Menstrual hygiene practice and associated factors among adolescent girls in sub-Saharan Africa: a systematic review and meta-analysis

BACKGROUND: Menstrual hygiene has not received adequate attention in Sub-Saharan Africa, and there is a lack of regional representative data. Therefore, this study aimed to estimate the pooled prevalence of good menstrual hygiene practices and associated factors among adolescent girls in sub-Saharan Africa. METHODS: In this study, the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used to develop the review manuscript. Online electronic databases, such as PubMed/Medline, Google Scholar, and CINAHL, were searched to retrieve available studies. The database search was conducted from January 1 to May 17, 2022. The selection, quality assessment, and data extraction of the studies were performed. Quality assessment of the studies was performed using the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. Subgroup analysis and meta-regression were performed based on country, study area, and sample size. Publication bias was examined by funnel plots and Egger’s test. The statistical analysis was conducted using STATA version 14 software and RevMan software, and statistical significance was declared at a p value of less than 0.05. PROTOCOL REGISTRATION NUMBER: CRD42020165628. RESULTS: A total of 229 studies were retrieved, and 14 studies were included in the final meta-analysis. The pooled prevalence of good menstrual hygiene practices was 45% (95% CI, (37, 53). Adolescents from urban residences (OR = 3.03, 95% CI (2.3, 3.97)), able to afford menstrual sanitary products (OR = 2.17, 95% CI (1.42, 3.3)), and from educated mothers (OR = 2.33, 95% CI (1.32, 4.12)) were associated with increased odds of good menstrual hygiene practice. CONCLUSION: The pooled prevalence of menstrual hygiene practices was low compared to the SDG 6.2 target by 2030. “Achieve access to adequate and equitable sanitation and hygiene for all, paying special attention to the needs of women and girls and those in vulnerable situations”. Therefore, improving the accessibility of a safe water supply, hygiene, sanitation facilities and affordability of menstrual products and promoting maternal education are mandatory and should be part of government-level public health policy to prevent related health issues, loss of economic output and education opportunities.
