Tracking of fruit, vegetables and unhealthy snacks consumption from childhood to adulthood (15 year period): does exposure to a free school fruit programme modify the observed tracking?

Int J Behav Nutr Phys Act 2019 Feb 15;16(1):22. Epub 2019 Feb 15.

Department of Public Health, Sport and Nutrition, University of Agder, Kristiansand, Norway.

Background: The rationale for promoting increased consumption of fruit and vegetables (FV) at an early age is based on results from previous tracking-studies, indicating that dietary habits learned in childhood sustain into adulthood. Previous tracking studies have several limitations (e.g. Read More

A low-cost Behavioural Nudge and choice architecture intervention targeting school lunches increases children's consumption of fruit: a cluster randomised trial.

Int J Behav Nutr Phys Act 2019 Feb 13;16(1):20. Epub 2019 Feb 13.

The Centre for Activity and Eating Research, Bangor University, School of Psychology, Brigantia, Penrallt Road, Bangor (Gwynedd), Wales, LL57 2AS, UK.

Background: Research has consistently indicated that most children do not consume sufficient fruit and vegetables to provide them with a healthy, balanced diet. This study set out to trial a simple, low-cost behavioural nudge intervention to encourage children to select and consume more fruit and vegetables with their lunchtime meal in a primary school cafeteria.

Methods: Four primary schools were randomly allocated to either the control or the intervention condition and baseline data were collected over two days in each school. Read More

"Responses to the Chilean law of food labeling and advertising: exploring knowledge, perceptions and behaviors of mothers of young children".

Int J Behav Nutr Phys Act 2019 Feb 13;16(1):21. Epub 2019 Feb 13.

Institute of Nutrition and Food Technology, University of Chile, El Líbano, 5524, Santiago, Chile.

Background: In line with calls for action from international health organizations, Chile implemented in June 2016 a set of regulations to tackle the obesity epidemic. The new regulation includes the mandatory use of front-of-package warning labels on packaged foods/beverages high in energy, sugars, saturated fats and sodium. Additionally, such foods cannot be sold nor offered in daycares/schools and cannot be promoted to children under 14yo. Read More

Regulating health and nutrition claims in the UK using a nutrient profile model: an explorative modelled health impact assessment.

Int J Behav Nutr Phys Act 2019 Feb 7;16(1):18. Epub 2019 Feb 7.

Centre on Population Approaches for Non-Communicable Disease Prevention, Nuffield Department of Population Health, University of Oxford, Old Road Campus, Headington, Oxford, OX3 7LF, UK.

Background: Health-related claims (HRCs) are statements found on food packets that convey the nutritional quality of a food (nutrition claims) and/or its impact on a health outcome (health claims). The EU stated that HRCs should be regulated such that they can only appear on foods that meet a specified nutrient profile (NP). A NP model has been proposed, but not agreed by the European Commission. Read More

Changes in diet quality and home food environment in preschool children following weight management.

Int J Behav Nutr Phys Act 2019 Feb 4;16(1):16. Epub 2019 Feb 4.

Division of Behavioral Medicine and Clinical Psychology, Cincinnati Children's Hospital Medical Center, 3333 Burnet Avenue MLC 3015, Cincinnati, OH, 45229, USA.

Background: Family-based obesity treatment interventions can successfully reduce energy intake in preschoolers. An implicit goal of obesity treatment interventions is to improve diet quality, but diet quality has been less examined as a treatment outcome in studies of preschoolers. The purpose of this study was to conduct a secondary analysis comparing the change in diet quality and home food environment in preschoolers assigned to a behavioral family-based obesity intervention (LAUNCH), motivational interviewing (MI) condition, or standard care (STC) condition.

Differential reporting of fruit and vegetable intake among youth in a randomized controlled trial of a behavioral nutrition intervention.

Int J Behav Nutr Phys Act 2019 Feb 1;16(1):15. Epub 2019 Feb 1.

Social and Behavioral Sciences Branch, Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, MD, 20817, USA.

Background: Nutrition interventions typically rely on self-reported intake that may be susceptible to differential reporting bias due to exposure to the intervention. Such differences may result from increased social desirability, increased attention to eating or improved recall accuracy, and may bias estimates of the intervention effect. This study investigated differential reporting bias of fruit and vegetable intake in youth with type 1 diabetes participating in a randomized controlled trial targeting increased whole plant food intake.

Examination of how food environment and psychological factors interact in their relationship with dietary behaviours: test of a cross-sectional model.

Int J Behav Nutr Phys Act 2019 Jan 30;16(1):12. Epub 2019 Jan 30.

