ABSTRACT
RESUMO A presente revisão de escopo objetivou evidenciar o perfil das pesquisas brasileiras que investigam os desfechos em saúde ocasionados pela exposição a agrotóxicos, procurando entender os principais achados, tais como metodologia empregada, tipo de substância, desfechos em saúde, locais investigados, sugestões de ações e diálogo com a agroecologia. Foi utilizada a metodologia 'scoping review', seguindo o modelo Prisma-ScR. Entre os 83 artigos encontrados, 61 estudaram os/as agricultores/as e 22 estudaram outros grupos populacionais. Houve predomínio de estudos primários e quantitativos, seguidos por revisões sistemáticas. Do total, 79 encontraram desfechos, com destaque aos danos hematológicos e genéticos, em sua maior parte causados pela intoxicação por mais de 1 agrotóxico. O maior número de estudos foi realizado na região Sul, seguida das regiões Sudeste, Nordeste, Centro-Oeste e Norte. Apenas uma pesquisa sugeriu a transição agroecológica enquanto solução para a problemática. Conclui-se que, perante um cenário de crescimento do uso de agrotóxicos, fazem-se urgentes proposições de ações intersetoriais e que não envolvam somente educação em saúde ou o setor saúde de forma isolada, como sugere a maioria dos artigos, sendo necessária a articulação entre setores ligados à agricultura, abastecimento, educação, saúde e meio-ambiente.
ABSTRACT The present scope review aimed to highlight the profile of Brazilian research that investigates health outcomes caused by exposure to pesticides, seeking to understand the main findings, such as methodology used, type of substance, health outcomes, investigated locations, suggested actions, and dialogue with agroecology. The scoping review methodology was used, following the Prisma-ScR model. Among the 83 articles found in the review, 61 studied farmers and 22 studied other population groups. There was a predominance of primary and quantitative studies, followed by systematic reviews. Of the total, 79 articles found outcomes, with emphasis on hematological and genetic damage, mostly caused by poisoning by more than 1 pesticide. The largest number of studies were carried out in the South, followed by the Southeast, Northeast, Midwest, and North. Only 1 survey suggested the agroecological transition as a solution to the problem. It is concluded that, faced with a scenario of growth in the use of pesticides, it is urgent to have proposals for intersectoral actions and that do not involve only health education or the health sector in isolation, as most articles suggest, requiring articulation between sectors related to agriculture, supply, education, health, and the environment.
ABSTRACT
BACKGROUND: Bitterness perception seems to be related to an enhanced intake of dietary fat and to a tendency to the development of diseases such as obesity. However, the exact factors for this possible contribution still need to be better investigated. So, gustatory perception of the bitter taste is a promising area of study because of its importance regarding food choices and consequently feeding behavior. Therefore, this short review focused on recent papers reporting correlations between bitter taste, anthropometric variables, obesity and other chronic diseases, age, gender, ethnicity, and genetics. METHODS: A survey was performed in MEDLINE (PubMed) and Scielo from September 2015 to January 2017.Only review articles, observational studies and clinical trials published in English and Portuguese over the last15 years which met the objectives of the present study were considered. A total of 40 papers were evaluated. RESULTS: Two papers showed a positive correlation between bitter taste and obesity, one indicated that this correlation is influenced by the subject's age, one suggested a negative correlation, and two found no association. Age seems to be negatively correlated with the bitterness perceived, and female gender was associated with a stronger perception of bitterness. Genetics, mostly due to differences in TAS2R38 expression, influences sensitivity to the bitter taste, feeding behavior and also alcohol intake. Ethnicity, not only the subject's phenotypic or genotypic characteristics, seems to play a role in taste perception and nutritional diseases. CONCLUSIONS: Age, gender, genetics and ethnicity seem to play a role in bitterness perception. Data about associations between bitterness perception and anthropometrics are conflicting.
