Time worked in shifts and occurrence of drowsiness events while driving: Attenuating effect of physical activity
A longer history of shift work time increases the chance of drowsiness events during driving, but higher physical activity levels mitigate them
The role of sunlight in sleep regulation: Analysis of morning, evening and late exposure
Morning sunlight exposure influences the regulation of the sleep midpoint and overall sleep quality. These findings highlight the potential role of morning sun exposure in aligning circadian rhythms and improving sleep health
Combinations of physical activity, sedentary behavior and sleep and their associations with cardiovascular risk
The combination of high MVPA, low SB and good sleep quality, was associated with a less CVR. These findings highlight the importance of integrated interventions addressing multiple movement behaviors to prevent and treat CVR

Covid-Inconfidentes: How did Covid-19 and work from home influence the prevalence of leisure-time physical inactivity? An analysis of before and during the pandemic
The results suggest that the COVID-19 pandemic negatively influenced PA, substantially increasing the prevalence of PI. The determinants associated with PI were education, body mass index, and work from home
Percentage of energy contribution according to the degree of industrial food processing and associated factors in adolescents (EVA-JF study, Brazil)
Objective: To evaluate energetic contribution according to the degree of industrial food processing and its association with sociodemographic, anthropometric, biochemical, clinical and behavioural characteristics in adolescents. Design: Cross-sectional study (Adolescent Lifestyle Study). Food consumption was assessed using 24-h dietary recalls, with foods classified by degree of industrial progressing. The usual diet was estimated using the Multi…
Aranãs do médio Jequitinhonha: Aspectos socioeconômicos, demográficos e sanitários de uma população indígena desaldeada
A deficiência de dados para subsidiar a análise das condições epidemiológicas e ambientais em que vivem os povos indígenas no Brasil constitui desafio para a elaboração de políticas públicas específicas. O déficit informacional é ainda maior para os grupos “desaldeados”. Diante desse cenário, julgou-se relevante caracterizar uma população indígena desaldeada, privilegiando as dimensões demográfica, socioeconômica e sanitária. Buscou-se identifica…
Perfil nutricional dos indígenas Xukuru-Kariri, Minas Gerais, de acordo com diferentes indicadores antropométricos e de composição corporal
O objetivo deste artigo foi avaliar o perfil nutricional dos indígenas Xukuru-Kariri entre 7 anos e 78 anos aldeados em Minas Gerais de acordo com os diferentes indicadores antropométricos e de composição corporal . As medidas aferidas foram: peso, estatura, circunferência da cintura (CC) e percentual de gordura corporal (%GC).

Prevalência de parasitos intestinais na comunidade indígena Maxakali, Minas Gerais, Brasil, 2009
O objetivo deste estudo foi determinar a prevalência de parasitos intestinais na etnia Maxakali em Minas Gerais, Brasil. Os exames parasitológico das fezes foram realizados através da técnica TF-Test, sendo as amostras fecais coletadas em três dias alternados, em tubos independentes, contendo formol a 10%, unificados para dupla filtragem por centrifugação. Triplicatas de uma alíquota do sedimento foram examinadas em microscópio (10x e 40x) para i…

Visceral leishmaniasis in large Brazilian cities: Challenges for Control
The objectives of this article were to discuss the rapid spread of visceral leishmaniasis in urban areas of Brazil and to raise practical questions and perspectives related to control of the disease. Among the proposed methods, the elimination of seropositive dogs is the most controversial and least accepted by society. Its impact on incidence rates varies among studies (positive in some and relatively unimportant in others). Treatment of infecte…
Fecundidade das mulheres autodeclaradas indígenas residentes em Minas Gerais, Brasil: Uma análise a partir do Censo Demográfico 2000
As populações indígenas aldeadas no Brasil apresentam alta taxa de fecundidade total (TFT), sendo que em alguns casos é observado o crescimento destas taxas ao longo do tempo. Já os dados do Instituto Brasileiro de Geografia e Estatística (IBGE) revelam um declínio da TFT da população autodeclarada indígena, independente da situação de domicílio (urbano, rural e rural específico). Este trabalho utiliza dados do Censo Demográfico 2000 para descrev…
