Background. Social risk factors for hypoglycemia are not well understood. Methods. Cross-sectional analysis from the DISTANCE study, a multi-language, ethnically-stratified random sample of adults in the Kaiser Permanente Northern California diabetes registry, conducted in 2005–2006 (response rate 62%). Exposures were income and educational attainment; outcome was patient report of severe hypoglycemia. To test the association, we used multivariable logistic regression to adjust for demographic and clinical factors. Results. 14,357 patients were included. Reports of severe hypoglycemia were common (11%), and higher in low-income vs. high-income (16% vs. 8.8) and low-education vs. high-education (11.9% vs. 8.9%) groups. In multivariable analysis, incomes of less than $15,000 (OR 1.51 95%CI 1.19–1.91), $15,000–$24,999 (OR 1.57 95%CI 1.27–1.94), and high school or less education (OR 1.42, 95% CI 1.24–1.63) were associated with increased hypoglycemia, similar to insulin use (OR 1.44 95%CI 1.19–1.74). Conclusions. Low income and educational attainment are important risk factors for hypoglycemia.
