Dietary intake in children and adolescents with food addiction: A systematic review.

Food addiction (FA) is characterized by behavioral changes related to the consumption of palatable foods, marked by dependence, impulsivity, and compulsion. Children and adolescents are more vulnerable to FA owing to their significant consumption of ultra-processed foods. This review aims to investigate the differences in dietary intake in pediatric populations with and without FA. We conducted a systematic literature review. PubMed, ScienceDirect, and PsycINFO databases were searched up to July 2023. Potentially eligible studies were independently checked by two researchers. The methodological quality of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for analytical cross-sectional studies. Of the 4868 articles identified, six studies were included. All the included studies had high methodological quality. High consumption of calories and fat was observed in children and adolescents with FA. A diet quality analysis showed that the consumption of ultra-processed foods, such as sugary drinks, sweets, and chips, was related to FA. Given these findings, we concluded that FA in childhood may be associated with higher energy consumption and, consequently, higher intake of macronutrients. Few studies have examined the relationship between FA and food intake in childhood, and more studies are required.

Olive leaf extract effect on cardiometabolic risk factors: a systematic review and meta-analysis of randomized clinical trials.

CONTEXT: Olive leaf extract (OLE) is rich in phenolic compounds, which are known for their health benefits. Cardiovascular diseases, primarily coronary heart disease and stroke, are leading causes of mortality globally. OBJECTIVE: This systematic review aimed to assess the impact of OLE on cardiometabolic risk factors in adults. The selection of studies was based on intervention and outcomes, using relevant search descriptors. DATA SOURCES: The databases PubMed, EMBASE, and Web of Science were systematically searched for pertinent studies published up to August 2021. DATA EXTRACTION: Only randomized clinical trials, either cross-over or parallel, involving adult individuals aged ≥18 years, were considered. Additionally, trials that had a comparative or placebo group and used pure OLEs for oral treatment were included. DATA ANALYSIS: Twelve randomized clinical trials (RCTs) met the inclusion criteria. These trials had follow-up periods ranging from 2 days to 12 weeks and involved 703 patients aged 18 years-79 years. The outcomes demonstrated a positive correlation between the intervention group and glucose metabolism (4 RCTs), blood pressure (2 RCTs), lipid profile (2 RCTs), and inflammatory markers (2 RCTs). The RoB2 tool and the GRADE system were used to evaluate the risk of bias and the quality of evidence in the studies. CONCLUSIONS: In the meta-analysis, fasting glycemia, as evaluated in studies using a low dose of OLE, showed a significant result favoring the control group. To obtain more consistent results, further clinical studies in humans, using similar methodologies, are required. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42020200877.

Prevalence of Abdominal Obesity and Associated Factors in Urban Brazilian Women: A Comparison Between Two Population-Based Cross-Sectional Studies in 2003 and 2015.

Background: Abdominal fat accumulation is a known risk factor for cardiometabolic diseases and mortality, particularly in women. This study aimed to compare the prevalence of abdominal obesity and its associated factors in 2003 and 2015. Methods: Two cross-sectional, population-based surveys were conducted, including representative and independent samples of adult women 20-60 years of age residing in the urban area of São Leopoldo/RS municipality in 2003 (n = 981) and 2015 (n = 984). Abdominal obesity was assessed using waist circumference, with a measurement of ≥88 cm indicating its presence. Factors, such as demographics, socioeconomic status, reproductive health, family history, morbidity, and behavioral characteristics, were studied. Poisson regression was used to assess the associations. Results: The mean age of individuals in the samples was 38.5 years (±11.1 years) and 40.3 years (±11.4 years) in 2003 and 2015, respectively. The prevalence of abdominal obesity doubled from 23.3% (95% confidence interval [CI]: 20.7-26.0) in 2003 to 46.9% (95% CI: 43.7-50.0) in 2015. After adjustment, the prevalence of abdominal obesity remained higher in both 2003 and 2015 with increasing age, low family income, higher number of pregnancies, earlier age at menarche, and presence of a family history of obesity in the father and mother and in women with a history of hypertension. Conclusions: This study demonstrates an increase in the prevalence of abdominal obesity in women between 2003 and 2015 and highlights the sociodemographic, reproductive, family history, and comorbidity aspects associated with its occurrence.

