Abstract

Little is known about the zinc content of breast milk in developing countries. Zinc content in breast milk was analyzed in 34 mothers of low socio-economic status; 17 were primiparae and 17 multiparae. Women in their 6th to 36th week of lactation provided 3 samples of breast milk at different times within a single day. The mean zinc concentration in breast milk (micrograms/ml) was 1.89 +/- 0.64 with a range from 0.17 to 4.38 micrograms/ ml. Zinc content in the morning, midday and evening samples were 2.1 +/- 0.84, 1.74 +/- 0.53, 1.84 +/- 0.69 respectively. There was significant variation between morning and midday samples (p = 0.038). Maternal age, parity, nutritional status or age of the child did not affect the zinc content of milk in the population studied.

摘要

关于发展中国家母乳中的锌含量，人们了解甚少。对34名社会经济地位较低的母亲的母乳锌含量进行了分析；其中17名是初产妇，17名是经产妇。处于哺乳期第6至36周的女性在一天内的不同时间提供了3份母乳样本。母乳中的平均锌浓度（微克/毫升）为1.89±0.64，范围为0.17至4.38微克/毫升。上午、中午和晚上样本中的锌含量分别为2.1±0.84、1.74±0.53、1.84±0.69。上午和中午的样本之间存在显著差异（p = 0.038）。在所研究的人群中，母亲的年龄、胎次、营养状况或孩子的年龄均未影响母乳中的锌含量。
