尽管怀孕期间健康饮食的动机很高，但产妇的饮食质量不足。在怀孕期间，女性可能会放松对饮食的控制以减轻压力;因此，压力可能会压倒健康饮食的动机。对妊娠饮食属性研究纵向队列数据的二次分析调查了妊娠期间（n = 365）和产后（n = 266）健康饮食的动机和感知压力与饮食质量的关联，并调查了压力是否会改变动机与饮食质量的关联。从北卡罗来纳州的查佩尔山招募女性（法师= 31.3;胎龄≤ 12周），完成多次24小时饮食回忆（妊娠期每三个月一次，产后4-6周，6个月和1年），并验证感知压力和健康饮食动机（自主和控制）的测量。分层多元回归测试了饮食质量（健康饮食指数-2015）与压力，动机及其相互作用的关系。此外，从先前分析的焦点小组中提取的主题与参与者的子样本进行了重新检查的内容相关的压力，动机和饮食。怀孕和产后饮食质量与自主动机呈正相关，但与控制动机和压力无关。交互作用项没有明显改善模型拟合。焦点小组的参与者描述了内部和外部的力量，有助于他们在怀孕期间健康饮食的动机，并描述了压力对饮食行为的影响，通过放大食物的渴望。未来的研究需要确定对母亲健康饮食动机的影响。
Despite high motivation for healthful eating during pregnancy, maternal diet quality is inadequate. During pregnancy, women may relax effortful control over eating to reduce stress; thus, stress may override motivation to eat healthfully. This secondary analysis of data from the Pregnancy Eating Attributes Study longitudinal cohort investigated associations of motivation for healthful eating and perceived stress with diet quality during pregnancy (n = 365) and postpartum (n = 266), and investigated whether stress modifies associations of motivation with diet quality. Women (Mage = 31.3; gestational age ≤ 12 weeks) were recruited from the Chapel Hill, North Carolina area and completed multiple 24-hour diet recalls (once each trimester of pregnancy, and at 4–6 weeks, 6 months, and 1 year postpartum) and validated measures of perceived stress and motivation for healthful eating (autonomous and controlled). Hierarchical multiple regressions tested associations of diet quality (Healthy Eating Index-2015) with stress, motivation, and their interactions. Additionally, themes extracted from previously-analyzed focus groups conducted with a subsample of participants were re-examined for content relevant to stress, motivation, and diet. Pregnancy and postpartum diet quality was positively associated with autonomous motivation, but was unassociated with controlled motivation and stress. Interaction terms did not appreciably improve model fit. Focus group participants described both internal and external forces contributing to their motivation for healthy eating during pregnancy and described the impact of stress on eating behaviors through amplification of food cravings. Future research is needed to identify influences on maternal motivation for healthful eating.
