This study examined the association between consumption of alcoholic beverages and all-cause and cardiovascular disease (CVD) mortality in a cohort of men (n = 31,367). In the Cox proportional hazards model adjusted for age, year of examination, body mass index (BMI), smoking, family history of CVD, and aerobic fitness, there were no significant differences in risk of all-cause mortality across alcohol intake groups. Risk of CVD mortality was reduced 29% in quartile 1 (HR = 0.71, 95% confidence interval (CI): 0.53, 0.95) and 25% in quartile 2 (HR = 0.75, 95% CI: 0.58, 0.98). The amount of alcohol consumed to achieve this risk reduction was <6 drinks/week; less than the amount currently recommended. The addition of other potential confounders and effect modifiers including blood pressure, insulin sensitivity, lipid levels, and psychological variables did not affect the magnitude of association. Future research is needed to validate the current public health recommendations for alcohol consumption.
本研究在一组男性(n = 31367)中检验了酒精饮料消费与全因死亡率和心血管疾病(CVD)死亡率之间的关联。在根据年龄、检查年份、体重指数(BMI)、吸烟、CVD家族史和有氧适能进行调整的Cox比例风险模型中,各酒精摄入量组的全因死亡风险无显著差异。四分位数1的CVD死亡风险降低了29%(风险比[HR]=0.71,95%置信区间[CI]:0.53,0.95),四分位数2降低了25%(HR = 0.75,95% CI:0.58,0.98)。实现这种风险降低所需的酒精摄入量<6杯/周;低于目前推荐的量。纳入其他潜在混杂因素和效应修饰因素,包括血压、胰岛素敏感性、血脂水平和心理变量,并不影响关联的强度。需要进一步的研究来验证当前关于酒精消费的公共卫生建议。
