Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.
We read with interest the recent study by Sabia et al. showing that adherence to Life’s Simple 7 ideal cardiovascular health recommendations in midlife (age 50 years) was associated with a lower dementia risk in later life, with a 1 point increment in the cardiovascular health score being associated with an 11% reduction in dementia risk. Our similar analysis (2018), provides evidence that adherence to Life’s Simple 7 ideal cardiovascular health recommendations  at ages 60 to 69 years was also associated with a lower dementia risk.
Specifically, we examined the cardiovascular health profiles of 60 to 69 year olds at baseline with the incidence of a number of ageing outcomes, in two large cohorts in the UK, over a maximum follow-up of 10 years. Comparable to Sabia’s study, we found a 33% reduction in risk of incident hospital diagnosed dementia in those with ideal compared to low cardiovascular risks in 181,820 healthy volunteers from the UK Biobank. These combined findings highlight that public health interventions to improve cardiovascular health are likely to be beneficial in terms of dementia risk reduction both in midlife and also in older age groups.
