The impact of obesogenic environments on adolescent health is poorly understood. This study examines if neighbourhood features related to physical activity are also related to unhealthy weight status. Adolescents (N=4587, age 15-17 years, 51.4% male) self-reported physical activity and neighbourhood perceptions. Trained researchers measured height and weight. Logistic regression identified if neighbourhood perceptions predicted overweight or obesity. Adolescents who reported convenient physical activity facilities were 2% less likely to be overweight/obese and 5% less likely to be obese, controlled for socio-demographic variables and clustering by school. Physical activity does not appear to directly influence or mediate the relationship between perceived convenient facilities and weight status.
致胖环境对青少年健康的影响目前还知之甚少。本研究探讨与体育活动相关的邻里环境特征是否也与不健康的体重状况有关。青少年（N = 4587，年龄15 - 17岁，男性占51.4%）自我报告了体育活动情况和对邻里环境的看法。经过培训的研究人员测量了身高和体重。逻辑回归分析确定了邻里环境看法是否能预测超重或肥胖情况。在控制了社会人口统计学变量并按学校进行聚类分析后，报告称有便利体育活动设施的青少年超重/肥胖的可能性降低了2%，肥胖的可能性降低了5%。体育活动似乎并未直接影响或介导感知到的便利设施与体重状况之间的关系。
