Women who are depressed tend to have more sex than their happier counterparts, even if they aren't in a relationship.
The finding is based on a survey of 107 depressed and non-depressed Aussie women who were in relationships.
The researchers found that not only did women suffering from mild to moderate depression have more active sexual lives, but also had sexually liberated attitudes, a bigger variety of sexual experiences, but also if single, they also tended to indulge in casual sex.
"It was more sex and more of everything from kissing to petting, foreplay and intercourse," News.com.au quoted lead author Dr Sabura Allen, as saying.
"We knew this anecdotally from clinical samples but this is the first time it's been shown in research," she added.
Dr Allen said that the reason depressed women were more likely to have sex was that it helps them feel secure.
"When people are depressed they feel more insecure about their relationships and concerned that their partner may not care about them or find them valuable. Having sex helps them feel that closeness and security," she said.
The study, soon to be published in a British medical journal, was presented at the International Congress on Women's Mental Health in Melbourne.
