This cross-sectional study was conducted among 149 patients with type 2 diabetes mellitus (T2DM) who attended chronic disease clinics at primary care units under the supervision of Phra Narai Maharaj Hospital, Lopburi Province. The objective was to determine the prevalence and risk factors of obstructive sleep apnea (OSA) using the STOP-Bang questionnaire in patients with T2DM. Demographic and clinical data were collected, and OSA risk was assessed using the STOP-Bang questionnaire. Participants were categorized into two groups: STOP-Bang <3 and ≥3. Statistical analyses were performed using chi-square test, t-test, and logistic regression.
The results showed that STOP-Bang scores ranged from 1 to 6, with 124 participants scoring ≥3, yielding a prevalence of 83.2% (95% CI: 76.4–89.0). Participants with STOP-Bang scores ≥3 had a significantly higher mean waist circumference (91.06±11.93 cm vs. 85.75±7.21 cm, p=0.03). Univariate analysis indicated that waist circumference >80 cm was significantly associated with OSA risk (OR=12.1, 95% CI: 2.07–70.46, p<0.01), while having a bachelor’s degree was associated with a lower risk (OR=0.30, 95% CI: 0.09–0.96, p=0.04). Other variables were not significantly associated. In multivariable logistic regression, waist circumference >80 cm remained an independent risk factor for OSA (aOR=13.36, 95% CI: 2.13–83.61, p<0.01).
In conclusion, the prevalence of OSA among patients with T2DM assessed using the STOP-Bang questionnaire was high. Waist circumference >80 cm was identified as a significant independent risk factor.
