Plain language summary
Fragility fractures are associated with both personal and healthcare system burdens. It is well established that bone loss leading to osteopenia or osteoporosis results in increased risk of fractures. Prescription of pharmacological agents is commonly used as first-line treatment. The aim of this study was to evaluate the effect of the Osteo-cise: Strong Bones for Life program on the patient-reported outcomes including health related quality of life (HRQoL), osteoporosis knowledge and osteoporosis attitudes and beliefs. This study is a secondary analysis of an 18-month randomised controlled trial in which participants were randomly allocated to either the community-based Osteo-cise: Strong Bones for Life program (‘Osteo-cise’) or a standard care control group. Results showed that there were no significant effects on HRQoL, osteoporosis knowledge or osteoporosis attitudes and beliefs compared with usual care. However, per protocol analyses revealed that those most adherent to exercise training did experience significant improvements in both HRQoL and osteoporosis knowledge compared with usual care. Authors concluded that their findings highlight the need to identify strategies that promote long-term adherence to multifaceted exercise programs in community-dwelling older adults.
Abstract
UNLABELLED This study identified that an 18-month community-based, multifaceted, exercise program consisting of resistance, weight-bearing impact, and balance/mobility training combined with osteoporosis education and behavioural support can improve health-related quality of life (HRQoL) and osteoporosis knowledge in older adults at risk of fracture, but only for those adherent to the exercise regime. PURPOSE To evaluate the effects of an 18-month community-based exercise, osteoporosis education and behaviour change program (Osteo-cise: Strong Bones for Life) on HRQoL, osteoporosis knowledge and osteoporosis health beliefs. METHODS This was a secondary analysis of an 18-month randomised controlled trial in which 162 older adults aged ≥ 60 years with osteopenia or increased falls/fracture risk were randomized to the Osteo-cise program (n = 81) or control group (n = 81). The program consisted of progressive resistance, weight-bearing impact and balance training (3 days/week); osteoporosis education to facilitate self-management of musculoskeletal health and behavioural support to enhance adherence to exercise. HRQoL, osteoporosis knowledge and osteoporosis health beliefs were assessed using the EuroQoL questionnaire (EQ-5D-3L), Osteoporosis Knowledge Assessment Tool and Osteoporosis Health Belief Scale, respectively. RESULTS Overall, 148 participants (91%) completed the trial. Mean exercise adherence was 55% and mean attendance for the three osteoporosis educational sessions ranged from 63-82%. After 12 and 18 months, there were no significant effects of the Osteo-cise program on HRQoL, osteoporosis knowledge or health beliefs relative to controls. Per protocol analyses (≥ 66% exercise adherence; n = 41) revealed a significant net benefit in EQ-5D-3L utility for the Osteo-cise group relative to controls after 12 months (P = 0.024) and 18 months (P = 0.029) and a significant net improvement in osteoporosis knowledge scores at 18 months (P = 0.014). CONCLUSION This study supports the importance of adherence to exercise regimes, as adherence to the Osteo-cise: Strong Bones for Life program was associated with improvements in HRQoL and osteoporosis knowledge in older adults at increased risk for falls and fractures.
