitamin A was assessed by serum retinol concentration, determined by high performance liquid chromatography. Multiple linear regression models with hierarchical selection of independent variables were used to evaluate the correlation with serum retinol as the dependent variable.

Results: The vitamin A deficiency (retinol < 0,7 μmol/L) was observed in 14,0% of the children. Maternal schooling and hemoglobin concentration were positively correlated with serum retinol concentration, while C-reactive protein showed a negative correlation (R2 = 0,1648).

Conclusion: The vitamin A deficiency in one-year-old children attended in Basic Health Units in Goiânia configures itself as a moderate public health problem. Actions to promote maternal education, morbidity control and prevention of other micronutrient deficiencies are important for prevention and control of the vitamin A deficiency in this population.

Prevalence and factors associated with metabolic syndrome in elderly users of the Unified Health System.

Rev Bras Epidemiol 2014 Dec;17(4):805-17

School of Nutrition, Universidade Federal de Goiás, Goiânia, GO, Brazil.

Objective: To evaluate the prevalence and factors associated with metabolic syndrome in the elderly.

Methods: Cross-sectional study, with 133 individuals randomly selected in the Unified Health System in Goiania, Goiás. The following variables were researched: anthropometric (BMI, waist circumference, fat percentage by Dual X-ray absorptiometry), sociodemographic (gender, age, color, income, marital status and years of schooling), lifestyle (physical activity, smoking and risk alcohol consumption) and food intake (risk and protective foods). The metabolic syndrome was assessed according to harmonized criteria proposed by the World Health Organization (WHO). The combinations were tested by Poisson regression for confounding factors.

Results: The prevalence of metabolic syndrome was 58.65% (95%CI 49.8 - 67.1), with 60.5% (95%CI 49.01 - 71.18) for females and 55.7% (95%CI 41.33 - 69.53) for males. Hypertension was the most prevalent component of the syndrome in both men, with 80.8% (95%CI 64.5 - 90.4), and women, with 85.2% (95%CI 75.5 - 92.1). After the multivariate analysis, only the excess of weight measured by body mass index (prevalence ratio = 1.66; p < 0.01) remained associated with the metabolic syndrome.

Conclusions: The prevalence of metabolic syndrome in this sample was high, indicating the need for systematic actions by health workers in the control of risk factors through prevention strategies and comprehensive care to the elderly.

Factors associated with the feeding practices of the adult population of Goiânia, Goiás, Brazil.

Rev Bras Epidemiol 2014 Jan-Mar;17(1):267-80

Fundação Oswaldo Cruz, São Paulo, SP, Brasil.

This cross-sectional study identified the factors associated with adult feeding practices in Goiânia, the capital of the state of Goiás, in the Midwestern region of Brazil, by means of telephone interviews with 2,002 adults (> 18 years old). Information about demographic aspects, lifestyle, nutritional status, and food consumption was collected, leading to a sum of healthy food choices. It was observed that men and women have an average of two healthy food choices and low frequency of fruit intake (5.4% of men; 8.5% of women), as well as the consumption of legumes and vegetables (18.1% of men; 22.6% of women). The hierarchical multiple regression analysis revealed that the mean healthy food choice among men increases with age and physical practice, and among women, with paid work. The prevalence of unhealthy food choices associated with other risk behaviors favors the development of chronic diseases. Multi-strategy and intersectorial actions are necessary to overcome this situation.

Prevalence and associated factors with abdominal obesity in hemodialysis patients in Goiânia--GO.

J Bras Nefrol 2013 Oct-Dec;35(4):265-72

Introduction: The presence of excess weight, especially visceral obesity contributes to the increased risk of metabolic and cardiovascular complications in patients with chronic kidney disease.

Objective: To determine the prevalence and associated factors with abdominal obesity in patients on hemodialysis (HD).

Methods: Cross-sectional study with 344 patients older than 18 years. Abdominal obesity was defined as waist circumference > 94 cm in men and > 80 cm in women. The independent variables involved socioeconomic, demographic, lifestyle, duration of HD, food consumption and body mass index (BMI). The analysis of associated factors was performed by multiple Poisson regression, remaining in the final model variables with p < 0.05.

