Variation in diet quality across sexual orientation in a cohort of U.S. women.

PURPOSE: Extensive prior research has shown that sexual minority women are more likely to have a number of cancer risk factors, thereby putting them at higher risk for cancer than heterosexual women. However, there has been little research evaluating the association between sexual orientation and diet quality. METHOD: Data come from participants (aged 24-54 years) enrolled in Nurses' Health Study 3, an ongoing, U.S.-based cohort study (N = 15,941). We measured diet using recommendations from the Dietary Approach to Stop Hypertension (DASH) and American Health Association (AHA) 2020 Strategic Impact Goals. RESULTS: We found limited evidence of differences across diet quality by sexual orientation. When examining predicted DASH scores, mostly heterosexual [predicted mean score (95% confidence interval), 24.0 (23.8, 24.3)] and lesbian [24.3 (23.8, 24.9)] women had healthier predicted DASH scores than the reference group of completely heterosexual women with no same-sex partners [23.6 (23.5, 23.7)]. Even though certain sexual minority women had overall healthier predict DASH scores, their consumption of certain food groups-low-fat dairy and fruit-was lower than completely heterosexual women with no same-sex partners. When measuring AHA scores, most sexual minority groups (completely heterosexual women with same-sex partners, mostly heterosexual women, and lesbian women) had higher diet quality compared to the reference group of completely heterosexual women with no same-sex partners. CONCLUSION: Sexual minority women, particularly mostly heterosexual women and lesbian women, had healthier diet quality than completely heterosexual women with no same-sex partners. These data suggest that cancer risk factors (e.g., smoking, drinking, and inactivity) other than diet would drive higher cancer rates among sexual minority compared to heterosexual women. Nonetheless, it is critical for all women to improve their diet quality since diet quality was poor among participants of all sexual orientations.

Maternal Comfort with Lesbian, Gay, and Bisexual People and Their Children's Drinking, Smoking, and Disordered Weight Control Behaviors as Adults.

Purpose: We investigated associations between maternal comfort with lesbian, gay, and bisexual (LGB) people during the participant's adolescence and their health indicators in adulthood. Methods: Data came from a prospective cohort, Growing Up Today Study (N = 7476), limited to men and women who provided information during their adulthood about recent binge drinking, cigarette smoking, or disordered weight control behaviors (DWCB) and whose mothers provided information during the participant's adolescence about her comfort with LGB people. Results: Increased maternal comfort with LGB people was associated with increased engagement in health indicators for heterosexual but not sexual minority adults (binge drinking, cigarette smoking, and DWCB for women; binge drinking for men). No association existed between maternal comfort with LGB people and binge drinking or cigarette smoking for sexual minority women, and binge drinking for sexual minority men. This resulted in statistically smaller differences across sexual orientation in cigarette smoking for women when their mothers were highly comfortable with LGB people compared with those whose mothers were uncomfortable with LGB people. There were no differences in binge drinking (women and men) and DWCB (women only) across sexual orientation when mothers were highly comfortable with LGB people. Conclusion: Maternal comfort with LGB people is associated with certain sexual orientation-related disparities in health indicators through adulthood, due to increased engagement in health indicators by heterosexual adults. Exposure to sexual orientation stigma in adolescence, measured as maternal comfort with LGB people, possibly drives well-known differences in drinking, smoking, and DWCB during adulthood between heterosexual and sexual minority adults.

Indoor Ultraviolet Tanning Among U.S. Adolescents and Young Adults: Results From a Prospective Study of Early Onset and Persistence.

