Temporal patterns of food consumption and their association with cardiovascular risk in rotating shift workers.

OBJECTIVE: We aimed to evaluate the association of temporal patterns of food consumption with cardiovascular disease (CVD) risk. METHODS: This cross-sectional study included male rotating shift workers in an iron ore extraction company. Data on food consumption was collected using a 24 h recall, applied by trained interviewers. The variables for temporal patterns of food consumption were: eating window, eating at night, number of meals and omission of breakfast. CVD-risk was measured by calculating the Framingham coronary heart disease risk score (FCRS), and classified as low risk or intermediate to high risk. Descriptive, univariate and multivariate logistic regression analyses examined the association between variables related to temporal patterns of food consumption and CVD-risk. RESULTS: The study assessed 208 workers, the majority with 20-34 years (45.1%), non-white (77.2%), and 5 years or more in shift work (76.0%). Most participants had a feeding window exceeding 12 h (63.9%), consumed meals until 10 p.m. (68.1%), had five or more meals per day (54.8%), and did not skip breakfast (86.5%). Regarding CVD-risk, 43.8% of the participants were classified with intermediate to high risk for CVD. In the multivariate model, a feeding window (OR: 2.32; 95%CI: 1.01-5.35), eating after 10 p.m. (OR: 3.31; 95%CI: 1.01-11.0), and skipping breakfast (OR: 2.58; 95%CI: 1.07-6.19) increased the likelihood of intermediate to high CVD-risk. Conversely, having five or more meals per day decreased the odds (OR: 0.27; 95%CI: 0.08-0.92). CONCLUSION: Eating window longer than 12 h, eating after 10 p.m., less than four meals a day and omission of breakfast, are associated with cardiovascular risk in shift workers.

Fatty acid intake and prevalence of depression among Brazilian graduates and postgraduates (CUME Study).

BACKGROUND: Dietary fatty acids are related to the development of several inflammatory-related diseases, which may include depression. So, the association between fatty acids, culinary oils and fat intake and depression in highly educated Brazilians was evaluated. METHODS: Multicenter cross-sectional study using baseline data from the Cohort of Universities of Minas Gerais. The diagnosis of depression was self-reported, and the daily intake of fatty acids was assessed using a 144-item food frequency questionnaire (FFQ). RESULTS: A total of 7157 participants (68.83 % women) with a median age of 33 years were included. The prevalence of depression was 12.60 % (N = 902). In the adjusted analyses, it was observed that individuals with the highest intake of omega-6 fatty acids (n-6) (OR: 1.36, 95 % CI 1.11-1.67) had a higher prevalence of depression. This increased n-6 intake was identified as a risk factor for depression only among male participants, while among overweight participants, higher n-6 intake was also positively associated with depression. Conversely, a higher ratio of polyunsaturated to monounsaturated and saturated fatty acids (PM/S) was also found to be positively associated with depression, but this association was observed only among non-overweight participants. No associations were found between the consumption of culinary oils or fats and depression. LIMITATIONS: Cross-sectional design limits the assessment of causality. The use of the FFQ can make estimates more difficult. CONCLUSION: Higher consumption of n-6, and higher PM/S ratios were associated with depression, and individual factors can interfere. The mental health care policies should include specific nutritional strategies.

30-Year High Cardiovascular Risk Incidence and its Determinants: CUME Study.

OBJECTIVE: Estimate the incidence of the 30-year high cardiovascular risk and its determinants among graduates of federal universities in Minas Gerais. METHODS: This is a prospective cohort of 2,854 adults aged 20 to 59. The incidence of the outcome was calculated using the Framingham equation and its determinants were determined through multivariate Cox regression. RESULTS: After an average of 2.62 years, the incidence of high cardiovascular risk was 8.09 and 20.1 cases per 1,000 person-years, for females and males respectively. Being male (HR: 2.34; 95% CI: 1.58 - 3.46), employment (HR: 2.13; 95% CI: 1.13 - 3.99), high consumption of processed foods (HR: 2.44; 95% CI: 1.21 - 4.90), and being physically active (HR: 0.63; 95% CI: 0.41 - 0.98) were associated with high cardiovascular risk. CONCLUSIONS: Among highly educated adults, being male, employment, and high consumption of processed foods are predictors of high cardiovascular risk, while being physically active acts as a protective factor.

