Looking at the paper, the rate in their younger cohort went from about 1.6 or 1.7 per 100,000 pre pandemic (read from a plot, I didn't check to see if they give a specific number in the text) to about 2.1 per 100,000 during the early phase of the pandemic. That's small enough to potentially be explained by all sorts of factors. And then of course the causes could be split among several factors. Doesn't really justify speculation about what factors might increase personal risk.
