Racial differences in hormone replacement therapy prescriptions

Global view of vasomotor symptoms and sleep disturbance in menopause: a systematic review

Studies have shown racial/ethnic differences in the prevalence of vasomotor symptoms (VMS), sleep disturbance and VMS treatment in menopause. To assess the reproducibility of these differences, we systematically reviewed observational studies, published in 2000-2021, reporting the prevalence/incidence of VMS, sleep disturbance or treatment use in menopausal women stratified by race/ethnicity. We screened 3799 records from PubMed and Embase and included 27 papers (19 studies). No incidence data were found. Prevalence data varied widely, but some common patterns emerged. In all five studies comparing VMS between Black women and White, Hispanic and/or East Asian women, the prevalence was highest in Black women and lowest in East Asian women. The prevalence of sleep disturbance overall was compared among Black, White and East Asian women in two study populations, and was highest in White women in both papers. Sleep disturbance was more common than VMS in East Asian women. In all four studies comparing hormone therapy use between White women and Black and/or East Asian women, treatment use was more common in White women. These results highlight the need for individualized counseling and treatment, outreach to under-served minorities, and standardized definitions and outcome measures for VMS and sleep disturbance for future studies.

Long-term effect of the Women's Health Initiative study on antiosteoporosis medication prescribing

AIM

To describe long-term prescribing patterns of osteoporosis therapy before and after the Women's Health Initiative (WHI) publication.

METHODS

We conducted a time-series analysis from 1997 to 2005 using nationally representative data based on office-based physician and hospital ambulatory clinic visits. Bivariate and multivariable analyses were conducted using chi-square tests and logistic regression, respectively, and trends in the prevalence of osteoporosis therapies were evaluated per 6-month (semiannual) intervals. Linear regression and graphic techniques were used to determine statistical differences in the prevalence trends between the two periods.

RESULTS

Overall prevalence of therapeutic or preventive osteoporosis therapy was similar between the WHI periods. However, a significant decrease in estrogen therapy and increases in bisphosphonates, calcium/vitamin D were observed in the period after the WHI publication (p < 0.05). Multiple logistic regression analysis showed older age and white race were associated with a higher likelihood of antiosteoporosis medication (AOM) prescription, and Medicaid insurance type was associated with a lower likelihood of an AOM prescription. Excluding calcium/vitamin D, nonestrogen therapy was more likely to be prescribed in the after-WHI period (office-based physician clinic: [adjusted OR, aOR] 2.49 [2.04-4.04]; hospital-based clinic: aOR 2.42 [1.67-7.50]) Nonestrogen therapy was more prevalent in visits made by older women, women of white race, women with contraindicated conditions for estrogen therapy, and women from the Northeast region.

CONCLUSIONS

After the WHI publication, the overall prevalence of osteoporosis therapy did not change; however, a shift from estrogen to nonestrogen therapy was observed after the WHI publication. Black women were less likely to receive nonestrogen antiosteoporosis therapy in hospital-based clinics.

Racial and ethnic disparities in benign gynecologic conditions and associated surgeries

Common gynecologic conditions and surgeries may vary significantly by race or ethnicity. Uterine fibroid tumors are more prevalent in black women, and black women may have larger, more numerous fibroid tumors that cause worse symptoms and greater myomectomy complications. Some, but not all, studies have found a higher prevalence of endometriosis among Asian women. Race and ethnicity are also associated with hysterectomy rate, route, and complications. Overall, the current literature has significant deficits in the identification of racial and ethnic disparities in the incidence of fibroid tumors, endometriosis, and hysterectomy. Further research is needed to better define racial and ethnic differences in these conditions and to examine the complex mechanisms that may result in associated health disparities.

Ovarian cancer risk factors in African-American and white women

Ovarian cancer is the most lethal gynecologic malignancy in both African-American and white women. Although prevalences of many ovarian cancer risk factors differ markedly between African Americans and whites, there has been little research on how the relative contributions of risk factors may vary between racial/ethnic groups. Using data from a North Carolina case-control study (1999-2008), the authors conducted unconditional logistic regression analyses to calculate odds ratios and 95% confidence intervals for ovarian cancer risk factors in African-American (143 cases, 189 controls) and white (943 cases, 868 controls) women and to test for interactions by race/ethnicity. They also calculated attributable fractions within each racial/ethnic group for the modifiable factors of pregnancy, oral contraceptive use, tubal ligation, and body mass index. Many risk factors showed similar relations across racial/ethnic groups, but tubal ligation and family history of breast or ovarian cancer showed stronger associations among African Americans. Younger age at menarche was associated with risk only in white women. Attributable fractions associated with tubal ligation, oral contraceptive use, and obesity were markedly higher for African Americans. The relative importance of ovarian cancer risk factors may differ for African-American women, but conclusions were limited by the small sample. There is a clear need for further research on etiologic factors for ovarian cancer in African-American women.

Factors associated with undergoing bilateral salpingo-oophorectomy at the time of hysterectomy for benign conditions

OBJECTIVE

To identify possible factors associated with undergoing bilateral salpingo-oophorectomy (BSO) at the time of hysterectomy among women with benign conditions.

