265,118 (m; 12226, f; 142857) adults aged 40 and above were followed up for 17 years (1966-1982) and age standardized mortality rates for cancer of each site were analysed by life style variables. The study revealed smoking cessation and increased consumption of green-yellow vegetables as the most effective common way of primary prevention (e.g. cancers of lung, stomach, cervix) followed by moderation in drinking of alcohols (e.g. cancers of mouth, pharynx, esophagus, sigmoid colon) and avoidance of excess consumption of animal fat (e.g. cancer of pancreas, breast). To reduce chances of exposure to passive smoking was also considered important for selected sites (e.g. cancers of lung, nasal sinus, breast, brain tumor and leukemia).
对265118名成年人（男性12226人，女性142857人）进行了为期17年（1966年至1982年）的随访，这些成年人年龄在40岁及以上，并根据生活方式变量分析了各部位癌症的年龄标准化死亡率。该研究表明，戒烟和增加黄绿色蔬菜的摄入量是最有效的一级预防常见方法（如肺癌、胃癌、宫颈癌），其次是适度饮酒（如口腔癌、咽癌、食管癌、乙状结肠癌）以及避免过量摄入动物脂肪（如胰腺癌、乳腺癌）。对于某些特定部位（如肺癌、鼻窦癌、乳腺癌、脑肿瘤和白血病），减少接触二手烟的机会也被认为很重要。
