People with type 2 diabetes who face housing insecurity have more difficulties controlling blood sugar levels. In a new study from California, adults with type 2 diabetes who had at least one address change in a year showed much higher rates of HbA1c (over 9%) compared to people with no address change. An HbA1c above 9% is associated with a much higher risk of serious long-term health complications due to diabetes. The researchers concluded that an address change may be an early warning sign of housing insecurity or stress that could be used to activate screening or other interventions. Rates of emergency department usage were also higher for those with recent address changes. Additionally, flu shots were less common in those who moved at least once than those who had not moved. In this study, about 80% of the individuals were over age 50 (average age was 62), including 30% Black, 23% Asian, 22% White, and 21% Hispanic participants. The researchers defined “housing insecurity” based on at least one address change in the patients’ electronic medical record. Although an address change may not signal housing insecurity, it could signal stress related to moving.
