"First, both height and intelligence may be indicators of underlying health. According to this view, people who are genetically and developmentally healthier simultaneously grow taller and become more intelligent than those who are less healthy, producing the positive correlation between height and intelligence.
This is a plausible theory. In our paper, however, Reyniers and I produce evidence against it. In the analysis of the National Longitudinal Study of Adolescent Health, we control for the respondent’s health, by using four indicators of health and producing a latent variable for health using principal component analysis in order to eliminate random measurement error. The association between height and intelligence does not diminish at all when we control for health. In fact, once we control for other demographic and social variables, health is not significantly correlated with intelligence at all; it actually has a nonsignificantly negative association with intelligence. So, at least in our sample, health is unlikely to be the common cause for both height and intelligence."
Other sources online claim that it is overall-increased meat-consumption, not increased dairy-consumption, that is the cause of the increased height.I don't know, were our hunter-gatherer ancestors not supposed to have eaten plenty of meat? I mean, they basically made a great part of the mega-fauna go instinct from hunting, if I'm correct. Perhaps it's a mix of both.
Effect of cow milk consumption on longitudinal height gain in children:
http://ajcn.nutrition.org/content/80/4/1088.2.full
"In summary, in our prospective study, we observed a height gain in the children who consumed a high amount of cow milk."
"Several previous studies showed an effect of milk on height gain in pubertal children. In 1984 Takahashi (4) reported an acceleration of growth in Japan from the 1950s and suggested the importance of milk consumption. And this increase in height was prominent during puberty. In a cross-sectional study, Jirapinyo et al (5) reported that milk intake and parents' height contributed to adolescent height in females. Bonjour et al (6) found that prepubertal girls who consumed a diet including calcium-enriched foods grew in height in a randomized, double-blind, placebo-controlled study. In our longitudinal study, the mean height gain in the high-consumption group was higher than that in the low-consumption group, and the difference in height gain between the 2 groups was 2.5 cm/3 y.

About hip fracture in Japan and other westernized Asian cities (Hong Kong, Singapore...):
http://www.hindawi.com/journals/jos/2010/757102/
"A major study concluded that in a Japan population aged 35 years or older the crude incidence of hip fracture was 244.8 per 100,000 person years from 2004 to 2006, and the gender-specific incidence was 99.6 per 100,000 person years for men and 368 per 100,000 person years for women [12]. When data was analysed and compared with that from 30 years ago it was also concluded that there is an increasing incidence of hip fracture in Japanese populations. The highest incidence of hip fracture from Asia has been reported from Singapore. A study by Koh et al. revealed that hip fracture rates from 1991 to 1998 (per 100,000) were 152 in men and 402 in women, and this was 1.5 and 5 times higher than corresponding rates in 1960s [13]"

I saw one at a supermarket, I found it quite pathetic. I guess we do live in a dangerous world where your child can be kidnapped on the corner of the street, or run over, but it sounds to me like these parents just can't be bothered with properly educating their progeny. Why not just hold hands?
