摘　　要：目的了解南京市小学四年级学生液态奶制品饮用情况,并分析其影响因素。方法于2020年9月采用多阶段整群随机抽样方法抽取南京市小学四年级学生为调查对象,采用问卷调查收集基本信息、调查前1周液态奶制品摄入频次和每次平均摄入量等资料。参考《中国居民膳食指南(2016)》,以每周液态奶制品摄入量≥2100 g为达标;采用多因素logistic回归模型分析液态奶制品摄入频次和摄入量的影响因素。结果发放问卷2268份,回收有效问卷2216份,回收有效率为97.71%。男生1199人,占54.11%;女生1017人,占45.89%。学生液态奶制品摄入频次为(6.41±4.86)次/周,摄入量M(QR)为1250.00(1750.00)g/周。摄入量达标607人,占27.39%。摄入频次≥7次/周1016人,占45.85%。多因素logistic回归分析结果显示:城区(OR=1.204,95%CI:1.005~1.443)、知晓营养标签(OR=1.221,95%CI:1.021~1.460)、定期测量体重(OR=1.486,95%CI:1.098~2.011)和父母限制饮用含糖饮料(OR=1.264,95%CI:1.005~1.590)是液态奶制品摄入频次≥7次/周的促进因素;定期测量体重(OR=1.821,95%CI:1.240~2.676)是液态奶制品摄入量达标的促进因素。结论南京市小学四年级学生液态奶制品摄入量不足;主要影响因素为地区、知晓营养标签、定期测量体重和父母限制饮用含糖饮料。Objective To investigate the intake of liquid dairy products and identify its influencing factors among the fourth grade students in Nanjing City.Methods The fourth grade students were selected as the study subjects in Nan⁃jing City using a multi-stage random cluster sampling method in September 2020.Their general information,frequency of liquid dairy product intake one week prior to survey and mean intake amount per time were collected.According to the 2016 Dietary Guidelines for Chinese Residents,weekly intake of liquid dairy products of 2100 g and greater was de⁃fined eligible.Factors affecting the frequency and amount of liquid dairy product intake were identified using multivari⁃able logistic regression analysis.Results A total of 2268 questionnaires were allocated and 2216 valid questionnaires were recovered,with an effective recovery rate of 97.71%.The respondents included 1199 boys(54.11%)and 1017 girls(45.89%).The frequency of liquid dairy product intake was(6.41±4.86)times per week,and the median intake amount was 1250.00 g per week(interquartile range,1750.00 g per week).There were 607 students(27.39%)consuming liquid dairy products of 2100 g and greater a week,and 1016 students(45.85%)consumed liquid dairy products for 7 times and more a week.Multivariable logistic regression analysis showed that living in urban areas(OR=1.204,95%CI:1.005-1.443),knowing nutrition labels(OR=1.221,95%CI:1.021-1.460),periodical measurement of body weight(OR=1.486,95%CI:1.098-2.011)and restricted intake of sugar-containing drinks(OR=1.264,95%CI:1.005-1.590)facilitated the intake of liquid dairy products for 7 times and more a week,and students with periodical measurement of body weight were more likely to consume liquid dairy products for 2100 g and greater a week(OR=1.821,95%CI:1.240-2.676).Conclusions Inadequate intake of liquid dairy products is found among the fourth grade students in Nanjing City.Residence,awareness of nutrition labels,periodical measurement of body weight,and parental restriction of sugar-con
