Sexual minority adolescents face mental health disparities relative to heterosexual adolescents. We evaluated temporal changes in US adolescent reported sexual orientation and suicide attempts by sexual orientation.
We used Youth Risk Behavioral Surveillance data from 6 states that collected data on sexual orientation identity and 4 states that collected data on sex of sexual contacts continuously between 2009 and 2017. We estimated odds ratios using logistic regression models to evaluate changes in reported sexual orientation identity, sex of consensual sexual contacts, and suicide attempts over time and calculated marginal effects (MEs).
The proportion of adolescents reporting minority sexual orientation identity nearly doubled, from 7.3% in 2009 to 14.3% in 2017 (ME: 0.8 percentage points [pp] per year; 95% confidence interval [CI]: 0.6 to 0.9 pp). The proportion of adolescents reporting any same-sex sexual contact increased by 70%, from 7.7% in 2009 to 13.1% in 2017 (ME: 0.6 pp per year; 95% CI: 0.4 to 0.8 pp). Although suicide attempts declined among students identifying as sexual minorities (ME: −0.8 pp per year; 95% CI: −1.4 to −0.2 pp), these students remained >3 times more likely to attempt suicide relative to heterosexual students in 2017. Sexual minority adolescents accounted for an increasing proportion of all adolescent suicide attempts.
The proportion of adolescents reporting sexual minority identity and same-sex sexual contacts increased between 2009 and 2017. Disparities in suicide attempts persist. Developing and implementing approaches to reducing sexual minority youth suicide is critically important.
The proportion of the population that identifies as sexual minorities may be increasing over time. How sexual orientation and related health disparities are changing over time in the United States remains unstudied in a consistent sample over time.
Between 2009 and 2017, the proportion of US adolescents identifying as sexual minorities increased 96%, from 7.3% to 14.3%. The proportion of adolescents reporting same-sex sexual contacts increased 70%, from 7.7% to 13.1%. Sexual minority disparities in suicide attempts persisted.
Adolescence is a time of sexual and social development and increased risk for mental health disorders, suicide, substance abuse, and sexually transmitted disease transmission.1 Adolescents who are sexual minorities, defined as having same-sex attraction, behavior, or orientation, face elevated levels of each of these health risks, particularly suicide.2–4 Those identifying as sexual minorities have nearly 5 times the rate of suicide attempts relative to their heterosexual peers on the basis of representative data from the Youth Risk Behavioral Surveillance Survey (YRBSS).2 The disproportionate burden of poor mental health among sexual minorities has been linked to stigma.5,6
Adolescents are developing in a changing societal context for sexual minorities. Public support for same-sex marriage has increased over time, from 37% in 2009 to 62% in 2017.7 Same-sex marriage, linked to improved mental health,8,9 has been legal across the United States since 2015.10 At the same time, recent years have seen a rise in state and national policies curtailing sexual minority rights and linked to worse mental health.11,12 Changes in the social context may affect sexual orientation identity and reporting.
Each of the 3 dimensions of sexual orientation—attraction, identity, and the sex of sexual partners—may differ from each another, may change over time among individuals and in populations, and may be influenced by the broader social context.13–15 There is evidence of broad underreporting of same-sex attraction, sexual minority identity, and same-sex sexual behavior, even on anonymous surveys.16 In a study of adult women in the United States, legal recognition of same-sex relationships was associated with women reporting that their sexual orientation identity changed from heterosexual to a minority sexual orientation over time.17
Little previous research has evaluated how reported sexual orientation and related health disparities have changed over time. Based on representative data from adults in Britain, reports of lifetime same-sex sexual contact increased from 4% to 16% among women and from 6% to 7% among men between a 1990 and 1991 survey wave and a 2010–2012 survey wave, a period when support for same-sex relationships increased.18 Although few surveys representative of the US population have included questions on sexual orientation until recent years, some YRBSS states have included sexual orientation questions for several years. A previous analysis of changes in sexual orientation over time based on YRBSS data found increases in the proportion of adolescents reporting sexual minority identities and same-sex sexual contact between 2005 and 2015,19 but the study was based on potentially overlapping data from states and cities in different combinations across years (7 sites in 2005, increasing to 42 sites by 2015), making it difficult to determine if changes over time were due to the sites included in each year or changes in sexual orientation.20 The study also did not include evaluation of changes in mental health disparities over time.
Understanding temporal changes in the proportion of adolescents who are sexual minorities and changes in suicidality among those who are sexual minorities is important to guide policies and programs that reduce health disparities, particularly at a time of increasing adolescent suicide fatalities.21 We estimated population-level changes in adolescent sexual orientation identity, same-sex sexual contacts, and suicide attempts on the basis of YRBSS data from states that continuously collected representative data between 2009 and 2017.
