Investigation On Infants And Toddlers Supplementing Cod Liver Oil In Child Health Department

Background:Cod liver oil contains vitamin A(VA)and vitamin D(VD),which play a major role in children's growth and development.Clinically,vitamin D in cod liver oil is mainly used to prevent rickets,and vitamin A in cod liver oil can prevent night blindness and xerophthalmia.A large number of domestic epidemiology shows that the infants and toddlers still have a high vitamin A and D deficiency rate.Supplementing cod liver oil can prevent these diseases,but there is less investigation and research on cod liver oil supplementation.Objective:To investigate the supplementation of cod liver oil in infants and toddlers undergoing physical examination in the Children's Health Department of Children's Hospital of Chongqing Medical University.Methods:A total of 392 healthy children younger than 3 years of age were enrolled in the Child Health Unit of Children's Hospital of Chongqing Medical University in March 2018 to participate in this study.Questionnaire surveys were used to obtain general information about children andsupplementation of cod liver oil.Chi-square test was used to analyze the count data.Results:There were 292(74.5%)cod liver oil supplements in 392 infants and toddlers,of which 226(57.7%)had both VA and VD,66(16.8%)had only VD,and There were 100(25.5%)children without cod liver oilsupplements.The supplementation rates of cod liver oil were 78.9%,72.1%,and 56.5% in the less than 12 month old group,the 12-23 month old group,and the 24-35 month old group,respectively.There were Significance statistical differences between the less than 12 month old and24-35 month old groups(P<0.017).There was no statistical difference between the other groups(P>0.017).The rate of cod liver oil supplementation for breastfeeding,artificial feeding and mixed feeding of infants was 86.3%,65.6%,and 77.8%,respectively.There was a significant statistical difference between breast milk and artificial groups(P<0.017).There was no statistical significant difference between the other groups(P>0.017).The cod liver oil supplementation rate(75.4%)was higher in urban infants and toddlers than in rural areas,but there was no statistical difference(P>0.05)Conclusion:The proportion of cod liver oil supplemented by infants and toddlers at the outpatient clinic is relatively high,but there is still room for improvement.The proportion of irregularly supplemented cod liver oil is high,and it is necessary to strengthen the teaching of cod liver oil usageand dosage.The proportion of vitamin cod liver oil in infancy is the highest,and there is a declining trend as the age increases.It is necessary to strengthen the promotion of cod liver oil supplements for toddlers.The rate of cod liver oil supplementation for breastfed children is higher than that of artificial feeding,and it is necessary to strengthen the mission of supplementing cod liver oil to other feeding methods.
