| Résumé : | [BDSP. Notice produite par INIST-CNRS mpIR0xk8. Diffusion soumise à autorisation]. Background Older people are at risk for health decline and loss of independence. Lifestyle interventions offer c potential for reducing such negative outcomes. The aim t of this study was to determine the effectiveness and s cost-effectiveness of a preventive lifestyle-based occupational therapy intervention, administered in a variety of community-based sites, in improving mental c and physical well-being and cognitive functioning in ethnically diverse older people. Methods A randomised controlled trial was conducted comparing an occupational therapy intervention and a no-treatment control condition over a 6-month experimental phase. Participants included 460 men and s women aged 60-95 years (mean age 74.9+/-7.7 years ; 53%<$12 000 annual income) recruited from 21 sites in s the greater Los Angeles metropolitan area. Results Intervention participants, relative to untreated controls, showed more favourable change scores on indices of bodily pain, vitality, social functioning, mental I health, composite mental functioning, life satisfaction and depressive symptomatology (ps<0.05). The intervention group had a significantly greater increment in quality-adjusted life years (p<0.02), which was c achieved cost-effectively (US $41 218/UK £24 868 per unit). No intervention effect was found for cognitive r functioning outcome measures. Conclusions A lifestyle-oriented occupational therapy intervention has beneficial effects for ethnically diverse s older people recruited from a wide array of community settings. Because the intervention is cost-effective and is applicable on a wide-scale basis, it has the potential to help reduce health decline and promote well-being in t older people. |
