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.

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: Analysis of sexual and reproductive health indicators of Brazilian adolescents, 2009, 2012 and 2015

description: ABSTRACT: Objective: To analyze sexual and reproductive health indicators of adolescents based on data from the National School-based Health Survey (PeNSE) in 2015, comparing them to the data from 2009 and 2012. Methods: Cross-sectional study that has analyzed data from 9th grade students from PeNSE 2015, 2012 and 2009. We estimated prevalence and 95% confidence intervals for the following indicators: sexual initiation, condom use in the last sexual intercourse, counseling for pregnancy, sexually transmitted infections and free condoms in the three rounds of the survey. Prevalence of all indicators accessed in 2015 was estimated according to sex, type of school and region. Pearson’s χ2 test was used. Results: The prevalence of sexual initiation reported by adolescents has decreased from 30.5%, in 2009, to 27.5%, in 2015, as well as the use of condom in the last intercourse, from 75.9 to 66.2%, respectively. In respect to counseling, there was a reduction regarding pregnancy prevention in public schools, from 81.1 to 79.3% and in relation to free condom in private schools, from 65.4 to 57.3%. About 30% reported using both condom and another contraceptive method, and 19.5% did not use any method. Boys presented greater prevalence of sexual initiation, higher number of partners and reduced prevalence of condom use. Adolescents living in North, Northeast and Central-West regions presented worse indicators. Conclusion: There was a reduction in sexual initiation and condom use among Brazilian adolescents, boys were more vulnerable to sexually transmitted infections, and girls from public schools were more vulnerable to pregnancy.

title: Profile and trend of risk factors for traffic accidents in schoolchildren in Brazilian capitals: PeNSE 2009, 2012 and 2015

description: ABSTRACT: Introduction: Land transport accidents (LTA) are the second cause of death in schoolchildren aged 13 to 17 years. The study aims to describe the risk factors for LTA in schoolchildren from the National School Health Survey (PeNSE) of 2015 and to evaluate the trend of selected indicators in the last three editions of PeNSE. Methodology: A descriptive study on risk factors for LTA in 2015, with PeNSE data and time series trends analysis, with age-adjusted regression tests of the 2009, 2012 and 2015 editions, in Brazilian capitals. Results: In 2015, 26.3% of ninth grade schoolchildren, mostly between 13 and 15 years of age, reported having been in a motor vehicle driven by someone who consumed alcohol and 32.4% had driven a motor vehicle; 30.7% of adolescents did not use seat belts in the back seat; and 16.8% of schoolchildren who ride motorcycles did not wear helmets. There was also a worsening of the indicators between 2009 and 2015, regarding driving a motor vehicle (1.0 percentage points) and having been driven by vehicle for consumption of alcoholic beverages (1.1 percentage points). Discussion: The LTA occurrence results from the interaction between roads, vehicles and users, and has a strong correlation with behavior. Conclusions: The results show the need to invest in educational measures, associated with supervision, the improvement of road infrastructure, research and improvement of legislation. The monitoring of risk factors in schoolchildren substantially contributes to support intersectoral public policies interventions to reduce morbidity and mortality in traffic.

title: Nutritional status, body image, and their association with extreme weight control behaviors among Brazilian adolescents, National Adolescent Student Health Survey 2015

description: ABSTRACT: Introduction: This study aimed to analyze the association between nutritional status, body image perception, and extreme weight control behaviors among adolescents. Methods: This is an analytical cross-sectional study conducted in Brazil based on the National Adolescent Student Health Survey (Pesquisa Nacional de Saúde do Escolar - PeNSE) of 2015, with adolescents aged 13 to 17 years. Nutritional status and body image perception were the independent variables. The two dependent variables were vomiting or laxative use and use of medicines and other formulas for weight control in the 30 days prior to data collection. We used Poisson regression models for association, with demographic variables for control. Results: 7.4% of adolescents (95%CI 6.7 - 8.2) reported vomiting or using laxatives, with no difference between genders. The prevalence of use of medicines and formulas was higher among boys (7.8%; 95%CI 6.6 - 8.9). The association between nutritional status and extreme behaviors was not significant. However, the prevalence of vomiting or laxative use for adolescents who considered themselves very fat was 2.3 (95%CI 1.1 - 4.7) times higher for boys and 5.3 (95%CI 3.3 - 8.6) times higher for girls, while the use of medicines and formulas was 4.0 (95%CI 2.3 - 7.1) times higher for girls who considered themselves very fat. Conclusion: Body image perception seems to have a greater influence on extreme behaviors than nutritional status. Strategies involving health services and schools have great potential to impact the self-esteem and health of students positively.

