Objective To evaluate the pooled prevalence and identify risk factors of congenital anomalies among neonates in Africa.Methods The pooled birth prevalence of congenital anomalies was the first outcome of this review, and the pooled measure of association between congenital anomalies and related risk factors in Africa was the second. We conducted a thorough search of the databases PubMed/ Medline, PubMed Central, Hinary, Google, Cochrane Library, African Journals Online, Web of Science and Google Scholar up to 31 January 2023. The JBI appraisal checklist was used to evaluate the studies. STATA V.17 was used for the analysis. The I2 test and Eggers and Beggs tests were used to measure study heterogeneity and publication bias respectively. The pooled prevalence of congenital anomalies was calculated using DerSimonian and Laird random-effect model. Subgroup analysis, sensitivity analysis and meta-regression were also performed.Result This systematic review and meta-analysis includes 32 studies with a total of 626 983 participants. The pooled prevalence of congenital anomalies was 23.5 (95% CI 20 to 26.9) per 1000 newborns. Not taking folic acid (pooled OR=2.67; 95% CI (1.42 to 5.00)), history of maternal illness (pooled OR=2.44, 95% CI (1.2 to 4.94)), history of drug use (pooled OR=2.74, 95% CI (1.29 to 5.81)), maternal age (>35 years.) (Pooled OR=1.97, 95% CI (1.15 to 3.37)), drinking alcohol (pooled OR=3.15, 95% CI (1.4 to 7.04)), kchat chewing (pooled OR=3.34, 5% CI (1.68 to 6.65)) and urban residence (pooled OR=0.58, 95% CI (0.36 to 0.95)) were had significant association with congenital anomalies.Conclusion The pooled prevalence of congenital abnormalities in Africa was found to be substantial, with significant regional variation. Appropriate folate supplementation during pregnancy, proper management of maternal sickness, proper antenatal care, referring healthcare personnel before using drugs, avoiding alcohol intake and kchat chewing are all important in lowering the occurrence of congenital abnormalities among newborns in Africa.

Objective Undernutrition contributes to decreased physical and cognitive functional status, higher healthcare consumption, premature institutionalisation and increased mortality. So, the objective of this study was to determine the pooled prevalence and factors associated with undernutrition among older adults in Ethiopia.Design Systematic review and meta-analysis was used. Articles that presented original data on undernutrition using body mass index (BMI) were included. We made an inclusive literature search from PubMed, Medline and Google Scholar. The I2 test was used to examine the heterogeneity of the studies considered in this meta-analysis. Stata software V.14 and METANDI command were used.Setting Studies conducted in Ethiopia were included.Participants Eight independent studies were eligible and enrolled for final analysis.Outcome Prevalence and determinants of undernutrition. A selection of publications, data extraction and reported results for the review was designed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.Results A total of eight unique studies were enrolled for final analysis. The pooled prevalence of undernutrition was 20.53% (95% CI 17.39% to 23.67%). The study revealed that males had lesser odds of being undernutrition with AOR 0.17 (95% CI 0.15 to 0.20). Older adults in the age range of 65–74 years were less likely to be undernourished as compared with those whose age was above 85 years with Adjusted Odds Ratio (AOR) 022 (95% CI 0.22 to 0.25). Older adults who were depressed had higher odds of undernutrition as compared with their counterparts with AOR 1.27 (95% CI 1.19 to 1.37). However, older adults from households with poor wealth indexes were two times more likely to be undernourished as compared with those who were from rich households.Conclusion The burden of undernutrition in Ethiopia is significant. The limitation of the current study was that all included studies were observational, mainly cross-sectional.
