Healthy Weight in Lesbian and Bisexual Women Aged 40 and Older: An Effective Intervention in 10 Cities Using Tailored Approaches

A Scoping Review of Physical Activity Interventions Among Sexual Minority Adults: A Call to Action for Future Research

Physical activity (PA) has a variety of well-established benefits for physical and mental health. However, there are PA disparities based on numerous sociodemographic characteristics, including sexual orientation. Mapping of PA interventions tailored to sexual minorities (ie, nonheterosexual) is currently absent from the literature.

PURPOSE

The purpose of this scoping review was to summarize the existing interventions focused on promoting PA among sexual minority (SM) adults.

METHODS

A search strategy was developed in consultation with a research librarian for PubMed, Web of Science, SportDiscus, and CINAHL. The scoping review was conducted using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines. Randomized and nonrandomized interventions that focused on increasing PA among SM adults were included. Data on study design, sample demographics, purpose of research, methodology, intervention components, theory-based constructs used, PA measures, and outcomes of the intervention were extracted.

RESULTS

Our search yielded 7289 articles, with 26 articles requiring full-text review. Four interventions were identified that focused on increasing PA among SM adults, with 2 focusing on lesbian/bisexual women, 1 focusing on lesbian/gay cancer survivors, and 1 focusing on men who have sex with men. Two of the 4 studies were successful at increasing PA, with varying psychosocial theories (ie, social cognitive theory and theory of reasoned action) and intervention strategies (ie, PA counseling, group meetings, and pedometers).

CONCLUSION

Findings of this review demonstrate a clear lack of PA interventions targeting SM adults, limiting the available knowledge required for preventionists, practitioners, and health care professionals to effectively promote PA through behavioral modification among this group.

Review of current 2SLGBTQIA+ inequities in the Canadian health care system

Gender identity and sexual orientation are determinants of health that can contribute to health inequities. In the 2SLGBTQIA+ community, belonging to a sexual and/or gender minority group leads to a higher risk of negative health outcomes such as depression, anxiety, and cancer, as well as maladaptive behaviors leading to poorer health outcomes such as substance abuse and risky sexual behavior. Empirical evidence suggests that inequities in terms of accessibility to health care, quality of care, inclusivity, and satisfaction of care, are pervasive and entrenched in the health care system. A better understanding of the current Canadian health care context for individuals of the 2SLGBTQIA+ community is imperative to inform public policy and develop sensitive public health interventions to make meaningful headway in reducing inequity. Our search strategy was Canadian-centric and aimed at highlighting the current state of 2SLGBTQIA+ health inequities in Canada. Discrimination, patient care and access to care, education and training of health care professionals, and crucial changes at the systemic and infrastructure levels have been identified as main themes in the literature. Furthermore, we describe health care-related disparities in the 2SLGBTQIA+ community, and present available resources and guidelines that can guide healthcare providers in narrowing the gap in inequities. Herein, the lack of training for both clinical and non-clinical staff has been identified as the most critical issue influencing health care systems. Researchers, educators, and practitioners should invest in health care professional training and future research should evaluate the effectiveness of interventions on staff attitudinal changes toward the 2SLGBTQIA+ community and the impact on patient outcomes.

Sexual Identity, Adverse Life Experiences, and Cardiovascular Health in Women

BACKGROUND

Adverse life experiences (ALE; eg, discrimination and sexual abuse) may contribute to cardiovascular disease (CVD) risk in sexual minority women (SMW), but few studies have tested whether ALE explain the association of sexual identity with cardiovascular health (CVH) markers in women.

OBJECTIVE

The aim of this study was to examine sexual identity differences in CVH among women and the role of ALE.

METHODS

In the Epidemiologic Study of Risk in Women, we used multinomial logistic regression to assess sexual identity differences (SMW vs heterosexual women [reference group]) in CVH markers (ideal vs poor, intermediate vs poor) using the American Heart Association's Life's Simple 7 metric and the total score. Next, we tested whether the association of sexual identity with the total CVH score was attenuated by traditional CVD risk factors or ALE.

