Abstract
The objective of this study was to analyze physical growth and body composition variables of students from German, Italian and Polish ethnic groups resident in the Northwest of Rio Grande do Sul state, Brazil. The sample was composed of 1428 students (696 males and 732 females). The descriptive statistical methods ANOVA, the Tukey test (p≤ 0.05) and the chi-square test (χ2) were used to analyze the data. Differences were observed in the heights of girls aged up to 9 years, with the Polish group being shorter, and, up to 15 years, for both the Polish and German groups, when compared with the group of Italians. In terms of body mass, there were differences up to 14 years (males) and up to 9 years (females), with the Polish schoolchildren having lowest mass. The German schoolchildren had the highest body fat percentage at 12 years (males) while at 15 years (females), the Polish children had higher body fat percentage than the other ethnic groups (p≤ 0.05). The Polish children exhibited inferior lean body mass (p≤ 0.05) at 14 years (males) and at 9 years (females). The prevalence rates of obesity, for males and females respectively, were 11.1% and 16.2% among the German schoolchildren, 6.6% and 19.4% among the Italians and 7.1% and 16.2% among the Polish. In general, few differences were detected between the ethnic groups, either in terms of physical growth or in terms of body composition. The Polish schoolchildren tended to exhibit inferior results to the Germans and Italians.

Resumo Este estudo objetivou analisar variáveis do crescimento físico e da composição corporal em escolares de diferentes grupos étnicos (alemão, italiano e polonês), residentes na região Noroeste do Estado do Rio Grande do Sul, Brasil. A amostra foi constituída de 1428 escolares (696 do sexo masculino e 732 do sexo feminino). Na análise dos dados foi utilizada a estatística descritiva, ANOVA, teste Tukey (p≤ 0,05) e o teste do qui-quadrado (χ2). Na estatura, no sexo feminino aos 9 anos, foram encontradas diferenças (p≤ 0,05) entre as etnias, com valores inferiores para os escolares poloneses e, aos 15 anos, para os poloneses e alemães quando comparados aos italianos. Na massa corporal, ocorreram diferenças aos 14 anos (sexo masculino) e, aos 9 anos (sexo feminino), com valores inferiores para os escolares poloneses. O percentual de gordura foi superior nos escolares alemães, aos 12 anos (sexo masculino) e poloneses aos 15 anos (sexo feminino), quando comparados aos demais grupos étnicos (p≤ 0,05). Na massa corporal magra, os poloneses apresentaram resultados inferiores (p≤ 0,05) aos 14 anos (sexo masculino) e aos 9 anos (sexo feminino). A prevalência de obesidade, respectivamente para o sexo masculino e feminino, foi de 11,1% e 16,2%, nos escolares alemães, 6,6% e 19,4% nos italianos e 7,1% e 16,2% nos poloneses. De modo geral foram constatadas poucas diferenças entre as etnias tanto nas variáveis do crescimento físico quanto na composição corporal. Os escolares poloneses tenderam a apresentar resultados inferiores quando comparados aos alemães e italianos.
