Good-quality sleep is defined by its ability to minimize disturbances, provide adequate duration, and maintain a balanced progression through sleep stages. Sleep disturbance is a common complaint in people living with HIV/AIDS. Despite the influence of sleep disturbance on treatment adherence, quality of life, work productivity, risk of chronic illness. Studies have reported sleep disturbances among HIV/AIDS patients in sub-Saharan African countries (SSA), yielding varied results at the country level. Therefore, conducting a systematic review and meta-analysis is essential. This systematic review and meta-analysis aimed to evaluate the prevalence of poor sleep quality and identify associated factors among HIV/AIDS patients in sub-Saharan African countries. We systematically searched across various databases, including PubMed, African Journals Online, Scopus, Cochrane Library, HINARI, and Science Direct. Additionally, we conducted searches using Google and Google Scholar search engines. Microsoft Excel was used for data extraction, and the data were analysed using STAT version 17.0. We assessed heterogeneity using Cochran’s Q test and I2 test and checked for small study effects using funnel plot symmetry and Egger’s test. Pooled prevalence and associated factors were estimated using a random-effects model at a 95% confidence interval (CI) and significance level of p < 0.05. To identify factors associated with poor sleep quality among individuals living with HIV/AIDS, odds ratios (ORs) and their corresponding 95% CI were calculated. This analysis combined data from 15 separate studies involving a total sample size of 5176 participants. The pooled prevalence of poor sleep quality among HIV/AIDS patients in SSA countries was 49.32% (95% CI 41.32–56.8%). Factors significantly associated with poor sleep quality included depression (OR 2.78; 95% CI 1.21–6.40) and CD4 count < 200 cells/mm3 (AOR 3.15; 95% CI 2.41–4.15). In this study the prevalence of poor sleep quality among HIV/AIDS patients in SSA was higher and differs across the countries, ranging from 21.7 to 73.7%. The findings underscore the urgent necessity for programs aimed at improving sleep quality, particularly in addressing factors such as participant income and depression that are linked to poor sleep quality in HIV/AIDS patients.Systematic review registration: PROSPERO CRD42024517229.
