“U.S. children,” write Mr. Komlos and Mr. Lauderdale, “consume more meals prepared outside the home, more fast food rich in fat, high in energy density and low in essential micronutrients, than do European children.” Our reliance on fast food, in turn, may reflect lack of family time because we work too much: U.S. G.D.P. per capita is high partly because employed Americans work many more hours than their European counterparts.
A broader explanation would be that contemporary America is a society that, in a variety of ways, doesn’t take very good care of its children. Recently, Unicef issued a report comparing a number of measures of child well-being in 21 rich countries, including health and safety, family and peer relationships and such things as whether children eat fruit and are physically active. The report put the Netherlands at the top; sure enough, the Dutch are now the world’s tallest people, almost 3 inches taller, on average, than non-Hispanic American whites. The U.S. ended up in 20th place, below Poland, Portugal and Hungary, but ahead of Britain.
Whatever the full explanation for America’s stature deficit, our relative shortness, like our low life expectancy, suggests that something is amiss with our way of life. A critical European might say that America is a land of harried parents and neglected children, of expensive health care that misses those who need it most, a society that for all its wealth somehow manages to be nasty, brutish — and short."
