Equivocal findings on crime as a deterrent for physical activity may be due to effects of geographic scale on exposure measurement. To investigate this hypothesis, physical activity was measured in 203,883 Australians and linked to standardised crime counts within small ('Census Collection Districts'; approx. 330 residents) and larger areas ('Statistical Local Areas'; approx. 32,000 residents). A median rate ratio of 2.26 indicated substantive geographic variation in moderate-to-vigorous physical activity (MVPA). Adjusting for confounders, multilevel negative binomial regression reported lower MVPA with more crime consistently in small, but not in larger areas. Reducing small pockets of local crime may encourage more physically active lifestyles.
关于犯罪作为身体活动威慑因素的不确定研究结果，可能是由于地理尺度对暴露测量的影响。为了探究这一假设，对203,883名澳大利亚人的身体活动进行了测量，并将其与小区域（“人口普查收集区”；约330名居民）和大区域（“统计当地地区”；约32,000名居民）内的标准化犯罪计数相关联。中位数率比为2.26，表明中度至剧烈身体活动（MVPA）存在实质性的地理差异。在对混杂因素进行调整后，多水平负二项回归显示，在小区域内，犯罪率越高，MVPA持续越低，但在大区域内并非如此。减少局部小范围的犯罪可能会鼓励更积极的生活方式。
