New law mandates at least 30 minutes of recess for K-8 public school students
Last year, while working on a bill that would require California public schools to provide at least 30 minutes of recess, State Sen. Josh Newman sought the latest research on youth physical activity. Newman, whose district encompasses parts of Los Angeles, Orange and San Bernardino counties, traveled to the Bay Area to see one of the leading experts in the field.
During several visits with Newman, Hannah Thompson – a Nutrition Policy Institute senior epidemiologist and an assistant research professor in the University of California, Berkeley School of Public Health – shared the most recent science.
Both the American Academy of Pediatrics and Centers for Disease Control and Prevention recommend that children have 20 minutes or more of daily recess. But, when asked about the current “state of recess” across California, Thompson said she only knew of anecdotal evidence at the state level.
“I said, ‘You know what? I don't actually know what is going on in California,'” Thompson recalled. “I contacted a couple of colleagues who had done more national-level work on recess that included samples of California schools – but no one was really able to disaggregate what was happening in California.”
She brought up the bill during a meeting with her fellow researchers at NPI, an institute under UC Agriculture and Natural Resources.
And it turned out that Janice Kao, an NPI academic coordinator, had exactly what she needed.
CalFresh Healthy Living evaluation team provides key recess data
Kao leads a project team that evaluates local health departments' programs of CalFresh Healthy Living – California's version of the educational arm of SNAP (the federally supported Supplemental Nutrition Assistance Program).
As part of that evaluation process, Kao's team coordinates questionnaire administration at SNAP-Ed-eligible schools that are partnering with local health departments on CalFresh Healthy Living interventions, ranging from nutrition programs to physical activity initiatives. The survey asks school administrators about their current policies, environments and practices – including the provisioning of recess.
“It was just really good luck that everything was in the right place at the right time to be able to work together,” Thompson said.
At Thompson's request, Kao and her colleagues processed and cleaned that crucial piece of data, comprising responses from 153 low-income elementary schools in the 2021-22 school year.
“Just 56% of schools reported providing more than 20 minutes of recess daily,” Kao said. “So this was a situation where the data showed, ‘OK, there is some room for improvement, perhaps at that state policy level.'”
Thompson and Rebecca London, a sociologist at UC Santa Cruz, wrote a research brief detailing their analysis of the data. They describe disparities in recess time based on school size and income level of families, with students in larger, less affluent schools generally receiving less daily recess.
Thompson said those disparities are related to funding and academic inequities, as the imperative to boost test scores forced schools to increase certain classroom hours at the expense of recess time.
“We did all this work engineering physical activity out of the school day despite the tremendous body of evidence that shows physically active kids not only are healthier but can concentrate better; they have better academic performance, fewer disruptions, better classroom behavior,” explained Thompson, a former physical education teacher in Oakland. “In trying to address that academic gap, we ended up exacerbating a lot of these public health disparities.”
Virtual learning during the pandemic showed educators and parents – firsthand – the harmful effects of children staying sedentary in front of computer screens for hours. But the resulting momentum for restoring recess and time for physical activity was soon stalled as schools tried to make up for “lost time” in returning to classrooms, Thompson said.
NPI resources, expertise invaluable to lawmakers
Newman's bill, SB 291, was an attempt to lock in those recess minutes that are crucial for student health, development and scholastic performance. Both Thompson and London testified before the Senate Education Committee in April 2023, providing the senators with science-based information and context to guide their policymaking.
“Crafting policies rooted in science is critical for legislators to ensure our policies are impactful,” Newman said. “The work of Dr. Thompson and her colleagues at UC provided clear and useful guidance on the benefits of unstructured play and how to improve health and educational outcomes in California schools.”
Gov. Gavin Newsom signed SB 291 into law last October. Starting this coming school year, public elementary and middle schools across California will be required to give at least 30 minutes of recess to K-5 students – and prohibited from withholding recess as punishment.
Kao said her team was excited that their CalFresh Healthy Living evaluation data was useful for lawmakers, illustrating NPI's important role in informing evidence-based policy.