Arterial hypertension in rotating shift workers: The role of hypertriglyceridemic waist and hypertriglyceridemic waist-to-height ratio phenotypes.

OBJECTIVE: To examine the association of arterial hypertension and the hypertriglyceridemic waist phenotype (HWP) and hypertriglyceridemic waist-to-height phenotype (HWHP). METHODOLOGY: This cross-sectional study was conducted with 1422 male rotating shift workers in Brazil. The HWP was defined as having a waist circumference ≥94 cm and serum triglycerides ≥150 mg/dL, whereas the HWHP was determined by having a waist-to-height ratio ≥0.5 and serum triglycerides ≥150 mg/dL. To provide a characterization of the sample, data were presented in both absolute and relative values, and Pearson's chi-square test was employed. To investigate the potential association between arterial hypertension and the presence of HWP or HWHP, multivariate logistic regression was conducted, accounting for sociodemographic, behavioral, and clinical variables. Furthermore, we conducted a stratified multivariate logistic regression analysis, considering the duration of shift work, to assess whether the results remained consistent depending on the length of work experience in shifts. RESULTS: A noteworthy association was observed between arterial hypertension and both HWP and HWHP, with HWHP exhibiting a stronger association with the disease. Furthermore, a positive association between arterial hypertension and these phenotypes was identified in workers with five or more years of shift work. CONCLUSION: We recommend the utilization of HWHP as a screening tool, as it indicates a stronger association with arterial hypertension compared to HWP. Additionally, the duration of time spent working in shifts emerged as a significant factor influencing the presence of these phenotypes.

The 30-year cardiovascular risk trajectories and their independently associated factors in participants of a Brazilian cohort (CUME Study).

We aimed to analyze the different trajectories of 30-year cardiovascular risk (CVR) and its independently associated factors in participants of the CUME Study, a prospective study with alumni from federal universities of Minas Gerais State, Brazil. In this study, 1,286 participants who answered the baseline (2016) and follow-up (2018 and 2020) questionnaires were included. Trajectories of CVR, according to the Framingham score, were identified with the latent class growth modelling technique with the use of the censored normal model. Analysis of the factors independently associated with each of the trajectories was conducted with multinomial logistic regression technique. Three CVR trajectories were identified: Low-Low (68.3%), Medium-Medium (26.2%), and High-High (5.5%). Male sex, living in a stable union, and having moderate and high intakes of ultra-processed foods were positively associated with the Medium-Medium and High-High CVR trajectories. Having non-healthcare professional training and working were positively associated with the Medium-Medium CVR trajectory, whereas being physically active was negatively associated with the High-High CVR trajectory. In conclusion, more than one-third of participants had CVR trajectories in the Medium-Medium and High-High categories. Food consumption and physical activity are modifiable factors that were associated with these trajectories; thus, implementing health promotion measures could help prevent the persistence or worsen of CVR. On the other hand, sociodemographic and labor characteristics are non-modifiable factors that were associated with Medium-Medium and High-High trajectories, which could help identify people who should be monitored with more caution by health services.

The predictive values of BOAH and No-apnea score for screening obstructive sleep apnea in rotating shift worker drivers.

Objective: To evaluate the BOAH (Body mass index, Observed apnea, Age, and Hypertension) and No-apnea score's diagnostic values for detecting obstructive sleep apnea (OSA) risk in shift workers. Methods: Cross-sectional study with male rotating shift workers and drivers of heavy off-road machinery. The BOAH score is based on body mass index, witnessed apneas during sleep, age, and hypertension. The No-apnea score is based on neck circumference and age. Based on the apnea-hypopnea index (AHI), the severity of OSA was categorized as least mild OSA (AHI ≥5/h), moderate to severe OSA (AHI ≥15/h), and severe OSA (AHI ≥30/h). Sensitivity, specificity, positive predictive value, negative predictive value, and areas under the curve (AUC) were calculated. Results: Among 119 workers evaluated, 84.0% had AHI ≥5, 46.2% had AHI ≥15, and 14.3% had AHI ≥30. BOAH score with 2 points for AHI ≥5, the AUC was 0.679, and sensitivity and specificity were 41.0% and 94.7%, respectively. No-apnea score with 3 points AHI ≥5, the AUC was 0.692, and sensitivity and specificity were 70.0% and 68.4%, respectively. Furthermore, using at least one of the positive scores, the AUC was higher when compared to the single tests for AHI ≥5 (AUC = 0.727). And when both scores were positive, the AUC was higher for AHI ≥30 (AUC = 0.706). Conclusion: In rotating shift workers and drivers of heavy off-road machinery, BOAH, and No-apnea scores can be helpful tools in identifying individuals at risk for sleep apnea. In addition, matching the scores may increase the prediction of OSA.

