摘　　要：目的调查张家口地区不同人群对n-3多不饱和脂肪酸(n-3 PUFAs)膳食的知信行现状,并分析其影响因素,为n-3 PUFAs的膳食推荐及相关健康教育提供参考。方法利用分层随机抽样法,选取2022年8月—2023年8月张家口市6个区县的330人作为调查对象,自行设计调查问卷,内容包括一般资料及n-3 PUFAs知识、态度、行为问卷。采用方差分析、t检验分析不同特征人群知信行总分差异,采用多元逐步线性回归分析调查对象知信行总分的影响因素。结果调查对象n-3 PUFAs膳食知信行总分为(74.36±23.51)分,知识维度得分为(27.12±8.98)分,态度维度得分为(26.82±9.66)分,行为维度得分为(20.42±7.82)分。不同年龄段、婚姻状态、居住地、教育程度及月收入水平的调查对象n-3 PUFAs膳食知信行总分差异均有统计学意义(P<0.05),其中45~59岁、已婚、居住在城镇、教育程度为高中及以上,以及月收入>6000元的人群知信行总分较高。多元逐步线性回归分析结果显示,教育程度、收入水平、婚姻状况及居住地是调查对象n-3 PUFAs膳食知信行总分的主要影响因素(P<0.05)。Pearson相关分析结果提示,知识、态度与行为三者间均呈正相关(P<0.05)。结论张家口地区部分人群的n-3 PUFAs知识、态度和行为水平较差,对n-3 PUFAs膳食营养的知识掌握一般,行为情况不容乐观。要特别关注教育水平较低、收入较低、未婚群体和农村居民,针对人员不同特点因地制宜地开展宣传及教育。Objective To investigate the current status of knowledge,attitude,and practice(KAP)regarding the dietary intake of n-3 polyunsaturated fatty acids(n-3 PUFAs)among different populations in Zhangjiakou,and to analyze the influencing factors,provi-ding a reference for dietary recommendations and related health education on n-3 PUFAs.Methods A stratified random sampling method was used to select 330 individuals from six districts and counties in Zhangjiakou from August 2022 to August 2023 as survey participants.A self-designed questionnaire was used,which included general information and a KAP questionnaire on n-3 PUFAs.A-nalysis of variance and t-tests were used to analyze differences in the total KAP scores between groups with different characteristics.Multivariate stepwise linear regression analysis was employed to identify the factors influencing the total KAP scores.Results The to-tal KAP score of n-3 PUFAs diet in the survey participants was(74.36±23.51)points,with the knowledge dimension scoring(27.12±8.98)points,the attitude dimension scoring(26.82±9.66)points,and the behavior dimension scoring(20.42±7.82)points.Significant differences were noted in the total KAP scores among different age groups,marital status,residential areas,education levels,and monthly income levels(P<0.05).The groups with higher total KAP scores were those aged 45-59,married,living in urban areas,with a high school education or above,and with a monthly income greater than 6000 RMB.Multivariate stepwise linear regression analysis showed that education level,income level,marital status,and residential area were the main influencing factors for the total KAP score of n-3 PUFAs diet(P<0.05).Pearson correlation analysis indicated positive correlations between knowledge,attitude,and behavior(P<0.05).Conclusion Some populations in Zhangjiakou have poor KAP regarding n-3 PUFAs,with general knowledge of n-3 PUFAs diet nutrition and less optimistic practice.Special attention should be given to groups with lower education levels,lower income,u
