Little is known about Se intakes and status in very young New Zealand children. However, Se intakes below recommendations and lower Se status compared with international studies have been reported in New Zealand (particularly South Island) adults. The Baby-Led Introduction to SolidS (BLISS) randomised controlled trial compared a modified version of baby-led weaning (infants feed themselves rather than being spoon-fed), with traditional spoon-feeding (Control). Weighed 3-d diet records were collected and plasma Se concentration measured using inductively coupled plasma mass spectrometry (ICP-MS). In total, 101 (BLISS 50, Control 51) 12-month-old toddlers provided complete data. The OR of Se intakes below the estimated average requirement (EAR) was no different between BLISS and Control (OR: 0·89; 95 % CI 0·39, 2·03), and there was no difference in mean plasma Se concentration between groups (0·04 μmol/l; 95 % CI -0·03, 0·11). In an adjusted model, consuming breast milk was associated with lower plasma Se concentrations (-0·12 μmol/l; 95 % CI -0·19, -0·04). Of the food groups other than infant milk (breast milk or infant formula), 'breads and cereals' contributed the most to Se intakes (12 % of intake). In conclusion, Se intakes and plasma Se concentrations of 12-month-old New Zealand toddlers were no different between those who had followed a baby-led approach to complementary feeding and those who followed traditional spoon-feeding. However, more than half of toddlers had Se intakes below the EAR.
对于新西兰幼儿的硒摄入量和硒状况，人们了解甚少。然而，有报告称，新西兰（尤其是南岛）成年人的硒摄入量低于建议值，且与国际研究相比，其硒状况较低。“婴儿主导的固体食物引入法”（BLISS）随机对照试验比较了改良版的婴儿主导式断奶法（婴儿自主进食而非用勺子喂食）与传统勺子喂食法（对照组）。收集了为期3天的称重饮食记录，并使用电感耦合等离子体质谱法（ICP-MS）测量血浆硒浓度。共有101名（BLISS组50名，对照组51名）12个月大的幼儿提供了完整数据。BLISS组和对照组低于估计平均需求量（EAR）的硒摄入量的比值比无差异（比值比：0·89；95%置信区间0·39，2·03），两组间血浆硒浓度均值也无差异（0·04 μmol/l；95%置信区间 -0·03，0·11）。在一个校正模型中，食用母乳与较低的血浆硒浓度相关（-0·12 μmol/l；95%置信区间 -0·19，-0·04）。在除婴儿奶（母乳或婴儿配方奶粉）之外的食物类别中，“面包和谷物”对硒摄入量的贡献最大（摄入量的12%）。总之，采用婴儿主导式辅食添加法的12个月大新西兰幼儿与采用传统勺子喂食法的幼儿在硒摄入量和血浆硒浓度方面并无差异。然而，超过半数的幼儿硒摄入量低于EAR。
