目的调查北京和广州两市3岁以上不同人群反式脂肪酸的摄入量以确定反式脂肪酸的高暴露食物以及高暴露人群。方法采用食物频率法调查过去3个月内被调查对象摄入各类含反式脂肪酸的食物的摄入频率以及平均每次的摄入量。结果两市的高暴露食物居第一位的均为植物油,其他食物顺位有所差异。共同的高暴露人群为13～17岁的年龄段人群和在校学生职业人群。结论两市反式脂肪酸高暴露食物与人群有所差异,其原因多样,有待进一步研究。

Objective To investigate the intakes of trans fatty acids over the age of 3 in different populations,and to determine the high exposure food and population in two cities.Methods Use food frequency survey to investigate the frequency and the average intake of food containing trans fatty acids among subjects in the past three months.Results The first ranks high exposure food is vegetable oil,while other food is different in sequence among two cities.The common high exposure populations are 13-17 years old groups and students at school groups.Conclusion The high exposure food and population are different among two cities,and the reasons are so various that we need further research.
