Abstract:
Objective:To understand the dyslipidemia rate and trend of blood lipid level in an urban community in Hangzhou.
Methods:A total of 1 485 urban community residents aged 24 years or older who had participated in health checkup over 6 years, from 2011-2016, were selected by random cluster sampling. Fasting blood Triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) levels were measured in all subjects. A χ2 test was used to analyze the dyslipidemia rate trend, and an ANOVA of repeated measurement was conducted to observe the blood lipid level changes.
Results:From 2011 to 2016, the total abnormal rates of blood lipids in 1 485 residents were 33.2% (493/1 485), 30.5% (453/1 485), 30.4% (452/1 485), 26.5% (394/1 485), 26.3% (391/1 485), and 25.1% (373/1 485), respectively, which showed a declining trend year-by-year (χ2=36.051, P<0.01). Among these results, however, the high TG rate did not significantly differ from year-to-year (χ2=10.081, P>0.05). The TG, TC, LDL-C, and HDL-C levels statistically differed over the 6 years (F=4.876, 33.033, 170.254, 58.442, respectively, all P<0.01). LDL-C was the highest in 2011 [(3.02±0.29) mmol/L] and the lowest in 2016 [(2.72±0.71) mmol/L], while HDL-C was the highest in 2016 (1.44±0.33 mmol/L) and the lowest in 2011 [(1.35±0.30) mmol/L]. Time-sex group interaction effect analysis: TC and HDL-C levels showed different trends over time between men and women (F=2.556, 4.982, respectively, all P<0.05), and the TC level in the male group was significantly lower than in the female group, since 2012. Interaction effect of time age group: TC and LDL-C levels showed different trends between age groups over time, and the declining trend of TC and LDL-C in the elderly group was more significant than in the young or middle age group (F=10.328, 3.085, respectively, all P<0.01).
Conclusions:The community population showed an overall improvement in blood lipid levels; however, there was no significant improvement in high TG levels. It is necessary to continue monitoring blood lipid levels in the community, especially to strengthen the prevention and control of high TG levels.
