Abstract
School-based interventions are needed due to the low levels of physical activity (PA) in adolescents. The aim is to examine the mediation effects of psychosocial factors (attitude, self-efficacy, social support from parents, friends, general teachers, and PE teachers, and environment school perception) and moderation by sex, school grade, and socioeconomic level of a school-based PA intervention on the PA practice among adolescents. The Movimente Programme is a randomised controlled trial at schools in southern Brazil (n = 921 adolescents). Strategies included teacher training, educational actions, and environmental changes. Adolescents self-reported their weekly PA. Potential psychosocial mediators and moderators were investigated through validated questionnaires in a Brazilian sample. The product of the coefficients with percentile bootstrapping 95% confidence interval was performed. The Movimente Programme was related to positive changes in adolescents' perception of the school environment and social support from general and physical education teachers. Most psychosocial variables (attitude, self-efficacy, social support from friends, and social support from teachers) were associated with PA, but none mediated the impact of the Movimente Programme on PA. Results varied according to sex and school grade. The Movimente Programme increased the adolescents' perception of the school environment and social support from teachers, but no mediators were confirmed.

Abstract
Objectives: Little is known about the association between specific types of screen time and adolescents' substance use. Thus, this study aimed to investigate the associations between screen time for studying, working, watching movies, playing games, and using social media and frequency of alcohol and tobacco use. Methods: In this cross-sectional study, Brazilian adolescents answered survey questions related to frequency of tobacco and alcohol consumption, and reported their daily volume of five types of screen time. Multilevel ordered logistic regression models were performed. Results: Each 1-hour increase in ST for studying was associated with 26% lower odds of smoking (OR = 0.74; 95% CI: 0.61-0.90) and 17% lower odds of drinking alcohol (OR = 0.83; 95% CI: 0.76-0.91) in the past 30 days. The increase of 1 hour of social media use was associated with 10% greater odds of smoking (OR = 1.10; 95% CI: 1.02-1.18) and a 13% greater chance of consuming alcohol (OR = 1.13; 95% CI: 1.08-1.18) in the past 30 days. Conclusion: The association between screen time and substance use appears to be type-specific. Future longitudinal research is needed to explore causal relationships.

Abstract
Only a small proportion of Brazilian adolescents practice sufficient physical activity (PA). However, it is not clear whether this proportion has been decreasing over time. This study aimed to examine the 10-year trends of sufficient PA in adolescents and to investigate differences by sex and age. Using a standard protocol, we compared two cross-sectional cohorts of adolescents aged 15 to 18 years, recruited in 2007 (n = 1040) and in 2017/18 (n = 978). Using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the adolescents reported moderate-to-vigorous PA (MVPA) performed in the last seven days. Sufficient PA was defined as engaging in at least 60 min/day of MVPA. In the subgroups, investigated by sex or age, there was an increase in the prevalence of sufficient PA. Overall, sufficient PA declined by 28.1% from 2007 to 2017/18. Boys in 2007 were more active than their 2017/18 peers, and this was equally observed in girls in 2007 compared to those in 2017/18. The findings show decreasing secular trends in sufficient PA in the investigated adolescents. Not only are public health authorities in Brazil witnessing an escalation of insufficient PA, but they are also losing ground with the most active adolescents.

Abstract
OBJECTIVE To examine the socioeconomic indicators associated with engagement in physical activity (PA) in the leisure-time, transportation, domestic and occupational domains, in Brazilian adults. METHODS Cross-sectional study with secondary data from the National Health Survey (PNS), conducted in 2019. The factors associated with engagement in PA were analyzed using logistic regression. RESULTS The study involved 88,500 Brazilian adults with mean age of 45 ± 17.5 years old. Longer working hours [odds ratio (OR) = 0.74; 95%CI 0.66;0.82; > 40h vs. ≥ 20h] and female sex (OR = 0.67; 95%CI 0.63;0.71) were associated with lower chances of engaging in leisure-time PA. Higher income (OR = 3.20; 95%CI 2.79;3.67; > 5 vs. ≥ minimum wage) and education level (OR = 3.01; 95%CI 2.74;3.32 - complete higher education vs. incomplete elementary school) were positively associated with leisure-time PA. CONCLUSION Socioeconomic correlates were strongly related to engagement in PA in Brazilian adults, suggesting a pattern of inequity marked by the need for survival, which is socially reproduced.

