B. Clinical Sleep Science I. Sleep Disorders – Breathing 0353 SLEEP AND BREATHING:MANAGEMENT OF SLEEP APNEA PATIENTS IN THE PUBLIC HEALTH SYSTEM OF BRAZIL Geovanini GR, Bezerra LM, Schorr F, Moulin S, Pessoa Junior RJ, Pedrosa R, Genta PR, Lorenzi-Filho G Heart Institute of University from Sao Paulo,Brazil, Sao Paulo, Brazil Introduction: The Obstructive Sleep Apnea (OSA) is a growing public health problem. Most patients remain undiagnosed and untreated. Polysomnography is the gold standard for diagnosis, however inaccessible and expensive for our population. The home polygraphy (HP) is a viable alternative. Objective: To describe an accessible model for diagnosis and treatment of OSA in patients from public health system of Brazil. Methods: Patients referred to the sleep clinic of Heart Institute of University of Sao Paulo and evaluated after the Berlin questionnaire and the Epworth Sleepiness Scale (ESS), those with high probability of OSA performed to home polygraphy:Stardust II. This device assesses airflow, pulse oximetry, respiratory effort and body position. The severity of OSA was classified according to the apnea and hypopnea index (AHI) as mild (5-14), moderate (15-29) and severe (equal to or greater than 30 events/hour). Patients with severe OSA or moderate OSA more cardiovascular comorbidities were referred to CPAP. That moderate OSA without cardiovascular comorbidities were for speech therapy and mild OSA for weight loss. Results: Caracteristics of the sample:56 patients, 70% male, mean age 53 years, mean body mass index: 32 ± 6. 9 kg/m2. Comorbidities:current smoker 17. 9% (n=10), COPD 12. 5% (n=7), atrial fibrillation 12. 5% (n=7), CHF 16% (n=9), diabetes mellitus 19. 6% (n=11), CAD 19. 6% (n=11) and hypertension 60% (n=34). Average ESS: 12 (3-23); ESS ≥10 in 57% (n=32). Obese BMI ≥30 were 55% (n=31). Snoring: 82% (n=46). Married 67.9% (n=38). The mean AHI: 27 events/hour, with most of the sample was moderate to severe apnea. Those who had minimum oxygen saturation below 90% was 75% (n=42). Only 16% (n=9) had to repeat the examination and oximetry loss represented the mainly reason for the repetition in 88% (n=7). Unfortunately, due to financial constraints, few patients were using CPAP. Speech therapy was a therapeutic option for those with moderate OSA and without disease cardiovasculares. Dos seven patients referred to speech therapy, six join treatment Conclusion: The home polygraph is an accessible model home for the management of obstructive sleep apnea patients in the public heathy system of Brazil and exercises techniques of speech therapy can help treat 0354 EFFECT OF ETHNICITY AND ACCULTURATION ON OBSTRUCTIVE SLEEP APNEA PREVALENCE AND SEVERITY IN NON-HISPANIC WHITES AND HISPANICS OF MEXICAN DESCENT IN SAN DIEGO COUNTY: PRELIMINARY FINDINGS Bercovitch R 1 , Palinkas L 3 , Ancoli-Israel S 2 , Dimsdale JE 2 , Loredo JS 1 1 Medicine, University of California, San Diego, San Diego, CA, USA, 2 Psychiatry, University of California, San Diego, San Diego, CA, USA, 3 School of Social Work, University of Southern California, Los Angeles, CA, USA Introduction: We studied the prevalence and severity of obstructive sleep apnea (OSA) in non-Hispanic whites (NHW) and Hispanics of Mexican Descent (HMD), and examined the effect of acculturation. We hypothesized that HMD would have a greater prevalence of OSA proportional to degree of acculturation. Methods: Subjects were recruited using random digit dialing as part of the Sleep Health and Knowledge in U.S. Hispanics Study. Home polysomnography (PSG) was performed. The Short Acculturation Scale for Mexican Americans was used. Results: We performed 363 PSGs (195 NHW and 168 HMD). Hispanics of Mexican descent were heavier (BMI 29.1±7.4 vs. 27.7±5, p=0.032) and younger (43. ±15.1 vs. 55.7±16.3 years old, p< 0.001) than NHW. Obstructive sleep apnea (defined as AHI ≥ 5) was highly prevalent overall (66.9%). There was no difference in average AHI between NHW and HMD (19.8±22.5 and 20.4±24.2, p=0.79) or in the prevalence of OSA (Men 77.6% vs. 70.4%; women 58.6% vs. 55.2%. p=0.117). There was no difference in the prevalence of mild, moderate, or severe OSA (defined as AHI 5 to 30 years, with matched Wisconsin Sleep Cohort participants (WSC, n=1162) to determine if Hmong are at high risk for sleep disorders that could contribute to SUNDS. Methods: Three Wisconsin population-based samples of Hmong were recruited in 1995-7 and surveyed on sleep habits and other factors. A subsample (n=37) underwent in-home polysomnography to determine apnea and hypopnea frequency (AHI).Multiple logistic regression was used to estimate odds ratios (OR) for predictors of self-reported (SR) habitual snoring and breathing pauses, both markers of sleep apnea. Results: Prevalence of sleep apnea defined by AHI>5 was higher for Hmong (54%) vs WSCS (32%) (p