“I'm hopeful that we can use this same data set to also provide key pieces of information on other types of legislation that's in the works, or newly passed legislation,” Kao said.
Thompson said the challenge now will be ensuring schools have the resources and funding to provide quality time for young people.
“If you only have one schoolyard, and it's already dedicated to PE, what do you do now, if you have to increase your time for recess and you don't have that space?” she said.
Thompson added that she is currently applying for a grant to study how schools across California are adjusting to meet the new requirements.

Nutrition Policy Institute researcher developed techniques that help identify effective public health programs
When Suzanne Rauzon and May Wang were in the master's of public health program at the University of California, Berkeley during the mid-1980s, Wang knew that her classmate had unique brilliance to bring to their field.
“You know how you vote for the person in high school who's most likely to succeed? That was Suzanne,” said May Wang, a professor of community health sciences in the UCLA Fielding School of Public Health. “Suzanne was always ahead of every one of us; she was so visionary and forward-thinking and I think we were all – to be honest – a little bit in awe of her.”
Decades later, as Rauzon prepares to retire in January 2024 as director of community health at the Nutrition Policy Institute, she has fulfilled that exceptional promise. Her many contributions are helping communities identify the most effective programs to benefit public health.
Lorrene Ritchie, director of NPI (an institute under UC Agriculture and Natural Resources), said that Rauzon has played a pivotal role in translating research findings into community action and policy change. She added that Rauzon has brought an extraordinary combination of strategic vision for the overall direction of nutrition studies and tactical savvy to anticipate the needs of project funders and communities.
“Few people can bring both of those skills – efficiently complete the day-to-day tasks as well as be a big-picture thinker,” Ritchie said. “She has been so instrumental in contributing to NPI's impacts.”
A unique skill set to tackle complex challenges
Part of what makes Rauzon unique in her field is her extensive experience in the private sector. After attaining her master's degree, Rauzon developed a comprehensive employee worksite wellness initiative at a telecommunications company – a new set of programs that led the field in the 1990s.
“Suzanne was, is and has always been very visionary,” Wang said.
After years in the corporate space, however, Rauzon leaped at the chance to return to academia (and reunite with Wang) in 2001 at UC Berkeley's Center for Weight and Health, a precursor to NPI. Working with center co-director Patricia Crawford, Rauzon said the project to investigate the effects of sugar-sweetened beverages was a “perfect fit” for her.
Concerned with rising childhood obesity, the researchers studied the significant differences in health outcomes for students in high schools that limited access to beverages such as soft drinks, versus schools that did not.
“That field in general – looking to limit sugar-sweetened beverages – started with a focus in schools, and expanded into other environments (such as college campuses) over the years, and has continued to be a focus in public health,” Rauzon said, “all the way up to work now on limiting sugar-sweetened beverages access in other public institutions.”
Rauzon's change-management and communication skills also were crucial in studying the revolutionary School Lunch Initiative in the Berkeley Unified School District – a collaboration with chef Alice Waters' Chez Panisse Foundation and the Center for Ecoliteracy to engage young people in the growing and preparation of food. Brought in to evaluate the efficacy of the program, Wang and Rauzon found they had to alter their mindset and methods when working with partners who were responding to oft-changing circumstances.
Rauzon's cross-sector perspective, practical know-how and people skills in cultivating positive relationships with district staff and educators were instrumental in successfully completing studies with as much rigor as possible in real-world settings such as schools.
The researchers created new analytical tools to evaluate health interventions developed by communities themselves – as opposed to programs engineered by academics and applied to community members with the expectation that they would accept it.
“Most researchers, to be honest, are still striving to do that with communities,” Wang said. “It is an incredibly challenging task because communities will do what they want to do – and what they need to do – to respond to the needs of people.”
Wang, who now trains academics in community-based participatory research, said that the ground-up paradigm has been shaped by Rauzon's thinking. “A lot of the ideas I have today really came about from our work together on the School Lunch Initiative,” Wang said.
A legacy of new methods, mentoring early-career professionals
One of Rauzon's longest-running – and most complex – projects has been the evaluation of community health interventions across the country, including a variety of Kaiser Permanente initiatives to promote healthy eating and physical activity.
