title: [Etiology of growth retardation in children of adolescent mothers].
abstract: The influence of some nutritional and hormonal factors in the growth failure detected in children of teenage mothers belonging to medium-low socioeconomic level (SEL) was studied. They were compared with children of mothers older than twenty years of the name SEL. Only growth retarded children of teenage mothers had significant delay in bone age, compared with chronological age (14.8 +/- 4.1 vs 18.2 +/- 2.2 months respectively). Children with growth failure had significantly lower plasma Zn (85.7 +/- 13.3 vs 94.6 +/- 17.9 micrograms/dl), Cu (106.2 +/- 32.5 vs 122.0 +/- 13.8 micrograms/dl) and hemoglobin (Hb) (11.7 +/- 2.1 vs 12.8 +/- 2.1 micrograms/dl) levels. No differences in plasmatic levels of thyrotropin, thyroid hormones and response of growth hormone to L-Dopa stimulation were detected in comparison with those of children with normal stature. We concluded that etiological factors of growth failure were similar in children of teenage and adult mothers according to the parameters analyzed. The increased prevalence of growth failure in children of teenage mothers may be due to a greater impact of the analyzed factors.
