Births with known time to pregnancy (TTP) during the period 1989-2007 (n=17,114) were analyzed to investigate associations between TTP and pregnancy outcome among couples that conceived spontaneously. The adjusted odds ratio (95% confidence interval) for poor neonatal health, including low Apgar score, low umbilical vein pH, and need for neonatal intensive care, was 1.51 (1.09-2.09) in women who had a TTP of 25-36 months and 1.60 (1.18-2.19) in women who had a TTP of >or=37 months compared with women with a TTP of 0-6 months.
对 1989 年至 2007 年间已知受孕时间（TTP）的分娩进行分析，以研究在自然受孕的夫妇中 TTP 与妊娠结局之间的关系。与 TTP 为 0-6 个月的妇女相比，TTP 为 25-36 个月的妇女和 TTP 为≥37 个月的妇女不良新生儿健康（包括低 Apgar 评分、脐静脉 pH 值低和需要新生儿重症监护）的调整比值比（95%置信区间）分别为 1.51（1.09-2.09）和 1.60（1.18-2.19）。
