目的探讨产后第一年妇女运动和食物摄入量的变化与心理社会特征之间的关系。设计一项前瞻性队列研究，随访妇女从怀孕到产后1年。在怀孕期间和产后1年，使用匿名邮寄问卷评估心理社会变量、食物摄入量变化和运动频率。从病历中获得社会人口统计学和人体测量学信息。受试者/设置622名妇女谁登记的产前护理在巴塞特医疗保健系统1994年11月7日和1996年11月15日之间，谁符合资格标准。以产后1年的运动频率和产后6个月的食物摄入量变化为因变量，产后1年的心理社会因素为自变量，控制社会人口学变量、体重，进行多元线性回归分析。结果多因素回归分析显示，运动自我效能感和运动意愿与产后1年的运动频率相关（r（2）=20%）。食物摄入自我效能、身体满意度、体重增加接受度，多变量分析显示，女性的运动量和瘦的动力都是显著的（r（2）=7%），这些变量的得分越高，食物摄入量越少。针对目标行为的有效性。例如，营养师可以通过为产后妇女提供制定现实运动目标的掌握经验来加强运动自我效能。同样，营养师可以通过模拟女性在压力情况下避免暴饮暴食的策略来关注食物摄入自我效能。
Objective To examine the relationships between psychosocial characteristics and change in exercise and food intake of women during the first year postpartum.Design A prospective cohort study following women from pregnancy until 1 year postpartum. Psychosocial variables, change in food intake, and exercise frequency were assessed using anonymous mailed questionnaires during pregnancy and at 1 year postpartum. Sociodemographic and anthropometric information was obtained from the medical record.Subjects/setting Six hundred twenty-two women who enrolled for prenatal care in the Bassett Healthcare system between November 7, 1994, and November 15, 1996, and who met the eligibility criteria. The attrition rate for completing the questionnaire at 1 year postpartum was 20%.Statistical analyses performed Multivariate linear regression with exercise frequency at 1 year postpartum and change in food intake during the second 6 months postpartum as the dependent variables and psychosocial factors assessed, at 1 year postpartum as the independent variables, controlling for sociodemographic variables, body mass. index, and gestational weight gain.Results Higher exercise self-efficacy and having the intention to exercise were associated with more frequent exercise at 1 year postpartum in the multivariate regression analysis (r(2)=20%). Food intake self-efficacy, body satisfaction, weight gain acceptance, and drive for thinness were all significant in the multivariate analysis (r(2)=7%) and higher scores on these variables were associated with reductions in food intake.Applications/conclusions Interventions that aim to help women get regular exercise and make appropriate reductions in food intake during the postpartum period should focus on self-efficacy specific to the targeted behaviors. For example, dietitians may strengthen exercise self-efficacy by providing postpartum women with mastery experiences of setting realistic exercise goals. Likewise, dietitians can focus on food intake self-efficacy by modeling strategies that women can use to avoid overeating in stressful situations.
