Fatty tissue accumulated in the neck linked to heart problems, study finds

The ACTIBATE project

The study carried out at the UGR is part of the ACTIBATE project (Activating Brown Adipose Tissue through Exercise--see http://profith.ugr.es/actibate). The project is financed by the Spanish Ministry of Economy and Competitiveness and the Health Research Fund of the Carlos III Health Institute (PI13/01393). The research was led by Jonatan Ruiz Ruiz and its results have been published in the International Journal of Obesity.

The study shows that the accumulation of fat in the neck--measured with computed tomography scanning--as well as its distribution in different compartments, is associated with greater overall and central adiposity, greater cardiometabolic risk, and a greater inflammatory status among healthy young adults, regardless of the amount of total and visceral fat. In addition, among the most relevant findings, it was observed that this accumulation of fat in the neck was as powerful a factor (in terms of direction and magnitude) as the accumulation of visceral fat in the prediction of cardiometabolic risk and inflammatory status, especially in men.

"Therefore, these results underline the need for further research in this new direction, to better understand the effect of fat accumulation in the upper part of the trunk (including the neck) and its clinical repercussions, especially in cardiometabolic risk and inflammation," explains Francisco Miguel Acosta Manzano, also among the main authors of the research.

"We still have much work to do. We need to investigate the adipose tissue of the neck in greater depth, to understand its pathogenic role in obesity and associated comorbidities, as well as its biological importance. Furthermore, we only have scant knowledge about the morphological or molecular characteristics of the adipocytes in these deposits, and here basic studies are required. As we increase our knowledge of this deposit, we can also determine whether specific interventions (for example, physical exercise and/or restricted calorie intake) could help reduce the accumulation of fat in the neck (as well as total fat) and implement them clinically," explain Arias Téllez and Francisco Miguel Acosta Manzano, both PhDs students on the Biomedicine programme of the UGR's International School for Postgraduate Studies and members of the PROFITH-CTS977 Research group (http://profith.ugr.es).
