Sleep-Disordered Breathing in the Usual Lifestyle Setting as Detected with Home Monitoring in a Population of Working Men in Japan

摘要: SLEEP-RELATED HEALTH PROBLEMS AND THEIR IMPACT ON SOCIETY INDIVIDUALS ARE A MAJOR SOCIAL ISSUE. PEOPLE WITH SLEEP-DISORDERED breathing (SDB) are at increased risk for hypertension,1,2 cardiovascular diseases,3 and mortality.3,4 However, SDB obstructive sleep apnea syndrome (OSAS) prevalent but largely undiagnosed in adults.5 In spite of this wide population patients, in-laboratory sleep-recording capacity has remained limited. This current situation presents an urgent need to move toward the use portable monitors home settings. Epidemiologic studies OSAS have been conducted not only Western countries,1–5 also Asian countries.6,7 sound estimates prevalence Japan lacking: previous Japanese limited by nonprobability samples, low response rates, small other methodologic problems. All epidemiologic on were performed with type 4 monitors.8–10 In our study, a cardiorespiratory monitoring device (also referred as 3 device) was used together actigraphy analyze SDB. Type defined devices minimum channels monitored,11 including ventilation or airflow (at least 2 respiratory movement airflow), heart rate electrocardiogram, oxygen saturation, whereas that do meet these criteria designated 4.11 Attended thought be standard method alternative polysomnography diagnosis follow-up OSAS.12 On hand, recommended because they higher percentage false-positive results high rates false negatives conflicting results.11 Most laboratory settings. Using gold limitations validity, partly subjects tend more poorly than home.11 participants asked follow their usual lifestyles, recordings home. Home closely reflects subjects' drinking sleeping habits may present different outcomes those from reports settings. Recently, obesity become major social problem Japan. The (body mass index: [BMI] ≥ 25) 1983, 1993, 2003 26.7%, 24.5% 34.4%, respectively, among male general aged 40 49 years.13 Obesity weight gain positively associated SDB.14 Thus, previously reported Japanese. The primary goal paper examine home-monitored working population. secondary test hypotheses monitor can produce reliable data lifestyles. Here, we report first study related factors
