in contrast to developed countries 8 , leisure time physical activity in Bangladesh 13 is more prevalent in the lower SES group. Thus, adverse health-related behaviors might mediate the relationship between low SES and poor glycemic control. Among the comorbid conditions, being overweight/obese was generally associated with an increased likelihood of poor glycemic control in type 2 diabetics 15. Studies also noted that comorbid conditions such as hypertension 16 and depressive symptoms 17 are correlated with poorer glycemic control. Besides, hypertension, obesity, and depressive symptoms often exhibit socioeconomic patterning 18,19 , low prevalence of hypertension and overweight/obesity 18 and high prevalence of depressive symptoms 19 were observed in the low SES group. Therefore, these comorbid conditions may potentially mediate the relationship between low SES and poor glycemic control. Apart from adverse-health related behaviors and comorbid conditions, non-adherence to essential health service-related practices including irregular scheduled visits to diabetes clinic, not practicing self-monitoring of blood glucose concentrations, and reliance on alternative medicine have been known to contribute to poor glycemic control 14,20-22. Several observational studies found that underuse of recommended preventive services associated with poor glycemic control 20,21. Studies also indicated that patients who were not self-monitored their blood glucose 14 and rely on alternative medicine 22 had higher odds of having poorly controlled blood glucose compared to those who self-monitored their blood glucose and do not rely on alternative medicine. Furthermore, these essential health service-related practices vary by SES. In comparison to the high-SES group, people in the low-SES group are more likely to use low-cost and often less-effective alternative medicines and to experience barriers in the timely use of health care services according to their need 23. Accordingly, non-adherence to essential health service-related practices has been proposed as potential mediators of the association between low SES and poor glycemic control. To our knowledge, there has been only a single study regarding to examine the mediators contributing to socioeconomic inequality in glycemic control 24 , which showed that avoidance coping during a stressful event related to their diabetes (eg, to give up trying to deal with the event or to refuse to believe it is happening) and depressive symptoms mediated the relationship between SES and glycemic control. However, the contributions of mediators relating low SES to poorer glycemic control may differ according to context, suggesting the need for research in different settings. To date, there have been no studies in developing countries to assess the mediators relating low SES to poorer glycemic control. Therefore, evidence on socioeconomic disparities in glycemic control and potential mediators to mitigate this relationship is required. This study was performed to examine potential modifiable factor...
