“…Studies conducted in Brazil also showed the same results in the last decade, a high percentage of individuals in adolescence presenting several health risk factors such as abdominal obesity (32%), hypertension (15%), metabolic syndrome (7, 7%) [8][9][10] . Childhood and adolescence are important stages for the development of a healthy lifestyle, since most habits acquired during this period of life are perpetuated into adulthood 11 .…”

-The aim of this study was to systematically review studies on intervention programs involving physical activity promotion and/or nutritional education to reduce health-related risk factors (overweight/obesity and metabolic profilealterations) in Brazilian adolescent students. A search was performed in the following electronic databases: Medline (PubMed), Lilacs, Embase, Scielo and Capes Thesis Database. A total of 1,568 studies were identified, of which 21 full papers were analyzed and 5 were included in the systematic review. The majority of the studies involved physical activity practice combined with nutritional education in Brazilian adolescent students and all interventions showed positive effect on reducing health-related risk factors among Brazilian adolescents.It was concluded that all studies included in this review showed positive alterations in healthrelated risk factors after interventions, reinforcing the importance of intervention programs to promote a healthier lifestyle and reduce health-related risk factors in adolescents.

Foi realizada busca nas bases de dados eletrônicas Medline (PubMed), Lilacs, Embase, Scielo e Banco de Teses da Capes. Identificaram-se 1.568 estudos e 21 textos completos foram analisados, dos quais, cinco foram incluídos na revisão. A maioria dos estudos envolveu a prática de atividades físicas combinada à educação nutricional em diferentes regiões do país e todas as intervenções mostraram efeitos positivos na redução de fatores de risco à saúde. Conclui-se que todos os estudos nesta revisão demonstraram alterações positivas após as intervenções, mesmo que não significativas estatisticamente, reforçando a importância de programas de intervenção para a promoção de uma vida mais saudável e para reduzir os fatores de risco à saúde, em adolescentes.

“…Elevated prevalence of these health risk factors has also been reported in other studies with Brazilian adolescents [41][42][43] . We observed a reduction in total and daily ST, however there were no significant differences in the electronic aspect, corroborating a study by Dewar et al 39 , which did not find significant differences in adolescents' screen time after 12 months of intervention.…”

-Aim:To ascertain the effects of an after-school intervention on physical activity levels and cardiovascular risk factors in adolescents from Campinas, Brazil. Methods: This was an intervention study with 71 adolescents that was carried out in two schools, randomly assigned to a control group (CG:n=45) or an intervention group (IG:n=26).We performed evaluations of body composition, sexual maturation, blood pressure, level of physical activity, sedentary time (ST), and eating habits, as well as biochemical variables by a portable analyzer. The IG participated in two weekly sessions of physical activities and controlled physical exercises for 14 weeks. The sessions lasted 60', and were divided into warm-up (5-10'), main part (40-50'), and recovery (5-10'). Results: 30.8% of the IG and 24.4% of the CG were classified as overweight/obese. Additionally, the IG showed significantly lower ST (total: p=0.037; daily:p=0.009) after the intervention, as well as in the post-period (total ST: p=0.043; daily ST: p=0.007). The IG showed a reduction in glycemia (p=0.025). Conclusion: The intervention program generated positive changes in glycemia levels and ST. These results suggest that interventions involving physical exercise should be promoted in the school environment, as physical activity is an important component of a healthy lifestyle.

Objective: To estimate the burden of weight excess in Brazilian adolescents. Design: Systematic review with meta-analysis. Setting: We searched the literature in four databases (MEDLINE/PubMed, EMBASE, SciELO and LILACS). Studies were included if they had cross-sectional or cohort design and enrolled Brazilian adolescents. Studies based on self-reported measures were excluded. Random effect models were used to calculate prevalence estimate and its 95% confidence interval (95%CI). Participants: Brazilian adolescents (10 to 19 years old). Results: One hundred and fifty-one studies were included. Trend analyses showed a significant increase in the prevalence of excess weight in the last decades: 8.2% (95%CI:7.7-8.7) until year 2000, 18.9 (95%CI:14.7-23.2) from 2000 to 2009, and 25.1% (95%CI:23.4-26.8) in 2010 and after. A similar temporal pattern was observed in the prevalence of overweight and obesity separately. In sensitivity analyses, lower prevalence of excess weight was found in older adolescents and those defined using IOTF cutoff points. The Southeast and South regions had the highest prevalence of excess weight, overweight and obesity. No significant difference in prevalence by sex was found, except for studies before the year 2000. Conclusions: The prevalence of overweight and obesity in Brazilian adolescents is high and continues to rise. Public policies on an individual level and targeting modifications in the obesogenic environment are necessary.
