Rauzon, visionary in community health evaluation, retires from NPI

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.