Medical Research Council Lifecourse Epidemiology Unit, University of Southampton, Southampton General Hospital Tremona Road, Southampton, SO16 6YD, UK.

Background: To improve population diet environmental strategies have been hailed the panacea because they require little agency or investment of personal resources; this contrasts with conventional strategies that rely on individuals to engage high levels of agency and make deliberate choices. There is an immediate need to improve understanding of the synergy between the psychological and environmental determinants of diet in order to optimise allocation of precious public health resources. This study examined the synergistic and relative association between a number of food environment and psychological factors and the dietary behaviours of a population sample of women with young children.

Assessing the impact of the Barbados sugar-sweetened beverage tax on beverage sales: an observational study.

Int J Behav Nutr Phys Act 2019 Jan 30;16(1):13. Epub 2019 Jan 30.

Centre for Diet and Activity Research, MRC Epidemiology Unit, University of Cambridge, Cambridge, UK.

Background: The World Health Organization has advocated for sugar-sweetened beverage (SSB) taxes as part of a broader non-communicable disease prevention strategy, and these taxes have been recently introduced in a wide range of settings. However, much is still unknown about how SSB taxes operate in various contexts and as a result of different tax designs. In 2015, the Government of Barbados implemented a 10% ad valorem (value-based) tax on SSBs. Read More

Measuring change in trials of physical activity interventions: a comparison of self-report questionnaire and accelerometry within the PACE-UP trial.

Int J Behav Nutr Phys Act 2019 Jan 22;16(1):10. Epub 2019 Jan 22.

Population Health Research Institute, St George's University of London, Cranmer Terrace, Tooting, London, SW17 ORE, UK.

Background: Few trials have compared estimates of change in physical activity (PA) levels using self-reported and objective PA measures when evaluating trial outcomes. The PACE-UP trial offered the opportunity to assess this, using the self-administered International Physical Activity Questionnaire (IPAQ) and waist-worn accelerometry.

Methods: The PACE-UP trial (N = 1023) compared usual care (n = 338) with two pedometer-based walking interventions, by post (n = 339) or with nurse support (n = 346). Read More

Comparison of individuals with low versus high consumption of home-prepared food in a group with universally high dietary quality: a cross-sectional analysis of the UK National Diet & Nutrition Survey (2008-2016).

Int J Behav Nutr Phys Act 2019 Jan 17;16(1). Epub 2019 Jan 17.

MRC Epidemiology Unit & Centre for Diet and Activity Research (CEDAR), University of Cambridge, Box 285, Institute of Metabolic Science, Cambridge Biomedical Campus, Cambridge, CB2 0QQ, UK.

Background: Despite inconclusive evidence, the idea that a lack of home food preparation and skills is a limiting factor in achieving a healthy diet is widespread. Cooking skills interventions proliferate, and several countries now mention cooking in their dietary guidelines. The aim of this study was to determine whether substantial consumption of home-prepared food is necessary for high dietary quality by exploring whether individuals can eat healthily while eating little home-prepared food.

A systematic review of factors that influence food store owner and manager decision making and ability or willingness to use choice architecture and marketing mix strategies to encourage healthy consumer purchases in the United States, 2005-2017.

Int J Behav Nutr Phys Act 2019 Jan 14;16(1). Epub 2019 Jan 14.

Family Nutrition Program, Department of Human Nutrition, Foods, and Exercise, Virginia Tech, Blacksburg, Virginia, USA.

Background: Altering food store environments is a promising approach to encourage healthy product purchases by consumers to improve their diet quality and health. Food store owners and managers are intermediaries to ensure that environmental changes are enacted. Despite their role as gatekeepers to implement and sustain healthy food environment changes, no systematic review has been published that examines food store owner and manager (retailer) data.

Daily domain-specific time-use composition of physical behaviors and blood pressure.

Int J Behav Nutr Phys Act 2019 Jan 10;16(1). Epub 2019 Jan 10.

National Research Centre for the Working Environment, Copenhagen, Denmark.

Background: Previous research has shown contrasting effects on hypertension for occupational and leisure-time physical behaviors-physical activity and sedentary behavior and time in bed. However, (a) none of these studies have addressed the compositional property of the physical behaviors and (b) most knowledge on the association between domain-specific physical behaviors and hypertension relies upon self-reported physical behaviors information primarily on white-collar worker study samples. We aimed to be the first to disentangle the relationship between technically measured 24-h time-use behaviors in work and leisure domains and blood pressure among blue-collar workers using a compositional data analysis approach.

