title: Desempenho Comparativo entre Países Exportadores de Pescado no Comércio Internacional: Brasil eficiente?

description: Abstract: The international trade of seafood has been expanding in the last decades, once it is pointed as of ample competition. As a way of understanding the dynamics of this trade, the objective of this research is to characterize the historical performance of seafood exporting countries in the international market, emphasizing Brazil, as well as verifying which countries foreign trade serves as a strategy of economic growth for the fishing sector and aquaculture. A performance matrix was elaborated according to the values and the trend in the historical series measured by the indices of comparative advantage revealed (IVCR) and relative position (IPR). It was verified that the efficiency of the dynamics of international trade of seafood is due to developed countries to the commercialization of fish mainly among them. In the case of Brazil, the performance was inefficient and decreasing, since fish is not an important factor in Brazilian exports as a whole, as well as the sale of the product to the foreign market is unskillful. Thus, the Brazilian seafood is not serving as a strategy of economic growth for the fishing and aquaculture sector, using international and domestic trade.

title: Inactivation of indicator microorganisms of faecal contamination by ultraviolet radiation and evaluation of photoreactivation and dark repair phenomena

description: ABSTRACT This research aimed to evaluate the performance of ultraviolet radiation (UV) for disinfecting effluents from a municipal wastewater treatment plant, in laboratory bench scale and batch operation. The interference of the operational parameters of exposure time (s) to the radiation and the level of liquid blade (cm) of the effluent in the UV reactor were analyzed. The efficiency of the disinfection process was checked using the indicators microorganisms Clostridium perfringens (C. perfringens), coliphages, Escherichia coli (E. coli) and total coliforms (TC). After disinfection, some tests were carried out to evaluate the phenomena of microbiological recovery: photoreactivation and dark repair, for E. coli and TC. The results indicate effective inactivation of indicator microorganisms by UV radiation during the time of exposure, which was statistically proved by repeated measures ANOVA. C. perfringens was the microorganism that showed the highest resistance against UV inactivation. In microbiological recovery tests, both mechanisms were considered insignificant, which was statistically proven by the Student (t test - parametric data) and the Wilcoxon (nonparametric data) tests. In all analyses, the level of significance was 5%.

title: Red wine consumption, coronary calcification, and long-term clinical evolution

description: Coronary artery calcification (CAC) is associated with atherosclerotic complications. However, elevated CAC may not always imply a worse prognosis. Herein, we report the clinical evolution of long-term red wine (RW) drinkers in relation to CAC. We followed 200 healthy male habitual RW drinkers and compared them to 154 abstainers for a period of 5.5 years. The initial evaluation included coronary computed tomography angiography (CTA), clinical, demographics, and laboratory data. CAC was quantified by the Agatston score. The follow-up process was conducted by telephone calls and/or hospital record review. The composite end-point of total death, acute myocardial infarction (AMI), or coronary revascularization (or major adverse cardiac event - MACE) was assessed. The RW drinkers ingested 28.9±15 g of alcohol/day for 23.4±12.3 years. They had higher high-density lipoprotein and low-density lipoprotein, but lower C-reactive protein than abstainers. Age, total cholesterol, triglycerides, glucose, and liver enzymes were similar. History of diabetes was lower among drinkers, but other risk factors were similar. However, drinkers had higher CAC than abstainers; the mean value was 131.5±362 in drinkers vs 40.5±320 in abstainers (P&lt;0.001). The median and interquartile range were 15 (0.0–131.5) in RW drinkers and 1 (0.0–40.5) in abstainers (P=0.003). During the follow-up, MACE was significantly lower in drinkers than in abstainers, despite their higher CAC. The difference was driven mainly by AMI (0 vs 6; P&lt;0.03). Greater CAC values in this setting did not predict worse prognosis. A possible underlying mechanism is lesion calcification, which leads to plaque stabilization and less clinical events.

