It looks like this is a meta-analysis, and the line "Twenty studies met the selection criteria representing 171,802 participants with 157,778 meat consumers and 13,259 meat abstainers." suggests that this is a post hoc analysis so we can't rule out the most obvious confounding variable: are people who care more about externalities (e.g., as they pertain to meat eating, more likely to be depressed or anxious?

Seems like this has a lot more to do with the type of people who abstain from meat vs those who do--rather than the effects of eating meat.

People who abstain from eating meat due to animal compassion (empathy) might be more susceptible to depression due to their empathetic disposition.

I am curious whether it implies causation or just correlation. I can easily explain it away with correlation. Most likely vegans will be people who are quite attuned to somebody else's (including animal) suffering. And the same empathy my guess would cause a higher level of anxiety. (All of this obviously, my guesses and I don't have any data to prove it)

I'd say the first big thing to highlight is that correlation is not causation - you wouldn't want someone to take this study as proof that eating meat makes you less depressed. I would imagine that vegans (in particular vegans who chose their diet on ethical grounds) are overall more concerned about the state of the world around them - or are at least subjected to more of an echo-chamber effect from their peers - which would contribute to anxiety and depression?