METHODS

This was a cross-sectional analysis using the 2005 Nationwide Inpatient Sample. Women aged 18 years or older who underwent hysterectomy with BSO or hysterectomy only for a benign condition were included. We examined a broad range of factors associated with undergoing BSO in multivariable analyses.

RESULTS

Fifty-two percent of 461,321 hysterectomies included BSO, with a mean age of 49 years compared with 43 years in the hysterectomy-only group (P<.001). The odds of BSO were two times higher in the Midwest and South and 1.67 times higher in the West as compared with the Northeast (P<.001). Women who were uninsured or had Medicaid were more likely to undergo BSO compared with those with private insurance (odds ratio 1.86, 95% confidence interval 1.14-3.04 for "no charge/charity," odds ratio 1.21, 95% confidence interval 1.08-1.35 for Medicaid) Although BSO was more common among white women than African-American, Latina, and Asian women (P<.001), lower income was associated with BSO among African-American and white women only, not among Asian and Latina women (P=.007 for test for interaction). BSO was eight times as likely with a laparoscopic hysterectomy and 12 times as likely with an abdominal hysterectomy compared with a vaginal approach (P<.001). Women who had endometriosis, pelvic infection, or an ovarian cyst were more likely to undergo BSO (P<.001) compared with women who did not have these diagnoses.

CONCLUSION

There is significant nationwide variation in the practice of BSO. Age, route of hysterectomy, and diagnosis at surgery affect BSO rates. Nonclinical factors such as race or ethnicity, insurance status, income, and geographic location are also associated with BSO practice.

Racial and ethnic disparities in breast cancer: a multilevel perspective

Although the etiology of racial and ethnic disparities in breast cancer is complex, the studies reviewed here suggest many possible culprits. In the authors' model, outcomes at the cellular level reflect not only genetic constitution and the hormonal milieu but also the interactions of predictors at multiple levels. At the societal level, important predictors include toxin and hormone exposure, access to care, quality of care, and social support. At the individual level, reproductive history, exogenous hormone use, diet,exercise, and response to stress all may influence cellular outcomes. The smooth transition from normal cell function to apoptosis occurs when the interactions between factors at the societal, individual, and cellular levels are harmonious. Perturbations at the societal level, however, such as inferior quality of care, or at the individual level, such as exogenous hormone use,can have profound effects on cell biology and predispose to neoplasia. When these perturbations are systematic and vary by race or ethnicity, disparities in breast cancer incidence and mortality result. Increasing incidence of breast cancer among both men and women likely reflects important trends at the societal and individual levels. These trends may include increased toxin exposure, increased obesity, and changes in the timing and number of births. Efforts to reduce breast cancer incidence and disparities must consider societal and individual factors and the important effects these factors can have on normal cell function.

Clinical and personal relationships between oral contraceptive and hormone replacement therapy use among US women physicians

OBJECTIVE

To examine relationships between a history of oral contraceptive (OC) use and current use of or intention to use hormone replacement therapy (HRT).

DESIGN

The Women Physicians' Health Study examined a stratified random sample of US women MDs, aged 30 to 70 years (4,501 respondents; a 59% response rate).

RESULTS

Among postmenopausal physicians who previously used OCs, current HRT use was significantly associated ( < 0.05) with being younger, living somewhere besides the East Coast, being sexually active, being an obstetrician/gynecologist, having no history of breast cancer, having a longer use of OCs, and being posthysterectomy. Among premenopausal physicians, intended future HRT use was significantly associated with being white, being an obstetrician/gynecologist, being in good health, living somewhere besides the East Coast, being a longer user of OCs, and having more extensive, recent continuing medical education. Among women who had taken both OCs and HRT, there were no significantly elevated rates in any of the 15 health conditions we examined (after controlling for family history). Postmenopausal physicians who took HRT (and premenopausal OC-using physicians intending to take HRT) were significantly more likely to counsel their patients on HRT use. Among post-OC HRT-users, 44% counseled their postmenopausal female patients on HRT at least yearly versus 22% of post-OC HRT-nonusers (74% v 45% among such primary care physicians).

CONCLUSIONS

Physicians' personal OC/HRT use may strongly affect their patient counseling practices. HRT use after OC use was not associated with any obvious increases in examined diseases in this population.

Racial differences in physician recommendation of hormone replacement therapy

PURPOSE

Previous studies have suggested that black women may be less likely than white women to be offered and to take hormone replacement therapy (HRT). Thus, race and other factors associated with physician recommendation of HRT that may influence women's decisions about HRT were examined.

METHODS

Data were from a baseline assessment of participants in a randomized controlled trial designed to evaluate the efficacy of a tailored decision-aid on HRT decision-making. We telephone interviewed 581 Durham women ages 45-54. The association of race and other factors with reported physician recommendation of HRT was tested using chi(2) and logistic regression analysis.

RESULTS

Overall, 45% of women surveyed reported that their physician recommended HRT; black women were significantly less likely than white women to report being advised about HRT (35% vs. 48%, respectively, P < 0.005). Additional factors associated with being recommended HRT included older age, being postmenopausal, having had a hysterectomy, having thought about the benefits of HRT, and being satisfied with information about HRT.

CONCLUSIONS

Black women are less likely than white women to receive physician recommendation of HRT. Racial differences in patient-provider communication about HRT exist and thus require greater diligence on the part of health care providers to minimize such a gap.
