Quality of life and its association with insomnia and clinical variables in type 2 diabetes.

Abstract

There is a significant increase in the number of patients with type II diabetes and consequently, Quality of Life (QOL) has become a major concern. Insomnia associated with diabetes may also influence QOL in these patients. This cross-sectional comparative study aims to assess QOL and its determinants in patients with type 2 diabetes (T2DM). It also explored the prevalence and association of insomnia with QOL in T2DM patients. The sample size comprised of 50 patients with T2DM and an equal number of healthy control subjects. Socio demographic and disease characteristics were recorded on a specially designed Performa. QOL and insomnia were assessed on WHOQOL-BREEF and ISI, respectively. The mean age of participants was 48.25 ± 19.05 years and the mean duration of illness was 5.64± 2.35 years. QOL was significantly impaired in all the four domains of WHOQOLBREF (p<0.05). Female gender, poor glycemic control, longer duration of disease, increased BMI were associated with poor QOL. Insomnia was more common in diabetics [Odds Ratio, 95% C. I. = 8.566, (3.321 to 22.094)] and had significant association with poor QOL. QOL in patients with T2DM is impaired. Several disease characteristics have negative influence on QOL in these patients. Frequent occurrence of insomnia may further deteriorate the QOL.It is important to understand risk factors associated with poor QOL to formulate an appropriate treatment strategy.
