Inappropriate use and increase of health care spending reinforce the need to extend our knowledge about the quality of medication use.
To describe and evaluate the profile of medication use in a representative sample of adult users of primary care services in the Unified Health System (SUS) of Minas Gerais.
Cross-sectional study, with 1,159 interviewees in 104 municipalities and 253 health care services. Data on sociodemographic characteristics, health conditions and use of medicines were collected, and these variables were stratified by age group. Univariate and multivariate analyses, using logistic regression, were conducted to identify predictors of self-medication. We set a significance level of 5% for all tests.
The prevalence of medication use was 81.8%, with an average of 2.67 medicines per user, which increased with age. The most used drugs were losartan, hydrochlorothiazide and simvastatin, which differed between age groups. Significant self-medication was observed not only in young adults but also in the elderly. The predictors of self-medication were: being a young adult, having a higher level of education, not having chronic diseases, having worse self-perception of health and not adhering to prescription drugs. Young and elderly adults showed characteristics that made them more vulnerable in relation to the rational use of medicines.
This study can contribute to improving primary care, where it identified problems related to the extent of medication use, especially among young adults and the elderly in Minas Gerais.
医疗保健支出的不当使用和增加强化了我们扩展用药质量知识的必要性。
描述和评估米纳斯吉拉斯州统一卫生系统（SUS）初级保健服务成年使用者代表性样本中的用药情况。
横断面研究，对104个市和253个医疗保健服务机构的1159名受访者进行调查。收集社会人口学特征、健康状况和用药数据，并按年龄组对这些变量进行分层。采用逻辑回归进行单变量和多变量分析，以确定自我用药的预测因素。所有检验的显著性水平设定为5%。
用药患病率为81.8%，每位使用者平均用药2.67种，且随年龄增长而增加。最常用的药物是氯沙坦、氢氯噻嗪和辛伐他汀，不同年龄组有所不同。不仅在年轻人中，而且在老年人中都观察到了显著的自我用药现象。自我用药的预测因素为：年轻成年人、教育水平较高、无慢性病、自我健康认知较差以及不遵医嘱用药。年轻人和老年人表现出在合理用药方面更容易出现问题的特征。
本研究有助于改善初级保健，它发现了与用药范围相关的问题，尤其是在米纳斯吉拉斯州的年轻人和老年人中。
