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.
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.

儿童和青少年肥胖会使个体面临多种生活方式疾病的发病率和死亡率增加的风险。尽管有一些证据表明，近年来儿童肥胖率已经趋于平稳，但来自社会经济背景较低的青少年却并非如此。本文旨在报告一项针对来自弱势中学的低活跃少女的基于学校的肥胖预防计划的基本原理、研究设计和基线结果。
方法/设计：营养和愉快活动的青少年女孩（NEAT Girls）干预措施将使用群组随机对照试验进行评估。NEAT Girls 是一种为期 12 个月的多成分基于学校的干预措施，是参照社会认知理论制定的，包括增强的学校体育课程、互动研讨会、营养研讨会、午餐时间体育活动（PA）课程、PA 和营养手册、家长通讯、计步器进行自我监测和短信提供社会支持。在基线时评估了以下变量，并将在 12 个月和 24 个月时再次完成：肥胖程度、客观测量的 PA、肌肉力量、久坐行为时间、饮食摄入量、PA 和营养社会认知介体、身体自我感知和整体自尊。统计分析将遵循意向治疗原则，并将探索 PA 和营养行为改变的假设介体。
NEAT Girls 是一种针对低活跃女孩的创新干预措施，使用基于证据的行为改变策略和营养和 PA 信息，有潜力预防不健康的体重增加，并减少与社会经济地位较低相关的体力活动下降和不良饮食习惯。很少有研究报告基于学校的肥胖预防计划的长期效果，而本研究有可能为该领域做出重要贡献。
