Our study aimed to describe the prevalence of self-medication among the Paris adult population and to identify the factors associated with self-medication.
This cross-sectional study was based on data collected from the SIRS cohort (a French acronym for "Health, inequalities and social ruptures") in 2005 in the Paris metropolitan area using a face-to-face administration questionnaire among a representative sample of 3,023 French-speaking adults. Structural equation models were used to investigate the factors associated with self-medication in the overall population and according to income.
The prevalence of self-medication in the past four weeks was 53.5% in the Paris metropolitan area. Seven factors were directly associated with self-medication in the structural equation model. Self-medication was found more common among women, young people, in active employment or student, with a high income, but also among people with a health information seeking behavior, with a high daily mobility, and/or with a history of unmet healthcare needs due to economic reasons. When looking at these coefficients according to income, the association between self-medication and daily mobility appeared stronger in the bottom quartile of income whereas it was no longer significant in the rest of the survey population.
Self-medication is a frequent practice in the Paris metropolitan area. This study confirms the role of some factors found to be associated with self-medication in the literature such as age or gender and draws attention to other factors rarely explored such as daily mobility, especially among people with a low income, or health information seeking behavior.
本研究旨在描述巴黎成年人群体的自我用药流行情况，并确定与自我用药相关的因素。
这是一项横断面研究，基于 2005 年在巴黎大都市区进行的 SIRS 队列（法语缩写为“健康、不平等和社会破裂”）的数据，使用面对面管理问卷对 3023 名讲法语的成年人进行了代表性抽样。结构方程模型用于调查整个人群和按收入分层与自我用药相关的因素。
在过去四周内，巴黎大都市区的自我用药率为 53.5%。在结构方程模型中，有七个因素与自我用药直接相关。自我用药在女性、年轻人、在职或学生、高收入者中更为常见，但在有健康信息寻求行为、日常活动度高、或因经济原因未满足医疗保健需求的人群中也更为常见。当根据收入来看这些系数时，自我用药与日常活动度之间的关联在收入最低的四分之一人群中更为强烈，而在其余调查人群中则不再显著。
自我用药在巴黎大都市区是一种常见做法。本研究证实了一些与文献中发现的自我用药相关的因素的作用，如年龄或性别，并提请注意其他很少被探索的因素，如日常活动度，特别是在收入较低的人群中，或健康信息寻求行为。
