Prevalence, pattern and predictors of self-medication for COVID-19 among residents in Umuahia, Abia State, Southeast Nigeria: policy and public health implications

Abstract

BackgroundCOVID-19 has led to restrictions on movements and lockdown measures, which have resulted to higher utilization of over-the-counter drugs compared to prescription-only drugs. This study determined the prevalence, pattern and predictors of self-medication for COVID-19 prevention and treatment.MethodsA cross-sectional survey was conducted between October and November 2021 among the residents of Umuahia, Abia State. The respondents were selected using a snowball sampling technique, and a self-administered semi-structured questionnaire was used to collect data on the variables via Google forms. Descriptive, bivariate and multivariate analyses were done using IBM SPSS version 26. The level of significance was set at 5%.ResultsA total of 469 respondents participated in the survey. The overall prevalence of self-medication for COVID-19 prevention and treatment was 30.3% (95%CI: 26.7–34.1). The most commonly used medication was herbal products (43.7%). This was mainly self-prepared (41.5%). The major source of information for self-medication was from family members (39.4%). The majority of the respondents reported fear of isolation (76.3%), followed by fear of stigmatization (75.7%) as the triggers of self-medication. Older age (aOR = 1.87, 95% CI: 1.11–3.13), lower educational status [No formal education (aOR = 3.78, 95% CI: 1.28–11.19)], [Primary education (aOR = 2.15, 95% CI: 1.17–3.097)] and perception to cost (aOR = 2.29; 95CI: I.24–4.24) were the predictors of self-medication.ConclusionEvery one in three residents of Umuahia, Abia State, practiced self-medication for COVID-19 prevention and treatment. Some economic and socio-demographic factors were significantly associated with self-medication. We recommend intensifying public awareness campaigns on the risk of self-medication.
