Risk raised by relatives

The number of family members with a specific anxiety disorder can predict the likelihood of a child developing the same disorder, according to a Brazilian study of 9937 children age 6–12 years.

When no family members had an anxiety disorder, prevalence in the child being studied was 10%, but the more family members with anxiety, the higher the risk to the child.

Risk increased to 30% when 1–20% of relatives were affected, and to 80% when at least 80% of family members were affected. 

The findings were presented on 25 March at the Anxiety Disorders Association of America 31st Annual Conference.