Vitamin D deficiency and hyperglycemia in male rotating shift workers: A disturbed circadian rhythms influence.

BACKGROUND: Shift work is related to several negative impacts on the health of workers. This study aimed to evaluate the association between vitamin D deficiency (VDD) and hyperglycemia in shift workers. METHODOLOGY: 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. Hyperglycemia was classified when fasting glucose ≥100 mg/dL or HbA1c ≥ 5.7%. Data were compared using chi-square analysis with Cramer's V as effect size, and Bonferroni correction. Multivariate logistic regression, from a model of determination, was performed to investigate whether VDD was associated with hyperglycemia. RESULTS: The study evaluated 1411 workers, most workers were aged 30-39 years (53.2%), and 77.5% self-declared as black, brown, with up to complete high school (71.4%) and working alternate shifts for more than 5 years (76.1%). Regarding glucose and vitamin D, 32.0% and 29.1% of the workers had hyperglycemia and VDD, respectively. In multivariate analysis, controlled for confounding factors, workers with VDD had a 119% increased chance of hyperglycemia (OR: 2.19; IC95%: 1.56-3.08). Furthermore, vitamin D levels in distribution quintiles showed a dose-response gradient in relation to hyperglycemia, where increased vitamin D values were associated with a reduction in the occurrence of hyperglycemia. CONCLUSION: Rotating shift workers with vitamin D deficiency are more likely to have hyperglycemia.

Spatial clusters of diabetes: individual and neighborhood characteristics in the ELSA-Brasil cohort study.

This study identified spatial clusters of type 2 diabetes mellitus among participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) residing in two cities and verified individual and neighborhood socioeconomic environmental characteristics associated with the spatial clusters. A cross-sectional study was conducted with 4,335 participants. Type 2 diabetes mellitus was defined as fasting blood glucose ≥ 126mg/dL (7.0mmol/L), oral glucose tolerance test ≥ 200mg/dL (11.1mmol/L), or glycated hemoglobin ≥ 6.5% (48mmol/L); by antidiabetic drug use; or by the self-reported medical diagnosis of type 2 diabetes mellitus. Neighborhood socioeconomic characteristics were obtained from the 2011 Brazilian census. A spatial data analysis was conducted with the SaTScan method to detect spatial clusters. Logistic regression models were fitted to estimate the magnitude of associations. In total, 336 and 343 participants had type 2 diabetes mellitus in Belo Horizonte, Minas Gerais State (13.5%) and Salvador, Bahia State (18.5%), respectively. Two cluster areas showing a high chance of type 2 diabetes mellitus were identified in Belo Horizonte and Salvador. In both cities, participants living in the high type 2 diabetes mellitus cluster area were more likely to be mixed-race or black and have a low schooling level and manual work; these were also considered low-income areas. On the other hand, participants in the low type 2 diabetes mellitus cluster area of Salvador were less likely to be black and have low schooling level (university degree) and live in a low-income area. More vulnerable individual and neighborhood socioeconomic characteristics were associated with living in clusters of higher type 2 diabetes mellitus occurrence , whereas better contextual profiles were associated with clusters of lower prevalence.

The 30-year cardiovascular risk trajectories and their independently associated factors in participants of a Brazilian cohort (CUME Study) / As trajetórias de risco cardiovascular de 30 anos e seus fatores independentemente associados em participantes de uma coorte brasileira (Estudo CUME) / Las trayectorias de riesgo cardiovascular de 30 años y sus factores asociados de forma independiente en participantes de una cohorte brasileña (Estudio CUME)

