Obesity weighs America down
Obesity rates in the United States continue to worsen. So, too, does economic inequality. Are these trends related?
After remaining essentially flat in the 1950s and 1960s, the prevalence of obesity doubled in adults and tripled in children between the 1970s and 2000. According to new data from the Centers for Disease Control and Prevention, the epidemic shows no signs of abating. Nearly 4 out of 10 adults are obese; for children, it’s nearly 2 out of 10. Most 2-year-olds today will develop obesity by age 35, according to a recent projection from our colleagues at Harvard.
The obesity epidemic affects every region of the country and every demographic group. But rates have increased the fastest among low-income Americans and racial minorities, exacerbating pre-existing health disparities.
Weight-related complications like hypertension, fatty liver, orthopedic problems, sleep apnea and Type 2 diabetes are bad enough when they strike in middle age. But they have become relatively commonplace at pediatricians’ practices across the country. In adults, obesity substantially increases the risk for some of the most feared illnesses, like heart disease, cancer and Alzheimer’s. At all ages, obesity is associated with social isolation, depression and other major mental health problems.
Beyond the toll of human suffering, obesity and diet-related diseases impose massive and rapidly growing economic costs.
According to the American Diabetes Association, the annual cost of diabetes in 2017 was $327 billion, including $237 billion in direct medical expenditures and $90 billion in reduced worker productivity. (More than 90 percent of diabetes cases are Type 2, which is strongly associated with obesity.) The total impact of obesity and its related complications on the United States’ economic output has been estimated at between 4 percent and 8 percent of gross domestic product. Even on the lower end, that’s comparable to the 2018 defense budget ($643 billion) and Medicare ($588 billion).
This economic burden hits low-income and otherwise disadvantaged populations the hardest, exacerbating income and wealth inequality. With insulin now costing up to $900 a month, a diagnosis of diabetes can mean financial ruin for a low-wage worker, especially if it results in uncompensated sick days or underemployment. And as disposable income declines, so too does the ability to afford a nutritious diet, creating a vicious cycle of poverty and dietrelated disease.
Obesity doesn’t just hurt individuals’ pocketbooks; it also affects the national budget deficit. The epidemic substantially increases federal entitlement spending for medical costs through Medicare, Medicaid and Supplemental Security Income, while the resulting lower worker productivity reduces tax revenues.
Seventy percent of American adults are at least overweight, and body weight is strongly influenced by biology; we can’t blame individuals and expect personal responsibility to solve the problem. Instead, we need the government to pass a suite of policy changes to encourage healthy diets.
Right now the government is doing the opposite. Farm policies have made low-nutritional commodities exceptionally cheap, providing the food industry with enormous incentive to market processed foods comprised mainly of refined grains and added sugars. In contrast, vegetables, whole fruits, legumes, nuts and high-quality proteins are much more expensive and, in “food deserts,” often unavailable. Processed foods are heavily advertised, even in educational materials directed at young children. And as cheap calories have flooded the environment, opportunities to burn off those calories at school, in recreation and through physically active modes of transportation have declined.
The broad outlines of a healthy diet are clear. A recent study in Journal of the American Medical Association found that people can lose meaningful amounts of weight and lower their risk of heart disease by limiting sugar, refined grains and processed foods. Here are some steps that could move us from a disease-producing dietary environment to a health-promoting one:
u Establish a federal commission to coordinate obesity policy, which is now fragmented among numerous federal, state and local agencies. This commission would serve as a counterweight to the corrosive political influence and manipulative marketing practices of “Big Food” manufacturers.
u Adequately fund obesity research into innovative approaches for prevention and treatment, beyond the conventional focus on eating less and moving more.
u Impose a tax on processed foods, and use the proceeds to subsidize whole foods.
u Prioritize the quality of the nutrition in the National School Lunch Program and Supplemental Nutrition Assistance Program. Despite some recent improvements in school lunches, too often, cafeterias still look like fast food courts.
u Ban junk food advertising to young children, as recommended by the American Academy of Pediatrics and practiced in some European countries.
These policies would help us reverse the obesity epidemic, improve the health and financial well-being of millions, decrease inequality and halt the decline in life expectancy.
