PASADENA, Calif. — A Kaiser Permanente study of nearly 200,000 children showed that children gained excess weight during the COVID-19 pandemic, especially those between 5 and 11 years old. The study was published in the Journal of the American Medical Association.
“When we compared the weight gain among children from 2019 to 2020, we found that there was more weight gained during the pandemic for youths of all ages,” said the senior author, Corinna Koebnick, PhD, of the Kaiser Permanente Southern California Department of Research & Evaluation. “And, this weight gain fell disproportionally on the youngest children. On average, 5- to-11-year-olds gained 5 extra pounds, while 16- to-17-year-olds gained 2 extra pounds. The result was an almost 9% increase in the youngest children falling into the categories of being overweight and obese.”
“As children go back to school it will be important to focus on health and physical activity to help children not carry unwanted extra weight into adulthood.”
To determine if children picked up extra weight during the pandemic, researchers analyzed the electronic health records of 191,509 members of Kaiser Permanente in Southern California who were age 5 to 17 from March 1, 2019, to January 31, 2021.
The study found that during the COVID-19 pandemic there was an increase in body weight and in the prevalence of obesity, particularly for children 5 to 11 years old.
“We need to immediately begin to invest in monitoring the worsening obesity epidemic and develop diet and activity interventions to help children achieve and maintain a healthy weight,” Dr. Koebnick said.

Woolford, MD, of the Child Health Evaluation and Research Center, University of Michigan, Northville, Mich, and Margo Sidell, ScD, of the Kaiser Permanente Southern California Department of Research & Evaluation; as well as Veronica Else, RN, of the Southern California Permanente Medical Group, Yorba Linda, Calif.; Xia Li, MSc, and Deborah Rohm Young, PhD of the Kaiser Permanente Southern California Department of Research & Evaluation; and Ken Resnicow, PhD, of School of Public Health, University of Michigan Department of Health Behavior and Health Education, Ann Arbor, Mich.
