Abstract
Background and objectives: The usual recommended intake of vitamin D for healthy infants is 400 international unit (IU) daily. However, a high dose of vitamin D at 2000-3000 IU daily is needed for those with vitamin D deficiency (VDD). This study aimed to assess the natural history of a group of healthy infants with VDD and the associated factors for persistent VDD.
Methods and study design: Healthy infants detected to have VDD (25OHD <25 nmol/L) in a population study were followed, and their demographics and clinical data were collected.
Results: One hundred and thirty-one subjects (boys = 66%) were included. Their first serum 25OHD was taken at a median age of 87.5 days. None were treated with high-dose vitamin D supplements, but some have been given vitamin D at 400 IU daily. They were assessed again at the median age of 252.5 days when 15 remained to have VDD and 26 were in the insufficient range (25 - 49.9nmol/L). All persistent VDD children were on exclusive breastfeeding. Exclusive breastfeeding and no vitamin D supplementation were significant risk factors for persistent vitamin D insufficiency (<50nmol/L).
Conclusions: Persistent VDD is common among infants exclusively breastfeeding and those who did not receive vitamin D supplementation.
背景和目的：健康婴儿通常建议每天摄入 400 国际单位（IU）的维生素 D。然而，维生素 D 缺乏症（VDD）患者需要每天摄入 2000-3000 国际单位的高剂量维生素 D。本研究旨在评估一组患有维生素 D 缺乏症的健康婴儿的自然病史以及导致维生素 D 缺乏症持续存在的相关因素：方法与研究设计：检测出患有维生素 D 缺乏症的健康婴儿（25OHD 结果：131 名受试者（男孩、女孩、男孩和女孩共纳入 131 名受试者（男孩 = 66%）。他们的首次血清 25OHD 检测的中位年龄为 87.5 天。他们都没有服用大剂量维生素 D 补充剂，但有些人每天服用 400 IU 的维生素 D。他们在 252.5 天的中位年龄时再次接受评估，当时有 15 名儿童仍有 VDD，26 名儿童的血清维生素 D 含量处于不足范围（25 - 49.9nmol/L）。所有持续存在 VDD 的儿童都在接受纯母乳喂养。纯母乳喂养和未补充维生素 D 是导致维生素 D 持续不足的重要风险因素：在纯母乳喂养和未补充维生素 D 的婴儿中，持续维生素 D 不足的情况很常见。
