Obesity plagues impoverished residents in Stanislaus, Merced counties

Proof seen in valley statistics; food habits, stress contribute

May 24, 2010 

FRESNO -- The smaller the paycheck, the bigger the belly, say many researchers who study poverty and obesity.

It might seem like a paradox, but not having enough money for food doesn't mean the poor are skinny. The opposite appears to be true: The lower-income are more likely to be heavy than the well-to-do.

"Obesity is an economic issue," said Cyndi Walter, manager of the California Department of Public Health obesity-prevention program, Project LEAN.

Eating well is beyond the reach of many California residents, she said.

It's easy to make the connection in the San Joaquin Valley.

At least 20 percent of adults in the region live in poverty, and about 30 percent are obese. Statewide, 13 percent are poor and 23 percent are obese, according to U.S. Census data and the 2007 California Health Interview Survey.

Health experts say there is no shortage of reasons why poverty is a predictor for obesity -- even stress and hopelessness could be factors. Overall, it comes down to food options: Poverty not only limits choices but can discourage healthy decisions that have little to do with money, they say.

For starters, the low- income tend to live in neighborhoods that are flush with fast food restaurants and convenience stores that sell mostly junk foods, the experts say. Supermarkets are few -- and the fresh fruits, vegetables and lean meats they carry are more expensive than hamburgers, french fries and sodas.

The low-income "are buying what's available to them and affordable to them," said Genoveva Islas-Hooker, regional program coordinator for the Central California Regional Obesity Prevention Program.

People still are responsible for making the healthiest food choices possible, she said. But there, too, poverty's powers are hard to ignore.

Habits start young

Food habits begin in childhood, Islas-Hooker said. "You grow up in a household where there is limited economic means and your caregiver is purchasing food on what they can afford," she said. "You become ingrained in that type of diet and that type of pattern."

Foods high in fat and carbohydrates and those full of sugar are cheap, energy-dense, nutrient poor -- and filling, said Edie Jessup, a program development specialist who works with Islas-Hooker.

Giving children a package of Top Ramen is an inexpensive, quick meal, Jessup said. "And because it's more carbohydrates, it makes your child feel like they've had more," she said.

Fats and sugars make foods taste good, too. "We really like fat, salty and sweet," Jessup said.

Some even suspect the foods are addictive.

A number of studies are looking at the physical response to such foods, according to the California Department of Public Health. The department says introducing fats and sugars to children early isn't recommended by pediatricians. They suggest giving infants puréed vegetables before puréed fruits so they can develop a taste for the vegetables and not reject them in favor of the sweeter fruit tastes, the department says.

Researchers who study the relationship between income and poverty speculate that some of the food choices made by the poor are not strictly cost-driven.

When you're living paycheck-to-paycheck, making a healthy food choice "is just not the highest priority in life," said Paul Leigh, an expert on health and labor economics and a professor at the Center for Healthcare Policy and Research at the University of California at Davis.

Leigh is senior author of a new study that found minimum-wage workers are more likely to be obese than people who earn higher wages.

People who live on minimum wages have fewer options than higher-wage earners, Leigh said.

"There is a direct causal relationship between the wages low-income people receive and their risk of obesity," he said.

But there also is an indirect emotional reaction. Living in poverty also involves stress, Leigh said. "With a certain amount of stress and unhappiness, you want to have some quick reward," he said. A sugary soda, for example, can provide a cheap, quick emotional lift.

The fast food solution

By the same token, fast food restaurants provide an outlet for low-income families: The food is cheap, it tastes good, and there is free entertainment for the children.

"The kids love it," Leigh said.

People with higher incomes can be selective about restaurants, he said.

In some cases, eating out or serving processed foods may be the only option for a family. The stove in the apartment may not work, they may not have pots and pans to use, or they don't know how to cook.

"Half of the story is about people making smarter decisions," Islas-Hooker said. "But make sure healthy options are there."

The obesity epidemic among the poor has very little to do with individual motivation or even genetics or metabolism, said Dr. Adam Drewnowski, director of the Center for Public Health Nutrition at the University of Washington. He has specialized in the relationship between poverty and obesity for the past decade.

"Obesity is an expression of limited resources," he said. "Solutions really lie in education, instruction, access to healthy foods and being able to afford healthy foods."
