Social Adversity during Childhood increases Schizophrenia Risk

A new study published in the American Journal of Psychiatry suggests that "social adversity" during childhood increases risk of later developing schizophrenia as an adult.
The study reports that:
There is conflicting evidence concerning the association of social childhood factors and subsequent psychosis. Previous studies have had inadequate designs. The aim of the present study was to describe a broad range of social factors during childhood and the risk of developing psychosis later in life in a national cohort.
The study included looking at all children born in Sweden in 1963–1983—2.1 million persons—in family households participating in the national census of 1970, 1980, 1985, or 1990.
Social adversity was measured by what the study designers called "Hazard ratios" that were estimated for five different indicators of socioeconomic position (living in rented apartments, low socioeconomic status, single-parent households, unemployment, and households receiving social welfare benefits) from hospital admissions for schizophrenia and other psychoses during 1987–2002.
The study found that the more social adversity "harzard ratios" that a person experienced, the more likely they were to develop schizophrenia later in life.
The researchers concluded that: "The results indicate that social adversity in childhood and fetal life is independently associated with the risk of developing schizophrenia and other psychoses later in life. The risks increased with an increasing number of exposures, suggesting a dose-response relationship."
