Hair growth measurements are a sensitive indicator of nutrition and we have assessed their value in the perinatal period. The proportion of growing roots and their diameter were studied at birth in 114 babies and repeated 3 weeks later in 29 low birthweight babies. Intrauterine malnutrition resulted in thinner roots but the changes after birth were not related to nutrition and these measurements will not be useful in feeding studies in this period. At birth, gestational age and sex affected the hair root, and it may be important to recognise these differences if the hair root is used in biochemical screening tests. We have used a new simple technique for measuring the root diameter using an image-splitting eye-piece.
头发生长测量是营养状况的敏感指标，我们已经评估了它们在围产期的价值。对114名婴儿出生时生长毛囊的比例及其直径进行了研究，并在3周后对29名低体重儿进行了重复研究。宫内营养不良导致毛囊更细，但出生后的变化与营养无关，这些测量在这一时期的喂养研究中并无用处。出生时，胎龄和性别会影响毛囊，如果将毛囊用于生化筛查测试，认识到这些差异可能很重要。我们使用了一种新的简单技术，通过图像分割目镜测量毛囊直径。
