Abstract

Background: Over the last decades aggressive interventions have been successful to improve nutritional outcomes in people with cystic fibrosis (CF). As a result, with improvement of life expectancy and new CFTR modulators, overweight and obesity are progressively becoming a source of concern for adult population and in developed countries. Methods: This was a multicenter, observational, cross-sectional study of 321 adults with CF at three large CF centers in Italy. Patients were divided into three groups according to BMI classes, overweight and obesity (OW) group including patients with BMI ≥25 kg/m2, normal weight (NW) group with BMI 18.6–24.9 kg/m2 and underweight (UW) group with BMI ≤18.5 kg/m2. Results: We demonstrated that prevalence of OW in adults with CF in Italy is 22%. OW status is independently associated with male sex (OR 3.520, P = 0.001), pancreatic sufficiency (OR 2.873, P = 0.014) and older age at diagnosis (1.015, P = 0.042). BMI correlated with ppFEV1 (r = 0.337; P<0.0001) with median ppFEV1 significantly higher in patients with OW than comparisons. We also reported preliminary data on unfavorable cardiovascular risk factors in a subgroup of patients, where median blood levels [IQR] of cholesterol and systemic hypertension [%] were significantly higher in the OW group than in the NW and UW. Conclusions: People with CF and OW is a relevant patient group that might deserve better definition and proper clinical management.
