    Abstract:
    AIM: To evaluate the nutritional status of mentally retarded children in the region of Galicia in north-west Spain, on the basis of anthropometric variables. METHODS: The following variables were determined in a sample of 128 mentally retarded children (81 M, 47 F): birthweight, bodyweight, height/length, head circumference, mid-arm circumference, mid-arm muscle circumference, triceps skinfold thickness, subscapular skinfold thickness, arm area, arm muscle area, arm fat area, arm lean-to-fat ratio, Shukla's nutrition index and Quetelet's body mass index (BMI). A preliminary statistical analysis indicated that most information content could be maintained considering only eight of these variables. A factor analysis of the resulting 8 x 128 (variables by subjects) data matrix was performed, identifying two factors (FA1 and FA2) that together explained 82% of total variance. Taking these factors as indicators of nutritional status, the data were analysed for possible effects of age, gender, socioeconomic and family environment, intelligence quotient (IQ), presence/absence of cerebral palsy, quality of diet, appetite and antiepileptic use. RESULTS: The analysis suggested that most subjects were in the normal nutrition range, but about 33% showed either borderline or definite malnutrition. Mean score on FA2 showed a significant negative correlation with age. Children with cerebral palsy had lower mean scores on both factors, and scores on both factors varied with IQ. Children with definite malnutrition had a significantly lower IQ than those in the normal nutrition range. Mean score on both factors varied with appetite and quality of diet. The mean FAI score of children from inland-rural areas was significantly lower than that of children from coastal or urban areas. Mean FA1 score increased with increasing age of the parents. The prevalence of obesity was 13% when obesity was defined on the basis of Shukla's nutrition index, and 19% when defined on the basis of FA1 score. CONCLUSION: Malnutrition as revealed by anthropometric variables occurs with a high prevalence among mentally retarded children. The prevalence increases with age, increasing IQ deficit and cerebral palsy.
