目的 描述参加中国慢性病前瞻性研究(CKB)队列的10个地区人群饮酒行为特征的地区差异.方法 CKB项目于2004-2008年在城市和农村各5个地区募集队列成员并完成基线调查.研究分析10个项目地区中512 891名30~79岁队列成员饮酒状况的基线信息,重点描述每周饮酒者饮酒行为特征的地区差异.结果 全部队列成员中,男性每周饮酒率(33.1%)高于女性(2.2%).哈尔滨(52.0%)和四川(50.2%)项目地区的男性每周饮酒率最高;甘肃(8.1%)和海口(18.8%)项目地区最低.四川项目地区男性每周饮酒者通常情况下的每周摄入酒精量(414.6 g)最高;甘肃(195.2 g)和河南(239.6 g)项目地区虽然日常饮酒量较低,但特殊情况下单日饮酒量列居前位(河南项目地区202.3 g;甘肃项目地区171.2 g).每周饮酒者中,82.6%的男性和56.6%的女性在特殊情况下的饮酒量达到狂饮状态(男>60 g,女>40 g).结论 CKB 10个项目地区的研究人群在饮酒率、饮酒量、饮酒方式、饮酒品种等饮酒行为特征上存在明显差异.
Objective To describe the regional differences on patterns of alcohol consumption across 10 study in the China Kadoorie Biobank (CKB) areas involving half a million adults.Methods The baseline survey of CKB took place in 5 urban and 5 rural areas across China during 2004-2008.Detailed information on alcohol consumption of 512 891 participants aged 30-79 years was gathered and analyzed.Results were directly standardized on age (in 10-age groups) and education (5 groups) structure of the study population for different sex.Results The overall prevalence rates of regular drinking (i.e.,at least weekly) were 33.1% among men and 2.2% among women.Among men,the prevalence rate was seen highest in Harbin (52.0%) and Sichuan (50.2%),but lowest in Gansu (8.1%) and Haikou (18.8%).Most regular drinkers in Sichuan,Hunan,and Gansu habitually drank strong spirits (≥40% alcohol content),whereas beer was most commonly consumed in Harbin and Qingdao,with rice wine most commonly used in the southern regions (Haikou,Suzhou,Zhejiang and Liuzhou).Mean alcohol consumption was highest in Sichuan (414.6 g/week).Although the mean alcohol consumptions appeared lower on reguilar occasion in Gansu (195.2 g/week) and Henan (239.6 g/week) than in other regions,the amount consumed on special occasions in these two regions were the highest (Henan:202.3 g/day; Gansu:171.2 g/day).Similar patterns were also seen in women.Of all the regular drinkers,82.6% of men and 56.6% of women reported heavy drinking episodes (men:〉60 g,women:〉40 g) on special occasions.Conclusion The patterns of alcohol consumption including prevalence,frequency,amount,binge drinking pattern,and type of alcohol beverage varied greatly among the ten areas of CKB under study.
