Race and Ethnicity Play Significant Role in Determining Accumulation of Fat Around the Heart

Researchers at University of Pittsburgh Graduate School of Public Health have found that a person’s race and ethnicity plays a significant role in the likelihood of the accumulation of fat around his heart, which is an indicator of heart disease.

The findings, published online today in the International Journal of Obesity, indicate that it may be useful to take racial and ethnic differences into account when designing programs to reduce obesity because what works for one man might not be as beneficial for another. This analysis was funded in part by the National Institutes of Health (NIH).

Heart Attack - Overview
Heart attack is the death of the heart muscle due to loss of blood supply. Heart disease is the leading cause of death in the United States. Other names for heart attack include acute myocardial infarction, coronary thrombosis, and coronary occlusion.

"If you are an African American man and carry excess weight mainly around the mid-section, then you have a higher likelihood of more fat around the heart than if you gain weight fairly evenly throughout your body," said lead author Samar R. El Khoudary, Ph.D., M.P.H., assistant professor in Pitt Public Health's Department of Epidemiology.

"But the reverse is true for Koreans – their heart disease risk is greater with overall weight gain. Knowing this can help doctors specify the right physical training for each racial ethnic group to reduce their heart disease risk."

Dr. El Khoudary's analysis relied on data from the "Electron-Beam Tomography, Risk Factor Assessment Among Japanese and U.S. Men in the Post-World War II Birth Cohort Study," also known as the ERA JUMP study. It is a population-based study of men enrolled between 2002 and 2006 who were ages 40 to 49 and free of cardiovascular disease, type-1 diabetes and other severe diseases at the time of enrollment.

Heart attack is the death of the heart muscle due to loss of blood supply. Simple guidelines to avoid heart attack are listed.

The recent analysis took a closer look at 1,199 men in the study who were white or black from Allegheny County, Japanese-American from Hawaii, Japanese or Korean.

The study looked at the amount of fat around the heart called ectopic cardiovascular fat. Higher volumes of this fat are associated with greater risk of heart disease.

Tips to Prevent Heart Attacks
Heart Attack occurs when the flow of oxygenated blood to heart muscles is hindered or stopped due to built-up of plaques in coronary arteries. Heart Attack is the No.1 killer among Indians.

For white men, an increase in body mass index, or BMI, which is a measure of overall body fat, and abdominal fat are equally likely to indicate an increase in fat around the heart.Compared to white men:

• Black men who carry disproportionally more weight around their mid-section are at similar risk of having more fat around their hearts. Increases in BMI have lower impact.

Air travel is for everyone, even those with medical conditions.

• Japanese and Japanese American men are also at similar risk of having more fat around their hearts if they have more fat in their abdomens, with BMI having less of an impact.

• Korean men with higher BMIs have a higher likelihood of fat around the heart, whereas abdominal fat matters less.

"What we now need to determine is whether concentrating efforts to reduce overall body fat or fat in the abdomen will actually decrease fat around the heart more in people of certain racial or ethnic groups," said Dr. El Khoudary.

"Such a long-term evaluation could help in designing race-specific heart disease prevention strategies."
