RESUMO
OBJECTIVE: The objective of our study was to explore the association between sleep deprivation and obesity among shift workers. DESIGN: A cross-sectional study was conducted. Obesity was defined as BMI ≥30 kg/m2. Time of sleep was categorized as: >5 h of continuous sleep/d; ≤5 h of continuous sleep/d with some additional rest (sleep deprivation level I); and ≤5 h of continuous sleep/d without any additional rest (sleep deprivation level II). Sociodemographic, parental and behavioural variables were evaluated by means of a standardized pre-tested questionnaire. Potential confounding factors were controlled for in the multivariable model. SETTING: A poultry-processing plant in southern Brazil. SUBJECTS: Nine hundred and five shift workers (63 % female). RESULTS: Obesity was more prevalent in the participants who were female, aged 40 years and older, who had less schooling and reported excess weight in both parents. Sleep deprivation levels I and II were associated with increased income, number of meals consumed throughout the day and nightshift work. All of the workers who exhibited a degree of sleep deprivation worked the night shift. After controlling for potential confounding factors, the prevalence ratios of obesity were 1·4 (95 % CI 0·8, 2·2) and 4·4 (95 % CI 2·4, 8·0) in the workers with sleep deprivation levels I and II, respectively, compared with the reference group. CONCLUSIONS: These results show a strong association between sleep deprivation and obesity in shift workers and that sleep deprivation may be a direct consequence of working at night.

Our objective was to estimate the prevalence and test the association between psychological well-being and overweight in children. We conducted a cross-sectional study using anthropometrical measures and interviews with 1048 6-10-year-old school children from a Brazilian town. Overweight was assessed by the body mass index and included obesity. Psychological data of children and their parents were collected using a face scale. Poisson regression models were used to test the associations and to obtain unadjusted and adjusted prevalence ratios (PR). The prevalence of overweight was of 15.3% (95% CI: 13.2-17.6) and of only obesity was 3.8% (2.8-5.2). After controlling for age, sex, school type and parental overweight, the prevalence of overweight was 52% and 44% higher in children who reported a psychological dissatisfaction in themselves and in their mothers when compared with those with positive self perception (PR = 1.52 95% CI = 1.02-2.28; P = 0.038) and (PR = 1.44 95% CI = 1.00-2.09; P = 0.049), respectively. The study suggests that actions aiming weight control of children should take into account psychological aspects of children and their families.

BACKGROUND AND AIMS: Multimorbidity is a common health condition, and the relationship between different patterns of multimorbidity and food consumption through dietary patterns needs to be determined. This study aimed to investigate the association between dietary patterns and multimorbidity patterns in women. METHODS: This population-based cross-sectional study included 1128 women (aged 20-69 years) living in southern Brazil. We identified multimorbidity patterns using principal component analysis, and the main exposure of the study was three dietary patterns, as derived in a previous study: healthy, risk, and Brazilian patterns. Using Poisson regression with robust variance, the scores of multimorbidity patterns (high/low) were evaluated using different adjustment models. RESULTS: Three patterns of multimorbidity were derived: cardiometabolic (dyslipidemia, circulatory disorders, hypertension, diabetes), endocrine-articular (thyroid diseases, osteoporosis/osteopenia, rheumatic diseases), and psychosomatic (chronic pain, common mental disorders, acid-related digestive disorders). In the relationship between the dietary patterns and multimorbidity patterns, after adjustment, it was observed that a greater adherence to the Brazilian dietary pattern was associated with a lower probability of a high score for the cardiometabolic pattern (PR = 0.68; 95% CI: 0.51-0.89) and psychosomatic pattern (PR = 0.63; 95% CI: 0.47-0.84). Greater adherence to the healthy dietary pattern was associated with a higher probability of a high score for the cardiometabolic pattern (PR = 1.69; 95% CI: 1.27-2.25) and endocrine-articular pattern (PR = 2.05; 95% CI: 1.39-3.02). The risk dietary pattern did not demonstrate an association after adjustment was implemented. CONCLUSIONS: This study provides the first evidence of an association between dietary patterns and multimorbidity patterns. Greater adherence to the Brazilian dietary pattern was a protective factor for a high score for the cardiometabolic and psychosomatic pattern in women. Dietary orientation should be considered in guidelines related to multimorbidity, constituting part of the prevention and management strategies for this condition.

