- Abstract
Background: Individuals who have undergone long-term bariatric surgery may be at increased obstructive sleep apnea (OSA) risk. The purpose of this study was to estimate the frequency of OSA risk and its associations, via biochemical markers, in patients who have undergone long-term bariatric surgery. Methods: This cross-sectional study evaluated patients after 5 years or more post Roux-en-Y gastric bypass. Biochemical markers, anthropometrics, and OSA risk, via the STOP-Bang score screening tool, were evaluated. Independent Student t, Pearson's chi-squared, or correlation tests were applied, according to total OSA risk score groups or its isolated components. Results: Among the 77 patients evaluated (88.3% female; body mass index = 32.7 ± 5.8 kg/ m2; postoperative time = 9.9 ± 3.1 years), 36 were at risk for OSA. OSA risk score was positively correlated to high-sensitivity C-reactive protein levels (r2 = 0.270; p = 0.025), triglycerides (r2 = 0.338, p = 0.004), total cholesterol (r2 = 0,262; p = 0,028), and HbA1c (r2 = 0.332; p = 0.005). Compared to each counterpart, basal insulin and triglycerides were higher among those who self-reported witnessed apnea (12.8 ± 6.5 vs 8.1 ± 3.8, p = 0.013; 136.4 ± 41.1 vs 88.5 ± 34.8, p = 0.001, respectively), while levels of total cholesterol and LDL-C were higher in participants who reported tiredness (183.9 ± 27.0 vs 164.8 ± 33.4, p = 0.005; 105.9 ± 24.4 vs 92.0 ± 26.6, p = 0.018). Participants with snoring also had higher levels of triglycerides (107 ± 41.1 vs 83.7 ± 33.9, p = 0.010). Conclusions: OSA risk was highly prevalent among patients who had undergone long-term bariatric surgery, as noted via increased STOP-Bang scores, as were isolated components related to inflammatory markers and lipid and glycemic profile.
