Psychological factors influencing choice of prenatal diagnosis in Chinese multiparous women with advanced maternal age.

OBJECTIVES

To investigate the psychological predictors in Chinese multiparous pregnant women of advanced maternal age (AMA) for choosing aneuploidy screening or diagnostic testing.

METHODS

A total of 84 pregnant women of AMA were consecutively enrolled from Renming Hospital, Wuhan University. All participants completed three questionnaires: Zung Self-Rating Anxiety Scale (SAS), Zung Self-Rating Depression Scale (SDS), and Pregnancy Stress Rating Scale (PSRS). Demographic information and the choice of noninvasive prenatal testing (NIPT) versus invasive prenatal diagnosis (PND) were also collected.

RESULTS

Thirty-seven chose to have invasive PND, and 47 chose NIPT. Choosing invasive PND, as opposed to NIPT, was associated with lower educational background (χ = -2.269, p = .023), higher SAS scores (47.62 ± 7.96 versus 44.21 ± 6.10, p = .029), and higher SDS scores (50.41 ± 9.80 versus 45.96 ± 11.05, p = .058). Logistic regression analysis further showed that the decisive predictors for invasive PND are SAS (OR =1.106, p = .008) scores, scores of factor 3 in PSRS and the stress from changes of shape and motility (OR =0.471, p = .038). Subgroup analysis showed that women with previous negative pregnancy experience had higher scores in factor 2-stress (guarantee of maternal-fetal safety: 1.96 ± 0.63 versus 2.49 ± 0.65, p = .004) and total PSRS scores (1.60 ± 0.4 versus 1.83 ± 0.31, p = .044) than those without. Additionally, unemployment post pregnancy was associated with marginally significant higher PSRS scores (p = .083).

CONCLUSIONS

The decision for invasive PND might be swayed by anxiety and attenuated by pregnancy stress originating from worry about changes in fetal shape and motility (measured by SAS and factor 3 score of PSRS, respectively).
