Growth in height was measured with the same birth cohorts, not by comparing mean height of ascending ages in the same year. Starting from a lower economic base and mean height in the 1960s, high school males aged 17 in South Korea became 3 cm taller in mean height than their Japanese peers in the mid-2000s versus 2 - 3 cm shorter in the 1960s through 1970s. Children in Japan ceased to grow taller by the end of the 1980s, not because they quit taking more animal-sourced foods, meat and milk, but because they had drastically steered away from fruit and vegetables in their diets since the end of the 1970s. Having largely converged economically with Japan, South Korean children ceased to grow any taller in the mid-2000s. More importantly, it was discovered in this study that successive cohorts in South Korea started to fall gradually but steadily in height growth velocity from 1<sup><span style="font-family:Verdana;font-size:12px;">st</span></sup><span style="font-family:Verdana;font-size:12px;"> graders in middle school, aged 12 years to 3</span><sup><span style="font-family:Verdana;font-size:12px;">rd</span></sup><span style="font-family:Verdana;font-size:12px;"> graders in high school, </span><span style="font-family:Verdana;">and </span><span style="font-family:Verdana;">aged 17 years, to be once again 3 cm below their Japanese peers in the early-2010s.

Education has always been a deeply emotional topic for Chinese parents. A recent proposal calling for postponing boys' school starting age by one year has led to even more heated discussions on the topic.