title: Prevalence of arterial hypertension according to different diagnostic criteria, National Health Survey

description: ABSTRACT: Objective: To determine the population prevalence of arterial hypertension in adults according to different diagnostic criteria. Methods: This is a cross-sectional study, analyzing information from the Brazilian National Health Survey in 2013, consisted of interviews, physical and laboratory measurements (n = 60,202). The prevalence of hypertension was defined according to three diagnostic criteria: self-reported; measured by instrument (blood pressure ≥ 140/90 mmHg); measured and/or using medication. Prevalence and 95% confidence interval (95%CI) were estimated by the three diagnostic criteria of hypertension. Results: The high blood pressure measurements were: 21.4% (95%CI 20.8 - 22.0) using the criterion self-reported; 22.8% (95%CI 22.1 - 23.4) by measured hypertension; and 32.3% (95%CI 31.7 - 33.0) by measured hypertension and/or reported use of medication. Women presented higher prevalence for the self-reported criterion (24.2%; 95%CI 23.4 - 24.9) and men, for the measured criterion (25.8%; 95%CI 24.8 - 26.8). Hypertension increases with age and is more frequent in urban areas. Using these three criteria, the hypertension was higher in the Southeast and South regions, in relation to the average of the country and the other regions. Using these three criteria, hypertension increased with age, was more frequent in urban areas and in the Southeast and South regions, in relation to the average of the country and the other regions. Conclusion: These findings are important to support policies that aim to achieve the World Health Organization’s goal of reducing hypertension by 25% over the next decade.

title: Factors associated with the use of waterpipe and other tobacco products among students, Brazil, 2015

description: ABSTRACT: Objective: To identify the frequency and factors associated with the use of waterpipe and other tobacco products among Brazilian students. Methods: This is a cross-sectional study based on data from the National Adolescent Student Health Survey. The sample consisted of 9th-grade students from elementary school. We conducted a descriptive analysis of the use of tobacco products in 2012 and 2015. To explore the relationship between the use of other tobacco products and factors such as sociodemographic characteristics, family, mental health, and life habits, we calculated the adjusted odds ratio. Results: The use of other tobacco products increased from 4.8% (95%CI 4.6 - 5.0) in 2012 to 6.1% (95%CI 5.7 - 6.4) in 2015, with a higher proportion among boys. Waterpipe was the most commonly used product in 2015 (71.6%; 95%CI 68.8 - 74.2), especially among girls. Factors positively associated with the use of other tobacco products were: attending private school, living with father/mother, working, not having friends, suffering domestic violence, skipping classes, consuming cigarettes and alcohol, experimenting drug, having had sex, having smoker parents or guardians, and seeing people smoking. The protective factors were: female gender, increasing age, multiracial or indigenous people, having meals with a guardian, family supervision, and practicing physical activity. Conclusion: The use of other tobacco products was high and has been increasing in recent years, particularly waterpipe. It is important to raise awareness of the risks and monitor the use of these products, as well as improve public policies of tobacco control in the country.

title: Characteristics associated to a poor self-rated health in Brazilian adolescents, National Adolescent School-based Health Survey, 2015

description: ABSTRACT: Introduction : Health self-assessment (HSA) is a widely studied indicator among adults and the elderly, but not often explored in adolescents. This study aimed to estimate the prevalence of poor self-rated health in Brazilian schoolchildren and associated factors. Methods : Data from the 2015 National Adolescent School-based Health Survey (PeNSE) were analyzed; prevalences and their 95% confidence intervals (95%CI) were estimated for poor self-rated health and associated factors. Multiple logistic regression analysis was performed. Results : A total of 7.1% (95%CI 7.0 - 7.3) of the schoolchildren reported a poor self-assessed health status. Sociodemographic characteristics, such as female gender, 15 years of age or older, yellow, brown and indigenous race/skin color; risk behaviors such as regular alcohol consumption and drug experimentation, and issues related to physical and emotional health remained positively associated with the outcome studied. Protective factors identified were maternal schooling and demand for health services. Conclusion : The impact of risky behaviors on physical and emotional health need to be addressed among students. The school presents itself as a safe and opportune space for promoting a healthy lifestyle.

