HIV/AIDS
and the human psyche
Do men and
women react differently when
they are diagnosed with HIV/ AIDS? The
answers to these questions raise important implications
for health care workers.
While much research
focuses on the psychological implications of being diagnosed with
HIV/ AIDS, very little research has been done on the role of gender. Do
men and women differ in their response to the diagnosis? And if they differ,
what does that tell us?

body maps were painted by HIV-positive women from Khayelitsha as part
of an outreach programme run by the AIDS and Society Research Unit
at the University of Cape Town. - Photographed by Alwyne Todd.
This question was investigated
by Dr Ben Olley, who was the recipient of last year's prestigious
Africa Research Fellowship. He performed his work in Prof. Dan Stein's
Anxiety and Stress Disorders Research Unit at the Medical School
of the University of Stellenbosch and has since then returned to his home
country, Nigeria..
Dr Soraya Seedat, a co-investigator on the project, says HIV/ AIDS is usually associated with
high rates of psychiatric and emotional problems, in addition to its negative
social impact. Research has found that these problems contribute to people
not sticking to their drug regimens. It can even speed up the progression
of the disease and hasten the death of a patient.
"Most of the existing
research has been conducted in the developed world and very little or no
gender differences have been reported. However, women in the developing
world generally face more stigmatization and suffer more negative life
events than men, leading us to suspect that being diagnosed HIV-positive
could lead to more psychological problems among women," she explains.
Gender
divide
The study
team assessed 149 newly diagnosed HIV/ AIDS patients (44 male and
105 female) attending an infectious diseases clinic at the Tygerberg Hospital.
The team used well-known psychiatric questionnaires to assess the
patients. The most frequent diagnosis was depression (34,9%) followed
by dysthymic disorder (21,5%) (see box for an explanation of this disorder).
Interestingly, there was no difference between the rates of depression
in the two genders. "This differs from our studies
done in HIVnegative populations, where women are at least twice more
likely to develop depression," says Dr Seedat.
This is where the similarity between the men and women ended. The researchers
found that the women were more likely to suffer from post-traumatic stress
disorder (PTSD), while the male patients were significantly more likely
to abuse alcohol and have risky sex. "We're not
sure why women more frequently develop PTSD. Hormonal and neurodevelopmental
factors may play a role but there isn't enough evidence to allow
us to draw any conclusions," she explains.
Why are men more likely
to abuse alcohol and have risky sex? "In our experience, men are
more likely to 'externalise' their distress. An interesting
possibility is that they could have been infected with HIV as a result
of their alcohol abuse.
Another possibility is
that they could use alcohol as a coping mechanism after becoming HIV-positive
- almost 'self-medicating', says Dr Seedat.
Implications for health
Dr Seedat says HIV-positive
women are a high-risk population for developing depression. Studies by
other researchers concluded that HIV-positive women are four times as
likely as HIV-negative women to develop depression.
"So
much focus is given to the physical aspects of the disease, but I really
believe that a mental health evaluation should form part of the general
health assessment of the HIV-positive patient.
"Although more careful
evaluation is needed, our results suggest that maybe our approach to treatment
needs to be different for men than for women.
"Women have a hormonal
cycle that may influence their response to medication - this includes medication
for physical and mental health problems," Dr Seedat says.
Did
you know?
Depression is categorized
as a major mood disorder. It's more severe and occurs in episodes,
hereas dysthymic disorder is a low grade mood disorder. Dysthymic
disorder is a more chronic, persistent, but usually less severe form
of depression.
AFRICA
RESEARCH FELLOWSHIP
The
Africa Research Fellowship is a brainchild of the previous President
of the MRC, Dr Malegapuru Makgoba.
He described
this programme as an integral component of Research Capacity Development
at the MRC.
"Its
focus is building interaction and research capacity within Africa
and between African scientists," he said.
He also
viewed the Fellowship as one way in which the MRC would integrate
with its sister institutions and the many health scientists in Africa.
"The
Africa Fellowship is a programme that is aligned to the African Renaissance
vision. The success of South Africa's health science research is
closely linked to the success of Africa's scientists," he said.
