Association of Food Insecurity with Nutrition Status, Food Diversity and Anthropometric Status in in Iranian elderly: a cross-sectional study
Objective: Health and nutritional issues of the elderly are different from other age groups. The results of studies cannot be compared and concluded since these studies have different functional definitions, such as considering food quality rather than the amount of food intake and also limiting some causes of food insecurity in the analysis and the presentation of results in others. Therefore, we investigated the effects of food insecurity on food diversity, nutritional and anthropometric status in the elderly in Tehran.
Methods: This cross-sectional study was performed on 300 elderly residents in Tehran, with a mean age of 67.5±5.74. Food insecurity was evaluated using the questionnaire of Household Food Insecurity Access Scale (HFIAS). Moreover, Nutritional status and health of the elderly were assessed using the questionnaire of Mini Nutritional Assessment (MNA). Waist circumference, weight and height were measured and BMI was calculated. All statistical calculations were performed with the SPSS.
Results: The Malnourished was statistically meaningful (p<0.001) higher in severely food insecure people (62.5%). In addition, a significant inverse relationship between Household Food Insecurity Access Scale with Weight (kg) (β=-4.38, p<0.001), BMI (kg/m2) (β=-1.46, p<0.001), WC (cm2) (β=-3.37, p= 0.002), and Dietary Diversity Score (β=-0.738, p<0.001) was observed. Moreover, we found a significant relation between Household Food Insecurity Access Scale and Mini Nutritional Assessment score (β=0.486, p<0.001). Participants in food insecure group had more risk of Malnourished (OR 16.45; 95% CI 8.55, 31.66) and poor Dietary Diversity (OR 7.42; 95% CI 2.87, 19.16) compared with food secure group.
Conclusion: After adjusted for possible confounding factors, we found that food insecurity was associated with MNA score. We also found an inverse association between food insecurity, socioeconomic statues, anthropometric measurements and DDS.
