Women who experienced six or more symptoms of post-traumatic stress disorder (PTSD) at some point in life have a greater risk of developing ovarian cancer compared to women who never had any PTSDs, says a new study.

The study published in the journal Cancer Research, also found that the link between PTSD and ovarian cancer remained for the most aggressive forms of ovarian cancer.

“In light of these findings, we need to understand whether successful treatment of PTSD would reduce this risk and whether other types of stress are also risk factors for ovarian cancer,” said co-author Andrea Roberts from Harvard University.

To better understand how PTSD may influence ovarian cancer risk, researchers analysed data from the Nurses’ Health Study II, which tracked the health of tens of thousands of women between 1989-2015 through biennial questionnaires and medical records.

Participants were asked about ovarian cancer diagnosis in each questionnaire, and information was validated through a review of medical records.

In 2008, 54,763 Nurses’ Health Study II participants responded to a supplemental questionnaire focused on lifetime traumatic events and symptoms associated with those events.

Women were asked to identify the event they considered the most stressful, and the year of this event. They were also asked about seven PTSD symptoms they may have experienced related to the most stressful event.

Based on the responses, women were divided into six groups: no trauma exposure; trauma and no PTSD symptoms; trauma and one to three symptoms; trauma and four and five symptoms; trauma and six-seven symptoms; and trauma, but PTSD symptoms unknown.

After adjusting for various factors associated with ovarian cancer, including oral contraceptive use and smoking, the researchers found that women who experienced six-seven symptoms associated with PTSD were at a significantly higher risk of ovarian cancer than women who had never been exposed to trauma.

Women with trauma and four-five symptoms were also at an elevated risk, but the risk did not reach statistical significance.

The study also showed that women who experienced six-seven symptoms associated with PTSD were at a significantly higher risk of developing the high-grade serous histotype of ovarian cancer — the most common and aggressive form of the disease. (IANS)

More than 3.3 million women in the US had unwanted and forced first sexual intercourse experience, a new study suggests.

The study, published in the journal JAMA Internal Medicine, estimates that one in 16 US women had an unwanted first sexual intercourse experience that was physically forced or coerced.

The #MeToo movement has highlighted how frequently women experience sexual violence. However, no recent studies have assessed the prevalence of forced sex during girls’ and women’s first sexual encounter or its health consequences.

In an analysis of nationally representative survey data of 13,310 women, 6.5 per cent of the respondents reported a forced first sexual intercourse encounter, which is equivalent to more than 3.3 million women between the ages of 18 and 44.

The average age for women at the time of the forced encounter was 15-and-a-half compared with 17-and-a-half for those reporting a voluntary first sexual intercourse experience, according to researchers from Harvard University in the US.

The average age of the assailant at a first forced sexual intercourse was 27 as compared with the 21 of the partner in a voluntary first sexual experience, the study said.

According to the survey, women with a forced first sexual intercourse experience were more likely to have an unwanted first pregnancy or abortion, as well as other gynaecological and general health problems.
