居住在低收入社区的人肥胖率、2型糖尿病和心脏新陈代谢疾病的比例高得不成比例。邻里之间的安全感可能会影响压力和体力活动，从而对心脏代谢健康产生连锁影响。在这项研究中，我们在密歇根州底特律的低收入、高空置率社区调查了白天步行时的安全感与心理健康[感知压力(PSS)、抑郁评分]、中等到剧烈的体力活动(PA)、身体质量指数(BMI)和血红蛋白A1C(A1C)之间的关系。我们招募了69名佩戴加速计一周的成年人，并完成了一项关于人口统计学、心理健康和邻里观念的调查。收集人体测量学数据，使用A1CNow试纸测量A1C。我们收集了全市空置建筑和地块的空间数据。我们拟合了传统和多水平回归模型来预测每个结果，使用白天步行时的感知安全性作为感兴趣的自变量，以及个人或个人和社区水平的协变量(例如，空置地块的数量)。最后，我们根据人们的安全感检查了社区特征的趋势。在这个以非裔美国人为主的样本中(91%)，47%的人在白天散步时感到不安全。完全调整后，安全感显著预测抑郁评分(β = − 2.2 2，p = 0.017)、抑郁评分(β = − 4.2 2，p = 0.006)和体重指数(β = − 2.87，p = 0.0 1)。对于PA，我们检测到仅与性有关的显著关联。对于A1C，我们发现与家附近的枯萎地段有显著关联。那些感到不安全的人生活在公园面积和受损地段数量较高的社区。未来的研究需要评估一条关键途径，通过这条途径，包括空置或质量差的绿地在内的社区特征可能会通过减轻压力和伴随对心脏代谢健康的影响来影响肥胖。
Individuals living in low-income neighborhoods have disproportionately high rates of obesity, Type-2 diabetes, and cardiometabolic conditions. Perceived safety in one’s neighborhood may influence stress and physical activity, with cascading effects on cardiometabolic health. In this study, we examined relationships among feelings of safety while walking during the day and mental health [perceived stress (PSS), depression score], moderate-to-vigorous physical activity (PA), Body Mass Index (BMI), and hemoglobin A1C (A1C) in low-income, high-vacancy neighborhoods in Detroit, Michigan. We recruited 69 adults who wore accelerometers for one week and completed a survey on demographics, mental health, and neighborhood perceptions. Anthropometrics were collected and A1C was measured using A1CNow test strips. We compiled spatial data on vacant buildings and lots across the city. We fitted conventional and multilevel regression models to predict each outcome, using perceived safety during daytime walking as the independent variable of interest and individual or both individual and neighborhood-level covariates (e.g., number of vacant lots). Last, we examined trends in neighborhood features according to perceived safety. In this predominantly African American sample (91%), 47% felt unsafe during daytime walking. Feelings of perceived safety significantly predicted PSS (β = − 2.34, p = 0.017), depression scores (β = − 4.22, p = 0.006), and BMI (β = − 2.87, p = 0.01), after full adjustment. For PA, we detected a significant association for sex only. For A1C we detected significant associations with blighted lots near the home. Those feeling unsafe lived in neighborhoods with higher park area and number of blighted lots. Future research is needed to assess a critical pathway through which neighborhood features, including vacant or poor-quality green spaces, may affect obesity—via stress reduction and concomitant effects on cardiometabolic health.
