The Kaiser Permanente Division of Research conducts, publishes, and disseminates epidemiologic and health services research to improve the health and medical care of Kaiser Permanente members and society at large. We seek to understand the determinants of illness and well-being, and to improve the quality and cost-effectiveness of health care. Currently, DOR’s 550-plus staff is working on more than 350 epidemiological and health services research projects.
A large study of U.S. children and teens who received the Pfizer/BioNTech COVID-19 vaccine finds that it was effective through much of 2021, but waned over time, especially as the omicron variant became dominant in 2022. Teens who received a booster dose regained some protection.
Children increased their screen time by nearly 2 hours per day after the start of the COVID-19 pandemic, and an hour of that increase persisted even after some restrictions had eased, according to a new analysis in JAMA Network Open by Kaiser Permanente researchers.
A long-term Kaiser Permanente study following 1,851 adolescents who reported substance use or mood problems at a pediatric clinic found those who had access to a brief intervention and referral to treatment were less likely to have a related diagnosis 7 years later, in their 20s.
New Kaiser Permanente study is the largest and most racially and ethnically diverse to date to show an association between early obesity and puberty onset in boys and girls.
An analysis by Kaiser Permanente researchers suggests there may be clues in a child’s medical history about their risk for a substance use problem. The investigators used that research and input from parents to develop a free online risk prediction tool that anyone can use.
The Kaiser Permanente Division of Research postdoctoral research program drew one of its largest-ever classes of fellows this year, building the strength of DOR's research portfolio. Seven fellows cover fields from diet to dementia, cancer to clinical informatics, to women's and children's health, and more.
A Kaiser Permanente analysis of more than 100,000 pregnancies in Northern California finds a 25% increase in the rate of cannabis use early in pregnancy after the pandemic began in spring 2020.
KP Research Radio talks to Ai Kubo, PhD, MPH, about her research into why girls are starting puberty earlier than they have in the past, risks associated with early puberty — and potential interventions.
