The objective of the study was to estimate the prevalence of generics and their associated factors in a population of adults aged 20 to 59 years. The sample consisted of 374 individuals from the catchment area of a Family Health Unit in Ponta Grossa, PR, Brazil. Data were collected in home interviews. Study variables were divided into 3 groups: sociodemographic, health status and the use of health services. The chi-square test was used for statistical analysis. The prevalence of generics was 9.9%. Of those interviewed, 96.5% claimed to know about generic drugs, 64.3% believed they had the same quality as brand-name drugs and 88.9% reported they were cheaper. The most commonly-used groups of drugs were those for the nervous system and those for the cardiovascular system. After univariate analysis, the following factors were found to be statistically significant: economic status, employment status, health insurance, presence of chronic disease, medical consultation in the previous three months and hospitalization within the previous 12 months. The low prevalence of the use of generic drugs emphasizes the fact that stronger policies are needed to make generics available to the public, especially through the Family Health Strategy, since it is the studied population's principal form of access to these medications.
该研究的目的是估计20至59岁成年人群中通用药物的使用率及其相关因素。样本包括来自巴西巴拉那州蓬塔格罗萨市一家家庭健康中心服务区域的374名个体。数据通过上门访谈收集。研究变量分为三组：社会人口统计学变量、健康状况和医疗服务使用情况。采用卡方检验进行统计分析。通用药物的使用率为9.9%。在接受访谈的人群中，96.5%声称了解通用药物，64.3%认为其质量与品牌药相同，88.9%表示通用药物更便宜。最常用的药物类别是神经系统用药和心血管系统用药。单因素分析后发现，以下因素具有统计学意义：经济状况、就业状况、医疗保险、慢性病的存在、过去三个月内的医疗咨询以及过去12个月内的住院情况。通用药物的低使用率凸显了这样一个事实，即需要出台更有力的政策，以使公众能够获得通用药物，特别是通过家庭健康战略，因为这是研究人群获取这些药物的主要途径。
