研究社区快餐店密度与居民行为、心理社会和社会人口学特征共同影响老年人肥胖的差异。横断面多层次设计。人口普查区组，作为俄勒冈州波特兰大都会地区城市增长边界内社区的代表。从120个社区中随机抽取1221名居民(平均年龄65岁)，应答率为48%。创建了一种基于地理信息系统的快餐店密度测量方法，覆盖120个社区。对抽样社区的居民进行了身体质量指数(BMI)、光顾当地快餐店的频率、油炸食品消费、体力活动水平、吃水果和蔬菜的自我效能、家庭收入和种族/民族等方面的评估。多水平Logistic回归分析。在快餐店密度高的社区与密度低的社区相比，居民水平的个人特征与肥胖的可能性(BMI≥30)之间存在显著关联：肥胖的优势比[OR]为：每周光顾当地快餐店的95%可信区间[CI]为：1.878(CI=1.006-3.496)；不符合体力活动建议的为1.792(CI=1.006-3.190)；对健康食品的信心较低为1.212(CI=1.057-1.391)；非西班牙裔黑人居民为8.057(CI=1.705-38.086)。社区快餐店密度的增加与不健康的生活方式、较差的心理社会状况和老年人肥胖风险的增加有关。
To examine variation in obesity among older adults relative to the joint influences of density of neighborhood fast-food outlets and residents' behavioral, psychosocial, and sociodemographic characteristics. Cross-sectional and multilevel design. Census block groups, used as a proxy for neighborhoods, within the metropolitan region's Urban Growth Boundary in Portland, Oregon. A total of 1,221 residents (mean age=65 years old) recruited randomly from 120 neighborhoods (48% response rate). A Geographic Information System-based measure of fast-food restaurant density across 120 neighborhoods was created. Residents within the sampled neighborhoods were assessed with respect to their body mass index (BMI), frequency of visits to local fast-food restaurants, fried food consumption, levels of physical activity, self-efficacy of eating fruits and vegetables, household income, and race/ethnicity. Multilevel logistic regression analyses. Significant associations were found between resident-level individual characteristics and the likelihood of being obese (BMI≥30) for neighborhoods with a high-density of fast-food restaurants in comparison to those with a low density: odds ratios [OR] for obesity, 95% confidence interval [CI] were: 1.878 (CI=1.006-3.496) for weekly visits to local fast-food restaurants; 1.792 (CI=1.006-3.190) for not meeting physical activity recommendations; 1.212 (CI=1.057-1.391) for low confidence in eating healthy food; and 8.057 (CI=1.705-38.086) for non-Hispanic black residents. Increased density of neighborhood fast-food outlets was associated with unhealthy lifestyles, poorer psychosocial profiles, and increased risk of obesity among older adults.
