[PMID: 38690117 PMCID: PMC11059336 DOI: 10.1016/j.ssmph.2024.101664] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 02/22/2024] [Accepted: 03/20/2024] [Indexed: 05/02/2024] Open
Abstract
Intersectional multilevel analysis of individual heterogeneity and discriminatory accuracy (I-MAIHDA) is an innovative approach for investigating inequalities, including intersectional inequalities in health, disease, psychosocial, socioeconomic, and other outcomes. I-MAIHDA and related MAIHDA approaches have conceptual and methodological advantages over conventional single-level regression analysis. By enabling the study of inequalities produced by numerous interlocking systems of marginalization and oppression, and by addressing many of the limitations of studying interactions in conventional analyses, intersectional MAIHDA provides a valuable analytical tool in social epidemiology, health psychology, precision medicine and public health, environmental justice, and beyond. The approach allows for estimation of average differences between intersectional strata (stratum inequalities), in-depth exploration of interaction effects, as well as decomposition of the total individual variation (heterogeneity) in individual outcomes within and between strata. Specific advice for conducting and interpreting MAIHDA models has been scattered across a burgeoning literature. We consolidate this knowledge into an accessible conceptual and applied tutorial for studying both continuous and binary individual outcomes. We emphasize I-MAIHDA in our illustration, however this tutorial is also informative for understanding related approaches, such as multicategorical MAIHDA, which has been proposed for use in clinical research and beyond. The tutorial will support readers who wish to perform their own analyses and those interested in expanding their understanding of the approach. To demonstrate the methodology, we provide step-by-step analytical advice and present an illustrative health application using simulated data. We provide the data and syntax to replicate all our analyses.

Abstract
The intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) approach is gaining prominence in health sciences and beyond, as a robust quantitative method for identifying intersectional inequalities in a range of individual outcomes. However, it has so far not been applied to longitudinal data, despite the availability of such data, and growing recognition that intersectional social processes and determinants are not static, unchanging phenomena. Drawing on intersectionality and life course theories, we develop a longitudinal version of the intersectional MAIHDA approach, allowing the analysis not just of intersectional inequalities in static individual differences, but also of life course trajectories. We discuss the conceptualization of intersectional groups in this context: how they are changeable over the life course, appropriate treatment of generational differences, and relevance of the age-period-cohort identification problem. We illustrate the approach with a study of mental health using United Kingdom Household Longitudinal Study data (2009-2021). The results reveal important differences in trajectories between generations and intersectional strata, and show that trajectories are partly multiplicative but mostly additive in their intersectional inequalities. This article provides an important and much needed methodological contribution, enabling rigorous quantitative, longitudinal, intersectional analyses in social epidemiology and beyond.

Zheng S, Armstrong HL. Exploring the association between sexual motivation and quality of life in China and the United Kingdom. PLoS One 2023; 18:e0293566.

Abstract
Previous research suggests that different sexual motivations may be associated with different sexual behaviours and levels of sexual satisfaction, and these may vary with cultural differences. As such, sexual motivations and cultural factors might also be associated with quality of life (QoL); however, this has not yet been explored. Using a biopsychosocial approach, this study aimed to explore associations between sexual motivation and quality of life between participants in the United Kingdom and China. 276 participants (143 British, 133 Chinese, mean age = 21.5 years) completed an anonymous online survey including validated measures for sexual motivation (YSEX?-SF) and QoL (WHOQOL-BREF). In multivariable linear regressions, pleasure motivations for sex were associated with increased physical health QoL (aOR = 0.20, 95%CI:.15-.65), while love and commitment motivations were associated with increased psychological health QoL (aOR = 0.13, 95%CI:.01-.43). Both love and commitment motivations (aOR = 0.21, 95%CI:.09-.35) and pleasure motivations (aOR = 0.20, 95%CI:.08-.36) were associated with increased social support QoL. A significant interaction was found between emotional motivations and culture (p = 0.037) such that among individuals from China, emotional motivations (i.e., love and commitment and expression) were positively associated with psychological QoL. This suggests culture may differentially affect how sexual motivations are associated with QoL and warrants further consideration in future research.

Abstract
AbstractIntersectional approaches have become increasingly important for explaining educational inequalities because they help to improve our understanding of how individual experiences are shaped by simultaneous membership in multiple social categories that are associated with interconnected systems of power, privilege, and oppression. For years, there has been a call in psychological and educational research for quantitative approaches that can account for the intersection of multiple social categories. The present paper introduces the Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) approach, a novel intersectional approach from epidemiology, to study educational inequalities. The MAIHDA approach uses a multilevel model as the statistical framework to define intersectional strata that represent individuals’ membership in multiple social categories. By partitioning the variance within and between intersectional strata, the MAIHDA approach allows identifying intersectional effects at the strata level as well as obtaining information on the discriminatory accuracy of these strata for predicting individual educational outcomes. Compared to conventional quantitative intersectional approaches, MAIHDA analyses have several advantages, including better scalability for higher dimensions, model parsimony, and precision-weighted estimates of strata with small sample sizes. We provide a systematic review of its past application and illustrate its use by analyzing inequalities in reading achievement across 40 unique intersectional strata (combining the social categories of gender, immigrant background, parental education, and parental occupational status) using data from 15-year-old students in Germany (N = 5451). We conclude that the MAIHDA approach is a valuable intersectional tool to study inequalities in educational contexts.

