Epidemiol Health 2021 Apr 7:e2021023. Epub 2021 Apr 7.

Yonsei University Graduated School, Department of Public Health, Seoul, Republic of Korea.

Objectives: We analyzed whether gender role stereotypes (GRS) and patriarchal mindset are associated with cognitive function in an elderly community population.

Methods: We utilized data from 580 people enrolled in the Korean Social Life, Health and Aging Project. GRS and patriarchal mindset were measured using a questionnaire. We divided GRS and patriarchal mindset into two groups following their median levels: a conservative mindset and an open mindset. Cognitive function was assessed using the Mini-Mental State Examination, Korean version (MMSE-K). Cognitive impairment was defined as MMSE-K ≤21 points. A multivariable logistic regression was performed, adjusting for sex, age, socio-demographic and lifestyle factors, and social network size. Age and lifestyle factors were stratified.

Results: Compared with open-minded people, those with a more conservative mind regarding gender roles and higher adherence to a patriarchal mindset had adjusted odds ratios of 1.88 (95% confidence interval, CI: 1. 11-3.19) and 1.67 (95% CI: 1.00-2.79) for cognitive impairment, respectively. In the stratified analysis, subgroups with a younger age and good lifestyle maintained a protective association with cognitive impairment.

Conclusion: GRS and patriarchal mindset were marginally significantly associated with cognitive impairment among women in later life.

Risk Factors Influencing the Occurrence and Severity of Symptomatic Dry Eye Syndrome: A Cross-sectional Study.

Ophthalmic Epidemiol 2021 Jan 31:1-7. Epub 2021 Jan 31.

Department of Preventive Medicine, Yonsei University College of Medicine , Seoul, Republic of Korea.

: We aimed to investigate the prevalence and risk factors of dry eye syndrome (DES) among a population-based cohort study.: This cross-sectional study was conducted on 475 subjects (184 men and 291 women) enrolled in the Study Group for Environmental Eye Disease at July 2013. Using the ocular surface disease index (OSDI), we measured the DES severity and defined DES as OSDI score ≥13. Current symptoms of DES and possible risk factors such as body mass index, occupations, comorbidities, exercise, smoking and drinking status were assessed by multivariate logistic regression.: Prevalence of DES was significantly higher in women (52.6%) than in men (41.9%) ( < .001). Compared to white-collar workers, blue-collar workers and unemployed persons showed significantly higher DES prevalence and severity. Compared to those with low BMI (<23.0 kg/m), people with extremely high BMI (≥30.0 kg/m) had significantly higher odds ratio (OR) of having DES after fully adjusted for sex, age, hypertension, diabetes, menopausal status, hormone replacement therapy, occupation, and lifestyle factors (OR: 2.83, 95% confidence interval: 1.04-7.71).: We found some novel factors which have been unknown to the relationship with DES through the five years observation of the cohort. The positive associations of unemployment status, blue-collar work, alcohol habit, and obesity with DES suggests a person's comprehensive condition, not individual factors, contribute significantly in developing DES. Further studies will be helpful to understand the underlying mechanisms.

Prevalence of and factors related with abnormal fundoscopic findings among the elderly population in a rural community in South Korea.

Semin Ophthalmol 2020 Jan 6;35(1):41-49. Epub 2020 Feb 6.

Cardiovascular and Metabolic Diseases Etiology Research Center, Seoul, Republic of Korea.

We aimed to report the results of fundus photography ophthalmic examinations among older adults in a rural community in South Korea. We used data from the Korean Social Life, Health, and Aging Project cohort study, which was designed to examine the entire population of individuals aged 60 years or older and their spouses living in a rural of Ganghwa Island, South Korea. At baseline, a total of 860 people was targeted as the study population. From December 2011 to January 2019, five health examinations were conducted, including baseline and follow-up tests. During the fifth wave of the study, we performed fundus photography to assess eye health. Ophthalmic and physical examinations were conducted for 387 people who participated in the fifth wave by trained researchers. Systemic factors were evaluated via blood and diagnostic tests. After excluding , a total of 379 participants was included for analysis. We classified the participants into two groups with either no (zero) or one or more suspicious ophthalmic diseases. The abnormalities included media opacity, suspected glaucoma, and suspicion of retinal disease as diagnosed by trained specialist. We further categorized ophthalmic conditions as clinically insignificant, follow-up needed, semi-urgent, and urgent conditions. We included 379 participants, of which 225 (59.4%) were women. The mean age of the participants was 76.4 ± 6.2 years. Among all participants, 81% (n=307) had one or more abnormalities on fundus screening. Older age, living alone, high blood pressure, and high fasting insulin were associated with an increased risk of having ≥ one eye disease. In terms of triage, 3.7% (n= 14) of the observed conditions were urgent, and 25.9% (n= 98) were semi-urgent. Therefore, we documented fundoscopy results among the elderly population in a rural community in South Korea. Elderly people living alone were more likely to have eye disease. Policies to improve eye health are needed to prevent vision loss in this population.

