To investigate the influence of food insecurity on women's stress, disordered eating, dietary fat intake, and weight during the postpartum period.
The association between marginal food security and food insecurity-measured during pregnancy and postpartum-and stress, disordered eating, dietary fat intake, and weight at 3 and 12 months postpartum was estimated using multivariate linear regression, controlling for demographic and socioeconomic characteristics and health behaviors. Effect modification between level of food insecurity and prepregnancy weight status was assessed, hypothesizing a stronger association would be found among women who started pregnancy with overweight or obesity.
Food insecurity status during pregnancy was strongly associated with higher levels of stress, disordered eating, and dietary fat intake at 3 and 12 months postpartum; during the postpartum period, food insecurity was associated with these measures at 12 months postpartum. A significant interaction was found between level of food insecurity and prepregnancy weight status; food insecurity was associated with greater weight and BMI at 12 months only among women with overweight or obesity.
In order to return to one's prepregnancy weight, women with overweight and obesity who face household food insecurity may need multipronged assistance that not only addresses having enough high-quality food, but also include stress reduction and eating behavior interventions.
探讨粮食不安全对产后女性压力、饮食失调、膳食脂肪摄入量及体重的影响。
采用多元线性回归估计孕期和产后测量的边缘粮食安全与粮食不安全与产后3个月和12个月时的压力、饮食失调、膳食脂肪摄入量及体重之间的关联，并对人口统计学、社会经济特征及健康行为进行控制。评估粮食不安全水平与孕前体重状况之间的效应修饰，假设在超重或肥胖状态下开始妊娠的女性中会发现更强的关联。
孕期的粮食不安全状况与产后3个月和12个月时更高水平的压力、饮食失调及膳食脂肪摄入量密切相关；在产后阶段，粮食不安全与产后12个月时的这些指标相关。在粮食不安全水平与孕前体重状况之间发现了显著的交互作用；仅在超重或肥胖的女性中，粮食不安全与产后12个月时更大的体重和体重指数相关。
为了恢复到孕前体重，面临家庭粮食不安全的超重和肥胖女性可能需要多方面的援助，这不仅要解决获得足够优质食物的问题，还应包括减轻压力和饮食行为干预。
