Meta-analyses of dietary exposures must consider energy adjustment (preprint) 🧵
arxiv.org/abs/2512.07531

In observational studies, adjustment for energy intake changes the nature of the effect being estimated – from addition (increasing or decreasing intake of that food while...

To join the doctoral school (not the dpt), we had a protocol defense, first evaluated by an expert committee and then presented (with most of the time saved for Q&A).

SAVE THE DATE: The 2026 IEA European Congress of Epidemiology and 70th @socsocmed.bsky.social Annual Conference will take place in London, UK on 8th-11th September 2026!

Advert for causal inference late breaking abstract session

I'm excited to be charing the #SER2025 Causal Inference Late-breaking Abstract Speed Session at 17:30-18:00 in the Liberty room today!

Gogogogogogo

So fantastic to reconnect with @nataliaortega.bsky.social in Boston of all places!

#SER2025

such a pleasure to share time together ❤️

AAAAAAAAAAAAAAAAAAAAAI🥳

Worldwide and time trends in sodium and potassium intakes in children and adolescents: a systematic review and meta-analysis Background High sodium (Na) and low potassium (K) intakes in childhood have health effects across the life course. The objective was to estimate global, regional and national Na and K intakes in child...

"Globally, children’s Na intake was too high, while K intake was too low. Data were lacking in many countries. Interventions are needed to reduce Na and increase K from childhood, and monitoring should be improved" @drtomfrieden.bsky.social #PopHealthLab

With respect to the research question? I'd say an ideal trial is the one that can provide a valid answer to your research question.

Awesome, Peter!!!!!!!!! Bravo!!!!!!!

It's honestly pretty much dead because y'all are not "native" discord users, but @tfeend.bsky.social we can try revive it!!!! :)

Depicting deterministic variables in DAGs, Peter Tennant

My talk on "depicting determinstic variables within DAGs" is now online. The talk explains how DAGs can be used to help with understanding & estimating causal effects involving derived variables (e.g. BMI) & compositional data (e.g. nutrition data).

Passed my viva with minor corrections today 🥳🥹

So difficult to comprehend that it’s happened!

Update: fully into British cuisine. Yesterday we went to TESCO to hunt what would be the most typical "Meal Deal" (for a vegetarian)! 😂 A 5/10

Really excited to be hosting @nataliaortega.bsky.social in Leeds for the next two weeks!

I anticipate lots of conversations about the challenges of doing causal inference in nutritional data! 😂
