Clinical and anthropometric evolution of individuals with cystic fibrosis during COVID-19 pandemic: A 24-month cohort study.

Objectives: To analyze the evolution of clinical and anthropometric characteristics of children and adolescents with cystic fibrosis (CF) over 24 months, including the period of the COVID-19 pandemic.

Methods: A longitudinal study with data collection from May 2018 to November 2020 in physical and electronic records from a pediatric reference center, including individuals with CF aged up to 18 years.

Results: The sample encompassed 72 individuals.

Heart rate variability, exercise capacity and levels of daily physical activity in children and adolescents with mild-to-moderate cystic fibrosis.

Background: Autonomic nervous system balance is altered in cystic fibrosis (CF), although its influence on physical fitness has been poorly explored.

Objective: This study aimed to evaluate the association of heart rate variability (HRV) with exercise capacity and levels of daily physical activity in children and adolescents with mild-to-moderate CF.

Methods: A cross-sectional study including individuals with CF aged 6-18 years, not under CFTR modulator therapy, was performed.

Association of sleep disorders with heart rate variability in children and adolescents with cystic fibrosis.

Objective: To assess the association of sleep disorders with the findings of heart rate variability (HRV) in children and adolescents with cystic fibrosis (CF).

Methods: Cross-sectional study including children and adolescents aged six to 18 years with a clinical diagnosis of CF. Sociodemographic and clinical data were collected.

Sleep disorders are distinctively associated with exercise intolerance and sedentary behavior in children with cystic fibrosis.

Objective: To evaluate the presence of sleep disorders and its associations with exercise capacity and daily physical activity levels among children and adolescents with CF.

Methods: Children age 6-18 years with a diagnosis of CF were recruited. Information regarding sociodemographic profile, pulmonary function and nutritional status were collected.
