PainRelief.com: What is the background for this study?

Response: Across the world, women are twice as likely as men to experience depression, often with more severe physical symptoms. This difference is especially noticeable during their reproductive years and affects hundreds of millions of women. While links between mental and reproductive health are known, they are not fully understood.

In our study, we wanted to figure out the relationship and directionality between depression and menstrual pain (dysmenorrhea). It is kind of like trying to solve a very complex puzzle. Instead of doing experiments directly on people, we used a clever approach called Mendelian Randomization. This method works like nature’s experiment. It uses genetic data, like tiny instructions in our DNA, to see if having certain genes linked to depression also makes people more likely to have menstrual pain. This helps us find patterns and identify cause-and-effect without the need to test it directly on people. It is like looking for clues to see how the pieces of this complex puzzle all fit together.

PainRelief.com: What is the background for this study?

Response: Although pain is one of the most common reasons for seeking medical help, providing adequate treatment can be challenging due to its subjective nature. When healthcare providers’ pain management decisions rely on subjective judgment, they are susceptible to biases.

PainRelief.com: What are the main findings?

Response: Our study, which analyzed over 21,000 patient records from the United States and Israel, found a significant sex bias in pain management at emergency departments. We found that female patients are consistently less likely to receive pain relief prescriptions compared to male patients with similar complaints (around 10% difference). This bias persists across different ages, pain levels, and physician sex, indicating a systemic issue. Female patients’ pain scores are less frequently recorded, and they spend more time in the emergency department than male patients. In a controlled experiment involving 109 nurses, we found that pain was rated as less intense if the patient was said to be female rather than male, which supports our hypothesis that healthcare providers are susceptible to stereotypical beliefs about women’s pain and expect them to act “hysterically” and exaggerate their pain reports.
