I've been following reporting on this story from other sources, and am not convinced yet that the data is really useful. The way it's reported by popular media is all about an attention-grabbing headline. People love bad news about good habits
For those interested, here is more detail:https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-022-02468-0
Just for a start, "vegetarian" and "vegan" are pretty unscientific terms. It doesn't necessarily tell us how long they have been following a particular diet, how strictly they follow it, whether they have adequate Vitamin-D levels, what pre-existing and lifestyle conditions they have...so many unanswered questions.
You also can't always tell, from the information given, if the subjects exercise, how much,in what way and for how long they have been doing it. Or how honestly and accurately they fill out self-reporting questionnaires.
Personally, I haven't eaten meat in 40+ years, for ethical reasons, and wouldn't do it even if i were convinced that I was at a higher risk for fractures. So I don't care - even if it was proven to be harmful, I wouldn't change my WOE.
So far, I'm a fit active septuagenarian with no broken bones as yet - I'm sticking with what works for me.
P.S. So many other factors in why hip fractures occur should be considered -particularly for prevention. Side effects of medication is a very common one. Women taking all the meds resulting from preventable lifestyle diseases are be more likely to have dangerous falls. There is quite a bit of literature on this. Here's a sample:
