First of several Kaiser Permanente mask adherence studies released in Philadelphia

Fewer than half of the people observed outdoors in Philadelphia were wearing masks correctly, according to research spearheaded by Deborah Cohen, MD, MPH, of Kaiser Permanente Southern California Department of Research & Evaluation and Philadelphia-based Studio Ludo—a nonprofit focused on building better play through research, design, and advocacy. The study found that 51% of people ...

Increasing physical activity, and health, through policy change

While physical activity is vital for the health and well-being of children and adults, people aren’t doing enough of it, said Deborah Rohm Young, PhD, MBA, of the Kaiser Permanente Southern California Department of Research & Evaluation. One way Dr. Young sought to change that was to lead an effort to create a policy statement ...

Physicians can influence people to try to lose weight

People who were overweight were less likely to have tried to lose weight if their primary care provider had not talked with them about weight loss, a Kaiser Permanente study found. “By delivering factual information on weight status, primary care providers may motivate their patients to consider weight management strategies,” said Deborah Rohm Young, PhD, ...

Obesity increases risk of death from COVID-19, particularly for men and young people

In a study published in Annals of Internal Medicine, Kaiser Permanente research shows that obesity was associated with a substantial increased risk of death from COVID-19. However, it also found that the risk of death from COVID-19 associated with obesity is not uniform among those who are obese, but instead disproportionately affects men and people ...

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.
