People who are overweight or obese may experience cardiovascular disease at an earlier age and live longer burdened by the disease.
Highlights
- Lifetime risks for developing cardiovascular disease were higher in overweight and obese adults.
- People who are overweight or obese may experience cardiovascular disease at an earlier age and live longer burdened by the disease.
"We wanted to focus on both the risk of cardiovascular events and implications in terms of healthy longevity - living without cardiovascular disease - by weight status," said Sadiya Khan, instructor of medicine at Northwestern University's Feinberg School of Medicine in Chicago, Illinois.
Study Details
For this study, the researchers looked at cardiovascular disease data in 72,490 participants from the LRPP, focusing on middle-aged people (average age 55). Participants were healthy and free of cardiovascular disease when they enrolled in the study. The average BMI was 27.4 for men and 27.1 for women.
During follow up, 13,457 cardiovascular disease events -- a diagnosis of coronary heart disease stroke, and heart failure -- including 6,309 deaths due to cardiovascular disease and 11,782 deaths not associated with cardiovascular disease occurred.
Key Findings
- Both overweight and obese people tended to live slightly shorter or similar lifespans compared to people with normal body weight, whether or not they had cardiovascular diseases.
- Compared to people with normal BMI, lifetime risks for developing cardiovascular disease were higher in overweight and obese adults. For example, middle-aged women who were overweight were 32 percent more likely to develop cardiovascular disease in their lifetime compared to women of normal weight.
- Average years lived without cardiovascular disease were longest for people with normal BMI, while years lived with cardiovascular disease were longest for overweight and obese people.
- Overweight or obese people experienced cardiovascular disease at an earlier age than those with normal BMI. For example, in middle-aged women who were overweight, cardiovascular disease began 1.8 years earlier than normal weight women, and for those who were obese, 4.3 years earlier.
Another limitation of the study is the use of BMI, which indirectly measures body fat and does not consider central obesity, the build-up of abdominal fat that can adversely affect health. Future studies could explore other measures of overweight and obesity, such as waist circumference and abdominal fat.
"Our findings suggest that healthcare providers need to continue to be aware of the increased risk of earlier cardiovascular disease faced by overweight and obese people," Khan said. "Healthcare providers should emphasize the importance of maintaining healthy weight throughout their lives to live longer, healthier lives."
