目的 了解海军飞行人员主要生活习惯、体育锻炼情况、睡眠状况，以及体重指数，为增进飞行员身体健康，保障飞行安全提供科学依据。方法 采用问卷方式调查了557名海军不同机种飞行人员的吸烟、饮酒、运动及睡眠情况，并测量身高、体重，计算出体重指数，分别按照不同年龄和不同飞行机种进行对比研究。结果 （1）飞行人员吸烟比例较高，不同年龄组的吸烟比例为52.68%~55.24%；不同机种间比较无明显差异。（2）有经常饮酒习惯的飞行人员在20~29岁年龄组为8.7%，30~39岁组和40岁以上组分别达26.79%和25.17%，组间比较差异有统计学意义（P＜0.01）。（3）飞行人员保持体育锻炼习惯的比例较高，在20~29岁和30~39岁年龄组分别达98.05%和91.87%，在40岁以上年龄组比例下降至85.31%，不同机种间运输机组较其他3种机种比例偏低（P＜0.01）。（4）睡眠情况调查结果显示不同年龄组和不同机种组各组间比较无显著差异。（5）飞行人员体重指数超标比例较高，且随年龄的增长比例逐渐增高，不同机种中以运输机组体重超标比例最高。结论 飞行人员中存在不良生活习惯的比例较高，飞行员超重肥胖的比例亦较高，应对其进行干预。

Objective To investigates the current lifestyle of navy pilots, offering scientific basis for promoting the health condition of pilots and ensuring the safety of flight. Methods A questionnaire investigation on life habits was carried out in 557 pilots; their body weight, body height and body mass index (BMI) were measured, then those data were analyzed using SPSS11 soft ware. Results (1)There was a high proportion of smoking in pilots of all ages(52.68%-55.24%). No significant difference was found in all kinds of airplane groups. (2)The proportion of pilot with habit of drinking usually was 8.7% in 20-29 year old group, 26.79% in 30-39 year old group, and 25.17% in 40+ year old group. (3)There was a high proportion of doing physical exercise in pilots of all ages, which was 98.05% in 20-29 year old group, 91.87% in 30-39 year old group, and 85.31% in 40+ year old group. 76.87% of pilots often did physical exercise in transporter group, lower than that in other three groups (P<0.01). (4)Survey Results on sleeping showed that no significant difference in different age group and different airplane group. (5)There was a high proportion of overweight and obesity in pilots of all ages, which increased with age. Conclusions There is high proportion of pilots with unhygienic dietary and living habits, which are very important factors for causing overweight and obesity, and it is imperative to interfere with it.
