1) To synthesize the current observational evidence for the association between sedentary behavior and health outcomes using information from systematic reviews. 2) To assess the methodological quality of the systematic reviews found. Medline; Excerpta Medica (Embase); PsycINFO; and Web of Science were searched for reviews published up to September 2013. Additional publications were provided by Sedentary Behaviour Research Network members. The methodological quality of the systematic reviews was evaluated using recommended standard criteria from AMSTAR. For each review, improper use of causal language in the description of their main results/conclusion was evaluated. Altogether, 1,044 review titles were identified, 144 were read in their entirety, and 27 were included. Based on the systematic reviews with the best methodological quality, we found in children and adolescents, strong evidence of a relationship between time spent in sedentary behavior and obesity. Moreover, moderate evidence was observed for blood pressure and total cholesterol, self-esteem, social behavior problems, physical fitness and academic achievement. In adults, we found strong evidence of a relationship between sedentary behavior and all-cause mortality, fatal and non-fatal cardiovascular disease, type 2 diabetes and metabolic syndrome. In addition, there is moderate evidence for incidence rates of ovarian, colon and endometrial cancers. This overview based on the best available systematics reviews, shows that sedentary behavior may be an important determinant of health, independently of physical activity. However, the relationship is complex because it depends on the type of sedentary behavior and the age group studied. The relationship between sedentary behavior and many health outcomes remains uncertain; thus, further studies are warranted.

In the last decade, sedentary behavior has emerged as a new risk factor for health. The elderly spend most of their awake time in sedentary activities. Despite this high exposure, the impact of this sedentary behavior on the health of this population has not yet been reviewed. We systematically reviewed evidence for associations between sedentary behavior and multiple health outcomes in adults over 60 years of age.

El abordaje de la interseccionalidad emergió a fines de la década de 1980, en el campo del activismo feminista negro en EEUU, como crítica a los análisis unidimensionales de las desigualdades sociales. Esta revisión narrativa descriptivo-analítica presenta el estado actual de la inclusión teórico-metodológica de la interseccionalidad en la salud pública. Se consultaron siete bases de bibliografía científica: Web of Science, Embase, Cinahl, Scopus, Sociological Abstracts, Lilacs y Medline, y se obtuvieron 1.763 artículos. Eliminados los duplicados y leídos los títulos y resúmenes, se seleccionaron 30 artículos producidos en cinco países entre 2006 y 2017. El análisis, estructurado en tres temas (debates teórico-metodológicos; marcadores sociales –género, raza, etnicidad, orientación sexual–; y políticas y prácticas de salud), muestra que la interseccionalidad es un recurso analítico prometedor para la comprensión y el enfrentamiento del desafío global de las desigualdades en salud.

Physical activity in adolescents is associated with short- and long-term health benefits. Physical activity can occur in various domains and is influenced by a complex network of factors. The aims of this study are 1) to describe the physical activity of Brazilian adolescents in physical education classes, during leisure time, and during active commuting and 2) to investigate the socio-demographic and behavioral factors associated with physical activity.

Resumo O objetivo do artigo é explorar e sistematizar o conhecimento a respeito dos determinantes estruturais da saúde, por meio da revisão de escopo nas bases de dados: Web of Science, Cinahl, Scopus, Lilacs e PubMed e nas revistas: International Journal of Epidemiology, Journal of Epidemiology and Community Health, American Journal of Public Health e American Journal of Epidemiology no período de 2005 a 2018, pelos termos de busca: Social Determinants of Health, Health Services, Health Policies, e Inequity. Como resultado, foram identificados 1.164 artigos e selecionados 19. Os determinantes estruturais, também chamados marcadores sociais, foram: raça, gênero, identidade de gênero, migração e classe social. As perspectivas teóricas direta ou indiretamente assumiram a saúde como direito. As políticas de saúde propostas tiveram como foco o impacto positivo na equidade através de funções de planejamento; capacitação de prestadores de serviços; redução de barreiras ao acesso e participação dos grupos excluídos. Assim, a literatura científica reforça que todo indivíduo deve ter a capacidade de alcançar seu estado de saúde ideal sem qualquer distinção de raça; cor da pele; religião; idioma; nacionalidade; recursos socioeconômicos; gênero; orientação sexual; identidade de gênero; incapacidade física, mental ou emocional; ou qualquer outra característica ligada à discriminação ou à exclusão de oportunidades sociais e políticas.
