New paper out in PNAS! We show that becoming a grandparent substantially reduces employment and earnings, especially for women. At the same time, grandparents go more to the doctor for respiratory infections, but less for mental health conditions. www.pnas.org/doi/10.1073/...

Article alert!🚨 1/11 Parents matter - and we can quantify part of that influence genetically. Our new JCPP paper on multivariate indirect maternal genetic effects across internalizing and externalizing symptoms. doi.org/10.1111/jcpp... #jcpp @uio.no @unioslo-svfak.bsky.social @unioslo-uv.bsky.social

I drafted a letter to the editor, please help me out by DMing, commenting, emailing feedback if you are an expert on colliderbias, id obviosuly ad you as a author, Ideally we submit within 24-48 hrs, draft: zenodo.org/records/1800... (click download if the pdf doesnt preview on zenodo)

This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!

1/4 Thrilled to be sharing new work published today in Nature describing the third wave of results from the PGC Cross-Disorder Group. This reflects a massive group effort to examine shared and unique genetic signal across >1 million cases for 14 psychiatric disorders. www.nature.com/articles/s41...

Who wants to join us in Oslo to study how health influences educational underperformance? We are hiring PhDs postdocs candidates for our funded project. We will follow children from birth to emerging adulthood, using behavioural genetic methods and large datasets 945000.webcruiter.no/Main/Recruit...

Key insights (2/2) • 10 years later, employed grandmothers are 12% less likely to work full-time, compared to a 2% reduction for grandfathers. Women also see larger income drops. • The gendered patterns in infections + employment suggest women still are more involved in informal childcare provision.

Key insights (1/2) • Respiratory infections jump in the first years of grandparenthood: +56% for women, +31% for men • Grandparents are slightly less likely to see a doctor for mental disorders (−4.5%) & cardiovascular issues (−3.3%) • Grandmothers have fewer musculoskeletal-related visits (−3.8%)

New preprint📈📉 What happens to health and work when people become grandparents? Using Norwegian register data on all individuals born 1950-1960, we use event-study models comparing grandparents to not-yet grandparents to track changes in health and labour supply. 🔗 www.ssrn.com/abstract=571...

Since search is dead, how soon do you think Google Scholar is headed for the Google Graveyard? I'm betting it's soon, and academia is NOT prepared

Here is a free link to the paper if you don't have access:: onlinelibrary.wiley.com/share/author... I also wrote a more detailed thread when I posted the preprint last year. Check it out here if you are interested: bsky.app/profile/hfsu...

Accompanying the paper is an interactive web page with figures and tables showing the prevalence of psychological codes in the ICPC-2 by age, sex, and parental income quartile. Check it out here: hfsu.shinyapps.io/prevalence_b...

Our new paper is out today! 🎉 In it, we use administrative register data to document how psychiatric disorders are strongly linked to parental income, from childhood far into adulthood. Furthermore, we attempt to separate causation and selection using kinship-based models. doi.org/10.1111/jcpp...

Our new study is just out in Psychological Science! We study cognitive ability at age 18 and mental health 20 years later in 270k Norwegian men. We include different mental disorders, compare education by ability, and run sibling-fixed effects. Check it out here: doi.org/10.1177/0956...

3/7 🎓 Educational attainment also independently predicted better mental health. But the highest risk was for men who were low in both cognition and education. This group faced the highest probability of adult psychiatric diagnoses.

🧵1/7 New study: How do adolescent cognitive ability and education predict adult mental disorders? 🧠📚➜🧑‍⚕️ Using Norwegian register data (N = 272,351 men) of GP diagnoses and military assessed cognitive abilities. 👇

Last week, our new paper on indirect assortative mating was published.🍾 Let’s take a closer look at what this means, why it matters, and what we found (🧵/32): www.nature.com/articles/s41...

1/13 New preprint out! We developed methods to test a key assumption in family-based genetic studies: that siblings don’t genetically influence each other’s traits. Spoiler: mostly they don’t, but there’s a twist with ADHD ratings at age 3 👶 osf.io/preprints/ps...

I will write a detailed thread next week. If something is confusing until then, I highly recommend the supplementary notes, where I go through the logic more slowly and in greater depth.

Results imply that partners are strongly assorting (r=.68) on education-associated trait(s) with large shared-environmental effects (i.e. Social Homogamy). Accounting for this in intergenerational models reveals previously hidden or underestimated environmental effects.

