Objective: To identify subjects at high risk for obstructive sleep apnea (OSA) using STOP-BANG questionnaire and Epworth Sleepiness Scale (ESS) in a young adult population assisted by a Family Health Program unit in Rio de Janeiro – LapARC cohort study Design and method: This is a cross-sectional population study enrolling young adult between 20–50 years. The eligible population consisted of all 1,795 residents in Rio de Janeiro downtown, previously registered in Family Health Program unit. This pilot project intends to evaluate 15% of the total population at this first moment. Demographic and anthropometric (height, weight, and abdominal and neck circumference) characteristics were registered. All patients underwent to office and home blood pressure (BP) measurements, and application of OSA screening tools. STOP-BANG stands for: snoring, tired during the day, observed stop breathing, high BP, body mass index (BMI), age >50 years, neck circumference >40 cm and male gender. ESS is an 8-item questionnaire asking the subject how likely he/she is to doze off or fall asleep in situations of daily life. STOP-BANG score > 3 and/or ESS score > 10 identify patients at high risk for OSA. Results: A total of 270 subjects [34.2% males, mean(SD) age: 38 (9) years] were enrolled. The prevalence of hypertension was 18%. Mean (SD) BMI was 27.9 (5.9)kg/m2 and neck circumference was 37(5)cm. High risk at STOP-BANG, ESS and both was found in 25.3, 31.9 and 14.3% of the subjects, respectively. High risk patients are more frequently obese men, with higher prevalence of dyslipidemia (54 vs 16%), higher mean (SD) office (135(15)/83(10) vs 121(13)/76(9)mmHg) and home (134(15)/84(10) vs 116(12)/72(12) mmHg) BP. They also had higher mean (SD) BMI (34(6) vs 28(5)kg/m2), neck (44(4) vs 36(5)cm) and waist (108(14) vs 89(14) cm) circumference. Conclusions: The prevalence of subjects at high risk of OSA was higher than expected for this young and health population especially in those with obesity and higher BP levels. The early detection of OSA in young population in primary care is a challenge to health system and can probably reduce the future cardiovascular risk
