HEALTH UPDATE: obesity link to high blood pressure has weakened

It seems that the association between body mass index (BMI) and high blood pressure or hypertension has decreased since 1989, researchers say. The finding suggests that obesity may not have as much of an impact on heart-related disease as previously thought.
"High blood pressure is a leading cause of the global burden of disease," Dr Pascal Bovet, of the University of Lausanne, Switzerland, and colleagues write in the medical journal Epidemiology. "The prevalence of hypertension, and of several other conditions (including diabetes), is considered to be linked to the world-wide epidemic of obesity."
