To explore the intergenerational birth-weight patterns of the direct female descendants of Mexican-American women.
This is a population-based study.
Stratified analyses were performed on a transgenerational dataset of 1956-1975 and 1989-1991 Illinois computerized vital records of Mexican-American infants.
Among the descendants of generation 1 US-born Mexican-American women (n=1,940), generation 3 females had a birth weight equivalent to that of their generation 2 mothers, (3294 g vs 3283 g); generation 3 infants with unmarried mothers had a birth weight 121 g less than that of generation 2 infants born to unmarried mothers (3163 g vs 3284 g, P<.01); and generation 3 female infants born to teenaged women had a birth weight 70 g less than that of their generation 2 mothers who were born to teenaged women (3178 g vs 3248 g, P<.01). Among the descendants of generation 1 Mexican-born women (n=1,017), generation 3 females had a birth weight equivalent to that of their generation 2 mothers (3335 g vs 3363 g); generation 3 infants with teenaged mothers had a birth weight 108 g less than that of generation 2 infants with teenaged mothers (3264 g vs 3372 g, P<.01).
An intergenerational rise in birth weight does not occur among the direct female descendants of Mexican-American women.
探讨墨西哥裔美国女性的直系女性后代的代际出生体重模式。
这是一项基于人群的研究。
对1956 - 1975年以及1989 - 1991年伊利诺伊州墨西哥裔美国婴儿的计算机化生命记录的跨代数据集进行分层分析。
在第一代美国出生的墨西哥裔美国女性的后代（n = 1940）中，第三代女性的出生体重与其第二代母亲相当（3294克对3283克）；未婚母亲所生的第三代婴儿的出生体重比未婚母亲所生的第二代婴儿轻121克（3163克对3284克，P <.01）；青少年女性所生的第三代女婴的出生体重比青少年女性所生的第二代母亲轻70克（3178克对3248克，P <.01）。在第一代墨西哥出生的女性的后代（n = 1017）中，第三代女性的出生体重与其第二代母亲相当（3335克对3363克）；青少年母亲所生的第三代婴儿的出生体重比青少年母亲所生的第二代婴儿轻108克（3264克对3372克，P <.01）。
墨西哥裔美国女性的直系女性后代中未出现出生体重的代际上升。
