Food taboos and their perceived reasons among pregnant women in Ethiopia: a systematic review, 2022

BACKGROUND: There are foods considered as taboo across different communities in the world and in Ethiopia in particular. Although food taboos exist across all ages or physiologic states, they are predominant among pregnant women and children. Identifying such foods among pregnant women is crucial in providing focused interventions and prevents their negative consequences. Therefore, the aim of this review was to review the available evidence on food taboos and their perceived reasons among pregnant women in Ethiopia to provide comprehensive and precise evidence for decision making. METHODS: Electronic search of the literature was made from Pub-Med, Google Scholar, Google Scopus, and Medline databases using search terms set based on the PICO/PS (Population, Intervention/exposure, Comparison, and Outcome) and PS (Population and Situation) search table. The search was made from December 05, 2020 – December, 29, 2021, and updated on January, 2022. All quantitative and qualitative studies published in English were included in the review. The systematic review protocol was registered at INPLASY (Registration number: INPLASY202310078). The outcome of interest was food taboo for pregnant women and its perceived reasons. The results of the review was narrated. RESULTS: After identifying eighty two articles, thirteen were found eligible for the review. Vegetables, fruits, and fatty foods like meat, and dairy products were considered as taboo for pregnant women in different parts of Ethiopia. The reasons stated for the food taboo vary from fear of having a big baby, obstructed labour, and abortion to evil eye and physical and aesthetic deformities in the newborn. CONCLUSIONS: Though not uniform across the country, there are foods considered as taboo for pregnant women in Ethiopia due to several perceived reasons, misconceptions, and societal influences. This could increase the risk of malnutrition and could have short and long term consequences on both the mother and her growing foetus. Therefore, context specific nutritional counseling with emphasis during ante-natal care and post-natal service is important.
