This study aimed to identify the prevalence and factors associated with suicidal ideation among Brazilian adolescents. The instrument designed for the research was used considering three models with outcomes that identified the following: (a) adolescent had considered suicide, (b) adolescents have planned suicide, and (c) adolescents have attempted suicide. Logistic Regression was used in all models with significance level of 5%. An association between being female and suicidal ideation (OR = 2.18, CI 95% 1.60 to 2.97), suicide planning (OR = 1.80, CI 95% = 1.26–2.56), and suicide attempt (OR = 2.91, CI 95% 1.79 to 4.75) was found. Violent behavior/involvement in fights was associated with thinking about suicide (OR = 2.00, CI 95% = 1.43 to 2.81), suicide planning (OR = 1.65, CI 95% = 1.10–2.46), and suicide attempt (OR = 2.35, CI 95% = 1.49 to 3.70). For cigarette consumption, association was found with suicide ideation (OR = 1.62, CI 95% 1.03 to 2.55), planning (OR = 1.88, CI 95% = 1.15 to 3.08), and attempt (OR = 2.35, CI 95% 1.37 to 4.03). For alcohol consumption, association was found with suicide ideation (OR = 1.93, CI 95% 1.47 to 2.54), planning (OR = 2.22, CI 95% 1.61 to 3.08), and attempt (OR = 1.73, CI 95% 1.15 to 2.59). It was concluded that suicidal ideation was associated with female sex, involvement in fights, and illicit drug use.

The aim of this study was to identify prevalence and factors associated with violent behavior among adolescents in Aracaju and Metropolitan region. The study included 2207 adolescents (16.03 ± 1.08 years old) enrolled in high schools of the State Public Network. Violent behavior was identified from question 14 of the YRBS-2007 questionnaire with responses categorized as “never” and “one or more times.” Higher prevalence in males in relation to risk factors for adoption of violent behavior was found: cigarette consumption (7.3%), alcohol consumption (39.1%), and marijuana use (3.4%). Data analysis used descriptive statistics and logistic regression with hierarchical model at two levels: (a) sociodemographic variables and (b) behavioral variables. For both sexes, association between violent behavior and cigarette smoking (OR = 3.77, CI 95% = 2.06–6.92 and OR = 1.99, CI 95% = 1.04 to 3.81, male and female, resp.) and alcohol consumption (OR = 3.38, CI 95% = 2.22 to 5.16 and OR = 1.83, CI 95% = 1.28 to 2.63, male and female, resp.) was verified. It was concluded that violent behavior is associated with the consumption of alcoholic beverages and cigarettes among adolescents.

Design The social, cultural, and economic context can be an important variable in the perception and adoption of risk behaviors in adolescents. Objective The purpose of this study was to identify the prevalence of simultaneous health risk behaviors and associated socioeconomic factors in adolescents living in the metropolitan region of Aracaju, State of Sergipe, Brazil. Methods The sample consisted of 2,207 high school students aged 13–18 years. The risk behaviors measured were “low levels of physical activity,” “excessive daily TV time,” “high consumption of alcoholic beverages on a single occasion,” “involvement in fights,” “smoking cigarettes,” “carrying firearms,” and “marijuana consumption.” Information was obtained through self-administered questionnaire. Results Considering the results, it was observed that female adolescents and those aged up to 16 years were less likely to have two or more health risk behaviors compared to males and those aged 17 years or more, respectively. It was also found that both high- and middle-income level adolescents had higher prevalence of having two or more health risk behaviors. Conclusions It was concluded that male adolescents older than 16 years with better socioeconomic level were more exposed to the simultaneous presence of several health risk behaviors.

Resumo -Níveis de aptidão aeróbica de crianças e adolescentes estão declinando em todo o mundo, enquadrando-se em risco para a saúde. No Brasil, aproximadamente, 60% dos escolares apresentam níveis de aptidão cardiorrespiratória abaixo do recomendado para a idade e sexo. O objetivo foi verificar a influência da maturação sexual e do nível de atividade física na aptidão cardiorrespiratória em escolares de ambos os sexos com idade de 9 a 14 anos. O estudo foi transversal com amostra composta por 747 indivíduos (47,12% do sexo feminino) e idade de 9 a 14 anos, matriculados na rede pública de ensino. Os indivíduos responderam o PAQ-C e o questionário sobre maturação sexual, além de participarem do shuttle run test. Para verificar a influência no VO 2máx, os participantes foram categorizados em pré-púberes, púberes e pós-púberes e de acordo com o sexo e a interação (sexo vs maturação). Foi utilizada a ANOVA para comparar as médias dos estágios de maturação e para avaliar se o sexo e a maturação afetavam o VO 2máx . Houve influência da maturação (p < 0,0001; Eta 2 = 0,069; power = 1) e do sexo (p < 0,0001; Eta 2 = 0,059; power = 1) na aptidão aeróbica. O VO 2máx entre os estágios de maturação foi diferente entre os sexos. A maturação influenciou o VO 2máx com tendência decrescente e linear (p < 0,0001; Eta 2 = 0,221; power = 1) para o sexo feminino. Verificou-se influência da maturação e do nível de atividade física na aptidão cardiorrespiratória em escolares da cidade de Aracaju.

