    (2023) Menezes Junior, Luiz Antonio Alves de; Fajardo, Virgínia Capistrano; Nascimento Neto, Raimundo Marques do; Freitas, Silvia Nascimento de; Oliveira, Fernando Luiz Pereira de; Pimenta, Fausto Aloísio Pedrosa; Coelho, George Luiz Lins Machado; Meireles, Adriana Lúcia
    Objective To evaluate the association between sleep parameters and hypovitami- nosis D in rotating shift drivers. Material and Methods We conducted a cross-sectional study on 82 male rotating shift workers (24–57 years old) with at least one cardiovascular risk factor (such as hyperglycemia, dyslipidemia, abdominal obesity, physical inactivity, hypertension, and smoking). Polysomnography was used to evaluate sleep parameters. Logistic regres- sion was used to model the association between hypovitaminosis D and sleep parameters after adjustment for relevant covariates. Results Hypovitaminosis D (< 20 ng/mL) was seen in 30.5% of the workers. Shift workers with hypovitaminosis D had lower sleep efficiency (odds ratio [OR]: 3.68; 95% confidence interval [CI]: 1.95–5.53), lower arterial oxygen saturation (OR: 5.35; 95% CI: 3.37–6.12), and increased microarousal index (OR: 3.85; 95% CI: 1.26–5.63) after adjusting. Conclusion We suggest that hypovitaminosis D is associated with greater sleep disturbances in rotating shift workers.

    (2021) Menezes Junior, Luiz Antonio Alves de; Fajardo, Virgínia Capistrano; Nascimento Neto, Raimundo Marques do; Freitas, Silvia Nascimento de; Oliveira, Fernando Luiz Pereira de; Pimenta, Fausto Aloísio Pedrosa; Coelho, George Luiz Lins Machado; Meireles, Adriana Lúcia
    Background Data on the validity of tools for sleep apnea risk detection in rotating shift workers are limited. The aim was to evaluate the Berlin questionnaire (BQ) and the Neck, Obesity, Snoring, Age, Sex (NoSAS) score for the detection of obstructive sleep apnea risk in shift workers. Methods This cross-sectional study included male rotating shift workers, drivers of heavy of-road machinery in an iron ore extraction company. Polysomnography was the gold standard for evaluation. Obstructive sleep apnea (OSA) was defned as an apnea–hypopnea index (AHI) of≥5 events/h. The Shapiro–Wilk test verifed the data distribution and comparative analysis was conducted using the chi-square analyses and U Mann–Whitney with Bonferroni correction. Receiver operating characteristic curve analysis, sensitivity, specifcity, positive and negative predictive values, positive and negative likelihood ratios, and accuracy were used for evaluate BQ and NoSAS with OSA diagnosis by polysomnograph. Results Among 119 male shift workers, ages 24 to 57 years, polysomnography showed that 84% had obstructive sleep apnea (AHI≥5), and 46% had moderate to severe sleep apnea (AHI≥15). For AHI≥5, the NoSAS score had higher sensitivity and specifcity than the BQ. For AHI≥15 and AHI≥30, the NoSAS score had a sensitivity higher than 70% while BQ was 60% and 58%, respectively. The accuracy of the NoSAS score was higher for all OSA criteria than that of BQ. Conclusion In rotating shift workers, drivers of heavy of-road machinery, the NoSAS score showed higher accuracy in identifying patients at risk for sleep apnea than the BQ.

