Children born to a mother or father with schizophrenia are twice as likely to die within the first year of life, new research shows.

The study, published in the October issue of the British Journal of Psychiatry, examined 2 million births in Sweden that took place between 1983 and 2002, using data from a number of population-based registers.

Previous studies have shown that women with schizophrenia have an increased risk of negative pregnancy outcomes. However, little is known about the risks involved if the father has schizophrenia.

The study found that babies with a mother or father with schizophrenia faced a doubled risk of infant mortality. The researchers do not think there are genetic explanations for this increased risk. This was because the study also examined the risk of infant death if the parent had a sibling or a half-sibling with schizophrenia. A genetic factor would be indicated if the risk was significantly higher for full siblings compared with half siblings, but the risk was found not to be increased.

The study also found that both mothers and fathers with schizophrenia were found to have an increased risk of having a baby with a low-birth weight, preterm delivery and small-for-gestational-age births.

These increased risks were largely explained by the fact that children of parents with schizophrenia are often born into more adverse social environments. For example, women with schizophrenia are more likely to smoke, and are less likely to cohabit with their child's father. Both women and men with schizophrenia are also likely to be more socially disadvantaged and have a lower level of education.

Based on the findings of this study, the researchers from the Karolinska Institutet in Stockholm believe that staff working in maternity and child care units need to be more aware of the risks involved following a pregnancy to parents with schizophrenia.

The Royal College of Psychiatrists is the professional and educational body for psychiatrists in the United Kingdom and the Republic of Ireland. We promote mental health by:

- Setting standards and promoting excellence in mental health care
- Improving understanding through research and education
- Leading, representing, training and supporting psychiatrists
- Working with patients, carers and their organisations

As well as running its membership examination (MRCPsych), and visiting and approving hospitals for training purposes, the College organises scientific and clinical conferences and lectures and continuing professional development activities. The College publishes books, reports and educational material for professionals and the general public. It also publishes the British Journal of Psychiatry, Psychiatric Bulletin, Advances in Psychiatric Treatment and International Psychiatry, all of which are now available on-line.

The Royal College of Psychiatrists has been in existence in some form since 1841. First as the "Association of Medical Officers of Asylums and Hospitals for the Insane" (later changed to the Medico Psychological Association) then, in 1926 receiving its Royal Charter to become the "Royal Medico Psychological Association, and finally, in 1971 receiving a Supplemental Charter to become the "Royal College of Psychiatrists" we know today.
