这封信的作者在几年的时间里检查了来自加勒比海和中南美洲的2500多名儿童的头发样本，这些儿童表现出不同程度的蛋白质-热量营养不良（PCM），在这里他们列出了一些一般性的观察结果：发色减退（毛发色素异常和减少）是一种可变的体征;它在许多严重的夸希奥科病病例中不存在。如果在恶性营养不良中出现，则很明显，但在消瘦症中不太常见，也不太明显。它不能作为儿童目前病情的诊断指南，因为它是在头发显示其影响之前1-3个月发生的某种营养损害的迹象。如果了解它的局限性，它对社区调查是有用的，它是一个容易看到的标志，可以由辅助医务人员记录。在恶性营养不良的严重性或慢性化方面，不同的色度几乎没有预测价值。毛干提供了一个容易获得的营养史，因为营养不良的持续时间可以从色素异常区域的长度计算出来（头发以每天0.2 mm的速度生长）。反复出现的发色变浅的条带表明有明显的营养不良时期。应牢记可能影响图片的当地条件或习惯，例如来自太阳和盐空气的风化，干燥多尘的条件，或使用染发剂或油。作为营养状况的最新指标，发根优于毛干[thisBulletin，1972，v. 69，摘要236，1233，2471]。F.

The writers of this letter have examined, over a period of several years, hair samples from more than 2500 children from the Caribbean and Central and South America who showed different degrees of protein-calorie malnutrition (PCM), and here they set down some general observations.Hypochromotricia (abnormal and reduced hair pigmentation) is a variable sign; it is not present in many severe cases of kwashiorkor. If present in kwashiorkor it is obvious, but it is less frequent and less obvious in marasmus.It is not useful as a diagnostic guide to a child's present condition, since it is an indication of some nutritional insult which occurred 1-3 months before showing its effect in the hair. It is useful for community surveys if its limitations are understood, and it is a sign which is easily visible and can be recorded by paramedical personnel. The different shades of colouration have little predictive value in kwashiorkor in relation to severity or chronicity. The hair shaft provides a readily available nutritional history since the duration of a period of malnutrition may be calculated from the length of the area of dyspigmentation (hair grows at a rate of 0.2 mm per day). Repeated bands of lightened hair colour suggest distinct periods of malnutrition. Local conditions or habits which may affect the picture should be borne in mind,e.g. weathering from sun and salt air, dry dusty conditions, or the use of hair dyes or oils. Hair roots are preferable to hair shafts as a more recent indication of nutritional status [thisBulletin, 1972, v. 69, abstrs 236, 1233, 2471]. F. I.C. Apted.
