The Nutrition and Enjoyable Activity for Teen Girls (NEAT girls) randomized controlled trial for adolescent girls from disadvantaged secondary schools: rationale, study protocol, and baseline results

Background: Child and adolescent obesity predisposes individuals to an increased risk of morbidity and mortality from a range of lifestyle diseases. Although there is some evidence to suggest that rates of pediatric obesity have leveled off in recent years, this has not been the case among youth from low socioeconomic backgrounds. The purpose of this paper is to report the rationale, study design and baseline findings of a school-based obesity prevention program for low-active adolescent girls from disadvantaged secondary schools. Methods/Design: The Nutrition and Enjoyable Activity for Teen Girls (NEAT Girls) intervention will be evaluated using a group randomized controlled trial. NEAT Girls is a 12-month multi-component school-based intervention developed in reference to Social Cognitive Theory and includes enhanced school sport sessions, interactive seminars, nutrition workshops, lunch-time physical activity (PA) sessions, PA and nutrition handbooks, parent newsletters, pedometers for self-monitoring and text messaging for social support. The following variables were assessed at baseline and will be completed again at 12- and 24-months: adiposity, objectively measured PA, muscular fitness, time spent in sedentary behaviors, dietary intake, PA and nutrition social-cognitive mediators, physical self-perception and global self-esteem. Statistical analyses will follow intention-to-treat principles and hypothesized mediators of PA and nutrition behavior change will be explored. Discussion: NEAT Girls is an innovative intervention targeting low-active girls using evidence-based behavior change strategies and nutrition and PA messages and has the potential to prevent unhealthy weight gain and reduce the decline in physical activity and poor dietary habits associated with low socio-economic status. Few studies have reported the long-term effects of school-based obesity prevention programs and the current study has the potential to make an important contribution to the field

Promoting human wellness: new frontiers for research, practice, and policy

This book is a state-of-the-art educational resource on the latest research and public-policy developments in the fields of wellness promotion and disease prevention. Based on award-winning lectures by University of California faculty on nine campuses as part of the Wellness Lectures Program jointly funded by The California Wellness Foundation, Health Net, and the University of California, the volume aims to widen the scope of health care research and policy to promote wellness rather than focus on illness and disease, and to incorporate proactive, interdisciplinary approaches to health care. The volume also contains chapters by distinguished scholars inthe fields of wellness promotion and disease prevention. Many of these articles fall outside the scope of what we conventionally call health promotion, bringing new perspectives to research and policy possibilities. Promoting Human Wellness is organized around core themes such as the importance of disease prevention programs that address multiple health risks, the link between poverty and minority status and disease susceptibility, and the challenge of evaluating health benefits and cost-effectiveness. The articles discuss such timely issues as genetic determinism as a paradigm in wellness promotion, adolescent health promotion and teen pregnancy prevention strategies, racial differences in cancer epidemiology, the California smokers' helpline, strategies for reducing youth violence, HIV/AIDS prevention, domestic violence education and prevention srategies, and the future of women's health research. Presented within the framework of social ecology, several of the chapters in this volume address new ideas and approaches in the wellness field that are only now beginning to be understood such as the social construction of variables including race, class, and gender. Promoting Human Wellness will be essential reading for health practitioners, policymakers, and others seeking to expand the ways we define and achieve health.

Assessing the perceived environment among minimally active adolescent girls: validity and relations to physical activity outcomes.

This study examined how adolescents' perceptions of exercise resources in the environment relate to physical activity outcomes.Perceptions of the availability and use of environmental resources, vigorous physical activity (VIG), daily energy expenditure (KCAL), lifestyle activities (LA), and cardiovascular fitness (Vo2peak) were assessed cross-sectionally among 87 minimally active adolescent girls (ages 14-17). To validate adolescent reports, the perceived availability of environmental resources was also assessed from 47 parents.Adolescent-parent agreement over the availability of resources was modest for the home domain (r = .62, p < .001) and weak for the community domain (r = .14, p > .05). Adolescents' perceptions of resource availability in both the home and community domains were positively associated with VO2peak (p < .05) but unrelated to VIG, KCAL, and LA. Adolescents' use of home resources was positively correlated with both VIG and LA (p < .05).Minimally active adolescent girls were more attuned to and likely to use the resources for physical activity located in their home environment as opposed to the community environment
