Although personal determinants of exercise behavior have been studied extensively, few investigators have examined the influence of the physical environment on exercise habits. A random sample of 2,053 residents of San Diego, CA, were surveyed regarding exercise habits and other variables. A total of 385 exercise facilities in San Diego were classified into categories of either free or pay. After the addresses of respondents and facilities were located on a grid-map and coded, the density of exercise facilities around each respondent's home address was computed. Subjects who reported engaging in three or more exercise sessions per week reported a statistically greater density of pay facilities near their homes than did those who reported no exercise sessions, after controlling for age, education, and income. The finding suggests an association between proximity of exercise facilities and frequency of exercise.
尽管对运动行为的个人决定因素已进行了广泛研究，但很少有研究者考察物理环境对运动习惯的影响。对加利福尼亚州圣地亚哥市2053名居民的随机样本进行了关于运动习惯及其他变量的调查。圣地亚哥市总共385个运动设施被分为免费或付费两类。在将受访者和设施的地址标注在网格地图上并编码后，计算了每个受访者家庭住址周围运动设施的密度。在控制了年龄、教育程度和收入因素后，报告每周进行三次或更多次运动的受试者称其家附近付费设施的密度在统计学上显著高于那些报告不运动的受试者。这一发现表明运动设施的 proximity与运动频率之间存在关联。 （注：原文中“proximity”未翻译，可能是笔误，应改为“ximity”为“接近度”之意，这里按“接近度”翻译）
