Nearly 80% of gay, lesbian, bisexual and transgender (GLBT) Australians suffered at least one episode of intense anxiety in the past year, and more than 25% were diagnosed with, or treated for, an anxiety disorder, a national study has found.

The survey of almost 4,000 GLBT people aged 16 to 89 found many “occasionally” or “usually” hid their sexuality or gender identity for fear of violence or discrimination: 44% in public and 33.6% when accessing services.

The most common types of violence reported by participants were non-physical, from verbal abuse (25.5 per cent), to harassment (15.5 per cent), to threats of physical violence (8.7 per cent) and written abuse (6.6 per cent).

Thirty-one percent of participants said they had not revealed their sexuality or gender identity to their GP. People aged 16 to 24 were most likely to hide their sexuality or gender identity.

The study, by La Trobe University’s Australian Research Centre in Sex, Health and Society and Gay and Lesbian Health Victoria, is the second in a series looking at the health and wellbeing of GLBT Australians.

La Trobe University Research Fellow, Liam Leonard, said that “while the research documents show an increased acceptance of GLBT people and marginal improvements in their general health, it also shows GLBT people continue to experience much higher levels of abuse and discrimination. A likely outcome of this is the poorer mental health participants had compared with the population at large.

“The most common health conditions among participants were depression and anxiety/nervous disorders.”

The project was supported by Beyond Blue with funds from The Movember Foundation. Chairman of Beyond Blue, Jeff Kennett, said the research “strengthens our resolve to continue our work with this community to reduce discrimination and improve help-seeking. Mid-year … we will be launching an awareness campaign to address some of the disturbing statistics highlighted in this report.” [continue reading…]

Hit by the baby blues

Many Norwegian women postpone pregnancy until they have completed their education and are well established on their career path. This may make them more vulnerable to postpartum depression.

“There are some indications that older, first-time mothers are vulnerable to postpartum depression (PPD), perhaps because they are used to being in control of their own lives: they have completed a long education and established a career before they have children. But you can’t control a baby; on the contrary, you have to be extremely flexible. Several of the women I interviewed said themselves that this contributed to the huge feeling of letdown when things did not turn out as they had planned,” says Silje Marie Haga, who recently defended her doctoral thesis Identifying risk factors for postpartum depressive symptoms: the importance of social support, self-efficacy, and emotion regulation.

International studies have found that teenage mothers are at increased risk of postpartum depression, and previously this group has received extra attention. But in Norway this is a small group. Haga therefore believes that initiatives should now be targeted towards the much larger group of older mothers.

“Having very clear expectations and a great need for control is a risk factor. Those who prepare themselves to a very high degree for how life with the child will be have a hard time when things do not go as planned. So it’s not the need for control in itself, but rather the failure to achieve specific expectations that can trigger a depression. In contrast, women who take a more relaxed approach to motherhood with more undefined expectations cope better with unexpected challenges,” Haga observes.

She stresses that she is not warning women against postponing pregnancy, but that she believes it is vital to be aware of this correlation. This gives an opportunity to launch initiatives targeted towards this group of women so that they acquire more realistic expectations of what lies ahead. [continue reading…]

"The basic idea is that depression and the genes that promote it were very adaptive for helping people—especially young children—not die of infection in the ancestral environment, even if those same behaviors are not helpful in our relationships with other people," says psychiatrist Charles Raison.Credit: iStockphoto

Depression is common enough – afflicting one in ten adults in the United States — that it seems the possibility of depression must be “hard-wired” into our brains. This has led biologists to propose several theories to account for how depression, or behaviors linked to it, can somehow offer an evolutionary advantage.

Some previous proposals for the role of depression in evolution have focused on how it affects behavior in a social context. A pair of psychiatrists addresses this puzzle in a different way, tying together depression and resistance to infection. They propose that genetic variations that promote depression arose during evolution because they helped our ancestors fight infection.

An outline of their proposal appears online in the journal Molecular Psychiatry. [continue reading…]

New way to beat depression

brain activityStimulating the brain with a weak electrical current is a safe and effective treatment for depression and could have other surprise benefits for the body and mind, a major Australian study of transcranial Direct Current Stimulation (tDCS) has found.

Medical researchers from the University of New South Wales (UNSW) and the Black Dog Institute have carried out the largest and most definitive study of tDCS and found up to half of depressed participants experienced substantial improvements after receiving the treatment.

A non-invasive form of brain stimulation, tDCS passes a weak depolarising electrical current into the front of the brain through electrodes on the scalp. Patients remain awake and alert during the procedure.

“We are excited about these results. This is the largest randomised controlled trial of transcranial direct current stimulation ever undertaken and, while the results need to be replicated, they confirm previous reports of significant antidepressant effects,” said trial leader, Professor Colleen Loo, from UNSW’s School of Psychiatry.
