Changing sodium intake in children. The Minneapolis Children's Blood Pressure Study
Abstract:
To assess the effects of modifying dietary sodium intake, 80 school children with blood pressures above the 95th percentile for age and sex but below 130/90 mm Hg at school screening were randomized to a family intervention program or a control group. Twenty children aged 6 to 9 years and their families began a program to modify the family diet toward a goal of 70 mEq sodium per person per day. Adherence was assessed by 3-day food records and urine collections in children and adults. The sodium intakes and blood pressures of the intervention and control group were compared 1 year after randomization. Sodium intake was significantly lower in the intervention group only in the active participants as compared to dropouts and controls (87 vs 130 and 133 mmoles/24 hr). There were no significant differences between the groups in height, weight, or blood pressure.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
Factors affecting Blood pressure
Physiological Factors:
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
