Motivations to eat are related to diet quality and food intake in overweight and obese, low-income women in early postpartum

Abstract

Healthful dietary practices and a return to prepregnancy weight are of significant importance in the prevention of obesity for women. The Eating Stimulus Index (ESI) was used to determine the relationship between motivations to eat and diet quality and food intake in 115 overweight/obese, low-income women in early postpartum. In this cross-sectional design, participants completed the ESI and food frequency questionnaire. Diet quality was assessed using the Dietary Guidelines Adherence Index. Diet quality was related to greater fruit and vegetable availability, convenience eating resistance, and vegetable taste preference. Women with high fruit and vegetable availability consumed more vegetables, as compared to those with low availability. High convenience eating resistance was associated with lower discretionary energy intakes. High taste preference for vegetables was related to greater intakes of these foods. Hierarchical regression analysis indicated that convenience eating resistance was the strongest predictor of diet quality followed by vegetable taste preference, and fruit and vegetable availability. Convenience eating resistance was also the strongest predictor of discretionary energy intake. In conclusion, women who were less vulnerable to environmental eating cues, had greater fruit and vegetable availability, and preferred the taste of vegetables consumed a more healthful diet. Thus, the ESI may be a useful screening tool for the design of personalized weight loss messages in the treatment of obesity.
