Clothing skews BP measurement by up to 15mmHg

MEASURING blood pressure by putting the cuff over clothing can skew results higher or lower by up to 15mmHg, a study shows.

In findings which underscore the importance of only taking BP on a bare arm, researchers found in a study of 186 individuals that the older the person the more likely clothing was to increase mean BP values.
