Location of body fat can increase hypertension risk

02.09.2014

Abdominal fat more strongly associated with high blood pressure risk than overall obesity

People with fat around their abdominal area are at greater risk of developing hypertension when compared to those with similar body mass index but fat concentrations elsewhere on the body, according to a study published today in the Journal of the American College of Cardiology.

Obesity is a known risk factor for hypertension, or high blood pressure, and it is widely reported that the location of fat on a person's body can lead to increased risk of other health issues like heart disease and cancer. However, the relationship between hypertension and overall obesity versus site-specific fat accumulation is unclear.

For this study, 903 patients enrolled in the Dallas Heart Study were followed for an average of seven years to track development of hypertension. Hypertension was classified as a systolic blood pressure of greater or equal to 140, diastolic blood pressure of greater or equal to 90, or initiation of blood pressure medications. Patients also received imaging of visceral fat, or fat located deep in the abdominal cavity between the organs; subcutaneous fat, or visible fat located all over the body; and lower-body fat.

"Generally speaking, visceral fat stores correlate with the 'apple shape' as opposed to the 'pear shape,' so having centrally located fat when you look in the mirror tends to correlate with higher levels of fat inside the abdomen," said senior author Aslan T. Turer, M.D., M.H.S., a cardiologist at the University of Texas Southwestern Medical Center in Dallas.

At the end of the study period, 25 percent of patients developed hypertension. While higher BMI was associated with increased incidence of hypertension, when abdominal fat content, overall fat content and lower-body fat content were factored in, only abdominal fat remained independently associated with hypertension. The relationship between abdominal fat and hypertension did not change when factoring in gender, age or race.

The strongest correlation between abdominal fat and hypertension was observed with retroperitoneal fat, which is a type of visceral fat located behind the abdominal cavity and largely around the kidneys.

"The high incidence of hypertension and presence of retroperiotoneal fat could suggest that the effects from fat around the kidneys are influencing the development of hypertension," Turer said. "This link could open new avenues for the prevention and management of hypertension. The finding of the fat around the kidney is a novel one and we do not know specifically what the 'in the mirror' correlates are."

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
