Being active can lower your risk of getting seriously ill with COVID, regardless of your race or the chronic conditions you may have, according to research published last year in the American Journal of Preventive Medicine.
The Kaiser Permanente Southern California findings were important, impactful, and influential. As a result, the journal editors chose the research article, “Associations of Physical Inactivity and COVID-19 Outcomes Among Subgroups,” as the American Journal of Preventive Medicine 2023 Article of the Year.
Jaejin An, PhD, was awarded the Early Career Investigator of the Year award at this year’s Health Care Systems Research Network conference held this month in St. Louis, Missouri. Dr. An is a pharmacoepidemiologist and cardiovascular outcomes researcher for the Kaiser Permanente Southern California Department of Research & Evaluation whose work focuses on disease management, ...
People born in countries with a high burden of tuberculosis (TB) and living in the United States have higher rates of TB disease, and may need more focused screening, according to new Kaiser Permanente research. The study also found higher rates of TB among patients with certain high-risk medical conditions. The study was published in Open ...
Eye specialists at Kaiser Permanente Southern California studied whether using a standardized testing criteria among younger adults could improve care, reduce unnecessary testing, and potentially reduce blindness from glaucoma. The eye specialists, working with researchers at University of Southern California, published Outcomes of Glaucoma Referrals in Adults Aged 18 to 40 years in JAMA Network ...

The latest IMPACT newsletter, which focuses on research from Kaiser Permanente Southern California, is now available! It features 11 stories on our groundbreaking research, links to over a dozen media stories, and a Q&A with a health economics investigator.
Investigators with the Division of Biostatistics Research collaborate closely with scientists from the department’s other scientific divisions, as well as physician researchers at medical centers across Kaiser Permanente Southern California. They provide expertise and guidance on study design, power and sample size calculations, data management, data analysis and interpretation, and statistical methodology.
Investigators from the division have expertise in study design and data analysis for observational studies and clinical trials to address study questions. Their expertise spans standard and modern methods that deal with complex and big data for population and causal inferences as well as disease prediction.
Each division has at least one dedicated collaborative biostatistician research scientist assigned to provide statistical guidance on its research studies. In addition, one of the collaborative biostatistician researcher scientists leads the Regional Research Statistical Support team, which supports medical center-based researchers.
