Compliance with dietary guidelines and relationship to psychosocial factors in low-income women in late postpartum

Objectives: 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. Design: 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. Statistical analyses performed: Descriptive statistics, analysis of variance with post-hoc Scheffe tests, χ² with follow-up tests of independent proportions, and Pearson correlation coefficients were utilized. Results: 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. Conclusions: 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.
