Relationship between serum vitamin D levels among children aged 0-3 years and nutritional knowledge,attitude and practice of guardians in Yibin
Objective To analyze the relationship between serum vitamin D level among children aged 0-3 years and their guardians'nutritional knowledge,attitude and practice(KAP)in Yibin.Method A total of 510 children aged 0-3 years who received child health care in the Traditional Chinese Medicine Hospital of Yibin and other 2 medical institutions from January to December 2020 were selected as the research objects by convenient sampling method,and they were classified by age group:363 children aged 0-<1 years and 147 children aged 1-≤3 years.Data on feeding,growth and development,and lifestyle were collected.The level of serum 25-hydroxy vitamin D(25-OH-D)was measured.A questionnaire was used to investigate the nutritional KAP of guardians.Statistical methods performed by t test,ANOVA analysis of variance,x2 test,rank sum test and Pearson correlation analysis.Result The level of serum 25-OH-D in 0-<1 year group was higher than that in 1-≤3 years group,and the incidence of vitamin D deficiency was lower than that in 1-≤3 years group.The level of serum 25-OH-D in overweight/obese children was lower than that in normal-size and malnourished children,and the incidence of vitamin D deficiency was higher than that in normal-size and malnourished children.The serum 25-OH-D level of children with outdoor activity time ≥2 h/d was higher than that of children with outdoor activity time<2 h/d,and the incidence of vitamin D deficiency was lower than that of children with outdoor activity time<2 h/d.The serum 25-OH-D level in children with vitamin D supplementation ≥300 IU/d was higher than that in children with<300 IU/d,and the incidence of vitamin D deficiency was lower than that in children with<300 IU/d,with statistical significance(all P<0.05).The nutritional KAP scores of guardian as parents were higher than those of other guardians[knowledge:(81.9±10.1)points and(68.8±12.5)points;attitude:(88.8±7.9)points and(86.1±8.3)points;practice:(79.7±11.2)points and(72.9±12.8)points,all P<0.05].Pearson correlation analysis showed that guardian nutrition KAP score was positively correlated with serum 25-OH-D(r=0.801,0.647 and 0.836,all P<0.05).Guardian nutrition KAP score was associated with vitamin D deficiency in children,and the column associations were 0.469,0.604 and 0.425,respectively.Conclusion There is a high incidence of vitamin D deficiency in children aged 0-3 years in Yibin,and the nutritional status of vitamin D is positively correlated with the nutritional KAP score of guardians.Improving the nutritional KAP score of guardians is conducive to better taking reasonable measures to prevent and control vitamin D deficiency in children.
