目的 分析0～3岁婴幼儿血清25羟维生素D缺乏的影响因素.方法 选取2016年8月至2022 年12 月苏州市立医院儿童保健门诊的 862 例 0～3 岁婴幼儿,根据血清 25 羟维生素D水平分为观察组(血清 25羟维生素D<10～30 ng/ml)和对照组(血清 25 羟维生素D>30～100 ng/ml).采用logistic回归分析 0～3 岁婴幼儿血清 25 羟维生素D缺乏的影响因素.结果 两组年龄、喂养方式、户外活动时间、婴幼儿维生素D补充情况、母亲孕期维生素D补充情况比较,差异有统计学意义(P<0.05).多因素分析发现,年龄<1岁、纯母乳喂养、户外活动时间<1 h/d、婴幼儿未额外补充维生素D、母亲孕期未补充维生素D是 0～3 岁婴幼儿血清25 羟维生素D缺乏的危险因素(P<0.05).结论 年龄<1岁、纯母乳喂养、户外活动时间<1 h/d、婴幼儿未额外补充维生素D、母亲孕期未补充维生素D是 0～3 岁婴幼儿血清 25 羟维生素D缺乏的危险因素.
Abstract
Objective To analyze the influencing factors of serum 25-hydroxyvitamin D deficiency in infants aged 0-3 years.Methods A total of 862 infants aged 0 to 3 years old who were admitted to the Department of Child Health of Suzhou Municipal Hospital from August 2016 to December 2022 were selected and divided into the observation group(serum 25 hydroxyvitamin D<10-30 ng/ml)and the control group(serum 25 hydroxyvitamin D in>30-100 ng/ml)according to their serum 25 hydroxyvitamin D levels.The logistic regression was used to analyze the influencing factors of serum 25-hydroxyvitamin D deficiency in infants aged 0-3 years.Results There were statistically significant differences in age,feeding style,outdoor activity time,vitamin D supplementation of infants and mothers during pregnancy between the two groups(P<0.05).Multivariate analysis showed that age<1 year,exclusive breastfeeding,outdoor activity time<1 h/d,infants without additional vitamin D supplementation,and mothers without vitamin D supplementation during pregnancy were the risk factors for serum 25-hydroxyvitamin D deficiency in infants aged 0-3 years(P<0.05).Conclusion Age<1 year,exclusive breastfeeding,outdoor activity time<1 h/d,infants without additional vitamin D supplementation,and mothers without vitamin D supplementation during pregnancy are risk factors for serum 25-hydroxyvitamin D deficiency in infants aged 0-3 years.