Abstract
In this study, we evaluated socioeconomic inequalities in the consumption of in natura/minimally processed and ultra-processed foods among adolescents. We used data from the Brazilian National Survey of School Health (PeNSE), 2015. According to the self-reported consumption of beans, vegetables and fruits, a score of in natura/minimally processed foods was generated (0-21 points). Sodas, sweets, instant noodles, and ultra-processed meat were used for the score of ultra-processed foods (0-21 points). Equality indicators were gender, maternal education, and socioeconomic level. Absolute difference, ratios, concentration index and slope index of inequality were calculated. Adolescents (n=101,689, 51% girls, 14.2 years) reported a mean score of 9.97 and 11.46 for ultra-processed foods and in natura/minimally processed foods, respectively. Absolute and relative differences between adolescents with the highest and lowest socioeconomic level, there were differences of 2.64 points and 33% for consumption of in natura/minimally processed foods; and 1.48 points and 15% for ultra-processed foods. Adolescents from higher socioeconomic level ate more in natura/minimally processed foods and ultra-processed foods.

Abstract
This article aims to compare the prevalence of active commuting to work in adults in the Southern region of Brazil between 2006 and 2016 according to sociodemographic and labor characteristics. The data from the Brazilian System for the Surveillance of Risk and Protection Factors for Chronic Diseases - VIGITEL were compared in 2006 and 2016 (≥18 years). Active commuting to work, sex, age group, education and job characteristics were collected by telephone survey and transportation in the cities of Florianópolis, Curitiba and Porto Alegre, using absolute and relative frequencies with their respective 95% confidence intervals. Active commuting increased significantly in 2016 compared to 2006. Florianópolis had the highest prevalence in the two years analyzed. In all capitals, there was a significant increase in the prevalence of the outcome, mainly for women, with secondary education and only in Florianópolis for men, with low schooling. The prevalence has also increased for job characteristics in all capitals. Active commuting to work increased significantly among adults living in southern Brazil, with emphasis on Florianópolis. Expanding interventions in this context is a necessity in Brazil.

Abstract
OBJECTIVE The present study aimed to analyze the association of 2-year changes in BMI and waist circumference with changes in blood pressure (BP) in a randomized sample of community-dwelling adults. METHODS A sample of 331 middle-aged and older adults (mean age of 59.6 ± 17.3 years) was randomly selected. Measurements of SBP and DBP, BMI, and waist circumference were collected at baseline and after 2-year follow-up. Chronological age, sex, socioeconomic status, ethnicity, and self-reported medical diagnosis and use of medication for hypertension, diabetes, and high low-density lipoprotein-cholesterol were covariates. Multiple linear regression models were adopted for statistical analysis. RESULTS SBP was positively associated with BMI (β = 0.48, P = 0.013) and waist circumference (β = 0.21, P = 0.005) at baseline and only with waist circumference at follow-up (β = 0.20, P = 0.007). DBP was positively associated with BMI (β = 0.31, P = 0.009) and waist circumference (β = 0.12, P = 0.006) values at baseline and at follow-up (BMI β = 0.42, P = 0.001; waist circumference β = 0.18, P = 0.001). Only the 2-year changes in waist circumference were associated to changes in SBP (β = 0.33, P = 0.013), regardless of confounding factors and BMI. CONCLUSION It is suggested that waist circumference is the main factor for control over the time in strategies focused on BP management in adult population.

Abstract
BACKGROUND Little is known about how the interplay among health-related behaviors impacts self-rated health (SRH). We examined the clustering of physical activity (PA), sleep, diet, and specific screen-based device use, and the associations between the emergent clusters and SRH among Brazilian adolescents. METHOD The data used in this cross-sectional study were from the baseline of the Movimente Program. Self-reported data were analyzed. SRH was recorded as a 5-point scale (from poor to excellent). Daily duration of exposure to the computer, the television, the cell phone, and games; PA; sleep; and weekly consumption of fruits and vegetables and ultra-processed foods were included in a Two-Step cluster analysis. Multilevel ordered logistic regressions assessed the associations between the clusters and SRH. RESULTS The data of 750 students (girls: 52.8%, 13.1 ± 1.0 years) were analyzed. Good SRH was more prevalent (52.8%). Three clusters were identified: the Phubbers (50.53%; characterized by the longest cell phone use duration, shortest gaming and computer use, lowest PA levels, and low consumption of fruits and vegetables), the Gamers (22.80%; longest gaming and computer use duration, PA < sample average, highest intake of ultra-processed foods), and a Healthier cluster (26.67%; physically active, use of all screen-based devices < sample average, and healthier dietary patterns). For both Gamers (-0.85; 95% CI -1.24, -0.46) and Phubbers (-0.71; 95% CI -1.04, -0.38), it was found a decrease in the log-odds of being in a higher SRH category compared with the Healthier cluster. CONCLUSION Specific clusters represent increased health-related risk. Assuming the interdependence of health-related behaviors is indispensable for accurately managing health promotion actions for distinguishable groups.

