Identifying factors that contribute to students' behavior and weight improvements during school-based obesity prevention interventions is critical for the development of effective programs. The current study aims to determine whether the support and resources that adolescent girls received from their families were associated with improvements in physical activity (PA), television use, dietary intake, body mass index (BMI) and body composition during participation in New Moves, a school-based intervention to prevent obesity and other weight-related problems. Adolescent girls in the intervention condition of New Moves (n = 135), and one parent of each girl, were included in the current analysis. At baseline, parents completed surveys assessing the family environment. At baseline and follow-up, 9-12 months later, girls' behaviors were self-reported, height and weight were measured by study staff and body fat was assessed using dual-energy X-ray absorptiometry. Results showed few associations between family environment factors and girls' likelihood of improving behavior, BMI or body composition. These findings suggest that in general, school-based interventions offer similar opportunities for adolescent girls to improve their PA, dietary intake, and weight, regardless of family support.
确定导致学生在基于学校的肥胖预防干预中行为和体重改善的因素对于制定有效的计划至关重要。本研究旨在确定青少年女孩从家庭获得的支持和资源是否与参与新举措期间身体活动（PA）、电视使用、饮食摄入、身体质量指数（BMI）和身体成分的改善相关，新举措是一项预防肥胖和其他与体重相关问题的基于学校的干预措施。本研究分析包括新举措干预条件下的 135 名少女及其每位女孩的一位家长。在基线时，家长完成了评估家庭环境的调查问卷。在基线和随访时（9-12 个月后），女孩们自我报告了她们的行为，研究人员测量了身高和体重，并用双能 X 射线吸收法评估了体脂肪。结果表明，家庭环境因素与女孩改善行为、BMI 或身体成分的可能性之间几乎没有关联。这些发现表明，一般来说，无论家庭支持如何，基于学校的干预措施为青少年女孩提供了改善身体活动、饮食摄入和体重的相似机会。