OBJECTIVE: This study aimed to investigate the association between dietary patterns and prevalence of multimorbidity in women. METHODS: This population-based cross-sectional study was conducted in 2015 and included 1,128 women aged 20 to 69 years living in the urban area of São Leopoldo municipality, southern Brazil. Multimorbidity was defined as the presence of two or more chronic conditions, among the 26 identified. Poisson regression with robust variance was used to investigate the association between the three dietary patterns (healthy, risk, and Brazilian), using different models adjusted for sociodemographic, behavioral, and nutritional status variables. RESULTS: The results showed differences in the prevalence of adherence to different dietary patterns and multimorbidity across age groups, with a prevalence of multimorbidity and a healthy dietary pattern showing a direct linear trend with age, whereas the risk dietary pattern showed an inverse linear trend with age. The prevalence of the Brazilian dietary pattern remained constant despite differences in age. After adjustment, we found that women with greater adherence to the Brazilian dietary pattern showed a 40% reduction in the prevalence of multimorbidity compared with those with less adherence (prevalence ratio, 0.60; 95% confidence interval, 0.40-0.86). CONCLUSION: The results revealed that the prevalence of multimorbidity was significantly lower in women with greater adherence to the Brazilian dietary pattern and highlight the importance of dietary interventions in early adulthood as a way to prevent multimorbidity in women.

OBJECTIVE: Assess serum 25-hydroxyvitamin D (25OHD) concentration and associated factors among users of a referral outpatient unit for vascular diseases in Southern Brazil. DESIGN: Cross-sectional study conducted for almost one year, from March 2016 to January 2017. The serum vitamin D level was determined biochemically and classified as: sufficient (>50 nmol/L), insufficient (30-50 nmol/L) and deficient (<30 nmol/L). Associations were tested through multiple linear regression. SETTING: At a reference outpatient clinic specialized in vascular diseases located in a southern Brazilian medium-sized city (latitude 29°S). SUBJECTS: Consecutive sample of 133 individuals of both sexes, aged at least 40 years. RESULTS: The mean serum 25OHD concentration was 54.9 ± 25.9 nmol/L (57.7 ± 27.9 nmol/L for men; 52.2 ± 24.2 nmol/L for women, p = 0.267). A total of 12.8% of the participants had vitamin D deficiency and 32.3% had insufficiency. Regarding the total sample, variables associated to the serum 25OHD concentration were: age (ß = -0.55; CI95% -0.95; -0.17), sun exposure (ß = 1.22; CI95% 0.32; 2.10) and vitamin D intake (ß = 7.29; CI95% 2.10; 12.48). Among men, a significant association was observed for age (ß = -0.82; CI95% -1.47; -0.17, p = 0.015) and borderline for sun exposure (ß = 1.22; CI95% 0.32; 2.10, p = 0.053). Among women, only vitamin D intake was significantly associated with serum concentration of this vitamin (ß = 8.74; CI95% 1.32; 16.17, p = 0.022). CONCLUSION: Although the mean 25OHD concentration was greater than 50 nmol/L, about 45% of this consecutive sample presented poor vitamin D nutritional status. Unadjusted for seasonality, factors associated with serum 25OHD concentration were age and sun exposure among men and vitamin D intake among women.

OBJECTIVE: To investigate the association between low serum vitamin D levels and peripheral arterial disease (PAD). METHODS: A cross-sectional study with a consecutive sample of 133 individuals from Caxias do Sul, Brasil. We considered PAD patients those with an ankle-brachial index (ABI) ≤ 0.90 or with arterial revascularization. Vitamin D serum level was categorized as sufficient (≥30 ng/mL), insufficient (>20 to 29 ng/mL), and deficient (<20 ng/mL). Prevalence ratios (RP) were calculated through Poisson regression. RESULTS: The prevalence of PAD was 50.7% (95% CI 42-59). After adjustment for potential PAD risk factors, RP were 1.08 (95% CI 0.66-1.76) for insufficient serum level and 1.57 (95% CI 0.96-2.57) for deficient vitamin D serum level; (p for trend = 0.020). CONCLUSION: Vitamin D serum levels showed an inverse and significant dose-response relationship with PAD.

