Determining the relationship of diet quality with weight change, body mass index, and depression in women who had undergone sleeve gastrectomy: A cross-sectional descriptive study

Abstract

Introduction: This study aims to determine the relationship of diet quality in women with weight change, body mass index (BMI), and depression one year after undergoing sleeve gastrectomy. Material and Methods:This is a cross-sectional descriptive study with 62 women aged 18-65 years who underwent sleeve gastrectomy in a private hospital and completed their first postoperative year. The participants were asked to fill a questionnaire on 3-day food consumption record, sociodemographic characteristics, and nutritional status; beck depression inventory (BDI) was applied. Mean adequacy ratio (MAR) was used to evaluate diet quality. Results: The mean age was 33.6 +/- 9.5 years. The mean MAR score was 76.0 +/- 31.8, and the mean BDI score was 8.2 +/- 6.4. The excess weight loss rate was high in patients with good diet quality, and the BMI and depression scores were low (P-EWL,P- BMI > 0.05, P-Beck < 0.001). Diet quality was found to be negatively correlated with body weight, BMI and depression scores and positively correlated with excess weight loss. Conclusions: Enhancing the diet quality can help patients in overcoming postoperative depression and increasing the success of weight loss. Regular follow-up and guidance provided to the patients by specialized dietitians can further augment the success rates.
