Cross Sectional Study of Prenatal Diagnosis Uptake Among Individuals With Genetic Conditions.
PubMed 文献 · Prenat Diagn · 2026-04-15

该横断面研究分析了2011至2024年间分娩的遗传病个体,评估其产前诊断检测率及新生儿阳性发现。283例中仅25例(8.8%)接受产前诊断检测,其中24例(96%)针对母体遗传病。产前诊断组母体遗传病遗传率48%,未产前诊断组为18.6%;产前诊断组常染色体隐性病比例低于未检测组(8% vs. 38%,p=0.0028)。

要点

  • 遗传病个体产前诊断检测率低,283例中仅8.8%接受检测。
  • 产前诊断多针对母体遗传病,占检测者的96%。
  • 常染色体隐性病在未检测组中比例更高。

核心结论

  • 尽管该队列遗传病传递风险升高,产前诊断检测率仍显著偏低。

研究设计与样本

  • 横断面研究,纳入2011至2024年间分娩的遗传病个体,共283例。

主要发现

  • 283例中25例(8.8%)接受产前诊断检测,其中24例(96%)针对母体遗传病。
  • 产前诊断组母体遗传病遗传率为48%,未产前诊断组为18.6%。
  • 产前诊断组常染色体隐性病比例低于未检测组(8% vs. 38%,p=0.0028)。

临床怎么用

  • 对遗传病个体应加强产前诊断咨询,以支持围产期规划和胎儿长期健康管理。

局限性

  • 需进一步研究评估遗传病个体接受诊断检测的障碍与态度。

OBJECTIVE: Prenatal diagnostic genetic testing allows for early identification of significant fetal conditions and enables informed decision-making regarding management options. The aim of this study was to assess prenatal testing practice among individuals with genetic conditions. METHOD: This is a cross-sectional study of maternal and fetal outcomes among individuals with genetic conditions, who delivered between 2011 and 2024. The primary outcomes were the rates of prenatal diagnostic testing and positive neonatal findings. RESULTS: Of 283 cases, 25 (8.8%) individuals underwent prenatal diagnostic testing, of which 24 (96%) specifically tested for the maternal genetic condition. The maternal condition was inherited by 48% of those undergoing prenatal diagnostic testing versus 18.6% of those who underwent post-natal genetic testing. The group that underwent prenatal diagnostic testing had a smaller proportion of autosomal recessive conditions than those who did not undergo diagnostic testing (8% vs. 38%, p = 0.0028). CONCLUSION: Despite an elevated risk of genetic condition transmission in this cohort, the rate of prenatal diagnostic testing was notably low. Prenatal diagnostic testing has significant implications for perinatal planning and long-term health of the fetus. Further studies should evaluate barriers to and attitudes toward diagnostic testing in individuals with genetic conditions.
