To test the hypothesis that chromium deficiency may be cumulative with age and increasing parity, hair chromium levels were measured in 432 women at delivery. Although the levels in general were lower than those found in nonpregnant women there was no correlation between hair chromium level and age or number of pregnancies. Hair zinc levels were also measured to rule out zinc deficiency as a factor.
为验证铬缺乏可能随年龄增长和生育次数增加而累积的假说，对432名分娩期妇女的头发铬水平进行了测量。尽管总体水平低于非孕妇，但头发铬水平与年龄或妊娠次数之间并无关联。同时也测量了头发锌水平，以排除锌缺乏这一因素。
