RESUMEN
Introduction: The coronavirus disease 2019 (COVID-19) pandemic has triggered a rise in the global phenomenon of self-medication. The use of medicines with unsubstantiated claims of benefit for the prevention and/or treatment of infected people has been widely adopted. Objective: To determine the factors associated with the use of medicines and self-medication by Latin American populations during the COVID-19 pandemic. Methods: This analytical cross-sectional study was conducted via an analysis of secondary data collected from 8777 responses from 12 Latin American countries obtained from a survey on the use of medicines and self-medication during the pandemic. Results: Respondents who reported using Paracetamol, Ibuprofen, or antibiotics (ABx) disclosed this as self-medication in 26.9%, 16.6%, and 9.7% of cases respectively. In our multivariate analysis, significant associations were found between: self-medication by individual choice and the use of Hydroxychloroquine, ABx, or non-steroidal anti-inflammatory drugs (NSAIDs) (p = 0.026, = 0.003, and <0.001 respectively); self-medication on the recommendation of a family member, with ABx, Paracetamol, Ibuprofen, or other NSAIDs (p <0.001, <0.001, <0.001, and <0.001 respectively); and self-medication on the recommendation of another person, with Chloroquine, Hydroxychloroquine, Azithromycin, Penicillin, other ABx, Warfarin, Ivermectin, Paracetamol, Ibuprofen, or other NSAIDs (p <0.001, <0.001, <0.001, = 0.001, <0.001, <0.001, = 0.004, <0.001, <0.001, and <0.001 respectively). Conclusion: There was a significantly high prevalence of self-medication in our Latin American study population, including the use of medicines not recommended for COVID-19 treatment and/or prevention. The implementation of public health measures aimed at combating the worrying COVID-19 infodemic is essential to prevent this ongoing issue and its associated negative impacts on both current public health and future medication efficacy. This is especially important in the case of ABx due to the threat of a future antimicrobial resistance pandemic.
RESUMEN
Introduction and objective: Sci-Hub is a website that allows users to download full-text versions of millions of scientific articles for free. The objective of this study was to evaluate the association between the use of Sci-Hub and consultation of scientific journals by medical students from six Latin American countries. Methods: We conducted a secondary analysis of data from a 2017 cross-sectional study of medical students from six Latin American countries (Argentina, Bolivia, Chile, Colombia, Paraguay, and Peru). Consultation of scientific journals was considered as the dependent variable, while the independent variable was the use of Sci-Hub. Responses were categorized as: "do not know"; "did not use it"; "used it at least once a week"; "used it more than once a week"; and "used it every day of the month". In simple and multiple regression analyses, multivariate random-effects models were used to estimate prevalence ratios (PR), with 95% confident intervals (CI). Results: Of the 6632 participants, 38.2% consulted scientific journals and 10.3% used Sci-Hub once a week. Using Sci-Hub at least once a week was associated with a 20% increase in the prevalence of consulting scientific journals (PR: 1.20, 95% CI: 1.10-1.31, p < 0.001). The variables positively associated with Sci-Hub use included being in the sixth year of medical school (PR: 2.34), affiliation to more than one academic research group (PR: 1.81), being a medical student in Colombia (PR: 1.63), intermediate (PR: 1.16) and advanced levels of English (PR: 1.23), and daily use of PubMed (PR: 1.66), SciELO (PR: 1.87), and/or SCOPUS (PR: 1.58). Conclusion: Amongst medical students surveyed from the above six Latin American countries, the use of Sci-Hub at least once a week was significantly associated with the self-reported prevalence of consulting scientific journals.
