Selenium status was assessed in 28 infants receiving either human milk (n = 8) or a proprietary formula (n = 20) as their sole nutritional source from birth to 3 months. Infants' selenium intakes were determined from dietary records, "test weighings," and direct analysis of human milk and formula. Fore milk samples (n = 72) collected from group I mothers had a mean selenium concentration (ng/ml) of 16.3 +/- 4.9, whereas the selenium content of proprietary formula was 8.6 +/- 0.9. The selenium concentration of hind milk was significantly greater (p less than 0.05) than that of fore milk. At 3-months selenium intakes as well as serum selenium concentrations for human milk fed infants were significantly greater than those for formula fed infants. A significant positive correlation (r = 0.42; p less than 0.05) was found between infants' selenium intakes and their serum selenium concentrations. The results indicate that feeding practice directly affects selenium status during infancy.
对28名从出生到3个月以母乳（n = 8）或一种专利配方奶粉（n = 20）作为唯一营养来源的婴儿的硒状况进行了评估。婴儿的硒摄入量通过饮食记录、“试重法”以及对母乳和配方奶粉的直接分析来确定。从第一组母亲收集的前奶样本（n = 72）的平均硒浓度（ng/ml）为16.3±4.9，而专利配方奶粉的硒含量为8.6±0.9。后奶的硒浓度显著高于前奶（p＜0.05）。3个月时，母乳喂养婴儿的硒摄入量以及血清硒浓度显著高于配方奶粉喂养的婴儿。婴儿的硒摄入量与其血清硒浓度之间存在显著正相关（r = 0.42；p＜0.05）。结果表明，喂养方式直接影响婴儿期的硒状况。
