从 20 世纪 70 年代末到 90 年代初，来自危地马拉的玛雅家庭移民到美国的数量达到了创纪录的水平。玛雅移民妇女的生育创造了相当数量的玛雅美国儿童。 1999年和2000年测量了5至12岁儿童（n = 431）的身高和坐高。估计腿长并计算坐高比。这些数据与 1998 年测量的居住在危地马拉的玛雅儿童样本 (n = 1,347) 进行了比较。目前，美国玛雅儿童比居住在危地马拉的玛雅儿童平均身高高 11.54 厘米，腿长 6.83 厘米。因此，美洲玛雅人的平均坐高比（即，腿与头部和躯干长度的比例相对较长）明显低于危地马拉玛雅人。这些结果进一步支持了这样的假设：人口的身高和身体比例都是生长环境质量的敏感指标。是。 J.哼。生物。 14:753-761, 2002。(C) 2002 Wiley-Liss, Inc.
Maya families from Guatemala migrated to the United States in record numbers from the late 1970s to the early 1990s. Births to Maya immigrant women have created a sizable number of Maya American children. The height and sitting height of 5 to 12 years children (n = 431) were measured in 1999 and 2000. Leg length was estimated and the sitting height ratio was calculated. These data were compared with a sample of Maya children living in Guatemala measured in 1998 (n = 1,347). Maya American children are currently 11.54 cm taller and 6.83 cm longer-legged, on average, than Maya children living in Guatemala. Consequently, the Maya Americans have a significantly lower average sitting height ratio (i.e., relatively longer legs in proportion to length of the head and trunk) than do the Maya in Guatemala. These results add support to the hypothesis that both the height and body proportions of human populations are sensitive indicators of the quality of the environment for growth. Am. J. Hum.