Prevalence of common mental disorders in southern Brazilian women: a comparison of two population-based studies (2003 vs. 2015).

PURPOSE: To investigate the prevalence and associated factors of common mental disorders (CMD) in women, and comparing them in two periods, 2003 and 2015. METHODS: A comparative study was conducted between two surveys with representative samples of women aged 20-60 years residing in southern Brazil. The final sample included 988 and 987 women from the 2003 and 2015 surveys, respectively. The presence of CMD was assessed using the Self-Reporting Questionnaire (SRQ-20 ≥ 8) in both surveys. Poisson regression analysis was used to evaluate the associations between the outcome (CMD) and variables of interest. RESULTS: The mean age of the participants was 38.5 ± 11.1 years (2003) and 40.3 ± 11.4 years (2015). In 2003, the prevalence of CMD was 33.4% (95%CI: 30.5-36.3) and in 2015, it was 33.7% (95%CI: 30.8-36.7). Over 12 years, no significant differences were observed in the prevalence of CMD, except for a reduction in the prevalence in women of color and physically active. After adjusting, the prevalence ratios of CMD in 2003 and 2015 remained associated with low family income, a higher number of pregnancies, and tobacco use. CONCLUSIONS: This study showed a trend toward stability in the high prevalence of CMD among women.

Association between obesity and common mental disorders in women: a population-based study in Southern Brazil.

PURPOSE: The study aimed to investigate the relationship between obesity and common mental disorders (CMD) among women. METHODS: This is a cross-sectional population-based study with a representative sample of 981 adult women (20-60 years of age) living in the urban area of the municipality of São Leopoldo, RS, Brazil, in 2015. The presence of CMD was assessed using the Self-Reporting Questionnaire (SRQ-20 ≥ 8). Obesity was defined by body mass index (BMI ≥ 30.0 kg/m2). Prevalence ratios (PRs) for the association between obesity and CMD were measured by Poisson regression with robust variance, including their respective 95% confidence intervals (CIs). RESULTS: The mean age of the sample was 40.3 years (standard deviation = 11.4 years). The prevalence of CMD was 33.7% (95% CI 30.8-36.7), while obesity was 31.2% (95% CI 28.3-34.1). The occurrence of CMD was higher in women with low levels of education and belonging to lower economic class, as well as smokers and those who were insufficiently active. Obesity was more prevalent in older women (50-60 years old) with less schooling, who did not consume alcohol, and those who were insufficiently active. After adjusting for potential confounding factors, women with obesity were 22% more likely to have CMD when compared to those without obesity (PR = 1.22; 95% CI 1.02-1.45; p = 0.030). CONCLUSIONS: This study demonstrated a significant association between obesity and the presence of CMD among women. Additionally, the prevalence of obesity and CMD were high in this population group.

Association between social capital and food patterns in women from Southern Brazil. / Associação entre capital social e padrões alimentares em mulheres do Sul do Brasil.

The present study aimed to verify the association between psychosocial aspects (social capital) and food patterns in adult women. A cross-sectional, population-based study was conducted with a representative sample of 1,128 women, aged 20 to 69 years, living in the urban area of the municipality of São Leopoldo, Rio Grande do Sul, Brazil, in 2015. The food patterns were identified based on the frequency of food intake and classified as: healthy (fruits, vegetables, and whole foods), at-risk (ultraprocessed foods), and Brazilian (rice and beans), while social capital was evaluated using a collective efficacy scale. It was observed that 18.9% of the sample was classified with high collective efficacy. After adjusting for potential confounding factors, a 44% higher probability was observed for adherence to the healthy pattern (PR [prevalence ratio] = 1.44; 95%CI [95% confidence interval]: 1.01-2.03; p = 0.040) and 71% higher for the Brazilian pattern (PR = 1.71; 95%CI: 1.18-2.47; p= 0.004) among women with a higher level of collective efficacy, when compared to those with a low level of collective efficacy. Thus, this study verified a significant relationship between psychosocial aspects and food intake in women.

