OBJECTIVE To estimate the prevalence of arterial hypertension and obesity and the population attributable fraction of hypertension that is due to obesity in Brazilian adolescents.METHODS Data from participants in the Brazilian Study of Cardiovascular Risks in Adolescents (ERICA), which was the first national school-based, cross-section study performed in Brazil were evaluated. The sample was divided into 32 geographical strata and clusters from 32 schools and classes, with regional and national representation. Obesity was classified using the body mass index according to age and sex. Arterial hypertension was defined when the average systolic or diastolic blood pressure was greater than or equal to the 95th percentile of the reference curve. Prevalences and 95% confidence intervals (95%CI) of arterial hypertension and obesity, both on a national basis and in the macro-regions of Brazil, were estimated by sex and age group, as were the fractions of hypertension attributable to obesity in the population.RESULTS We evaluated 73,399 students, 55.4% female, with an average age of 14.7 years (SD = 1.6). The prevalence of hypertension was 9.6% (95%CI 9.0-10.3); with the lowest being in the North, 8.4% (95%CI 7.7-9.2) and Northeast regions, 8.4% (95%CI 7.6-9.2), and the highest being in the South, 12.5% (95%CI 11.0-14.2). The prevalence of obesity was 8.4% (95%CI 7.9-8.9), which was lower in the North region and higher in the South region. The prevalences of arterial hypertension and obesity were higher in males. Obese adolescents presented a higher prevalence of hypertension, 28.4% (95%CI 25.5-31.2), than overweight adolescents, 15.4% (95%CI 17.0-13.8), or eutrophic adolescents, 6.3% (95%CI 5.6-7.0). The fraction of hypertension attributable to obesity was 17.8%.CONCLUSIONS ERICA was the first nationally representative Brazilian study providing prevalence estimates of hypertension in adolescents. Regional and sex differences were observed. The study indicates that the control of obesity would lower the prevalence of hypertension among Brazilian adolescents by 1/5.

OBJECTIVE To determine the prevalence of metabolic syndrome and its components in Brazilian adolescents. METHODS We evaluated 37,504 adolescents who were participants in the Study of Cardiovascular Risks in Adolescents (ERICA), a cross-sectional, school-based, national study. The adolescents, aged from 12 to 17 years, lived in cities with populations greater than 100,000 inhabitants. The sample was stratified and clustered into schools and classes. The criteria set out by the International Diabetes Federation were used to define metabolic syndrome. Prevalences of metabolic syndrome were estimated according to sex, age group, school type and nutritional status. RESULTS Of the 37,504 adolescents who were evaluated: 50.2% were female; 54.3% were aged from 15 to 17 years, and 73.3% were from public schools. The prevalence of metabolic syndrome was 2.6% (95%CI 2.3-2.9), slightly higher in males and in those aged from 15 to 17 years in most macro-regions. The prevalence was the highest in residents from the South macro-region, in the younger female adolescents and in the older male adolescents. The prevalence was higher in public schools (2.8% [95%CI 2.4-3.2]), when compared with private schools (1.9% [95%CI 1.4-2.4]) and higher in obese adolescents when compared with nonobese ones. The most common combinations of components, referring to 3/4 of combinations, were: enlarged waist circumference (WC), low HDL-cholesterol (HDL-c) and high blood pressure; followed by enlarged WC, low HDL-c and high triglycerides; and enlarged WC, low HDL-c, high triglycerides and blood pressure. Low HDL was the second most frequent component, but the highest prevalence of metabolic syndrome (26.8%) was observed in the presence of high triglycerides. CONCLUSIONS ERICA is the first Brazilian nation-wide study to present the prevalence of metabolic syndrome and describe the role of its components. Despite the prevalence of Metabolic Syndrome being low, the high prevalences of some components and participation of others in the syndrome composition shows the importance of early diagnosis of this changes, even if not grouped within the metabolic syndrome.

This is a cross-sectional study conducted with 258 teachers from nine state schools in two municipalities of São Paulo state with the purpose of assessing their work ability. A questionnaire with socio-demographic and health/work conditions data and the Work Ability Index (WAI) was performed. Most teachers were females, 41.9 yr old on average (SD 9.4), and with an undergraduate degree (95.7%). The work ability was considered good for 42.6% and moderate/low for 35.3%. In linear regressions models, which used the two domain model, the significant variables for a decrease in WAI were: individual perception of a worsening in the health situation (p<0001), having children (p=0.0003 / p=0.0001), difficulty in sleeping well at night (p=0.0009 / p=0.0014), history of physical pain in the previous six months (p<0.0001 / p<0.0001), being a teacher with a contract (p=0.0007) and working as a teacher for a longer time. (p=0.0183). Public investments on the work conditions of teachers are important to recover and to maintain their work ability.

