Height, education and later-life cognition in Latin America and the Caribbean.

Building on previous evidence from the U.S., this study investigates the relationship between anthropometric markers (height and knee height), early-life conditions, education, and cognitive function in later life among urban elderly from Latin America and the Caribbean. I document a positive association between height and later-life cognitive function, which is larger for women than for men. This sex difference increases when I address potential feedback effects from mid- and later-life circumstances on stature by using knee height as an instrument for height. Specifically, while the estimates for women remain largely unchanged, I only find a diminished and statistically insignificant association between instrumented height and later-life cognition for men. This finding suggests that at least part of the association between height and later-life cognition among men may stem from common third factors that are correlated with both height and later-life cognition, such as adverse occupational exposures or health events during mid- and later life. Extended models that also include education further diminish the association between height and later-life cognition. Education displays strong positive gradients with the employed measures of childhood circumstances - including height - which points to education as a potential pathway linking early-life conditions and later-life cognitive function.
