If you have high body mass index (BMI), then there would more chances that you have increased blood pressure (BP) too, a new study has found.
The findings have published in the journal JAMA Network Open and showed a strong relationship between obesity and high blood pressure.
Sometimes, uncontrolled high blood pressure can lead to several cardiovascular diseases such as heart attack, stroke and heart failure.
This study has involved 1.7 million Chinese men and women aged between 35 and 80 years and recorded the participants’ blood pressure.
They observed an increase of 0.8 to 1.7 mm Hg (kg/m2) in blood pressure per additional unit of BMI in individuals who were not having anti-hypertensive medication.
The population had an average BMI of 24.7 and a mean systolic blood pressure of 136.5, which qualifies as stage-I hypertension, according to American Heart Association guidelines.
“If trends in overweight and obesity continue in China, the implication of our study is that hypertension, already a major risk factor, is likely to become even more important,” said senior author Harlan Krumholz from Yale University in the US.
“This paper is ringing the bell that the time is now to focus on these risk factors,” he added.
“The enormous size of the dataset allows us to characterise this relationship between BMI and blood pressure across tens of thousands of subgroups, which simply would not be possible in a smaller study.