RESULTS

The sample consisted of 867 women (395 heterosexual, 472 SMW). Sexual minority women were more likely to have experienced discrimination (P < .001) and lifetime sexual abuse (P < .001) than heterosexual women. Sexual minority women were also less likely to meet ideal CVH criteria for current tobacco use (adjusted odds ratio, 0.43; 95% confidence interval, 0.24-0.73) or intermediate CVH criteria for body mass index (adjusted odds ratio, 0.60; 95% confidence interval, 0.40-0.92). Sexual minority women had a lower cumulative CVH score (B [SE] = -0.35 [0.14], P < .01) than heterosexual women. This difference was not explained by traditional CVD risk factors or ALE.

CONCLUSIONS

Smoking, body mass index, and fasting glucose accounted for much of the CVH disparity due to sexual identity, but those differences were not explained by ALE. Health behavior interventions tailored to SMW should be considered.

Chronic Physiologic Effects of Stress Among Lesbian, Gay, and Bisexual Adults: Results From the National Health and Nutrition Examination Survey

OBJECTIVE

Social disadvantage is associated with markers of physiological dysregulation, which is linked to disease trajectories. Chronic experiences with discrimination are thought to result in the accumulation of physiological "wear and tear" known as allostatic load (AL) among socially marginalized populations such as sexual minorities. Using a nationally representative US sample, we examined whether (1) people who self-identified as homosexual or bisexual display higher levels of AL than heterosexual individuals and (2) subgroups of sexual identity would further differ from each other as a consequence of distinct experiences of marginalization.

METHODS

We use data from the 2001-2010 National Health and Nutrition Examination Survey. Employing multivariate regression methods with sex-specific analyses, we examined AL score differences among lesbian/gay (n = 211), bisexual (n = 307), homosexually experienced (n = 424), and exclusively heterosexual (n = 12,969) individuals, adjusting for possible confounding due to demographics, health indicators, and, among men, HIV infection status.

RESULTS

Results indicate that elevated AL was more common in bisexual men compared with exclusively heterosexual men (adjusted β = 0.25, 95% confidence interval [CI] = 0.05 to 0.44), with significantly higher levels of glycosylated hemoglobin A1c (adjusted odd ratio = 3.51, 95% CI = 1.46-7.92) and systolic blood pressure (adjusted odd ratio = 2.07, 95% CI = 1.02 to 4.18). Gay-identified men evidenced significantly lower AL (adjusted β = -0.22, 95% CI = -0.41 to -0.04). No significant differences in AL were observed among women.

CONCLUSIONS

These findings indicate that physiological dysregulation is more common in bisexual males compared with all other men. The results are discussed with regard to differences in health outcomes between individuals with different sexual orientations.

Development of an LGB-specific health literacy scale

No studies to date have examined health literacy among lesbian, gay, and bisexual (LGB) individuals, nor considered whether LGB-specific health literacy might be a contributing factor to well-documented health disparities in LGB populations. This pilot study gathered online survey data from a national convenience sample of 232 LGB adults age 40 and older. A scale developed specifically for this study had 10 items related to general health literacy and 10 items related to LGB-specific health information and skills. Factor analysis revealed that the two subscales were distinct and internally consistent, and accounted for 66% of the variance. Higher LGB health literacy was associated with greater likelihood of coming out to the healthcare provider, reporting better overall health, and having healthcare providers who were knowledgeable about LGBT issues. Greater age was associated with lower general health literacy, but was not associated with LGB literacy. Respondents who had worked in healthcare settings had higher levels of both LGB and general health literacy. Potential differences by gender on sociodemographic and health variables were identified that need to be examined in larger, more diverse samples.

Risk of Type 2 Diabetes Among Lesbian, Bisexual, and Heterosexual Women: Findings From the Nurses' Health Study II

OBJECTIVE

Lesbian and bisexual (LB) women are more likely than heterosexual women to exhibit risk factors for type 2 diabetes, but studies estimating the burden of type 2 diabetes among LB women are uncommon and limited to cross-sectional designs. This study investigated incidence of type 2 diabetes in LB women and heterosexual women in a large, longitudinal U.S. cohort.

