Exposure to heavy air pollution during childhood linked to schizophrenia later: JAMA

Air pollution is a serious risk to human health that affects nearly everyone in the world and nearly every organ in the body. Fortunately, it is largely a preventable risk and by reducing pollution at its source can have a rapid and substantial impact on health. Air pollution for sure affects physical health, and research results now conclude that it also affects our psychological health.

Researchers have found that children who are exposed to a high level of air pollution while growing up, have an increased risk of developing schizophrenia. Children who grow up in areas with heavy air pollution have a higher risk of developing schizophrenia.The results of the study have been published in the scientific journal JAMA Network Open.

The lifetime risk of developing schizophrenia is approximately two per cent in the general population. For people exposed to the lowest level of air pollution, the lifetime risk is just under two per cent, while the lifetime risk for those exposed to the highest level of air pollution is approx. three per cent.

“The study shows that the higher the level of air pollution, the higher the risk of schizophrenia. For each 10 μg/m3 (concentration of air pollution per cubic metre) increase in the daily average, the risk of schizophrenia increases by approximately twenty per cent. Children who are exposed to an average daily level above 25 μg/m3 have an approx. sixty per cent greater risk of developing schizophrenia compared to those who are exposed to less than 10 μg/m3,” explains Senior Researcher Henriette Thisted Horsdal, who is behind the study.

The study included 23,355 people in total, and of these, 3,531 developed schizophrenia. Though the results demonstrate an increased risk of schizophrenia when the level of air pollution during childhood increases, the researchers cannot comment on the cause. Instead, they emphasize that further studies are needed before they can identify the cause of this association.

“The risk of developing schizophrenia is also higher if you have a higher genetic liability for the disease. Our data shows that these associations are independent of each other. The association between air pollution and schizophrenia cannot be explained by a higher genetic liability in people who grow up in areas with high levels of air pollution,” says Henriette Thisted Horsdal about the study, which is the first of its kind to combine air pollution and genetics in relation to the risk of developing schizophrenia.