Abstract: We aimed to analyze the different trajectories of 30-year cardiovascular risk (CVR) and its independently associated factors in participants of the CUME Study, a prospective study with alumni from federal universities of Minas Gerais State, Brazil. In this study, 1,286 participants who answered the baseline (2016) and follow-up (2018 and 2020) questionnaires were included. Trajectories of CVR, according to the Framingham score, were identified with the latent class growth modelling technique with the use of the censored normal model. Analysis of the factors independently associated with each of the trajectories was conducted with multinomial logistic regression technique. Three CVR trajectories were identified: Low-Low (68.3%), Medium-Medium (26.2%), and High-High (5.5%). Male sex, living in a stable union, and having moderate and high intakes of ultra-processed foods were positively associated with the Medium-Medium and High-High CVR trajectories. Having non-healthcare professional training and working were positively associated with the Medium-Medium CVR trajectory, whereas being physically active was negatively associated with the High-High CVR trajectory. In conclusion, more than one-third of participants had CVR trajectories in the Medium-Medium and High-High categories. Food consumption and physical activity are modifiable factors that were associated with these trajectories; thus, implementing health promotion measures could help prevent the persistence or worsen of CVR. On the other hand, sociodemographic and labor characteristics are non-modifiable factors that were associated with Medium-Medium and High-High trajectories, which could help identify people who should be monitored with more caution by health services.

Resumo: Nosso objetivo foi analisar as diferentes trajetórias de risco cardiovascular (RCV) de 30 anos e seus fatores independentemente associados em participantes do Estudo CUME, um estudo prospectivo com ex-alunos de universidades federais de Minas Gerais, Brasil. Este estudo incluiu 1.286 participantes que responderam aos questionários de linha de base (2016) e acompanhamento (2018 e 2020). As trajetórias de RCV, de acordo com o escore de Framingham, foram identificadas por modelagem de crescimento de classe latente com o uso do modelo normal censurado. A análise dos fatores independentemente associados a cada uma das trajetórias foi realizada por regressão logística multinomial. Foram identificadas três trajetórias de RCV: Baixo-Baixo (68,3%), Médio-Médio (26,2%) e Alto-Alto (5,5%). Sexo masculino, união estável e consumo moderado e alto de alimentos ultraprocessados foram positivamente associados às trajetórias de RCV Médio-Médio e Alto-Alto. Formação profissional e trabalhar em áreas não relacionadas à saúde foram positivamente associados à trajetória de RCV Médio-Médio, enquanto ser fisicamente ativo foi negativamente associado à trajetória de RCV Alto-Alto. Em conclusão, mais de um terço dos participantes apresentou trajetórias de RCV nas categorias Médio-Médio e Alto-Alto. Fatores modificáveis foram associados a essas trajetórias (consumo de alimentos e atividade física); assim, medidas de promoção da saúde podem evitar a manutenção ou a piora do RCV. Por outro lado, os fatores não modificáveis associados às trajetórias Médio-Médio e Alto-Alto (características sociodemográficas e laborais) permitem traçar o perfil das pessoas que devem ser monitoradas com mais cautela pelos serviços de saúde.

Cardiovascular Risk Factors in Haul Truck Operators of the Mining Sector Working a Rotational Schedule

Abstract Background: Due to the growing concern about work-related social and health aspects, occupational health and safety has become relevant. Objective: This work aims to develop a model to assist cardiovascular risk management in a team of haul truck operators, who work in rotating shifts at a mining company in Brazil. Methods: This longitudinal study evaluated risk factors for cardiovascular diseases of 191 mineworkers at three times points - 2010, 2012, and 2015. In addition, the risk of developing cardiovascular diseases was calculated, and the risk factors were analyzed using the chi-square test, the U Mann-Whitney test, and binary logistic regression. The significance level was set at 5%. Results: In the study period, body weight, body mass index (BMI), waist-to-height ratio (WHR), systolic (SBP), and diastolic blood pressure (DBP), total cholesterol, high-density lipoprotein cholesterol (HDL-C), and triglycerides levels of the study group increased. In 2015, there was a high prevalence of alcohol intake, overweight or obesity, central obesity, inadequate WHR, high blood pressure, total cholesterol above 190 mg/dL, and triglycerides above 150 mg/dL. An association was identified between increased cardiovascular risk and age, SBP, HDL-C, low-density lipoprotein cholesterol (LDL-C), and elevated glucose levels. Conclusion: Intense interventions for reduction and prevention of elevated alcohol intake, blood pressure levels, WHR, metabolic syndrome, blood glucose, and LDL-C levels, and low HDL-C levels are needed. In addition, a close monitoring of mine workers over 38 years of age who smoke, consume alcoholic beverages, and have altered blood glucose levels is important.

