Mild Increase in Daily Sodium Increases Risk of Hypertension Interview with:
Tomonori Sugiura, MD, PhD
Department of Cardio‐Renal Medicine and Hypertension
Nagoya City University Graduate School of Medical Sciences
Nagoya  Japan

Medical Research: What is the background for this study? What are the main findings?

Dr. Sugiura: Although there is a close relationship between dietary sodium and hypertension, the concept that individuals with relatively high dietary sodium are at increased risk of developing hypertension compared to those with relatively low dietary sodium, has not been intensively studied in a cohort. Therefore, the present observational study was designed to investigate whether individual levels of dietary sodium critically affect future increases in blood pressure in the general population.

The main findings of this study were that a relatively high level of dietary sodium intake and also a gradual increase in dietary sodium, estimated by urinary sodium excretion, are associated with a future increase in blood pressure and the incidence of hypertension in the general population.

Medical Research: What should clinicians and patients take away from your report?

Dr. Sugiura: A mild increase in sodium intake within the range observed in usual daily life, but not a drastic sodium load as observed in interventional studies, increases the chance of developing hypertension.

Medical Research: What recommendations do you have for future research as a result of this study?

Dr. Sugiura: As a result of this study, we strongly suggests that appropriate methods of effective education need to be developed to reduce dietary sodium intake in hypertensive patients, as well as the general population.
