Existing evidence suggests that the prevalence of overweight and obesity among prisoners in different settings is high. Evaluating weight change during incarceration would allow for the investigation of whether the prison environment indeed contributes to unfavourable weight changes.
This study aimed to do a systematic review and a meta-analysis of existing evidence regarding weight change during incarceration.
We conducted a systematic literature search by using five different online databases and included grey literature. A total of 16 studies, all conducted in developed countries, were identified. Weight change was computed in 11 of these studies and was self-reported in five studies. Only two studies included youth. In all but 1 of the 11 studies using actual assessment of weight change, there was an increase in body weight or body mass index on average or weight gain occurred among a significant proportion of participants. A meta-analysis of eight of these studies showed an average weight gain of 0.43 (95% CI 0.14, 0.72) lb/week. In all studies including perceived weight change, a high proportion (43% to 73%) of participants reported weight gain during incarceration.
Health promotion activities within prisons should incorporate initiatives aimed at combating unhealthy weight developments.
现有证据表明，不同环境下囚犯超重和肥胖的患病率较高。评估监禁期间的体重变化，可以调查监狱环境是否确实导致体重变化不利。
本研究旨在对关于监禁期间体重变化的现有证据进行系统评价和荟萃分析。
我们使用五个不同的在线数据库和灰色文献进行了系统的文献检索。确定了 16 项研究，均在发达国家进行。其中 11 项研究计算了体重变化，5 项研究报告了自我报告的体重变化。只有两项研究包括青少年。在所有 11 项使用实际体重变化评估的研究中，除了 1 项外，平均体重或体重指数都有所增加，或者大多数参与者体重增加。对其中 8 项研究的荟萃分析显示，平均每周体重增加 0.43（95%CI 0.14, 0.72）磅。在所有包括感知体重变化的研究中，有 43%至 73%的参与者报告在监禁期间体重增加。
监狱内的健康促进活动应纳入旨在对抗不健康体重发展的举措。