Built and social environments and overweight among Brazilian adults from medium-sized city: CUME Project.

A cross-sectional study enrolled participants from the CUME project (n = 289) who lived in Viçosa, Brazil. The neighborhood unit adopted was the buffer (200 meters), considering the participant's residence as central point. We measure the number of public and private facilities inside the buffer as well as violent criminal occurrences. Food establishments were categorized into establishments with predominant sale of natural or minimally processed foods, mixed establishments, and establishments with predominant sale of ultra-processed foods. Those who attended the face-to-face interview filled two scales of perception of the environment. Overall, 33.6% of participants reported overweight. We observed a higher concentration of individuals close to the central region of the city. Access to different establishments, food environments, and criminal occurrences differed between normal-weight and overweight individuals. The groups deferred in the perception of the location of squares, open public spaces, clubs, and soccer fields. The results indicate the association between environmental characteristics and overweight in Brazilian adults.

O acesso a diferentes estabelecimentos, ambientes alimentares e ocorrências criminais diferiram entre indivíduos com eutrofia e com excesso de peso. Os grupos diferiram na percepção da localização de praças, espaços públicos abertos, clubes e campos de futebol. Os resultados indicam a associação entre as características ambientais e o excesso de peso em adultos brasileiros.

Hipovitaminose D e índices glicêmicos em trabalhadores de turno alternante de empresa de mineração / Hypovitaminosis D and glycemic index in individuals working in rotate shifts of a mining company

Objetivo: Demonstrar a prevalência da hipovitaminose D em trabalhadores de turno de uma empresa de mineração e verificar se, nesta população, há correlação entre as variáveis glicêmicas (hemoglobina glicada e glicemia de jejum) e os níveis séricos de vitamina D. Métodos: Estudo transversal observacional realizado por 2 anos consecutivos com trabalhadores de turno. No primeiro ano, foram analisados os níveis séricos de vitamina D (25(OH)D) e glicemia de jejum, excluindo indivíduos que realizavam tratamento para controle glicêmico, suplementação de vitamina D e/ou participantes do sexo feminino, totalizando 548 trabalhadores. No ano seguinte, foram selecionados da amostra anterior apenas os indivíduos que apresentaram hipovitaminose D (25(OH) D<30ng/mL). Nestes, foram analisados os níveis de 25(OH)D, glicemia de jejum e hemoglobina glicada. Foram aplicados o teste de normalidade Kolmogorov-Smirnov e a correlação de Spearman. Resultados: A idade média dos participantes foi de 38,2 anos. No primeiro ano, 80,8% dos trabalhadores apresentaram hipovitaminose D e 10,8% apresentavam glicemia de jejum fora dos níveis de normalidade. Dentre a amostra do ano seguinte, 81,1% permaneceram com hipovitaminose D, 18,2% apresentaram glicemia de jejum fora dos níveis de normalidade e 15,8% apresentaramhemoglobina glicada alterada. Não foram encontradas correlações significativas entre a 25(OH)D e a glicemia de jejum e hemoglobina glicada. Conclusão: Foi observada alta prevalência de hipovitaminose nos trabalhadores de turno. Diferentemente de outros estudos, não foram encontradas correlações significativas entre as variáveis glicêmicas e a concentração sérica da vitamina D. (AU)

Objective: To demonstrate the prevalence of hypovitaminosis D in shift workers of a mining company, and to check whether, in this population, there is a correlation between glycemic variables (glycosylated hemoglobin and fasting plasma glucose)- and serum levels of vitamin D. Methods: These are cross-sectional observational studies performed in two consecutive years with shift workers. In the first year, the serum levels of vitamin D (25(OH)D) and fasting plasma glucose were analyzed, with people who underwent treatment for glycemic control, vitamin D supplementation, and/or female participants being excluded, totalizing 548 workers. In the following year, only those individuals who presented hypovitaminosis D (25 (OH) D <30 ng/dL) were selected from the previous sample. The levels of 25 (OH) D, fasting plasma glucose, and HbA1C of these individuals were analyzed. The Kolmorogov-Smirnov normality test and the Spearman correlation were applied. Results: Th e m ean a ge o f participants was 38.2 years. In the first year, 80.8% (n=442) of the workers presented hypovitaminosis D, and 10.8% had fasting plasma glucose out of normal levels. Among the sample of the following year, 81.1% remained with hypovitaminosis D, 18.2% (n=51) had fasting glycemia out of normal levels, and 15.8% (n=44) had altered glycosylated hemoglobin. Conclusion: A high prevalence of hypovitaminosis in shift workers was observed. Differently from other studies, no significant correlations were found between glycemic variables and serum vitamin D concentration. (AU)

