目的 了解安徽省部分县区成年居民营养健康知识水平,分析其相关影响因素,为开展居民营养健康宣教及合理膳食行动提供依据。方法 于2022年5—8月采用多阶段分层整群随机抽样的方法,抽取安徽省8个县(市、区)3 392名18~64岁居民进行营养健康知识问卷调查,计算营养健康知识知晓率,并运用χ²检验和多因素logistic回归分析其影响因素。结果 2022年安徽省成年居民营养健康知识知晓率为28.1%。多因素logistic回归分析结果显示,城市居民知晓率高于农村居民(OR=1.360,95%CI=1.168~1.585);以55~64岁居民为参照,18~24岁(OR=1.844,95%CI:1.302~2.610)、25~34岁(OR=2.068,95%CI:1.657~2.582)和35~44岁(OR=1.509,95%CI:1.192~1.911)居民知晓率较高;以小学及以下文化程度为参照,初中(OR=1.347,95%CI:1.080~1.680)、高中/中专/技校(OR=2.530,95%CI:1.958~3.269)、大专/职大(OR=2.708,95%CI:2.086~3.516)、本科及以上(OR=3.484,95%CI:2.626~4.621)居民知晓率较高;以其他职业为参照,医疗卫生行业(OR=1.631,95%CI:1.096~2.425)、教育相关行业(OR=1.848,95%CI:1.242~2.750)居民知晓率较高;以<1种健康知识获取渠道为参照,获取渠道数量≥5种(OR=15.238,95%CI:1.979~117.316)居民知晓率较高。结论 安徽省部分县区成年居民的营养健康知识知晓率较低,年龄、文化程度、职业、居住地和获取健康知识渠道数量是居民营养健康知识知晓率的影响因素。

Objective To understand the level of nutritional health knowledge among adult residents in certain counties and districts of Anhui Province,and analyze its influencing factors,thus to provide a basis for nutritional health education and evaluation of rational dietary actions. Methods A multi-stage stratified cluster random sampling method was used to select 3 392 residents aged 18-64 in 8 counties (cities,districts) of Anhui Province for a questionnaire survey of nutritional health knowledge from May to August in 2022.The awareness rate of nutritional health knowledge was calculated,and the influencing factors were analyzed by using the chi-square test and multivariate logistic regression. Results In 2022,the awareness rate of nutritional health knowledge among adult residents in certain counties and districts of Anhui Province was 28.1%.The results of multivariate logistic regression analysis demonstrated that the awareness rate was higher among urban residents than that among rural residents (OR=1.360,95%CI:1.168-1.585).Compared with residents aged 55-64 years,the awareness rate was higher among those aged 18-24 (OR=1.844,95%CI:1.302-2.601),25-34 (OR=2.068,95%CI:1.657-2.582) and 35-44 (OR=1.509,95%CI:1.192-1.911).Compared with residents with education level of primary school or below,the awareness rate was higher among those with junior high school (OR=1.347,95%CI:1.080-1.680),high school/vocational/technical school (OR=2.530,95%CI:1.958-3.269),college/vocational college (OR=2.708,95%CI:2.086-3.516),and bachelor's degree or above (OR=3.484,95%CI:2.626-4.621).Compared with residents in other occupations,the awareness rate was higher among those in the medical and health industry (OR=1.631,95%CI:1.096-2.425) and education-related industries (OR=1.848,95%CI:1.242-2.750).Compared with residents who had <1 channel for obtaining health knowledge,the awareness rate was higher among those with ≥5 channels (OR=15.238,95%CI:1.979-117.316). Conclusion The awareness rate of nutritional health knowledge among adult residents in certain counties and districts of Anhui Province is relatively low.Age,education level,occupation,place of residence,and the number of channels for obtaining health knowledge are the main influencing factors.
