Inadequate dietary diversity practices and associated factors among pregnant adolescents in the West Arsi Zone, Central Ethiopia: a community-based cross-sectional study

Abstract

AbstractThe aftermath of dietary modifications made during pregnancy has the most substantial effects on nutritional status and birth results, despite the important influence of nutritional reserves. Numerous studies have been conducted on dietary practices and their determinants among pregnant women; however, there is a gap in evidence among pregnant adolescents. Therefore, this study sought to close this gap by examining dietary practices and associated factors among pregnant adolescents in the West Arsi Zone, Central Ethiopia. This community-based cross-sectional study was conducted among 459 pregnant adolescents between February and March 2023. Cluster sampling was used for selecting pregnant adolescents. Structured questionnaires were used for data collection. The data were entered into the Kobo toolbox and exported to SPSS version 25 software for analysis. Dietary diversity was assessed using the 24-h dietary recall method. Binary and multivariable logistic regression analyses were used to identify independent predictors of dietary practices. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to identify the factors associated with the outcome variables. A p value ≤ 0.05 indicated statistical significance. The prevalence of inadequate dietary practices among the pregnant adolescents was 78.4% (95% CI 74.3%, 82.8%), and a level of nutritional knowledge [AOR = 2.4, 95% CI (1.82–4.74]; an unfavorable attitude toward dietary diversity [AOR = 4.3, 95% CI 2.9–5.83]; a food insecurity status [AOR = 8.7, 95% CI 2.37–10.24]; and a low perceived severity of poor dietary practices [AOR = 4.7, 95% CI 3.26–5.47]. These factors were significantly associated with inadequate dietary practices among pregnant adolescents. The most frequently consumed foods were starchy foods (81.3%) and pulses (79%), and the least consumed foods were meat (2.8%) and fruits (3.48%). The magnitude of inadequate dietary practices was high, and it was significantly associated with educational, behavioral, and economic status. Nutritional interventions focused on communicating nutritional behavioral changes and strengthening sustainable income-generating strategies are recommended to improve the dietary practices of pregnant adolescents.
