Transgender Health Disparities: Comparing Full Cohort and Nested Matched-Pair Study Designs in a Community Health Center

LGBT Health. 2014 Sep 1;1(3):177-184. doi: 10.1089/lgbt.2014.0009.

Abstract

Purpose: U.S. health surveillance systems infrequently include measures to identify transgender respondents or monitor the health of this underserved and marginalized population.

Methods: From 2001-2002, transgender and non-transgender adults were sampled at a Massachusetts clinic. Health differences were formatively examined by transgender identity using a cross-sectional, clinic-based sample (n=2,653); and a nested matched-pair subsample (n=155).

Results: Both designs produced virtually identical findings: (1) the prevalence of HIV, substance abuse, and smoking did not differ significantly for transgender and non-transgender patients; (2) transgender patients were more likely to endorse a lifetime suicide attempt and ideation compared to non-transgender patients (p<0.05); (3) transgender patients disproportionately reported social stressors (violence, discrimination, childhood abuse) relative to non-transgender patients (p<0.05).

Conclusion: Findings suggest that a nested design may provide an effective methodology for using clinical data to study transgender health, and underscore the need for routine collection of gender identity in clinical settings.
