摘　　要：目的分析中国成年居民营养健康知识水平的年龄分布特点。方法于2021年利用多阶段整群随机抽样法抽取全国302个调查点共102398名18~64岁常住居民进行问卷调查,最终纳入98567人,均值和率的计算都经过复杂抽样加权处理。结果中国18~24岁、25~34岁、35~44岁、45~54岁、55~64岁居民营养健康知识得分分别为(65.1±11.4)分、(64.6±11.7)分、(64.7±12.0)分、(62.2±12.8)分和(59.5±13.3)分,营养健康知识知晓率分别为20.3%、19.1%、20.3%、16.9%和12.1%,不同年龄组间营养健康知识得分及知晓率差异均具有统计学意义(P<0.001)。不同性别、城乡居民的营养健康知识水平随着年龄升高均呈下降趋势(β<0,P_(trend)<0.001),而不同文化程度下,营养健康知识水平随年龄变化的趋势不同。不同年龄段正确率<30%的知识点存在差异。结论2021年中国各年龄段成年居民营养健康知识水平均较低,但知识短板有所不同。OBJECTIVE To analyze the age distribution of nutrition and health knowledge level of Chinese residents aged 18-64.METHODS A total of 102 398 residents aged 18-64 were selected from 302 survey sites in China by multi-stage cluster random sampling method, a total of 98 567 respondents were included in the study. Both mean and rate were calculated by complex sampling weighting.RESULTS The nutrition and health knowledge score of residents aged 18-24, 25-34, 35-44, 45-54 and 55-64 years old in China were(65.1±11.4) points,(64.6±11.7) points,(64.7±12.0) points,(62.2±12.8) points and(59.5±13.3) points. The nutrition and health knowledge awareness rates were 20.3%, 19.1%, 20.3%, 16.9% and 12.1%, respectively(P<0.001). A decreasing trend in all dimensions and overall nutrition and health knowledge with increasing age was found(β<0,P_(trend)<0.001).This trend was also reflected across gender or regions. While the trend of nutrition and health knowledge level with age varies with different literacy levels. Differences in knowledge points with positive response rates <30% by age groups.CONCLUSION The level of nutrition and health knowledge among Chinese adult residents of all ages is relatively low in 2021, but the knowledge shortcomings are different.
