Pure speculation, but maybe the trauma of the false-positive candidate gene papers made us more likely to publish null GxE results using polygenic scores. But I might just be imagining it 😊

Btw @astabreinholt.bsky.social and I are doing a meta-analysis on GxSES studies on edu outcomes assessing publication bias and so on - but it’s still in progress 😊

Immigrants typically arrive in good health but experience fast health declines. Is the same true for Asylum Seekers though?

Check out my latest publication on PDR: doi.org/10.1111/padr...

Short answer: yes for (self-reported) physical health, but the opposite is true for mental health!

In many journals associate editors play an important role in the review process but their names don’t appear in communications with authors. At Europ Soc Rev, when we reject a paper the letter is signed by both EiC and AE. In others only the EiC signs. Having the AE in the letter adds transparency

Contributing to research on health inequalities and sociogenomics, I find: 

1) PGI BMI is more predictive of high levels of BMI among individuals from *low-SES families*
2) This pattern is weakened over the life course but *persists* among individuals with high BMI levels

This work tests the expectation from the compensatory advantage and diathesis-stress theories by using the Add Health data. Specifically, it assesses whether the association between a PGI BMI and BMI at different life stages (ages 16, 22, 28, and 37) is shaped by family socioeconomic status.

I study the genotype-family SES interaction on obesity and overweight across the life-course.   

I ask whether the genetic propensity for high BMI matters more in explaining overweight and obesity among individuals from low or high-SES families? And if so, does this interaction vary by age?

It shows a mechanism underlying the intergenerational transmission of health inequality: high-SES families buffer genetic propensity for obesity & overweight, while low-SES environments trigger it 🌍🧬⚖️

Must-read for anyone considering Mendelian Imputation to increase their genetic sample.
Is the potential benefit really outweighing the risks?

When conception rates fluctuate, preterm birth proportions shift predictably but with different magnitudes depending on baseline risk. 1/4

New paper with @fabriberna.bsky.social - part of my PhD thesis!

Why are the negative educational consequences of parental separation stronger among high-SES children?

→ When high-SES parents separate, they lose their ability to compensate for their child’s low genetic propensity for education 🧬👪
