Food Insecurity and Diabetes Insulin Adherence Among Older Adults

Older adults in the United States continue to be impacted by food insecurity. Diabetes is on the rise in older adults and insulin therapy is often recommended as treatment. However, less is known about the relationship between food insecurity and insulin adherence among older adults. The current study utilized secondary data analysis methods to examine the 2021 National Health Interview Survey to explore the relationship between food insecurity and insulin adherence among adults aged 55 and older who are living with diabetes. Results of multivariable logistic regression suggest that participants experiencing food insecurity were more likely to take less insulin than needed and delay buying insulin in the past 12 months compared to participants who were food secure. Homeownership was inversely associated with taking less insulin than needed. Higher income-to-poverty ratio was also inversely associated with skipping insulin doses, taking less insulin than needed, and delaying the purchase of insulin. Our results showed that other racialized/ethnic groups (i.e., American Indian, Alaskan Native, Asian, biracial, and multiracial persons) compared to White were less likely to skip an insulin dose and take less insulin than needed. Suggesting food insecurity should be considered when insulin therapy is recommended for older adults with diabetes.