    Distúrbios do sono em trabalhadores de turno alternante : validação de método e relação com hipovitaminose D.
    (2020) Menezes Junior, Luiz Antonio Alves de; Meireles, Adriana Lúcia; Nascimento Neto, Raimundo Marques do; Meireles, Adriana Lúcia; Nascimento Neto, Raimundo Marques do; Freitas, Lunara da Silva; Carraro, Júlia Cristina Cardoso
    Introdução: A jornada laboral em turnos tem sérios impactos na saúde dos trabalhadores devido a dessincronização do sistema circadiano. Como consequências, esses trabalhadores apresentam mais distúrbios do sono e transtornos endócrino-metabólicos relacionados com diversas comorbidades, como obesidade, hipertensão e hipovitaminose D. A vitamina D além de suas funções na homeostase óssea, tem sido implicada em um número crescente de mecanismos fisiológicos, incluindo o sono. Objetivos: Validar um método de avaliação de distúrbios do sono e verificar a relação de distúrbios do sono com os níveis de vitamina D em trabalhadores de turno alternante. Métodos: Estudo de delineamento transversal com trabalhadores de turnos alternantes, adultos do sexo masculino da região do Quadrilátero Ferrífero, Minas Gerais, realizado nos anos de 2011 e 2012. Foi realizada avaliação antropométrica, clínica e bioquímica, além de questões sociodemográficas, comportamentais e do sono. Avaliação do sono realizada por dois métodos, o exame de polissonografia e o questionário de Berlim (QB). O exame de polissonografia foi realizado durante a noite, de 22:00 horas às 06:00 horas, e avaliado tempo total, latência, eficiência e estágios do sono, além do índice de apneia-hipopneia, movimento periódico de pernas e saturação arterial de oxigênio. O QB foi utilizado como ferramenta indireta para avaliar o risco para apneia obstrutiva do sono (AOS). O estudo foi composto por duas amostras: amostra 1 que foi utilizada para validação do QB (n= 119) e amostra 2 para avaliar a relação dos distúrbios do sono medidos pela polissonografia com os níveis de vitamina D (n= 82). Foi realizada a avaliação da validade do QB original e com alterações na categoria 3 [(QB1 modificado: IMC > 30,0 kg/m²); (QB2 modificado: IMC > 25,0 kg/m²)] para avaliar o risco para AOS em trabalhadores de turno alternante. Para esta etapa, a análise estatística incluiu teste Kappa, análise de curva ROC e análise dos valores diagnósticos. Para avaliar a relação entre os níveis de vitamina D (25(OH)D) e distúrbios do sono, medidos pelo exame de polissonografia, a análise estatística incluiu o teste qui-quadrado de Pearson, ou teste exato de Fisher, para duas variáveis categóricas. E para variáveis contínuas, o teste T de Student ou U de Mann-Whitney, para variáveis com distribuição normal e não normal, respectivamente. Resultados: A amostra total foi composta por 119 trabalhadores com idade mediana de 34 anos. A hipovitaminose D (25(OH)D < 20 ng/mL) foi observada em 23,0% da amostra. Na etapa de validação do QB, 16,8% dos trabalhadores apresentaram alto risco para AOS segundo o QB. O QB2 modificado foi o que obteve melhor acurácia, sensibilidade e especificidade. Avaliando a relação da vitamina D com parâmetros da polissonografia, foi encontrado que indivíduos com hipovitaminose D (25(OHD < 20 ng/mL) apresentaram maior latência e menor eficiência do sono, quando comparados aos trabalhadores com níveis normais desta vitamina (25(OHD > 20 ng/mL). Conclusão: Em trabalhadores de turno alternante, o QB mostrou acurácia reduzida na identificação de pacientes com AOS e deve ser usado com cautela na seleção de pacientes para polissonografia. Ademais, observamos que trabalhadores com hipovitaminose D apresentam maior latência e menor eficiência do sono, do que aqueles com níveis normais desta vitamina.

    (2022) Menezes Junior, Luiz Antonio Alves de; Andrade, Amanda Cristina de Souza; Coletro, Hillary Nascimento; Mendonça, Raquel de Deus; Menezes, Mariana Carvalho de; Coelho, George Luiz Lins Machado; Meireles, Adriana Lúcia
    Background and aims: Consumption of ultra-processed foods is negatively associated with health out- comes, however, the contribution to sleep quality is limited. Therefore, the objective of this study was to evaluate the association between food intake by frequency and degree of processing and sleep quality in adults during the covid-19 pandemic. Methods: Population-based survey of adults from October to December 2020 in the Iron Quadrangle region, Brazil. The exposure variable was a food intake score that considered the frequency of con- sumption and food processing degree. The total score ranged from 0 (best) to 48 points (worst food quality), categorized into quartiles. Furthermore, we also evaluated whether individuals replaced their lunch and/or dinner based mostly on fresh/minimally processed foods for ultra-processed foods, for five or more days in the week. The outcome variable was sleep quality assessed with the Pittsburgh Sleep Quality Index. We constructed a contrasting directed acyclic graph (DAG) model to estimate the adjusted odds ratio of the association between score eating and sleep, by logistic regression. Results: Most of the 1762 individuals evaluated had poor sleep quality (52.5%). The minimum and maximum food scores were 0 and 30 points (mean 9.16; 95% CI 8.50, 9.81). The higher values of the score corresponded to lower consumption of fresh and minimally processed foods and higher consumption of ultraprocessed foods. In multivariate analysis, individuals in the third food consumption score had 71% greater odds of poor sleep quality (OR 1⁄4 1.71; 95% CI: 1.03, 2.85) and in the fourth quartile 144% greater odds (OR 1⁄4 2.44; 95% CI: 1.32, 2.44). Besides, replacing the dinner meal with ultra-processed foods five days or more in the week was also associated with poor sleep quality (OR 1⁄4 2.01; 95%CI: 1.14, 3.57). Conclusion: Higher consumption of ultra-processed foods concomitant with lower consumption of fresh and minimally processed foods is associated with a higher chance of poor sleep quality.

