The Correlation Analysis Of Marginal Vitamin A And Growing Pains In Children From Chongqing And Surrounding Areas

Objective:To investigate the correlation of growing pains and marginal vitamin A deficiency in children from Chongqing and surrounding areas,and provide evidence for the clinical treatment of growing pains.Methods:From December 2015 to September 2017,111 children with growing pains in our hospital were chosen as observation group,including53 boys and 58 girls with an average age of 5.8 years old.And 176 checkup children at the same period were selected as control group,including 100boys and 76 girls with an average age of 4.8 years old.The serum level of vitamin A was measured by High Performance Liquid Chromatography,and compared between the two groups.Results:Referring to international standards:vitamin A content below0.7?mol/L(200?g/L)is vitamin A deficiency,0.7~1.05?mol/L(200~300?g/L is subclinical or marginal vitamin A deficiency,higher than 1.05?mol/L(300?g/L)is normal.In the observation group,70 of 111 children were marginal vitamin A deficiency,and that were 87 in the control group.The rate of marginal vitamin A deficiency was significantly different between the two groups(70/111 vs 87/176,chi-square test,X~2=5.104,P<0.05).Conclusion:Marginal vitamin A deficiency may be associated with Growing pains in children from Chongqing and surrounding areas.
