| 摘要：反刍动物反式脂肪酸（R-TFA）对人体健康的影响与摄入量显著相关，超过一定摄入量对人体健康有害，在适当的摄入量范围内则对人体有益。利用1982、1992、2002年我国居民营养与健康状况调查，2010—2012年我国居民营养与健康状况监测，2012—2013年9个省、自治区统计年鉴与2012—2018年3个省统计年鉴中获得反刍动物食物消费量数据，并结合反刍动物制品的TFA含量进行数据分析，获得我国居民R-TFA摄入水平。结果发现：1982—2012年30年间我国居民R-TFA摄入量逐年上涨，其中2010—2012年我国居民平均R-TFA摄入量为0.076 g/d，且城镇高于农村；2012—2013年我国居民R-TFA的摄入量在0.055~0.191 g/d，显著低于丹麦居民R-TFA摄入量（0.8~3.4 g/d），新疆居民R-TFA摄入水平最高，为0.191 g/d；2012—2018年辽宁、陕西与河南3省居民R-TFA的摄入量总体变化不大。该研究不仅揭示我国居民R-TFA的摄入水平远低于西方国家，同时发现我国居民对其摄入量近年来总体变化不大，而R-TFA的摄入量与我国居民健康的关系有待进一步研究。 |

| Abstract：The effect of ruminant trans fatty acids (R-TFA) on human health is dose-dependent, which is harmful to human health if it exceeds a certain intake, and beneficial to human body if it is in a proper intake range. Therefore, the data of ruminant consumption was obtained by using the national nutrition and health survey in 1982, 1992, 2002, the statistical yearbook of nine provinces in 2012—2013 and the statistical yearbook of three provinces in 2012—2018. Then, the data of TFA content in ruminant product was analyzed, and the intake level of R-TFA in China was obtained. The results showed that the R-TFA intake of Chinese residents increased year by year from 1982 to 2012. In 2010—2012, the average R-TFA intake of Chinese residents was 0.076 g/d, and the average R-TFA intake in urban areas was higher than that in rural areas. From 2012 to 2013, the intake of R-TFA in China ranged from 0.055 g/d to 0.191 g/d, which was significantly lower than that in Denmark (0.8-3.4 g/d), and the highest level of R-TFA intake was in Xinjiang with 0.191 g/d. In addition, the intake of R-TFA in Liaoning, Shaanxi and Henan provinces had no significantly change from 2012 to 2018. This study not only revealed that the intake level of R-TFA in Chinese residents was far lower than that in western countries, but also found that the intake of R-TFA in China did not change much in recent years, and the relationship between the intake level of R-TFA and the health impact of Chinese residents needed to be further studied. |
