Research showing value of exercise before COVID-19 diagnosis earns special recognition

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.

When more isn’t more: Smaller restaurant portions left diners just as full

Restaurants in the United States are known for generous portions, often serving far more food than most adults need in a single meal. Those oversized portions have long been linked to overeating and, over time, to higher rates of obesity and chronic disease. A new study conducted in real restaurants suggests there may be a ...

Transforming sight through clinical trials

While the typical assumption would be that it takes a major academic campus to foster medical innovation, Kaiser Permanente is proving that wrong. The Kaiser Permanente Riverside Medical Center has become a hub for clinical trial innovation under the direction of Vivienne Hau, MD, PhD, a medical and surgical vitreoretinal specialist who has built a ...

Study evaluates heart disease risk prediction across Asian ethnicities

A Kaiser Permanente study found that the PREVENT cardiovascular risk equation had strong overall ability to predict 10-year cardiovascular disease risk in Asian, Native Hawaiian, and Other Pacific Islander adults. However, its accuracy differed across specific Asian ethnic subgroups and showed consistent patterns of over- and under-estimating when grouping by race and ethnicity. The study ...

Rethinking MS treatment: Why less may be more

For years, people living with relapsing forms of multiple sclerosis (MS) have depended on powerful medications to keep their disease under control. One of the most effective treatments has been rituximab, a therapy that works by depleting B cells, which are the immune cells that drive inflammation with MS. However, new research from Kaiser Permanente ...

Featured Division

Biostatistics Research

Our biostatisticians provide expert guidance on working with real-world clinical data to investigators in all of our scientific divisions.

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.
