Correlation analysis of marginal vitamin A deficiency and growing pains in children from Chongqing and surrounding areas

Abstract:

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，including 53 boys and 58 girls with an aver－age age of 5.8 years old. And 176 checkup children at the same period were selected as control group，including 100 boys 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 was compared between the two groups. Results：There were 70 children of marginal vitamin A deficiency in the observation group，and 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， χ2=5.104，P<0.05）. Conclusion：Marginal vitamin A deficiency may be associated with growing pains in children from Chongqing and surrounding areas.
