The growth and hematological status of all 152 Eskimo children of Wainwright, AK observed in 1977 are reported and compared with the respective status of the children living there in 1968. Fifty-two children (34%) in the 1977 study were also in the 1968 study. Comparison of height data observed in 1977 with those observed in 1968 reveals that male children less than 11 yr of age and female children ages 3 to 9 yr showed a significant improvement in stature (p less than 0.05). At the same time, an improvement in nutrition was observed among the children in 1977 as evidenced by the marked decrease in anemia for children under 6 yr (p less than 0.001). These changes in growth and hematological status have occurred during a time in which health services were improved, a supplemental nutrition program was instituted, and subsistence food gathering remained high. These changes underscore the contribution of environmental factors rather than of genetic variability to the growth potential of these children.
报告了1977年在阿拉斯加温赖特观察到的152名爱斯基摩儿童的生长和血液学状况，并与1968年居住在那里的儿童的相应状况进行了比较。1977年研究中的52名儿童（34%）也参与了1968年的研究。将1977年观察到的身高数据与1968年观察到的数据进行比较，发现11岁以下男童和3至9岁女童的身高有显著改善（p<0.05）。同时，1977年儿童的营养状况有所改善，6岁以下儿童贫血明显减少证明了这一点（p<0.001）。生长和血液学状况的这些变化发生在卫生服务得到改善、实施了补充营养计划且自给性食物采集量仍然很高的时期。这些变化强调了环境因素而非基因变异对这些儿童生长潜力的贡献。
