Differences in self-reported health-related quality of life in heterosexual and sexual minority women surviving cancer: 2013 to 2018 national health interview survey.

Abstract

e19038 Background: Health related quality of life (HRQoL) is associated with excess morbidity and mortality after cancer diagnosis. While a growing body of research indicates that sexual minority women (lesbian and bisexual women; SMW) experience greater risk for cancer diagnoses and cancer-related mortality, there is a paucity of evidence describing HRQoL in this population. This is a critical omission as assessment of sexual orientation differences in HRQoL may inform clinical interventions to improve health and survival of SMW after cancer diagnosis. This study examined associations between sexual orientation and HRQoL domains among female cancer survivors. Methods: Data from the 2013-2018 National Health Interview Survey (NHIS) was pooled. HRQoL was defined using individual indices across physical health, mental health, social, and financial domains. The association between sexual orientation and individual indices of HRQoL was assessed using weighted multivariable logistic regression analyses. Results: The sample included 97909 heterosexual, 1424 lesbian, and 1235 bisexual women who reported a cancer diagnosis. Sexual minority women were more likely to be college graduates (p < 0.001) and employed (p < 0.001); however, they had higher rates of being uninsured (p = 0.01) than their heterosexual counterparts. Reproductive cancers—including breast, ovarian, cervical, and uterine—accounted for 51% of cancer diagnoses in heterosexual women and 57.2% in SMW (p = 0.06). Sexual minority and heterosexual women had more similarities than differences in individual indices of HRQoL; however, several pertinent differences were noted. Specifically, SMW had higher odds of moderate (OR 1.46 [1.01-2.13]) and severe psychological distress (OR 2.10 [1.17-3.77]); chronic health conditions, including COPD (OR 1.72 [1.06-2.80]) and heart disease (OR 1.93 [1.32-2.83]); financial concerns about retirement (OR 1.36 [1.01-1.83]); food insecurity (OR 2.13 [1.23-3.68]), and severe food insecurity (OR 2.44 [1.28-4.67]). Conclusions: Sexual minority women with cancer diagnoses report worse indices of HRQoL. Poorer HRQoL may influence excess morbidity and mortality evidenced in these populations; however, future longitudinal studies are needed to assess prospective risk. Given our results, implementing interventions in the cancer setting to identify sexual minority patients in need of physical and mental health and financial services may reduce disparities.
