Oh yea, smoking too. That would also explain what we observed in China. Almost everyone who smokes in China is a man because there is a stigma that the only women who smoke are prostitutes (or at least that was the case when I lived there over a decade ago). Something like 30% of China smokes, but almost all of those are men, making it over 50% of men smoking.

"In 2015, smoking prevalence was 27.7% (52.1% among men and 2.7% among women)" ref: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6546632/
