Objective: To establish the nutrition literacy core items for Chinese lactating women. Methods: The framework system and preliminary items of nutrition literacy were established through literature review and experts consultation. E-Delphi method was used to determine the nutrition literacy items. 11 experts in the field of maternal and child nutrition, obstetrics and gynecology, health education and nutrition and diseases were invited to score the importance of each nutrition literacy item via Email. The judgment basis and familiarity of experts towards the items, active coefficient, authority coefficient and harmony coefficient were evaluated and analyzed to generate the final list of nutrition literacy items. Results: The active coefficients of consultation in two rounds were 81.8% (9/11) and 87.5% (8/9). The authority coefficients were (0.86±0.11) and (0.85±0.06). The average scores of importance were (4.03±1.24) and (4.64±0.50)and the harmony coefficients were 0.556 (χ²=163.42, P<0.001) and 0.40 (χ²=64.41, P<0.001). After the second round of consultation, all selected items met the inclusion criteria. We identified the final list of nutrition literacy items consisting of 3 scales (basic knowledge and concept, lifestyles and dietary behaviors, and basic skills), 10 subscales (basic nutrition concept, food and nutrition knowledge, feeding knowledge, lifestyles, dietary behaviors, feeding behaviors, weight management, complementary food production, acquisition, understanding and application of nutrition information, judgement of nutrition information, and nutrition decision making) with 24 items in total. Conclusions: The framework system and core items of nutrition literacy were established for Chinese lactating women based on E-Delphi method. The experts involved in the consultation process presented a performance with good representativeness, enthusiasm and authority. All experts' opinions are coordinated and unified, which could satisfy the demand of developing nutrition literacy core items for target population.
目的： 建立中国哺乳期妇女营养素养核心条目。 方法： 通过文献检索和专家讨论，确定哺乳期妇女营养素养框架体系，并初步制定营养素养的条目清单。采用德尔菲法确定哺乳期妇女营养素养核心条目，邀请11名妇幼营养、妇产科学、健康教育、营养与疾病等领域的专家，采用邮件的方式发放咨询问卷11份，要求专家对各个素养条目的重要性进行评分；并对专家的判断依据及对条目内容的熟悉程度进行评价，分析专家积极程度、权威程度、专家意见的集中程度及协调程度，并最终确定入选条目。 结果： 两轮德尔菲法专家的积极系数分别为81.8%（9/11）和87.5%（8/9），权威程度分别为（0.86±0.11）和（0.85±0.06）分；营养素养条目重要性得分分别为（4.03±1.24）和（4.64±0.50）分；Kendall′s W协调系数分别为0.556（χ²=163.42，P<0.001）和0.400（χ²=64.41，P<0.001）。第2轮咨询结束后，条目均在纳入标准范围内，最终入选3个维度（基本知识与理念、生活方式与饮食行为、基本技能）、10个主题（基本营养理念、食物与营养知识、喂养知识、生活方式、饮食行为、喂养行为、体重管理、辅食制作、营养信息的获取、信息识别与营养决策），共计24个条目。 结论： 通过德尔菲法建立中国哺乳期妇女营养素养核心条目，入选专家代表性好，积极性、权威程度高，专家意见集中程度及协调程度好，均达到了相关要求。.
