Japanese adults shrinking, more babies born with 2,500 grams

Staff Writer |
While the average height of Japanese adults had grown some 15 centimeters over the past century with improved nutrition and public health conditions, it has started to decline for those born in 1980 or later, research showed.

A research team at the National Center for Child Health and Development in Tokyo analyzed data on some 3.15 million adults in Japan and concluded the declining trend in average height may be attributed to increases in low-birth-weight infants in the country, or those who weighed 2,500 grams or lighter at birth.

The findings by Naho Morisaki and other researchers were published in the Journal of Epidemiology and Community Health.

According to the study, average adult height in Japan peaked for those born in 1978 and 1979 at 171.46 cm for men and 158.52 cm for women, while the figures for those born in 1996 stood at 170.82 cm among men and 158.31 cm among women - 0.64 cm and 0.21 cm shorter than peak levels, respectively.

The researchers found "a strong inverse correlation" between the rate of low-birth-weight infants and adult height. While the decline of the average height started among people born in 1980 or later, the number of low-birth-weight babies sharply increased since around that time.

Health ministry statistics showed the ratio of low-birth-weight babies in Japan stood at 5.1 percent in the latter half of 1970s, but it jumped nearly twofold to 9.7 percent in 2007.

Past research has indicated that the height of people with low birth weights tends to be shorter when they grow into adult.
