This is a great finding, perhaps the beginning of something publishable in a journal. I am embarrassed because Wikipedia has a large table of country-itemized heights, including a sex ratio column, but, when I glanced over it, I expected it was just a random non-relationship.
But the relationship you found should have lined up with my thinking on the matter. Females tend to choose tall men for the sake of male status. I expect that the progression toward "quality" over the industrial revolution is largely a progression toward MATING quality, with men therefore receiving the bulk of the height advantage. The same pattern may therefore apply to the intelligence trend: males have been getting smarter, and so have females but less so.
Relatedly, I found that male height has a greater relationship to covariates than female height. I attributed this to males having greater extremes for any trait, and greater extremes increase correlations, but, come to think of it, male height may be the central point, and female height may be beside the point.
Deep dive?
Deeper than most, at least.

What program do you use to do these regressions?
R
