A study was conducted to investigate and compare the nutritional status and physical work performance of children of Brazilian migrant agricultural workers with Brazilian children from wel1-to-do backgrounds. The relationship between nutritional status and physical work performance was also investigated. Dietary analysis was conducted using the 24-hour diet recall method. Evidence was found that intakes of energy, calcium, thiamin, riboflavin, niacin, and vitamin C may have been inadequate among migrant worker children. Their diet was generally monotonous and consisted mainly of rice, beans, and coffee with sugar. Diets of well-to-do children were considerably more varied with good representation from all major food groups. Anthropometric assessment indicated that migrant worker children had values for weight and triceps skinfold thickness that were low compared to American standards. Values for height, arm circumference, and arm muscle circumference were average compared to American standards. Well-to-do children exceeded American standards for all anthropometric parameters measured. Biochemical investigations of protein and iron status were also conducted. Serum total protein and albumin levels were normal in most subjects in both groups. However, many migrant worker, children had low values for hematocrit, serum iron, and transferrin saturation. Most well-to-do children had normal values for these parameters. Hemoglobin levels were adequate in most subjects. Physical work performance was found to be impaired in migrant worker children. Exercise heart rates and post-exercise blood lactic acid levels in response to a standardized bicycle-ergometer work test were significantly higher in migrant worker compared to wel1-to-do children. In addition, a significant correlation was found between anthropometric indicators of nutritional status and parameters of physical work performance. Finally, socio-economic and ecological assessment indicated that the living conditions of migrant worker children were impoverished and unsanitary. This probably aggravated health problems such as infections that were found to occur among these children. Well-to-do children did not share these conditions. / Land and Food Systems, Faculty of / Graduate

O PETI tem como foco de atuação uma jornada ampliada, que é feita no horário oposto ao escolar. Essa jornada tem como objetivo impedir que as crianças trabalhem nesse período e desenvolvam suas potencialidades. Dentro da proposta do programa, estão contempladas as práticas físico-esportivas que ocorreriam dentro da jornada ampliada. Sendo assim os profissionais de Educação Física possuem um novo local de atuação com um potencial magnífico para quem deseja atuar com o objetivo de conseguir reais transformações sociais. No entanto, não conseguimos encontrar nenhum estudo ou pesquisa sobre a atuação do profissional do professor Educação Física (ou mesmo profissionais não graduados) dentro do PETI. De esta forma, este trabalho tem a pretensão de iniciar o preenchimento dessa lacuna utilizando uma metodologia de observação e análises da estrutura do projeto em diferentes unidades do PETI de Sumaré complementado com questionários aos profissionais envolvidos nestes Programas detectando erros e acertos que ocorrem e assim desenvolver esse programa que tem um grande potencial transformador. / Abstract: The projects of redistribution of government are responsible today for millions of reais injected into different programs with varying goals, but with a common stimulus, the provision of a cash payment for people to remain within the programs. I had the opportunity to work in one of those programs was the Program of Eradication of Child Labor (PETI) of Sumaré. PETI has its focus on an Extended Journey, which is made in the schedule opposite the school. This Journey is intended to prevent children from working during that period and develop their potential. Within the context of the program are covered by the physical and sport practices that occur within the Extended Journey. Thus the Physical Education professionals have a new place of work with a wonderful potential for those who want to work with the goal of achieving real social change. However, I could not find any study or research on the role of professional physical education teacher (or even non-professional graduates) within the Committee. In this way, this work has the intention to start filling this gap using a methodology of observation and analysis of the project structure in different units of gestational PETI. / Mestrado / Educação Fisica e Sociedade / Mestre em Educação Física