O presente estudo objetivou verificar a associação entre aspectos psicossociais (capital social) e padrões alimentares em mulheres adultas. Realizou-se um estudo transversal, de base populacional, com uma amostra representativa de 1.128 mulheres, de 20 a 69 anos de idade, residentes na área urbana do município de São Leopoldo, Rio Grande do Sul, em 2015. Os padrões alimentares foram identificados com base na frequência de consumo alimentar e classificados em: saudável (frutas, vegetais e alimentos integrais), de risco (alimentos ultraprocessados) e brasileiro (arroz e feijão), enquanto o capital social foi avaliado por meio de uma escala de eficácia coletiva. Observou-se que 18,9% da amostra foi classificada com alta eficácia coletiva. Após ajuste para potenciais fatores de confusão, observou-se uma probabilidade 44% maior para adesão ao padrão saudável (RP [razão de prevalência] = 1,44; IC95% [intervalo de confiança de 95%]: 1,01-2,03; p = 0,040) e 71% maior para o padrão brasileiro (RP = 1,71; IC95%: 1,18-2,47; p = 0,004) entre as mulheres com um maior nível de eficácia coletiva, quando comparadas às com baixo nível de eficácia coletiva. Assim, este estudo verificou uma relação significativa entre aspectos psicossociais e consumo alimentar em mulheres.

Common mental disorders in Brazilian female shift workers: prevalence and associated factors.

This study aimed to identify the prevalence of common mental disorders (CMD) and associated factors in female shift workers. A cross-sectional study was conducted with a sample of 450 female workers, aged 18 years or older (± 36.1 years), from an industry located in Southern Brazil. CMD was assessed using the self-reporting questionnaire (SRQ-20 ≥ 8 points), and sociodemographic, occupational, behavioral, morbidity, and self-rated health characteristics were assessed using a questionnaire survey. The prevalence of CMD was 47.3% (95% CI: 42.6-52.1). After adjusting, female workers with black/brown race/skin color had a 22% higher probability of CMD than white workers (prevalence ratio (PR) = 1.22; 95% CI: 1.01-1.49), and workers with sleep disorders or poor sleep quality were 147% more likely to have CMD compared with those with good sleep quality (PR = 2.47; 95% CI: 1.70-3.58), and workers with fair/poor self-rated health were twice as likely to have CMD (PR = 2.00; 95% CI: 1.43-2.80) compared to those with excellent/very good self-rated health. A high prevalence of CMD was observed in female shift workers, especially in workers with a black/brown race/skin color and with poor sleep quality and self-rated health.

Overweight and obesity among Brazilian healthcare university students: prevalence and associated factors

ABSTRACT Objective: Obesity is an important factor for cardiovascular and metabolic events. Thus, this study aimed to assess the prevalence of overweight/obesity and the associated factors among healthcare university students. Materials and methods: A cross-sectional university-based study of 2,245 healthcare university students in the Midwest region of Brazil was conducted in 2018. Overweight and obesity were defined as body mass index (BMI) ≥ 25 kg/m2 and BMI ≥ 30 kg/m2, respectively. Demographic, socioeconomic, behavioral, family and comorbidities characteristics were investigated. Poisson regression was used for the multivariable analysis. All analysis was stratified by sex. Results: The mean age of the sample was 22.7 years (standard deviation = 4.1) and 69.5% of the students was female. The prevalence of overweight and obesity were 13.9% (95% confidence interval [CI]: 12.2-15.6) and 4% (95% CI: 3.0-4.9) for women and 34.5% (95% CI: 30.9-38.1) and 11.3% (95% CI: 8.9-13.6) for men, respectively. After multivariate adjustment, the prevalence of overweight/obesity was at least 70% higher in female students aged 24 years or older (prevalence ratio [PR] = 1.73; 95% CI: 1.24-2.41) and those who smoke (PR = 1.95; 95% CI: 1.66-3.02). Additionally, female students with a family history of obesity (PR = 2.01; 95% CI: 1.46-2.77) or with two or three comorbidities (PR = 2.09; 95% CI: 1.43-3.04) exhibited a significantly higher probability for overweight/obesity. Similar findings were observed in male students, but with smaller effect sizes. Conclusion: This study revealed a high prevalence of overweight/obesity among healthcare university students, especially in men. It was related to the socio-demographic and family characteristics rather than behavioral factors.

