A new study published today could reduce the prevalence of obesity and prevent up to half of new cases of type 2 diabetes in the United States. Journal of the American Heart Association, American Heart Association open access journal. Obesity is a major cause of diabetes, and new studies suggest that more coordinated efforts are needed to reduce the incidence of obesity-related diabetes.

According to the US Centers for Disease Control and Prevention, type 2 diabetes is the most common form of diabetes, affecting more than 31 million Americans. Risk factors for type 2 diabetes include overweight and obesity. Must be 45 years or older. I have a close relative who has been diagnosed with type 2 diabetes. Physical activity less than 3 times a week; or a history of gestational diabetes (diabetes during pregnancy). Type 2 diabetes is more common among blacks, Hispanics or Latinos, Native Americans, Alaska Natives, Pacific Islands or Asian Americans.

The number of deaths from type 2 diabetes in people under the age of 65 is increasing with serious complications such as disconnection and hospitalization. In addition, type 2 diabetes affects the risk of heart disease and stroke. Adults with type 2 diabetes are twice as likely to have a heart attack or stroke as people without diabetes.

Type 2 diabetes can be prevented or delayed by healthy lifestyle changes such as losing weight, eating a healthy diet, and exercising. Behavioral changes have been shown to help people with pre-diabetes lose 5% to 7% of their body weight and reduce their risk of developing type 2 diabetes by 58% (age 60), according to the National Diabetes Prevention Program. 71% of the above people). Researchers investigated the prevalence and excess risk of obesity-related type 2 diabetes.

“Our study highlights the potential impact of obesity reduction on the prevention of type 2 diabetes in the United States. Obesity reduction should be prioritized. Access to nutritious foods Increasing, Promoting Physical Activity, Public Health Initiatives to Support a Healthy Lifestyle By developing a community program to prevent obesity, we can significantly reduce new cases of type 2 diabetes. ” Said Dr. Natalie A. Cameron, lead author of the study, a resident doctor in internal medicine at the McGo Medical Center at Northwestern University in Chicago.

Researchers used information from four pooled cycles (2001-2016) of the Atherosclerosis Multiethnic Study (MESA) and the National Health and Nutrition Examination Survey (NHANES). MESA is a continuous longitudinal study of 45-84 years old who did not have cardiovascular disease at the time of recruitment. The MESA data included in this study were collected during five visits from 2000 to 2017 at six centers across the United States. NHANES is a biennial cross-sectional study of the US population using patient questionnaires and laboratory data.

In this analysis, the author limited the data to participants aged 45-79 years. They included only non-Hispanic whites, non-Hispanic blacks, or Mexican-Americans who did not have type 1 or type 2 diabetes at the start of the study. Researchers have calculated both the prevalence of obesity and the excess risk of obesity-related type 2 diabetes.

The results of this survey are as follows:

  • Among NHANES participants, the overall prevalence of obesity increased from 34% to 41%, consistently high among adults with type 2 diabetes.
  • Among MESA participants
    • One in ten (11.6%) developed type 2 diabetes 9 years later.
    • Obese people were almost three times more likely to develop type 2 diabetes than non-obese people (20% vs. 7.3%, respectively).
  • In both the MESA and NHANES groups:
    • Obesity was associated with the development of type 2 diabetes in 30-53% of cases.
    • The majority of obese participants had an annual household income of less than $ 50,000 and were likely to be non-Hispanic blacks or Mexican-Americans.
    • The prevalence of obesity was the lowest among non-Hispanic Caucasian women, but this group had the highest obesity-related type 2 diabetes.

“Our study found that non-Hispanic black adults and Mexican-American adults have a higher prevalence of obesity than non-Hispanic white adults. These differences are , May indicate an important social determinant of health that contributes to new cases of type 2. Obesity plus diabetes, “says Cameron.

“In addition, the obesity epidemic clashed with the COVID-19 epidemic,” said Sadiya S. Khan, MD, M., lead author of the study and assistant professor of medicine and preventive medicine at Northwestern University’s Fineberg School of Medicine. .Sc. Says. “The severity of COVID-19 infection in obese people is of concern due to the increased burden of adverse health effects that may be experienced in the coming years. Therefore, more adults are more likely. Further efforts are needed to adopt a healthy lifestyle and reduce prevalence. Obesity. “

Results may not be generalized to the entire US population, as the analysis included only non-Hispanic whites, non-Hispanic blacks, or Mexican-American middle-aged to elderly people without cardiovascular disease. There is sex. Future studies are needed to assess the burden of obesity on new cases of type 2 diabetes in other age groups and racial and ethnic groups.


The prevalence of diabetes depends on race and ethnicity
