This project developed computer models to estimate the value for money of interventions for cardiovascular diseases and dementia, and the impact these interventions on healthcare demand.

In this project SPHR researchers aimed to improve evidence on cardiovascular risk factors in later life to help people age well. Some scientists have claimed heart disease risk factors are not predictive in later life: for example there has been substantial publicity about how being overweight or obese in old age may even be beneficial.
To carry out this project researchers used very large databases of electronic medical records and data from study volunteers.
The research team found the idea that obesity in old age resulted in better health outcomes to be misleading as this is only true when compared to smokers and individuals with diseases causing weight loss.
Researchers found this statement to be driven in part by the BMI formula, which ignores weight gain in the stomach area, and does not consider muscle loss seen in later life. Research findings also highlighted a link between obesity and dementia.
Overall, for ageing well, researchers found having a normal BMI and waist circumference is associated with substantially better outcomes compared to older groups who are overweight.
This project was the first to look at long term trends in blood pressure towards the end of life. The findings have major potential implications for blood pressure management as researchers found individuals have a greater chance of developing high blood pressure in later life if they have substantial falls in pressures for approximately 15 years before death.
Research currently states cardiovascular disease risk factors are not predicable in later life, however the research team found 60 to 69 year olds who have good cardiovascular health are likely to be healthier for 10 years longer than those with poor cardiovascular health.
Unfortunately less than 3% of the general older population in England have ideal cardiovascular health, which showcases the extent ageing outcomes need to be improved in the older population.
