摘要
目的 深入分析1990-2019年我国居民近三十年的膳食脂肪酸摄入情况的年龄和年份变化特征,为进行合理的膳食指导提供基础资料。方法 利用2019年全球疾病负担研究中的关于n-3多不饱和脂肪酸(PUFA)、PUFA和反式脂肪酸(TFAS)我国居民1990-2019年的摄入数据的估计值,采用Joinpoint回归模型分析摄入情况随年龄和年份的变化趋势特征。结果 近30年,我国居民n-3 PUFA、PUFA摄入情况均未达标。n-3 PUFA的摄入量和PUFA摄入能量占比总体呈现上升趋势,其中,n-3 PUFA摄入量增加速度随着年份推移而增加,45~74岁组在2008-2019年间摄入量增加速度较其他年龄段要快;PUFA在1996-2009年左右上升速度较快且50~84岁年龄组较其他年龄组更快,1990-1996年和2009-2019年左右上升速度较慢。TFAS摄入能量占比总体呈现下降趋势,2001-2009年左右下降速度较快且35岁及以上相对其他年龄组下降更快。结论 除n-3 PUFA外,近10年PUFA和TFAS摄入情况向好的趋势减慢。建议继续加大营养健康教育的宣传力度,促进居民n-3 PUFA、PUFA尽快达到推荐的摄入标准,尤其是青年人群。
Objective To analyze characteristics of fatty acids intake of Chinese residents from 1990 to 2019.Methods The data of n-3 polyunsaturated fatty acid(PUFA),PUFA and trans fatty acid(TFAS)intakes of Chinese residents from 1990 to 2019 were downloaded from the 2019 Global Burden of Disease Study.The Joinpoint regression model was used to analyze the changing trend by age and year.Results In the past 30 years,the intakes of n-3 PUFA,PUFA did not rearch the recommended intake levels.The overall intake of n-3 PUFA and the energy contributing proportion of PUFA intake showed an increasing trend.The n-3 PUFA intake increased with time,and the increase rate of n-3 PUFA intake in the 45-74 year group was faster than that in other age groups during 2008-2019.PUFA increased faster in 1996-2009 than in 1990-1996 and 2009-2019,and the age group 50-84 increased faster than other age groups.The energy contributing proportion of TFAS intake showed a declining trend in general,with a rapid decline from 2001 to 2009 and a faster decline in 35 years old and above compared with other age groups.Conclusion Except for n-3 PUFA,PUFA and TFAS intakes slowed down in recent 10 years.We should continue to strengthen the publicity of nutrition and health education soas to promote the consumption of n-3 PUFA,PUFA especially among young people.
