Abstract：
OBJECTIVE: To obtain evidence of the clinical validity of the nursing diagnosis (ND) risk for disturbed maternal-fetal dyad in high-risk pregnancy.
METHODS: Causal validation of the ND through a case-control study performed in a university hospital with 155 high-risk pregnant women: 31 cases and 124 controls. A causal association was found between the ND etiological factors and the occurrence of disruption of the symbiotic maternal-fetal dyad; an association was verified when the etiological factor presented a p-value <0.05 and odds ratio >1.
RESULTS: The risk factor absent-inadequate prenatal care; populations at risk, such as young-advanced maternal age and economically disadvantaged pregnant women; and association conditions, such as maternal conditions and compromised fetal oxygen transport, increased the outcome likelihood. The associated condition maternal illnesses appeared as a protective factor.
CONCLUSIONS: Evidence of clinical validity of the ND risk for disturbed maternal-fetal dyad was obtained, and an association between etiological factors and disruption of the symbiotic maternal-fetal dyad was found.
CONCLUSIONS: The results contribute to advance scientific knowledge in nursing teaching, research, and practice and support the nursing process in high-risk pregnancies.

摘要：
目的：获取高危妊娠母胎二联病变护理诊断（ND）风险的临床有效性证据。
方法：通过在大学医院进行的病例对照研究对ND进行因果验证，该研究有155名高危孕妇：31例和124名对照。在ND病因学因素与共生母胎二叉破坏的发生之间发现了因果关系；当病因学因素呈现p值<0.05且比值比>1时，证实了这种关联。
结果：缺乏产前护理的危险因素；高危人群，例如年事已高的孕妇和经济上处于不利地位的孕妇；和协会条件，例如母体状况和胎儿氧转运受损，增加了结果的可能性。相关的孕产妇疾病似乎是一个保护因素。
结论：获得了母胎二位紊乱的ND风险的临床有效性证据，并发现了病因学因素与共生母胎二叉破坏之间的关联。
结论：结果有助于提高护理教学中的科学知识，研究,实践和支持高危妊娠的护理过程。
