Childhood bereavement contributes to future psychosis risk By Eleanor McDermid.

After accounting for confounders, the chance for psychosis was increased by 84 percent for people who dropped a nuclear relative between birth and the age of 2.9 years, and by 47 percent and 32 percent for those who experienced a death at the ages of 3.0 to 6.9 years and 7.0 to 12.9 years, respectively. Secondly, the higher risk may reflect a larger duration of exposure to adverse social effects linked to the death of a close relative. The risk was more powerful for affective than nonaffective psychosis and, again, it rose further with earlier age at exposure, such that the risk for affective psychosis was elevated 3.33-fold among people who shed a nuclear relative to suicide between birth and age 2.9 years.Related StoriesStudy evaluates efficiency of antiretroviral treatment in HIV-infected childrenStudy: Safe areas may play critical role in community-based HIV prevention effortsNew study finds high prevalence of HIV among pregnant refugee women in OntarioRebecca Baggaley, from Imperial College London, and one of the authors of the paper, said: This model demonstrates that ongoing provision of prevention initiatives for stopping the pass on of HIV is vital.
