ABSTRACT

Background

The aim of this study was to investigate the prevalence of antibiotics use and self-medication among adults living in Manaus, Amazonas in 2015 and 2019.

Research design and methods

Analysis of two cross-sectional studies conducted in Manaus in 2015 and 2019. Adults aged ≥18 years were interviewed at home following a three-phase probabilistic sampling (census tracts, household, and individual). Primary outcome was the use of antibiotics in the previous 15 days. Poisson regression with robust variance was employed to calculate the prevalence ratios (PR) of antibiotics use adjusted by independent variables.

Results

The prevalence of antibiotics use in the previous fortnight was 3.7% (95%CI 3.1–4.4%; n=3,479) in 2015 and 8.0% (95%CI 6.7–9.3%; n=2,321) in 2019. Self-medication increased from 19.2% (95%CI 12.4–26.0%; n=130) in 2015 to 30.7% (95%CI 22.5–38.8%; n=187) in 2019. Beta-lactams were the most used (252/317) and self-medicated (60/317) antibiotics in both surveys. Use of antibiotics was higher in 2019 (PR=2.05; 95%CI 1.60–2.64) compared to 2015 and among women (PR=1.66; 95%CI 1.16–2.39) compared to men.

Conclusions

Antibiotics use and self-medication in Manaus increased from 2015 to 2019. Enforcement of health regulation is needed to improve compliance and minimize potential risks.

巴西亚马逊地区成年人中抗生素的使用和自我用药:2015年和2019年两个横断面研究的小组。

摘要

背景

这项研究的目的是调查2015年和2019年生活在亚马逊州马瑙斯市的成年人中抗生素使用和自我用药的普遍性。

研究设计与方法

分析了2015年和2019年在马瑙斯(Manaus)进行的两项横断面研究。经过三个阶段的概率抽样(人口普查区,家庭和个人),在家中采访了年龄≥18岁的成年人。主要结局是在过去15天内使用了抗生素。采用具有强方差的Poisson回归来计算通过独立变量调整的抗生素使用率(PR)。

结果

前两周使用抗生素的比例在2015年为3.7%(95%CI 3.1–4.4%; n = 3,479),在2019年为8.0%(95%CI 6.7–9.3%; n = 2,321)。自我用药增加从2015年的19.2%(95%CI 12.4–26.0%; n = 130)增至2019年的30.7%(95%CI 22.5–38.8%; n = 187)。β-内酰胺类使用最多(252/317)和两项调查中均使用自用(60/317)抗生素。与2015年相比,2019年的抗生素使用率更高(PR = 2.05; 95%CI 1.60-2.64),女性的使用率更高(PR = 1.66; 95%CI 1.16-2.39)。

结论

从2015年到2019年,马瑙斯使用抗生素和进行自我药物治疗的人数有所增加。需要加强健康监管,以提高依从性并将潜在风险降至最低。
