The Psychomotor and Nutritional Development of Severe Marasmic Infants in Nutritional Recovery Centers

Seventy infants with early and severe marasmic undernutrition were examined in a follow-up study after a treatment period in Nutrition Recovery Centers.Their psychomotor development was analyzed using an evaluation scale of psychomotor development standardized in Chile. The mean age of admission to the Nutritional Recovery Centers was 228 ± 1–4 days, and the length of hospitalization was 148 ± 41 days. On admission, the developmental quotient is 0.57 ± 0.17, indicating very severe psychomotor retardation of these infants. At discharge, this quotient is 0.77 ± 0.15, an increase that is statistically significant (P < 0.01). Analyzing the correlation between weight recovery and psychomotor development, there is an r = 0.18 (N.S.) for infants under 6 months of age and r = 0.14 (N.S.) for children over 6 months of age. Regarding nutritional recovery, on admission the average weight deficit was −3.98 SD (40% weight deficit) which is reduced to −1.93 SD at departure (20% weight deficit). This increase in weight is significant at P < 0.01.