“What was interesting about that work was we really were trying to understand the combined effects of doing a lot of different things that are related – and to see the overall effect that can have on the community,” said Rauzon, noting that interventions ranged from nutrition classes to policy changes to park and bike-safety improvements.
Wang said some of their findings, particularly from one study in Los Angeles County, suggest that effective programs are early childhood interventions (including an emphasis on breastfeeding), home visitations by nurses and social workers to vulnerable households, and partnerships with retailers to make healthy food choices more accessible.
In the process, the researchers helped pioneer new research tools – including interdisciplinary “systems mapping” approaches in which computer scientists discern linkages among various programs and their effects, and the highly influential “community intervention dose index” concept that can be used to evaluate multiple intervention strategies within a community.
In addition to Rauzon's contributions in research and evaluation, Ritchie also highlighted her role in supervising and mentoring students and NPI staff and researchers during her 20-plus years with the UC – the role in which Rauzon takes the most pride.
“While I made a contribution to community health in effective interventions and how to measure them,” Rauzon said, “I would say personally the most rewarding part of the work I've done over the last couple of decades is seeing the growth and development and advancement of people who have worked for me and who have really taken off in their own careers – that to me has been immensely satisfying.”
As an emeritus researcher, Rauzon will continue to support NPI professionals and their research, and she added that she's excited to embark on a new partnership – with her husband, a geographer – to mitigate impacts of climate change on human and environmental health across the globe.
People interested in supporting Rauzon's legacy and the ongoing work in health and nutrition can donate to NPI's Student Fellowship, which provides students from underrepresented groups the opportunity to work on NPI research and be mentored by NPI researchers.

Nutrition Policy Institute researcher influenced obesity research, SNAP-Ed evaluation
Young people across California and the U.S. enjoy healthier, more nutritious food options at school, thanks to the contributions of Gail Woodward-Lopez, who retired on July 1 as the associate director of research at the Nutrition Policy Institute, a part of University of California Agriculture and Natural Resources.
Woodward-Lopez officially joined UC ANR in 2015, when she and other researchers at the Atkins Center for Weight and Health at UC Berkeley merged with NPI. But her association with UC ANR goes back much further, as her work at CWH was always directed by UC Cooperative Extension academics – including the research that paved the way for California's “junk food ban” in schools.
Two bills, signed in 2005, set nutrition standards in California for “competitive foods”– the items sold in vending machines and from food service a la carte (as opposed to federally subsidized school meals). That legislation – which inspired similar policy changes across the country – was informed by the work of Woodward-Lopez and her colleagues, who had looked at the financial impact of establishing those standards.
“Our study was so pivotal that I literally had people calling me from the floor of the Senate or the Assembly when they were debating that legislation,” recalled Woodward-Lopez.
Changing perceptions of population weight gain
Originally intending to pursue a career in neurobiology, Woodward-Lopez found that lab work didn't suit her temperament. Seeking to work more directly on social issues, she embarked on a public health path, with an emphasis on nutritional aspects that incorporated her interest in biological sciences.
Woodward-Lopez's early work focused on a challenge that was just beginning to catch the attention of researchers: the rapid rise in the Body Mass Index (BMI) among the U.S. population. In tracing the causes of this epidemic, she and her colleagues shifted academic and public attention toward the host of environmental factors that contribute to weight gain – instead of focusing exclusively on an individual's choice to eat healthy and be physically active.
“Two decades ago, Gail led groundbreaking work to identify the determinants of obesity when child obesity was emerging as a public health concern,” said Nutrition Policy Institute Director Lorrene Ritchie. “While we and other researchers across the nation were working on generating more evidence to inform action, she had the vision that we could use a variety of existing data – from trends to trials – to point to the main causes.”
Many of the researchers' conclusions, which were published in the 2006 book “Obesity: Dietary and Developmental Influences,” stand to this day.