Antioxidant Mechanisms Underlying the Gastroprotective Effect of Menthofuran on Experimentally Induced Gastric Lesions in Rodents.

Menthofuran is a monoterpene present in various essential oils derived from species from Mentha genus, and in Brazil, those species are widely used in treating gastrointestinal and respiratory disorders. Considering the wide pharmacological potential of monoterpenes, including their antioxidant activity, this study aimed to evaluate menthofuran-gastroprotective activity, as well as the involvement of antioxidant mechanisms in this effect. The acute toxicity was evaluated according to the fixed dose method. The antiulcerogenic activity was investigated by using experimental models of gastric ulcers induced by ethanol, indomethacin, and ischemia/reperfusion in rats. The antisecretory gastric activity, the catalase activity, and the gastric wall mucus were determined in pylorus ligated rats. Gastric wall nonprotein sulfhydryl (NPSH) group content, myeloperoxidase (MPO) activity, and malondialdehyde (MDA) content were evaluated in ethanol-induced the gastric ulcer model. Menthofuran (2 g/kg) presented low acute toxicity and showed gastroprotective activity against ethanol-, indomethacin-, and ischemia/reperfusion-induced ulcers. Moreover, menthofuran presented antisecretory activity, reduced the total acidity, and increased pH of gastric secretion. On the other hand, a decrease in mucus content of gastric wall without alteration of gastric juice volume and catalase activity was observed. Interestingly, menthofuran increased NPSH levels and reduced MDA levels and MPO activity. Gastroprotective effects of menthofuran appear to be mediated, at least in part, by the NOS pathway, endogenous prostaglandins, reduced gastric juice acidity, increased concentration of the NPSH groups, and reduced lipidic peroxidation. These findings support the menthofuran as an effective gastroprotective agent, as well as the marked participation of antioxidant mechanisms in this response.

Resumo Introdução As escolhas alimentares podem ser influenciadas por apoio social e capital social. Objetivo Investigar as relações do apoio social e capital social com o consumo alimentar. Método Trata-se de um estudo transversal, de base populacional, com uma amostra aleatória de 1.098 adultos (≥ 18 anos de idade) de uma cidade no Sul do Brasil. O apoio social foi mensurado por meio da escala Medical Outcomes Study (MOS), e o capital social contemplou a avaliação dos indicadores de coesão social, apoio dos vizinhos, controle social informal, eficácia política e ação social. Para o consumo alimentar, utilizou-se de uma escala com base nas orientações do guia alimentar para a população brasileira. Resultados A média de idade da amostra foi de 44 anos (DP[Desvio-padrão] = 15,8), e identificou-se um consumo alimentar adequado em 38,6% (IC95%: 35,7 a 41,5). Após ajuste, observou-se uma probabilidade 40% maior para adoção de consumo alimentar adequado (saudável) entre os indivíduos com maior nível de apoio social (OR = 1,47; IC95%: 1,07 a 2,03), coesão social (OR = 1,40; IC95%: 1,02 a 1,92) e apoio dos vizinhos (OR = 1,45; IC95%: 1,04 a 2,02). Conclusão Os aspectos psicossociais, tanto individual quanto contextual, podem desempenhar um papel importante no consumo alimentar saudável em adultos.

Conclusion Both individual and contextual psychosocial aspects can play an important role in healthy food consumption in adults.

Dor lombar em estudantes universitários: qual o impacto da pandemia de COVID-19? / Dolor lumbar en universitarios: ¿cuál es el impacto de la pandemia del COVID-19? / Low back pain in university students: what is the impact of COVID-19 pandemic?

