There is a lack of evidence regarding chronic disease modifiable risk factors among prisoner populations in Latin America. The purpose of this study was to estimate the prevalence of modifiable risk factors for chronic diseases and to assess their relationship with length of incarceration.
We analysed data from a cross sectional study in which 4241 prisoners were randomly selected to answer a questionnaire with socio-demographic and health behaviour content using an audio computer-assisted self-interview format. Physical activity (PA), low-quality diet, current smoking and alcohol or cocaine use during the last month in prison were our main outcomes. Quantile regression models and logistic regression models were performed.
Our final analytical sample consisted of 3774 prisoners from four Mexico City prisons. PA was estimated as 579 median metabolic equivalents-min/week, prevalence of alcohol use was 23.4%, cocaine use was 24.2% and current smoking was 53.2%. Our results suggest that, as length of incarceration increased, PA as well as alcohol and cocaine use increased, whereas the quality of diet decreased.
This study supports the hypothesis that exposure to prison environment (measured by length of incarceration) fosters modifiable risk factors for chronic diseases, particularly diet quality and cocaine use.
在拉丁美洲的囚犯群体中，缺乏关于慢性病可改变风险因素的证据。本研究的目的是评估慢性病可改变风险因素的流行率，并评估其与监禁时间的关系。
我们分析了一项横断面研究的数据，该研究中，4241 名囚犯被随机抽取，以音频计算机辅助自我访谈的形式回答一份包含社会人口统计学和健康行为内容的问卷。我们的主要结局是监狱内最后一个月的身体活动（PA）、低质量饮食、当前吸烟和酒精或可卡因使用。我们进行了分位数回归模型和逻辑回归模型分析。
我们的最终分析样本包括来自墨西哥城四个监狱的 3774 名囚犯。PA 估计为 579 中位数代谢当量-min/周，酒精使用的患病率为 23.4%，可卡因使用为 24.2%，当前吸烟为 53.2%。我们的研究结果表明，随着监禁时间的增加，PA 以及酒精和可卡因的使用增加，而饮食质量下降。
本研究支持了这样一种假设，即监狱环境的暴露（通过监禁时间来衡量）促进了慢性病的可改变风险因素，特别是饮食质量和可卡因使用。
