摘要
Examine the burden of comorbid obesity associated with type 2 diabetes (T2D). The IBM® MarketScan® Explorys Claims Electronic Medical Records Data were used to identify adults with T2D, two recorded body mass index (BMI) values, and continuous insurance coverage from 1 year prior through 1 year post index date. Patients with index BMI ≥18 kg/m2 and <30 kg/m2 (normal/overweight) were matched to patients with index BMI ≥ 30 kg/m2 (obese) using propensity score matching (PSM). Using the PSM cohort, multivariable analyses examined the association between obesity and patient comorbidities, healthcare costs, and resource utilization. In the matched cohort (16,006 normal/overweight; 16,006 obese), multivariable analyses showed that obesity, compared to normal/overweight, was associated with increased odds of a diabetes-related comorbidity (Odds Ratio [OR] = 1.29; 95% Confidence Interval [CI] 1.21–1.38) and an obesity-related comorbidity (OR = 1.42; 95% CI 1.29–1.56). Obesity was also associated with significantly higher annual diabetes-related and all-cause total costs and resource utilization. This research increases the knowledge of how patients with T2D and obesity should be of greater concern for healthcare providers compared to T2D patients without comorbid obesity, given their worse comorbidity profile, increased resource utilization, and higher healthcare costs.
