Our new study finds a strong association between voting in elections and subsequent mortality risk. Not formally open access, unfortunately but the publisher has generously made this (temporarily?) free to read! doi.org/10.1136/jech...

@pophel.bsky.social members @hlaht.bsky.social, Isa Yang, Lasse Tarkiainen and Pekka Martikainen published apparently the first population-based individual-level survival analysis assessing to what extent voting in an election predicts future mortality. It strongly does. doi.org/10.1136/jech...

✝️ Our study found: While religion may help those raised in difficult family environments to cope, it cannot fully offset the health risks associated with childhood adversity (e.g,parental mental health issues). @pophel.bsky.social @helsinki.fi @share-eric.bsky.social www.helsinki.fi/en/news/fair...
