About

Dr. Tiffany Lemon is an epidemiologist and assistant professor of health services research at the Arizona State University's College of Health Solutions. Her research focuses on investigating how social and institutional health policies influence healthcare access and patient outcomes, both within clinical settings and beyond. She studies the effects of disruptions in insurance coverage on healthcare utilization and outcomes, particularly among people living with HIV and those with justice-involvement. Dr. Lemon's current work leverages longitudinal data and causal inference methodologies to estimate the impact of health insurance coverage on various patient outcomes, including healthcare utilization, HIV disease progression, and health-related quality of life. She employs the target trial framework to emulate hypothetical randomized trials, aiming to reduce biases and assess the effectiveness of health access strategies in real-world settings. Dr. Lemon serves as a faculty affiliate of the Center for Health Information and Research and the Southwest Interdisciplinary Research Center. Her educational background includes a bachelor's degree in biochemistry from Louisiana State University, a master's of public health in global epidemiology from Emory University’s Rollins School of Public Health, and a doctorate in population health sciences from Harvard T.H. Chan School of Public Health. She also completed a postdoctoral research fellowship as a T32 trainee at the Center for Global Health and Massachusetts General Hospital.

  BACKGROUND: Although sustained access to health care is essential, little is known about the relationship between insurance coverage and health among people born to women living with HIV (WLHIV). SETTING: Prospective cohort studies of youth and young adults born to WLHIV from 2007 to 2019. METHODS: We used adjusted generalized estimating equation models to estimate mean differences in, and relative risks (RRs) of, health-related quality of life (HR-QoL) and HIV disease measures over time by insurance status. HR-QoL scales with limited variability were dichotomized. Modified Poisson models were used to estimate RRs. RESULTS: Six hundred sixty-nine Adolescent Master Protocol (AMP) youth [66% living with perinatally-acquired HIV (PHIV), 72% Black] and 939 AMP Up/AMP Up Lite young adults (89% PHIV, 68% Black) reported insurance. Most were publicly insured (87% youth, 67% young adults). Privately insured young adults living with PHIV had lower risk of antiretroviral therapy nonadherence [adjusted RR (aRR): 0.82, 95% CI: 0.70 to 0.97] than those with public insurance. There was a lower risk of suboptimal role functioning for young adults with private insurance (aRR: 0.58, 95% CI: 0.35 to 0.97) and those unaware of their coverage (aRR: 0.41, 95% CI: 0.21 to 0.78). Young adults with private insurance had higher health perception scores than those with public insurance (adjusted mean difference: 3.87, 95% CI: 0.37 to 7.38). For youth, we observed no differences in HR-QOL and HIV disease measures by insurance. CONCLUSION: These findings suggest meaningful differences in antiretroviral therapy adherence and some HR-QoL outcomes by health insurance coverage among young adults born to WLHIV.

  codes, guided by the Behavioral Model for Vulnerable Populations. We found re-entry barriers include older age, stigma, lack of social support, inadequate information about sexual offense levels, limited housing options and access to mental health treatment to reduce sexual impulses, and re-entry information tailored to SOs. Re-entry facilitators include access to SO treatment, knowledge about services, self-efficacy, ability to self-advocate, and social support. Interventions to aid successful re-entry include pre-release counseling and classes tailored to SO needs, re-entry planning including housing resources, sexual deviance treatment, and referral to legal counseling to assist with altering assigned SO level. Specific needs and resources unique to veterans should be integrated into reentry plans. Convicted SOs often lack information and assistance to prepare for life after release, putting them at increased risk of homelessness, emotional difficulties, and financial hardship. Failure to recognize the unique needs of this population, and to leverage resources, creates a public health risk as it increases the likelihood that SOs will recidivate. Veterans who are SOs have unique resources available to them through the Veterans Administration such as SO treatment and peer-support specialists. Nevertheless there are additional steps that could be beneficial, such as timely provision of information, creating more opportunities for treatment, and providing more housing options.
