飞行员体重指数与血浆抵抗素水平的关系

The relationship between body mass index and plasma resistin level in pilots

目的 对比间隔 12年两组飞行员中体重指数 (BMI)的变化情况 ,探讨BMI与血浆抵抗素水平之间的关系 ,为飞行员心脑血管疾病的一级预防提供客观依据。 方法 对比 1989年调查的 6 36名飞行员和 2 0 0 1年调查的 86 1名飞行员的BMI,用酶标法测定血浆抵抗素水平。 结果 ①1989年调查的飞行员BMI≥ 2 4者占 2 6 .7% ,≥ 2 8者占 2 .4 % ,2 0 0 1年调查的飞行员则分别为 4 5 .1%和 5 .8% ,12年上升了 5 0 %以上 ;②在飞行员中 ,BMI≥ 2 4者抵抗素水平明显高于BMI <2 4者 (P <0 .0 5 )。 结论 ① 2 0 0 1年调查飞行员中超重者十分普遍 ,已达 4 5 .1% ,与国内经济发达地区 ( 5 0 % )超重的情况十分接近 ,应积极干预 ;②在飞行员中 ,超重者血浆抵抗素水平明显升高 ,是否预示今后发展成为糖尿病的可能性较大 。

Objective To investigate the change of body mass index (BMI) of pilots in recent 12 years and the relationship between BMI and plasma resistin level so as to provide basis for prevention of cardio cerebral vascular diseases in pilots. Methods BMI of 861 pilots of various age groups investigated in 2001 was compared with that of 636 pilots in 1989. The plasma resistin level was measured in 12 normal and 12 overweight pilots with enzyme linked immunoadsorbent assay(ELA). Results 1. The pilots with BMI≥24 accounted for 26.7% and BMI≥28 accounted for 2.4% in 1989,while percentage of pilots with BMI≥24 was up to 45.1% and BMI≥28 up to 5.8% in 2001. 2.The plasma resistin level of pilots with BMI≥24 was significantly higher than that of pilots with BMI< 24 ( P <0.05). Conclusion 1. The problem of overweight became more widespread (45.1%) among pilots in recent years, and interfering measures should be taken. 2.Whether the high plasma resistin level in the overweight pilots suggests the higher possibility of developing diabetes in the future should be followed up.