RESUMO O isolamento social decorrente da pandemia de COVID-19 alterou os hábitos da população e levantou questões relacionadas à saúde, por exemplo, a dor lombar. Este estudo teve por objetivo avaliar a prevalência e o risco de cronicidade de dor lombar em universitários durante o isolamento social. Para isso, foi utilizado um questionário on-line. O instrumento STarT Back Screening Tool (SBST) foi utilizado para verificar a dor lombar. Os fatores investigados foram: dados sociodemográficos, informações sobre dor e informações sobre comportamento sedentário e atividade física. Utilizou-se o teste de qui-quadrado para heterogeneidade de proporções. A análise ajustada foi realizada mediante regressão de Poisson com variância robusta. A amostra foi composta por 208 estudantes. Verificou-se que universitários com companheiro apresentaram duas vezes mais chance de dor (RP=2,07; IC95%) em comparação aos solteiros. A prevalência de dor lombar foi de 48,1%; sendo 87% maior nas mulheres (RP=1,87; IC95%: 1,09-3,21; p=0,027) quando comparadas aos homens. Universitários com comportamento sedentário apresentaram uma probabilidade 35% maior de ter dor lombar (RP=1,36; IC95%: 1,02-1,81; p=0,038); e obesos 42% (RP=1,42; IC95%: 1,04-1,94; p=0,032). O risco de cronicidade foi baixo em 82% da amostra. A dor lombar esteve presente na vida de muitas pessoas durante o isolamento social imposto pela COVID-19. Trata-se de um problema comum, limitante, e que deve ser considerado e tratado como prioridade em saúde e pesquisa.

ABSTRACT The social isolation resulting from the COVID-19 pandemic has changed the population's habits and raised health-related issues, such as low back pain. This study aimed to evaluate the prevalence and risk of chronic low back pain in university students during the social isolation of COVID-19. We used an online questionnaire, the STarT Back Screening Tool (SBST), to check for low back pain. The factors investigated: sociodemographic data, pain, sedentary behavior, and physical activity. For proportion heterogeneity, we used the chi-square test. The adjusted analysis used Poisson regression with robust variance. A total of 208 students participated in the sample. University students with a partner were twice as likely to have pain (PR=2.07; 95%CI). The prevalence of low back pain was 48.1%; 87% (PR=1.87; 95%CI: 1.09-3.21; p=0.027) higher in women. University students with obesity were 42% more likely to have low back pain (PR=1.42; 95%CI: 1.04-1.94; p=0.032); and with sedentary behavior were 35% more likely to have low back pain (PR=1.36; 95%CI: 1.02-1.81; p=0.038). In total, 82% of the sample presented low risk of chronicity. Many people presented low back pain during the social isolation imposed by COVID-19. This is a common, limiting problem that must be considered and treated as a health and research priority.

Association between the community food environment and dietary patterns in residents of areas of different socio-economic levels of a southern capital city in Brazil.

This study aimed to verify the association between the community food environment and dietary patterns in a population of different socio-economic levels. This cross-sectional study was conducted with a sample of 400 adults and elderly aged between 20 and 70 years residing in the central area of Porto Alegre, Rio Grande do Sul. Four dietary patterns were explored: healthy, traditional Brazilian, refined carbohydrates and sugars, and fast food. The community food environment included the identification of all food stores by areas where individuals lived and auditing based on the Nutrition Environment Measures Survey in Stores (NEMS-S) score. Poisson regression was used to estimate the prevalence ratios (PR) and their respective 95 % CI. After the adjustment for individual sociodemographic characteristics, residents of the area with the best community food environment (highest NEMS-S score) had 12 % and 18 % lower probabilities of high consumption (upper tertile) of the traditional (PR = 0·88; 95 % CI (0·78, 0·98)) and refined carbohydrate and sugar (PR = 0·82; 95 % CI (0·73, 0·92)) dietary patterns, respectively, compared with those living in the area with the worst community food environment (lowest NEMS-S score). Healthy and fast-food dietary patterns showed no association with the community food environment. In conclusion, the community food environment is a factor associated with the consumption of certain dietary patterns, independent of individual sociodemographic characteristics. Thus, aspects of the community food environment become important in food and nutrition actions and policies aimed at health promotion.

Relationship between temperature and relative humidity on initial spread of COVID-19 cases and related deaths in Brazil.

