OBJECTIVES: Diabetes and obesity are escalating in adults which increase risk of developing non communicable diseases. Studies on patients with diabetes and/or obesity show that factors like patients in rural communities, type of insurance, gender, race, age have reported difference in access to health care. In order to understand health related issues it is important to study factors influencing access to health care for co-occurrence of diabetes and obesity. The aim of this study is to investigate the hypothesis that access to healthcare is different for diabetic patients with and without obesity.   METHODS: Medical Expenditure Panel Survey (MEPS) 2008 data was analyzed for diabetic patients with and without obesity. Access to health care was measured as patients who reported to have usual source of care (USC) provider. Logistic regression and goodness of fit tests were conducted to get the best fit model. All analysis was performed by using STATA 11.  RESULTS: A total of 2346 adult patients had diabetes; where 1193 (50.8%) had diabetes and obesity while 1078 reported to have USC provider. Logistic regression analysis shows that patients with both diabetes and obesity had better access to health care (OR=1.3432, p=0.037) compared to only diabetic patients. Patients with public insurance (OR= 3.9877 P=0.000), who report that it is sometimes easy to get needed health care (OR=1.56 P=0.031) and have excellent perceived health status (OR=3.416, P=0.001) are more likely to report higher access to healthcare. Age was the only demographic factor found statistically significant showing older adults (54 to 85) had better access to health care (OR=2.081, p=0.002).   CONCLUSIONS: Comorbidities are associated with higher access to healthcare. This could be due to higher utilization of healthcare by patients with comorbid conditions, older age and providers focusing more on treatment of diseases than prevention.
