The effect of early childhood nutritional supplementation on skeletal maturation at adolescence was investigated in 663 rural Guatemalans, aged 11-18 y. Skeletal maturation was assessed by the Tanner-Whitehouse-2 method.
The subjects were former participants in the Institute of Nutrition of Central America and Panama longitudinal study of growth and development (1969-77) residing in four villages (two large and two small) in eastern Guatemala.
The villages were randomized within pairs to receive either a high energy, high protein supplement (Atole) or a low energy supplement with no protein (Fresco).
Skeletal maturity was observed across all villages to be delayed signiflcantly relative to a British reference for boys<14 y of age, but not for older boys or for girls<14 y of age.
Delays in girls>14 years could not be determined reliably because many had reached maturity.
Girls<14 years from Atole villages were more advanced in skeletal maturity than similar age girls from Fresco villages but these differences were found only in comparisons of the large villages.
The relationship between early nutrition and biological maturation at adolescence may be obscured in this sample by the advanced age at which the subjects were examined in adolescence.