title: Economic integration and development: investment financing strategies regarding south American infrastructure

description: Abstract The aim of this paper is to analyze the investment financing schemes for South American economic integration in infrastructure. The initiatives considered include increasing the stake of these countries in the Development Bank of Latin America (CAF) and its regional role; Fonplata and IDB. The analysis of these schemes was based on resources that included the IIRSA - Cosiplan portfolio in relation to the participation of National Treasures by comparing the number and volume of resources for the EID - the scope of the projects they finance, the evolution of its loan portfolio as a whole or for regional physical integration and number of projects completed compared to those already running and predicted for portfolio. An important result that must be highlighted is the existence of isolated schemes and, in part, inadequate regional physical integration funding.

title: Parental supervision and alcohol use among Brazilian adolescents: analysis of data from National School-based Health Survey 2015

description: ABSTRACT: Objective: To evaluate the relation between parental supervision and sociodemographic factors and alcohol use by Brazilian adolescents. Methods: This is a cross-sectional study with data from National School-based Health Survey (PeNSE) 2015, which included 16,608 adolescents aged 13 to 17 years, students from Brazilian public and private schools. Variables related to alcohol use, sociodemographic factors and parental supervision were evaluated. In order to analyze the relation between sociodemographic variables, parental supervision and use of alcohol among adolescents, prevalence ratios stratified by sex were used. Results: It was observed that 61.4% of the adolescents had tried alcohol, 27.2% had a drunken episode in their lifetime, 9.3% have had problems with alcohol and 29.3% reported alcohol use in last 30 days. The lack of parental supervision was associated with increased use of alcohol. The proportion of alcohol use was higher for girls, and also among those who were older than 16 years, worked, did not live with one or both parents, and lived in the South, regardless of sex. Conclusion: The results showed early alcohol experimentation and occurrence of problems due to its use among Brazilian adolescents. In addition, the lack of monitoring by parents and guardians shows a risk of alcohol use in this age.

title: Ensino de Geociências na universidade

description: ABSTRACT In colonial times, in Brazil, although intense mining activities occurred in the search for gold and diamonds, relevant geoscientific actions did not occur. In the 19th century, a few geological exploratory trips were made, from which several written contributions resulted. Moreover, important institutions were created, such as the National Observatory, the Meteorological Service, the Magnetic Observatory at Vassouras and the Mining School of Ouro Preto in 1876, The formal teaching of Geosciences in Brazil started only in 1957, with the ”Campaign for the training of geologists” (CAGE), that created and provided material and human resources to four Geology undergraduate courses. In Meteorology the first course was in 1973, in Oceanography in 1971 and in Geophysics in 1983. Now, 48 Brazilian universities offer 71 undergraduate courses in Geosciences, 33 in Geology, 3 in Geological Engineering, 14 in Meteorology, 13 in Oceanography and 8 in Geophysics. Fifty-seven graduate programs exist in Brazil, 13 of which are considered of excellence, indicating that the area is mature and consolidated. Most geologists and geophysicists were absorbed in geological mapping activities, as well as mining and oil exploration. Meteorologists dedicated themselves to meteorological and climatic monitoring, as well as to projects in hydroelectric, wind and solar energy. Graduates in Oceanography worked in institutions related to the environment, agriculture, and to the Ministry of the Navy. The atmospheric and oceanographic sciences are of global relevance in studies of climatic changes and global warming. In turn, the major challenge of geologists and geophysicists is to improve knowledge of the Brazilian territory, at the local and regional scale.

title: Glucose as a cause of and treatment for cutaneous necrosis

description: Abstract Sclerotherapy remains one of the procedures most frequently performed by Brazilian vascular surgeons. Knowledge of its complications is indispensable to enable us to avoid them. The severe side effects of this method of treatment for telangiectasias of the lower limbs are rare and are often associated with technical errors or the dose injected. Complications are predominantly local, but are sometimes difficult to resolve. We report a case of formation of cutaneous necrosis after chemical sclerotherapy using hypertonic glucose (75%), which healed when treated with a topical preparation containing vaseline and 60% glucose, with satisfactory esthetic results.
