Physical activity before and after primary total hip arthroplasty: a registry-based study.

Objective: Detailed assessment of activity before and after total hip arthroplasty (THA) including a long-term followup period is lacking. Our objectives were to evaluate patient activity levels prior to disease onset, prior to THA, and at 5 and 10 years after surgery, and to determine the predictors of high activity 5 years after surgery.

Methods: We included elective primary THAs performed between 1996 and 2012.

Children with oligoarticular juvenile idiopathic arthritis are at considerable risk for growth retardation.

Objective: To assess linear growth in patients with persistent oligoarticular juvenile idiopathic arthritis (JIA) treated by intra-articular corticosteroid injections (IACSI).

Study Design: Data were obtained from a retrospective review of the charts of 95 patients with persistent oligoarticular JIA (69 females). The mean age at first visit was 4.

Physical activity levels and determinants of change in young adults: a longitudinal panel study.

Background: There is growing concern about physical inactivity in adolescents and young adults. Identifying determinants that are associated with low levels of physical activity and with changes in physical activity levels will help to develop specific prevention strategies. The present study describes the prevalence and potential determinants of physical activity behavior and behavior changes of young adults.
