Glycemic control and its determinants among people with type 2 diabetes mellitus in Ernakulam district, Kerala

Diabetes is a public health problem of colossal proportions. The National Family Health Survey 5 (2019-2020) has found high blood sugar levels among 13.5% of women and 15.6% of men in India. The high morbidity and mortality in diabetes mellitus are due to uncontrolled hyperglycemia resulting in micro- and macrovascular changes affecting multiple organs in the body. The objectives of this study were to estimate glycemic control and its determinants among type 2 diabetics in the Ernakulam district.

A community-based cross-sectional study was conducted among 364 type 2 diabetics who had the disease for at least 5 years duration in the Ernakulam district of Kerala. Probability proportional to size cluster sampling technique was adopted. A semi-structured questionnaire was used to collect sociodemographic and behavioral profiles. Participants' HbA1c levels were assessed to determine glycemic control.

The proportion of people with good glycemic control was 21.4%. Determinants such as female gender adjusted odds ratio (aOR = 2.36, P = 0.005), body mass index >23 kg/m² (aOR = 2.71, P = 0.002), combined drug treatment with Oral Hypoglycaemic agents (OHA) and insulin (aOR = 3.76, P = 0.004), and poor compliance with medications (aOR = 1.93, P = 0.030) were found to be significantly associated with poor glycemic control.

Poor compliance with medications and unhealthy lifestyle choices has resulted in a high proportion of diabetics with poor glycemic control in the district. Women are particularly more vulnerable to uncontrolled hyperglycemia than males. Type 2 diabetes mellitus people should be encouraged to maintain strict glycemic control, which is an important measure for secondary prevention of complications.
