Conceptualizing Geosexual Archetypes: Mapping the Sexual Travels and Egocentric Sexual Networks of Gay and Bisexual Men in Toronto, Canada

Abstract

Six geosexual archetypes were identified: hosters, house-callers, rovers, privates, travellers, and geoflexibles, each with different characteristic profiles. Prioritizing interventions to hosters, rovers, and geoflexibles may reduce sexually transmitted infection transmission.Supplemental digital content is available in the text.

Geographic Mobility, Place Attachment, and the Changing Geography of Sex among African American and Latinx MSM Who Use Substances in Los Angeles

“…Different groups of people may interact with these apps [49], and the places that people interact may also be more diverse. These changes likely alter the geography of sexual networks and HIV transmission potential [50]. Past research has suggested that MSM using geo-social apps had higher rates of drug and alcohol use, and higher sexual behaviors implying HIV transmission compared with non-app using MSM [51].…”

Evaluating the sensitivity of jurisdictional-heterogeneity and jurisdictional-mixing in national-level HIV prevention analyses: Context of the U.S. Ending the HIV Epidemic goal.

“…We evaluated the sensitivity of jurisdictional variations in access to PrEP by implementing scenarios that used the national PrEP coverage for every jurisdiction and jurisdiction-speci c PrEP coverage. To test the sensitivity of jurisdictional-mixing, we evaluated scenarios with varying levels of mixing, using data from behavioral surveys and phylogenetic studies [20][21][22][23][24][25] to set the range of values. We discuss these scenarios under Scenarios modeled.…”

“…Another survey presented in study [21] about young black MSM between ages 16 to 24, states that 20% of the cases reported travelling to another region or outside the state of Mississippi. Study [24] which conducted interviews with MSM from Toronto, Canada, states that 30% of the study's participants had sex with partners outside of their town. Study of phylogenetic analysis of HIV sequences in Shanghai [23] states that 33.8% of the HIV sequences analyzed were associated to infected individuals from another province.…”

“…Recent literature includes multiple jurisdiction-speci c models [9-17] and nationallevel models [18,19] that have conducted intervention analyses related to the U.S. EHE plan. The jurisdiction-speci c models cover limited EHE jurisdictions, and, each jurisdiction is evaluated independently, which ignores the interactions between jurisdictions, speci cally, the sexual partnership mixing between persons of different jurisdictions [20][21][22][23][24][25]. On the other hand, the national-level models do not consider the jurisdictional-heterogeneity in population demographics, including population size of key risk-groups such as injecting drug users and men who have sex with men (MSM) [26], and care parameters noted above, or the interactions between jurisdictions.…”

“…On the other hand, the national-level models do not consider the jurisdictional-heterogeneity in population demographics, including population size of key risk-groups such as injecting drug users and men who have sex with men (MSM) [26], and care parameters noted above, or the interactions between jurisdictions. Jurisdictional-heterogeneity in demographics and care along with partnership mixing between jurisdictions [20][21][22][23][24][25] suggest that there is potential for strategies adopted in one jurisdiction to in uence the nation-wide HIV incidence. However, the in uence of these jurisdictional interactions, in light of the EHE plan, has not been studied, and there are multiple gaps preventing such analyses.…”
