“…This study included 763 participants ( Table 1 ), it was similar in size or larger than published studies that have looked at the characteristics of the Amazonian riverine population [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ].…”

The Amazon River basin is the largest tropical forest in the world. Most of the Amazon belongs to Brazil, a developing country that currently faces huge challenges related to the consolidation of its universal healthcare system. Noncommunicable diseases (NCDs) are the leading cause of death in Brazil, accounting for 74% of all deaths, and NCDs are probably underestimated in Amazonian population because of their geographical isolation and the precariousness of riverine communities. Important risk factors, such as genetic susceptibility, remain undetermined in the riverine population. This study performed fasting blood sugar (FBS) and blood pressure measurements and investigated the presence of the ε4 allele of apolipoprotein E (APOE4) to determine the prevalence of diabetes, hypertension and the genetic risk of NCDs. FBS and APOE4 were measured in blood samples from 763 participants using spectrometry and real-time PCR; 67.5% showed altered measurements, and 57.9% had never been diagnosed or treated. Altered FBS was found in 28.3% of the participants, hypertension in 57.6% and APOE4 in 32.0%. The health profile of the riverine population appears to differ from that of urban population in the Amazon. Additional risk factors for NCDs, such as environmental contamination and nutritional transition, may contribute more than increased genetic susceptibility to the prevalence of altered FBS and hypertension. Our results will help guide the development of preventive strategies and governmental actions for more effective management of NCDs in the Amazon area.

“…Moreover, it has been reported that the Amazon population is highly exposed to mercury (Hg) from diet [31,32,43,44], and high Se intake may counterpoise Hginduced toxic effects because they interact to form the selenite-dimethylmercury complex, which is unstable in blood and in other tissues [45]. effects of higher Se levels on motor performance [46] and reduced risk for cataracts [47], Se toxicity may be associated with longer-term disturbances, such as diabetes and cardiovascular disease [2,41,48], and further study is warranted to fully establish the long-term safety of Se supplementation through diet.…”

“…methyl mercury) can occur in the human body and therefore, part of the mercury detected in urine (i.e inorganic mercury) could come from organic sources such as fish ingestion (Abdelouahab et al, 2008;Passos et al, 2007). Mercury contamination of fish is widely spread in the region and it is well known health risk affecting many of the indigenous peoples living along the Amazonian rivers and tributaries who rely on subsistence fishing (Faial et al, 2015;Olivero-Verbel et al, 2016;Weinhouse et al, 2017).…”

Most oil extraction areas in the Peruvian Amazon are within indigenous territories. Poor environmental practices have exposed the indigenous population to metals. We conducted a survey in two indigenous Kukama communities to assess body burdens of metals after the occurrence of two major oil spills in 2014. Urine levels above those recommended by the Peruvian Ministry of Health were observed in 50% and 17% of the study population for mercury and cadmium, respectively.