    Rotating shift workers with vitamin D defciency have a higher risk of obstructive sleep apnea.
    (2022) Menezes Junior, Luiz Antonio Alves de; Fajardo, Virgínia Capistrano; Freitas, Silvia Nascimento de; Coelho, George Luiz Lins Machado; Oliveira, Fernando Luiz Pereira de; Nascimento Neto, Raimundo Marques do; Meireles, Adriana Lúcia
    Objectives The study aimed to evaluate the association between obstructive sleep apnea (OSA) and vitamin D defciency (VDD) in shift workers. Methods This cross-sectional study included male rotating shift workers in an iron ore extraction company. Participants were classified as VDD when 25(OH)D < 20 ng/mL for a healthy population and 25(OH)D < 30 ng/ mL for groups at risk for VDD. Risk of developing OSA was classified by Berlin questionnaire (BQ) and NoSAS score. Data were compared using chi-square analysis with Cramer’s V as effect size, and Bonferroni correction. Multivariate logistic regression analysis was performed to investigate whether or not VDD was associated with OSA risk assessment. Results Among 1423 male workers, mostly younger, aged 30 to 39 years (53%), worked shifts for more than 5 years (76%). The prevalence of high risk of OSA by BQ was 16%, and 33% by NoSAS score. Additionally, 29% had VDD. In multivariate analysis, controlled for confounding factors, workers with VDD had a 52% increased chance of OSA by BQ (OR 1.52; CI95% 1.06–2.18) and a 64% increased chance of OSA by NoSAS score (OR 1.64; CI95% 1.09–2.48). After subgroup analyses, similar results were not observed in workers aged 20–29 and 30–39 years. Conclusion Rotating shift workers with vitamin D defciency are more likely to have obstructive sleep apnea, assessed by the Berlin questionnaire and NoSAS score.

    Work hours as a risk factor for SARS-CoV-2 infections : cardiometabolic and sleep characteristics in rotating shift workers.
    (2022) Nascimento, Raiza Aranha; Fajardo, Virgínia Capistrano; Menezes Junior, Luiz Antonio Alves de; Mendonça, Pedro Henrique Marques; Nascimento, Maria Cristina Veiga Aranha; Tristão, Pedro Marques Oliveira; Oliveira, Fernando Luiz Pereira de; Nascimento Neto, Raimundo Marques do
    This study aims to describe the health characteristics of rotating shift mining workers that may be related to a worse course scenario for COVID-19, according to literature data. Methods: Is a cross-sectional from three studies with 1478 shift workers. Social, demographic, clinical, and biochemical variables were analyzed. Risk factors for COVID-19 analyzed: hyperglycemia, altered blood pressure, dyslipidemia, hypovitaminosis D, obesity, presence of pre-existing cardiovascular diseases, and smokers. Results: Evaluating the grouped risk factors for an unfavorable evolution of COVID-19 most workers (91.0%) presented at least one risk factor. Discussion: With coronavirus in pandemic circulation, we noticed that mineworkers are in a vulnerable position. Their exposure to occupational risk factors, to the shift system, which directly affects sleep and negatively influences immunity, added to the conditions of favorable transmissibility by the flow of people from the mines leads us to believe in their greater susceptibility to acquiring the most serious forms of the disease.
