Lessons from a publicly funded tier 2 healthy weight programme in Cornwall, UK.

Background The UK has one of the highest prevalence rates of obesity worldwide. Public health departments have a duty to provide some obesity treatment and prevention services. With evidence of effective programmes lacking, we investigate lessons learned from a healthy weight programme in Cornwall, UK. Methods Data from the 12-week multi-component adult healthy weight management programme were obtained for 2012–2016. Descriptive statistics and statistical tests were used to describe participants' demographics, health status and anthropometric measures to explore the enrolment and retention of the programme as well as the impact. Results A total of 1872 adults were referred into the programme. Overall, 646 completed the programme and, 48.8% achieved the programme's aim of a >3% reduction in weight. Those who completed and met the programme aim tended to have had healthier outcomes at baseline. Conclusions For those who engage with the programme the impact can be meaningful. However, <1% of the population of Cornwall with overweight or obesity enroled in the programme, and those who benefitted most might have been in least need. Providing services that meet the needs of the population is challenging when a variety of services is needed, and the evidence base is poor. [ABSTRACT FROM AUTHOR]
