Food taboo practices and associated factors among pregnant women in Ethiopia: a systematic review and meta-analysis

Abstract

Food taboos have a negative impact on pregnant women and their fetuses by preventing them from consuming vital foods. Previous research found that pregnant women avoided certain foods during their pregnancy for a variety of reasons. This review aimed to determine the pooled prevalence of food taboo practices and associated factors in Ethiopia. In compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, we searched the literature using PubMed/MEDLINE, AJOL (African Journal Online), HINARI, Science Direct, Google Scholar, and Google electronic databases. The random-effects model was used to estimate the pooled prevalence of food taboo and its determinants at a 95% confidence interval with their respective odds ratios. The pooled food taboo practice among Ethiopian pregnant women was 34.22% (95% CI 25.47–42.96), and after adjustment for publication bias with the trim-and-fill analysis, the pooled food taboo practice of pregnant women was changed to 21.31% (95% CI: 10.85–31.67%). Having less than a secondary education level (OR = 3.57; 95% CI 1.43–8.89), having no ANC follow-up (OR = 4.35; 95% CI 1.12–16.94), and being a rural resident (OR = 3.08; 95% CI 1.14–8.28) were the significant factors. Dairy products, some fruits, green leafy vegetables, meat, and honey are among the taboo foods. The most frequently stated reasons for this taboo practice were: fear of producing a big fetus, which is difficult during delivery; attachment to the fetus's body or head; and fear of fetal abnormality.