Results: The prevalence of abdominal obesity was 44.77% and was more prevalent in women (55.71%) than in men (37.25%), p = 0.001. The end result of the multivariate analysis identified factors associated with abdominal obesity in men and women: age over 40 years, protein intake below 1.2 g/kg/day and BMI > 25 kg/m². In men the economic class D/E remained associated with abdominal obesity, p < 0.05.

Conclusion: There was a high prevalence of abdominal obesity in hemodialysis patients. Age greater than 40 years, lower socioeconomic classes, below the recommended protein intake and overweight were associated with abdominal obesity.

Risk factors associated with high blood pressure in two-to five-year-old children.

Arq Bras Cardiol 2014 Jan 22;102(1):39-46. Epub 2013 Nov 22.

Universidade Federal de Goiás, GoiásGO, Brasil.

Background: Over recent decades, the prevalence of high blood pressure (BP) has increased among children. Several risk factors are involved in the genesis of high BP during childhood, and their early identification can prevent the development of that disease.

Objectives: To assess the prevalence of high BP and associated factors in children.

Methods: Cross-sectional, population-based study, carried out at the household. This study included 276 two- to five-year-old children in the city of Goiânia, state of Goiás, and assessed their BP, sociodemographic characteristics, birth weight, high BP family history, passive smoking, maternal breastfeeding, dietary habits, sedentary lifestyle and nutritional status. Poisson regression was used to assess the association between risk factors and high BP.

Results: Their mean age was 3.1 ± 0.79 years, and high BP and overweight were observed in 19.9% and 11.2% of the children, respectively. Direct association of high BP was identified with age [prevalence ratio (PR) = 2.3; 95%CI: 1.2 - 4.8; p = 0.017] and overweight (PR = 2.0; 95%CI: 1.2 - 3.6; p = 0.014). No other variable associated with high BP.

Conclusions: The prevalence of high BP in children was high. Overweight and younger children had greater prevalence of high BP.

Evaluation of project promoting health in adolescents.

Rev Saude Publica 2013 Apr;47(2):257-65

Secretaria Municipal de Saúde, Diretoria de Atenção à Saúde, Divisão de Atenção às Doenças Crônicas Não Transmissíveis, GoiâniaGO, Brazil.

Objective: Evaluate a program promoting exercise and healthy eating among adolescents.

Methods: This was a cross-sectional study of 911 adolescents aged 13 to 18 years old in public schools in Goiania, Midwestern Brazil, 2010. The participants were divided into two groups: intervention (schools taking part in the Healthy Living, project) and control. The following were deemed to be exercise: displacement, physical education classes in school, physical activity outside school, and leisure-time physical activity. Pupils who totaled 300 or more minutes per week were defined as active. Consuming protective foods five or more days a week was classified as adequate intake. Statistical analyses made using the Chi-square test.

Results: Most adolescents were identified as inactive or insufficiently active, 65.7% in the Intervention Group and 65.2% Control Group, showing no significant differences between groups, and with higher prevalence among girls. Slightly more than half of adolescents consumed health protective foods 5 or more days a week, 56.6% in the Intervention Group and 50.4% in the Control Group (p = 0.373).

Conclusions: There were no differences between schools in the Intervention Group and Control Group with regard to food choices and physical activity. This indicates that the Healthy Living project needs to be reevaluated to improve the effectiveness in achieving its objectives.

Prevalence of cardiovascular risk factors in elderly individuals treated in the Brazilian Public Health System in Goiânia.

Arq Bras Cardiol 2010 Oct 12;95(5):621-8. Epub 2010 Nov 12.

Secretaria Municipal de Saúde de Goiânia, Goiânia, Goiás, Brasil.

Background: Cardiovascular risk factors (CVRF) present a high prevalence and have an impact on the morbimortality of the elderly; however, this question is still unknown by the elderly treated in the Brazilian Public Health System (SUS).

Objective: To investigate the prevalence of CVRF among the elderly treated by SUS in the city of Goiânia, state of Goiás, Brazil.

Methods: Cross-sectional study using a multiple-stage sampling method, carried out through a home-based interview with 418 elderly individuals aged > 60 years treated by SUS in the city of Goiânia, state of Goiás, Brazil. Socioeconomic and demographic data, as well as data on lifestyle, weight, height, waist circumference, blood pressure and medications used were collected. The studied CVRF were: arterial hypertension, diabetes mellitus, total obesity, central obesity, dyslipidemias, smoking, sedentary lifestyle and alcohol consumption. The Chi-square test was used for the analyses of the associations, with significance being set at 5%.

