Table1_Substance Use Among Residents of Homeless Shelters During the COVID-19 Pandemic: Findings From France.pdf

Objectives: To record the prevalence and risk factors of substance use amongst homeless persons during the COVID-19 pandemic.
Methods: The ECHO study consisted in two independent cross-sectional waves of data collection in the regions of Paris, Lyon, and Strasbourg during the Spring of 2020 (n = 530) and 2021 (n = 319). Factors associated with substance use were explored using generalised logistic regression models.
Results: The most prevalent substance used was tobacco (38%–43%), followed by alcohol (26%–34%). The use of both substances positively associated with each other, although risk factors varied depending on the substance. The only factors consistently associated with alcohol and tobacco use were being male, exposure to theft/assault and participants’ region of origin. Whilst the rate of tobacco use was relatively stable between Spring 2020 and 2021, alcohol use was more common in 2021.
Conclusion: These findings highlight a high prevalence of substance use amongst homeless persons. People experiencing homelessness face specific challenges in the context of the pandemic, alongside greater vulnerability to illness and low healthcare access, therefore the need to improve prevention and support services for substance abuse within this population is vital.

研究目的：记录新冠疫情期间无家可归人群的物质使用（substance use）流行率及其危险因素。
研究方法：本ECHO研究（ECHO study）于2020年春季（样本量n=530）与2021年春季（样本量n=319），在巴黎、里昂及斯特拉斯堡地区开展了两次独立的横断面数据收集波次。本研究采用广义逻辑回归模型，对与物质使用相关的影响因素进行探索分析。
研究结果：本次调研中最普遍的物质使用类型为烟草（占比38%~43%），其次为酒精（占比26%~34%）。两类物质的使用行为呈显著正相关，但不同物质对应的危险因素存在差异。仅男性身份、遭遇盗窃/袭击经历以及受访者的原籍地区，是与酒精及烟草使用均显著相关的共同危险因素。尽管烟草使用比例在2020年与2021年春季相对稳定，但2021年的酒精使用比例更高。
研究结论：本研究结果凸显了无家可归人群中物质使用的高流行现状。无家可归者在疫情背景下面临诸多特殊挑战，同时罹患疾病的风险更高、医疗可及性较差，因此针对该人群完善物质滥用的预防与支持服务极为必要。
