Takeaway

  • Physical activity (PA) is positively associated with bone mineral density (BMD) in paediatric patients with IBD.

Why this matters

  • Some 8% to 65% of children and adolescents with IBD have low BMD, say researchers.
  • For these patients, it is a "powerful predictor" of fracture risk, they say.

Study design

  • Researchers studied paediatric patients with IBD (N=84, 45 boys; mean age, 14.3±2.7 years), measuring BMD, physical activity (PA), and QoL.
  • Funding: Lille University Hospital Programme.

Key results

  • Mean BMD Z-score was −0.96±1.11; 51% had osteopenia, 4% had osteoporosis.
  • After adjusting for pubertal status and BMI, PA was positively associated with BMD (regression coefficient per 1 standard deviation increase in PA parameters, 0.26; P<.05>
  • PA was not associated with QoL.

Limitations

  • The study was observational, with a small sample size, and did not show causality.
  • It did not account for type of PA or disease severity.
