It is hypothesised that the PAF intervention will be effective in increasing physical activity in older adults at risk of disability, and that the increased physical activity will lead to a reduction in disability and/or improved physical performance.Ĭriteria for proceeding to definitive trialĪn acceptable proportion of individuals respond to recruitment invitations. In summary, the PAF facilitator acts as the main agent of change and aims to address the core psychological needs of participants through face-to-face and telephone sessions. The intervention uses facilitators to deliver behaviour change techniques with motivational interviewing strategies. The PAF intervention was modified and developed for application to a population of older adults at risk of disability. Identifying a cost-effective and sustainable means of increasing physical activity in older adults therefore remains an important public health priority.Īn existing intervention, Physical Activity Facilitation, has been used successfully to increase physical activity in adults with depression. However, we know that only around half of 65–74 year olds in the UK report doing sufficient activity to meet recommended targets and physical activity levels in those aged 75 years and older are even lower. Findings from the LIFE study support the hypothesis that physical activity in later life can prevent or delay age-related disability. It is therefore important that we identify ways of enabling older people to function well and live independently as they age. In the UK in 2016, adults aged 65 years and over comprised 18% of the population and it is projected that this will increase to 25% over the next 30 years. Recent advances in medical science and public health have reduced overall premature mortality, resulting in a larger population of older adults with increasing prevalence of comorbidities. ![]()
