Association of Household Food Insecurity with Stunting and Underweight Among Iranian Children Aged 2 - 5 Years old

Background: Although previous literature has assessed the association of household food insecurity with nutritional outcomes among children, the findings are inconsistent across different study populations. Objectives: We aimed to evaluate the association of household food insecurity with nutritional outcomes among children residing in Khalkhal city, Iran. Methods: The present cross-sectional study was conducted on 300 Iranian children aged 2 - 5 years who visited urban and rural health care centers between November 2021 and March 2022. Subjects were included in the survey using multi-stage cluster sampling. Household food security status was assessed using the United States Department of Agriculture (USDA) 18-item food security questionnaire. Odds ratios (95% confidence interval) for stunting according to the food insecurity score were estimated using multivariable logistic regression in three models. Results: In the present study, 39% of participants had food security, while the prevalence of food insecurity without hunger, food insecurity with moderate hunger, and food insecurity with severe hunger were 22.3%, 23%, and 15.7%, respectively. In all models, both categorized and continuous food insecurity scores correlated negatively with weight (P for all 0.001). Food insecurity did not predict the risk of stunting in all subjects before and after adjustment (Model 1: OR (CI) = 1.008 (0.96-1.05), P = 0.72; Model 2: OR (CI) = 1.01 (0.96 - 1.05), P = 0.65; Model 3: OR (CI) = 0.98 (0.92-1.04), P = 0.53). Conclusions: In the current study, we found that Iranian families with the lowest income had the highest food insecurity scores. Household food insecurity was negatively correlated with weight status among children aged 2 - 5 years.
