ABSTRACT

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.

摘要

该研究评估了在接受基于 OFSP 食物的口头或口头和视觉演示的女性中，将生物强化维生素 A 橙肉甘薯 (OFSP) 与适当的辅食 (PCF) 结合起来的心理社会预测因素。共有 764 名随机选择的女性分为四类，即孕妇、有婴儿的女性、有幼儿的女性和潜在的母亲，参与了这项研究。使用基于扩展的计划行为理论 (TPB) 的预测意图的结构方程模型，研究发现目标设定、感知行为控制、主观规范和态度对将 OFSP 整合到 PCF 的意图有显着影响。出乎意料的是，对 OFSP 的各种健康益处的了解并未对意图产生积极影响。然后使用概率递归回归来估计提供 PCF 实践的意图与其潜在前因之间的关系。结果表明，模型结构和解释力是特定于信息的，并且还揭示了女性类别的结果差异。这些结果对如何组织和实施旨在改善 PCF 的干预措施有影响。他们强调需要在营养教育期间细分受众。这些结果对如何组织和实施旨在改善 PCF 的干预措施有影响。他们强调需要在营养教育期间细分受众。这些结果对如何组织和实施旨在改善 PCF 的干预措施有影响。他们强调需要在营养教育期间细分受众。