Association between estimated glomerular filtration rate (eGFR) and asymmetric dimethylarginine (ADMA) concentrations among the elderly in a rural community: a cross-sectional study.

BMC Geriatr 2019 12 23;19(1):370. Epub 2019 Dec 23.

Cardiovascular and Metabolic Diseases Etiology Research Center, Seoul, Republic of Korea.

Background: Reduced glomerular filtration rate and increased asymmetric dimethylarginine (ADMA) are prevalent in elderly people. However, most of the studies that have examined the association between the two conditions were performed in patients with renal dysfunction, but not in the general elderly population. Thus, we investigated an association between estimated glomerular filtration rate (eGFR) and ADMA concentration among community-dwelling older Koreans.

Methods: A cross-sectional study was conducted on 269 men and 382 women (mean age, 71.6 years) enrolled in the Korean Social Life, Health, and Aging Project (KSHAP), a population-based cohort study of health determinants in elderly Koreans. We calculated eGFR using chronic kidney disease- Epidemiology Collaboration Group (CKD-EPI) equation. ADMA concentration was measured by an enzyme-linked immunosorbent assay. The association between eGFR and ADMA concentrations was analyzed by multiple linear regression models.

Results: The mean ADMA was significantly higher in people with eGFR< 60 mL/min/1.73m (0.691 μmol/L) than in those with eGFR≥60 mL/min/1.73m (0.667 μmol/L, p = 0.013). The negative correlations between eGFR level and ADMA concentrations were significant in men and women after adjusted age. After adjusting for potential confounders which were sex, age, body surface, blood pressure, total and HDL cholesterol, diabetes, smoking, and drinking, eGFR levels were inversely associated with ADMA concentrations both in men (β = - 0.0015, p = 0.005) and women (β = - 0.001, p = 0.039).

Conclusion: Our findings suggest that an inverse association exists between eGFR and ADMA concentrations among the Korean elderly in a rural community.

Association Between Dyslipidemia and Dry Eye Syndrome Among the Korean Middle-Aged Population.

Cornea 2020 Feb;39(2):161-167

Cardiovascular and Metabolic Diseases Etiology Research Center, Seoul, Republic of Korea.

Purpose: Dry eye syndrome (DES) is a common eye disease caused by tear deficiency or excessive tear evaporation. Because the tear film layers play a major role in the pathogenesis of the evaporative dry eye, some previous articles have suggested the possible mechanism of dyslipidemia and DES. However, the previous results were inconsistent and few studies were conducted to find the independent relationship between dyslipidemia and DES. Therefore, we investigated the association of dyslipidemia with DES in middle-aged Korean adults.

Methods: This study was conducted on 2272 participants (854 men and 1418 women) enrolled in the Study Group for Environmental Eye Disease (2013-2017) after excluding people who have taken lipid-lowering medication. Participants with total cholesterol ≥240 mg/dL or high-density lipoprotein cholesterol <40 mg/dL or low-density lipoprotein cholesterol ≥160 mg/dL or triglycerides ≥200 mg/dL are defined as having dyslipidemia. Using the ocular surface disease index, we measured the DES severity and defined DES as an ocular surface disease index score ≥13.

Results: Men with dyslipidemia had an odds ratio of 1.29 (95% confidence interval, 0.97-1.71) for DES in an unadjusted model compared with those without DES. After adjusting for age, body mass index, hypertension, diabetes, occupations, smoking and drinking status, exercise, contact lens use, computer use, study cohorts, and calendar year of examinations, the adjusted odds ratio for DES was 1.40 (1.03-1.90) in men. However, there was no significant association between dyslipidemia and DES in women, even after stratifying by menopausal status.

