Abstract：
OBJECTIVE: Though research indicates that certain aspects of adverse neighborhood conditions may influence weight development in childhood and adolescence, it is unknown if the Child Opportunity Index (COI), a composite measure of 29 indicators of neighborhood conditions, is associated with weight outcomes in adolescence. We hypothesized that lower COI would be associated with higher overweight and obesity in cross-sectional and longitudinal modeling in a national sample of 9 year olds and 10 year olds and that this association would be different by sex.
METHODS: Using data from the Adolescent Brain Cognitive Development study (n = 11,857), we examined the cross-sectional association between COI quintile and overweight and obesity in 9 year olds and 10 year olds. Additionally, we used hazard ratios to examine incident overweight and obesity across three waves of data collection.
RESULTS: Due to the interaction between sex and COI (p < .05), we present sex-specific models. There was a stepwise bivariate association, in which higher COI was associated with lower obesity prevalence. This pattern held in multilevel models, with a stronger association in females. In models adjusted for individual and household characteristics, female adolescents in the lowest quintile COI neighborhoods had 1.81 (95% confidence interval: 1.32, 2.48) times the odds of obesity compared to those in the highest quintile. In longitudinal models, the COI was associated with incident obesity in females only: adjusted hazard ratio = 4.27 (95% confidence interval: 1.50, 12.13) for lowest compared to highest COI.
CONCLUSIONS: Neighborhood opportunity is associated with risk of obesity in pre-adolescence into mid-adolescence. Females may be particularly influenced by neighborhood conditions.

摘要：
目标：虽然研究表明，不良邻里状况的某些方面可能会影响儿童和青少年的体重发育，尚不清楚儿童机会指数(COI)29个邻域条件指标的综合度量，与青春期的体重结果有关。我们假设，在9岁和10岁的全国样本中，在横截面和纵向模型中，较低的COI将与较高的超重和肥胖相关，并且这种关联因性别而异。
方法：使用来自青少年大脑认知发育研究的数据（n=11,857），我们研究了9岁和10岁儿童COI五分位数与超重和肥胖之间的横断面关系.此外,我们使用风险比在三波数据收集中检查超重和肥胖事件.
结果：由于性别与COI之间的相互作用（p<.05），我们展示了特定性别的模型。有一个逐步的双变量关联，其中较高的COI与较低的肥胖患病率相关。这种模式在多层次模型中保持不变，与女性有更强的联系。在针对个人和家庭特征进行调整的模型中，在COI最低的五分之一区,女性青少年的肥胖几率是最高的五分之一区的1.81倍(95%置信区间:1.32,2.48).在纵向模型中，COI仅与女性肥胖相关:最低与最高COI的校正风险比=4.27(95%置信区间:1.50,12.13).
结论：邻里机会与青春期前至青春期中期的肥胖风险相关。女性可能特别受到邻里条件的影响。
