| Popis: | Body mass index (BMI) correlates with clinical outcomes in cystic fibrosis but has limitations. Body composition aberrations in CF are multifactorial. We sought to evaluate body composition and relationships with pulmonary function, bone health, and hospital admissions. Other aims included defining body composition indices in a cohort of children with CF.We conducted a retrospective review of patients with CF, age 8-18 years, seen at Nationwide Children's Hospital (2015-2020). Indices of body composition measured by dual-energy x-ray absorptiometry(DXA) scans. Data included fat mass, fat-free mass (FFM), forced expiratory volume in one second (FEV1%), bone mineral density (BMD), and hospital admissions. NWA was defined as BMI 5T-tests compared NWA, FFMD and clinical measurements. Pearson correlations analyzed fat-free mass index (FFMI), fat mass index (FMI), BMI and clinical measurements.This study included 114 patients. Mean age 12 years, 72 female. A high prevalence of FFMD existed (n=66, 38.6%). FMI and FFMI correlated with FEV1% (r: 0.23, p:0.01, r: 0.36, p0.001, respectively) and BMD (r: 0.29, p:0.002). FMI and hospital admissions were related (r:-0.23,p:0.01). FFMD was associated with 9.5% lower FEV1% (p=0.001) and lower BMD Z-score by 1.1 (p0.001) when compared to no FFMD.This cohort of children with CF had a high prevalence of FFMD and low prevalence of NWA. FFMD was associated with worsened clinical measurements. Patients with FFMD need additional exercise or nutritional intervention. Heterogeneity of body composition definitions creates need for more research. |
