The Illinois Department of Public Health, in cooperation with the Centers for Disease Control (CDC), monitors trends in the prevalence of prenatal risk factors that are major predictors of infant mortality and low birth weight (LBW). Analyzed data from CDC are available to the department annually. During 1988, a total of 26,767 records of Illinois women giving birth were submitted to CDC. These surveillance data support the fact that women older than 30 years who smoke and enter pregnancy underweight are at greatest risk of delivering LBW babies. Overall, 13.9 percent of underweight smokers had LBW infants compared with 8 percent of underweight nonsmokers. Prevalence of LBW among underweight and smoking women older than 34 years was much higher (29.6 percent) than among those between ages 30 and 34 (15.2 percent). The prevalence of LBW decreased as the pregravid weight increased among normal weight smokers (10 percent) and overweight smokers (8.6 percent).
伊利诺伊州公共卫生部与疾病控制中心（CDC）合作，监测作为婴儿死亡率和低出生体重（LBW）主要预测指标的产前风险因素的流行趋势。该部门每年都能获取来自疾病预防控制中心的分析数据。1988年期间，伊利诺伊州共有26,767名分娩妇女的记录提交给了疾病预防控制中心。这些监测数据证实了这样一个事实，即30岁以上吸烟且怀孕时体重过轻的女性生出低体重婴儿的风险最大。总体而言，体重过轻的吸烟者中有13.9%生出低体重婴儿，而体重过轻的非吸烟者这一比例为8%。34岁以上体重过轻且吸烟的女性中低出生体重的发生率（29.6%）远高于30至34岁的女性（15.2%）。在正常体重吸烟者（10%）和超重吸烟者（8.6%）中，低出生体重的发生率随着孕前体重的增加而降低。
