The association of food insecurity and cardiometabolic risk factors was independent of body mass index in Iranian women

Abstract

Background Investigations on food insecurity have shown that food insecurity is inversely associated with health. We examined the association of food insecurity and cardiometabolic risk factors in women living in Shiraz, Iran. Methods The cross-sectional study was performed on 190 females. Food insecurity was assessed by Household Food Insecurity Access Scale. Cardiometabolic risk factors including anthropometric characteristics, blood pressure, and serum glucose and lipids were measured. Metabolic syndrome score was calculated according to the criteria described for Iranian adults. The association of food insecurity and cardiometabolic risk factors was assessed by linear regression. Results The prevalence of food security, and mild, moderate, and severe food insecurity was 42.6%, 40.5%, 15.8%, and 1.1%, respectively. Cardiometabolic risk factors worsened with increasing severity of food insecurity. Among the risk factors, body mass index (BMI) had the strongest association with food insecurity. After controlling demographic factors and BMI, fasting blood glucose, triglycerides, total, LDL, and HDL cholesterols, and metabolic syndrome score still showed significant associations with food insecurity (P < 0.01) but systolic and diastolic blood pressure were no longer associated with food insecurity after adjustment for BMI. Conclusion Overall, although BMI was strongly associated with food insecurity, cardiometabolic risk factors including blood glucose, triglycerides, total, HDL, and LDL cholesterols, and metabolic syndrome score were associated with food insecurity independent of BMI, suggesting that other factors such as lifestyle and diet may have contributed to the exacerbated cardiometabolic risk in food insecure participants of this study. Future studies need to clarify underlying factors in the association of food insecurity and cardiometabolic risk factors.

“…The association between food insecurity and cardiometabolic risk factors was explored in a study conducted in Iran (Hashemzadeh et al, 2022). The study found that cardiometabolic risk factors, such as blood glucose, triglycerides, total, HDL, and LDL cholesterols, and metabolic syndrome score, were associated with food insecurity independent of body mass index (BMI) (Hashemzadeh et al, 2022). This suggests that factors beyond BMI, such as lifestyle and diet, may contribute to the increased cardiometabolic risk in food-insecure individuals.…”
