不同机型海军飞行员血尿酸水平与体质量指数的相关性分析

Correlation analysis of blood urine acid and body mass index levels in the aviators flying different types of aircraft

目的通过分析不同机型海军飞行员体质量指数(body mass index,BMI)超标组血尿酸(urine acid,UA)水平与BMI相关情况,为飞行员健康保障提供科学依据。方法以2012年1月至2013年12月在我院疗养的335名海军飞行员为对象,根据BMI水平分为BMI超标组和正常组,分析比较4种机型2组UA水平以及同一机型中UA水平与BMI的相关情况。结果(1)歼击机、轰炸机BMI超标组UA水平[(359.79±68.58)μmol/L,(368.89±72.35)μmol/L]明显高于运输机[(327.82±71.19)μmol/L]和直升机[(330.36±58.67)μmol/L],差异均有统计学意义(P<0.05);与BMI正常组比较差异无统计学意义(P>0.05)。(2)运输机、歼击机、轰炸机BMI超标组BMI水平与UA水平之间均呈高度相关(均为P<0.05),BMI正常组无明显相关(均为P>0.05)。直升机BMI超标组和正常组BMI水平与UA水平均无明显相关(均为P>0.05)。结论高空飞行环境能使BMI超标组飞行员UA值和BMI密切相关,高载荷和精神因素使BMI超标组飞行员UA值明显升高。应加强不同机型飞行员血尿酸检测,科学饮食。

Objective To provide scientific evidence for the health support of the aviators flying different types of aircraft,through analyses of urine acid（ UA） levels of the aviators with high body mass index（ BMI） and normal BMI. Methods Three hundred and thirty-five naval aviators,who stayed in the sanitarium from January,2012 to December,2013,were chosen as our research subjects.In accordance with the BMI,they were divided into the high body mass index group and the normal BMI group. Then,comparisons and analyses were made in the UA levels of the aviators of the 2 groups flying 4 different types of aircraft,as well as the correlation between UA levels and BMI in the aviators flying the same type of aircraft. Results（ 1） The UA levels of the high BMI group flying fighters and bombers [（ 359. 79 ± 68. 58） μmol / L,（ 368. 89 ± 72. 35） μmol / L] were significantly higher than those of the aviators flying transports[（ 327. 82 ±71. 19） μmol/L]（ P〈0. 05 and P〈0. 01） and helicopters [（ 330. 36 ±58. 67） μmol/L]（ P〈0. 05）. For the aviators of the normal BMI group,no differences could be seen in the UA levels.（ 2） There was high correlation between BMI and UA levels in the aviators with high BMI flying transports,fighters and bombers（ P〈0. 05）. And no correlation could be noted in those aviators with normal BMI（ P〉0. 05）. In the helicopter aviators with high normal BMI and normal BMI,there was no significant correlation between BMI and UA levels（ P〈0. 05）. Conclusion For the aviators with high BMI,high altitude flying operation had direct impact on the correlation between UA and BMI. High load and mental factor as well could evidently elevate the level of UA in the aviators with high BMI. Efforts should be made to detect the UA levels of the aviators flying different types of aircraft and good eating habits should be established.
