We're so excited to start seeing our awesome twins again when they turn 30 to better understand how their adult lives are taking shape & what their hopes and fears are for the future🤩 We'll soon be advertising for 5 researchers to help us collect this data - watch this space!👀
The Environmental Risk (E-Risk) Longitudinal Twin Study @ERiskstudy co-led by #KingsIoPPN and @kcsamh has been backed by £2.3 million funding from the @The_MRC to collect new follow-up data from #twin participants 👏 👭 Read the story ⬇️ buff.ly/3iCAuDx #IoPPNNews

Childhood victimization doesn’t define the future. Over ⅓ of affected children showed flourishing by age 18—especially in social support, sleep, and education. 💛📚 Read the paper below to find out more 📝 @KingsIoPPN @SGDPCentreKCL @The_MRC @kcsamh sciencedirect.com/science/ar…

🧠Prospective vs. retrospective measures of childhood maltreatment often flag different people. 💡More social support & better mental health → less retrospective recall 💡Higher SES & positive family functioning → harder future detection @KingsIoPPN @kcsamh @SGDPCentreKCL

🧠🌍 A recent E‑Risk finding shows a small link between higher childhood NOx exposure and later depression. No strong links for other pollutants — but clean air still matters for young people’s mental health 💙🧠 @KingsIoPPN @SGDPCentreKCL @kcsamh @The_MRC

E‑Risk twins grew up offline, entered adulthood online yet friendships stayed strong: 56% had 1–4 close friends, 40% had 5 or more. 💛🫂 @KingsIoPPN @SGDPCentreKCL @kcsamh @The_MRC

Across three cohorts, inc. @ERiskstudy a paper led by Dr Kyle Bourassa found that young people with lifetime PTSD show elevated suPAR at age 18, a marker of chronic inflammation. A key insight into how trauma shapes long‑term health. 📚✨ @The_MRC @KingsIoPPN @SGDPCentreKCL

🧠 Why do reports of childhood maltreatment change? Recent E-Risk findings show: 1️⃣ Some harms weren’t recognised earlier 2️⃣ Recalling/sharing later isn’t easy 3️⃣ People reinterpret experiences over time Each reporter adds a unique and important perspective 💡 @SGDPCentreKCL

How does screen time affect loneliness? ☹️ Working with E‑Risk, Dr Timothy Matthews examined young people’s online habits 🛜 📺 TV, gaming & browsing linked to greater loneliness 📱 Social media platforms showed no such link @SGDPCentreKCL @KingsIoPPN @kcsamh @The_MRC
