[Prevalence of hyperlipidemia and possible risk factors in rural Chinese adults: cohort study of health population in Yuhuan rural].
OBJECTIVE
To examine the prevalence of hyperlipidemia and its related factors in adults in rural Yuhuan, China.


METHODS
A cross-sectional study was carried out as a baseline study of Rural Yuhuan Health Population Cohort in all communities in Yuhuan County, Zhejiang Province, China. A total of 118,571 subjects aged 35 years old or above participated in this study. The trained health/medical workers collected the general information, health conditions and so on by the face-to-face interview. Totally, 5 ml blood samples were taken. Hyperlipidemia was defined as blood triglyceride > or = 1.70 mmol/L and/or total cholesterols > or = 5.18 mmol/L. SPSS 16.0 was used for statistical analysis. Data of the fifth China population census 2000 was used as the standard population.


RESULTS
Among 118,571 eligible subjects, the averages of blood triglyceride and total cholesterols were (1.71 +/- 14.42) mmol/L and (5.48 +/- 40.25 ) mmol/L, respectively, and there was a statistical difference in gender on blood triglyceride (t = 4.163, P < 0.001) but not on blood total cholesterols. The crude prevalences of hyperchol-esterolemia, hypertriglyceridemia, both hypercholesterolemia and hypertriglyceridemia, and hyperlipidemia were 38.4%, 24.2%, 13.2% and 49.3% and the age-standardized prevalence were 36.6%, 23.8%, 12.7% and 47.7% based on 2000 China national population, respectively. These prevalences were higher in male than in female significantly and varied statistically over different age groups from the lowest group of 35-39 years old to highest group of 55-59 years old or 60-64 years old. A non-conditional binary logistic model showed that age, male, farmer, education levels, smoking, alcohol consumption and body mass index were significantly related to hyperlipidemia.


CONCLUSIONS
Hyperlipidemia, especial hypercholesterolemia, was common in adults aged 35 years old or above living in rural China.
