So let’s start with some background. What is an ecological study?
It may sound like it’s about the environment, but that’s not really true.
In epidemiology, an ecological study is one where all data about groups not individuals.

What does that mean?
For example, we might know how much chocolate per capita is eaten in countries around the world and we might also know how many Nobel Prize winners each country has had.

It’s time for some #cartoonepi & #epiquiz fun!
Today, let’s talk about Difference-in-Difference analyses and how to use them to estimate the impact of policy changes!
Our example paper is from our May issue by @DrRitaHamad & colleagues.

First, some background for those of you not familiar with the WIC program.
WIC stands for “Special Supplemental Nutrition Program for Women, Infants, and Children”, and provides vouchers for specific food combos (‘packets’) for low-income pregnant women & kids <5yo in the US.

Happy Tuesday, #epitwitter! There’s been a lot of discussion #onhere about #causalinference lately, but that’s not all that epi is about.
For this week’s #epichat with @epiellie, let’s talk about descriptive epi!

Next question — this one’s for discussion so share your thoughts!
What differentiates descriptive epi from causal inference epi?