Methods
Sample
We used data from high school students from the state-level YRBSS.22 The YRBSS is a repeated cross-sectional survey conducted in every odd year through partnerships between the Centers for Disease Control and Prevention (CDC) and state health or education departments. The YRBSS uses 2-stage sampling and population weighting to develop a sample representative of students in each state. States decide which questions to include in the YRBSS. Whereas <10 states collected sexual orientation data in 2009, 32 states did so in 2017.
We defined 3 samples. Sample A consisted of YRBSS data from adolescents from the 6 states that collected information on sexual orientation identity in each survey year between 2009 and 2017 and that maintained a consistent sampling frame during that time period: Delaware, Illinois, Massachusetts, Maine, North Dakota, and Rhode Island. Sample B consisted of YRBSS data from adolescents from a different set of the 4 states that collected information on the sex of sexual contacts in each survey year between 2009 and 2017, that maintained a consistent sampling frame during that time period, and that also collected data on whether adolescents had ever been forced to have sexual contact: Connecticut, Delaware, Illinois, and Rhode Island. We excluded sample B participants without any sexual contact as well as those who reported being forced to have sexual contact; it was not possible to determine the extent to which such contact was consensual. Sample C consisted of YRBSS data from adolescents in a subset of all 3 states that collected data on sexual orientation identity, the sex of sexual contacts, and sexual assault and that maintained a consistent sampling frame each year between 2009 and 2017: Delaware, Illinois, and Rhode Island. In sample C, we again excluded adolescents with no sexual contacts and who reported sexual assault. We could not investigate questions about gender identity because too few states included questions on gender identity. This study was exempt from institutional review board approval because it involved only the use of anonymous, secondary data.
Exposures
The main exposure of interest was time in years, measured as a linear term between 2009 and 2017.
Outcomes
There were 3 main outcomes of interest. The first outcome was reported sexual orientation identity, defined as any response other than “heterosexual” to the question, “Which of the following best describes you?” with 4 response categories: heterosexual, gay or lesbian, bisexual, or not sure. The second outcome was same-sex sexual contacts based on the respondent’s sex and the question, “During your life, with whom have you had sexual contact?” and response options of female, male, or female and males. The third outcome was ≥1 suicide attempt based on the question, “During the past 12 months, how many times did you actually attempt suicide?” We chose this binary outcome as the standard CDC approach to reporting suicide23 and because of particularly large disparities in suicide attempts by sexual orientation.2
Analyses
We conducted 4 main analyses, estimating odds ratios by conducting logistic regression analyses and calculating the marginal effects (MEs) at the mean value of covariates. We adjusted for race and ethnicity, sex, age in years, and state of residence in all analyses. We included weights calculated by the CDC to make the YRBSS population representative of all students in each state. We used linearized SEs, which are robust to heteroskedasticity.
We first estimated whether there were changes in reported sexual orientation identity over time using the 6-state sample A. We conducted the analyses among all adolescents and by sex. Second, we evaluated changes in reported same-sex sexual contacts over time using data from adolescents in the 4 sample B states among all adolescents and by sex. Third, we evaluated changes in reported sexual orientation identity among all sample C adolescents, by sex of sexual contact and by sex. Finally, we evaluated temporal changes in suicide attempts over time by sexual orientation (sample A) and by the sex of sexual contacts (sample B) overall and by sex through logistic regression analyses. Finally, we tabulated the proportion of all students who were both sexual minorities and reported suicide attempts and the proportion of suicide attempts that were among sexual minorities. We conducted all analyses in Stata version 12 (Stat Corp, College Station, TX).
Results
We describe the 3 samples in Table 1. Sample A consisted of 110 243 adolescents from 6 states that collected data on sexual orientation identity between 2009 and 2017. Sample B consisted of 25 994 adolescents from 4 states that collected data on the sex of sexual contacts and on sexual assault between 2009 and 2017. Sample C consisted of 20 655 sexually active adolescents from 3 states that collected data on sexual orientation identity, the sex of sexual contacts, and sexual assault between 2009 and 2017. Across the samples, the proportion of adolescents who were non-Hispanic white ranged from 56% to 63%, the proportion of adolescents who were non-Hispanic African American ranged from 13% to 19%, and the proportion of adolescents who were Hispanic ranged from 17% to 19%.

