Being overweight or obese (overweight/obesity) or physically aggressive in childhood and adolescence can have lifelong consequences, hence are important public health problems. Identifying a relationship between these problems would assist in understanding their developmental origins. The present paper sought to review previous studies and use…

Approximately one in four Australian children aged 5-17 years are overweight or obese. Most of the health effects of overweight and obesity in childhood do not eventuate until into adulthood; therefore, motivation for children to have a healthy diet may be low. This scoping review examined the literature for associations between diet quality in…

Weight status on children and youth with autism spectrum disorder is limited. We examined the prevalence of overweight/obesity in children and youth with autism spectrum disorder, and associations between weight status and range of factors. Children and youth with autism spectrum disorder aged 2-16 years (n = 208) and their parents participated in…

Risk factors for adolescent overweight and obesity include low levels of physical activity, high levels of sedentary behavior, low fruit and vegetable intake, and low socioeconomic position (SEP). To date, the vast majority of research investigating associations between lifestyle behaviors and weight status analyze dietary and time use factors…

The way an individual uses one's time can greatly affect his or her health. The purpose of this article was to examine the cross-sectional cross-elasticity relationships for use of time domains in a sample of Australian adolescents. This study analyzed 24-hour recall time use data collected using the Multimedia Activity Recall for Children and…

Purpose: The aim of this study was to test the hypothesized structural paths in Bandura's social-cognitive theory (SCT) model on adolescent girls' physical activity following a 12-month physical activity and dietary intervention to prevent obesity. Method: We conducted a 12-month follow-up study of 235 adolescent girls ("M[subscript…

The influence of parental and early childhood factors on adolescent obesity was investigated using a longitudinal model of body mass index (BMI) from birth to 14 years. Trajectories of BMI using linear mixed model (LMM) analysis were used to investigate the influence of early parental and childhood factors on BMI at 14 years in the Raine birth…

The purpose of this study was to establish sex-specific criterion-referenced standards for pedometer-determined physical activity related to body mass index (BMI)-defined weight status among youth. We analyzed data from 7-16-year-old boys (n = 338) and girls (n = 337) and used pedometer-assessed physical activity and anthropometric data to derive…

Objective: Examine associations between parental concern about adolescent weight and adolescent perceptions of their dietary intake, home food availability, family mealtime environment, and parents' feeding practices. Design: Cross-sectional study. Setting: Adolescents, aged 12-15 years from 37 secondary schools in Victoria, Australia, and their…

This study examines the relationship between body image and obesity, among 4367 indigenous and Anglo-European adolescents in Australia in 2006. It shows that indigenous adolescents, male and female, were more likely than their non-indigenous counterparts to desire and pursue weight gain. Indigenous males showed the greatest tendencies to gain…

Approaches to weight management have traditionally focussed on caloric intake versus caloric expenditure. Despite a range of interventions based on these approaches, the proportion of overweight children and adolescents continues to rise. There are increasing indications that other factors, such as sleep duration, may be at play. This commentary…

Aim: To describe sports participation in Australian adolescents. Method: Use of time, demographic, pedometer and anthropometric data were collected on a random sample of 2200 9-16 year olds. Results: Moderate-to-vigorous physical activity (MVPA) constituted 29% of all energy expenditure, and sport 58% of MVPA energy expenditure. Sports…

This paper provides an overview of current trends in the mental health problems of Australia's youth and adolescents. It presents information derived from the most recent and comprehensive Australian surveys of youth mental health, and provides international comparisons and views from professional practice where relevant. An update of trends for…

A large national study of schoolchildren aged 6-18 years was conducted to assess nutritional and socio-cognitive factors associated with body mass index (BMI). A questionnaire was used to assess nutritional quality of breakfast, importance of physical activity and food variety score, among 4441 students from randomly selected schools in all states…
