Biosocial Factors Shaping Perceptions of Disease Risk Among a Community-Based Sample of Sexual and Gender Minority People Living in Toronto During the COVID-19 Pandemic
Introduction
The COVID-19 pandemic has disproportionately affected vulnerable populations, including sexual and gender minority (SGM) people. Food insecurity, prevalent among this population, may influence perceived vulnerability to infection and related psychological outcomes. This study investigated the association between food insecurity and perceived vulnerability to infection among SGM adults in Toronto, Canada, during the third wave of the COVID-19 pandemic.
Methods
A mixed-methods study was conducted with 338 self-identified SGM adults recruited via respondent-driven sampling to complete an internet-based survey between March and July 2021. Measures included food security status, germ aversion, perceived infectability, and COVID-19 worry. Structural equation modeling (SEM) examined pathways linking food insecurity, discrimination, sleep quality, and perceived vulnerability to disease, adjusting for demographic and socioeconomic covariates.
Results
The SEM showed that discrimination predicted increased food insecurity (β = 0.30, p < 0.001) and poorer sleep quality (β = 0.26, p < 0.001). Sleep quality mediated the relationship between food insecurity and perceived vulnerability to disease (indirect effect = 0.16, p < 0.001). Discrimination had a significant total effect on perceived vulnerability to disease (β = 0.22, p < 0.001).
Discussion
These findings highlight the roles of food insecurity, discrimination, and sleep quality in shaping perceptions of disease vulnerability and risk among SGM people. Interventions addressing food security, mental health, and structural inequities are crucial for mitigating health disparities both during public health crises and in everyday life.
期刊介绍：
The American Journal of Human Biology is the Official Journal of the Human Biology Association.
The American Journal of Human Biology is a bimonthly, peer-reviewed, internationally circulated journal that publishes reports of original research, theoretical articles and timely reviews, and brief communications in the interdisciplinary field of human biology. As the official journal of the Human Biology Association, the Journal also publishes abstracts of research presented at its annual scientific meeting and book reviews relevant to the field.
The Journal seeks scholarly manuscripts that address all aspects of human biology, health, and disease, particularly those that stress comparative, developmental, ecological, or evolutionary perspectives. The transdisciplinary areas covered in the Journal include, but are not limited to, epidemiology, genetic variation, population biology and demography, physiology, anatomy, nutrition, growth and aging, physical performance, physical activity and fitness, ecology, and evolution, along with their interactions. The Journal publishes basic, applied, and methodologically oriented research from all areas, including measurement, analytical techniques and strategies, and computer applications in human biology.
Like many other biologically oriented disciplines, the field of human biology has undergone considerable growth and diversification in recent years, and the expansion of the aims and scope of the Journal is a reflection of this growth and membership diversification.
The Journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscripts of unusual interest.
