Malnutrition and decreased food intake at diagnosis are associated with hospitalization and mortality of idiopathic pulmonary fibrosis patients

International audience; INTRODUCTION AND AIMS: Malnutrition is frequent in patients with idiopathic pulmonary fibrosis (IPF). We examined the relationship between malnutrition at diagnosis and all-cause hospitalization, survival, and acute exacerbation in newly diagnosed IPF patients. METHODS: In this prospective cohort study, the nutritional status of 153 consecutive newly-diagnosed IPF outpatients was evaluated by measuring body mass index (BMI), fat-free mass index (FFMI) with bioelectrical impedance analysis, and food intake with the Self Evaluation of Food Intake (SEFI)®. Diagnosis was taken as the baseline date and malnutrition was defined as an FFMI below 17 (men) or 15 kg/m(2) (women). To determine the factors associated with all-cause hospitalization and mortality, univariate Cox regression analyses were performed and variables with P
