Abstract:
With advancing age, the human being is subject to physiological changes. They contribute to reduce the sensitivity to primary tastes, especially, the salt. The elderly tends to increase salt intake in order to adjust it to taste. Thus, the amounts of sodium (Na) increase the risk of high blood pressure (BP). This situation associated with a high level of Body Mass Index (BMI), is a major risk for cardiovascular disease (CVD), a major cause of death.
This study aimed to compare the intake and excretion of Na in institutionalized elderly taking into account the CVD risk, BMI and BP. Factors such as age, gender and food obtained outside the institution were, also, considered. The study involved a sample of 40 elders, which was held an interview with a rec24h to quantify Na consumed. Quantification of Na excretion was determined by quantitative clinical analysis 24 hours urine. Most elders had more than 85 years old and presented CVD risk (85%), were female (65%), were overweight (77.5%), had normal BP (65%), had food obtained outside the institution (57.5%) and did not have the habit of adding salt to food (100%). It was found that ingestion of Na was higher in the elderly at CVD risk and with high BMI. About intake of Na, it was found that other factors considered were not differentiating factors. When compared Na excretion considering all factors, it was found no differences statistically significant.
