Professor 'thinks around the edges' of obesity problem
Research looks at complex interactions between human biology, culture
As an anthropology graduate student in the late 80s, Alexandra Brewis Slade carried out field projects in the Pacific Islands on women’s fertility and family planning. While Pacific Islanders at that time were among some of the most overweight populations on earth, she never heard obesity mentioned as a health problem even once. The islanders scolded her for being “too skinny” to attract a husband.
When she moved to expand a Samoan body image project at the University of Auckland in the early 90s, a colleague warned her that obesity was a marginal area for a social scientist to work in, a bit odd and freakish, and its explicit study was probably not the best career move.
Brewis Slade persisted, going on to study the cultural aspects of a high rate of school children’s obesity in rural Georgia and central Mexico, many of whom were at high risk for being obese. Now a widely-cited expert, she has been working on comparative studies of obesity, based on field research in a broad array of countries, such as Paraguay, New Zealand and Fiji.
The recipient of a Rockefeller Foundation pre-doctoral fellowship and an Andrew W. Mellon post-doctoral fellowship, she has published 55 papers and three books, including “Obesity: Cultural and Biocultural Perspectives” in 2011. She is director of ASU’s School of Human Evolution and Social Change and director of operations for the ASU-Mayo Obesity Solutions Initiative.
Brewis Slade notes that in a stunningly short time, obesity has gone from being considered an aberration in both popular culture and scientific circles to being perceived as a massive global threat. Unlike many global calamities such as climate change, no one seemed to notice the dramatic rise in obesity until it was well under way.
“Obesity is arguably one of the greatest public health challenges we face, infiltrating almost every aspect of our lives,” says Brewis Slade. “It shapes whether we get into college, the job offers and promotions we get, how much money we make, our access to health care, our romantic relationships. We are bombarded in the media with messages about the need to be slim and lose weight.
“We associate obesity with moral failure, with a lack of control, laziness and lack of ambition. The stigma of being obese is profound, and it causes tremendous emotional suffering. The social cost is just as important to address as the health cost.”
Cruel comments about weight are socially acceptable in many circles, and are a leading factor in childhood bullying, she says.
She also has found that globalization has spread the stigma associated with obesity from the western world to other parts of the world, including regions that previously viewed large body size in a neutral or positive light. Her research shows that negative media and public health messages about obesity are so powerful that they overshadow the positive support of family and friends in shaping how people feel about their large body size.
Her most recent work on obesity-related stigma particularly appears to have hit a cultural nerve. Her comment, “Of all the things we could be exporting to help people around the world, really negative body image and low self-esteem are not what we hope is going out with public health messaging,” was quote of the day in the New York Times and was mentioned on NBC’s “Saturday Night Live,” which she notes with good humor.
Her research team’s work on obesity also has focused on university students, based on research conducted at ASU.
They have confirmed that obesity is socially contagious and the risk of a woman’s obesity rises if her friends and family members are obese. Shared eating and exercising habits may have the strongest correlation. Currently, her team is working with a start-up company to design ways of using smart phones to connect friends and family to exercise together.
“There are lots of reasons why we gain weight and we know that telling people to ‘eat less and exercise more’ doesn’t work. We’re swimming upstream with that approach because people are working long hours, they don’t have time to exercise or make home-cooked meals. We have to look at what’s possible to change.
“Instead of blaming people for their condition, we need to step back and look at the structure of our cities, our neighborhoods, our schools and our campuses, that shape health at every level.”
She works with ASU students enrolled in research practicum classes to do research on the campus, such as surveys, focus groups and interviews with other students. Fat stigma is surprisingly high at ASU, she says; about 20 percent of students would rather be blind than obese. Her work with undergraduates has a view to designing more healthful campuses, from the perspective of people’s norms and behaviors related to weight, exercise and nutrition.
Brewis Slade’s research is ultimately concerned with the complex interactions between human biology and culture, looking at human health in the context of massive transformational processes, such as globalization and climate change. She enjoys working in diverse collaborative teams, a factor that led her to join ASU in 2006.
“ASU is a fantastic place for someone like me who thinks around the edges of problems,” she says. “I’m inspired and invigorated by the transdisciplinary environment at ASU. It’s an energetic, exciting place and I can’t think of anywhere else I’d rather be.”
She believes the partnership with Mayo makes it possible, for the first time, for a university to think of tackling the challenge of obesity on a global scale.
“What makes ASU able to attempt this is the comprehensive nature of our expertise, and the scale and scope of our collective research. We have people with talent and expertise that can be applied to almost any aspect of the complicated problem of obesity, from the built environment, to food choices, to genetics. ASU’s coverage is unmatched in the volume of different ways we can devise to tackle the problem.
“Partnering with Mayo gives us additional access to talent in the medical understanding and treatment of obesity. This provides us with a truly massive shared toolkit to address the complicated challenge of obesity.”
