Food reward sensitivity may influence susceptibility to overeating in a permissive food environment, contributing to unintended weight gain and intentional weight loss behavior. This study examined associations of food reward sensitivity, assessed by the Power of Food Scale (PFS), with weight outcomes and dieting in a nationally representative cohort of U.S. emerging adults. Wave 5 (W5, 5th year of...
The primary aim of the present study was to examine whether parental monitoring, as reported by adolescents and their parents, predicts more or less favorable trajectories of disordered eating behavior and attitudes over the course of one year in a sample of adolescent males and females. An additional aim was to explore whether these trajectories vary when study analyses are limited to females. Participants...
Adolescents spend up to 6–8 h/day in sedentary screen behaviour and screen time is an independent risk factor for obesity. However, the mechanisms by which screen time confers obesity risk remain unclear. Via community level recruitment this study examined whether the relationship between screen time behaviours and body mass index (BMI: kg/m2) was mediated by total energy intake or macronutrient consumption...
Food literacy has been identified as a promising approach to support healthy dietary behaviours in adolescents. However, adolescents' perspectives on food literacy and the impact it could have on their dietary behaviours are not well understood. This study explored adolescents' perspectives on the potential for food literacy to influence their dietary behaviours. Fifteen focus groups were conducted...
The high school setting has been identified as an ideal setting to teach adolescents about healthy dietary behaviours. This study explored home economics teachers' (HETs) views on the role of high schools in enhancing adolescents' food literacy and promoting healthy dietary behaviours. Semi-structured interviews with 22 HETs were conducted. The interview questions focused on the perceived strengths/opportunities...
Eating disorders pose risks to health and wellbeing in young adolescents, but prospective studies of risk factors are scarce and this has impeded prevention efforts. This longitudinal study aimed to examine risk factors for eating disorder symptoms in a population-based birth cohort of young adolescents at 12 years.Participants from the Gateshead Millennium Study birth cohort (n = 516; 262 girls and...
We examine the link between maternal nutrition knowledge and nutritional outcomes of children and adolescents (5–18 years) measured in terms of height-for-age Z-scores (HAZ). One particular focus is on the role of different types of nutrition knowledge. The analysis builds on household-level and individual-level data collected in urban Kenya in 2012 and 2015. Various regression models are developed...
Dietary patterns have contributed to the rising prevalence of overweight and obesity among Indian adolescents. Yet there are limited studies on their perspectives on healthy eating. The purpose of this study was to understand perceptions and attitudes of Indian-origin adolescents in India and Canada that may contribute to healthy eating behaviour.Qualitative data collection and analysis of 13 focus...
To test the prediction that poor decision-making would predict poor eating-related behaviours, which in turn would relate to elevated body mass index (BMI) percentile.Associations among decision-making ability, eating behaviours, and BMI percentile were examined in a sample of 311 healthy male and female adolescents, aged 14–18 years. Structural equation modelling was used to test the proposed relationships...
Hyperpalatable foods are highly pleasurable and possess a heightened capacity to stimulate eating. Adolescents appear especially vulnerable to hyperpalatable foods. These foods are typically high in sugar, fat, or both, but the specific elements that underlie their increased consumption are still not clearly understood. Combinations of high fat and high sugar may particularly intensify overeating...
This study aimed to compare answers given by parents and their adolescent children to the Portuguese version of the Parent Mealtime Action Scale (PMAS) and to assess associations among the reported behaviors. To compare these answers, a cross-sectional study was conducted in a sample of 72 patients of the Obesity Clinic of the Division of Nutrology of the Pediatrics Department at the Federal University...
Bariatric surgery is established as a treatment option for adolescents with severe obesity. Little is known about binge eating (BE) and other eating-related problems in adolescents undergoing bariatric surgery. BE, emotional eating, uncontrolled eating, and cognitive restraint were assessed at baseline, and one and two years after gastric bypass using questionnaires in 82 adolescents (mean age 16...
