Using the Bem and Klein Grid Scores to Predict Health Services Usage by Men

Variations in gender identity and sexual orientation of university students

Background

Previous studies have shown that a small percentage of people in the general population have atypical gender identity and/or sexual orientation.

Aim

This study aimed to explore variations in gender identity and sexual orientation in university students and determine genetic factors associated with these variations.

Methods

Deviations from complete gender congruence and exclusive heterosexual orientation in 736 Japanese university students were quantitatively assessed with self-assessment questionnaires. Next, we conducted genetic tests for 80 participants who showed relatively low gender identity scores and/or atypical sexual orientation. These genetic tests consisted of repeat number analysis of the androgen receptor gene (AR) and a SKAT-O: an optimal unified sequence kernel association test, which is an exome-based rare variant association study. The results of the genetic tests were compared with the Japanese reference data and the results of our 637 control samples.

Outcomes

We calculated the gender identity and sexual orientation scores of all participants and analyzed the molecular data of 80 selected participants.

Results

The gender identity scores of 736 participants were broadly distributed: only ~15% of natal males and ~5% of natal females had the maximum score that corresponds to complete gender congruence. The sexual orientation scores also varied: ~80% of natal males and ~60% of natal females showed exclusive heterosexual orientation. We found no association between gender characteristics and AR repeat numbers. The SKAT-O showed that rare damaging variants of TDRP and 3 other genes were more common in the 80 participants than in the control group.

Clinical Implications

Our data support the view that gender is a phenotypic continuum rather than a binary trait.

Strength and Limitations

This study quantitatively assessed the gender characteristics of a large cohort of university students. Moreover, we conducted systematic screening for genetic factors associated with gender variations. The weaknesses of the study were the limited analytic power of the questionnaires, the relatively small sample for molecular analyses, and incomplete clinical information and relatively advanced ages of the control group.

Conclusion

This study revealed significant variations in gender identity and sexual orientation in university students, which may be partly associated with variants in TDRP or other genes.

The Operationalisation of Sex and Gender in Quantitative Health-Related Research: A Scoping Review

Current trends in quantitative health research have highlighted the inadequacy of the usual operationalisation of sex and gender, resulting in a growing demand for more nuanced options. This scoping review provides an overview of recent instruments for the operationalisation of sex and gender in health-related research beyond a concept of mutually exclusive binary categories as male or masculine vs. female or feminine. Our search in three databases (Medline, Scopus and Web of Science) returned 9935 matches, of which 170 were included. From these, we identified 77 different instruments. The number and variety of instruments measuring sex and/or gender in quantitative health-related research increased over time. Most of these instruments were developed with a US-American student population. The majority of instruments focused on the assessment of gender based on a binary understanding, while sex or combinations of sex and gender were less frequently measured. Different populations may require the application of different instruments, and various research questions may ask for different dimensions of sex and gender to be studied. Despite the clear interest in the development of novel sex and/or gender instruments, future research needs to focus on new ways of operationalisation that account for their variability and multiple dimensions.

Care of Sexual and Gender Minorities in the Emergency Department: A Scoping Review

STUDY OBJECTIVE

This scoping review was conducted to collate and summarize the published research literature addressing sexual and gender minority care in the emergency department (ED).

METHODS

Using PRISMA-ScR criteria, an electronic search was conducted of CINAHL, Embase, Ovid Medline, and Web of Science for all studies that were published after 1995 involving sexual and gender minorities, throughout all life stages, presenting to an ED. We excluded non-US and Canadian studies and editorials. Titles and abstracts were screened, and full-text review was performed independently with 4 reviewers. Abstraction focused on study design, demographics, and outcomes, and the resulting data were analyzed using an ad hoc iterative thematic analysis.

RESULTS

We found 972 unique articles and excluded 743 after title and abstract screening. The remaining 229 articles underwent full-text review, and 160 articles were included. Themes identified were HIV in sexual and gender minorities (n=61), population health (n=46), provider training (n=29), ED avoidance or barriers (n=23), ED use (n=21), and sexual orientation/gender identity information collection (n=9).

CONCLUSION

The current literature encompassing ED sexual and gender minority care cluster into 6 themes. There are considerable gaps to be addressed in optimizing culturally competent and equitable care in the ED for this population. Future research to address these gaps should include substantial patient stakeholder engagement in all aspects of the research process to ensure patient-focused outcomes congruent with sexual and gender minority values and preferences.

The Role of the Medicaid Expansion in the Use of Preventive Health Care Services in California Men

Men’s use of preventive care services may be constrained due to a number of factors including lack of health care insurance. California used the Medicaid expansion provisions of the Affordable Care Act (ACA) to enroll low-income men between the ages of 18 and 64 years in publicly funded health insurance. Most studies on the effect of the ACA on health care services have focused on racial/ethnic differences rather than gender. Data from the California Health Interview Survey for the 2015–2016 survey period were used to model the use of preventive health care services in the year prior to interview. Population weights were used in the analysis which was done using PROC SURVEY LOGISTIC in SAS software, version 9.4. The sample consisted of men between the ages of 18 and 64 years (N = 6,180). Of these 66% (n = 4,088) reporting receiving any preventive care services in the year prior to interview. The largest proportions of respondents fell into the youngest group aged 18–25 (17%) followed by the oldest group aged 60–64 (16.9%); 43% reported they were married, 57% had incomes at greater than 300% of the federal poverty level. There was no effect of race or ethnicity on receiving preventive care services. Having a chronic condition such as hypertension or diabetes was associated with a greater odds of receiving preventive care. Expanding Medicaid to include low-income men below the age of 65 is associated with increased use of preventive health care, especially among those with chronic conditions.
