Over 5 million primary and high school students in China currently suffer from spinal deformities, with the numbers increasing by about 300,000 every year, Global Times reported.

According to a report by China Central Television (CCTV), scoliosis has become the third major disease endangering the health of Chinese children and adolescents following obesity and myopia.

It appears in childhood or adolescence when children and adolescents grow and develop the fastest.

Females at the peak of their growth are more likely to suffer from the disease, with an incidence rate up to 1.5 times as often as males.

According to the report, a 13-year-old girl from Hengshui in North China's Hebei Province was diagnosed with severe scoliosis, which a doctor thought was caused by long-term poor sitting posture.

If her condition is not fixed, it could result in uneven shoulders, legs of different lengths, body deformities and other serious consequences, the report said.

On China's Twitter-like Sina Weibo, many netizens attributed the situation to students' heavy schoolbags, and inappropriate sizes and heights of desks for children in different physical developmental stages.

According to Liu Haiying, head of the department of spine surgery at Peking University People's Hospital, scoliosis is a deformity of the spine that causes it to deviate from the normal midline, which is combined with a rotation of the spine.
