965-P: Factors Associated with Poor Glycemic Control in Persons with Type 2 Diabetes and Employer-Based Health Care Coverage

Abstract

Lack of healthcare insurance is an important factor for poor glycemic control in persons with diabetes. However, a large proportion of insured people also have inadequate glycemic control. This study was conducted to assess factors associated with poor glycemic control in persons with type 2 diabetics (T2D) who received full healthcare coverage through their employer.The study included employees and spouses with T2D who participated in an annual health assessment in 20 and had medical coverage ≥12 consecutive months prior to the assessment. T2D was defined from ICD codes in claims, self-reported physician diagnosis, or having fasting glucose > 125 mg/dL or HbA1C > 6.4%. A stepwise multinomial logistic regression model was used to assess associations of healthcare engagement, diet, smoking and socioeconomic status with glycemic control. The 2,981 participants included 16% (n=484) with HbA1C > 8.5% and 27% (n=800) with HbA1C 7 to 8.5%. We found that HbA1C > 8.5% was associated with age, sex, years since last physical exam, number of complications, number of medications, and physical activity. The regression model results are shown in the figure. We conclude that poor glycemic control is common among persons with T2D despite good healthcare coverage. We identified factors associated with poor glycemic control in this population that may help design strategies to improve glycemic control.
