ABSTRACT Objective: To identify dietary patterns in an adult population and to verify the factors associated with them. Methods: We conducted a cross-sectional population-based household study with 1,574 individuals aged >20 years, of both sexes, living in Teresina and Picos, Piauí, Brazil. Sociodemographic, lifestyle and food consumption data were collected. Dietary patterns were obtained using principal component analysis. Results: There was a positive and significant association with the healthy eating pattern in women, elderly people, individuals with secondary and higher education and smokers. The white-meat pattern was positively associated with people without a partner and non-white skin, as well as with women, elderly people and smokers, and inversely with individuals with longer screen time and individuals with high school and college education. The unhealthy pattern was positively associated with individuals with excessive screen time and individuals with secondary and higher education, and inversely associated with individuals who were insufficiently active. Conclusion: Women, the elderly, individuals with a partner, non-smokers and active people have a healthier diet. However, men, smokers, with longer screen time and insufficiently active had a more inadequate diet, while the level of education showed contrasting results.

RESUMEN Objetivo: Identificar patrones dietéticos en una población de adultos y adultos mayoresy verificar los factores asociados a ellos. Métodos: Estudio transversal poblacional y domiciliario realizado en 1574 personas mayores de 20 años, de ambos sexos, residentes en Teresina y Picos, Piauí, Brasil. Se recogieron datos sociodemográficos, de estilo de vida y de consumo de alimentos. Los patrones dietéticos se obtuvieron mediante análisis de componentes principales. Resultados: Hubo asociación positiva y significativa con el patrón de alimentación saludable en mujeres, adultos mayores, individuos con educación secundaria y superior y fumadores. El patrón de carnes blancas se asoció positivamente con personas sin pareja y piel no blanca, así como con mujeres, personas mayores y fumadores, e inversamente con personas con mayor tiempo de pantalla y personas con educación secundaria y universitaria. El patrón insalubre se asoció positivamente con individuos con tiempo de pantalla excesivo y con individuos con educación secundaria y superior, y se asoció inversamente con individuos que eran insuficientemente activos. Conclusión: Las mujeres, los adultos mayores, las personas en pareja, los no fumadores y las personas activas tienen una dieta más saludable. Sin embargo, los hombres, fumadores, con mayor tiempo de pantalla e insuficientemente activos tenían una dieta más inadecuada, mientras que el nivel de educación mostró resultados contrastantes.

Resumo A ocorrência de acidentes e de doenças relacionadas ao trabalho são expressões concretas da exposição dos trabalhadores aos riscos presentes no ambiente laboral. Historicamente o conflito de interesses entre empregadores e trabalhadores obrigou o Estado a assumir a função de regulação desta relação, instituindo leis e fiscalizando a aplicação das normas de saúde e segurança no trabalho. O Fator Acidentário de Prevenção (FAP) é uma dessas estratégias. O objetivo deste artigo é analisar a correlação entre as taxas de risco de acidentes de trabalho no Brasil antes (2006-2009) e depois (2010-2016) da vigência do FAP. Estudo ecológico com análise temporal de séries de taxas de acidentes de trabalho registrados nas bases de dados da Previdência Social no período 2006 e 2016. A análise incluiu o cálculo das taxas de risco de acidentes segundo grandes regiões brasileiras, divisões do CNAE, motivo/situação, capítulos do CID-10, sexo e idade. A comparação entre os resultados dos dois períodos foi realizada utilizando-se as taxas de risco médias com a aplicação do teste t de Student e da correlação de Spearman. Basicamente todas as séries de taxas analisadas obtiveram forte tendência de redução no período de vigência do FAP, ao contrário do que ocorreu no período imediatamente anterior.

Abstract Historically, the conflict of interests between employers and workers obliged the State to assume the role of regulating this relationship, instituting laws and overseeing the application of health and safety standards at work. The Accident Prevention Factor (FAP) is one of these guidelines. This article aims to analyze the correlations between the FAP and the risk rate for occupational accidents in Brazil in the period between 2006 and 2016. Ecological study, which analyzed the occupational accidents, registered in the Brazilian Social Security database in the period between 2006 and 2016. The analysis included the calculation of accident risk rates according to the Brazilian regions, divisions of the CNAE, reason/situation, ICD-10 chapters, sex and age. The comparison between results from the two periods was performed using the average risk rates from the two periods using Student t test, Spearman correlation and beta value. Basically, all rate series analyzed had a strong downward trend in the FAP period, contrary to what occurred in the immediately previous period.

Abstract Peanut is a crop of the Kayabi tribe, inhabiting the Xingu Indigenous Park, Brazil. Morphological analysis of Xingu accessions showed variation exceeding that described for cultivated peanuts. This raised questions as to the origin of the Xingu accessions: are they derived from different species, or is their diversity a result of different evolutionary and selection processes? To answer these questions, cytogenetic and genotyping analyses were conducted. The karyotypes of Xingu accessions analyzed are very similar to each other, to an A. hypogaea subsp. fastigiata accession and to the wild allotetraploid A. monticola. The accessions share the number and general morphology of the chromosomes; DAPI+ bands; 5S and 45S rDNA loci distribution and a high genomic affinity with A. duranensis and A. ipaënsis genomic probes. However, the number of CMA3+ bands differs from those determined for A. hypogaea and A. monticola, which are also different from each other. SNP genotyping grouped all Arachis allotetraploids into four taxonomic groups: Xingu accessions were closer to A. monticola and A. hypogaea subsp. hypogaea. Our data suggests that the morphological diversity within these accessions is not associated with a different origin and can be attributed to morphological plasticity and different selection by the Indian tribes.
