• Dyslipidemia in obstructive sleep apnea (OSA) has been attributed to confounding obesity and/or diabetes. This study aimed to examine lipid profiles in nondiabetic, nonobese patients with OSA and identify the possible effects of age and sex. We retrospectively evaluated the lipid parameters of 3,050 adults who underwent polysomnography. A total of 2,168 patients were excluded due to obesity (body mass index ≥ 30 kg/m ), diabetes, alcoholism, untreated hypothyroidism, lipid-lowering drug use, missing sleep data, or treatment for suspected OSA. Of 882 patients (75% males, aged 46.8 ± 12.2 years) included in the study, 88.4% had OSA. Levels of total cholesterol ( = .003), low-density-lipoprotein (LDL) cholesterol ( = .005), non-high-density-lipoprotein (non-HDL) cholesterol ( = .001), and triglycerides ( = .007) were significantly higher in patients with OSA than in those without, whereas HDL-cholesterol levels did not differ. The proportion of patients with hypercholesterolemia and/or elevated non-HDL cholesterol (>  160 mg/dL) was significantly higher in OSA than in non-OSA. Correlation analyses by sex revealed stronger and more significant relationships between lipid parameters and apnea-hypopnea index in women than in men ( = .135, < .001, vs = .080, = .043 for total cholesterol; = .111, < .001, vs = .080, = .046 for non-HDL cholesterol; = .122, < .001, vs = .061, = .107 for LDL cholesterol, respectively). In regression analysis, the rate of hypercholesterolemia increased with age ( < .001 for women and = .031 for men); non-HDL- and LDL-cholesterol levels significantly increased with OSA severity ( = .035 and = .023, respectively) and age ( = .004 and = .001, respectively) in women. After excluding confounding obesity and diabetes, patients with OSA have an impaired lipid profile including total cholesterol, LDL cholesterol, non-HDL cholesterol, and triglycerides. A significant association between dyslipidemia and OSA severity was observed in women but not in men. Basoglu OK, Tasbakan MS, Kayikcioglu M.
