Weight, height, and head circumference measurements of 4,167 Spanish-surnamed school-aged children were compared with similar data from 2,322 non-Spanish surnamed children who resided in the same Denver, Colorado neighborhoods. These data were also compared with data from six other studies. Both male and female Spanish-surnamed children were found to weigh less, be shorter, and have smaller head circumferences than non-Spanish-surnamed children living in the same Denver neighborhoods. The sizes of the children in these two populations residing in lower and lower-middle class neighborhoods were closer to each other than to the sizes of children from middle and upper-middle socioeconomic classes as measured in previous studies or to the sizes of children in the recently published cross-sectional National Center for Health Statistics study. Such comparisons suggest that growth retardation is more a reflection of socioeconomic factors than of ethnic-genetic factors.
对4167名西班牙裔姓氏学龄儿童的体重、身高和头围测量数据，与居住在科罗拉多州丹佛市相同社区的2322名非西班牙裔姓氏儿童的类似数据进行了比较。这些数据还与其他六项研究的数据进行了比较。结果发现，与居住在丹佛相同社区的非西班牙裔姓氏儿童相比，西班牙裔姓氏的男孩和女孩体重更轻、身高更矮、头围更小。与先前研究中测量的中高社会经济阶层儿童的体型或最近发表的美国国家卫生统计中心横断面研究中儿童的体型相比，居住在中低阶层社区的这两个人群中儿童的体型彼此更接近。此类比较表明，生长发育迟缓更多地反映了社会经济因素，而非种族遗传因素。
