Abstract
Type 2 diabetes leads to severe nocturnal hypoxemia, with an increase in apnea eventsand daytime sleepiness. Hence, we assessed sleep breathing parameters in the prediabetes stage.A cross-sectional study conducted on 966 middle-aged subjects without known pulmonary disease(311 patients with prediabetes and 655 controls with normal glucose metabolism) was conducted.Prediabetes was defined by glycated hemoglobin (HbA1c), and a nonattended overnight home sleep study was performed. Participants with prediabetes (n = 311) displayed a higher apnea–hypopneaindex (AHI: 12.7 (6.1;24.3) vs. 9.5 (4.2;19.6) events/h, p < 0.001) and hypopnea index (HI: 8.4 (4.0;14.9)vs. 6.0 (2.7;12.6) events/h, p < 0.001) than controls, without differences in the apnea index. Altogether,the prevalence of obstructive sleep apnea was higher in subjects with prediabetes than in controls(78.1 vs. 69.9%, p = 0.007). Additionally, subjects with prediabetes presented impaired measurementsof the median and minimum nocturnal oxygen saturation, the percentage of time spent with oxygensaturations below 90%, and the 4% oxygen desaturation index in comparison with individualswithout prediabetes (p < 0.001 for all). After adjusting for age, sex, and the presence of obesity,HbA1c correlated with the HI in the entire population (r = 0.141, p < 0.001), and the presence ofprediabetes was independently associated with the AHI (B = 2.20 (0.10 to 4.31), p = 0.040) as well asthe HI ( B = 1.87 (0.61 to 3.14), p = 0.004) in the multiple linear regression model. We conclude thatprediabetes is an independent risk factor for an increased AHI after adjusting for age, sex, and obesity.The enhanced AHI is mainly associated with increments in the hypopnea events.
