Overall health declining as obesity rises, leading to calls for more exercise
Health and sports specialists are calling for more exercise and better nutrition amongChinese students after a controversial comparison of the height of teenagers in China withthose in neighboring countries.
The claim that Chinese teens' average height falls short of their Japanese and SouthKorean counterparts surfaced at the National People's Congress in March, promptingpublic concern that students' fitness levels have plunged.
Specialists at a recent youth sports event shrugged off the comparisons, though theyhighlighted the importance of adequate exercise and diet as non-genetic factors behindoverall health.
One fitness expert rejected the notion that Chinese youths are shorter than Japanese orSouth Koreans.
"The conclusion is inaccurate without official statistical analysis, and the comparison onheight doesn't necessarily reflect people's fitness level in different countries," Tian Ye,director of the China Institute of Sport Science, said at the launch of preparations for the2014 Sunshine Youth Sports event.
In March, Beijing educator and NPC deputy Wu Zhengxian claimed that the averageChinese teen is shorter than their Japanese or Korean peers.
Wu was not available to clarify her sources, but some figures suggest different results.
An average 17-year-old Chinese male in 2010 stood 171.4 centimeters in height, while theaverage female was 159.3 cm, according to figures from the National Fitness Surveyreleased by the State Administration of Sport of China in 2011.
That's taller that Japanese youth of either sex.
According to e-Stat, the portal site of official statistics for Japan, the corresponding figuresin Japan were 170.7 cm and 158 cm in 2011. A Seoul National University study showedSouth Korean males at 173.6 cm and females at 160.9 cm on average in the same period.
Rather than debate the merits of different heights, it would be more meaningful to push forincreased physical education activities for students in China, said Li Guoping, director ofthe National Institute of Sports Medicine.
"Human body height is mainly decided by genetic factors and will be slightly affected byhabitual exercise. It's not convincing to compare fitness level with the differences inheight," Li said.
"However, the health status of Chinese teenagers is indeed worsening. We should work onproviding children with more mandatory exercise on campus, which I believe wouldeventually boost the average height of Chinese."
Because of the overemphasis on academic excellence in China's exam-oriented educationsystem, facilities and hours for physical education lag behind academic courses. This hasresulted in a decline in overall student fitness levels, PE boosters say.
In the Chinese capital, of the 1.3 million primary and secondary school students sampled inthe 2013 Beijing student physical fitness survey, 21.46 percent were obese while 62.96percent suffered from myopia - less-than-perfect eyesight.
Some chronic diseases have also begun to hamper teenagers' development. Of 401 juniorand senior high school students in one sample, 45.1 percent were diagnosed with fattylivers and 30.7 percent were found to be suffering from hypertension.
