摘　　要：目的以受试者工作特征曲线法(ROC曲线法),分析健康素养不同维度的拐点年龄,为提高居民健康素养提供参考。方法采用分层多阶段随机抽样方法,2021年以中国健康教育中心编制的《全国居民健康素养监测调查问卷》对自贡市15~69岁居民进行问卷调查,利用ROC曲线法分析健康素养不同维度的拐点年龄,采用二元Logistic回归验证拐点年龄对是否具备健康素养的预测效果,采用SPSS 26.0进行统计分析,检验水准α=0.05。结果本次共调查2376人,其中男性1154(48.6%)人,女性1222(51.4%)人;15~35岁共376(15.8%)人,35~45岁共297(12.5%)人,45~60岁1128(47.5%)人,60岁及以上575(24.2%)人。安全与急救素养具备率最高为55.9%,其次为健康科学观素养达34.3%,基本医疗素养26.5%,传染病防治素养13.0%,健康信息素养10.1%,慢性病防治素养最低为3.3%。健康科学观素养在不同性别人群中分布差异具有统计学意义(χ2=6.425,P=0.011),但传染病防治素养、安全与急救素养、基本医疗素养、健康信息素养以及是否具备总体健康素养在不同性别人群中分布差异并无统计学意义(P>0.05)。健康科学观素养拐点年龄为48.5岁,传染病防治素养拐点年龄为47.5岁、慢性病防治素养拐点年龄45.5岁,安全与急救素养拐点年龄53.5岁,基本医疗素养拐点年龄为51.5岁,健康信息素养拐点年龄为49.5岁,总体健康素养拐点年龄46.5岁。二元Logistic回归模型和C指数结果表明拐点年龄对健康素养转变具有预测价值。结论提高健康科学观素养应以小于拐点年龄人群为重点干预对象,提高其余维度的健康素养应以大于拐点年龄的居民为重点干预对象,从而提升总体居民健康素养水平。Objective To analyze the inflection point ages of different dimensions of health literacy by receiver operating characteristic curve(ROC curve)method,and to provide reference for improving health literacy of residents.Methods Stratified and multi-stage random sampling method was adopted.In 2021,residents aged 15-69 years in Zigong City were surveyed by the National Residents'Health Literacy Monitoring Questionnaire compiled by China Health Education Center.The inflection point ages of different dimensions of health literacy were analyzed by ROC curve method.Binary Logistic regression was used to verify the prediction effect of inflection point age on health literacy.SPSS26.0 was used for statistical analysis,and the test level wasα=0.05.Results A total of 2376 people were surveyed,including 1154(48.6%)males and 1222(51.4%)females.There were 376(15.8%)people aged 15-35 years,297(12.5%)people aged 35-45 years,1128(47.5%)people aged 45-60years,and 575(24.2%)people aged 60 and above.Safety and first aid literacy was the highest at55.9%,followed by health science literacy at 34.3%,basic medical literacy at 26.5%,infectious disease prevention and control literacy at 13.0%,health information literacy at 10.1%,and chronic disease prevention and control literacy at 3.3%.There was statistical difference in the distribution of health science literacy among different gender groups(χ^(2)=6.425,P=0.011),but there was no statistical difference in the distribution of infectious disease prevention literacy,safety and first aid literacy,basic medical literacy,health information literacy and general health literacy among different gender groups(P>0.05).The inflection point ages of health science literacy,infectious disease prevention and control literacy,chronic disease prevention and control literacy,safety and first aid literacy,basic medical literacy,health information literacy and general health literacy were48.5,47.5,45.5,53.5,51.5,49.5 and 46.5 years old,respectively.The results of binary Logistic regression model and C-ind
