Prevalence and factors associated with tobacco use in women deprived of liberty in a prison in the Brazilian Midwest

Abstract Tobacco use is a Public Health issue, and the release of its use in the prison system is controversial. Its prevalence in this population is high, including in women’s prisons. The objective of this article is to estimate tobacco use prevalence in women deprived of liberty and its associated factors. Cross-sectional study with 259 participants who answered a questionnaire in a prison in the Brazilian Midwest. The dependent variable was tobacco use, and the independent variables were sociodemographic, life history, legal status, and use of other drugs. Descriptive and bivariate analyses were performed, using prevalence ratios through the Chi-square test and Poisson regression in the multivariate analysis. Tobacco use prevalence was 86.87%. In the final model, the variables: age group, from 18-39 years (PR 1.33; 95%CI 1.10-1.61), alcohol use (PR 1.26; 95%CI 1.00-1.59), marijuana use (PR 1.16; 95%CI 1.03-1.30), and interaction between prison time and cocaine use (PR 1.05; 95%CI 1.00-1.11) remained associated with tobacco use. Tobacco use prevalence was high. The age group 18-39 years, alcohol and marijuana use and interaction between imprisonment length of 36 months or more and cocaine use were associated with tobacco use.

摘要：烟草使用是一项公共卫生议题，监狱系统内的烟草使用问题始终颇具争议。该群体的烟草使用患病率居高不下，女子监狱亦不例外。本研究旨在估算被剥夺自由女性群体的烟草使用患病率及其相关影响因素。本研究为横断面研究（Cross-sectional study），共纳入巴西中西部某监狱的259名参与者，所有受试者均完成了问卷调研。本研究的因变量为烟草使用情况，自变量涵盖社会人口学特征、生活史、法律状态及其他药物使用情况。研究采用描述性分析与双变量分析，通过卡方检验（Chi-square test）计算患病率比（prevalence ratios, PR），多因素分析则采用泊松回归（Poisson regression）。结果显示，该群体的烟草使用患病率为86.87%。最终回归模型中，以下变量与烟草使用存在显著关联：18~39岁年龄组（PR 1.33；95%置信区间[CI] 1.10~1.61）、酒精使用（PR 1.26；95%CI 1.00~1.59）、大麻使用（PR 1.16；95%CI 1.03~1.30），以及监禁时长与可卡因使用的交互作用（PR 1.05；95%CI 1.00~1.11）。综上，该群体烟草使用患病率较高，18~39岁年龄组、酒精与大麻使用情况，以及监禁时长36个月及以上与可卡因使用的交互作用均与烟草使用显著相关。