Conclusions: Our findings suggest that dyslipidemia may be associated with the prevalence of DES in Korean men, but not in women.

Comparison of self-reported and accelerometer-assessed measurements of physical activity according to socio-demographic characteristics in Korean adults.

Epidemiol Health 2018 29;40:e2018060. Epub 2018 Nov 29.

Cardiovascular and Metabolic Diseases Etiology Research Center, Yonsei University College of Medicine, Seoul, Korea.

Objectives: Previous studies have shown relatively low correlations between self-reported and accelerometer-assessed physical activity (PA). However, this association differs by socio-demographic factors, and this relationship has not been fully investigated in the general population. Thus, we investigated the correlation between self-reported and accelerometer-assessed PA and whether it differed by demographic and socioeconomic factors among the Korean general population.

Methods: This cross-sectional study included 623 participants (203 men and 420 women) aged 30 to 64 years, who completed a PA questionnaire and wore a wrist-worn accelerometer on the non-dominant wrist for 7 days. We examined the agreement for metabolic equivalent task minutes per week (MET-min/wk) between the 2 measures and calculated Spearman correlation coefficients according to demographic and socioeconomic factors.

Results: The kappa coefficient between tertiles of self-reported and accelerometer-assessed total MET-min/wk was 0.16 in the total population, suggesting overall poor agreement. The correlation coefficient between the 2 measurements was 0.26 (p<0.001) in the total population, and the correlation tended to decrease with increasing age (p for trend <0.001) and depression scores (p for trend <0.001).

Conclusions: We found a low correlation between self-reported and accelerometer-assessed PA among healthy Korean adults, and the correlation decreased with age and depression score. When studying PA using accelerometers and/or questionnaires, age and depression need to be considered, as should differences between self-reported and accelerometer-assessed PA.

Association between vitamin D status and asymmetric dimethylarginine (ADMA) concentration in the Korean elderly population.

Maturitas 2017 Aug 10;102:13-17. Epub 2017 May 10.

Department of Sociology, Yonsei University College of Sociology, Republic of Korea.

Objectives: Vitamin D deficiency has been reported to be associated with the risk of cardiovascular disease. We investigated the relationship between vitamin D status and asymmetric dimethylarginine (ADMA) concentration, a marker of endothelial dysfunction, in the Korean elderly population.

Study Design: A cross-sectional study was conducted on 269 men and 382 women (mean age, 71.6 years) enrolled in the Korean Social Life, Health, and Aging Project (KSHAP), a population-based longitudinal study of health determinants in elderly Koreans. We stratified patients by vitamin D status into three groups according to serum 25-hydroxyvitamin D [25(OH)D] level: sufficient (≥30ng/mL, n=25), insufficient (10-<30ng/mL, n=516), and deficient (<10ng/mL, n=110). To measure endothelial dysfunction, ADMA concentration was assayed by high-performance liquid chromatography. The association between 25(OH)D status and ADMA concentration was analyzed by multiple linear regression models.

Results: The mean ADMA concentration was significantly higher in the insufficient 25(OH)D group (0.665μmol/L, p=0.001) and the deficient 25(OH)D group (0.734μmol/L, p<0.001) compared with the sufficient 25(OH)D group (0.589μmol/L). Even after adjusting for sex, age, body mass index, blood pressure, diabetes mellitus, total and HDL cholesterol, estimated glomerular filtration rate (eGFR), smoking status, and drinking status, ADMA concentrations were higher in the insufficient group (β=0.0742μmol/L, p=0.001) and the deficient group (β=0.1417μmol/L, p<0.001) compared than in the sufficient group. In a sex-stratified analysis, 25(OH)D deficiency was associated with higher ADMA levels in both women (p<0.001) and men (p=0.007), while 25(OH)D deficiency was associated with higher ADMA levels in women (p<0.001) but not in men (p=0.631).

Conclusion: Our findings suggest that low serum 25(OH)D level may be associated with endothelial dysfunction in elderly Korean people.
