Poor sleep quality and its associated factors among patients with type 2 diabetes mellitus attending an upazila health complex in Bangladesh: A cross-sectional study

Background: Sleep problems maybe negatively impact diabetes management and overall well-being. But studies examining sleep quality among rural Bangladeshi adults suffering from T2DM remain few. This study examines sleep quality of and its associated factors among adult patients with T2DM visiting a rural health facility. Methods: A facility-based cross-sectional study was carried out among 108 adult T2DM patients at Raipur Upazila Health Complex, Lakshmipur, Bangladesh, via convenience sampling. The data were collected by using a structured questionnaire and the Pittsburgh Sleep Quality Index (PSQI; Cronbach's α=0.681). Results: In all, 106 (98.1%; 95% CI: 93.5-99.5%) respondents had poor sleep quality, whereas only two (1.9%) had good sleep quality. Preliminary bivariate analyses revealed statistically significant relationships of sleep quality categories with age (p=0.03), occupation, monthly family income, family type, sleep duration, and nighttime awakenings (all p≤0.001). Some variables of demographics and diabetes did not show any statistically significant relationship. Conclusion: In the present study population, poor quality sleep was very common, indicating the need to include sleep evaluation in diabetic patients’ clinical practice. These results should be taken with caution due to the limited number of subjects with good quality sleep and the convenient sample.