PURPOSE: The purpose of the study was to test whether those who initiate tanning during adolescence are more likely to continue tanning in young adulthood, potentially increasing their risk for melanoma. METHODS: The study included prospective data from the Growing Up Today Study, a cohort study started in 1996 (N = 5,882). RESULTS: Among men and women who ever indoor UV tanned, those who indoor UV tan by age 17 years consistently indoor tanned at least twice the prevalence as those who did not indoor UV tan by age 17 years. Indoor tanning prevalence at age 27 years was nearly 4 times as high (18.8% vs. 4.8%) among men who started indoor tanning by age 17 years than those who did not indoor tan by age 17 years. These differences persisted through age 27 years and are more pronounced in men (18.8% vs. 4.8%) than in women (30.5% vs. 13.0%). CONCLUSION: Adolescents who indoor UV tan by age 17 years are more likely to continue to indoor tan through young adulthood than those who begin indoor UV tanning at age 18 years or older. Our findings suggest that interventions to prevent indoor UV tanning among minors may substantially reduce years of exposure to this carcinogenic behavior in young adults.

Sexual Orientation Differences in Cervical Cancer Prevention among a Cohort of U.S. Women.

BACKGROUND: Although much has been published in recent years on differences in Papanicolaou (Pap) tests across sexual orientation, other aspects of cervical cancer prevention remain underexplored, such as human papillomavirus (HPV) vaccination, HPV co-tests, or abnormal Pap tests. METHODS: Data came from participants (aged 24-54 years) enrolled in an ongoing, longitudinal, U.S.-based cohort study, the Nurses' Health Study 3 (N = 12,175). Analyses were restricted to participants who met the current guidelines for care (e.g., ≥21 years of age for Pap tests). RESULTS: Mostly heterosexual women were more likely to initiate HPV vaccination than completely heterosexual women with no same-sex partners. All other comparisons across sexual orientation for HPV vaccination initiation and completion and the age of initiation were not statistically significant. Compared with completely heterosexual women with no same-sex partners, mostly heterosexual and lesbian women had lower odds of having a Pap test within the past 2 years. Completely heterosexual women with same-sex partners, mostly heterosexual women, and bisexual women had their first Pap test at an earlier age, had higher odds of having an HPV co-test, and had higher odds of having a positive HPV or abnormal Pap test compared with completely heterosexual women with no same-sex partners. In contrast, lesbian women had lower odds of having positive HPV or abnormal Pap results (odds ratio, 0.65; 95% confidence interval, 0.49-0.86) than completely heterosexual women with no same-sex partners. CONCLUSIONS: There are significant differences across sexual orientation groups in cervical cancer prevention for Pap test timing and positive HPV and abnormal Pap tests, but few differences in HPV vaccination initiation, completion, and age at initiation. Interventions should focus on increasing routine Pap testing among mostly heterosexual and lesbian women.

Sexual orientation inequalities during provider-patient interactions in provider encouragement of sexual and reproductive health care.

The human papillomavirus (HPV) vaccination, sexually transmitted infection (STI) tests, and Papanicolaou (Pap) testing rates vary by sexual orientation, which may be due in part to healthcare providers (HCP) recommending this care unevenly. Data (N = 17,675) came from the Growing Up Today Study (GUTS) (N = 8039) and Nurses' Health Study 3 (NHS3) (N = 9636). Among participants who met clinical guidelines to receive the care in question, we estimated the probability of an HCP encouraging participants to have the HPV vaccination, STI tests, or Pap test. Regardless of sexual orientation, participants whose HCP knew their sexual orientation were more likely to have been encouraged to get care compared to those whose HCP did not know the participant's sexual orientation. Sexual minority men and women were more likely to be encouraged to obtain HPV vaccination, STI tests, and Pap test than same-gender, completely heterosexuals with no same-sex partners, with some variation by gender and the care in question. Lesbian women were the sole sexual orientation subgroup that was less likely to be encouraged to receive care (HPV vaccination and Pap test) than their same gender, completely heterosexual counterparts with no same-sex partners (odds ratio [95% confidence interval]: 0.90 [0.80-1.00] and 0.94 [0.91-0.98], respectively). The differences across sexual orientation in HCPs' encouragement of care indicate a possible explanation for differences in utilization across sexual orientation. Across the US, HCPs under-encourage HPV vaccination, STI tests, and Pap test for all sexual orientation groups. Lesbian patients appear to be at high risk of under-encouragement for the Pap test.
