To understand the knowledge, attitude and practice(KAP) of nutrition label for community residents in Shanghai and the effects of health education interventions, and to explore the factors affecting the knowledge, attitude and practice(KAP), and to provide theoretical bases for relevant policies.
Using stratified random sampling to randomly select at least 20 residents before and after the intervention in each community in Shanghai. A baseline survey was carried out in early March 2016. The survey included basic information and the knowledge、attitude and practice of nutrition label. Using a combination of online and offline method such as issuing posters, folding pages, conducting lectures on knowledge, tweeting on WeChat public accounts, etc. , for a 4-month intervention, and an assessment survey was conducted in June. The same questionnaire was used before and after the intervention.
The awareness rate of nutrition labels among community residents in Shanghai increased from 63. 0% before the intervention to 87. 4% after the intervention. The proportion of those who felt it necessary to label nutrition labels increased from 77. 7% before the intervention to 88. 3%. When purchasing prepackaged food, the proportion of people who often read nutrition labels increased from 32. 2% before intervention to 51. 8%, and the above differences were statistically significant(P<0. 05). After the intervention, the mastery of nutrition labeling knowledge, attitudes and behaviors of men were positively changed(P<0. 05). After the intervention, residents in the suburban areas have significantly improved their knowledge, attitudes and behaviors related to nutrition labeling(P<0. 05). The improvement effects of residents in the suburbs was lower than that in the other two types of areas(P<0. 05). Logistic regression analysis showed that intervention, female, high education, living in the central city, knowing the nutrition label, and thinking that it is necessary to label the nutrition label are the protective factors of looking at the nutrition label when buying foods.
Health education can effectively improve the awareness rate of prepackaged food nutrition labels, relevant attitudes and behavior changes of residents in Shanghai communities. After intervention, the knowledge and behavior of nutrition labels in Shanghai communities are at a high level. Men, low-education low-income and residents in remote areas are the key population for future health education related to nutrition labels.
了解上海市社区居民对营养标签的知识、态度和行为（KAP）以及健康教育干预效果，探索影响知识、态度和行为（KAP）的因素，为相关政策提供理论依据。
采用分层随机抽样方法，在上海市各社区干预前后分别随机抽取至少20名居民。2016年3月初进行基线调查。调查内容包括基本信息以及营养标签的知识、态度和行为。采用线上线下相结合的方法，如发放海报、折页、开展知识讲座、在微信公众号发布推文等，进行为期4个月的干预，并于6月进行评估调查。干预前后使用相同问卷。
上海市社区居民对营养标签的知晓率从干预前的63.0%提高到干预后的87.4%。认为有必要标注营养标签的比例从干预前的77.7%提高到88.3%。购买预包装食品时，经常查看营养标签的人群比例从干预前的32.2%提高到51.8%，上述差异具有统计学意义（P<0.05）。干预后，男性对营养标签知识、态度和行为的掌握有正向改变（P<0.05）。干预后，郊区居民营养标签相关知识、态度和行为有显著改善（P<0.05）。郊区居民的改善效果低于其他两类地区（P<0.05）。Logistic回归分析显示，干预、女性、高学历、居住在中心城区、知晓营养标签以及认为有必要标注营养标签是购买食品时查看营养标签的保护因素。
健康教育能有效提高上海市社区居民对预包装食品营养标签的知晓率、相关态度及行为改变。干预后，上海市社区营养标签知识和行为处于较高水平。男性、低学历低收入者以及偏远地区居民是未来营养标签健康教育的重点人群。
