Abstract 【Abstract】 Objective To analyze the relationship between serum vitamin D level among children aged0-3 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 ofYibin and other 2 medical institutions from January to December 2020 were selected as the research objectby convenient sampling method, and they were classified by age group: 363 children aged 0-<1 years and147 children aged 1-≤3 years. Data on feeding, growth and development, and lifestyle were collected. Thelevel of serum 25-hydroxy vitamin D (25-OH-D) was measured. A questionnaire was used to investigatethe nutritional KAP of guardians. Statistical methods performed by t test, ANOVA analysis of variance, χ2test, rank sum test and Pearson correlation analysis. Result The level of serum 25-OH-D in 0-<1 yeargroup was higher than that in 1-≤3 years group, and the incidence of vitamin D deficiency was lower thanthat in 1-≤3 years group. The level of serum 25-OH-D in overweight/obese children was lower than that innormal-size and malnourished children, and the incidence of vitamin D deficiency was higher than thatin normal-size and malnourished children. The serum 25-OH-D level of children with outdoor activitytime ≥2 h/d was higher than that of children with outdoor activity time <2 h/d, and the incidence of vitaminD deficiency was lower than that of children with outdoor activity time <2 h/d. The serum 25-OH-D level inchildren with vitamin D supplementation ≥300 IU/d was higher than that in children with <300 IU/d, and theincidence 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 thatguardian 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 thecolumn 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 isconducive to better taking reasonable measures to prevent and control vitamin D deficiency in children.
