Dietary diversity and its associated factors among adolescent girls in Ethiopia: a systematic review and meta-analysis

Abstract

Background Even though fragmented and inconsistent findings have been reported in Ethiopia, adolescence is a period of rapid growth following infancy and is severely affected by micronutrient deficiencies, food insecurity, and poor-quality diets. Therefore, the aim of this meta-analysis was to estimate the pooled prevalence of dietary diversity and its associated factors among adolescent girls in Ethiopia. Methods International databases such as EMBASE, Hinari, Scopus, PubMed, Google Scholar, and direct Google searches were systematically used to search for articles and reports. The Newcastle-Ottawa Scale, modified as appropriate, was used for cross-sectional studies to assess the quality of the included articles and reports. A Microsoft Excel sheet was used for data extraction and then exported into STATA version 17 for further analysis. The pooled prevalence of dietary diversity was estimated using a random effects meta-analysis approach. Egger’s and Begg’s tests were employed to evaluate publication bias. Results The pooled prevalence of minimum dietary diversity among adolescent girls in Ethiopia was 43% (95% CI: 30, 56) with significant heterogeneity (I 2 = 99.2%, p = 0.00). Urban residence (OR: 2.46), mother being a government employee (OR: 2.31), attending a private school (OR: 6.24), adolescent having formal maternal education (OR: 4.49), adolescent having formal paternal education (OR: 3.26), father being a government employee (OR: 3.50), father being a merchant employee (OR: 2.51), middle family wealth index (OR: 1.76), household food security (OR: 3.96), receiving nutrition counseling (OR: 2.46), and higher meal frequency (OR: 7.35) were significantly associated with minimum dietary diversity. Conclusion The pooled prevalence of dietary diversity among adolescent girls was low. Factors significantly associated with achieving minimum dietary diversity included urban residence, higher parental education and employment in government, private school attendance, household wealth, food security, receiving nutrition counseling, and higher meal frequency. These findings emphasize the need to improve dietary diversity among rural adolescent girls and food insecure households. Establishing nutrition counseling services could enhance understanding and skills related to a varied diet.