Helping to set the identity and agenda of the Center for Weight and Health when it was founded in 2000, Woodward-Lopez moved policy and practice beyond educational approaches and public awareness campaigns. As she noted: “No one thinks sugar-sweetened beverages are good for you.”
“Education alone is not going to work if people do not have access to the healthy foods and opportunities for physical activity, if they're not safe in their neighborhoods, or if they can't afford the healthy options,” she explained.
Given her seminal role in the field, Kaiser Permanente sought out Woodward-Lopez as a “thought partner” on the organization's community-based obesity prevention programs and school health work.
“Gail brought deep rigor and expertise, of course, but also a super-practical, community-focused perspective to our work,” said Loel Solomon, professor of health systems science at the Kaiser Permanente Bernard J. Tyson School of Medicine. “Her integrity and values around health equity were evident in everything we did together, and our communities are so much the better for it.”
Elevating and enhancing CalFresh Healthy Living
At the Nutrition Policy Institute, the focus of Woodward-Lopez's work has been refining the evaluation and delivery of SNAP-Ed, the educational component of the Supplemental Nutrition Assistance Program (commonly referred to as “food stamps”). Known in California as CalFresh Healthy Living, SNAP-Ed represents the largest single source of ongoing funding for nutrition and physical activity promotion in the state – outside of the WIC program which serves women, infants and young children.
“CalFresh Healthy Living can really impact millions of people,” Woodward-Lopez said. “For county health departments, this is one of their main sources of funding and provides the backbone for everything else they do in nutrition and physical activity.”
But given the variety of interventions implemented by health departments in response to local needs, determining the efficacy of those efforts is a daunting task. Woodward-Lopez and her NPI colleagues have been instrumental in devising creative approaches that help pinpoint the most effective public health measures.
For example, NPI researchers found that combining school policy changes with increased opportunities for physical activity during the school day was the best strategy to encourage student fitness. They discovered that reductions in nutrition programs during the COVID-19 pandemic disproportionately affected communities of color. And they also continue to emphasize that interventions need to be tailored to the specific cultural and political conditions within a community.
“I think in all of the work we do, we try to come up with those practical applications – what does this mean for communities? How can we do this differently? How are our findings actionable?” Woodward-Lopez said.
Her contributions toward the evaluation of California Department of Public Health SNAP-Ed have impressed and inspired Lauren Whetstone, chief of CDPH's Research, Evaluation and Strategic Alignment Section, Nutrition Education and Obesity Prevention Branch.
“Gail and her team have elevated the quality of our evaluation work and the evaluation support that we provide to local health department grantees,” said Whetstone, who has worked with Woodward-Lopez for nearly a decade. “Gail contributed substantially to statewide SNAP-Ed evaluation as well, again working collaboratively to ensure high quality evaluation. Our work is all the stronger due to Gail's dedication to excellent SNAP-Ed evaluation.”
To the benefit of the field and community health, Woodward-Lopez said she plans to remain engaged in her life's work.
“I'd really like to get more involved in policy through advocacy and through doing things like writing letters to the editor or social media commentary,” she said. “I already have some ideas for some editorials I want to write.”
And while she looks forward to spending more time with loved ones, traveling, and pursuing her interests in art and music, Woodward-Lopez will remain a guiding voice for advancing public health.
“Gail's leadership in public health nutrition – even after she retires – is a testament to her dedication,” Ritchie said. “She not only has contributed to sustainable changes in California and nationally, she has been a mentor to me and so many others in the field who will strive to continue her legacy.”
People interested in supporting Woodward-Lopez's legacy and the ongoing work in health and nutrition can donate to NPI's Student Fellowship, which provides students from underrepresented groups the opportunity to work on NPI research and be mentored by NPI researchers.

UC researchers identify barriers to Earned Income Tax Credit, which provides up to $7K each year per family
About 1 out of 4 Californians who are eligible for the Earned Income Tax Credit do not actually receive it – and University of California researchers are digging deeper to learn why they are not taking up this crucial benefit, which can provide nearly $7,000 annually for each family.