Abstract
This paper uses two surveys to examine sexual identity-behavior discordance in Canada. The first is the Sex in Canada survey (SCS), which is a private survey of 2,303 Canadians. The second is the 2015-2016 Canadian Community Health Survey (CCHS), which is a large nationally representative government-administered survey with 109,659 respondents. Results from the CCHS show that identity-behavior discordance and overall rates of same-sex contact are lower in Canada than in the US, UK, or Australia. An estimated .7 percent of males and 2.7 percent of females aged 15-64 who had had lifetime sex identified as heterosexual yet have had same-sex contact, figures which equate to an estimated 65,700 males and 255,100 females. Few demographic factors were associated with discordance. Results from the SCS show that about two-thirds of heterosexuals with identity-behavior discordance were moderately supportive of LGBQ rights and one-third were moderately homophobic. Future research will need to uncover why a lower proportion of Canadians report same-sex partners and identity-behavior discordance than their counterparts in the US, UK, or Australia. Cet article utilise deux enquêtes pour examiner la discordance entre l'identité sexuelle et le comportement au Canada. La première est l'enquête Sex in Canada (SCS), qui est une enquête privée menée auprès de 2 303 Canadiens. La seconde est l'Enquête sur la santé dans les collectivités canadiennes (ESCC) de 2015-2016, qui est une grande enquête représentative à l'échelle nationale administrée par le gouvernement auprès de 109 659 répondants. Les résultats de l'ESCC montrent que la discordance identité-comportement et les taux globaux de contacts entre personnes de même sexe sont plus faibles au Canada qu'aux États-Unis, au Royaume-Uni ou en Australie. On estime que 0,7 % des hommes et 2,7 % des femmes âgés de 15 à 64 ans ayant eu des rapports sexuels au cours de leur vie se sont identifiés comme hétérosexuels, mais ont eu des contacts avec des personnes du même sexe, ce qui correspond à environ 65 700 hommes et 255 100 femmes. Peu de facteurs démographiques étaient associés à la discordance. Les résultats de l'enquête SCS montrent qu'environ deux tiers des hétérosexuels présentant une discordance entre identité et comportement étaient modérément favorables aux droits des LGBQ et qu'un tiers était modérément homophobe. Les recherches futures devront découvrir pourquoi une plus faible proportion de Canadiens déclarent avoir des partenaires de même sexe et être en désaccord avec leur identité et leur comportement que leurs homologues aux États-Unis, au Royaume-Uni ou en Australie.

Prevalence and Sociodemographic Correlates of Identifying as Mainly Heterosexual: Stability and Change across Three Cohorts of Australian Women. ARCHIVES OF SEXUAL BEHAVIOR 2021; 50:3459-3477.

Abstract
In recent decades, the ways in which sexual minorities identify have changed dramatically. In response, social and health surveys have begun offering a greater range of response options within sexual orientation questions-for example, intermediate categories for "mainly heterosexual" and "mainly lesbian/gay" alongside the more common response options of "heterosexual," "bisexual," and "lesbian/gay." Recent studies indicate that women who identify as "mainly heterosexual" report poorer health, greater health-risk behaviors, and higher rates of victimization than women identifying as "exclusively heterosexual." However, we know very little about the demographic profile of women who choose the "mainly heterosexual" identity label compared to the adjacent "exclusively heterosexual" or "bisexual" labels or about changes over time in the prevalence and correlates of "mainly heterosexual" identification. This study addressed these knowledge gaps by modeling unique, high-quality survey data from three national cohorts of Australian women (Australian Longitudinal Study on Women's Health, 2000-2017, n = 76,930 observations). Consistent with the facilitative environments model, we document stark cross-cohort increases in the percentage of Australian women identifying as "mainly heterosexual"-from ∼1% of those born in 1946-1951 to ∼26% of those born in 1989-1995, coinciding with comparable declines in the percentage of women identifying as "exclusively heterosexual." We also found evidence of cohort differences in the associations between key sociodemographic factors-such as age, education, and socioeconomic status-and the likelihood of women identifying as "mainly heterosexual." Finally, our results indicate that same-sex sexual attractions were more strongly associated with "mainly heterosexual" identification than was same-sex sexual behavior.

Abstract
We analyze the expression of sexualities in the contemporary United States using data about disclosure on social media. Through the Facebook advertising platform, we collect aggregate counts encompassing 200 million Facebook users, 28% of whom disclose sexuality-related information. Stratifying by age, gender, and relationship status, we show how these attributes structure the propensity to disclose different sexual identities. We find a large generational difference; younger social media users share their sexualities at high rates, while for older cohorts marital status substitutes for sexual identity. Consistent with gendered expectations, women more often express a bisexual interest in men and women; men are more explicit about their heterosexuality. We interpret these variations in sexuality disclosure on social media to reflect the salience of sexual identity, intersected at times with availability. Our study contributes to the sociology of sexuality with a quantitative analysis, using novel digital data, of how sexuality is signaled socially.
