The smoking practices of a national sample of Mexican-American mothers and the resulting effects of those practices on birth weight were examined. Data were from the Hispanic Health and Nutrition Examination Survey conducted by the U.S. National Center for Health Statistics during 1983-1984. We found that 24% of the mothers had smoked during their pregnancy, with a mean of 11 cigarettes per day. Infants of these women weighed 101 g less at birth than did infants of nonsmoking mothers and had a low birth weight rate of 8.0% compared with the 5.1% low birth weight rate for the sample as a whole. Multiple regression results indicate a 7.4 g decrease in birth weight for each cigarette smoked per day during pregnancy. Cultural factors that promote a low birth weight rate for Mexican-Americans that is comparable to that of non-Hispanic whites despite increased rates of poverty and inadequate health care do not protect against the insidious effects of cigarette smoking.
对一组具有全国代表性的墨西哥裔美国母亲的吸烟行为及其对出生体重的影响进行了研究。数据来自美国国家卫生统计中心在1983年至1984年期间进行的西班牙裔健康与营养检查调查。我们发现，24%的母亲在孕期吸烟，平均每天吸11支烟。这些女性的婴儿出生时体重比不吸烟母亲的婴儿轻101克，低出生体重率为8.0%，而整个样本的低出生体重率为5.1%。多元回归结果表明，孕期每天每多吸一支烟，出生体重就会减少7.4克。尽管贫困率上升且医疗保健不足，但促使墨西哥裔美国人的低出生体重率与非西班牙裔白人相当的文化因素，并不能抵御吸烟的潜在影响。
