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

睡眠呼吸障碍（SDB）是一种睡眠期间反复发作的呼吸气流减少或停止的情况，导致白天嗜睡。因此，在职业背景下，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障碍与体重增加之间的关系，向889名30至65岁的男性商业司机分发了一份调查问卷。问卷包括人体测量数据、睡眠中自述的打鼾和呼吸暂停、爱普沃斯嗜睡量表（ESS）和20岁时的体重。调查对象为753名男性，问卷回复率85%，平均年龄46.1+/-10.9岁，体重指数（BMI） 23.6+/-3.0kg/m^2；ESS 5.6 + / - -3.2)。195名受试者（26.2%）报告有习惯性打鼾（每周10或= 3次）。66例（8.8%）报告有目击性呼吸暂停。虽然呼吸暂停组和非呼吸暂停组的平均年龄存在差异（46.3+/-9.8 vs 45.9+/-11.2岁），但目睹呼吸暂停组的BMI、20年以来体重增加量和ESS均显著高于非呼吸暂停组（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）。这些结果表明，日本商用卡车司机见证呼吸暂停的患病率较高，且见证呼吸暂停的受试者在20年内比非见证呼吸暂停的受试者更嗜睡，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.
