Social Vulnerabilities and Spatial Access to Primary Healthcare through Car and Public Transportation System in the Albuquerque, NM, Metropolitan Area: Assessing Disparities through GIS and Multilevel Modeling

AbstractPrimary healthcare (PHC) is a keystone component of population health. However, inequities in public transportation access hinder equitable usage of PHC services by minoritized populations. Using the multimodal enhanced 2-step floating catchment area method and data in 2018 and 2019 for spatial access to PHC providers (n = 1166) and social vulnerability markers through census block (n = 543) and tract data (n = 226), a generalized linear mixed-effect model (GLMEM) was constructed to test the effects of sociodemographic and community area correlates on both car and bus transit spatial access to PHC in the Albuquerque, New Mexico (NM) metropolitan area. Results for bus spatial access to PHC showed lo wer access for Hispanics (B =  − 0.097 ± 0.029 [− 0.154, − 0.040]) and non-Hispanic Whites (B =  − 0.106 ± 0.032 [− 0.169, − 0.043]) and a positive association between single-family households and bus spatial access (B = 1.573 ± 0.349 [0.866, 2.261]). Greater disability vulnerability (B =  − 0.569 ± 0.173 [− 0.919, − 0.259]) and language vulnerability (B =  − 0.569 ± 0.173 [− 0.919, − 0.259]) were associated with decreased bus spatial access. For car spatial access to PHC, greater SES vulnerability (B =  − 0.338 ± 0.021 [− 1.568, -0.143]), disability (B =  − 0.721 ± .092 [− 0.862, − 0.50 9]), and language vulne...
