Overweight men and women (with a body mass index of 25 or more, an indicator of overweight) participated in the study. A total of 623 were aged 30 – 49 (the younger group), and 605 were age 50 – 65 (the older group). The researchers found that in individuals who lost 6,8kg, or more, over a four-year period, the long-term risk of high blood pressure was reduced by 28% in the younger group and by 37% in the older group.
Even more modest weight loss lowered the chances of high blood pressure, provided that the losses were sustained for an additional four years. Individuals in the younger group, who lost at least 2kg and kept it off for the next four years, had a 22% decline in the risk of high blood pressure, while a 26% decrease occurred in the older patients.
