The burdens, associated factors, and reasons for traditional uvulectomy in Ethiopia: A systematic review and meta-analysis

Introduction: Traditional uvulectomy is a harmful procedure in which the entire or a portion of the uvula is removed by traditional practitioners. It causes complications like septicemia, transmission of infectious diseases, anemia, excessive bleeding, infection, tetanus, meningitis, and death. A summary of national data was lacking, thus, the study aimed to determine the pooled national burden and determinants of traditional uvulectomy in Ethiopia.

Methods: Studies were retrieved from PubMed, EMBASE, CINHAL (EBSCO), Google Scholar, Web of Sciences, MEDLINE, Cochrane Library, SCOPUS, and Google databases. Finally, 19 studies were included. The methodological quality of the included studies was assessed using the JBI checklist. Data synthesis and statistical analysis were conducted using STATA Version 17 software. Heterogeneity and publication bias were assessed. Forest plots were used to present the pooled and summarized with random-effects meta-analysis models.

Results: Totally 19 articles with 23,559 study participants were included in this systematic review and meta-analysis. The overall pooled prevalence of uvulectomy in Ethiopia was 44 % (95 % CI: 31%-57 %). The highest prevalence was observed among studies conducted in the Tigray region (63 % (95 % CI: 34%-94 %), between the year 2011-2014 (58 % (95 % CI: 29%-87 %)) and, community setting (57 % (95 % CI: 36%-78 %). Mothers' educational status (AOR: 1.66, 95 % CI: 1.31-2.01) and residence (AOR: 1.70, 95 % CI: 1.16-2.23) were found to be significantly associated with traditional uvulectomy in Ethiopia. Frequently cited reasons for traditional uvulectomy were to prevent swelling, pus, and rupture of the uvula, for better care, prevention of sore throats and coughs, religion, and culture.

Conclusion: The pooled result revealed that almost half of children are still subjected to traditional uvulectomy in Ethiopia. There is a need to intensify awareness creation campaigns against the practice by giving special attention to rural residents and uneducated ones.