RESEARCH DESIGN AND METHODS

Women participating in the Nurses' Health Study II (NHS II) ages 24-44 years in 1989 were prospectively followed through 2013. Self-reported clinician diagnosis of type 2 diabetes was assessed every other year to identify incidence. Of the participants, 1,267 identified as lesbian or bisexual and 92,983 identified as heterosexual. Cox proportional hazards regression was used to model incidence of type 2 diabetes.

RESULTS

LB women had a 27% higher risk of developing type 2 diabetes than heterosexual women (adjusted incidence rate ratio [IRR] 1.27, 95% CI 1.05, 1.54). Differences between LB women and heterosexual women in risk of type 2 diabetes were greater during younger ages (sexual orientation-by-age interaction, P < 0.001). BMI mediated the relationship between sexual orientation and type 2 diabetes; the IRR was completely attenuated when BMI was added to the model (IRR 0.85, 95% CI 0.70, 1.03).

CONCLUSIONS

Findings indicate that LB women develop type 2 diabetes at younger ages than heterosexual women. Higher BMI in LB women is an important contributor to this disparity. Public health and clinical efforts to prevent, detect, and manage obesity and type 2 diabetes among LB women are warranted.

Comparing women with and without disabilities in five-site "Healthy Weight" interventions for lesbian/bisexual women over 40

BACKGROUND

Lesbian/bisexual women with physical disabilities (LBPD) are an under-studied population.

OBJECTIVES

This study compared LBPD to LB women without physical disabilities as defined by the Americans with Disabilities Act on socio-demographic variables, health characteristics, and quality of life, physical activity, weight, and nutrition outcomes following a health intervention.

METHODS

Data came from the Healthy Weight in Lesbian and Bisexual Women Study (HWLB) where 376 LB women were recruited into five geographically dispersed interventions. Baseline data were examined to compare women with and without physical disabilities as defined by the ADA, and pre/post intervention data were analyzed for differences in treatment outcomes including quality of life, physical activity, nutrition, and body size.

RESULTS

Compared to women without disability, LBPD were more likely to be bisexual or another sexual identity than lesbian, single, report poor or fair health status, postmenopausal, and had a higher body mass index and waist circumference to height ratio. LBPD women were less likely to work and to drink heavily, and reported reduced physical and mental health quality of life. In spite of these differences, after the intervention, LBPD had similar outcomes to women without disabilities on most measures, and were more likely to show improvements in physical quality of life and consumption of fruits/vegetables.

CONCLUSIONS

Although different from women without disabilities on many socio-demographic and health variables at baseline, the study suggests that LBPD have similar outcomes to women without disabilities, or may even do better, in group health interventions.

The "Something Else" of Sexual Orientation: Measuring Sexual Identities of Older Lesbian and Bisexual Women Using National Health Interview Survey Questions

BACKGROUND

Terminology related to sexuality and gender is constantly evolving, and multiple factors are at play when individuals answer questions on surveys.

METHODS

We examined patterns of responding to the National Health Interview Survey (NHIS) sexual identity questions in a multisite health intervention study for lesbian and bisexual women aged 40 to 84 years.

RESULTS

Of 376 participants, 80% (n = 301) chose "lesbian or gay," 13% (n = 49) selected "bisexual," 7% (n = 25) indicated "something else," and 1 participant chose "don't know the answer." In response to the follow-up question for women who said "something else" or "don't know," most (n = 17) indicated that they were "not straight, but identify with another label." One participant chose "transgender, transsexual, or gender variant," five chose "You do not use labels to identify yourself," and three chose "you mean something else." Lesbian, bisexual, and "something else" groups were compared across demographic and health-related measures. Women who reported their sexual identity as "something else" were younger, more likely to have a disability, more likely to be in a relationship with a male partner, and had lower mental health quality of life than women who reported their sexual identity as lesbian or bisexual.

CONCLUSIONS

Respondents who answer "something else" pose challenges to analysis and interpretation of data, but should not be discarded from samples. Instead, they may represent a subset of the community that views sexuality and gender as fluid and dynamic concepts, not to be defined by a single label. Further study of the various subsets of "something else" is warranted, along with reconsideration of the NHIS question options.
