TUESDAY, July 9, 2019 (HealthDay News) — Household food insecurity (HFI) is associated with insulin resistance among Latinos with type 2 diabetes, according to a study published in the June issue of the Journal of Nutrition<\/i>.<\/p>\n
Angela Bermudez-Millan, Ph.D., M.P.H., from the University of Connecticut in Farmington, and colleagues measured HFI using the six-item U.S. Household Food Security Survey module, while fasting plasma blood glucose and serum insulin were used to measure insulin resistance among 121 patients with type 2 diabetes (85.8 percent Puerto Rican; mean age, 60.7 years; 74 percent female).<\/p>\n
The researchers found that just over two-thirds of participants (68 percent) were classified as food-insecure. Food-insecure individuals had a significantly higher insulin resistance, insulin, glucose, high-sensitivity C-reactive protein (hsCRP), cortisol, and total cholesterol compared with food-secure individuals. For lipids, metanephrine, normetanephrine, or hemoglobin A1c, there were no differences between the groups. There was a significant direct effect of HFI on hsCRP and on cortisol in a mediation model. Additionally, there was a direct effect of cortisol, hsCRP, and HFI on insulin resistance. However, the total combined indirect effect of HFI through cortisol and hsCRP partially mediated the association.<\/p>\n
“Interventions to ameliorate HFI and mitigate its effects on inflammation, stress, and insulin resistance are warranted,” the authors write.<\/p>\n
