In the second section, health maintenance and prevention strategies are reviewed. Health concerns, including sexually transmitted diseases, reproductive issues, and substance abuse, are reviewed. The chapter on mental health concerns is particularly helpful and relevant. Although not all of the studies reviewed involve ideal probability samples, Ryan and Futterman cite a recent population-based study finding that suicide attempts are up to four times more likely in lesbian and gay youth than in their heterosexual peers. This risk can be reduced by providing realistic information and increasing social support. Another chapter on mental health assessment treatment outlines psychiatric history taking with lesbian and gay youth, suicide assessment, and indications for psychiatric referral. The authors also point out research findings that reparative therapy—psychotherapy aimed at changing sexual orientation to heterosexual—may contribute to mental health problems and suicide risk (1).
