摘要

目的：橫斷性研究日本年輕女性的總反式脂肪酸、氫化或天然反式脂肪酸的攝取與選定的代謝危險因子之關係。方法：研究對象為1136名日本營養系女學生，年齡18-22歲。飲食攝取評估使用效度已確認的，自我評估飲食歷史問卷。反式脂肪酸的攝取與代謝危險因子之相關，利用多元線性迴歸分析，控制潛在的共變量。飲食共變量包括總熱量攝取、總脂肪和飽和脂肪酸（模式1），單元不飽和脂肪酸替代飽和脂肪酸（模式2），和多元不飽和脂肪酸替代飽和脂肪酸（模式3）。結果：平均（標準差）總反式脂肪酸攝取佔總熱量的0.90%（0.30%）。氫化反式脂肪酸攝取佔總反式脂肪酸的77％。總反式脂肪酸與腰圍、三酸甘油酯和糖化血紅素幾乎都有顯著的正相關，僅有校正單元不飽和脂肪酸後的三酸甘油酯例外。總反式脂肪酸攝取與身體質量指數、膽固醇或血糖沒有相關性。氫化反式脂肪酸攝取只與腰圍和糖化血紅素有顯著正相關。天然反式脂肪酸未發現有相關。結論：在相對攝取量較低的日本年輕女性中，氫化反式脂肪酸攝取與一些代謝危險因子有顯著正相關。

Objective: We examined cross-sectional associations of total, hydrogenated, and natural trans fatty acid intake with selected metabolic risk factors in young Japanese women. Methods: Subjects were 1136 Japanese female dietetic students aged 18-22 years. Dietary intake was estimated using a validated, self-administered diet history questionnaire. Associations between trans fatty acid intake and metabolic risk factors were examined with multivariate linear regression analysis, with control for potential covariates. Dietary covariates included intake of energy, total fat, and saturated fatty acids (model 1); monounsaturated fatty acids instead of saturated fatty acids (model 2); and polyunsaturated fatty acids instead of saturated fatty acids (model 3). Results: Mean (standard deviation) total trans fatty acid intake was 0.90% (0.30%) of total energy. Hydrogenated trans fatty acids contributed 77% of total trans fatty acid intake. Total trans fatty acid intake was significantly and positively associated with waist circumference, triacylglycerol, and glycated hemoglobin, except in the analysis of triacylglycerol with adjustment for monounsaturated fatty acids. No associations were found between total trans fatty acid intake and body mass index, cholesterol, or glucose. Hydrogenated trans fatty acid intake was significantly and positively associated only with waist circumference and glycated hemoglobin. No association was observed for natural trans fatty acid intake. Conclusion: hydrogenated trans fatty acid intake was positively associated with several metabolic risk factors among free-living young Japanese women with relatively low intake.
