Estrés y obesidad

People who suffer long-term stress may be more prone to obesity, according to research by scientists at UCL which involved examining hair samples for levels of cortisol, a hormone which regulates the body’s response to stress.

Chronic stress has long been hypothesised to be implicated in obesity — people tend to report overeating and ‘comfort eating’ foods high in fat, sugar and calories in times of stress, and the stress hormone cortisol plays an important role in metabolism and determining where fat is stored.

Previous studies looking at the link between cortisol and obesity relied mainly on measurements of the hormone in blood, saliva or urine which may vary according to the time of day and other situational factors. These studies failed to capture long-term cortisol levels.

This research involved 2,527 men and women aged 54 and older taking part in the English Longitudinal Study of Ageing, taking data over a four-year period.

They found that people who had higher levels of cortisol present in their hair tended to have larger waist circumference measurements, were heavier, and had a higher body mass index (BMI). Individuals classified as obese on the basis of their BMI (greater than or equal to 30) or waist circumference (greater than or equal to 102cm in men, 88cm in women) had particularly high levels of hair cortisol.

More research is needed and if causation is proved, then targeting cortisol levels may offer a new method for treating obesity.
