Micronutrient Powders Feeding Behaviors of Baby Caregivers in Remote Rural Areas of Sichuan Province: A Study Based on the Theory of Reasoned Action

Abstract

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 ( β direct=0.212, 95% CI: 0.105-0.327), subjective norm ( β direct=0.123, 95% CI: 0.016-0.228), and behavioral intention ( β direct=0.162, 95% CI: 0.093-0.224) could have a significant direct impact on MNP feeding behaviors. Behavior attitude ( β indirect=0.044, 95% CI: 0.023-0.073) and subjective norms ( β indirect=0.018, 95% CI: 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 ( β total=0.256, 95% CI: 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.