Our paper on indirect assortative mating is now out in @natcomms.nature.com! In it, we provide refined definitions of terms used to explain partner similarity, develop statistical models, and find evidence of surprisingly high social homogamy for education. Link: doi.org/10.1038/s414...

Very grateful that I got to present at the ESSGN past Friday. In the study I presented, we looked at intergenerational transmission of education in a sample of the Norwegian population register. We used a Children-of-Twins model to look at GPA at age 16 and educational attainment in the parents.

New preprint! We find no evidence that parental mental health influences children's academic achievement when comparing families in the Norwegian MoBa study. osf.io/preprints/ps... Quick thread 👇

🚨 Big question, big paper! Why does educational inequality run in families? The parent-child education link (r = .31) is often seen as purely environmental. From 569k kids, we decomposed it: 🧬 68% genetic 🏡 12% parental environment 👴 20% extended-family environment 👉 doi.org/10.31234/osf... 🧵

Vi har et skrikende behov for kunnskap for å møte vår tids utfordringer, med fallende skoleprestasjoner og økt fravær. Derfor er det avgjørende med et nasjonalt individdataregister fra skoler og barnehager, mener Camilla Stoltenberg, @martinflato.bsky.social, @torvik.bsky.social og Karin Monstad.

Fallende skoleprestasjoner og økt fravær avdekker et skrikende behov for kunnskap for å møte vår tids utfordringer. Til det trenger vi registre fra skoler og barnehager. www.altinget.no/lovebakken/a...

I dag får bare 0,6 % av barn utsatt skolestart i Norge. Det er alt for få, og det kan ha alvorlige konsekvenser for umodne barn www.nrk.no/ytring/fleks...

Hvorfor er det tilsynelatende umulig for folk å forstå at dersom statens råd skal ha legitimitet så må de være basert på forskning og fakta og ikke bare være noe som mest mulig er på linje med følelsene til ressurssterke bekymrede foreldre? Og at man kan gjøre ting uten at staten sier det?

You've heard of DNA, but what about GNA? Very excited about this preprint with @jgthorp.bsky.social and others that introduces Genomic Network Analysis (GNA), an open-source multivariate tool for performing network analysis using GWAS summary statistics as input. 1/2 www.medrxiv.org/content/10.1...

(1/10) Check out our new paper in Nature Communications! “Non-random mating patterns within and across education and mental and somatic health”. In the paper, we study partner similarities before they (were likely to have) met. www.nature.com/articles/s41467-024-54966-9

I am happy to report that I have commenced my research stay at the Norwegian Institute for Public Health in Oslo! I re-united with my supervisor dr. Elsje van Bergen on Tuesday. Together with @torvik.bsky.social and @hfsunde.bsky.social we will study intergenerational transmission of education.

How do parents matter for their children's heath? In our new paper, we find that parents’ education and income strongly predict early adult mortality. However, once we account for children's own school performance, social background is no longer important. www.nature.com/articles/s41...

🚨 New study alert! 🚨 We find that socioeconomic background—parents' income and education—strongly predicts early adult mortality.

New preprint 📈📉 🧠👶🏻 We explored the link between parenthood and mental health in over 2M Norwegians using primary health care records. We found that parents generally experienced fewer mental disorders, even after accounting for factors like education and marital status. 🔗 doi.org/10.1101/2024...

Hello all Oslo-people: Next Wednesday (20th of Nov), my colleagues and I will be at Kulturhuset and present research findings about social differences and mental health. The event is open to all (but will be in Norwegian): www.fhi.no/om/kurs-og-k...

Psykisk helse hos barn varierer sterkt etter foreldrenes inntekt og utdanning. Hvorfor er det sånn? I fire år har vi forsket på sosial ulikhet, psykisk helse og genetikk. Kom på Kulturhuset onsdag 20. november kl. 9, så får du høre hva vi har funnet ut! www.fhi.no/om/kurs-og-k...

We have a new preprint!📰Here, we describe the association between parental income and psychiatric disorders from childhood and into adulthood, and use children of twins and siblings to differentiate social selection from social causation (1/n)🧵 Link: doi.org/10.1101/2024...

This paper has been years in the making, and I'm happy to finally share it. Thanks to all co-authors who helped along the way (e.g., @torvik.bsky.social). For more details, see the preprint: doi.org/10.1101/2024...
