Alcohol consumption in relation to cardiovascular and non-cardiovascular mortality in an elderly male Chinese


The association of alcohol consumption with cardiovascular and non-cardiovascular mortality was investigated in a study population of elderly Chinese men.
1702 participants ≥60 years of age were recruited from residents living in a suburban town of Shanghai. Alcohol intake was classified as non-drinkers, past drinkers (stopped drinking for ≥12 months), and current light-to-moderate (1 to 299 g/week) and heavy drinkers (≥300 g/week). Alcoholic beverages were classified as beer/wine, rice aperitif and liquor/mix drinking.
During 5.9 years (median) of follow-up, all-cause, cardiovascular and non-cardiovascular deaths occurred in 211, 98 and 113 participants, respectively. The corresponding incidence rates were 23.6/1000, 10.9/1000 and 12.6/1000 person-years, respectively. Both before and after adjustment for confounding factors, compared with non-drinkers (n = 843), past drinkers (n = 241), but not the current light-to-moderate (n = 241) or heavy drinkers (n = 377), had a higher risk of all-cause (adjusted hazard ratio [HR] 1.90, 95% confidence interval [CI] 1.35–2.68) and non-cardiovascular mortality (HR 2.46, 95% CI 1.55–3.91). Similar trends were observed for cardiovascular mortality (HR 1.44, 95% CI 0.85–2.44).
In similar unadjusted and adjusted analyses, compared with the current beer/wine drinkers (n = 203), liquor/mix drinkers (n = 142), but not aperitif drinkers (n = 273), had a significantly higher risk of all-cause (HR 3.07, 95% CI 1.39–6.79), and cardiovascular mortality (HR 10.49, 95% CI 2.00–55.22). Similar trends were observed for non-cardiovascular mortality (HR 1.94, 95% CI 0.73–5.16).
The authors state that the study highlights the risks of mortality associated with past heavy drinking and spirit drinking in elderly Chinese men.