Indicadores de adiposidade como método de rastreamento para polissonografia em trabalhadores de turno / Adiposity indicators as a screening method for polysomnography in shift workers

Resumo Objetivo: verificar o potencial discriminatório dos indicadores de adiposidade na predição da apneia obstrutiva do sono (AOS) em trabalhadores de turnos. Métodos: estudo transversal realizado em uma empresa de extração de minério de ferro, em Minas Gerais, Brasil. Dados antropométricos foram coletados e polissonografia (PSG) foi realizada em 118 trabalhadores de turno do sexo masculino que possuíam ao menos um fator de risco global para doença cardiovascular. Resultados: a prevalência de AOS na amostra foi de 84,7%. Entre os indicadores de adiposidade usados para predizerem a AOS (≥ 5 eventos/hora), o índice de massa corporal (IMC), a circunferência da cintura (CC), a relação cintura/estatura (RCE) e a gordura corporal total (GCT), revelaram valores de sensibilidade acima de 70%. Gordura visceral (GV), circunferência do pescoço (CP) e relação pescoço-estatura (RPE) foram as mais efetivas em identificar corretamente trabalhadores sem AOS (valores de especificidade acima de 70%). As áreas sob a curva de Característica de Operação do Receptor (COR) para CC e RPE foram maiores que 0,7, o que indicou que o teste foi eficaz na discriminação de indivíduos com AOS. Conclusões: alterações nos indicadores de adiposidade abdominal e cervical têm relação significativa com a presença de AOS e demostraram eficácia como método de rastreamento para PSG. CC e RPE são considerados bons indicadores para predizerem a AOS.

Abstract Objective: to verify the discriminatory power of adiposity indicators in the prediction of obstructive sleep apnoea (OSA) in shift workers. Methods: a cross-sectional 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.

Qualidade de vida e excesso de peso em trabalhadores em turnos alternantes / Quality of life and overweight in alternating shift workers

Resumo Objetivo: identificar a percepção dos trabalhadores de turnos alternantes de uma mineradora da região dos Inconfidentes, Minas Gerais, sobre sua qualidade de vida (QV) e analisar sua associação com indicadores de excesso de adiposidade corporal. Métodos: estudo transversal com 437 trabalhadores em turnos alternantes com um ou mais fatores de risco cardiovascular. Dados sociodemográficos e clínicos foram analisados. A QV foi avaliada com o questionário SF-36 e a adiposidade corporal estimada a partir das medidas antropométricas e de composição corporal. Resultados: a pontuação para os domínios da QV variou de 67 a 100, no entanto, o aumento de gordura corporal apresentou correlação negativa com os domínios saúde geral, vitalidade e capacidade funcional. Foi observada, por análise de cluster, a formação de dois agrupamentos, um composto pelos domínios da QV e o outro constituído pelos indicadores de composição corporal. Não foi identificada associação entre os escores estimados de QV dos trabalhadores de turno e o tempo de trabalho. Conclusão: o declínio da QV apresentou associação com o excesso de adiposidade corporal. Recomenda-se a adoção de medidas visando reduzir o excesso de adiposidade corporal e melhorar a qualidade de vida dos trabalhadores em turno alternante da mineração.

Abstract Objective: to identify the perception that alternating shift workers from a mining company in the region of Inconfidentes, Minas Gerais, Brazil, have about their quality of life (QoL) and to analyse its association with indicators of excess body adiposity. Methods: cross-sectional study involving 437 alternating shift workers with one or more cardiovascular risk factors. Sociodemographic and clinical data were analyzed. QoL was evaluated by the SF-36 questionnaire. Body adiposity was estimated through anthropometric and body composition measurements. Results: the scores for QoL domains ranged from 67 to 100, however, body fat increasing showed a negative correlation with general health, vitality and functional capacity domains. Through cluster analysis, the authors observed the formation of two groups, one comprising the QoL domains, and a second made up of body composition indicators. No association was found between the shift workers estimated QoL scores and their shift working lifetime. Conclusion: the QoL decline was associated with body adiposity excess. The recommendation is the adoption of measures aimed at reducing excess body adiposity and improving mining alternating shift workers' quality of life.

