To determine the prevalence of undernutrition in children with cerebral palsy and to compare subjective and objective methods of nutritional assessment.
This was a hospital based analytical observational study in which 180 children of cerebral palsy, aged 1–12 y, attending tertiary level hospital, Jaipur from March, 2012 through March, 2013 were included. Subjective assessment was done by questionnaire (Subjective Global Nutritional Assessment; SGNA) in which questions related to nutrition history and physical examination, signs of fat, muscle wasting and edema was done while objective assessment was done by weight, height and triceps skinfold thickness (TSFT) measurements.
In this study prevalence of undernutrition by subjective method (SGNA) was 76.67% while by objective measurement (weight, height, TSFT) was 48.89%, 77.78% 35.18% respectively. There was fair to moderate agreement between the SGNA and objective assessments including weight and height (k = 0.341, p = 0.000; k = 0.337, p = 0.000 respectively) while for TSFT agreement between both methods was poor (k = 0.092, p = 0.190). In the index study, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of SGNA was for weight was 95%, 37%, 56%, 90%; for height 84%, 50%, 85%, 47%; for TSFT 81%, 30%, 38%, 75% respectively.
The prevalence of undernutrition is high in cerebral palsy children. SGNA can be a reliable tool for assessing nutritional status in children with cerebral palsy and is a simple, comprehensive, noninvasive, and cost-effective tool for screening undernutrition in children of cerebral palsy.