title: Nutritional status of Brazilian schoolchildren: National Adolescent School-based Health Survey 2015

description: ABSTRACT: Introduction: Obesity has increased in Brazil for all age groups. Overweight at the end of adolescence indicates a high probability of unhealthy weight in adulthood. Objective: To describe anthropometric data of the National Adolescent School-based Health Survey (PeNSE) 2015 and its distribution according to geographic and socioeconomic strata. Methods: Data from the PeNSE 2015 was used. The analysis sample consisted of adolescents aged 11 to 19 years old from public and private schools with available anthropometric data. Nutritional status was classified according to the body mass index, with reference values proposed by the International Obesity Task Force (IOTF). The prevalence estimates of underweight and overweight and their respective standard errors were presented. The association between anthropometric indicators and demographic or social characteristics of adolescents was estimated by odds ratio, and the respective 95% confidence intervals were presented. Results: The prevalence of underweight was less than 3%. Elevated prevalence of overweight was observed in adolescents from the South region, from the urban area, from the lowest fifths of income, and those who declared themselves to be black or indigenous. In general, the prevalence of overweight was higher among adolescents attending private schools. Conclusion: Overweight is more frequent among adolescents from low-income strata. Besides being an indicator of nutritional status, overweight may indicate social inequality in Brazil.

title: Trends in violent situations experienced by Brazilian adolescents: National Adolescent Student Health Survey 2009, 2012, and 2015

description: ABSTRACT: Objective: To present trends found in the last three editions of the National Adolescent Student Health Survey (Pesquisa Nacional de Saúde do Escolar - PeNSE) on violent situations experienced by Brazilian students. Methods: Time-series study with a focus on the Brazilian state capitals, using PeNSE databases of 2009, 2012, and 2015. The indicators evaluated were: missing classes due to insecurity in the home-school route or at school; involvement in a fight with firearm or melee weapon; and physical assault by an adult of the family. We estimated the prevalence of indicators according to the total number of adolescents, gender, school type, and capital. Trends in prevalence were estimated by linear regression, adjusted for age. Results: We identified a trend in increasing prevalence, with statistical significance, for all selected violence indicators in the period from 2009 to 2015, in Brazilian state capitals. Discussion: The most vulnerable groups were public schools students; male adolescents for involvement in fights with melee weapons or firearms; and female adolescents for physical assault by family members. Conclusion: PeNSE contributed to identifying the increase in the prevalence of violence experienced by adolescents, which alerts to the need of planning and implementing policies that help to prevent violence, and promote health and a culture of peace.

title: Risk and protection factors for chronic noncommunicable diseases in adolescents in Brazilian capitals

description: ABSTRACT: Objective: To analyze trend estimates on the prevalence of risk and protective behaviors for chronic noncommunicable diseases in adolescents, according to data from the National School Health Survey in 2009, 2012 and 2015. Methods: Data from the three cross-sectional studies in Brazilian capitals and the Federal District were used. In total, 173,310 adolescents enrolled in the ninth grade of elementary school were interviewed, with average age of 14 years. The prevalence of indicators of protective (consumption of beans and fruit; physical education classes at school; practice of physical activity for 60 minutes or more) and risk factors (consumption of candies and soft drinks; use of cigarettes and alcohol in the last 30 days; drug testing) were estimated through linear regression. Results: There was a significant increase (p &lt; 0.05) in the prevalence of fruit consumption and in the reduction of bean, soft drinks and candies consumption, as well as the consumption of alcoholic beverages and cigarettes. However, an increase in the prevalence of illicit drug experimentation was observed. Discussion: Despite the tendency to reduce risk factors, prevalences are high when compared with other sociocultural realities. Conclusion: The school is an important area of access to the adolescent public, and it is necessary to encourage school health promotion programs to reduce health risk behaviors, as well as to stimulate protective ones.