INTRODUCTION: Climate conditions may influence the transmission of COVID-19. Thus, the aim of this study was to evaluate the impact of temperature and relative humidity on COVID-19 cases and related deaths during the initial phase of the epidemic in Brazil. METHODOLOGY: An ecological study based on secondary data was conducted. Daily data on new COVID-19 cases, deaths, and climate indicators were collected from February 20 to April 18, 2020 (n = 59 days) for all state capital cities in Brazil and the Federal District (Brasília). The climate indicators included mean temperature, temperature amplitude, mean relative humidity, relative humidity amplitude, and percentage of days with mean relative humidity ≤ 65 %. Correlation and multiple linear regression analyses were performed for all cities and stratified by quintiles of the COVID-19 incidence rate. RESULTS: The mean daily temperature was positively correlated with the number of days until the first COVID-19 case was reported. A lower mean relative humidity was correlated with a lower number of cases and deaths in Brazil, especially when the relative humidity was ≤ 65 %. Higher temperatures and humidity amplitudes were correlated with lower COVID-19 mortality. Additionally, after controlling for humidity, cumulative cases of COVID-19 were inversely associated with temperature in cities with mean temperatures less than 25.8 °C. CONCLUSIONS: Variations in temperature and humidity across the Brazilian territory may have influenced the spread of the novel coronavirus during the initial phase of the epidemic.

Does sleep quality modify the relationship between common mental disorders and chronic low back pain in adult women?

OBJECTIVE: This study explored the association between common mental disorders (CMD) and chronic low back pain (CLBP) in women, while considering poor sleep quality as a potential effect modifier of this relationship. METHODS: A cross-sectional population-based study was conducted with a representative sample of 1068 women (age 20-69 years) living in the urban area of São Leopoldo, RS, Brazil. CLBP was defined as pain lasting for ≥3 months; CMD was assessed using the Self-Reporting Questionnaire (SRQ-20; score ≥8); poor sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI; score ≥5). Poisson regression with robust variance was used to estimate the prevalence ratios (PR) with 95% confidence intervals (CI). RESULTS: The prevalence of CLBP, CMD, and poor sleep quality was 46.8% (95% CI: 43.8-49.8), 33.5% (95% CI: 30.3-36.3), and 42.3% (95% CI: 39.3-45.2), respectively. Poor sleep quality was a significant modifier of the association between CMD and CLBP. Among women with poor sleep quality, women with CMD had a 48% higher probability of having CLBP compared to women without CMD and after adjustment for confounders (PR = 1.48; 95% CI: 1.23-1.77; p < 0.001). The relationship between CMD and CLBP was not statistically significant in women with good sleep quality. CONCLUSIONS: This study revealed a significant relationship between CMD and CLBP, wherein poor sleep quality acted as an effect modifier. Women with CMD and poor sleep quality were more vulnerable to CLBP.

Obesity Among Industrial Workers in Brazil: A Cross-sectional Study on Prevalence and Associated Factors.

OBJECTIVE: Estimate the prevalence of obesity and its associated factors among industrial workers. METHODS: This is a cross-sectional study of secondary data from workers aged 18 to 59 years in the State of Rio Grande do Sul, Brazil. RESULTS: A total of 20,820 workers (12,372 men and 8448 women) were investigated. The overall prevalence of obesity was 14.6% (95% CI [confidence interval]: 14.2 to 15.1), 16.4% (95% CI: 15.6 to 17.2) among women and 13.5% (95% ci: 12.9 to 14.1) among men. After adjusting, obesity was significantly associated with increasing age, living with a partner, lower education, and ex-smoking status in both sexes. However, it was associated with lower income in women, and higher income and physical inactivity in men. CONCLUSIONS: Obesity was prevalent among Brazilian industrial workers and sociodemographic characteristics are important factors related to obesity.

Prevalence and factors associated with excessive and severe daytime sleepiness among healthcare university students in the Brazilian Midwest.

The present study aimed to determine the prevalence of, and factors associated with excessive and severe daytime sleepiness in healthcare university students. A cross-sectional university-based study was conducted with 1,779 students from a university located in the Brazilian Midwest State of Goiás, Brazil, in 2018. Daytime sleepiness was assessed using the Epworth Sleepiness Scale (ESS) and classified as excessive daytime sleepiness (EDS; cut-off ESS score ≥10) and severe EDS (S-EDS; cut-off ESS score ≥16). Associated factors included sociodemographic, behavioural, academic, nutritional status, and sleep-related and perceived health characteristics. Poisson regression was used for the data analysis. The mean (SD) age of the sample was 22.5 (3.84) years. The prevalence of EDS was 54.4% (95% confidence interval [CI] 51.9-56.1) and S-EDS was 10.0% (95% CI 9.2-11.7). After adjustment, a higher probability of occurrence of EDS was found among women (prevalence ratio [PR] 1.37, 95% CI 1.24-1.53), younger students (PR 1.23, 95% CI 1.07-1.42), those who were studying medicine (PR 1.14, 95% CI 1.02-1.28), with poor sleep quality (PR 1.29, 95% CI 1.17-1.43), and among those who reported constant loss of sleep due to internet use (PR 1.14, 95% CI 1.02-1.27). After adjustment, the highest probability of occurrence of S-EDS was found among women (PR 1.72, 95% CI 1.22-2.43), among those with poor sleep quality (PR 2.17, 95% CI 1.54-3.08), and medical students (PR 1.39, 95% CI 1.01-1.90). In conclusion, there was a high prevalence of daytime sleepiness among healthcare university students, especially among medical students and women.