The aim of this study was to describe sedentary behavior (SB) across leisure, occupation, and transport domains and determine factors associated with excessive sedentary behavior (ESB). Cross-sectional survey with a representative sample of 1,126 women aged 20-69 years living in São Leopoldo/RS. SB, demographic, socioeconomic, behavioral and health factors data were collected using a questionnaire administered by interviewers. The cut-off point for ESB was defined as the median. Associations were tested using Poisson regression with robust error variance. The medians and interquartile intervals (min/day) for leisure, occupation, and transport SB were 163.9(86.6-2710.5), 51.4(0-257.1), and 17.1(5.7-37.3), respectively. The likelihood of leisure SB increased with education level, was higher among women who were not employed, lived in household without children, and smokers. In other domains, there was an inverse association between age, being white, economic class, education level, and income and ESB. Direct association between living in a household with a car and excessive transport SB and women who were not employed were 30% less likely to engage in ESB in this domain. The predominant domain in Total SB was leisure. Associations differed across domains, indicating that domain-specific interventions should be implemented in addressing excessive SB.
O objetivo deste estudo foi descrever o comportamento sedentário (CS) nos domínios lazer, ocupação e deslocamento e verificar fatores associados ao excesso deste comportamento (ECS). Estudo transversal, com amostra representativa de 1.126 mulheres, 20-69 anos, de São Leopoldo/RS. CS, variáveis demográficas, socioeconômicas, comportamentais e relacionada à saúde foram avaliados através de questionário, aplicado em forma de entrevista. Considerou-se ECS valores acima da mediana. Utilizou-se regressão de Poisson com variância robusta. As medianas e intervalos interquartílicos (min/dia), para o CS no lazer, ocupação e deslocamento foram, respectivamente, 163,9 (86,6-2710,5), 51,4 (0-257,1) e 17,1 (5,7-37,3). A probabilidade do ECS no lazer aumentou com a escolaridade, foi maior entre as mulheres que não trabalhavam, sem crianças em casa e fumantes. Nos demais domínios, a probabilidade aumentou inversamente com a idade, foi maior entre mulheres brancas e aumentou com a classe econômica, escolaridade e renda. A probabilidade de ECS no deslocamento também aumentou com o número de carros no domicílio e foi 30% menor entre mulheres que não trabalhavam. O maior tempo de CS observado foi no domínio do lazer. As associações diferiram segundo o domínio, indicando distintas intervenções.

INTRODUCTION: Dietary patterns may be more predictive of disease risk than individual nutrients or foods. OBJECTIVE: To identify dietary patterns and associated factors among adult women. METHOD: Population-based cross-sectional study with 1,128 women, aged 20 to 69 years, living in São Leopoldo, Rio Grande do Sul. Food intake was assessed with a frequency questionnaire. The principal component analysis identified dietary patterns. We estimated crude and adjusted prevalence ratios using Poisson regression with robust variance. RESULTS: Threedietary patterns - responsible for 25.8% of the total variance - were identified: healthy (fruits, vegetables, and whole foods); risk (ultra-processed foods); and Brazilian (rice and beans). The healthy pattern showed the largest percentage of explained variation (11.62%). The probability of adherence to the healthy pattern increased linearly with age and schooling and was higher among ex-smokers [prevalence ratio (PR)=1.22; confidence interval of 95% (95%CI) 1.04 - 1.42]. Younger women and those with better schooling had more chances of adhering to the risk pattern. The probability of adherence to the Brazilian pattern increased as schooling decreased and was higher among non-white women (PR = 1.29; 95%CI 1.04- 1.59). CONCLUSIONS: While adherence to healthy and risk patterns behaved differently according to women's age, it was similar regarding schooling. Socioeconomic conditions defined adherence to the Brazilian pattern.
INTRODUÇÃO: Padrões alimentares parecem predizer melhor o risco de doenças do que nutrientes ou alimentos isoladamente. OBJETIVO: Identificar padrões alimentares e fatores associados em mulheres adultas. MÉTODO: Estudo transversal, de base populacional, com 1.128mulheres, de 20 a 69 anos de idade, de São Leopoldo, Rio Grande do Sul. O consumo alimentar foi avaliado por meio de um questionário de frequência. Utilizou-se análise de componentes principais para identificação dos padrões alimentares. Razõesde prevalências brutas e ajustadas foram estimadas por meio de regressão de Poisson com variância robusta. RESULTADOS: Foram identificados três padrões alimentares que explicaram 25,8% da variância total: saudável (frutas, vegetais e alimentos integrais); de risco (alimentos ultraprocessados); e brasileiro (arroz e feijão). Opadrão saudável apresentou o maior percentual de variância explicada (11,62%). A probabilidade de adesão ao padrão saudável aumentou linearmente com a idade e a escolaridade e foi maior em ex-fumantes (razão de prevalência - RP = 1,22; intervalo de 95% de confiança (IC95%) 1,04 - 1,42). Já mulheres mais jovens e com maior escolaridade tinham maior probabilidade de aderir ao padrão de risco. A probabilidade de adesão ao padrão brasileiro aumentou à medida que diminuiu a escolaridade e foi maior em mulheres de cor de pele não branca (RP = 1,29; IC95% 1,04 - 1,59). CONCLUSÕES: Enquanto a adesão aos padrões saudável e de risco comportou-se distintamente segundo a idade das mulheres, ela foi semelhante para a escolaridade. Já a adesão ao padrão brasileiro foi definida pelas condições socioeconômicas.

