In 1979 the Centers for Disease Control conducted a household probability survey of reproductive aged women living in 51 selected US countries on the US-Mexico border. Information on the incidence of breastfeeding for the period 1971-1979 was analyzed on 345 Anglo women and 689 Hispanic women of Mexican origin. Results indicated that the Anglos are following the national trend of increased breastfeeding, but Hispanics show no indication of an increase in the practice of breastfeeding.
1979年，疾病控制中心对居住在美国与墨西哥边境51个选定县的育龄妇女进行了一次家庭概率调查。对345名盎格鲁妇女和689名墨西哥裔西班牙妇女1971 - 1979年期间的母乳喂养发生率信息进行了分析。结果表明，盎格鲁妇女遵循全国母乳喂养增加的趋势，但西班牙裔妇女没有显示出母乳喂养行为增加的迹象。
