(PSYCHIATRIC TIMES) - Human immunodeficiency virus/acquired immunodeficiency syndrome is an important public health problem throughout the world, with sex being the predominant mode of transmission of HIV. Despite the fact that awareness of HIV and AIDS transmission is pervasive, risky sexual behavior has been increasing in many parts of the world in recent years, with a concomitant rise in new cases of HIV and other sexually transmitted diseases (STDs) (Centers for Disease Control and Prevention, 2003; Desquilbet et al., 2002; Rosenberg and Biggar, 1998; Wolitski et al., 2001). The World Heath Organization (WHO) and Joint United Nations Programme on HIV/AIDS (UNAIDS) (2000) has recommended that surveillance of the HIV/AIDS epidemic should focus on populations most at risk of becoming newly infected with HIV—populations with high levels of risk behavior, including young people, men who have sex with men, and racial and ethnic minority heterosexual men and women.
Studies have shown that populations living with HIV and/or at risk for acquiring HIV are at elevated risk for psychiatric conditions (Bing et al., 2001; Lipsitz et al., 1994; Lyketsos et al., 1994; Williams et al., 1991). Thus, it is important to investigate the association between high-risk sexual behavior and psychiatric symptoms as part of the public health response to the HIV pandemic. While the findings have been mixed, a number of studies have found an association between elevated sexual risk behavior and the prevalence of psychiatric disorders (Axis I and Axis II) and psychiatric symptomatology. In this article, we review some of the major findings in this field, discuss hypothesized causal pathways for the association between psychopathology and sexual risk behavior, and address the implications for health care settings.
Substance Use and Abuse
Psychoactive substance use and abuse have consistently been found to be associated with sexual risk behavior and the acquisition or transmission of STDs/HIV among men and women (Harvey and Spigner, 1995; Katz et al., 2000; Stall and Purcell, 2000; Wingood and DiClemente, 1998). Most of these studies assessed frequency and amount of use of alcohol and illicit substances and did not assess the presence or absence of substance use disorders. Substances that were most often cited as being related to sexual risk behavior include alcohol, marijuana, crack, cocaine, methamphetamines and other recreational drugs. Among adolescents, Boyer et al. (2000) found that alcohol and marijuana use were substantially more common among sexually experienced adolescents than the national average. It has been shown that cigarette, alcohol and marijuana use are significant predictors of risky sexual behavior (Cooper, 2002; Harvey and Spigner, 1995; Malow et al., 2001).
Mood and Psychiatric Distress
Numerous studies have reported an association between negative affective states and increased sexual risk behavior in both adolescents and adults. This association has been seen across a wide range of populations, including adult men and women (Kelly et al., 1993), men who have sex with men (Marks et al., 1998; Perdue et al., 2003), HIV-positive adults (Kelly et al., 1993; Parsons et al., 2003), minority women (Champion et al., 2002; Orr et al., 1994), opioid users (Camacho et al., 1996), young gay and bisexual men (Strathdee et al., 1998), and adolescents (Brooks et al., 2002). Most of these studies assessed severity of psychiatric distress (i.e., depression, anxiety, hostility) without diagnostic assessments of psychiatric disorders. However, a few studies have found an association between mood disorders and posttraumatic stress disorder and increased sexual risk behavior (Hutton et al., 2001; Ramrakha et al., 2000; Rogers et al., 2003).
Unfortunately, systematic comparisons have not yet been conducted regarding the associations of different types of mood disorders with sexual risk behaviors. According to the DSM-IV, one of the main features of a manic episode is often hypersexuality. However, unipolar depression is much more pervasive than bipolar disorder. Although many people with relatively severe unipolar disorders do have reduced libido, there are many other people with depression who have fluctuating levels of libido that may often be high enough to lead to risky sexual behavior. Furthermore, unipolar depression increases risk for suicidal and self-destructive behavior. People who are self-destructive are perhaps less likely to inhibit their sexual impulses, because if they do not care about life itself, they may reason that there is no reason to care whether they acquire an STD.