OBJECTIVES: To assess the association between neighbourhood environmental variables and excessive transport-related and leisure-time sedentary behaviour (ETSB and ELSB, respectively) amongst adult women in Southern Brazil. METHODS: A cross-sectional survey was conducted using a representative sample of 1079 women 20 to 69 years of age who lived in 44 neighbourhoods. Each neighbourhood was determined by drawing a 400-m buffer around the median point of the participants' homes. Neighbourhoods were assessed by audit and by using government data. Sedentary behaviour (SB) and the remaining individual variables were assessed via questionnaire that was administered as an interview. Multilevel logistic regression analysis was conducted. RESULTS: In the adjusted analysis, women who lived in neighbourhoods with a higher percentage of terrain slope and fewer public recreation areas per resident had significantly (p ≤ 0.05) increased odds of exhibiting ETSB and ELSB, with 50% and 40% increases, respectively. CONCLUSIONS: The results show that some aspects of the neighbourhood environment such as terrain slope and total public recreation areas per resident are related to specific SBs, indicating that improvements in neighbourhoods can reduce SB in women.

BACKGROUND: Musculoskeletal pain is one of the most common occupational problems in the industrial society and its prevalence is potentially associated with mental disorders. OBJECTIVE: To estimate the prevalence of work-related musculoskeletal pain and its association with occurrence of common mental disorders among employees of a poultry processing company in Southern Brazil. METHODS: Cross-sectional study conducted in 2010 with 1,103 employees aged 18 to 52 years old. Musculoskeletal pain was investigated based on a human figure adapted from the Standardized Nordic Questionnaire. We considered reported work-related pain in any part of the body in the past 12 months. Occurrence of common mental disorders was assessed- by the Self-Reporting Questionnaire (SRQ-20). Crude and adjusted prevalence ratios (PR) and corresponding 95% confidence interval (95%CI) were obtained by Poisson regression with robust variance. RESULTS: The prevalence of work-related musculoskeletal pain was 40.3% (95%CI 37.4-43.2) for the total sample, 46.8% (95%CI 43.2-50.5) for women and 27.8% (95%CI 23.2-32.3) for men. The prevalence of musculoskeletal pain was twice higher for the participants with common mental disorders compared to those without this condition (PR=2.27; 95%CI 1.99-2.58). This effect remained significant after adjustment for sociodemographic, behavioral, health-related and occupational variables. CONCLUSION: The results of the present study point to the relevance of preventive measures to promote the mental and physical health of workers in order to reduce or minimize the occurrence of pain.
CONTEXTO: A dor musculoesquelética é um dos problemas ocupacionais mais comuns nas sociedades industrializadas, e sua prevalência é potencialmente associada à presença de transtornos mentais. OBJETIVO: Estimar a prevalência de dor musculoesquelética relacionada ao trabalho e sua associação com a presença de transtornos mentais comuns em trabalhadores de um frigorífico do Sul do Brasil. MÉTODOS: Realizou-se um estudo transversal com o total de 1.103 trabalhadores, de 18 a 52 anos de idade, em 2010. A dor musculoesquelética foi avaliada por meio de uma figura humana adaptada do Questionário Nórdico de Sintomas Osteomusculares. Considerou-se o relato da presença de dor relacionada ao trabalho em qualquer região do corpo nos últimos 12 meses. A presença de transtornos mentais comuns foi determinada pelo Self-Reporting Questionnaire (SRQ-20). Razões de prevalências (RP) brutas e ajustadas, com seus respectivos intervalos de confiança de 95% (IC95%), foram obtidas mediante a regressão de Poisson. RESULTADOS: A prevalência de dor musculoesquelética relacionada ao trabalho foi de 40,3% (IC95% 37,4-43,2) na amostra geral, 46,8% (IC95% 43,2-50,5) nas mulheres e 27,8% (IC95% 23,2-32,3) nos homens. Na análise bruta, trabalhadores com presença de transtornos mentais comuns apresentaram prevalência duas vezes maior de dor musculoesquelética relacionada ao trabalho quando comparados com aqueles sem transtornos (RP=2,27; IC95% 1,99-2,58). Esse efeito manteve-se significativo após o ajuste para variáveis sociodemográficas, comportamentais, de saúde e ocupacionais. CONCLUSÃO: Os resultados deste estudo alertam para a importância de medidas visando à promoção da saúde física e mental dos trabalhadores em ações para reduzir a dor.
RESUMO
The aim of this study was to explore the association between sleep-related problems with the occurrence of minor psychiatric disorders in shift workers of southern Brazil. A cross-sectional study with 1202 workers (785 females) aged 18-50 years was carried out. Minor psychiatric disorders were assessed using the Self-Reporting Questionnaire (SRQ-20), and four sleep problems were collected and analyzed: sleep deprivation (≤ 5h), difficulty falling asleep, waking up during sleep, and sleep medication use. Results show that the overall prevalence of minor psychiatric disorders was 26.8%, but it was more prevalent among females than males (30.2% vs. 20.4%). Nightshift work was significantly associated with the occurrence of sleep-related problems. After adjusting for confounding factors, the number of sleep-related problems showed a positive linear trend with psychiatric disorders in both sexes. Having two or more sleep-related problems was associated with increased probability of psychiatric disorders approximately three-fold among males and two-fold among females, when compared with those without sleep problems. In conclusion, this study demonstrated that sleep-related problems have a strong and independent association with psychiatric disorders among shift workers. Furthermore, the prevalence of both conditions was higher among females than males; however, the strength of these associations was higher in males.

