Relationship between sleep disordered breathing and body weight gain in male commercial drivers.

睡眠呼吸障碍(SDB)是一种睡眠时呼吸气流减少或停止的反复发作，导致白天嗜睡。在职业环境中，SDB对商业司机来说是一个重要的问题。为了研究男性商业司机睡眠呼吸紊乱与体重增加的关系，向889名30至65岁的商业司机发放了一份调查问卷。问卷包括人体测量数据、睡眠期间自我报告的鼾声和呼吸暂停、爱普沃斯嗜睡量表(ESS)和20岁时的体重。753名男性收回了调查问卷(应答率85%，平均年龄46.1±10.9岁；体重指数(BMI)23.6±3.0 kg/m^2；ESS 5.6+/-3.2)。195人(26.2%)报告了习惯性鼾声(或=每周3次)。66名受试者(8.8%)报告了目击呼吸暂停。虽然呼吸暂停患者和非呼吸暂停患者的平均年龄有差异(46.3±9.8比45.9+/-11.2岁)，但目睹呼吸暂停患者的BMI、20岁以来的增重量和ESS分别显著高于非呼吸暂停患者(24.3±3.2vs23.4+/-3.0 kg/m^2；6.7±8.0vs4.7+/-6.9 kg；6.7+/-3.0vs5.4+/-3.1)。这些结果表明，日本商业卡车司机中目击呼吸暂停的患病率相当高，而且目击呼吸暂停患者20年后比非呼吸暂停患者更容易嗜睡和体重增加。

Sleep-disordered breathing (SDB) is a condition of repetitive episodes of decreased or arrested respiratory airflow during sleep and causes daytime sleepiness. In the occupational setting, then, SDB is an important issue for commercial drivers.To examine the relationship between sleep disordered breathing and body weight gain in male commercial drivers, distributed a questionnaire to 889 male commercial drivers 30 to 65 yrs. Questionnaires consisted of questions concerning anthropometric data, self-reported snoring and apnea during sleep, Epworth sleepiness scale (ESS), and body weight at 20 yrs. Questionnaires were returned by 753 men (a response rate of 85%, mean age 46.1+/-10.9 years ; body mass index (BMI) 23.6+/-3.0kg/m^2 ; ESS 5.6+/-3.2). Habitual snoring (> or = 3 times per week) was reported by 195 subjects (26.2%). Witnessed apnea was reported by 66 subjects (8.8%). Although the mean age did differ between apnea and non-apnea subjects (46.3+/-9.8 vs 45.9+/-11.2 yrs), BMI, amount of gaining weight since 20 yrs and ESS of witnessed apnea subjects were significantly higher than those of non-apnea subjects respectively (24.3+/-3.2 vs 23.4+/-3.0 kg/m^2 ; 6.7+/-8.0 vs 4.7+/-6.9 kg ; 6.7+/-3.0 vs 5.4+/-3.1).These results show that the prevalence rate of witnessed apnea in commercial truck drivers in Japan is rather high and that the witnessed apnea subjects are sleepier and gain weight since 20 yrs, than non-apnea subjects.
