Being Obese for a Decade Increases Heart Disease Risk

Being obese for a decade increases heart disease risk, finds a study. New research suggests that the number of years spent carrying overweight raises distinct risk factor for heart problems later in life.


The study, published in the journal Clinical Chemistry shows that a person who spends being obese for every 10 years the future risk of having a high level of troponin which can cause heart damage raised 1.25 times.

Troponins are found in skeletal and heart (cardiac) muscle fibers that produce muscular contraction. It is a protein that’s released into the bloodstream during a heart attack. Therefore, to keep the heart healthy and minimize damage, it is important to maintain a healthy weight throughout the lifespan.

For the study, a team from Johns Hopkins University examined 9,062 participants and followed them between 1987 and 1998. Team four times analyzed the participants during the study. It assessed participants’ body mass index (BMI), history of heart disease, and levels of troponin. It also measured their weight during the study and asked them to report their weight at age 25 to track their BMI from young adulthood through late middle age and elderly years.

The team found that those who increased their BMI to the overweight or obesity range at the fourth analysis increased troponin levels of at least 14 nanograms per liter at 1.5 times which indicated heart damage.

“The study suggests that even in the absence of such heart disease risk factors as high blood pressure, diabetes or kidney disease, the number of years spent obese or overweight contributes to the higher likelihood of heart damage,” said Chiadi Ndumele, Assistant Professor at the Johns Hopkins University. Ndumele says that being obese for a decade increases heart disease risk.