Resistin and visfatin concentrations are related to central obesity and inflammation in Brazilian children

Background:The evidence that cardiovascular disease begins in childhood and adolescence, especially in the presence of excess weight, is associated with dysfunction on adipokine pro-inflammatory secretion. These affect glucose metabolism and lead to other complications related to insulin resistance and cardiovascular disease. This study assessed the association of anthropometric and metabolic parameters related to obesity, cardiovascular risk,and insulin resistance with concentrations of resistin and visfatin, in children. Methods: A cross-sectional study was developed with 178 children of 6­10 years old enrolled in public city schools. Anthropometric data, composition body, clinical, and biochemical were measured according to standard procedures. We used multiple regression models by stepwise method to evaluate the associations of resistin and visfatin with variables of interest.RESULTS: In healthy weight children, resistin was associated with LDL cholesterol, visfatin, atherogenic index, andwaist-to-height ratio, whereas in obese children resistin was associated with visfatin and interaction between conicity index and HOMA-AD. Furthermore, in healthy weight children, visfatin was associated to resistin and triceps skinfold thickness and negatively associated to HOMA-AD, while in obese ones visfatin was associated with waist-to-height ratio, atherogenic index, resistin, and interaction between trunk adiposity index and adiponectin and wasnegatively associated with the HOMA-IR index.CONCLUSIONS:Our study shows an association between anthropometric and biochemical variables related tovisceral fat and inflammation. These results suggest the resistin and visfatin as good pro-inflammatory markers. In addition, both adipokines are strongly related to central obesity, in children. In addition, both adipokines are strongly related to central obesity, in children.

Alta exigência no trabalho e alto risco cardiovascular em funcionários de uma universidade pública / Alta demanda en el trabajo y alto riesgo cardiovascular en funcionarios de una universidad pública / High demand at work and high cardiovascular risk in employees of a public university

Objetivo: estimar a associação entre a alta exigência no trabalho e o elevado risco cardiovascular. Métodos: estudo epidemiológico transversal, desenvolvido com 211 trabalhadores do campus saúde de uma universidade pública do Estado de Minas Gerais. A alta exigência no trabalho foi definida com base no modelo demanda-controle de Karasek, enquanto o elevado risco cardiovascular, a partir do escore de Framingham. A associação entre a alta exigência no trabalho e o elevado risco cardiovascular foi estimada pela Razão de Prevalência (RP) e seu Intervalo de Confiança de 95% (IC 95%), ajustada por potenciais fatores de confusão e calculada por meio da regressão de Poisson. Resultados: a alta exigência no trabalho e o elevado risco cardiovascular estavam presentes em28,4% e 28,0% dos participantes. Após a análise multivariada, a alta exigência no trabalho manteve-se associada ao elevado risco cardiovascular (RP = 3,67; IC 95%: 1,40-9,59). Conclusão: a prevalência do elevado risco cardiovascular foi alta nos trabalhadores expostos ao estresse psicoemocional no ambiente de trabalho. Portanto, esse achado deve ser considerado nas discussões sobre melhoria da qualidade de vida e na promoção da saúde dos trabalhadores com modificações no processo e nas relações de trabalho.

Objective: to estimate the association between job strain and high cardiovascular risk. Methods: this was a cross-sectional epidemiologicalstudy developed with 211 employees in the health field of a public university in Minas Gerais State, Brazil. The job strain was definedaccording to the Karasek demand-control model while the risk of high cardiovascular issues was based on the Framingham score. Therelationship between job strain and high cardiovascular risk was estimated using the Prevalence Ratio (PR) and its 95% Confidence Interval(95% CI), adjusted for potential confounding factors, and calculated through the Poisson regression. Results: job strain and highcardiovascular risk were present in 28.4% and 28.0% of participants, respectively. After the multivariate analysis, job strain remainedindependently associated with high cardiovascular risk (PR = 3.67; 95% CI: 1.40-9.59). Conclusions: the prevalence of elevatedcardiovascular risk was high among workers exposed to psycho-emotional stress in the workplace. This finding should be considered innew policies regarding the workers’ quality of life and health promotion that may culminate with changes in labor relationships.
