Frozen chicken for wild fish: nutritional transition in the Brazilian Amazon region determined by carbon and nitrogen stable isotope ratios in fingernails.

Amazonian populations are experiencing dietary changes characteristic of the nutrition transition. However, the degree of change appears to vary between urban and rural settings. To investigate this process, we determined carbon and nitrogen stable isotope ratios in fingernails and dietary intake of Amazonian populations living along a rural to urban continuum along the Solimões River in Brazil.

Obesity, hypertension, social determinants of health and the epidemiologic transition among traditional Amazonian populations

Abstract Background: The health and nutritional situation of adults from three rural vulnerable Amazonian populations are investigated in relation to the Social Determinants of Health (SDH) and the epidemiologic transition. Aim: To investigate the role of the environment and the SDH on the occurrence of chronic-degenerative diseases in these groups. Subjects and methods: Anthropometric, blood pressure and demographic data were collected in adults from the RDS Mamirauá, AM (n = 149), Flona Caxiuanã, PA (n = 148) and quilombolas, PA (n = 351), populations living in a variety of socio-ecological environments in the Brazilian Amazon. Results: Adjusting for the effect of age, quilombola men are taller (F = 9.85; p < 0.001) and quilombola women present with higher adiposity (F = 20.43; p < 0.001) and are more overweight/obese. Men from Mamirauá present higher adiposity (F = 9.58; p < 0.001). Mamirauá women are taller (F = 5.55; p < 0.01) and have higher values of waist circumference and subscapular/triceps index. Quilombolas present higher prevalence of hypertension in both sexes and there are significant differences in rates of hypertension among the women (χ2 = 17.45; p < 0.01). The quilombolas are more dependent on government programmes, people from Mamirauá have more economic resources and the group from Caxiunã have the lowest SES. Conclusion: In these populations, the SDH play a key role in the ontogeny of diseases and the ‘diseases of modernity’ occur simultaneously with the always present infectoparasitic pathologies, substantially increasing social vulnerability.

Mudancas sociais e gestao ecologica em questao: A experiencia de Mamiraua

Estudo sobre as mudancas sociais que envolveram as populacoes tradicionais desde a criacao de uma unidade de conservacao ambiental, no ano de 1990, na regiao do Medio Solimoes, Amazonia brasileira, com o interesse de conservar uma area reconhecida como o maior ecossistema de varzea do mundo. A analise situa os produtores locais em relacao ao mercado ecologico e aos agentes do desenvolvimento sustentavel. O estudo se refere a 49 localidades da floresta alagada amazonica, com informacoes relativas aos anos de 1991 a 2006. A analise identifica os agentes sociais que integram o campo socioambiental que se constroi com as politicas de intervencao socioambiental.
