Final answer:
Bisexual women have an increased risk of experiencing intimate partner violence (IPV), especially when partnered with men (men vs a woman), which could contribute to a higher risk of perinatal mood and anxiety disorders (PMADs) in this population.
Step-by-step explanation:
The question revolves around the risk of perinatal mood and anxiety disorders (PMADs) among bisexual women and how their risk factors vary depending on the gender of their partner. Relevant data shows that intimate partner violence (IPV) rates are generally higher among LGBTQ individuals compared to their non-LGBTQ counterparts. Specifically, 61 percent of bisexual women report experiencing IPV, significantly higher than other women. Given these statistics, it can be inferred that bisexual women may have an increased risk of PMADs when partnered with men due to the higher likelihood of experiencing IPV, which is a risk factor for PMADs.
