Separate and cumulative effect of risk and protective factors associated with suicidal ideation among Chinese infertile couples: a cross-sectional study

Our findings indicate that infertility-related pressure, anxiety, depression, resilience and marital quality are associated with suicidal ideation among infertile couples. Specifically, higher risk factor index is linked to increased odds of SI in both genders, with females showing a stronger association. And higher protective factor index is associated with reduced odds of SI in females, though this effect is not significant in males. Therefore, interventions targeting the reduction of infertility-related pressure, anxiety, and depression, coupled with the enhancement of resilience and marital quality, may effectively mitigate the risk of suicidal ideation in this population.
