People with diabetes who had a poor-quality diet and food insecurity were significantly more likely to have poor glycemic and cholesterol control than were those with a healthier diet and food security, based on data from a national study of more than 2,000 individuals.
The American Diabetes Association recommends a high-quality diet for people with diabetes (PWD) to achieve treatment goals; however, roughly 18% of PWD in the United States are food insecure and/or have a poor-quality diet, Sarah S. Casagrande, PhD, of DLH Corporation, Silver Spring, Md., and colleagues wrote in a poster presented at the annual scientific sessions of the ADA in New Orleans.
To examine the impact of food insecurity and diet quality on diabetes and lipid management, the researchers reviewed data from 2,075 adults with self-reported diabetes who completed the National Health and Nutrition Examination Surveys between 2013 and 2018.
Diet quality was divided into quartiles based on the 2015 Healthy Eating Index. Food insecurity was assessed using a standard 10-item questionnaire including questions about running out of food and not being able to afford more, reducing meal sizes, eating less or not at all, and going hungry because of lack of money for food.
The logistic regression analysis controlled for factors including sociodemographics, health care use, smoking, diabetes medications, blood pressure medication use, cholesterol medication use, and body mass index.
Overall, 17.6% of the participants were food insecure and had a low-quality diet, 14.2% were food insecure with a high-quality diet, 33.1% were food secure with a low-quality diet, and 35.2% were food secure with a high-quality diet.
PWD in the food insecure/low-quality diet group were significantly more likely to be younger, non-Hispanic black or Hispanic, and uninsured compared to those in the food secure/high-quality diet group (P < .001 for all).
When the researchers examined glycemic control, they found that PWD in the food insecurity/low-quality diet groups were significantly more likely than were those with food security/high-quality diets to have hemoglobin A1c of at least 7.0% (adjusted odds ratio, 1.85), A1c of at least 8.0% (aOR, 1.79), low HDL cholesterol (aOR, 1.69), and high triglycerides (aOR, 3.26).
PWD with food insecurity but a high-quality diet also were significantly more likely than were those with food security and a high quality diet to have A1c of at least 7.0% (aOR, 1.69), A1c of at least 8.0% (aOR, 1.83), and high triglycerides (aOR, 2.44). PWD with food security but a low-quality diet were significantly more likely than was the food security/high-quality diet group to have A1c of at least 7% (aOR, 1.55).
The study findings were limited by several factors including the cross-sectional design, reliance on self-reports, and inability to distinguish between type 1 and type 2 diabetes, the researchers wrote.
However, the results were strengthened by the large, nationally representative sample and the inclusion of multiple clinical outcomes in the patient assessment, they said.
The results suggest that food insecurity had a significant impact on both glycemic control and cholesterol management independent of diet quality, the researchers noted. Based on these findings, health care providers treating PWD may wish to assess their patients’ food security status, and “interventions could address disparities in food security,” they concluded.
