The increase of weight of 238 hypotrophic and 31 eutrophic newborns is analyzed and assigned to 4 clusters in the course of their first 21 months. It is compared with body weight curves by Prader. Cluster 1 Increase in weight about the 50th percentile Cluster 2 Increase in weight between the 50th and 3rd percentile Cluster 3 Increase in weight just below the 3rd percentile Cluster 4 Increase in weight clearly below the 3rd percentile More than a half of all hypotrophic newborns had a body weight below the 3rd percentile by Prader (cluster 3 and 4) on attaining the age of 21 months. The appearance of hypotrophy in the newborns is subdivided into 4 groups by means of gestational age and relative birthweight: Group 1 eutrophic and moderate hypotrophic (n = 77) Group 2 premature and moderate hypotrophic (n = 46) Group 3 eutrophic and distinct hypotrophic (n = 62) Group 4 premature and distinct hypotrophic (n = 53) We found that the increase of weight correspond to cluster 4 in 4% of group 1, in 22% of group 2, in 32% of group 3, and in 43% of group 4. At last the increase of body weight is hard influenced in the first 3 years of life by hypotrophy and degrees of maturity of the newborns.
