Background: Bronchiectasis is a major contributor to respiratory morbidity and healthcare utilization in children. Children with bronchiectasis exhibit low levels of physical activity (PA) and poor fundamental movement skills (FMS) may be a contributing factor. However, there are no data on FMS’s in this patient group. The current study assessed FMS proficiency in children with bronchiectasis and examined associations with objectively measured PA.
Methods: Forty-six children with bronchiectasis (mean age 7.5 ± 2.6 y) were recruited from the Queensland Children’s Hospital, Brisbane. Daily time spent in sedentary activities, light-intensity activities and games, walking, running, and moderate-to-vigorous activities and games was measured objectively using the ActiGraph GT3X+ accelerometer. The raw accelerometer data were processed into PA metrics using a random forest PA classification algorithm specifically developed for children. FMS were assessed using the Test of Gross Motor Development 2nd Edition (TGMD-2).
Results: Fewer than 5% of children demonstrated mastery in the run, gallop, hop, and leap; while fewer than 10% demonstrated mastery for the two-handed strike, overarm throw, and underarm throw. The mean Gross Motor Quotient of 82.7 ± 12.8 indicated that, as a group, FMS performance was well below average.Only eight of the 46 children (17.4%) achieved their age equivalency for locomotor skills, while just four (8.7%) achieved their age equivalency for object control skills. Children achieving their age equivalency for FMS exhibited significantly higher levels of PA than children not achieving their age equivalency (51.7 vs 36.7 min/day). When examined by the five activity classes predicted by the random forest PA classification algorithm, children achieving their age equivalency exhibited significantly greater participation moderate-to-vigorous intensity activities and games (22.1 vs 10.7 min/day). No significant differences were observed for sedentary activities, light-intensity activities and games, walking, and running.
Conclusion: Children with bronchiectasis exhibit significant delays in their FMS development. However, those who meet their age equivalency for FMS proficiency participate in significantly more daily MVPA than children who do not meet their age-equivalency. Therapeutic exercise programs designed to improve FMS proficiency are thus likely to be beneficial in this patient group.
