背景：为人父母是一个重大的生活事件，可能会影响父母的个人生活方式，但缺乏基于理论的研究来检验为人父母对饮食行为动机的影响。因此，我们没有意识到社会认知变量可以预测那些即将为人父母的人的饮食行为。这项研究的目的是在计划行为理论（TPB）的框架下，研究12个月内的饮食行为动机，并将这些动机在新父母、非父母和已为人父母的人群中进行比较。方法：非父母（n = 92）、新父母（n = 135）和已为人父母（n = 71）完成TPB问卷，评估态度、主观规范、感知行为控制（PBC）和意图，以及基线时、产后6个月和12个月（父母）和产后6个月和12个月（非父母）的三天饮食记录。结果：重复测量方差分析显示，在男性中，新父母和新父母比非父母有更大的健康饮食意愿，F(2) = 3.59, p = 0.03。在女性中，已成家的父母比新父母和未成家的父母有更大的意愿，F(2) = 5.33, p = 0.01。在产后6个月的男性和女性中，新父母的PBC下降，而已成年父母的PBC增加。总体而言，情感态度是男性（β = 0.55, p < .001）和女性（β = 0.38, p < .01）意图的最强预测因子。PBC预测了男性水果和蔬菜消费量的变化（β = 0.45, p = 0.02），以及男性（β = -0.25, p = 0.03）和女性（β = - 0.24, p < 0.05）脂肪消费量的变化，而与父母身份无关。结论：初为父母和已为人父母的过渡可能会影响健康饮食的动机，尤其是在TPB框架下的PBC。然而，无论父母身份如何，情感态度和PBC都是意图和饮食行为的关键前提。干预应
Background: Transitioning to parenthood is a major life event that may impact parents' personal lifestyles, yet there is an absence of theory-based research examining the impact of parenthood on motives for dietary behaviour. As a result, we are unaware of the social cognitive variables that predict eating behaviour among those transitioning to parenthood. The purpose of the study was to examine eating behaviour motives across 12 months within the framework of the theory of planned behavior (TPB) and compare these across groups of new parents, non-parents, and established parents.Methods: Non-parents (n = 92), new parents (n = 135), and established parents (n = 71) completed TPB questionnaires assessing attitudes, subjective norms, perceived behavioral control (PBC), and intentions and three day food records at baseline, and 6- and 12-months post-delivery (for parents) and 6- and 12-months post-baseline (for non-parents).Results: Repeated measures ANOVAs revealed that among men, new-and established-parents had greater intentions to eat healthy compared to non-parents, F(2) = 3.59, p = .03. Among women, established parents had greater intentions than new-and non-parents, F(2) = 5.33, p = .01. Among both men and women during the first 6-months post-delivery, new-parents experienced decreased PBC, whereas established parents experienced increased PBC. Overall, affective attitudes were the strongest predictor of intentions for men (beta = 0.55, p < .001) and women (beta = 0.38, p < .01). PBC predicted changes in fruit and vegetable consumption for men (beta = 0.45, p = .02), and changes in fat consumption for men (beta = -0.25, p = .03) and women (beta = -.24, p < .05), regardless of parent status.Conclusion: The transition to parenthood for new and established parents may impact motivation for healthy eating, especially PBC within the framework of TPB. However, regardless of parental status, affective attitudes and PBC are critical antecedents of intentions and eating behaviour. Interventions should
