Emerging research suggests neighborhood disadvantage is associated with disordered eating (DE; e.g., binge eating, body dissatisfaction) beginning in middle childhood, with effects that increment those of proximal disadvantage (e.g., family income). Understanding factors that contribute to early risk for youth living in disadvantaged neighborhoods is critical because childhood DE predisposes youth to more severe eating disorders in adolescence/adulthood. However, the specific "active ingredients" through which neighborhoods impact DE remain unknown. We examined community violence exposure and limited neighborhood resources (e.g., green spaces, recreational facilities) as two notable neighborhood-level stressors that could contribute to early associations between more distal disadvantage and DE.
Participants included girls and boys oversampled for neighborhood disadvantage from the MSU Twin Registry (N = 2060; M = 8.02; 48.7% female). Analyses used structural equation modeling to examine whether community violence exposure and neighbor informant reports of neighborhood resources were associated with DE after accounting for proximal youth characteristics (e.g., family income, racial identity).
Community violence exposure was significantly associated with DE (b = 0.20, 95% CI [0.14, 0.27]), but neighborhood resources were not (b = 0.04, 95% CI [-0.13, 0.22]). Associations were consistent across multiple potential moderators, including age, sex, racial identity, family income, and body mass index.
Community violence is a significant stressor that may help explain associations between neighborhood disadvantage and DE in youth. Additional research is needed to understand the underlying cognitive, affective, and biological mechanisms through which violence exposure may increase the risk for DE in under-resourced contexts.
新兴研究表明，邻里劣势与童年中期开始出现的饮食失调（如暴饮暴食、身体不满）有关，其影响超过了近端劣势（如家庭收入）。了解导致生活在弱势社区的青少年早期风险的因素至关重要，因为儿童期饮食失调会使青少年在青春期/成年期更容易患上更严重的饮食失调症。然而，邻里环境影响饮食失调的具体“活性成分”仍不清楚。我们研究了社区暴力暴露和有限的邻里资源（如绿地、娱乐设施），作为两个显著的邻里层面压力源，它们可能导致更远端劣势与饮食失调之间的早期关联。
参与者包括从密歇根州立大学双胞胎登记处中因邻里劣势而被过度抽样的女孩和男孩（N = 2060；M = 8.02；48.7%为女性）。分析采用结构方程模型，以检验在考虑近端青少年特征（如家庭收入、种族身份）后，社区暴力暴露和邻里资源的邻居 informant 报告是否与饮食失调有关。
社区暴力暴露与饮食失调显著相关（b = 0.20，95% CI [0.14, 0.27]），但邻里资源与饮食失调无关（b = 0.04，95% CI [-0.13, 0.22]）。在多个潜在调节变量中，包括年龄、性别、种族身份、家庭收入和体重指数，关联都是一致的。
社区暴力是一个重要的压力源，可能有助于解释邻里劣势与青少年饮食失调之间的关联。需要进一步的研究来了解暴力暴露可能在资源匮乏环境中增加饮食失调风险的潜在认知、情感和生物学机制。
