In 2020, the vast majority of adults in America will be overweight or obese and more than half will suffer from diabetes or pre-diabetic conditions, according to projections presented by Northwestern Medicine researchers.
Representative of all Americans, the study is based on patterns found in the National Health and Nutrition Examination Surveys (NHANES) from 1988 to 2008. The projected numbers on weight and diabetes, based on previous trends, follow.
In 2020, 83 percent of men and 72 percent of women will be overweight or obese.
Currently, 72 percent of men and 63 percent of women are overweight or obese (people who are overweight have a Body Mass Index (BMI) of 25 to 29kg/m2, people who are obese have a BMI of 30kg/m2 or greater).
In 2020, 77 percent of men and 53 percent of women will have dysglycemia (either diabetes or pre-diabetes). Currently, 62 percent of men and 43 percent of women have dysglycemia.
“…American adults need to rapidly reverse these unhealthy trends — starting today,” Huffman said. “In concert with individual choices, public health policies can be and should be effective tools to reduce smoking, increase access to healthy foods, and increase physical activity in daily life.”
More people would need to improve health behaviors related to diet, physical activity, body weight and smoking and health factors, related to glucose, cholesterol and blood pressure.
“We’ve been dealing with the obesity trend for the past three decades, but the impact we project on blood sugar is a true shock,” said Donald Lloyd-Jones, M.D., chair and associate professor of preventive medicine at the Feinberg School of Medicine, a physician at Northwestern Memorial Hospital and senior author of the study. “Those are some really scary numbers. When blood sugar goes up like that, all of the complications of diabetes come into play.”
Less than five percent of Americans currently are considered to have ideal cardiovascular health. The modest six percent improvement in cardiovascular health that is projected for 2020… wouldn’t be enough to offset the weight and diabetes problems Americans face, Huffman said. Projected improvements in diet and physical activity also contribute to the six percent projection, but the absolute increase in Americans who consume ideal diets will remain less than two percent by 2020, if current trends continue.
“Since the 1960s cardiovascular disease death rates have substantially decreased, but if the weight and dysglycemia trends continue to increase, we are in danger of seeing a reversal of those gains,” Huffman said.
Achieving a healthy weight through diet and physical activity is the best way most Americans can improve their cardiovascular health, but, as Huffman stressed, not smoking is the number one preventable cause of preventable death. Yet, one in five Americans still smoke.
Health-e-Solutions comment: Wow! Those ARE some really scary numbers about how many people will have either diabetes or pre-diabetes in about 8 years – staggering in terms of health care costs and quality of life.
The diabetic-alkaline lifestyle can help those who implement it be among the 2 percent who will consume ideal diets by 2020, including those with type 1 diabetes looking for a more natural approach to treating and managing their diabetes. We have products and service all designed to help you implement and sustain dietary changes that get you into the 2 percent club!
