Alcohol consumption and cardiovascular diseases in rural China

A study evaluated the associations between drinking status and cardiovascular diseases in a general population from rural China.

11,269 adults were included in the study using a multi-stage cluster sampling method to select a representative sample of individuals 35 years or older. Related medical histories were obtained using a standard questionnaire, and blood biochemical indexes were collected. Participants were asked for information about whether they regularly consumed alcohol, their average alcohol consumption per day, and the number of days per month that they consumed alcohol.

This population consisted of 75.8% non-drinkers, 7.5% moderate drinkers, and 16.7% heavy drinkers. And the mean alcohol consumption per day for the total population was 15.29 ± 0.35 g/d (women: 1.0 ± 0.11 g/d and men 32.5 ± 0.69 g/d, p < 0.001). The study found that heavy drinkers had approximately a 1.3-fold and 1.7-fold greater risk for coronary heart disease and hypertension, respectively (OR: 1.252, 95% CI: 1.012 to 1.549; OR: 1.741, 95% CI: 1.519 to 1.994, respectively) compared with that of the non-drinking group. After fully adjusting the data for all variables, the data showed no significant association between moderate alcohol consumption and CHD, HT or ischemic stroke.

The authors conclude that in this population, alcohol consumption in rural populations is high, particularly in men. Heavy drinking is a risk factor for coronary heart disease and hypertension, but not for ischemic stroke. There was no significant association between moderate alcohol consumption and CHD, HT or ischemic stroke.