Department of Clinical Epidemiology, Biostatistics and Bioinformatics, Amsterdam UMC, University of Amsterdam, Academic Medical Centre, Meibergdreef 9, Amsterdam, The Netherlands.

Background: The preconceptional period may be an optimal window of opportunity to improve lifestyle. We previously showed that a 6 month preconception lifestyle intervention among women with obesity and infertility was successful in decreasing the intake of high caloric snacks and beverages, increasing physical activity and in reducing weight in the short term. We now report the effects of the preconception lifestyle intervention on diet, physical activity and body mass index (BMI) at 5. Read More

Food banking and emergency food aid: expanding the definition of local food environments and systems.

Int J Behav Nutr Phys Act 2019 Jan 7;16(1). Epub 2019 Jan 7.

Department of Public Health, Environment and Society, London School of Hygiene and Tropical Medicine, 15-17 Tavistock Place, London, WC1H 9SH, UK.

If current trends in food insecurity continue then the diets of low-income people may become characterised by the inclusion of significant amounts of donated and surplus food accessed via the third-sector. These developments have yet to be integrated into macro models and concepts of the food environment. Addressing this caveat is necessary in order to both help build an evidence base to challenge policies that exacerbate the drivers of food insecurity and to inform interventions aimed at improving the diets of disadvantaged populations.

Dietary behaviors throughout childhood are associated with adiposity and estimated insulin resistance in early adolescence: a longitudinal study.

Int J Behav Nutr Phys Act 2018 12 17;15(1):129. Epub 2018 Dec 17.

Division of Chronic Disease Research Across the Lifecourse, Department of Population Medicine, Harvard Medical School and Harvard Pilgrim Health Care Institute, Landmark Center, 401 Park Drive Suite 401, Boston, MA, 02215, USA.

Background: Despite the growing prevalence of excess weight and prediabetes in children, the contributing role of dietary behaviors throughout childhood remains poorly understood. We examined longitudinal associations of dietary behaviors throughout childhood with adiposity and estimated insulin resistance (HOMA-IR) in adolescence.

Methods: Among 995 children from Project Viva, a pre-birth cohort, we examined associations of child dietary behaviors (frequency of eating breakfast, fast food, family dinner, and eating meals while watching television) reported annually throughout childhood (from ages 4 to 11 years) with body mass index z-score (BMI-z; n = 991), waist circumference (WC; n = 995), DXA overall and central adiposity measurements (n = 721), and HOMA-IR (n = 579) in early adolescence (13.

A global systematic scoping review of studies analysing indicators, development, and content of national-level physical activity and sedentary behaviour policies.

Int J Behav Nutr Phys Act 2018 11 28;15(1):123. Epub 2018 Nov 28.

Institute for Health and Sport, Victoria University, Ballarat Road, Footscray, Melbourne, VIC, 3001, Australia.

Background: National policy approaches to physical activity (PA) promotion and sedentary behaviour (SB) reduction are needed to address rising rates of non-communicable diseases. Understanding the policy process and impact through robust research and evaluation is crucial for facilitating successful reforms in national health policy. This scoping review, therefore, aimed to map the evidence on indicators, development, and content of national PA and/or SB policies globally. Read More

Int J Behav Nutr Phys Act 2018 11 27;15(1):121. Epub 2018 Nov 27.

School of Public Health and Health Systems, University of Waterloo, 200 University Avenue West, Waterloo, ON, N2L 3G1, Canada.

Background: School nutrition policies can encourage restrictions in sugar-sweetened beverage (SSB) availability in school food outlets in order to discourage students' SSB intake. The main objective was to examine how beverage availability in school vending machines changes over three school years across schools in distinct school nutrition policy contexts. Secondary objectives were to examine how students' weekday SSB intake varies with time and identify longitudinal associations between beverage availability and SSB intake. Read More

24-h movement behaviors from infancy to preschool: cross-sectional and longitudinal relationships with body composition and bone health.

Int J Behav Nutr Phys Act 2018 11 26;15(1):118. Epub 2018 Nov 26.

Departments of Office of the Dean, Dunedin School of Medicine, University of Otago, Dunedin, New Zealand.

Background: New physical activity guidelines for children address all movement behaviors across the 24-h day (physical activity, sedentary behavior, sleep), but how each component relates to body composition when adjusted for the compositional nature of 24-h data is uncertain.

Aims: To i) describe 24-h movement behaviors from 1 to 5 years of age, ii) determine cross-sectional relationships with body mass index (BMI) z-score, iii) determine whether movement behaviors from 1 to 5 years of age predict body composition and bone health at 5 years.