, and mental disorders (20.9%). These diseases were related to the professional risks that were described: repetitive movements, chalk dust, stressing work, long working hours, work in more of one school and low wage. It was concluded that teachers are exposed to risks at schools and that prevention and health care policies should be taken by the authorities. KEY WORDS

Objective:to identify the factors related to the nursing workers’ intention to leave the work unit, health institution and profession.Method:cross-sectional study with quantitative approach was carried out with 267 nursing workers from seven emergency units in Brazil. For data collection, we used the Questionnaire of socio-demographic, life style and work and health aspects as well as the Work Ability Index, Workplace violence questionnaire, questions about intention to leave and the Turnover Intention Scale. The predictors of intentions to leave were evaluated through Poisson regression models.Results:workplace violence increased and better satisfaction with current job decreased the probability of greater intention to leave the unit, institution and profession. Better work ability decreased the probability of greater intention to leave the unit and profession. The more qualified workers and those who had been working in the institution longer was more likely to greater intention to leave the profession.Conclusion:promoting job satisfaction, work ability and a violence-free environment is possible to decrease the workers’ intention to leave the job or profession, but nursing managers need to understand the three phenomena of intention to quit individually for retention strategies.

Epidemiological study with the purpose of identify the demographic characteristics, health aspects and life style, amongst truck drivers were applied to 105 drivers from supply center of Campinas (fruit, vegetable, product wholesale market). The outcomes showed that all drivers interviewed were men, the majority were married, had kids, low study level and more than 30 years old. 54,2% reported abuse psychoactive drugs. The majority was aware of the importance of using condoms with casual partners; 47,5% reported relationship with casual partners and 86 always used condoms. Although the small sample analyzed, the results suggests that must be implemented health promotion actions and illness prevention public politics, including the development of customized educational interventions with in this professional group.

ABSTRACT:The aim of this research was to identify the reasons for satisfaction and dissatisfaction among oncology nursing professionals working in Brazil and Portugal. A descriptive and qualitative study was conducted with nine Portuguese nurses and 17 Brazilian nursing professionals, using a questionnaire and interview, which were analyzed according to Bardin's proposition. Satisfaction, in both scenarios, was associated, above all, to the patient and the treatment process, and the bond established between the professional and the individual demanding care. Dissatisfaction resulted primarily from the extensive exposure to high workload and to the deaths of oncology patients. The importance of considering the subjectivity that permeates the work scenario is highlighted, which can have vast and, sometimes, costly implications. DESCRIPTORS:Work. Job satisfaction.

SATISFAÇÃO E INSATISFAÇÃO NO TRABALHO DE PROFISSIONAIS DE ENFERMAGEM DA ONCOLOGIA DO BRASIL E PORTUGALRESUMO: Objetivou-se nesta pesquisa identificar os motivos de satisfação e insatisfação entre profissionais de enfermagem que atuavam na atenção oncológica, no Brasil e em Portugal. Estudo com abordagem qualitativa, descritivo, realizado com nove enfermeiros portugueses e dezessete profissionais de enfermagem brasileiros, utilizando-se de questionário e entrevista. Os dados foram analisados na proposta de Bardin. A satisfação, em ambos os cenários, esteve associada, sobretudo, ao paciente e processo de tratamento, e ao vínculo estabelecido entre o profissional e o indivíduo que demanda por seus cuidados. A insatisfação decorreu, prioritariamente, da exposição à exaustiva carga de trabalho e óbito do paciente oncológico. Foi destacada a relevância de se atentar à subjetividade que permeia o cenário laboral, cujas implicações podem ser vastas e, por vezes, onerosas. DESCRITORES:Trabalho. Satisfação no trabalho.

SATISFACCIÓN E INSATISFACCIÓN EN EL TRABAJO DE PROFESIONALES DEL ENFERMERÍA DE ONCOLOGÍA DEL BRASIL Y PORTUGALRESUMEN: El objetivo de esta investigación fue identificar las razones de la satisfacción y insatisfacción entre los profesionales de enfermería que trabajan en la atención oncológica en Brasil y Portugal. Estudio descriptivo y cualitativo realizado con nueve enfermeras portuguesas y diecisiete profesionales de la enfermería brasileña, utilizando cuestionarios y entrevistas, más tarde una transcripción y analizado con la proposición de Bardin. La satisfacción, en ambos escenarios, se asocia, sobre todo, para el paciente y el proceso de tratamiento, y el vínculo que se establece entre el profesional y la persona exigente para su cuidado. La insatisfacción se debió principalmente a la amplia exposición de la carga de trabajo y la muerte de los pacientes oncológicos. Destacó la importancia de considerar la subjetividad que impregna el escenario de trabajo, que puede tener enorme y, a veces, consecuencias costosas. DESCRIPTORES:Trabajo. Satisfacción en el trabajo.
