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.
A new study led by Kaiser Permanente researchers compared how well 4 different types of glucose-lowering medications reduced the risk of heart attack and stroke for patients with type 2 diabetes, providing important new information for these patients and their physicians. The study, published in JAMA Network Open in October, 2025, analyzed data collected on ...
Breast cancer survivors face a high risk of major depressive disorder, also known as clinical depression, particularly if they also have insomnia, according to findings from a new study of Kaiser Permanente members. “We determined that the risk of major depression disorder was markedly higher in breast cancer survivors than in a matched group of ...
Nearly 1 in 5 urinary tract infections (UTIs) in Southern California could be due to E. coli strains transmitted through contaminated meat, according to a new study of Kaiser Permanente Southern California members. The research also found that those living in low-income neighborhoods were at increased risk of these infections. The study was published in ...
After COVID-19 hit in 2020, some physicians within Kaiser Permanente grew concerned that their patients with diabetes weren’t achieving healthy blood sugar control.

Adolescent and young adult cancer survivors face significantly higher risks of developing chronic medical conditions compared to their peers without cancer, a new study showed. The findings were published in Cancer, the journal of the American Cancer Society. “As cancer survival rates improve for adolescent and young adult cancer survivors, their numbers are increasing,” said ...
Check out our latest issue for a roundup of our most recent research and profiles on a few of our newest postdocs. This issue features new findings on opioid tapering programs that show that patients on long-term high-dose opioids who gradually reduced their dose within 3 months faced a lower risk of overdose within a year. It also shares important recent findings that the COVID-19 vaccine does not increase the risk of tinnitus, as well as findings about patterns of breast cancer imaging and Type 2 diabetes remission.
Our behavioral scientists focus on research that has the potential to reduce disease risk by identifying modifiable risk factors and encouraging health-promoting behaviors. Faculty members have expertise in the following areas: adverse childhood experiences, cancer, chronic disease prevention and screening, diet and nutrition, mental health, obesity, physical activity, sedentary behavior, social determinants of health, and weight loss surgery and interventions.
The behavioral research portfolio includes intervention studies as well as qualitative and quantitative studies. The division also supports recruitment and other activities of the Kaiser Permanente Research Bank in Southern California.