This research involves a school-based cross sectional study to evaluate the association between food insecurity (FI) and inadequate food intake (IFI), among 782 children (mean age of 6.9±0.5) of the 1st year of primary school in the municipal schools of São Leopoldo in the state of Rio Grande do Sul. Data were gathered from mothers or guardians. FI was obtained through the Brazilian Food Insecurity Scale, and food consumption using the food frequency questionnaire. Foods were classified as healthy eating markers (HEM) and unhealthy (UEM) and received scores according to intake frequency. HEM: 0 - 1 day - zero; 2 to 3 days - 0.25; 4 to 5 days - 0.75; 6 to 7 days - 1, and the reverse for the UEM. The scores could range from 0 to 25 (HEMS) and 0 to 19 (UEMS). A standardized total score (TS) was obtained [HEMS * (19/44) + UEMS * (25/44)] and could range from 0 to 22. The scores were categorized into terciles and the 1st considered IFI. The FI was 45.1% and the average scores were 5.9 (HEMS), 15.9 (UEMS) and 11.6 (TS). No association was found between IA and IFI. High IA and low food scores require intersectoral approaches to ensure access to food in quantity and quality appropriate for this population.

BACKGROUND: Diabetes has been shown to be associated with increased mortality and morbidity worldwide. This study explored whether diabetes significantly impacts on outcomes among elderly adults with cardiovascular disease (CVD) admitted to a specialist hospital in Southern Brazil. DESIGN: A prospective cohort study of 411 patients admitted to hospital after a cardiac event between 2008 and 2010. METHODS: The primary end point was death by all causes during the follow up period of 6 months from admission. All hospital death reports matched those reported by the Brazilian Public Health Death Records. Cumulative probability of survival by Kaplan-Meier plot and log rank tests compared hospital admissions with or without diabetes. Adjusted and unadjusted hazard ratios (HR) for overall mortality were calculated. RESULTS AND CONCLUSIONS: The mean ± SD age of the subjects was 69.8 years ± 14 and 50% were men. Overall study mortality was 8.7%. Half of the deaths occurred in patients ≥80 years (p=0.001). Diabetes was associated with 53% of the overall mortality (p<0.01) and 79% of the CVD-related deaths (p<0.03). The adjusted HR was 2.88 (95% CI 1.42-5.84) for diabetic patients aged ≥80 years. In conclusion, the results suggest that elderly patients of European origin with diabetes residing in Southern Brazil admitted to hospital for specialist CVD treatment have poorer survival and higher risk of further CVD events 6 months after hospital discharge compared with those without. We recommend that better strategies for managing CVD risk factors among elderly diabetic patients from similar patient cohorts in Brazil are necessary.

