description Introduction: The Mapuche is the more represented ethnic group (87%) among the Chilean indigenous population. However, the research examining body composition in aboriginal groups is scarce. Aim: To determine differences in anthropometric and body fractionation between indigenous (Mapuche) and non-indigenous students from Chile. Methods: The sample included 109 indigenous students and 122 non-indigenous male students. The body fractionation was estimated through the protocol described by the International Society for the advancement of Kinanthropometry (ISAK). One-way analysis of variance (ANOVA) was used to estimate statistical significance of differences among variables. Results: The Mapuche children exhibited lower values of body weight (p<0,001), height (p<0,01) and all the skinfolds, body perimeters and bone diameters assessed compared to non-Mapuche, excepting for the forearm circumference (p<0,05) and transverse thorax diameter (p<0,05). Regarding body composition, the indigenous students showed lower values of fat mass (p<0,001), residual mass (p<0,05) and epithelial mass (p<0,001). However, they achieve higher percentages for muscle mass (p<0,01) and bone mass (p<0,01) than the non-indigenous students. Conclusion: The Mapuche students show better muscle and bone mass scores, while showing lower percentages of fat and residual epithelial mass with respect to non-Mapuche students from the same area of residence.   RESUMO  Diferenças no fracionamento corporal entre escolares chilenos indígenas e não-indígenas Introdução: Os mapuche é o grupo étnico mais representado (87%) na população indígena chilena. Entretanto, a pesquisa que examina a composição corporal em grupos aborígenes é escassa. Objetivo: Determinar as diferenças no fracionamento antropométrico e corporal entre estudantes mapuche e não-mapuche do Chile. Métodos: Foram incluídos 109 alunos mapuche e 122 estudantes não-mapuche. O fracionamento corporal foi estimado através do protocolo descrito pela Sociedade Internacional para o Avanço da Kinanthropometry (ISAK). A análise de variância unidirecional (ANOVA) foi utilizada para estimar a significância estatística das diferenças entre as variáveis. Resultados: As crianças mapuche apresentaram menores valores de peso corporal (p <0,001), altura (p <0,01) e todas as dobras cutâneas, perímetros corporais e diâmetros ósseos avaliados em relação aos não-mapuche, exceto para a circunferência do antebraço (p < 0,05) e o diâmetro transversal do tórax (p <0,05). Quanto à composição corporal, os alunos Mapuche apresentaram menores valores da massa gorda (p <0,001), massa residual (p <0,05) e massa epitelial (p <0,001). Contudo, obtêm maiores percentuais de massa muscular (p <0,01) e massa óssea (p <0,01) do que os não-mapuche. Conclusão: Os estudantes mapuche apresentaram melhores escores de massa muscular e óssea, apresentando menores porcentagens de gordura e massa epitelial residual em relação a estudantes não-mapuches da mesma área de residência.
