HIV-related factors not associated with increased risk of suicide among people with HIV in France

Approximately 4% of deaths among people with HIV in France are due to suicide, investigators report in HIV Medicine. Suicide incidence remained stable over 13 years of follow-up, but HIV-related factors were not associated with an increased risk of suicide.

“We found that most factors associated with suicide mortality among PLHIV [people living with HIV] were similar to those in the general population,” comment the authors. “Suicide prevention measures should target PLHIV with the psychological morbidities identified in our cohort.”

European studies have shown that the suicide rate fell among HIV-positive individuals after the introduction of effective antiretroviral therapy. Nevertheless, it still remains between three- and five-fold higher than that seen in the general population.

In France, suicide is the sixth most common cause of death among people with HIV, accounting for 5% of deaths in 2010, compared to 1.7% in the general French population.

But factors associated with increased suicide risk in HIV-positive people in the era of modern HIV therapy are poorly understood.

A team of French investigators designed a study comparing the characteristics of HIV-positive people who died from suicide between 2000 and 2013 with those of closely matched HIV-positive controls. Each suicide was matched with four controls. Patients received care at 19 hospitals across France.

Overall, suicide accounted for 4% of all recorded deaths among HIV-positive people. The incidence of suicide mortality was 45.9/100,000 person-years for the period 2000 to 2006 and 46.5/100,000 person-years between 2007 and 2013.

“Between 1990 and 2010, a decrease of > 20% in suicide mortality in the general population was observed in France and some other European countries. In the multicohort European DAD study among PLHIV, rates of suicide fell by around half between the early cART era (1999-2000) and the 2007-2008 period,” note the authors. “In contrast, since 2000, the rate of suicide among PLHIV in France has remained stable, accounting for 4%, 5% and 5% of causes of death in 2000, 2005 and 2010, respectively.”

The investigators suggest that the continuing high rate of death from suicide seen among people with HIV can be explained by the high prevalence of mental health problems among these individuals.

The study included 70 people who died from suicide and 279 controls.

Patients who died from suicide had a mean age of 45 years and 80% were men. Most (91%) were born in France and 73% lived alone. A quarter had children. The majority (83%) were taking antiretrovirals. The mean CD4 cell count was 487 cells/mm3 and just under two-thirds had an undetectable viral load. Active or substitute drug use was noted in 25% of cases and 76% had a history of a psychiatric disorder.

After controlling for potential confounders, several risk factors were associated with an increased risk of death from suicide, including living alone (p = 0.02), not having children (p = 0.008), active or substituted drug use (p = 0.03), alcohol abuse (p = 0.007), history of depression (p = 0.007), a past suicide attempt (p = 0.008) and treatment with psychotropic drugs (p < 0.0001).

No HIV-related factor was associated with death from suicide.

“Identifying risk factors associated with dying by suicide in PLHIV is necessary to improve quality of care and may help to identify patients who could benefit the most from interventions aimed at preventing suicide,” conclude the authors. “In the cART era, HIV-related factors are no longer associated with a higher risk of suicide mortality.”

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
