Curvas de velocidade da altura e os parâmetros do salto pubertário de crianças e adolescentes Caririenses

Abstract

Apresentamos as curvas médias da distância e velocidade da altura, as idades em que ocorreram os parâmetros do salto pubertário e comparamos os valores obtidos com referências nacionais e internacionais. A amostra contém 280 crianças e adolescentes dos dois sexos que participaram do Projeto Crescer com Saúde no Cariri. Foi utilizado o modelo logístico triplo implementado no software AUXAL. As idades no take-off ocorreram aos 8.8 e 10.3 anos, a altura alcançada foi de 127.3 e 134.0 cm e a velocidade foi de 4.7 cm/ano para ambos os sexos. O pico de velocidade da altura (PVA) ocorreu aos 11.6 anos nas meninas e aos 13.6 anos nos meninos. A altura média alcançada foi de 143.5 e 154.8 cm com uma velocidade de 7.1 e 8.7 cm/ano entre meninas e meninos, respectivamente. As curvas de crescimento da altura das crianças do Cariri mostram um padrão semelhante ao observado em outros estudos. Apesar da defasagem temporal entre o presente estudo e os demais utilizados nas comparações, as idades de ocorrência do PVA, bem como os valores encontrados nos parâmetros do salto pubertário são semelhantes.

“…46 Furthermore, PHV was 7.1cm/year in boys and 6.6cm/year in girls. Even though this value for children is consistent with that found in international studies where a PHV between 7.3cm/year and 10.4cm/year is reported (i.e., 7.3cm/year in Japan, 41 8.17cm/year in Portugal, 36 8.49cm/year in Brazil, 36 9.92cm/year in Canada, 36 9.79cm/year in England, 39 and 10.4cm/year in Canada 42 ), it is lower in girls, as the values reported for this population worldwide vary between 7.1cm/year and 9.0cm/year (i.e., 8.1cm/year in England, 40 8.6cm/year in Canada, 42 and 9.02cm/year in Japan). 47 Considering the foregoing, it can be stated that the APHV and PHV of children and adolescents in Huila are lower (earlier maturation) than the APHV and PHV described in most of the previously mentioned international studies.…”

“…15 In relation to what has been described in international studies, the APHV of children in Huila (12.9 years) is found to be: (i) between 0.8 and 1.4 years below that reported for this population in the United States (13.8 and 13.70 years), 34,35 Canada (13.9 years), 36 India (14.3 years), 37 Switzerland (13.9 years), 38 England (14.12 and 13.91 years), 39,40 and Brazil (13.9 years); 41 (ii) between 0.1 and 0.5 years below that reported in Canadian (13.4 years), 42,43 Brazilian (13.4 years), 36 Portuguese (13.0 and 13.4 years), 43,44 and Japanese (13.0 years) children; 45 and (iii) between 0.4 and 0.7 years above that reported in Brazilian (12.5 years) 46 and Japanese (12.2 years) children. 47 In the case of girls, APVH (10.5 years) is found to be: (i) between 1.5 and 2.0 years below that reported for this population in the United States (12.5 years), 34 India (12.4 years), 37 Switzerland (12.2 years), 48 and England (11.99 years); 39 (ii) between 0.7 and 1.4 years below that reported for girls in England (12 years), 40 Canada (11.8 and 11.7 years), 42,43 United States (11.6 years), 35 Japan (11.2 years), 45 Brazil (11.6 years), 41 and Poland (11.9 years); 9 (iii) 0.2 years above that of Japanese girls (10.3 years); 47 and (iv) similar to that reported for Brazilian girls (10.5 years). 46 Furthermore, PHV was 7.1cm/year in boys and 6.6cm/year in girls.…”
