🚨In this new systematic review in BMJ JECH, most of the 18 studies reported dynamic associations between lifecourse socioeconomic change and dementia risk. Highest risk for those born poor who stay poor.

What evidence do we have on the Social Determinants of Dementia (SDOD)?

Delighted that this scoping review, a year or so in the making, is now published in @alzdemjournals.bsky.social. Expertly led by Anouk Geraets, we identified...

Issue with PAFs for dementia are that we could never actually achieve risk factor eradication

So, in 🇳🇿 , Etu Ma'u has led modelling of 15-25% reductions in risk factors (still ambitious) and shown meaningful PIFs over time, esp for Maori and Pacific peoples

By comparing against our previous work on what population-level, low-agency interventions are effective at lowering dementia risk factors (see: doi.org/10.1016/j.ec...) we make 4 recommendations for new policies, and 7 recommendations for policies that could be strengthened

We find a general balance across reach and agency (see figure).

But with reports of a trend towards individual-level and high-agency interventions (see: health.org.uk/reports-and-...).

A couple of months ago in @bmj.com (I’m that far behind!).

This is something we should care about. We need a medical workforce that is diverse and who can relate to patients and others in the MDT.

In this Chinese population-based sample, we found that health behaviours were more strongly linked to living longer without getting dementia, compared to APOE e4 genotype. Though we didn't see any compression of the dementia morbidity (once it occurred)

In this relatively affluent sample, social support seemed to mitigate SDOH relationship with dementia for men but not women

Is 'Precision Public Health' an oxymoron? A poster I prepared for the recent @cph.bsky.social 2024 showcase event

Stimulating day at @cph.bsky.social showcase event today on ‘Precision Public Health’*, including a great keynote from Frank Kee.

*on balance, I still think it’s an oxymoron, but plenty of food for thought!
