Prevalence of depression and anxiety in women with recurrent pregnancy loss and the associated risk factors.

OBJECTIVE

To investigate the prevalence and explore potential risk factors of depression and anxiety in patients with recurrent pregnancy loss (RPL).

METHODS

1138 non-pregnant women aged 20-40 years old who attempted to conceive were invited to complete a questionnaire, including basic information, Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS).

RESULTS

782 RPL women, 218 women with one pregnancy loss and 138 women with no history of pregnancy loss were included in this study. We found that both RPL patients and women with one pregnancy loss had significantly higher SDS and SAS scores than the control group (P = 0.006, 0.003). Furthermore, in RPL patients, those with lower education level (lower than university), lower household income (< 10,000 yuan) and history of induced abortion had significantly higher levels of depression and anxiety. Women with multiple pregnancy losses ( ≥ 3) and no live birth had significantly higher SDS scores. Women who had been married for 3 years or more had a significantly higher SAS score. Logistic regression revealed that lower education level (lower than university) was an independent risk factor for depression (adjusted OR = 1.75, 95% CI 1.10-2.77, P = 0.018) and anxiety (adjusted OR = 1.80, 95% CI 1.04-3.13, P = 0.037), and women with three or more pregnancy losses had increased odds of depression than those with two pregnancy losses (adjusted OR = 1.82, 95% CI 1.15-2.88, P = 0.012).

CONCLUSION

RPL patients are more likely to develop depression and anxiety than women with no history of pregnancy loss. Lower education level and multiple pregnancy losses (≥ 3) appear to be two independent risk factors of depression and anxiety in women with RPL. Women with one pregnancy loss also show a significant higher level for depression and anxiety. Appropriate psychological intervention can be considered for such patients.
