The study assesses the psychosocial predictors of intention to integrate biofortified pro-vitamin A orange-fleshed sweet potato (OFSP) in proper complementary feeding (PCF) among women who received either verbal or verbal and visual demonstrations on OFSP-based foods. A total of 764 randomly selected women grouped into four categories, namely pregnant women, women with infants, women with young children, and potential mothers, participated in this study. Using a structural equation model of predicted intentions based on an extended Theory of Planned Behavior (TPB) the study found goal-setting, perceived behavior control, subjective norms, and attitudes had a significant influence on intention to integrate OFSP in PCF. Unexpectedly, knowledge of the various health benefits of OFSP did not positively influence intention. Probabilistic recursive regression was then used to estimate the relationship between the intention to provide PCF practices and its potential antecedents. The results then showed that the model structure and explanatory power was information-specific and also revealing outcome differences by category of women. These results have implications on how interventions targeting the improvement of PCF should be organized and delivered. They underscore the need to segment the audience during nutrition education.
本研究评估了接受口头或口头加视觉演示的食用富含β-胡萝卜素的橙色果肉甘薯(OFSP)相关食物的妇女,其将生物强化型富维生素 A 甘薯纳入适当补充喂养(PCF)的心理社会预测因素。共有 764 名随机挑选的妇女分为四组,即孕妇、有婴儿的妇女、有幼儿的妇女和潜在的母亲,参与了这项研究。本研究采用基于扩展计划行为理论(TPB)的预测意向的结构方程模型,发现目标设定、感知行为控制、主观规范和态度对将 OFSP 纳入 PCF 的意向有显著影响。出乎意料的是,对 OFSP 的各种健康益处的了解并没有对意向产生积极影响。然后使用概率递归回归来估计提供 PCF 实践及其潜在前因之间的关系。结果表明,该模型结构和解释力具有信息特异性,并且通过妇女类别揭示了结果差异。这些结果对如何组织和提供针对改善 PCF 的干预措施具有启示意义。它们强调了在营养教育期间需要对受众进行细分。
