Analysis On The Risk Factors Of Vitamin D Deficiency In Children Aged 6~9 Years Old

Objective:To analyze the risk factors of vitamin D deficiency in children aged6~9 years old.and pay attention to the situation of vitamin D deficiency in children,so as to provide some clinical reference value for the diagnosis and treatment of related clinical diseases.Methods:From July 2018 to July 2019,the data of serum 25-(OH)D for children aged 6 to 9 years who came from the outpatient clinic of child healthcare department in Ningxia Hui Autonomous Region People's Hospital were collected.The data of204 children aged 6 to 9 years were collected by self-designed questionnaire and then analyzed for correlative factors.The children were divided into two groups according to their serum 25-(OH)D levels: normal vitamin D group(n = 77)and vitamin D deficiency group(n = 127).Univariate analysis and binary logistic regression were used to analyze the relationship between various factors and vitamin D deficiency.Resultsz:Statistically significant differences were found between normal and vitamin D deficient children in season of examination,cod liver oil supplementation before the age of 2,average daily outdoor activity time in the past one month,average sun exposure area in the past one month,sunscreen usage,milk drinking,egg eating,fungus eating,and oral cod liver oil intake in the past two months(P<0.05).Winter(OR=4.473,95%CI:1.240~16.132,P=0.022),irregular cod liver oil supplementation before 2 years old(OR=8.261,95%CI:3.058~22.311,P<0.001),never eating eggs(OR=7.593,95%CI:1.732~33.294,P=0.007),occasionally eating eggs(OR=3.691,P<0.001);never eating seafood(OR=7.303,95%CI:1.494~35.696,P=0.014);occasionally eating seafood(OR=10.625,95%CI:2.373~47.575,P=0.002)was independent risk factors for vitamin D deficiency.The risk factors of vitamin D deficiency were winter,irregular supplementation of cod liver oil and before 2 years old,lack of frequent eggs eating and milk drinking.Conclusion:The risk factors of vitamin D deficiency were winter,irregular supplementation of cod liver oil and before 2 years old,lack of frequent eggs eating and milk drinking.
