Urinary metabolites and nutritional status of Egyptian elderly

ABSTRACT

The nutritional status of 61 healthy Egyptian elderly aged 60-85 years were assessed. Observations were assessed. The observation showed that 39.47% of the females were hypertensive which were less in males, where diastolic blood pressure was above 95 mmHg. Prevalence of obesity was higher in females than in males. Mean volume of 24 hours urine and the mean urinary excretions were investigated, showing that the mean volume of urine and hydroxyproline excretion were lower at older age with significant difference [P <0.05]. Potassium, calcium and magnesium excretion were also lower, but the difference did not reach significant level [P <0.05]. The correlation between blood pressure, body mass index [BMI] and 24 hours urine excretions was studied. Several indicators of the nutritional status showed differences among age groups, and few of these differences being due to physiological aging
