目的描述中国人群反式脂肪酸(TFAs)摄入量和能量摄入量(E%)的大致情况，并结合性别、年龄和地区分布，确定中国人群的主要食物来源，并考察20年来的时间变化。方法采用多中心研究方法，收集1991年至2011年中国地区9个省(市)3岁以上人群的食物消费信息。用经典的评估方法估计膳食TFA的摄入量。结果20年来，我国人群TFAs摄入量有所增加，但仍处于相对较低的水平(从0.25g/d(E%为0.11%)到0.53 g/d(E%为0.24%))，与其他国家和世界卫生组织(WHO)的推荐水平相比仍处于较低水平。总体而言，19-60岁的男性和参与者通常摄入更多含TFA的食物。东部地区人群TFAs摄入量高于西部地区，E%高于西部地区。工业来源的TFAs，特别是植物油，是中国人TFAs的主要食物来源。TFAs的自然来源在儿童和青少年中的比例逐渐增加。结论中国地区一般人群TFA摄入量和E%普遍低于推荐值。目前，限制食用植物油是减少TFA摄入量的重要手段。食品建议可以根据不同年龄和地区人口的饮食偏好进行，这对促进和促进公众健康至关重要。
Objective This study was aimed to roughly describe individual Trans Fatty Acids (TFAs) intake and the percentage of energy intake(E%), and identify major food sources in the Chinese population, taking gender, age, and regional distribution into the consideration, as well as examining temporal changes over the course of 20 years. Method This multi-center study, covering nine provinces among populations aged >= 3 in China, was conducted to collect food consumption information from 1991 to 2011. A classical assessment method was used to estimate the level of dietary TFA intake. Results Over the 20-year period, the intake of TFAs in Chinese populations had increased, but remained at a relatively lower level (from 0.25 g/d(0.11% for E%) to 0.53 g/d(0.24% for E%)) compared with that of other countries and the World Health Organization (WHO) recommended level. Collectively, males and participants aged 19-60 generally consumed more TFA-containing foods. People in eastern regions consumed more TFAs and had a higher E% than those in western area. Industrial sources of TFAs, especially vegetable oil, ranked as the principal food sources of TFAs in the Chinese population. Natural sources of TFAs have gradually increased in proportion among children and adolescents. Conclusions TFA intake and the E% are commonly under the recommended level in the general population in China. Presently, restriction of vegetable oil could be a crucial method to reduce TFA intake. It would be critical to facilitate and promote public health that food recommendations might be based on the dietary preferences for population separated by different ages and regions.
