贵阳市部分体检人群饮食行为对血脂异常的影响

Effect of Dietary Behavior on Dyslipidemia Detected in Physical Examination in Guiyang

目的:探讨贵阳市常规体检人群饮食行为对血脂异常的影响。方法:选取健康体检的1838名体检者为研究对象,使用自行设计的调查表收集被调查者的一般情况和饮食行为,清晨空腹采静脉血检测总胆固醇(TC)、低密度脂蛋白(LDL-C)、高密度脂蛋白(HDL-C)和甘油三酯(TG);采用二元Logistic回归分析饮食行为对血脂异常的影响。结果:1838名试检者中血脂异常患病人数为587名,总体血脂异常患病率31.9%,男女血脂异常患病率分别为45%、16.8%,男性高于女性,不同年龄段血脂异常患病率差异有统计学意义(P<0.001),趋势χ2结果显示血脂异常患病率有随年龄先增加后降低的趋势(P<0.001);二元Logistic回归分析显示,45~59岁段人群(OR=1.863,P<0.001)、进食速度较快(OR=1.328,P=0.011)、饮食口味偏甜(OR=1.819,P<0.001)是血脂异常的危险因素;早餐3~4次/周(OR=0.504,P=0.018)、早餐5~6次/周(OR=0.482,P=0.012)、早餐>6次/周(OR=0.293,P<0.001)、每天摄入牛奶200~400mL(OR=0.714,P=0.046)和经常饮茶(OR=0.771,P=0.023)是血脂异常的保护因素。结论:贵阳市体检人群血脂异常患病率较高,饮食行为与血脂密切相关,良好的饮食行为对预防血脂异常有重要意义。

Objective: To investigate the effect of dietary behavior on dyslipidemia in physical check takers in Guiyang City. Methods: A total of 1 838 physical check takers as subjects,a self-designed questionnaire was used to collect the general conditions and dietary behavior of the respondents.In the morning,fasting venous blood was collected to detect cholesterol (TC),low density lipoprotein (LDL),high density lipoprotein (HDL) and triglyceride (TG).The effect of dietary behavior on abnormal blood lipid was analyzed by binary logistic regression. Results: The prevalence of dyslipidemia in this group was 587,and the overall prevalence of dyslipidemia was 31.9%.The prevalence of dyslipidemia in men and women was 45% and 16.8% respectively.The data of man was higher than that of woman.The prevalence of dyslipidemia in different age groups was statistically significant ( P <0.001).The trend of C2 results showed that the prevalence of dyslipidemia increase first then decrease with age ( P <0.001).Binary Logistic regression analysis found that,age ranged from 45 to 59 years old ( OR=1.863,P <0.001),eating speed is relatively fast( OR=1.328,P =0.011),preferring sweet diet ( OR=1.819,P <0.001) which were risk factors of dyslipidemia.While eating breakfast 3~4 times per week ( OR=0.504,P =0.018),eating breakfast 5~6 times per week ( OR=0.482,P =0.012),eating breakfast more than 6 times a week ( OR=0.293,P <0.001), intake 200~400 mL of milk per day ( OR=0.714,P =0.046) and frequent drinking tea ( OR=0.771,P =0.023) were protective factors of dyslipidemia. Conclusion: The prevalence of dyslipidemia is high in the physical check takers in Guiyang.Dietary behavior was closely associated with the dyslipidemia.A good dietary behavior plays a significant role in preventing dyslipidemia.
