Sedentary Time and Screen-Based Sedentary Behaviors of Children With a Chronic Disease

Abstract

The objectives of this study were to (i) assess sedentary time and prevalence of screen-based sedentary behaviors of children with a chronic disease and (ii) compare sedentary time and prevalence of screen-based sedentary behaviors to age- and sex-matched healthy controls. Sixty-five children (aged 6-18 years) with a chronic disease participated: survivors of a brain tumor, hemophilia, type 1 diabetes mellitus, juvenile idiopathic arthritis, cystic fibrosis, and Crohn's disease. Twenty-nine of these participants were compared with age- and sex-matched healthy controls. Sedentary time was measured objectively by an ActiGraph GT1M or GT3× accelerometer worn for 7 consecutive days and defined as less than 100 counts per min. A questionnaire was used to assess screen-based sedentary behaviors. Children with a chronic disease engaged in an average of 10.2 ± 1.4 hr of sedentary time per day, which comprised 76.5 ± 7.1% of average daily monitoring time. There were no differences between children with a chronic disease and controls in sedentary time (adjusted for wear time, p = .06) or in the prevalence of TV watching, and computer or video game usage for varying durations (p = .78, p = .39 and, p = .32 respectively). Children with a chronic disease, though relatively healthy, accumulate high levels of sedentary time, similar to those of their healthy peers.

Clinical impact of sedentary behaviors in adult survivors of acute lymphoblastic leukemia: A report from the St. Jude Lifetime Cohort study

“…22 Survivors spent more time per day in sedentary behavior than reported in the general population (66% vs 60%, respectively), 6 but less than that reported by Walker et al among young children/adolescents with chronic diseases, including survivors of brain tumors (66% vs 77%, respectively). 23 In contrast to the results of the current study, Walker et al found no differences between survivors and controls; however, the comparison sample size was small (29 participants), heterogeneous in terms of disease, and based on a much younger population. Increased screen time and sedentary behavior were found to be associated with a lower percentage lean mass, with a similar association described in communitydwelling older adults.…”

Dipeptide repeat proteins inhibit homology-directed DNA double strand break repair in C9ORF72 ALS/FTD

“…This suggests that epigenetic repression of the C9ORF72 promoter leading to reduced transcription and DPR production likely accounts for the reduced levels of DNA DSB markers in C9ALS-2 iMNs. Epigenetic repression of the C9ORF72 locus has been shown to alter C9ORF72 RNA splicing, DPR production and features of the C9ALS/FTD clinical presentation [60][61][62]. While based on only two cell lines, our results suggest C9ORF72 promoter hypermethylation alters DNA damage phenotypes in C9ALS iPSC neurons as well.…”

Measuring activities and participation in persons with haemophilia: A systematic review of commonly used instruments

“…Five studies reported on accelerometers; 4 only included children, one only adults . One study explicitly aimed to validate an accelerometer (Actiheart, uniaxial accelerometer combined with heartrate) for the measurement of energy expenditure in children with different chronic diseases.…”
