摘　　要：目的分析宜宾市0~3岁儿童血清维生素D水平与其监护人营养知识、态度及行为(knowledge,architecture and practice,KAP)的关系。方法采用方便抽样法,抽取2020年1月至12月于宜宾市中医医院等3所医疗机构进行儿童保健的510例0~3岁儿童为研究对象,并按年龄段分类:0~<1岁363例,1~≤3岁147例。收集喂养情况、生长发育情况、生活方式等资料。检测血清25-羟维生素D(25-hydroxy vitamin D,25-OH-D)水平。问卷调查监护人营养KAP。统计学方法采用t检验、ANOVA方差分析、χ^(2)检验、秩和检验和Pearson相关性分析。结果0~<1岁组儿童血清25-OH-D水平高于1~≤3岁组,维生素D不足和缺乏的发生率低于1~≤3岁组;体型超重/肥胖儿童的血清25-OH-D水平低于体型正常和营养不良儿童,维生素D不足和缺乏的发生率高于体型正常和营养不良组;户外活动时间≥2 h/d儿童血清25-OH-D水平高于户外活动时间<2h/d儿童,维生素D不足和缺乏的发生率低于户外活动时间<2 h/d组;维生素D补充量≥300 IU/d儿童血清25-OH-D水平高于<300 IU/d儿童,维生素D不足和缺乏的发生率低于<300 IU/d儿童,差异均有统计学意义(P值均<0.05)。监护人为父母的营养KAP评分均高于其他监护人[知识:(81.9±10.1)分与(68.8±12.5)分;态度:(88.8±7.9)分与(86.1±8.3)分;行为:(79.7±11.2)分与(72.9±12.8)分,P值均<0.05]。Pearson相关性分析结果显示,监护人营养KAP评分与血清25-OH-D水平均呈正相关(r值分别为0.801、0.647和0.836,P值均<0.05)。监护人营养KAP评分与儿童维生素D不足和缺乏有关联性,其列联系数分别为0.469、0.604和0.425。结论宜宾市0~3岁儿童血清维生素D缺乏发生率高,维生素D营养状况与监护人营养KAP评分呈正相关,提高监护人营养KAP评分有利于更好地采取合理措施防控儿童维生素D缺乏。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,χ^(2)test,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 thatguar
