IMPORTANCE Previous studies identified disparities in health and health risk factors among lesbian, gay, and bisexual (LGB) adults, but prior investigations have been confined to samples not representative of the US adult population or have been limited in size or geographic scope. For the first time in its long history, the 2013 and 2014 National Health Interview Survey included a question on sexual orientation, providing health information on sexual minorities from one of the nation's leading health surveys. OBJECTIVE To compare health and health risk factors between LGB adults and heterosexual adults in the United States. DESIGN, SETTING, AND PARTICIPANTS Data from the nationally representative 2013 and 2014National Health Interview Survey were used to compare health outcomes among lesbian (n = 525), gay (n = 624), and bisexual (n = 515) adults who were 18 years or older and their heterosexual peers (n = 67 150) using logistic regression.MAIN OUTCOMES AND MEASURES Self-rated health, functional status, chronic conditions, psychological distress, alcohol consumption, and cigarette use. RESULTSThe study cohort comprised 68 814 participants. Their mean (SD) age was 46.8 (11.8) years, and 51.8% (38 063 of 68 814) were female. After controlling for sociodemographic characteristics, gay men were more likely to report severe psychological distress (odds ratio [OR], 2.82; 95% CI, 1.55-5.14), heavy drinking (OR, 1.97; 95% CI, 1.08-3.58), and moderate smoking (OR, 1.98; 95% CI, 1.39-2.81) than heterosexual men; bisexual men were more likely to report severe psychological distress (OR, 4.70; 95% CI, 1.77-12.52), heavy drinking (OR, 3.15; 95% CI, 1.22-8.16), and heavy smoking (OR, 2.10; 95% CI, 1.08-4.10) than heterosexual men; lesbian women were more likely to report moderate psychological distress (OR, 1.34; 95% CI, 1.02-1.76), poor or fair health (OR, 1.91; 95% CI, 1.24-2.95), multiple chronic conditions (OR, 1.58; 95% CI, 1.12-2.22), heavy drinking (OR, 2.63; 95% CI, 1.54-4.50), and heavy smoking (OR, 2.29; 95% CI, 1.36-3.88) than heterosexual women; and bisexual women were more likely to report multiple chronic conditions (OR, 2.07; 95% CI, 1.34-3.20), severe psychological distress (OR, 3.69; 95% CI, 2.19-6.22), heavy drinking (OR, 2.07; 95% CI, 1.20-3.59), and moderate smoking (OR, 1.60; 95% CI, 1.05-2.44) than heterosexual women. CONCLUSIONS AND RELEVANCEThis study supports prior research finding substantial health disparities for LGB adults in the United States, potentially due to the stressors that LGB people experience as a result of interpersonal and structural discrimination. In screening for health issues, clinicians should be sensitive to the needs of sexual minority patients.Question What does one of the nation's leading health surveys teach us about health outcomes and health risk factors in lesbian, gay, and bisexual (LGB) adults when it first measured sexual orientation?Findings In this nationally representative study of approximately 68 000 adults, LGB adults were more likely to report impaired physical ...

Transgender and GNC adults face barriers to health care that may be due to a variety of reasons, including discrimination in health care, health insurance policies, employment, and public policy or lack of awareness among health care providers on transgender-related health issues.
