Although homosexuality is not considered a mental illness, various mentally ill individuals are more likely to engage in homosexual behavior than mentally normal individuals, as documented below. One wonders why?

Borderline personality disorder

Borderline personality disorder is a pervasive pattern of instability of interpersonal relationships, self-image, affects, and marked impulsivity that begins by early adulthood and is present in a variety of contexts such as gambling, spending money irresponsibly, binge eating, substance abuse, engaging in unsafe sex, driving recklessly, or displaying recurrent suicidal behavior, gestures, threats, or self-mutilating behavior (DSM-IV-TR). Several studies have reported a relative overrepresentation of homosexuals and bisexuals among individuals with borderline personality disorder:

  • Zubenko et al. described some samples of individuals with borderline personality disorder.1 In a sample of men, 57% of them were homosexual. In another sample of men, 21% were homosexual, 5% bisexual and 11% suffered from various paraphilias. In yet another sample, 53% of the men were homosexual and so were 11.5% of the women.
  • Stone mentioned that in a sample of individuals with BPD, 9.8% of the men and 1.4% of the women were exclusively homosexual;2 he did not report data about the proportion that manifested bisexual interests. The proportion of exclusively homosexual women in this sample is greater than the proportion of exclusively homosexual women in probability samples of the general population.
  • Dulit et al. reported that in a sample of individuals with BPD, the proportions of heterosexuals, homosexuals, and bisexuals among men were 44%, 22%, and 26%, respectively, whereas these proportions among women were 73%, 3%, and 11%, respectively (sexual orientation could not be determined in some individuals).3
  • In a sample of men, 16.7% of the men with BPD were homosexual vs. 1.7% of controls.4
  • Molina Ramos et al. have also documented an association of homosexuality with BPD.5

Mentally ill homeless individuals

Nonheterosexuals are relatively overrepresented among homeless female adolescents/women (with increased mental disorders).6, 7 and mentally ill mentally ill homeless men:

  • Susser et al. studied 122 mentally ill homeless men in a New York City shelter.8 Among 122 men, 65 (53%) were sexually active, 56 with women and 20 with men (11 who had sex with both women and men were counted in each group).
  • In another examination of 39 mentally ill homeless men, of which three-fourths had a schizophrenia-spectrum disorder, 26 reported any sexual activity during the previous 6 months; 23 reported sex with women, and 9 reported sex with men.9

Schizophrenia and general mental illness

Nonheterosexuals are relatively overrepresented among mentally ill patients, especially schizophrenics:

  • In sample of 170 consecutively seen mentally ill inpatients without BPD, only 78% of the men and 89% of the women were heterosexual.10
  • In an examination of 157 adolescent males (ages 14-17 years) in a mental hospital, of which 42 had psychopathy, 49 had mental retardation, and 66 had schizophrenia, 61% of the total manifested homosexual behavior or desire.11
  • In an examination of 145 mental patients in Melbourne, 55.2% had schizophrenia, 15.9% reported intravenous drug use, and 20% reported multiple sexual partners in the previous year.12 12.6% of the men reported homosexual behavior (9.2% reported anal sex), about half of the men reported sex with a prostitute, and 19% of the women reported sex with a bisexual man.
  • Cournos et al. studied 95 schizophrenics. 10% of the patients had engaged in homosexual activity in the preceding 6 months and 22% during their lifetime; the frequency was similar among men and women.13 The patients also reported heterosexual behavior.
  • Although less than 1% of the general population has schizophrenia, in a sample of 561 women (95% identifying as lesbian, others identifying as bisexuals or non-identifying) who were predominantly white, highly educated, urban, and between 25 and 50 years of age, 3% had been diagnosed with schizophrenia or psychosis;14 most psychoses are schizophrenias.

Schizophrenics manifest an increased likelihood of a variety of sexual delusions/hallucinations and unusual sexual behaviors, including homosexual behaviors.15, 16, 17, 18, 19, 20, 21

Eating disorders

Homosexual men are relatively overrepresented among male patients with eating disorders.22, 23, 24, 25 Male homosexuals are more likely to manifest eating disorder symptoms compared to heterosexual men even after controlling for depression, self-esteem and comfort with sexual orientation.26

Homosexual and heterosexual women likely have a similar prevalence of eating disorders.27 In a population-based study of adolescents (36,320 students in grades 7 through 12), more homosexual than heterosexual girls reported a positive body image (42.1% vs. 20.5%), but these two groups did not differ with respect to frequent dieting, binge eating, or purging behaviors.28
