Energy balance

Arm girth alone does not independently cause elevated blood pressure; the association between large arms and high blood pressure is mediated by general adiposity (relative weight).

Having large arms does not cause high blood pressure. However, large arms are often a sign of overall higher body fat, which does raise blood pressure. Focus on overall weight management rather than worrying about arm size affecting your blood pressure reading.

GoodRefutesHIGH confidence
Arm girth produces no independent effect on blood pressure. Blood pressure and the rate of development of hypertension were distinctly related to relative weight and changes in weight under observation but not to upper arm girth independent of weight.
