Abstract

Background: Understanding spatial access to sexual health services will provide the foundation for future resource planning and allocation. The purpose of this study was to evaluate the potential geographic access to sexual health services in Toronto, Canada, by developing a novel accessibility index to sexual health clinics.

Methods: We created an accessibility index using the 2-step floating catchment area method to quantify neighborhood-level access to sexual health clinics. The index assumed mixed modes of urban travel through walking and public transit, as well as through driving, and was estimated at the census tract level.

Results: Census tracts were grouped into quantiles by the estimated accessibility score. Census tracts with higher accessibility scores were characterized as those with greater residential instability and lower dependency and ethnic concentration. The downtown core area has all census tracts categorized as medium, high, or very high (average [SD] score, 1.320 [0.312]), whereas the noncore area has 56.98%, 302 of 530 census tracts categorized as medium, high, or very high (average [SD] score, -0.105 [0.960]).

Conclusions: We demonstrated the benefit of using statistical methods to quantify the geographical access to sexual health services and identified neighborhoods with high and low levels of access. Findings from this study present an overview of the level of spatial access to sexual health clinics in Toronto based on clinic locations in 2018 and can be further used to characterize neighborhoods with a lower level of access and inform policy and planning decisions in the city.
