Title : Glycemic control and sleep quality among type II diabetics in a community in Manila
Abstract:
Diabetes Mellitus is a major public health problem worldwide. Sleep disorders frequently occur with other medical issues, making them a good indicator of general health. New research finds that later bedtime routines and poor quality of sleep are associated with poorer control of blood sugar. Upon literature search, no local studies on diabetes and sleep quality have been found. This is a cross-sectional study which aimed to assess sleep quality and its association on glycemic control in patients with type 2 diabetes in Barangay 140, Tondo, Manila. A total of 40 participants were selected through convenience sampling from June 20, 2023, to October 20, 2023. Each patient completed the Filipino version of the Pittsburgh Sleep Quality Index (PSQI) questionnaire after which, HbA1c were measured. Good sleep quality was defined as PSQI score ≤5. Descriptive statistics and detailed logistic regression analysis were used for statistical analysis. Of the 40 diabetic patients, 19 (47.24%) of them were identified as poor sleepers and 21 (52.76%) were good sleepers. Demographic factors such as income and marital status, particularly being widowed, appeared to have a more pronounced impact on sleep quality. Among the various PSQI factors, only Sleep Efficiency [OR =22.11, 95% confidence interval (CI) = 0.45 - 5.74, P = 0.022] and Daytime Dysfunction [OR =23.43, 95% confidence interval (CI) = 0.59 - 5.71, P = 0.016] exhibited a significant association with higher HbA1c levels (greater than 7%). These findings highlight the importance of considering specific sleep factors in clinical assessments and interventions for individuals with diabetes. Further studies are needed to identify for the potential causal role between sleep and altered glucose metabolism.
