Undernutrition among khat-chewer and non-chewer lactating women in Chiro district, eastern Ethiopia: Comparative cross-sectional study

Objectives: This study aims to assess the prevalence of undernutrition and factors associated with it among khat-chewer and non-chewer lactating women at Chiro district, west Hararghe zone, eastern Ethiopia. Methods: A community-based comparative cross-sectional study was conducted among 446 (223 khat chewers and 223 non-chewers) randomly selected lactating women who have children aged 6 and 23 months. Data were collected through face-to-face interviews using structured questionnaires followed by weight and height measurements to calculate and categorize nutritional status based on body mass index (kg/m2). Data were entered into EpiData version 3.1 and analyzed using STATA version 14.2. A binary logistic regression model was fitted to check the association between independent variables and undernutrition. The level of statistical significance was declared at a p-value less than 0.05. Results: The overall prevalence of undernutrition among lactating women was 30.7% (95% confidence interval = 26.6, 35.2). Undernutrition was significantly higher among khat chewers, 39.0% (95% confidence interval = 32.8, 45.6) than non-chewers, 22.4% (95% confidence interval = 17.4, 28.4), (χ2 (degree of freedom) = 14.4231, p
