To explore the status quo and influencing factors of feeding behaviors of micronutrient powders (MNP), or yingyangbao in Pinyin, the Chinese Romanization system, of baby caregivers in remote rural areas of Sichuan Province.
In 2019, caregivers of babies aged 6 to 24 months from 6 counties of Sichuan Province were selected as the respondents of the survey through a multistage cluster random sampling method. Data concerning the baby caregivers' attitude of behavior, subjective norms, behavioral intention, and feeding behaviors about MNP feeding were collected with a questionnaire through a structured interview. Based on the theory of reasoned action, a structural equation model was constructed to explore the influencing factors of feeding behaviors.
A total of 1002 valid samples were included in the study. The effective feeding rate of MNP among the baby caregivers was 55.49%. The results of model analysis suggested that attitude of behavior ( =0.212, 95% : 0.105-0.327), subjective norm ( =0.123, 95% : 0.016-0.228), and behavioral intention ( =0.162, 95% : 0.093-0.224) could have a significant direct impact on MNP feeding behaviors. Behavior attitude ( =0.044, 95% : 0.023-0.073) and subjective norms ( =0.018, 95% : 0.001-0.040) could have a significant indirect impact on MNP feeding behaviors through the intermediary of behavioral intention. Among the three theoretical elements, attitude of behavior had the largest total effect on the feeding behavior ( =0.256, 95% : 0.148-0.366).
The effective feeding rate of MNP among baby caregivers in remote rural areas of Sichuan Province is low. The attitude of behavior and subjective norms of caregivers may have a direct impact on their feeding behavior, and both attitude of behavior and subjective norms can have an indirect impact on the feeding behavior through the intermediary of behavioral intention. The influence of attitude of behavior attitude on feeding behavior is greater than that of subjective norms. Future intervention plans for promoting effective MNP feeding should incorporate health education for baby caregivers and their important social relations. Thus, baby caregivers' attitude and willingness for MNP feeding will be strengthened and the effective feeding rate of MNP will be improved accordingly.
探讨四川省偏远农村地区婴幼儿照料者对 micronutrient powders（MNP，拼音为“营养包”）的喂养行为现状及影响因素。
2019年，通过多阶段整群随机抽样方法，选取四川省6个县6至24月龄婴幼儿的照料者作为调查对象。采用问卷调查结合结构化访谈的方式，收集婴幼儿照料者关于MNP喂养的行为态度、主观规范、行为意向及喂养行为等方面的数据。基于合理行动理论构建结构方程模型，探讨喂养行为的影响因素。
本研究共纳入1002份有效样本。婴幼儿照料者中MNP的有效喂养率为55.49%。模型分析结果显示，行为态度（β =0.212，95%CI：0.105 - 0.327）、主观规范（β =0.123，95%CI：0.016 - 0.228）和行为意向（β =0.162，95%CI：0.093 - 0.224）对MNP喂养行为有显著直接影响。行为态度（β =0.044，95%CI：0.023 - 0.073）和主观规范（β =0.018，95%CI：0.001 - 0.040）可通过行为意向的中介作用对MNP喂养行为产生显著间接影响。在三个理论要素中，行为态度对喂养行为的总效应最大（β =0.256，95%CI：0.148 - 0.366）。
四川省偏远农村地区婴幼儿照料者中MNP的有效喂养率较低。照料者的行为态度和主观规范可能直接影响其喂养行为，且行为态度和主观规范均可通过行为意向的中介作用间接影响喂养行为。行为态度对喂养行为的影响大于主观规范。未来促进MNP有效喂养的干预计划应纳入针对婴幼儿照料者及其重要社会关系的健康教育。从而增强婴幼儿照料者对MNP喂养的态度和意愿，相应提高MNP的有效喂养率。
