Analysis of the current situation of defect of vertebral column among primary， middle， and high school students in Minhang District， Shanghai

Abstract

ObjectiveTo investigate the general situation of defect of vertebral column among primary and middle school students in Minhang District of Shanghai and analyze the related factors， to provide a scientific basis for prevention and treatment.MethodsFrom September to October 2022， a total of 5 715 students were selected from two primary schools， two middle schools， and two high schools in Minhang District for physical examinations and screening for defect of vertebral column.ResultsTotally 219 students had defect of vertebral column， accounting for 3.83% of the sampled population. Anteroposterior spinal abnormalities were found in 4 individuals， accounting for 0.07%， and 218 students had scoliosis， accounting for 3.81%. The detection rate of defect of vertebral column was higher in girls （6.27%） than that in boys （1.51%）， and higher in high school students （10.74%） than in primary school students （1.31%） and middle school students （10.97%）. Students who are mildly underweight （5.95%） and who are moderately to severely underweight （7.46%） had a higher detection rate of defect of vertebral column than those with normal weight （4.54%）， overweight （2.83%）， and obesity （1.60%）. The detection rate among students with poor vision （4.32%） was significantly higher than those with normal vision （2.24%）， with all differences statistically significant （all P<0.05）.ConclusionThe positive rate of defect of vertebral column in primary and middle school students in Minhang District， Shanghai is nearly 4%， with most cases being scoliosis. Factors such as being female， increasing age， being underweight， and poor vision are associated with a higher probability of detecting defect of vertebral column.
