In January 2015, we commissioned an in-depth research project to try to understand the future trends for the most prevalent long-term health conditions in the UK, specifically how many people are either dying early from these conditions, or living with continued disability and poor health. We also wanted to identify interventions that could prevent or reduce the incidence of these long‑term conditions that could be applied to the whole UK population, focusing on major lifestyle risks which contribute to those conditions. The Living Longer, Living Well overview report summarises the results of this study, which used the ‘25 by 25’ goals from the World Health Organization (WHO) as a benchmark against which to measure UK trends.
