By a News Reporter-Staff News Editor at Preventive Medicine Week -- Investigators publish new report on Obesity, Fitness and Wellness. According to news reporting originating from Maywood, Illinois, by NewsRx correspondents, research stated, "Habitual levels of dietary sodium and potassium are correlated with age-related increases in blood pressure (BP) and likely have a role in this phenomenon. Although extensive published evidence exists from randomized trials, relatively few large-scale community surveys with multiple 24-h urine collections have been reported."
Our news editors obtained a quote from the research from the Loyola University School of Medicine, "We obtained three 24-h samples from 2704 individuals from Nigeria, Jamaica and the United States to evaluate patterns of intake and within-person relationships with BP. The average (??s.d.) age and weight of the participants across all the three sites were 39.9??8.6 years and 76.1??21.2?kg, respectively, and 55% of the total participants were females. Sodium excretion increased across the East-West gradient (for example, 123.9??54.6, 134.1??48.8, 176.6??71.0 (??s.d.) mmol, Nigeria, Jamaica and US, respectively), whereas potassium was essentially unchanged (for example, 46.3??22.9, 40.7??16.1, 44.7??16.4 (??s.d.) mmol, respectively). In multivariate analyses both sodium (positively) and potassium (negatively) were strongly correlated with BP (p <0.001); quantitatively the association was stronger, and more consistent in each site individually, for potassium. The within-population day-to-day variation was also greater for sodium than for potassium. Among each population group, a significant correlation was observed between sodium and urine volume, supporting the prior finding of sodium as a determinant of fluid intake in free-living individuals."
According to the news editors, the research concluded: "These data confirm the consistency with the possible role of dietary electrolytes as hypertension risk factors, reinforcing the relevance of potassium in these populations."
