Objective To investigate the prevalence of abnormity of blood lipid and associated factors in healthy population in Beijing. Methods Totally

38 462 individuals who received health examination were enrolled in our study. We divided them into eight groups according to their ages. The levels of serum total cholesterol

triglyceride

high density lipoprotein cholesterol

and low density lipoprotein cholesterol were tested

and the relationship of blood lipid abnormity with body mass index （BMI） and fasting blood glucose was analyzed. Results The incidences of hypercholesterolemia

hyperglyceridemia

low high-density lipoprotein cholesterolemia

and hyper low-density lipoprotein cholesterolemia presented increasing trend in this population. The incidence rate of abnormity of blood lipid in health examination population increased with BMI increase. The incidence of abnormity of blood lipid in overweight and obesity population was significantly higher than that in low weight and normal weight populations （P<0.05）. Meanwhile

the trend of abnormal blood lipid incidence coincided with that of abnormal fasting blood glucose. Conclusions The prevalence of overweight

obesity

and abnormity of blood lipid in Beijing presents increasing trend. The incidence of abnormity of blood lipid increases with BMI increase

in coincidence with that of fasting blood glucose.
