El estado cognitivo y funcional como factor determinante del déficit nutricional en una población senil en hemodiálisis crónica

Introduction

The largest population group of 65, usually more susceptible to emotional and nutritional effects arising from chronic kidney disease. Currently, there are no studies that establish an association between emotional states, cognitive impairment, with the nutritional status of elderly patients on hemodialysis.

Objective

To determine the correlation of cognitive, functional and emotional state to nutritional status in a population of 64 years on hemodialysis.

Materials and methodmethods

An observational, cross-sectional study; 107 adult patients were analyzed, with chronic kidney disease stage 5 on hemodialysis. We evaluated it been cognitive per test mini-mental state examination (MMSE), emotional state as HADS scale and short -12 Form (SF-12), quality of life by Karnofsky scale and SF-12, assessment of nutritional status by subjective global assessment (VGS), body mass index (BMI) and biochemical parameters.

Results

The mean age was 70.6 ± 5.2 years, with a state of mild malnutrition 29.9%, 65.4% moderately malnourished and 4.7% severely malnourished; an average MMSE score of 20.6 ± 5.2, as mild cognitive impairment, Karnofsky score of 71.4 ± 10.9 representing a slight functional deficit, 29.9% to 18.7% with depression and anxiety; an association between nutritional status and cognitive impairment (r −0401, P<.01), nutritional status and functional status (r −0361, P<.01) was found.

Conclusion

Based on our data it is possible to establish an association of cognitive and functional status with the degree of malnutrition in the elderly population, these constitute an important determinant of nutritional deficit.
