Background
Sodium (Na) intake (I) is involved in the development of hypertension (HPT); to reduce NaI is important in the treatment of HPT, but also the increase in renal Na excretion (E) might be a potential preventive and/or therapeutic opportunity. The SPA Project studied blood pressure (BP) in relation to water (H2O) and NaI with the working hypothesis that an increased H2O I can improve renal Na handling.
Methods
339 healthy, non-overweight children (166 girls), 5.7 years old (IQR: 5.3-6.2) were characterized for: BP (using standardized multiple office BP measurement), Na and H2O I (by means of urinary Na and creatinine from 4 samples taken in 4 days). After categorizing subjects as low/high Na I and low/high water I (based on median value), BP was compared.
Results
Among children with higher NaI, those introducing more H2O, showed a significantly (p<0.001) lower BP (both systolic and diastolic) compared to those who drink less (fig.). This difference was not observed among children with lower NaI.
Conclusion
Our findings support the hypothesis that an increased H2O I, reduces BP perhaps by increasing Na renal E. We speculate that this simple, highly acceptable, inexpensive and harmless measure might have a role in preventing and minimizing the epidemics of HPT and related morbidities.
