Factors related to indecisive attitudes toward non-invasive prenatal testing among women of reproductive age in Japan.

Abstract

This study aimed to investigate the factors related to indecisive attitudes toward noninvasive prenatal testing (NIPT) among nonpregnant women of reproductive age. We conducted an online survey involving nonpregnant Japanese women aged 20-49 years. The questionnaires consisted of a hypothetical question about whether they would decide to undergo NIPT if they were to become pregnant, and responses with "unsure" were defined as indecisive attitudes. Of 1250 participants, 412 (33%) held indecisive attitudes on whether to undergo NIPT. Multivariable logistic regression analysis demonstrated indecisive attitudes were related to a low level of knowledge about prenatal testing (adjusted odds ratio [AOR] 3.89) and preferences for family-driven decisions (AOR 1.44) instead of provider-driven. Even though the NIPT is widespread, many nonpregnant women of reproductive age are unable to decide whether to undergo the NIPT or not. Hence, indecisive women toward NIPT require adequate information and communication about future NIPT among their families prior to conception. Therefore, preconception support of providing adequate information about testing and facilitating communication regarding future NIPT among women and their family members may help indecisive women make autonomous decisions on NIPT.
