Study on the effect of abnormal lipid metabolism of civil aviation pilots on traditional Chinese medicine constitution / 国际中医中药杂志

ABSTRACT

Objective Research on the correlation of dyslipidemia of civil aviation pilots and the TCM constitution aimed to explore that how professional environmental affects the lipid metabolism and the constitution.MethodsMeasure the lipid statusand TCM constitution of 656 pilots, and 496 of them with dyslipidemia were studied. The sample were stratified according to the age and the types of dyslipidemia, including young and middle-aged groups, only abnormal total cholesterol metabolism (TC), only abnormal triglyceride metabolism (TG), and both abnormal cholesterol and triglycerides metabolism groups and then the differences in prevalence of traditional Chinese medicine in different groups were analyzed and discussed. ResultsThe prevalence of abnormal lipid metabolism was 75.61% in 656 pilots. The top three TCM constitutions among the pilot with dyslipidemia were phlegm dampness constitution (35.89%), dampness heat constitution (33.06%) and deficiency of Yang(20.97%). If age was not considered, the prevalence of TCM constitutions were not significantly different between the groups of only abnormal TC and TG (P>0.05), while the prevalence of Yang deficiency and dampness heat constitutions of only either TC or TG abnormal group were significantly higher than those of the group of both abnormal TC, TG (χ2 values were 6.793, 5.077, P<0.05). Take age as considered, TC metabolic abnormalities in youth group, the prevalence of damp heat constitution of the only TC abnormal group was higher than both TC, TG abnormal group (χ2=7.637,P<0.01); and the prevalence of Qi deficiency and Yang deficiency constitution of the only TG abnormal group were higher than both TC, TG abnormal group (χ2values were 6.139, 7.525,P<0.05). In the middle-aged group, the prevalences of Yang deficiency and Qi stagnation constitution of only TC abnormal group were higher than only TG abnormal group (χ2 values were 9.750, 3.922,P<0.05), and the prevalence of Yang deficiency of only TC abnormal group was higher than both TC, TG abnormal group (χ2=5.208,P<0.05). The prevalence of Yang deficiency of both TC, TG abnormal group was higher than only TG abnormal group (χ2= 4.489,P<0.05). Conclusions The result showed high prevalence of dyslipidemia in the population of civil aviation pilots. Age and lipid metabolism status could affect the types of TCM constitution. Damp-heat constitution was the common type of TCM constitution in the population of the young pilot, and Yang deficiency and Qi stagnation constitution were the common types in the population of middle-aged people whose lipid metabolism were disorder. The group of only abnormal TC influence on TCM constitution more than both abnormal TC and TG.