Among all adolescents in the 6 states that collected data on sexual orientation identity (sample A), the proportion of adolescents identifying as heterosexual declined from 92.7% in 2009 to 85.7% in 2017; the proportion of adolescents who identified as sexual minorities increased 96%, from 7.3% in 2009 to 14.3% in 2017 ( ME: 0.79 percentage points [pp] per year; 95% confidence interval [CI]: 0.65 to 0.94 pp; Fig 1A, Tables 2 and 3). The proportion who reported identifying as gay or lesbian doubled from 1.4% in 2009 to 2.8% in 2017 (ME: 0.13 pp per year; 95% CI: 0.07 to 0.20 pp). The proportion who reported identifying as bisexual increased 85%, from 3.9% in 2009 to 7.2% in 2017 (ME: 0.37 pp per year; 95% CI: 0.28 to 0.45 pp). The proportion who reported they were not sure of their sexual orientation identity increased 115%, from 2.0% in 2009 to 4.3% in 2017 (adjusted odds ratio [aOR]: 0.24 pp per year; 95% CI: 0.19 to 0.31 pp). The overall trends in sexual orientation identity were mirrored in trends for both male and female adolescents. Female adolescents were approximately twice as likely as male adolescents to identify as sexual minorities in 2017 (19.6% vs 8.9%).

In the population of adolescents from 4 states with data on the sex of consensual sexual contacts (sample B), there was a decline in the proportion of adolescents who reported only opposite-sex sexual contact from 92.3% in 2009 to 86.9% in 2017; the proportion of adolescents who reported any same-sex sexual contact increased 70%, from 7.7% in 2009 to 13.1% in 2017 (ME: 0.60 pp per year; 95% CI: 0.39 to 0.80 pp; Fig 1B, Tables 4 and 5). This increase reflects both an increase in the proportion of adolescents reporting only same-sex sexual contact (2.5% in 2009 to 5.2% in 2017; ME: 0.32 pp per year; 95% CI: 0.22 to 0.42) and an increase in the proportion of adolescents reporting sexual contact with both sexes (5.2% in 2009 to 7.9% in 2017; ME: 0.26 pp per year; 95% CI: 0.12 to 0.40 pp). These trends were consistent among male and female adolescents, although the increase in the proportion of male adolescents who had sexual contact with both sexes was not significant.

In the subset of adolescents with data on sexual orientation identity and sexual contact (sample C), those who had same-sex sexual contacts had 48.3 (95% CI: 38.6 to 60.6) times the odds of reporting sexual minority orientation identity relative to peers with only opposite-sex sexual contacts. Among those with same-sex sexual contacts, the proportion of adolescents reporting they were heterosexual declined from 41.9% in 2009 to 26.4% in 2017 (ME: −2.42 pp per year; 95% CI: −3.88 to −0.97; Fig 1C, Tables 6 and 7). There were no changes in the proportion reporting they were gay or lesbian (11.5% in 2009 and 13.8% in 2017; ME: 0.45 pp per year; 95% CI: −0.53 to 1.44 pp) or not sure of their sexual orientation (12.5% in 2009 and 16.0% in 2017; ME: 0.02 pp per year; 95% CI: −1.14 to 1.19 pp). There were increases in the proportion of adolescents who reported identifying as bisexual from 34.1% in 2009 to 43.7% in 2017, a 28% relative increase (ME: 2.01 pp per year; 95% CI: 0.73 to 3.30 pp).

Among sample C adolescents with only opposite-sex sexual contact, there was a smaller decline in the proportion of adolescents who reported identifying as heterosexual from 97.9% in 2009 to 95.2% in 2017 (ME: −0.28 pp per year; 95% CI: −0.42 to −0.14 pp; Fig 1D, Table 7). The proportion of adolescents reporting only opposite-sex sexual contacts who reported identifying as gay or lesbian increased from 0.1% in 2009 to 0.7% in 2017 (ME: 0.03 pp per year; 95% CI: <0.01 to 0.07). The proportion of adolescents reporting they were bisexual increased from 1.5% in 2009 to 2.5% in 2017 (ME: 0.13 pp per year; 95% CI: 0.04 to 0.22 pp), and the proportion reporting they were not sure of their sexual orientation identity increased from 0.5% in 2009 to 1.5% in 2017 (ME: 0.09 pp per year; 95% CI: 0.01 to 0.16 pp).
In 2017, suicide attempts remained elevated for sexual minority relative to heterosexual students on the basis of both orientation identity (ME: 12.6 pp; 95% CI: 10.0 to 15.1 pp; Fig 2A, Table 8) and the sex of sexual contacts (ME: 9.1 pp; 95% CI: 7.2 to 11.1 pp). Over time, there was a decline in suicide attempts among students with sexual minority identities (ME: −0.8 pp per year; 95% CI: −1.4 to −0.2), whereas suicide attempts among heterosexual students did not change (ME: −0.04 pp per year; 95% CI: −0.2 to 0.1 pp). There were also no changes in suicide attempts over time among students with same-sex sexual contacts (s (ME: 0.7 pp per year; 95% CI: −0.2 to 1.7 pp; Fig 2B, Table 9) or opposite-sex sexual contacts (ME: 0.09 pp per year; 95% CI: −0.2 to 0.3 pp). The same patterns were observed for each sex, although the declines in suicide attempts were not significant in the sex-specific analyses among students with sexual minority identities.

