The purpose of this study is to compare healthy children to children who have a chronic illness called Juvenile Idiopathic Arthritis (JIA). JIA is a childhood disease that causes swollen joints that are often stiff and painful. JIA affects about 1 in 1,000 children age 16 and younger.

Primary Outcome Measures:
  • Lumbar spine volumetric Bone Mineral Density (vBMD) and vertebral size will vary according to sex, age and pubertal stage. [ Time Frame: same day ]

Secondary Outcome Measures:
  • Children with JIA will have lower vertebral stiffness and strength, compared with controls. [ Time Frame: same day ]

Biospecimen Retention:   Samples Without DNA

Enrollment: 127
Study Start Date: April 2008
Study Completion Date: June 2017
Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
No treatment

Detailed Description:
Children with chronic illnesses are at risk for bone fragility due to inflammation, glucocorticoid therapy, physical activity limitation, malnutrition, and pubertal delay. The impact of low bone mass during childhood may be immediate, resulting in childhood fractures, or delayed, due to suboptimal peak bone mass attainment.
