- ♻️🧠Thrilled to publish my first sole-authored paper in Socail Science & Medicine. This study revealed the link of childhood indoor air pollution with later-life cognitive health and its mechanisms, using national data and a machine learning approach. @pophel.bsky.social @helsinki.fi
- 👩💻Our new paper in BMC Geriatrics shows that Internet use can 'heal' loneliness among older Chinese adults, especially married ones. Social participation & online connections partly explain this. Notably, WeChat Moments use is key for lowering loneliness. @pophel.bsky.social @helsinki.fi
- ✝️ 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...
- 📣 Our new preprint used machine learning across 30 countries to reveal key life-course social determinants of loneliness among older adults. We also developed a Streamlined Loneliness Predictive Model for future applications. @pophel.bsky.social @share-eric.bsky.social doi.org/10.1101/2025...
