Age changes in the livers of Costa Ricans have been compared with those of native and Hawaii Japanese and U.S. caucasians. In the case of the U.S. caucasians and Costa Ricans, the decrease in the number of hepatic cells is similar up to 70 years of age, but after 80 years of age the decrease is more marked in the Costa Ricans. The difference in the process of senile change among these four groups suggests that the environmental, especially nutritional, conditions during their childhood and adolescence play an important role.
已将哥斯达黎加人的肝脏年龄变化与当地人和夏威夷日本人以及美国白种人的肝脏年龄变化进行了比较。就美国白种人和哥斯达黎加人而言，直至70岁肝细胞数量的减少情况相似，但80岁以后哥斯达黎加人的肝细胞数量减少更为明显。这四组人群衰老变化过程的差异表明，他们童年和青少年时期的环境，尤其是营养状况，起着重要作用。
