The HN title should probably say "nonwesternized" (the term used in the abstract) rather than "non-Western" (although the paper subtitle does use "Western"). Still an ambiguous term, but "non-Western population" would usually be understood to include countries like Japan and China, who this study definitely doesn't mean to include.

I was wondering about that; I was just in China and there were tons of people with acne there.

The title of the paper is "Acne Vulgaris - A Disease of Western Civilization."