Sample B: sexually active adolescents from 4 states with data on sex of sexual contacts and sexual assault, 2009–2017. The pp are based on the MEs of sexual minority identity or any same-sex sexual contacts relative to heterosexual orientation identity or opposite-sex-only sexual contacts. Estimates are adjusted for the age, race and/or ethnicity, and sex categories described in Table 1.
P < .01.
Sexual minority adolescents accounted for an increasing proportion of suicide attempts (Supplemental Tables 10 and 11). Among adolescents who attempted suicide, the proportion who were of sexual minority orientation increased from 24.6% (95% CI: 20.1% to 29.2%) in 2009 to 35.6% (95% CI: 31.31% to 39.93%) in 2017. Among sexually active adolescents who attempted suicide, the proportion who had same-sex sexual contacts increased from 15.8% (95% CI: 9.3% to 22.4%) in 2009 to 30.3% (95% CI: 24.0% to 36.7%) in 2017.
Discussion
In a large, multistate sample of high school students in states that continuously collected sexual orientation data in the YRBSS, the proportion of adolescents who reported identifying as gay or lesbian, bisexual, or not sure of their sexual identity increased 96% between 2009 and 2017. The proportion of sexually active adolescents who reported consensual same-sex sexual contact also increased by 70% between 2009 and 2017. Increases in reported sexual minority orientation and same-sex sexual contacts could reflect either increased comfort with reporting or underlying population changes in sexual orientation. The observed increases in the proportion of the population reporting being sexual minorities are consistent with evidence from US adolescents19 and from British adults.18
Although suicide attempts declined over time among students identifying as sexual minorities, suicide attempts remained elevated among sexual minorities compared with heterosexual students. In 2017, students identifying as sexual minorities were >3 times as likely to attempt suicide relative to heterosexual students. Students with same-sex sexual contacts were more than twice as likely to report suicide attempts relative to those with only opposite-sex sexual contacts. With sexual minorities accounting for a growing proportion of the population and suicide attempt disparities persisting, sexual minority adolescents accounted for a growing proportion of all adolescent suicide attempts. Policies and interventions that address suicide attempts among sexual minority adolescents are critical, particularly given that suicide is the second leading cause of death among adolescents24 and is increasing over time.21
Policies and institutions play important roles in shaping mental health disparities.5,6 With increasing numbers of national and state policies restricting sexual minority rights and linked to worse mental health,11,25,26 sexual minority mental health disparities may grow. At the same time, policies around nondiscrimination, antibullying, and inclusive education policies may support sexual minority health.27
Health and educational institutions can also play an important role in reducing mental health disparities. Whereas most health care providers currently have little or no training in caring for sexual minority populations,28 medical and nursing schools can ensure that they train health care providers to provide culturally competent care that addresses sexual minority mental and sexual health disparities.29 School environments that are supportive of sexual minorities are also associated with improved sexual minority adolescent mental health.30,31
A strength of the study is that we used data representative of adolescents in each state. Whereas authors of a previous study on sexual orientation over time also used YRBSS data,19 our approach of only including states that collected sexual orientation data continuously throughout the study period allowed us to evaluate changes in sexual orientation in the same population over time. At the same time, the number of included states was small and represented only the northeast, mid-Atlantic, and Midwest, meaning the results may only be generalizable to these regions. We did not have data from states in the southeast, southwest, or northwest, and results are not representative of the entire country. The limited amount of data on sexual orientation available for this study highlights the importance of collecting sexual orientation data in the YRBSS and other population surveys. We also excluded adolescents who reported any sexual assault from the analyses involving sex of sexual contacts because we were unable to determine if sexual contacts were consensual. The YRBSS excludes youth absent from school; given evidence of the associations between sexual orientation and sexual assault2 and homelessness32 and between sexual assault and homelessness with suicide,33,34 this analysis may underestimate disparities in suicide attempts by sexual orientation. The YRBSS does not include questions on the attraction dimension of sexual orientation or on gender identity. We were unable to determine to what extent increases in sexual orientation identity and sex of sexual contact reflect changes in underlying identity and behaviors or changes in reporting.
Conclusions
The proportion of adolescents identifying as sexual minorities increased 96% and the proportion with consensual same-sex sexual partners increased 70% between 2009 and 2017. Disparities in suicide attempts by sexual orientation persisted in 2017. Sexual minority adolescents account for a growing proportion of adolescent suicide attempts. There is a need for further research on national, state, and local policies that reduce sexual minority adolescent suicide attempts and promote sexual minority health. There is also a need for further research on policies, training practices, and interventions to promote sexual minority health in education and health care institutions.
