Prevalence of dyslipidemia and the risk factors analysis of 39 980 subjects in Urumqi

Abstract

Objective To analyze the prevalence of dyslipidemia and the risk factors of 39 980 subjects in Urumqi and to explore the characteristics of dyslipidemia's risk factors. Methods The following parameters of the subjects were determined: total cholesterol(TC), triglycerides(TG), high density lipoprotein(HDL), low density lipoprotein(LDL), body mass index(BMI), waist circumference, systolic blood pressure, diastolic blood pressure, blood sugar, and uric acid. The prevalence of dyslipidemia of different gender or age and risk factors for dyslipidemia were analyzed. Results Dyslipidemia total detection rate was 55.15%, the rate in male(66.03%)was significantly higher than in women(41.72%)(χ2=2 360.034, P< 0.001); and in the men the various types of dyslipidemia detection rate was higher than those in the female, the TC(χ2=66.860, P<0.001)and TG(χ2=2 756.572, P<0.001), LDL-C(χ2=258.636, P<0.001), HDL-C(χ2= 2 714.685, P<0.001)were significantly higher in men than in women; the detection rate of dyslipidemia increased with age, and then decreased gradually in the age group 50-59 years after the peak, the(high total cholesterol(χ2=2 529.462, P<0.001), hypertriglyceridemia(χ2=1 389.313, P<0.001)high LDL-C(χ 2= 1 552.074, P<0.001), low HDL-C(χ2=97.279, P<0.001)of all age groups the dyslipidemia detection rate differences were statistically significant. Risk factors of dyslipidemia: Logistic regression analyses showed that male gender(OR=1.681; 95%CI: 1.337-1.928), age(OR=1.299; 95%CI: 1.270-1.330), high diastolic blood pressure(OR=1.248; 95%CI:1.145-1.361), high waist circumference(OR=1.895 ;95%CI: 1.638-1.956), high uric acid(OR=1.200; 95%CI: 1.094- 1.317), high blood glucose(OR=1.366; 95%CI: 1.229- 1.517), high TG(OR=4.043; 95%CI: 3.770-4.335), high LDL-C(OR=40.148; 95%CI:37.341-43.166), low HDL-C(OR=1.982 ; 95%CI: 1.432- 2.511)were closely correlated with the high TC; male(OR=1.956 ; 95%CI : 1.853-2.066), high age(OR=1.060; 95%CI:1.040-1.080), high BMI(OR=2.097; 95%CI:1.968-2.235), high diastolic blood pressure(OR=1.512; 95%CI: 1.411- 1.620), high waist circumference(OR=1.397; 95%CI: 1.313- 1.478), high uric acid(OR=2.146; 95%CI: 1.995- 2.308), high blood glucose(OR=1.498; 95%CI:1.375-1.631), high TC(OR=4.030; 95%CI:3.821-4.250), low HDL-C(OR=4.003; 95%CI:3.764-4.258)were closely correlated with the high TG. Conclusion The prevalence of dyslipidemia is high in Urumqi area. Improving prevention knowledge, attention to life style, regular physical examination, abnormal condition in time, are important to prevent and reduce the occurrence of vascular diseases.
