Nutrition and behavioral health in cystic fibrosis: Eating and body image

Abstract

AbstractPeople with CF (pwCF) are at high risk for malnutrition, making nutritional management a critical aspect of CF care. Over the past several decades, optimal nutritional status for pwCF has been defined by body mass index (BMI) based on evidence linking suboptimal BMI to decreased lung function and life expectancy, although more recent changes in CF care may also bring changes to how nutritional health is defined. The historical focus on weight, BMI, and nutrition as key parts of multidisciplinary CF care starting at an early age places pwCF at increased risk for body image concerns and disordered eating. The landscape of CF care is evolving with the approval of highly effective modulator therapies (HEMT) and resulting improvements in growth; however, issues related to body image and eating remain important to consider, especially as past difficulties gaining weight may shift to discomfort with one's weight gain and/or physical appearance. This review aims to describe how body image concerns and disordered eating occur in pwCF across the lifespan; to discuss evidence‐based approaches to addressing these concerns; and to identify future directions for research and clinical practice in assessing and treating eating disorders and body image concerns in this population.
