Background: Central obesity is the most prevalent dietary illness in people. It predisposes a person to a complicated
health issues, including stroke, type 2 diabetes, hypertension, non-alcoholic fatty liver disease, and obstructive sleep
apnea syndrome (OSAS). OSA is a chronic, progressive condition that adversely affects quality of life. Due to lower
lung capacity and tension on the pharynx, the degree of upper airway obstruction and hypoxemia owing to OSA seems
to correlate more strongly with the amount of visceral fat (abdominal adiposity) than other clinical indicators of obesity.
Objectives: Studying the relationship between central obesity and OSA incidence and severity, as well as the
underlying risk factors between their association. Subjects and Methods: This cross-sectional study included 364 adult
subjects with central obesity who visited the Endocrinology Clinic of Benha University Hospital, Egypt, from February
2023 to May 2023. All participants were subjected to measurement of weight, height and waist circumference (WC),
recording of blood pressure, laboratory investigations including: HBA1c, lipid profile, liver and kidney function tests
and overnight polysomnography to assess OSA.
Results: OSA was present in 308 (84.6%). OSA severity was closely related to male sex. Moderate and sever OSA was
significantly associated with male sex, old age, higher WC, higher BMI, diabetes, hypertension, high cholesterol,
triglycerides & LDL. Logistic regression analyses between different variables and OSA showed that age was the most
significant predictor for OSA (p
