Associations Between Body Weight Dissatisfaction and Diet Quality in Women With a Body Mass Index in the Healthy Weight Category: Results From the 2014–2015 Swiss National Nutrition Survey

Abstract

BackgroundFew studies have examined whether diet quality is lower in women with body weight dissatisfaction compared with women without body weight dissatisfaction. Objectives(1) Examine the association between body weight dissatisfaction and diet quality among women (18–65 years old) in the healthy weight body mass index (BMI) category, and (2) explore dietary and behavioral patterns among women with body weight dissatisfaction. DesignData were extracted from the cross-sectional 2014–2015 Swiss National Nutrition Survey. Participants/settingPopulation-based sample of 507 women with BMI ≥ 18.5 and < 25. Outcome measuresDietary intakes assessed by registered dietitians using 2 nonconsecutive computer-assisted multi-pass 24-hour dietary recalls. Diet quality was measured with a slightly modified version of the Healthy Eating Index (HEI)-2020. Statistical analyses performedMultiple linear regressions were performed to test the association between body weight dissatisfaction and total HEI-2020 score. Hierarchical cluster analysis was used to identify subgroups of women with body weight dissatisfaction. ResultsBody weight dissatisfaction was not found to be associated with diet quality (β = –1.73 [–4.18; 0.71], P = .16). However, women who were dissatisfied with their body weight had lower scores for the HEI-2020 total fruits (P = .050) and whole grains (P = .014) components than women who were satisfied with their body weight. Four profiles with different dietary patterns were identified among women with body weight dissatisfaction: “Unhealthy diet with dairy,” “Protein and fat,” “Vegetables without protein,” and “Healthier diet without dairy.” ConclusionsAmong women with a BMI in the healthy weight category, overall diet quality was not observed to differ between those with or without body weight dissatisfaction. More research is needed to explore the different profiles of dietary intake in women with body weight dissatisfaction.
