Real progress has been made in tackling the epidemic of childhood obesity since the first California Childhood Obesity Conference was held 20 years ago, but there is more work to be done.

“Collectively, we have come so far,” UC Nutrition Policy Institute Director Lorrene Ritchie told an audience of 1,025 public health, nutrition education, research, and other professionals at the event in Anaheim in July 2019. NPI was one of six conference hosts.

In the last 20 years:

• Federal school meal standards have been revised so that the food children eat at school is healthier than the lunches they bring from home.
• Sugar-sweetened beverages are no longer available to students during the school day.
• Foods provided by the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) are healthier and give mothers incentive to breast feed their babies.
• The Supplemental Nutrition Assistance Program (SNAP) education component is now linked to policy, systems and environmental changes.
• The Child and Adult Care Food Program now provides healthier meals and snacks to children in childcare centers and homes across the country. 

The average quality of the diet of American children has improved, but the rate of childhood obesity in the United States is still too high.

According to the Centers for Disease Control and Prevention, 18.5% of U.S. children and adolescents 2 to 19 years old are obese – about 13.7 million youth in all. The rates trend higher in minority communities, with 25.8% of Latinx youth and 22% of African American youth obese. Obesity is also more prevalent among children in families with low incomes.

Obesity, which is defined in children as a body mass index at or above the 95th percentile of CDC growth charts, is associated with poorer mental health status, reduced quality of life, and increased prevalence of diabetes, heart disease, stroke and some types of cancer.

Vice president of UC Agriculture and Natural Resources, Glenda Humiston, the solution to the obesity epidemic will be multidisciplinary.

The vice president of UC Agriculture and Natural Resources, Glenda Humiston, pledged the organization's commitment to community health and wellbeing at the Childhood Obesity Conference. UC ANR is the umbrella organization of the Nutrition Policy Institute, UC CalFresh Healthy Living, UC Cooperative Extension, 4-H Youth Development, the UC Master Gardener Program and the California Naturalist Program, among others.

“Going forward, solutions to the obesity epidemic are multidisciplinary,” Humiston said. “NPI does world class work in conducting research to influence nutrition policy. We need to harness 4-H. Master Gardeners are increasingly focusing on edible gardens. CalNat is getting people out into nature. We are finding synergies in community wellness.”

Humiston has dedicated UC ANR resources to finding and implementing solutions to the obesity crisis.

“I'm looking forward to working with all of you – public and private organizations – to design a way to move forward,” she said.

The opening keynote presentation at the conference featured Patricia Crawford, NPI's Senior Director of Research emeritus, a pioneer in addressing the growing problem of childhood obesity during her long career. Beginning in the 1970s, she recognized that childhood obesity was on the rise and launched several studies to search for the causes and potential solutions.

In one study, Crawford followed a group of 9-year-old African American girls over a period of 10 years to determine why these youth were growing up heavier than other adolescents.

“Finally, we began to get some answers,” Crawford said. “We learned obesity wasn't the children's fault. They were living in environments that made the unhealthy choice cheaper and easier to find. It's so unfair for people who have fewer resources. Health disparities has to be the No. 1 thing we are working on to address chronic disease rates in this country.”

“The solution to obesity is prevention. It's cheaper and more effective than treatment,” Crawford continued. “Healthy food is a taste that is easy to acquire if it is not preempted by junk food.”

Crawford said she honed in on the best strategies for prevention by actively listening to people struggling to make healthy choices 

“There is a chasm between research and community,” Crawford said. “We have to get people together from the research level and the policy level with folks on the ground. We need to learn from people.”