Abstract Objectives: to identify dietary patterns (DP) and associated factors in first grade school-children in elementary schools in the South of Brazil. Methods: school-based cross-sectional study, with a non-probabilistic sample of 782 schoolchildren aged 6 to 8. Food intake was assessed by a food frequency questionnaire. DP were identified using the principal component analysis and the prevalence ratios were obtained by Poisson regression with a robust variance. Results: four DP were identified and accounted for 25.3% of the total variance: "fruit, vegetables and fish" (8.5%), "sweets and salty snacks" (7.0%), "dairy, ham and biscuits" (5.0%) and "common Brazilian food" (4.8%). After the adjustment, breakfast habit and lower frequency of meals in front of a screen increased the probability of adherence to a high consumption of DP of "fruit, vegetables and fish". The maternal schooling level was linearly and inversely associated with DP of "sweets and salty snacks" and "common Brazilian food", and positively related to the DP of "dairy, ham and biscuits". Schoolchildren with food inse-curity and sufficiently active had higher probability of adherence to DP of "common Brazilian food". Conclusions: four DP were identified and associated with food insecurity, maternal socioeconomic characteristics and schoolchildren's behavioral characteristics.
Resumo Objetivos: identificar padrões alimentares (PA) e fatores associados em escolares do primeiro ano do ensino fundamental de escolas municipais do sul do Brasil. Métodos: estudo transversal, de base escolar, com uma amostra não-probabilística de 782 escolares, de 6 a 8 anos. A ingestão alimentar foi avaliada por questionário de frequência alimentar. Os PA foram identificados através da análise de componentes princi-pais e razões de prevalência foram obtidas por regressão de Poisson com variância robusta. Resultados: foram identificados quatro PA que explicaram 25.3% da variância total: "frutas, verduras e peixe" (8,5%), "doces e salgadinhos" (7.0%); "laticínios, presunto e biscoitos" (5.0%) e "comum brasileiro" (4.8%). Após ajuste, hábito de realizar desjejum e baixa frequência de refeições em frente à tela aumentaram a probabilidade de adesão ao consumo elevado do PA "frutas, verduras e peixe". Escolaridade materna associou-se linear-mente e inversamente com o PA "doces e salgadinhos" e "comum brasileiro", e positiva-mente com o PA "laticínios, presunto e biscoitos". Escolares com insegurança alimentar e suficientemente ativos apresentaram maior probabilidade de adesão ao PA "comum brasileiro". Conclusões: identificaram-se quatro PA e foram observadas associações com insegu-rança alimentar, características socioeconômicas maternas e características comportamen-tais dos escolares.

OBJECTIVE To analyze if metabolic syndrome and its altered components are associated with demographic, socioeconomic and behavioral factors in fixed-shift workers. METHODS A cross-sectional study was conducted on a sample of 902 shift workers of both sexes in a poultry processing plant in Southern Brazil in 2010. The diagnosis of metabolic syndrome was determined according to the recommendations from Harmonizing the Metabolic Syndrome. Its frequency was evaluated according to the demographic (sex, skin color, age and marital status), socioeconomic (educational level, income and work shift), and behavioral characteristics (smoking, alcohol intake, leisure time physical activity, number of meals and sleep duration) of the sample. The multivariate analysis followed a theoretical framework for identifying metabolic syndrome in fixed-shift workers. RESULTS The prevalence of metabolic syndrome in the sample was 9.3% (95%CI 7.4;11.2). The most frequently altered component was waist circumference (PR 48.4%; 95%CI 45.5;51.2), followed by high-density lipoprotein. Work shift was not associated with metabolic syndrome and its altered components. After adjustment, the prevalence of metabolic syndrome was positively associated with women (PR 2.16; 95%CI 1.28;3.64), workers aged over 40 years (PR 3.90; 95%CI 1.78;8.93) and those who reported sleeping five hours or less per day (PR 1.70; 95%CI 1.09;2.24). On the other hand, metabolic syndrome was inversely associated with educational level and having more than three meals per day (PR 0.43; 95%CI 0.26;0.73). CONCLUSIONS Being female, older and deprived of sleep are probable risk factors for metabolic syndrome, whereas higher educational level and higher number of meals per day are protective factors for metabolic syndrome in fixed-shift workers.

