[Bioelectric impedance in the nutritional evaluation of mentally deficient quadriplegic adults].
Severely mentally retarded persons with cerebral palsy show a high rate of acute and chronic malnutrition. Without discarging other factors which might be at play, caloric intake deficiency stemming from the difficulties involved in being fed appear to play a crucial role in its etiology. In the assessment of these disorders, anthropometry is limited by the lack of adequate reference values and by the difficulty or impossibility of measuring height using the conventional method. The purpose of this study is to see how changes in body composition brought about by an increase in dietary caloric intake are perceived by both anthropometry and biolectrical impedance analysis. To do so, 13 subjects were selected from a group of 203 severely mentally retarded persons made up of 25% cerebral palsy patients and 13% quadriplegics. The 13 subjects were fed orally without tubes and all had tricipital skinfolds of less than P25. All 13 were given a 25% caloric increase over the regular diets for a period of two months. This increase was provided by means of a polymeric, normoproteic, hypercaloric preparation. Weight and brachial perimeter showed significant increases coinciding with the administration of the supplement. Theses increases were not noticeable two months after discontinuing the supplement. There were no significant changes in tricipital and subescapular skinfolds, muscular circumference of de mid-arm, resistance, reactance, or the total body an extracellular water calculated from the latter two values. From these results we deduce that biolectrical impedance analisys offers no advantages over anthropometry in monitoring the nutritional status of quadriplegics.