“The EITC is the largest poverty alleviation program in the country for families with kids, lifting millions of people out of poverty every year,” said Rita Hamad, associate professor at the University of California, San Francisco in the Institute for Health Policy Studies. “We know from previous work – including our own studies – that the EITC is effective at improving health, including birth weight, child development, household food security, and parents' mental health.”
Hamad is the co-lead author of an article on EITC take-up, recently published in Health Affairs, which begins to answer why only 74% of Californians receive the EITC benefit for which they are eligible.
“Billions of dollars are going unclaimed by families who could really use the money to improve their families' health and well-being,” said Hamad, who is also director of UCSF's Social Policies for Health Equity Research Program.
More broadly, about 80% of eligible families across the country take advantage of the EITC, according to previous research. But those studies only looked at tax records, and do not shed light on the specific circumstances of households that missed the credit.
“What our study did was reach out to those families and start to collect some richer information on what's happening – why aren't people getting the benefit, and what can we learn to help more people get something that can make a big difference for families,” said co-lead author Wendi Gosliner, project scientist at the Nutrition Policy Institute, a program of UC Agriculture and Natural Resources.
On EITC, ‘the more we know, the better'
Surveying 411 EITC-eligible Californians with children, researchers found that roughly 25% of respondents did not receive the benefit (including the 9% that did not file taxes). And although the sample is non-representative, the study did produce some significant findings.
For example, take-up of the EITC and CalEITC (its California state counterpart) was less likely among eligible individuals who do not speak English, had no prior knowledge of the programs, and are younger.
The age factor – correlated with inexperience in tax filing – underscores the need to clarify eligibility verbiage and materials. Gosliner noted that several respondents thought all people under the age of 25 were ineligible, when in fact those under 25 who have dependents would qualify for the federal credit (for the CalEITC, all individuals over 18 are eligible).
Such findings help fine-tune the education and outreach activities of advocacy groups such as Golden State Opportunity, a nonprofit that works to create financial stability for low-income workers across California.
“Knowing that a barrier for younger people is lack of knowledge, we can increase our outreach to community colleges and other youth-serving organizations with messaging that reaches them where they are,” said Amy Everitt, president of Golden State Opportunity. “Thanks to this research we can better understand the diverse audiences we need to reach – when it comes to the EITC, the more we know, the better.”
Need for clearer tax information, better processes
The researchers are currently analyzing the qualitative data they gathered from the interviews to produce a follow-up paper. But Gosliner shared that some of the respondents' concerns were worries about owing the government, the belief that filers must pay back the EITC money, and lack of understanding about the tax system in general and the EITC specifically.
“It's very user-unfriendly,” Gosliner said. “Even the name of the program doesn't make sense to people – they don't understand it, they don't know what it means...it's like we intentionally create these hurdles to receive the benefit.”
Both Gosliner and Hamad recommended that the government simplify the tax process, while providing free, high-quality filing services in multiple languages to ensure families are receiving the benefits that can help reduce health inequities.
“Our study speaks to the fragmentation of the social safety net, with families needing to fill out multiple redundant applications to participate in each different program,” Hamad said. “A better solution would be to have government agencies coordinate with one another, so that families who are cash-strapped with limited time can fill out just one streamlined application.”

Researchers contribute recommendations for national strategy on hunger, nutrition, health
At the first White House Conference on Hunger, Nutrition and Health convened since 1969, President Biden announced on Sept. 28 a national strategy “to end hunger in America and increase healthy eating and physical activity by 2030 so fewer Americans experience diet-related diseases.” Much of the foundational research undergirding the strategy has been informed in part by the Nutrition Policy Institute, a program of UC Agriculture and Natural Resources.
“Science is the work of many – and no one study answers all the questions – but we have a tremendous body of work that has contributed to this conference, building from all the programs and changes that were made from the last conference,” said NPI director Lorrene Ritchie.
The original Nixon-era conference produced about 1,800 recommendations – and 1,600 were eventually implemented in the subsequent years, according to Stacy Dean, U.S. Department of Agriculture Deputy Under Secretary for Food, Nutrition and Consumer Services.
