Relationship Between Alcohol Consumption and Serum Lipid Profiles Among Middle-Aged Population in China: A Multiple-Center Cardiovascular Epidemiological Study

We assessed the relationship between alcohol consumption and serum lipids in a middle-aged Chinese population. The overall prevalence of drinking among 10 154 participants was 34.07% in males and 3.61% in females. Heavy alcohol drinkers ( 30 g/d) tended to be older, smokers, hypertensive, do heavy physical activity, and have a lower body mass index. Levels of high-density lipoprotein cholesterol (HDL-C), apolipoprotein (apo) A1, low-density lipoprotein cholesterol-HDL-C ratio, and apo B-apo A1 ratio rose with increase in alcohol intake in males. An increase of 0.27 mmol/L in triglycerides and a decrease of 2.10 mg/dL in lipoprotein(a), Lp(a), were observed in male alcohol drinkers who consumed 30 g alcohol/d compared with abstainers after controlling for all confounders. Levels of total cholesterol, HDL-C, and apo A1 increased with increase in alcohol intake in both genders and Lp(a) decreased with the increase in alcohol intake in males.
