背景资料。青春期怀孕与不良结局的过度风险有关，包括低出生体重和早产，这种联系是否只是反映了大多数怀孕青少年的有害社会人口环境，或者生物上的不成熟是否也是因果关系尚不清楚，方法。为了确定年轻是否会带来怀孕不良后果的内在风险，我们对犹他州134,088名13岁至24岁的白人女孩和妇女进行了分层分析，她们在1970年至1990年期间生下了单身的第一个孩子。为了剔除婚姻状况、教育程度和产前护理充分性的混杂影响，整个研究人群的调整后相对风险被计算为各阶层特定风险的加权平均值。在接受过充分产前护理、受教育程度与其年龄相匹配的白人已婚母亲中，年轻的青少年母亲(13至17岁)的风险显著更高(P
Background. Pregnancy in adolescence is associated with an excess risk of poor outcomes, including low birth weight and prematurity, Whether this association simply reflects the deleterious sociodemographic environment of most pregnant teenagers or whether biologic immaturity is also causally implicated is not known,Methods. To determine whether a young age confers an intrinsic risk of adverse outcomes of pregnancy, we performed stratified analyses of 134,088 white girls and women, 13 to 24 years old, in Utah who delivered singleton, first-born children between 1970 and 1990. Relative risk for subgroups of this study population was examined to eliminate the confounding influence of marital status, educational level, and the adequacy of prenatal care, The adjusted relative risk for the entire study group was calculated as the weighted average of the stratum-specific risks.Results. Among white married mothers with educational levels appropriate for their ages who received adequate prenatal care, younger teenage mothers (13 to 17 years of age) had a significantly higher risk (P