Fatores Associados à Ocorrência de Hipertensão Arterial em Trabalhadores da Indústria do Estado do Rio Grande do Sul, Brasil / Factors Associated with the Occurrence of Arterial Hypertension in Industry Workers of State of Rio Grande do Sul, Brazil

Resumo Fundamento A hipertensão é um importante e persistente problema de saúde pública, sendo uma das principais causas de doenças cardiovasculares e mortalidade geral. Objetivos Este estudo buscou verificar a prevalência e os fatores associados à hipertensão arterial sistêmica em trabalhadores da indústria do estado do Rio Grande do Sul, Brasil. Métodos Trata-se de um estudo transversal com dados secundários de 20.792 industriários de 18 a 59 anos de idade. A presença de hipertensão arterial foi determinada a partir da pressão arterial sistólica ≥140mmHg e/ou pressão arterial diastólica ≥90mmHg, ou estar fazendo uso de medicação anti-hipertensiva. Os fatores investigados incluíram características demográficas, socioeconômicas, comportamentais, de estado nutricional e de história familiar. Regressão de Poisson foi utilizada na análise multivariável, adotando-se um p<0,05 como nível de significância. Todas as análises foram estratificadas por sexo. Resultados A amostra incluiu 12.349 homens e 8.443 mulheres com média de idade geral de 32,8 anos (Desvio-padrão=9,8 anos). A prevalência de hipertensão foi de 10,3% (IC95%:9,8-10,7), sendo esta significativamente maior entre os homens do que entre as mulheres (10,9% vs 9,4%;p=0,001). A hipertensão mostrou-se associada à elevação da faixa etária, baixa escolaridade, viver com companheiro, ter sobrepeso ou obesidade, e ter pelo menos um parente com história de hipertensão para ambos os sexos. As mulheres com melhores condições socioeconômicas apresentaram menores prevalências de hipertensão. Conclusões Os principais fatores associados à hipertensão arterial compreenderam características sociodemográficas, nutricionais e de história familiar.

Abstract Background Hypertension is a serious and persistent public health problem and is one of the main causes of cardiovascular diseases and general mortality. Objectives This study aimed to verify the prevalence and factors associated with systemic arterial hypertension in workers from the state of Rio Grande do Sul, Brazil. Methods This is a cross-sectional study using the secondary data from 20,792 industry workers from 18 to 59 years of age. The presence of arterial hypertension was determined from systolic blood pressure ≥ 140mmHg and/or diastolic blood pressure ≥ 90mmHg or taking antihypertensive medication. Factors investigated included demographic, socioeconomic, behavioral, nutritional status, and family history characteristics. Poisson regression was used in multivariate analysis, adopting a significance level of p<0.05. All analyses were stratified by sex. Results The sample included 12,349 men and 8,443 women with a mean age of 32.8 years (Standard Deviation = 9.8). The prevalence of arterial hypertension was 10.3% (95% CI: 9.8-10.7), which was significantly higher in men than in women (10.9% vs 9.4%; p = 0.001). Arterial hypertension was associated with increased age, a low level of education, living with a partner, being overweight or obese, and having at least one relative with a history of hypertension for both sexes. Women with better socioeconomic conditions presented a lower prevalence of hypertension. Conclusions The main factors associated with hypertension included sociodemographic, nutritional, and family history characteristics. In addition, socioeconomic conditions showed an association with the occurrence of hypertension, especially among women.
