Antimicrobial resistant E. coli before and after California Senate bill 27 (ARES): a natural experiment
This study will allow us to comprehensively evaluate the casual link between food animal use of antibiotics, food product contamination, and human disease. These findings will inform future policy interventions towards a potentially modifiable source of AMR to reduce the burden on human populations nationally and globally.
GWU/Wellcome 1 Feasibility
To collect preliminary data to support the larger Wellcome grant.
Impact of Sugary Beverage Taxes on Weight and Health Outcomes after 3-5 Years
This study uses electronic health records to determine the effects of sugary beverage taxes initiated in 4 Northern California cities compared with control cities in Northern and Southern California. Outcomes include weight change trajectories and prevalence of overweight and obesity among children and adults, and incidence of diabetes among adults with prediabetes. Pre-specified sub-analyses include examining differences by race/ethnicity, age groups, and neighborhood socioeconomic status.
Improving Blood Pressure and Treatment Strategies in Young Adults
About 20% of US young adults have high blood pressure (BP), however, the optimal BP screening and treatment strategies in young adults are unknown. Many young adults are not aware of their high BP, and are not recommended for BP lowering medication, partly due to the lack of evidence. The overall goal of this study is to determine the optimal BP screening intervals and identify subgroups of young adults with high cardiovascular risk who may benefit most from BP lowering medications.
Learning from California Senate bill 27: a natural experiment
This study complements an ongoing R01 study to provide more compelling evidence regarding the impact of SB27 by examining all major meat types (chicken, turkey, pork and beef) that may be impacted by the bill. Likewise, we include collection of the frank foodborne pathogens, Salmonella and Campylobacter, to provide additional insights into the potential effectiveness of this policy intervention.