Methods: 24-h accelerometry data were collected in 380 children over 5-7 days at 1, 2, 3. Read More

Associations of context-specific sitting time with markers of cardiometabolic risk in Australian adults.

Int J Behav Nutr Phys Act 2018 11 20;15(1):114. Epub 2018 Nov 20.

Physical Activity, Metabolic & Vascular Physiology and Behavioural Epidemiology Laboratories, Baker Heart and Diabetes Institute, Level 4, 99 Commercial Rd, Melbourne, VIC, 3004, Australia.

Background: High volumes of sitting time are associated with an elevated risk of type 2 diabetes and cardiovascular disease, and with adverse cardiometabolic risk profiles. However, previous studies have predominately evaluated only total sitting or television (TV) viewing time, limiting inferences about the specific cardiometabolic health impacts of sitting accumulated in different contexts. We examined associations of sitting time in four contexts with cardiometabolic risk biomarkers in Australian adults. Read More

Exploring the emergence and evolution of population patterns of leisure-time physical activity through agent-based modelling.

Int J Behav Nutr Phys Act 2018 11 19;15(1):112. Epub 2018 Nov 19.

University of Sao Paulo School of Public Health, Sao Paulo, Brazil.

Introduction: Most interventions aiming to promote leisure-time physical activity (LTPA) at population level showed small or null effects. Approaching the problem from a systems science perspective may shed light on the reasons for these results. We developed an agent-based model to explore how the interactions between psychological attributes and built and social environments may lead to the emergence and evolution of LTPA patterns among adults.

A functional description of adult picky eating using latent profile analysis.

Int J Behav Nutr Phys Act 2018 11 6;15(1):109. Epub 2018 Nov 6.

Department of Psychology, East Carolina University, East Fifth Street, 104 Rawl Building, Greenville, NC, 27858-4353, USA.

Objective: Research has indicated that adult picky eating (PE) is associated with elevated psychosocial impairment and limited dietary variety and fruit and vegetable intake; however, research operationalizing PE behaviors is limited. Previous research identified a PE profile in children, marked by high food avoidance (satiety responsiveness, fussiness, and slow eating) and low food approach (food enjoyment and responsiveness) appetitive traits. The present study aimed to replicate a similar latent eating behavior profile in an adult sample. Read More

The impact of individual and environmental interventions on income inequalities in sports participation: explorations with an agent-based model.

Int J Behav Nutr Phys Act 2018 11 1;15(1):107. Epub 2018 Nov 1.

Department of Public Health, Erasmus MC, University Medical Center Rotterdam, PO Box 2040, 3000 CA, Rotterdam, The Netherlands.

Background: Income inequalities in sports participation are shaped by a system in which individuals and the environment interact. We developed an agent-based model (ABM) that could represent this system and used it to provide a proof-of-concept of its potential to explore the impact of individual and environmental interventions on reducing inequalities in sports participation.

Methods: Our ABM simulates sports participation of individuals in the Dutch city of Eindhoven. Read More

Short-term efficacy of a computer-tailored physical activity intervention for prostate and colorectal cancer patients and survivors: a randomized controlled trial.

Int J Behav Nutr Phys Act 2018 10 30;15(1):106. Epub 2018 Oct 30.

Department of Psychology and Educational Sciences, Open University of the Netherlands, PO Box 2960, 6401 DL, Heerlen, The Netherlands.

Background: Physical activity (PA) is beneficial in improving negative physical and psychological effects of cancer and cancer treatment, but adherence to PA guidelines is low. Computer-tailored PA interventions can reach large populations with little resources. They match with patients' preference for home-based, unsupervised PA programs and are thus promising for the growing population of cancer survivors. Read More

Profiles of children's physical activity and sedentary behaviour between age 6 and 9: a latent profile and transition analysis.

Int J Behav Nutr Phys Act 2018 10 23;15(1):103. Epub 2018 Oct 23.

Centre for Exercise, Nutrition & Health Sciences, School for Policy Studies, University of Bristol, 8 Priory Road, Bristol, BS8 1TZ, UK.

Background: Physical activity is associated with improved physical and mental health among children. However, physical activity declines and sedentary time increases with age, and large proportions of older children do not meet the recommended hour per day of moderate-to-vigorous-intensity physical activity (MVPA). The aim of this paper is to identify profiles of children based on the complex relationship between physical activity and sedentary time at ages 6 and 9 and explore how those profiles are associated with other covariates and how they change over time.
