Item Adiposity indicators as a screening method for polysomnography in shift workers.(2019) Diniz, Amanda Popolino; Fajardo, Virgínia Capistrano; Freitas, Silvia Nascimento de; Oliveira, Fernando Luiz Pereira de; Nascimento Neto, Raimundo Marques do; Pimenta, Fausto Aloísio Pedrosa; Coelho, George Luiz Lins MachadoObjective: to verify the discriminatory power of adiposity indicators in the prediction of obstructive sleep apnoea (OSA) in shift workers. Methods: a crosssectional study carried out in an iron ore extraction company, in Minas Gerais, Brazil. Anthropometric data were collected and polysomnography (PSG) was performed in 118 male shift workers who owned at least one overall risk factor for cardiovascular disease. Results: the OSA prevalence in the sample was 84.7%. Among the adiposity indicators used to predict OSA (≥ 5 events/hour), body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), and total body fat (TBF) showed sensitivity values higher than 70%. Visceral fat (VF), neck circumference (NC), and neck-to-height ratio (NHtR) were the most effective in correctly identifying workers without OSA (specificity values higher than 70%). The areas under the receiver operating characteristic (ROC) curves for WC and NHtR were greater than 0.7, which indicated the test was effective in discriminating individuals with OSA. Conclusions: alterations in abdomen and neck adiposity indicators have a significant relationship with the presence of OSA and showed effectiveness as a screening method for PSG. WC and NHtR are considered good indicators for OSA prediction.Item Hypovitaminosis D is associated with visceral adiposity, high levels of low-density lipoprotein and triglycerides in alternating shift workers.(2016) Batista, Aline Priscila; Ambrosim, Ticiana Vazzoler; Nascimento Neto, Raimundo Marques do; Pimenta, Fausto Aloísio Pedrosa; Freitas, Silvia Nascimento de; Lauria, Márcio Weissheimer; Coelho, George Luiz Lins MachadoBackground: Studies suggest that there is a strong association between low vitamin D levels and cardiovascular disease (CVD) and its risk factors (RFs). Hypovitaminosis D (25(OH)D < 30 ng/mL or 75 nmol/L) is a recent public health problem that has reached different populations. The objective of the study was to investigate whether hypovitaminosis D is an additional mechanism to explain the disturbances in the lipid profile as well as the excess of abdominal fat presented by alternating shift workers of a mining company in the region of Inconfidentes, Minas Gerais, Brazil. Methods: A cross-sectional study was conducted in a sample of 391 adult males, aged 20 - 57 years old and working alternating shifts, who had at least one risk criterion for CVD. Demographic, behavioral, clinical, and anthropometric and body composition variables were obtained. A blood sample was drawn for determining 25(OH) D, parathyroid hormone intact molecule, lipid profile, blood glucose, insulin, C-reactive protein, and adipokines. Results: The average age of the 391 study participants was 36.1 ± 7.3 years. The percentage of hypovitaminosis D and dyslipidemia was 73% and 74.2%, respectively. Excess visceral fat was significant in the hypovitaminosis D group, with an odds ratio (OR) of 2.4 (95% confidence interval (CI): 1.1 - 5.2). Dyslipidemia showed 25(OH)D levels significantly lower (OR: 2.7, 95% CI: 1.6 - 4.3) than in individuals with normal levels of cholesterol and fractions, and triglycerides. After adjusted the analysis by age and seasonality, the vitamin levels had a significant inverse association and dose-dependent with lowdensity lipoprotein (OR: 5.9), triglycerides (OR: 2.3) and visceral fat area (OR: 2.4). Conclusion: Hypovitaminosis D and dyslipidemia were found in the majority of our mining company shift workers. Furthermore, excess visceral adiposity, hypertriglyceridemia and high low-density lipoprotein cholesterol levels are strong predictors of hypovitaminosis D.Item Hypercholesterolemia among servers at a public university in Minas Gerais.(2014) Fiorezi, Janaina Maria Setto; Bonolo, Palmira de Fátima; Franceschini, Sylvia do Carmo CastroA hipercolesterolemia e importante fator de risco para o desenvolvimento de doenças cardiovasculares, o que representa problema de saude publica. O objetivo deste trabalho foi verificar a frequencia de hipercolesterolemia entre servidores atendidos em servico de saude de uma universidade publica mineira. Trata-se de estudo transversal, de abordagem quantitativa, cujos dados foram coletados no banco de dados do laboratorio de analises clinicas do servico de saude. A populacao estudada foi constituida de 662 servidores (docentes e servidores tecnico-administrativos) ativos da universidade, de ambos os sexos, de 19 a 65 anos de idade. A hipercolesterolemia esteve presente em 51,7% dos exames, sendo que a idade media foi de 52,9 } 7,6 anos e o valor medio de CT de 205,3 } 42,9 mg/dL. Houve diferenca de medias de colesterol total (p=0,026) e idade (p=0,021). A analise da frequencia de fatores de risco cardiovasculares modificaveis entre trabalhadores de uma instituicao possibilita planejar politicas de atencao a saude do trabalhador.
