Determinants associated with low dietary diversity among migrants to Morocco: a cross sectional study

Abstract

Low dietary diversity (LDD) is prevalent among vulnerable populations, posing a morbidity risk. Few studies have been conducted on the dietary diversity of migrants. The objectives of this study are to determine the prevalence of LDD among migrants in Morocco and the risk factors associated with it. In the Oriental region, we conducted a cross-sectional study with migrants between November and December 2021. The sampling method used was convenience sampling. A face-to-face, structured questionnaire was used to collect sociodemographic, behavioral, and clinical data. We calculated a dietary diversity score based on a 24-h food recall and assessed food intake. The risk factors associated with LDD were identified using multivariate logistic regression. A total of 445 migrants was enrolled. The prevalence of LDD was 31.7%. Risk factors associated with LDD were: being homeless (adjusted Odds Ratio (AOR) of 6.32; CI% [3.55-11.25]), a lack of social support (AOR of 2.30; CI% [1.33-03.98]), and low monthly income (AOR of 8.21; CI% [3.39-19.85]). Public policies must focus on social and environmental determinants. Nutrition training programs should be set up for the migrant population.