Results: The prevalences of the CVRF were: 80.4% of arterial hypertension; 83.3% of central obesity; 59.8% of sedentary lifestyle; 32.2% of total obesity; 23.4% of dyslipidemias; 19.1% of diabetes mellitus; 10.0% of smoking and 5.9% of alcohol consumption. As for the simultaneity, 2.4% of the elderly did not present CVRF. The simultaneity of two or more CVRF occurred in 87.3% of the elderly and was more frequent among women.

Conclusion: The CVRF occur simultaneously in more than half of the elderly individuals, and the most prevalent ones were: arterial hypertension, central obesity and sedentary lifestyle. It is necessary to foster the strategies of health promotion and prevention of cardiovascular injury in elderly individuals treated by SUS in the city of Goiânia, especially among those with simultaneous CVRF.

[Arterial hypertension and its correlation with some risk factors in a small brazilian town].

Arq Bras Cardiol 2010 Oct 27;95(4):502-8. Epub 2010 Aug 27.

Liga de Hipertensão Arterial, Universidade Federal de Goiás, Goiânia, Goiás, Brasil.

Background: arterial hypertension (AH) is a health problem that affects a large number of undiagnosed or inadequately treated hypertensive individuals and presents a high rate of treatment nonadherence.

Objective: to estimate the prevalence of AH and its correlation with some cardiovascular risk factors among the adult population of the town of Firminopolis, state of Goiás, Brazil.

Methods: descriptive, observational and cross-sectional population-based study of a simple random sample (age > 18 years): standardized questionnaires with blood pressure (BP) measurements (AH criterion: BP > 140 x 90 mmHg), weight, height, Body Mass Index (BMI) and waist circumference (WC). Data were stored (Microsoft Access) and analyzed using Epi-info software.

Results: we evaluated 1,168 individuals, with a predominance of the female sex - 63.2% and a mean age of 43.2 ± 14.9 years. There was a prevalence of overweight in 33.7% of the individuals and obesity in 16.0% of the individuals. There was a prevalence of altered WC in 51.8% demand of smoking in 23.2%. A sedentary life style at work and leisure activities was present in 67.6% and 64.8% of the individuals, respectively, with a higher proportion seen among the women. Alcohol consumption was observed in 33.3% of the sample. The prevalence of AH was 32.7%, higher among the men (35.8%) than among the women (30.9%). A positive correlation with AH was identified with BMI, WC and age range. A negative correlation was observed between AH and level of schooling, with 18.2% of hypertensive individuals with 9 or more years of schooling.

Conclusion: a high prevalence of AH, overweight and WC alteration was identified. The female sex represented a protective factor for the risk of AH. A positive correlation was found between AH and BMI, WC and age range; a negative correlation was identified between AH and level of schooling.

[Surveillance of risk factors for chronic diseases through telephone interviews: experience in Goiânia, Goiás State, Brazil].

Cad Saude Publica 2008 Jun;24(6):1323-33

Faculdade de Nutrição, Universidade Federal de Goiás, Goiânia, Brazil.

This study describes results from a surveillance system for risk factors for chronic non-communicable diseases in 2005 in the city of Goiânia, Goiás State, Brazil. A probabilistic sample (n = 2,002) of the adult population living in households with landline telephones was studied by phone interviews. Factors investigated were: food consumption, physical activity, smoking, alcohol intake, self-reported weight and height, and self-reported medical diagnosis of chronic non-communicable diseases. Prevalence and c(2) values were calculated. The data showed: low consumption (< 5 days/week) of fruits and vegetables (47.1%), high rate of physical inactivity at work (86.6%), in commuting (92.6%), and during leisure time (61.9%), high alcohol consumption (36.5%), and high rates of obesity (10.6%), hypertension (22.4%), dyslipidemia (18.4%), and diabetes (4.4%). Most of the factors were inversely related to schooling and directly related to age (p < 0.05). High prevalence of risk factors for chronic non-communicable diseases was reported. The advantages of this system were: low operational cost and the ability to monitor trends in chronic non-communicable diseases at the local level.

The relationship between body mass index and lifestyle in a Brazilian adult population: a cross-sectional survey.

