Abstract
The relationship between blood pressure and sodium intake by hypertensive obese individuals was examined on 18 subjects with the diet of “Four Food Group Diet” (energy 960-1200 Cal, protein 64.0g) for 12 weeks.
The adherence to the diet what checked by personal everyday food record. Blood pressure, body weight and urinary sodinm excretion were determined. The blood pressure was lowered from 158±11mmHg to 128±15mmHg (systolic) and from 100±10mmHg to 80±12mmHg (diastolic). The sodium excretion was decreased from 14.4±5.1g to 6.8±2.7g.
The body weight was dropped from 70.0±12.0kg to 62.2±9.1kg. No correlation was observed between the change of blood pressure and that of body weight or temperature, except change of urinary sodium excretion.
It was concluded that reduction of blood pressure depends on the extent of reduced sodium intake on this diet. Calculated salt intake was compared with sodium excretion, and at the beginning of the experiment the former was higher than the latter, but after therapy the ratio of both value became 0.95. “Four Food Group Diet” management is the useful for the longterm control of the hypertensive obese patients.
