Abstract:
Objective To investigate the vitamin D level among children aged 0-12 years old and its correlation with hemoglo‐bin (HGB) level .Methods 3 254 children aged 0-12 years old in the child healthcare department of our hospital during 2013 were selected .The basic development indicators were collected and the fasting blood was extracted for detecting the related clinical indi‐cators of 25‐hydroxyl vitamin D level ,HGB ,etc .The situation of vitamin D overall distribution and distribution among different age stages were performed the preliminary statistical analysis ;the correlation between vitamin D level among different age stages with HGB was investigated .Results The vitamin D level among 78 .9% of children in Chenzhou city was in the normal level .The pe‐ripheral blood vitamin D level showed the significantly decreasing trend with the age increase (r= -0 .510 ,P<0 .05) .Our study found that the HGB levels during 3 age stages of 0- <2 ,4- <6 and 7- <10 years old in the normal vitamin D level group were obviously higher than that in the low vitamin D level group .The vitamin D level in children was positively correlated with HGB(lev‐el P<0 .05) .The further research found that the vitamin D level in the age stages of 0- <2 ,4- <6 years old was positively corre‐lated with the HGB level(P<0 .05) ,while no correlation between them was found in the age stage of 7- <10 years old .Conclusion The vitamin D nutritional status in children of Chenzhou city is good in general now .The vitamin D level in children appears a ob‐viously downward trend with the age increase ,which conformed to the children′s growth and development characteristics ;in differ‐ent age stages ,the positive correlation exists between children′s vitamin D and HGB levels ,the vitamin D deficiency may affect chil‐dren′s hemoglobin generation ,thus could lead to anemia occurrence in children .
