To assess the association of proportions of fatty acids in cholesterol esters with the risk of premature death from cancer in middle aged men.
Prospective cohort study.
Paris, France.
3277 working men aged 36-52 in 1981-5.
Cancer mortality during an average of 9.3 years of follow up.
59 men died of cancer during follow up. The age adjusted relative risks for men in the highest thirds of the distribution of the proportions of linoleic, palmitoleic, and oleic acid in cholesterol esters as compared with those in the corresponding lowest thirds were 0.16 (95% confidence interval 0.05 to 0.51), 3.39 (1.63 to 7.05), and 4.22 (1.95 to 9.12), respectively. Adjustment for and stratification by smoking, alcohol consumption, serum cholesterol concentration, and body mass index did not alter the results. At the time of examination subjects with cancer had a lower intake of polyunsaturated fats, assessed by 24 hour recall, than those without cancer (13.2 v 17.4 g/day, P < 0.01).
Monounsaturated and polyunsaturated fatty acids of cholesterol esters are strong biological markers that predict premature death from cancer in French men. Consistently, intake of polyunsaturated fats did not seem to increase the risk of death from cancer. The association of biological markers of dietary fat intake with incidence of and mortality from cancer should be investigated prospectively in other populations.
评估胆固醇酯中脂肪酸比例与中年男性癌症过早死亡风险之间的关联。
前瞻性队列研究。
法国巴黎。
1981 - 1985年期间3277名年龄在36 - 52岁的在职男性。
平均9.3年随访期间的癌症死亡率。
随访期间59名男性死于癌症。与胆固醇酯中亚油酸、棕榈油酸和油酸比例分布处于相应最低三分位数的男性相比,处于最高三分位数的男性经年龄调整后的相对风险分别为0.16(95%置信区间0.05至0.51)、3.39(1.63至7.05)和4.22(1.95至9.12)。对吸烟、饮酒、血清胆固醇浓度和体重指数进行调整及分层后,结果未改变。在检查时,通过24小时回忆法评估,患癌症的受试者摄入的多不饱和脂肪比未患癌症的受试者少(13.2对17.4克/天,P<0.01)。
胆固醇酯中的单不饱和脂肪酸和多不饱和脂肪酸是预测法国男性癌症过早死亡的强有力生物标志物。一致的是,多不饱和脂肪的摄入似乎并未增加癌症死亡风险。饮食脂肪摄入的生物标志物与癌症发病率和死亡率之间的关联应在其他人群中进行前瞻性研究。