In Brazil, approximately 60% of the students present levels of fitness lower than recommended for age and sex. Our objective was to determine the influence of sexual maturation and physical activity level on cardiorespiratory fitness of schoolchildren of both sexes aged 9-14 years. This was a cross-sectional including a sample of 747 individuals (47.12% female) aged 9 to 14 years enrolled in public schools. The participants completed the Physical Activity Questionnaire for Children (PAQ-C) and a questionnaire on sexual maturation, and performed the shuttle run test. In order to verify the influence of sexual maturation on VO 2max , students were categorized according to maturation stage (prepubertal, pubertal and postpubertal), sex, and interaction between sex and maturation. ANOVA was used to compare mean maturation stages and to assess whether sex and maturation affect VO 2max. There was influence of maturation (p <0.0001; Eta 2 = 0.069, power = 1) and sex (p <0.0001; Eta 2 = 0.059, power = 1) on aerobic fitness. VO 2max values were different between the maturation stages in both sexes, and between sexes at the same maturation stage. Maturation influenced VO 2max with a decreasing linear trend (p <0.0001; Eta 2 = 0.221, power = 1) for females. An influence of maturation and physical activity level on cardiorespiratory fitness was observed in sch...

The present study aimed to verify the contribution of different physical activity domains to “total physical activity” in Brazilian adolescents. This is a cross-sectional study using secondary data from the third edition of the National School Health Survey - PeNSE, 2015. The sample consisted of 100,497 adolescents of both sexes enrolled in the 9th grade of elementary schools. A linear regression model was used to verify how much each domain contributed to total physical activity, considering gender, type of municipality and region. The domain with the largest contribution to “total physical activity” regardless of sociodemographic and environmental variables was “extra-school physical activity” (R2 = 0.60), followed by “active commuting” (R2 = 0.34), and finally “Physical Education classes” (R2 = 0.23). The contribution of the different domains varied by gender, type of municipality and region, and it was concluded that “extra-school physical activity” make the greatest contribution to “total physical activity”, followed by “active commuting” and “Physical Education classes”. In addition, variation was observed in the contribution of domains by gender, type of municipality and region.

Introduction. Several studies have pointed to the high prevalence of low levels of physical activity in adolescents, suggesting the need for more effective interventions for this group. The aim of this study was to present evidence of intervention programs for efficacy of physical activity for adolescents. Methods. Surveys in PubMed, SportDiscus, LiLacs, and SciELO databases were conducted using keywords to identify population, intervention, and outcome, as well as DeCS and MeSH terms in English, Portuguese, and Spanish, whenever appropriate. The review included observational studies with minimal intervention of six months, minimum sample size of 100 adolescents, written in any language, and those who have reached STROBE score greater than 70%. Results. Only seven studies met all inclusion criteria. Of these, five were pre- and postintervention and two had n > 2000 participants. Interventions were of several types, durations, and strategies for physical activity implementation. Behavior change was assessed in 43% of studies and three reported success in some way. Conclusion. Due to heterogeneity in their contents and methodologies, as well as the lack of jobs that accompany adolescents after the intervention period, one cannot draw conclusions about the actual effects of the intervention programs of physical activity on the behavior of young people.

Objective: The objective of this systematic review was to identify the effects of different training methods in women who have survived breast cancer (WSBC).Data Sources: Studies were identified by searching SportDiscus, Web of Science, PubMed, Scopus, Scielo, and Bireme.Study Selection: The inclusion criteria were articles that addressed only breast cancer in women, were randomized clinical trials, and interventions involving physical training with Consort ≥80.Data Extraction: The PICO and CONSORT strategies were used for the selection of articles and quality assessment of randomized clinical trials, respectively. Two independent reviewers searched for articles among the databases. Disagreements were discussed, and in the case of an impasse, a third reviewer was consulted.Data Synthesis: Evidence that demonstrated the beneficial effects of physical exercise programs carried out by WSBC. Moderate or high-intensity exercise sessions have been shown to benefit women survivors of breast cancer. Among the modalities, the resistance exercise showed effects from 55% of one-repetition maximum (1 RM), exclusively or associated with other training regimes, such as aerobic (from 48% of heart rate), high-intensity interval training (HIIT), or impact. The main benefits include increased muscle strength, promoted by the practice of resistance exercise in combination with other types of exercises or alone; decreased fatigue; improved quality of life; improved psychosocial effects, and increased leisure time.Conclusions: Physical training performed at a moderate or high intensity (aerobic or anaerobic) can reduce fatigue, improve quality of life, improve sleep quality, and increase bone mineral density in women survivors of breast cancer.
