Although it is crucial to examine the environmental correlates of physical activity (PA) for developing more effective interventions for overweight populations, limited studies have investigated differences in the environmental correlates on body mass index (BMI). The purpose of the present study was to examine the perceived environmental correlates of PA among normal-weight and overweight Japanese men. Data were analyzed for 1,420 men (aged 44.4 ± 8.3 years), who responded to an internet-based cross-sectional survey of answering the short version of the International Physical Activity Questionnaire and its Environment Module. Binary logistic regression analyses were utilized to examine the environmental factors associated with meeting the PA recommendation (150 minutes/week) between the normal-weight and overweight men. After adjusting for socio-demographic variables, common and different environmental correlates of PA were observed among normal-weight and overweight men. Furthermore, significant interactions regarding PA were observed between BMI status and two environmental correlates: access to public transportation (P = 0.03) and crime safety during the day (P = 0.01). The results indicated that BMI status is a potential moderator between perceived environmental factors and PA and suggested that different environmental intervention approaches should be developed for overweight populations.
尽管研究身体活动（PA）的环境相关性对于为超重人群制定更有效的干预措施至关重要，但有限的研究调查了环境相关性对体重指数（BMI）的差异。本研究旨在研究日本正常体重和超重男性对 PA 的感知环境相关性。对 1420 名男性（年龄 44.4±8.3 岁）进行了数据分析，这些男性通过互联网完成了国际体力活动问卷及其环境模块的简短版本的横断面调查。利用二元逻辑回归分析，在正常体重和超重男性之间，检验与满足 PA 推荐量（150 分钟/周）相关的环境因素。在校正社会人口统计学变量后，在正常体重和超重男性中观察到 PA 的常见和不同环境相关性。此外，在 BMI 状态和两个环境相关性（公共交通可达性（P=0.03）和白天的犯罪安全性（P=0.01）之间观察到 PA 的显著交互作用。结果表明，BMI 状态是感知环境因素与 PA 之间的一个潜在调节因素，并表明应该为超重人群制定不同的环境干预方法。
