目的：确定第一代和在美国出生的墨西哥裔美国母亲中低出生体重、早产和宫内发育迟缓的年龄相关模式。我们对伊利诺伊州墨西哥裔美国婴儿(1989-1991)及其母亲(1956-1976)的跨代数据集进行了分层分析，并附上了美国人口普查收入信息。在伊利诺伊州库克县，已确定的(第二代或更高代)美国出生的墨西哥裔美国妇女(N=2,006)出生体重低(2,500克)的比率为6.2%，而第一代美国出生的墨西哥裔美国妇女(N=1,450)的低出生体重(<；2,500克)比率为4.8%，RR=1.3(1.0-1.6)。在这两个亚组中，低出生体重、早产和宫内发育迟缓的发生率并没有随着母亲年龄的增加而增加。第一代出生在美国的30-35岁墨西哥裔美国女性(N=159)出生体重低，为3.1%，而青少年女性为4.2%(N=386)，RR=0.8(0.3-2.0)。已确定的30-35岁美国出生的墨西哥裔美国女性(N=330)出生体重低，为4.9%，而青少年女性(N=459)为7.4%，RR=0.7(0.4-1.2)。在美国出生的墨西哥裔美国母亲中，没有证据表明他们终生居住在低收入社区，在30-35岁之前，随着年龄的增长，低出生体重率总体上呈下降趋势。在第一代和在美国出生的15-35岁墨西哥裔美国女性中，低出生体重、早产和宫内发育迟缓的比率不会随着年龄的增长而增加。这一趋势在终生居住在低收入社区的两代女性中都存在。
To determine the age-related patterns of low birth weight, preterm birth, and intrauterine growth retardation among first generation and established US-born Mexican-American mothers. We performed stratified analyses on an Illinois transgenerational dataset of Mexican-American infants (1989-1991) and their mothers (1956-1976) with appended U.S. census income information. In Cook County, Illinois established (second or higher generation) US-born Mexican-American women (N = 2,006) had a low birth weight (< 2,500 g) rate of 6.2% compared to 4.8% for first generation US-born Mexican-American women (N = 1,450), RR = 1.3 (1.0-1.6). In both subgroups, low birth weight, preterm, and intrauterine growth retarded components rates did not increase with advancing maternal age. First generation 30-35 year old US-born Mexican-American women (N = 159) had a low birth weight rate of 3.1% compared to 4.2% for their teen counterparts (N = 386), RR = 0.8 (0.3-2.0). Established 30-35 year old US-born Mexican-American women (N = 330) had a low birth weight rate of 4.9% compared to 7.4% for their teen counterparts (N = 459), RR = 0.7 (0.4-1.2). There was no evidence of weathering among US-born Mexican-American mothers with a lifelong residence in lower income neighborhoods, with a general downward trend in low birth weight rates with increasing age until age 30-35. Rates of low birth weight, preterm birth, and intrauterine growth retardation do not increase with advancing age among first generation and established US-born 15-35 year old Mexican-American women. This trend persists among both generations of women with a lifelong residence in lower income neighborhoods.
