Research by Jiang, Drake, Kinuthia, and John-Stewart Assesses Differentiated Service Delivery Approaches for Postpartum Women Living with HIV
CSDE Affiliates Dr. Alison Drake (Global Health), Dr. Grace John-Stewart (Global Health, Epidemiology, Medicine, and Pediatrics), and co-authors published their research in JAIDS, “HIV viral load patterns and risk factors among women in prevention of mother-to-child transmission (PMTCT) programs to inform differentiated service delivery (DSD)”. This research was led by Dr. Wenwen Jiang (recent PhD graduate) as part of her PhD dissertation at UW and by Dr. John Kinuthia (Global Health), who led the team in Kenya. Differentiated service delivery (DSD) approaches decrease frequency of clinic visits for individuals who are stable on antiretroviral therapy (ART). It is unclear how to optimize DSD models for postpartum women living with HIV (PWLH). Authors evaluated longitudinal HIV viral load (VL) and cofactors, and modeled DSD eligibility with virologic failure (VF) among PWLH in PMTCT programs.
This analysis used programmatic data from participants in the Mobile WAChX trial (NCT02400671). Women were assessed for DSD-eligibility using the WHO criteria among general people living with HIV (receiving ART for ≥6 months and having at least one suppressed VL [<1,000 copies/mL] within the past 6 months). Longitudinal VL patterns were summarized using group-based trajectory modeling (GBTM). VF was defined as having a subsequent VL ≥1,000 copies/mL after being assessed as DSD-eligible. Predictors of VF were determined using log-binomial models among DSD-eligible PWLH.
Among 761 women with 3,359 VL results (median 5 VL per woman), a three-trajectory model optimally summarized longitudinal VL, with most (80.8%) women having sustained low probability of unsuppressed VL. Among women who met DSD criteria at 6 months postpartum, most (83.8%) maintained viral suppression until 24 months. Residence in Western Kenya, depression, reported interpersonal abuse, unintended pregnancy, nevirapine-based ART, low-level viremia (VL 200-1,000 copies/mL), and drug resistance were associated with VF among DSD-eligible PWLH. Most postpartum women maintained viral suppression from early postpartum to 24 months and may be suitable for DSD referral. Women with depression, drug resistance and detectable VL need enhanced services.
CSDE Computational Demography Working Group (CDWG) Hosts UW Soc PhD Student (11/29/23)
On November 29 from 3:30-4:30 pm, CSDE Trainee Breon Haskett will join CDWG to discuss his research. CDWG Will be Hybrid in Fall Quarter 2023. It will take place in 223 Raitt hall (The Demography Lab) on Zoom (register here). Breon Haskett is a PhD student in the Department of Sociology at UW and a T32 Fellow at CSDE. His work focuses on the intersection of industry and population processes to understand how people get by in the U.S..
Is the Grass Greener: A Wage Comparison across Racial Segregation at Home and Work
Race continues to be a strong predictor of where people live and work in the U.S. Past works show that we experience segregation to varying degrees throughout our day, not just at our residence. Yet little is known about what consequences the interaction of these segregations across two places, work and home, have for inequality. This research examines to what extent the social distance between residence and workplace holds for local economic outcomes. He uses LEHD residence and workplace characteristics data to assess the cost of the variation in diurnal segregation across Census tracts in the U.S. He develops this work in conversation with whitespaces, activity space, and wage attainment literatures. This research is part of his dissertation project that examines the composition of industries as a mechanism for population outcomes and inequality.

*New* Database on Climate Refugees
The Othering and Belonging Institute at UC Berkeley launched an interactive climate displacement database illustrating how and why over 70 percent of people displaced worldwide are from the most climate-vulnerable countries–largely from across the Global South. Explore the data here.
Postdoctoral Fellowship at UM’s Population Studies Center – Position #1
The Populations Studies Center T32 Training Programs, located at the University of Michigan Institute for Social Research, is looking to fill two postdoctoral fellowship positions with appointments beginning on or about September 1, 2024. One fellowship will be sponsored by the National Institute on Aging (NIA) and one will be sponsored by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).
CS&SS Seminar: Elizabeth Sanders on Clustered Data Analytic Options (11/29/23)
On Wednesday, Nov. 29th from 12-30-1:30, CS&SS will host Dr. Elizabeth Sanders (Associate Professor, Measurement and Statistics) in 409 Savery Hall and on Zoom (register here). In this presentation Dr. Sanders will discuss the major ways clustered data can be analyzed, especially when we only care about lower-level research questions, along with results from my own work showing how to avoid lower-level fixed effect coefficient (slope) bias, and why it’s especially important for multilevel modeling alternatives. If time permits, Dr. Sanders will also present some work on statistically comparing two predictors’ slopes from the same model, including for frequentist and Bayesian multilevel models. R code and sample data will be provided. Learn more about the talk here.
Dr. Liz Sanders is Associate Professor in the College of Education’s Measurement & Statistics program. Her research focuses on evaluating applied analytic methods for handling clustered data. Outside of work, Liz loves running.
