Advanced prenatal genomic technologies can identify risks for adult-onset (AO) conditions in the fetus, challenging the traditional purpose of prenatal testing. Professional guidelines commonly support disclosure of high-penetrance AO actionable conditions, yet attitudes of women/parents to these findings and factors affecting their attitudes are understudied.
We explored 941 (77% response rate) postpartum women's attitudes towards receiving prenatal genetic information, and associations of sociodemographic, medical and psychological characteristics with their choices, focusing on AO conditions.
Women largely support the disclosure of actionable AO findings (58.4%), in line with professional guidelines. A third of the women also supported the disclosure of non-actionable AO conditions. Stronger religious observance (p < 0.001) and higher psychological distress (p = 0.024) were associated with decreased interest in receiving actionable AO conditions, whereas higher concern for fetal health yielded increased interest (p = 0.032). Attitudes towards disclosure were strongly associated with women's perceived benefit of such information for their own, partner's, and future child's health. Termination of pregnancy based on such information received very little support.
In-light of the demonstrated understanding of nuanced genetic information and the observed diversity in attitudes, a culturally competent opt-in/out policy could be considered. If full-disclosure is practiced, support should be provided to those expressing higher levels of distress.
先进的产前基因组技术可以识别胎儿成年发病(AO)疾病的风险,这对产前检测的传统目的提出了挑战。专业指南通常支持披露高外显率 AO 可采取行动的疾病,但女性/父母对这些发现的态度以及影响他们态度的因素研究不足。
我们探讨了 941 名(77%的回复率)产后女性对接受产前遗传信息的态度,以及社会人口统计学、医疗和心理特征与她们对 AO 疾病的选择的关联。
女性普遍支持披露可采取行动的 AO 发现(58.4%),符合专业指南。三分之一的女性也支持披露非可采取行动的 AO 疾病。更强的宗教信仰(p<0.001)和更高的心理困扰(p=0.024)与对接受可采取行动的 AO 疾病的兴趣降低有关,而对胎儿健康的更高关注则产生了更大的兴趣(p=0.032)。对披露的态度与女性对这些信息对自己、伴侣和未来孩子健康的益处的看法密切相关。基于这些信息终止妊娠的做法几乎没有得到支持。
鉴于已经证明了对复杂遗传信息的理解,以及观察到的态度多样性,可以考虑制定一种具有文化敏感性的选择加入/退出政策。如果实行全面披露,应该为那些表达更高水平困扰的人提供支持。