A litany of far-reaching programs grew from or were propelled by the 1969 conference: the School Breakfast Program, WIC (the Special Supplemental Nutrition Program for Women, Infants and Children), SNAP (the Supplemental Nutrition Assistance Program)-Ed and CalFresh Healthy Living UC, the Expanded Food and Nutrition Education Program, and more.
This history illustrates the potential for sweeping change from this 2022 conference – which gathered about 500 experts and advocates (with 1,000 more participating online) – and from the national strategy that represents the Biden-Harris administration's “playbook.”
“Does that document have everything in it that we would like? No – but, oh my goodness, if we could accomplish all the things that they've laid out, what a transformational impact it would have,” said Ritchie, adding that she was thrilled that the highest levels of government are prioritizing hunger and nutrition-related chronic disease.
Including beverages in the conversation
In the course of gathering ideas and input from across the country, conference organizers asked Christina Hecht, NPI senior policy advisor, to author and submit NPI recommendations on encouraging the public to choose water instead of sugary drinks. Those suggestions – which range from including water in the “MyPlate” dietary guideline graphic to ensuring that every public school has a water bottle-filling station – crystallized extensive, rigorous scholarship by a broad community.
“NPI's recommendations were built on lots of work by many water researchers and advocates over the years; they're based on many years of thinking by many people,” Hecht said.
Christina and Ken Hecht, NPI policy director, also submitted recommendations as part of the Sugar-Sweetened Beverage Reduction Workgroup, which brings together experts from national, state and local organizations. Several of their key proposals, such as targeting the marketing of sugary drinks and clarifying front-of-package nutrition labels, appear as recommended steps in the national strategy document.
Other nutrition policy changes compiled by Christina Hecht – like updating the Federal Food Service Guidelines used on federal properties and in federal programs – are also reflected in the national strategy, albeit without specifically mentioning sugary drinks. Nonetheless, Hecht believes doors have been opened for future discussions that could incorporate and promote healthy beverages.
“What those doors require are continuing to develop the evidence base, continuing to translate and share the evidence base, and continuing the advocacy to bring that evidence base to the attention of decision makers,” she said.
University of California setting an example
Suzanna Martinez, an NPI-affiliated researcher who attended the White House conference, said she hopes the convening generates momentum for two bills before Congress that would help alleviate food insecurity in higher education: one that provides funding for campuses to address students' basic needs, and another that reduces barriers to SNAP (Supplemental Nutrition Assistance Program, formerly known as food stamps). The national strategy document explicitly acknowledges that “SNAP's college student eligibility restrictions are out of date given the current population who seek higher education credentials.”
Martinez, an associate professor in the Department of Epidemiology and Biostatistics at University of California San Francisco, was invited to the conference because she's part of a group driving the UC's effort to halve the number of students facing food insecurity across the system by 2030. That commitment, and UC Berkeley's work on basic needs, were highlighted by Second Gentleman Douglas Emhoff during the closing plenary session.
“The work that we're doing here in California tends to set the stage for what happens in other states,” said Martinez, who also cited California's pioneering effort to provide meals for all public school students.
NPI's ongoing work evaluating universal school meals in California and other states is just one example of how its academics and staff are refining innovative programs so they can be adopted more effectively and broadly (perhaps nationally). In fact, the White House identified “healthy school meals for all” as the top strategy for improving food access and affordability, and Ritchie applauds the administration's consistent emphasis on early interventions for healthier outcomes.
“The earlier you can create healthy habits – meaning in utero all the way through childhood – the more likely you are going to have adults who don't end up with nutrition-related chronic diseases,” she explained. “The last thing you want to do is to wait until people are really sick before they start to change their habits.”
Another overarching theme that excites Ritchie is the national strategy's “whole of government” approach to addressing a host of nutrition and hunger issues. One example is how the strategy calls for agencies not traditionally associated with food to contribute to reducing waste, such as the Department of the Treasury clarifying tax benefits for businesses that donate food.
“Throughout the document, over and over again, there are countless examples of creating synergies across government agencies and with local and state governments that can help move the needle,” Ritchie said. “It's just this kind of bold call to action that we really need.”
