Mental illness: Women are more likely to be diagnosed with anxiety or depression, while men tend toward substance abuse or antisocial disorders

A study looked at the prevalence by gender of different types of common mental illnesses. The researchers also found that women with anxiety disorders are more likely to internalize emotions, which typically results in withdrawal, loneliness and depression. Men, on the other hand, are more likely to externalize emotions, which leads to aggressive, impulsive, coercive and non-compliant behavior, according to the study. Researchers analyzed data collected in 2001 and 2002 by a National Institutes of Health survey of 43,093 U.S. residents 18 and older who were civilians and not institutionalized. Of those, 57% were women and 56.9% were white; 19.3% were Hispanic or Latino; 19.1% were African-American; 3.1% Asian, native Hawaiian or Pacific Islander; and 1.6% were American Indian or native Alaskan.
