Background Dyslipidemia is a major health problem in China and an important modifiable cardiovascular disease (CVD) risk factor. This study aimed to describe the prevalence of dyslipidemia and low high density lipoprotein cholesterol (HDL-cholesterol) and associated risk factors among adults in rural northwest China. Methods In a cross-sectional analyses involving 2,980 adults aged >18 years, information on the demographics, cigarette smoking, alcohol consumption, education, and medical history was collected via face-To-face interviews. Blood samples were collected to determine total cholesterol (TC), low-density lipoprotein cholesterol (LDL-cholesterol), and HDL-cholesterol, and triglycerides (TG) levels. Results The prevalence of high TC, high LDL-cholesterol, low HDL-cholesterol, and high TG were 1.0%, 0.6%, 60.9%, and 13.7%, respectively. TC, LDL-cholesterol, and TG increased with age in females. Elevated TC was more common in females than in males. The prevalence of low HDL-cholesterol was 67.6% in males and 55.4% in females. Current smokers, those with less education, those who were overweight or obese, and those with large waist circumference were more likely to have low HDL-cholesterol (p<0.05). Multivariable regression showed that male gender showed an association with low HDL-cholesterol (OR 2.10, 95%CI 1.68-2.61), age-60 years (OR 0.80, 95% CI 0.64-0.99), BMI (BMI = 24-27.9, OR 1.27, 95%CI 1.04-1.54, p = 0.02 and BMI-28, OR 1.56, 95%CI 1.10-2.20, p = 0.01) and enlarged waist circumference (OR 2.10, 95%CI 1.51-2.92). Non-Alcohol drinker was associated with low HDL-cholesterol levels (OR 0.72, 95%CI 0.53-0.99, p = 0.04). Conclusions This study found that the prevalence of low HDL-cholesterol was 67.6% and 55.4% for males and females. Male gender, non-Alcohol drinker, BMI and central obesity were important risk factors for low HDL-cholesterol in Chinese adults. © 2015 Ge et al.