SUMMARY OBJECTIVE To investigate the association between low serum vitamin D levels and peripheral arterial disease (PAD). METHODS A cross-sectional study with a consecutive sample of 133 individuals from Caxias do Sul, Brasil. We considered PAD patients those with an ankle-brachial index (ABI) ≤ 0.90 or with arterial revascularization. Vitamin D serum level was categorized as sufficient (≥30 ng/mL), insufficient (>20 to 29 ng/mL), and deficient (<20 ng/mL). Prevalence ratios (RP) were calculated through Poisson regression. RESULTS The prevalence of PAD was 50.7% (95% CI 42-59). After adjustment for potential PAD risk factors, RP were 1.08 (95% CI 0.66-1.76) for insufficient serum level and 1.57 (95% CI 0.96-2.57) for deficient vitamin D serum level; (p for trend = 0.020). CONCLUSION Vitamin D serum levels showed an inverse and significant dose-response relationship with PAD.
RESUMO OBJETIVO Investigar a associação entre níveis séricos de vitamina D e doença arterial obstrutiva periférica (DAOP). MÉTODOS Estudo transversal, com amostra consecutiva de 133 indivíduos. Foram considerados com DAOP pacientes com índice tornozelo braquial ≤ 0,90 ou com revascularização arterial. O nível sérico de vitamina D foi classificado em: suficiente (≥30 ng/mL), insuficiente (>20 a 29 ng/mL) e deficiente (<20 ng/mL). Razões de Prevalência (RP) foram calculadas por meio de regressão de Poisson. RESULTADOS A prevalência de DAOP foi de 50,7% (IC95% 42-59). Após ajuste para potenciais fatores de risco para DAOP, as RP foram de 1,08 (IC95% 0,66-1,76) para nível sérico insuficiente e de 1,57 (IC95% 0,96-2,57) para o nível sérico deficiente de vitamina D; (p para tendência = 0,020). CONCLUSÃO O nível sérico de vitamina D mostrou uma relação dose/resposta inversa e significativa com DAOP.

This cross-sectional school-based study in São Leopoldo, Rio Grande do Sul State, Brazil, evaluated the association between food insecurity and overweight in first grade students in the municipal elementary school system. A total of 2,369 students were invited to participate, of whom 847 were examined, and of these, 782 had data available on weight and height. Dietary data were obtained from a parent or guardian. Food insecurity was measured by the Brazilian Food Insecurity Scale (EBIA). Data on weight and height were provided by the Nutrition Service of the Municipal Department of Education. Prevalence rates for overweight and food insecurity were 38.1% and 45.1%, respectively. After controlling for potential confounders, children with food insecurity had 22% lower odds of overweight. Notwithstanding the inverse association between the exposure and outcome, this sample showed high rates of food insecurity and overweight, revealing a complex relationship and indicating that further research is needed to understand it. Robust public policies are critical for addressing these conditions.