Cad Saude Publica 2007 Nov;23(11):2694-740

Faculdade de Nutrição, Universidade Federal de Goiás, Rua 49, Goiania, Brasil.

This study focused on adult obesity prevalence in Goiânia, Goiás State, Brazil, and the association between socio-demographic variables, lifestyle, physical activity, eating habits, and food consumption frequency and body mass index (BMI). A cross-sectional study was conducted in 2001 with a sample of 1,252 individuals from 20 to 64 years of age. The association between socio-demographic variables, lifestyle, food consumption, and physical activity and BMI was evaluated by hierarchical multiple linear regression analysis. Obesity prevalence was 10.7% in men and 13.9% in women. In males, age, income, and meat consumption showed a positive association with BMI, while physical activity during leisure time and commuting and the habit of eating > 4 meals per day were inversely associated with BMI. In women, positively associated factors were age, no smoking, and no meat consumption; in contrast, consumption of grains was inversely associated with BMI. High obesity prevalence was observed; active lifestyle coupled with ingestion of more grains and less meat appeared to protect against increased BMI.

[Validity of self-reported weight and height: the Goiânia study, Brazil].

Rev Saude Publica 2006 Dec;40(6):1065-72

Faculdade de Nutrição, Universidade Federal de Goiás, Goiânia, GO, Brasil.

Objective: To assess the validity of self-reported weight and height at the time of diagnosing obesity, and to identify the sociodemographic and individual characteristics that might be a source of information bias.

Methods: This was a cross-sectional population-based study carried out in the city of Goiânia in 2001. Interviews were conducted with 1,023 individuals aged 20-64 years, in their homes, to collect sociodemographic and self-reported weight and height information. On the same occasion, weight and height measurements were made on these individuals. The mean differences and correlation coefficients between self-reported and measured data were calculated according to age, body mass index (BMI), schooling, income and height.

Results: Both the men and women overestimated their heights (p<0.05), by 0.9 cm and 2.2 cm, respectively. There was no difference between self-reported and measured weights, either for the men (-0.44 kg; p=0.06) or for the women (-0.03 kg; p>0.05). The behavior of overestimating height was influenced by age, schooling, height and body mass index. Although this index obtained from the self-reported data was underestimated (p<0.05), by 0.27 kg/m(2) and 0.67 kg/m(2) for men and women respectively, the measured and self-reported data presented a high degree of agreement. Both the sensitivity and specificity of the self-reported body mass index were high, in relation to identifying the measured index.

Conclusions: In epidemiological studies for monitoring the prevalence of excess weight in populations, self-reported weights and heights constitute reliable data, which gives validity to the methodology utilized.

Waist circumference and body mass index as predictors of hypertension.

Arq Bras Cardiol 2006 Oct;87(4):462-70

Liga de Hipertensão Arterial, Goiânia, GO, Brazil.

Objective: To evaluate the association between anthropometric indexes--body mass index (BMI) and waist circumference (WC)--and hypertension, and to evaluate the predictive value of these indexes in detecting hypertension.

Methods: Cross-sectional population study conducted in the city of Goiânia (GO) with a sample of 1,238 adults aged twenty to 64 years, in 2001. Total obesity was defined as BMI > or = 30 kg/m(2); abdominal obesity was defined as level 2 WC > or = 88 cm for women and > or = 102 cm for men, and hypertension was defined as systolic pressure > or = 140 mmHg, or diastolic pressure > or = 90 mmHg, or utilization of hypotensive drugs). Multiple logistic regression analysis was used to evaluate the associations between anthropometric indexes and hypertension. The Receiver Operating Characteristic (ROC) curve analysis was used to evaluate sensitivity and specificity of BMI (> or = 30) and level 2 WC as predictive factors of hypertension, and to determine the best predictive cut-off points for hypertension.

Results: WC was associated with hypertension in both genders. Level 2 WC and BMI > or = 30 kg/m(2) showed a low sensitivity in identifying hypertension. The best predictive cut-off points for hypertension coincided with level 1 WC (> or = 80 cm) and with BMI > or = 25 kg/m(2) (overweight) for women, and were lower than the values of level 1 WC and of overweight for men.

Conclusion: Level 2 WC and BMI > or = 30 kg/m(2) are not adequate to identify the groups at the highest risk of hypertension, since this risk rises with small increases in adiposity.
