The goals were to evaluate compliance with the Dietary Guidelines among low-income women during late postpartum and to examine the relationship between psychosocial variables and dietary compliance.
SUBJECTS/SETTING: Participants were 146 triethnic, low-income women who were recruited 0 to 1 days after childbirth and who visited a clinic site at 1 year postpartum.
At 1 year postpartum, multiple psychosocial characteristics were measured, and food choices and nutrient intakes were assessed via a validated food frequency questionnaire. Dietary guidelines index scores and measures of adherence to dietary recommendations were computed.
Descriptive statistics, analysis of variance with post-hoc Scheffe tests, chi 2 with follow-up tests of independent proportions, and Pearson correlation coefficients were utilized.
For dietary compliance, 60% had adequate intakes of meat, but less than 30% met recommendations for grains, vegetables, fruits, dairy foods, total fat, and added sugar. Healthful weights (body mass index <25) were observed in 37% of women. Those in the highest tertile of dietary compliance had a more positive body image than those in the lowest tertile, and less neglect of self-care, weight-related distress, stress, depressive symptoms, and perceived barriers to weight loss ( P <.05). Dietary compliance and psychosocial scale scores did not vary by ethnicity.
Adherence to dietary guidelines was limited in the low-income, postpartum women. Psychosocial variables, such as neglect of self-care, weight-related distress, negative body image, stress, and depressive symptoms were associated with less healthful diets and lifestyle in late postpartum. Programs that target diet-related behavior change in low-income women might be improved by inclusion of psychosocial assessment and counseling components.
目标是评估低收入女性产后晚期对膳食指南的依从性,并研究心理社会变量与饮食依从性之间的关系。
研究对象/地点:参与者为146名来自三个不同种族的低收入女性,她们在产后0至1天被招募,并在产后1年到诊所就诊。
在产后1年,测量了多种心理社会特征,并通过一份经过验证的食物频率问卷评估了食物选择和营养摄入情况。计算了膳食指南指数得分和对膳食建议的依从性测量值。
采用了描述性统计、事后Scheffe检验的方差分析、独立比例的后续检验的卡方检验以及Pearson相关系数。
在饮食依从性方面,60%的人肉类摄入量充足,但只有不到30%的人达到了谷物、蔬菜、水果、乳制品、总脂肪和添加糖的推荐摄入量。37%的女性体重健康(身体质量指数<25)。饮食依从性处于最高三分位数的女性比最低三分位数的女性身体形象更积极,自我护理的忽视、体重相关困扰、压力、抑郁症状以及减肥的感知障碍更少(P<.05)。饮食依从性和心理社会量表得分在不同种族之间没有差异。
低收入产后女性对膳食指南的依从性有限。心理社会变量,如自我护理的忽视、体重相关困扰、负面身体形象、压力和抑郁症状,与产后晚期不健康的饮食和生活方式有关。针对低收入女性与饮食相关行为改变的项目,通过纳入心理社会评估和咨询成分可能会得到改善。