Resumo O objetivo deste estudo foi descrever o comportamento sedentário (CS) nos domínios lazer, ocupação e deslocamento e verificar fatores associados ao excesso deste comportamento (ECS). Estudo transversal, com amostra representativa de 1.126 mulheres, 20-69 anos, de São Leopoldo/RS. CS, variáveis demográficas, socioeconômicas, comportamentais e relacionada à saúde foram avaliados através de questionário, aplicado em forma de entrevista. Considerou-se ECS valores acima da mediana. Utilizou-se regressão de Poisson com variância robusta. As medianas e intervalos interquartílicos (min/dia), para o CS no lazer, ocupação e deslocamento foram, respectivamente, 163,9 (86,6-2710,5), 51,4 (0-257,1) e 17,1 (5,7-37,3). A probabilidade do ECS no lazer aumentou com a escolaridade, foi maior entre as mulheres que não trabalhavam, sem crianças em casa e fumantes. Nos demais domínios, a probabilidade aumentou inversamente com a idade, foi maior entre mulheres brancas e aumentou com a classe econômica, escolaridade e renda. A probabilidade de ECS no deslocamento também aumentou com o número de carros no domicílio e foi 30% menor entre mulheres que não trabalhavam. O maior tempo de CS observado foi no domínio do lazer. As associações diferiram segundo o domínio, indicando distintas intervenções.
Abstract The aim of this study was to describe sedentary behavior (SB) across leisure, occupation, and transport domains and determine factors associated with excessive sedentary behavior (ESB). Cross-sectional survey with a representative sample of 1,126 women aged 20-69 years living in São Leopoldo/RS. SB, demographic, socioeconomic, behavioral and health factors data were collected using a questionnaire administered by interviewers. The cut-off point for ESB was defined as the median. Associations were tested using Poisson regression with robust error variance. The medians and interquartile intervals (min/day) for leisure, occupation, and transport SB were 163.9(86.6-2710.5), 51.4(0-257.1), and 17.1(5.7-37.3), respectively. The likelihood of leisure SB increased with education level, was higher among women who were not employed, lived in household without children, and smokers. In other domains, there was an inverse association between age, being white, economic class, education level, and income and ESB. Direct association between living in a household with a car and excessive transport SB and women who were not employed were 30% less likely to engage in ESB in this domain. The predominant domain in Total SB was leisure. Associations differed across domains, indicating that domain-specific interventions should be implemented in addressing excessive SB.

OBJECTIVE: To analyze if the demographic and socioeconomic variables, as well as percutaneous coronary intervention are associated with the use of medicines for secondary prevention of acute coronary syndrome. METHODS: In this cohort study, we included 138 patients with acute coronary syndrome, aged 30 years or more and of both sexes. The data were collected at the time of hospital discharge, and after six and twelve months. The outcome of the study was the simultaneous use of medicines recommended for secondary prevention of acute coronary syndrome: platelet antiaggregant, beta-blockers, statins and angiotensin-converting-enzyme inhibitor or angiotensin receptor blocker. The independent variables were: sex, age, education in years of attending, monthly income in tertiles and percutaneous coronary intervention. We described the prevalence of use of each group of medicines with their 95% confidence intervals, as well as the simultaneous use of the four medicines, in all analyzed periods. In the crude analysis, we verified the outcome with the independent variables for each period through the Chi-square test. The adjusted analysis was carried out using Poisson Regression. RESULTS: More than a third of patients (36.2%; 95%CI 28.2;44.3) had the four medicines prescribed at the same time, at the moment of discharge. We did not observe any differences in the prevalence of use in comparison with the two follow-up periods. The most prescribed class of medicines during discharge was platelet antiaggregant (91.3%). In the crude analysis, the demographic and socioeconomic variables were not associated to the outcome in any of the three periods. CONCLUSIONS: The prevalence of simultaneous use of medicines at discharge and in the follow-ups pointed to the under-utilization of this therapy in clinical practice. Intervention strategies are needed to improve the quality of care given to patients that extend beyond the hospital discharge, a critical point of transition in care.

OBJECTIVES: The purpose of this study was to evaluate the association between job characteristics and musculoskeletal pain among shift workers employed at a 24-hour poultry processing plant in Southern Brazil. METHODS: This was a cross-sectional study of 1,103 production line workers aged 18-52 years. The job characteristics of interest were shift (day/night), shift duration, and plant sector ambient temperature. Musculoskeletal pain was defined as self-reported occupational-related pain in the upper or lower extremities and trunk, occurring often or always, during the last 12 months. RESULTS: The mean (SD) participant age was 30.8 (8.5) years, and 65.7% of participants were women. The prevalence of musculoskeletal pain was greater among female participants than male participants. After adjustment for job characteristics and potential confounders, the prevalence ratios (PR) of lower extremity musculoskeletal pain among female workers employed in extreme-temperature conditions those working the night shift, and those who had been working longer on the same shift were 1.75 (95% CI 1.12, 2.71), 1.69 (95% CI 1.05, 2.70), and 1.64 (95% CI 1.03, 2.62), respectively. In male workers, only extreme-temperature conditions showed a significant association with lower extremity musculoskeletal pain (PR=2.17; 95% CI 1.12, 4.22) after adjustment analysis. CONCLUSIONS: These findings suggest a need for implementation of measures to mitigate the damage caused by nighttime work and by working under extreme temperature conditions, especially among female shift workers, such as changing positions frequently during work and implementation of rest breaks and a workplace exercise program, so as to improve worker quality of life.