Abstract
Background The objective of this study was to verify the reliability, discriminatory power and construct validity of the Kidscreen-27 questionnaire in Brazilian adolescents.
Methods Adolescents that participated of the pilot study (210 adolescents; 52.9% boys; 13.7 years old) and of the baseline (816 participants; 52.7% girls; 13.1 years old) of the Movimente Project in 2016/2017 composed the sample of the present study. This project was carried out in six public schools in the city of Florianópolis, Santa Catarina, Brazil. Test–retest reproducibility was assessed by the intraclass correlation coefficient and Gwet coefficient; internal consistency through McDonald's Omega; Hankins' Delta G coefficient verified the scale's discriminatory power and; confirmatory factor analysis to assess construct validity. Results Reproducibility values ranged from 0.71 to 0.78 for the dimensions (ICC), and ranged from 0.60 to 0.83 for the items (Gwet). McDonald's Ômega (0.82–0.91) for internal consistency measures. Discriminatory power ranging from 0.94 for the dimension Social Support and Friends to 0.98 for Psychological Well-Being. The factorial loads were > 0.40, except for item 19 (0.36). The fit quality indicators of the model were adequate (X2[df] = 1022.89 [311], p < 0.001; RMSEA = 0.053 (0.049–0.087); CFI = 0.988; TLI = 0.987), confirming the five-factor structure originally proposed. Conclusions The Brazilian-version Kidscreen-27 achieved good levels of reproducibility, internal consistency, discriminatory power and construct validity. Its use is adequate to measure the health-related quality of life of adolescents in the Brazilian context.

We aimed to identify sociodemographic, dietary, and substance use factors associated with self-reported sleep duration, physical activity (PA), and sedentary behavior (SB) indicators in a sample of Brazilian adolescents. Adolescents (n = 731, 51% female, mean age: 16.4 years) answered a questionnaire. The volume of total PA, sports, non-sports, total SB, leisure-time SB, involuntary SB, sleep duration, dietary behaviors, sociodemographic, and substance use indicators were self-reported. Multilevel linear models were fitted. Females engaged in less total PA, sports, total SB, and leisure-time SB, but in more involuntary SB than males. Age was positively associated with non-sports and involuntary SB. Socioeconomic status was positively associated with total PA. Adolescents who lived with the mother only practiced more sports compared to those living with two parents. Unprocessed food was positively associated with total PA and sports. Processed food was inversely associated with total PA and non-sports, and positively associated with total SB and leisure-time SB. Alcohol use was positively associated with total PA, and tobacco smoking was negatively associated with total PA. No associations were observed for sleep duration. In conclusion, sociodemographic, dietary, and substance use factors are associated with the 24 h movement behaviors among Brazilian adolescents, and some associations are type specific.

Abstract
ABSTRACT Introduction Although the benefits of regular physical activity (PA) for adolescents are well-described in the literature, there is little evidence of the role of psychosocial aspects on levels of PA in this population. Objective To investigate the prevalence and sociodemographic factors associated with enjoyment of PA and preference for leisure-time activities in boys and girls. Methods A cross-sectional study, with 6529 adolescents (aged 15 to 19 years) enrolled in secondary education in public schools in the South of Brazil. Logistic regression was used to analyze the association between sociodemographic factors and the variables of interest, with data collection using a standardized questionnaire. Results Boys enjoyed (87.1%) and preferred (44.4%) PA more than girls (enjoyment: 79.2%; preference: 29.5%). Among the boys, enjoyment was associated with family income(OR3-5 wages=1.53; OR≥6 wages=1.62) and, among the girls, it was associated with age (OR19 years=0.28), occupational status (ORworkers=1.45), and income (OR3-5 wages=1.35). Preference was associated with age (OR19 years=2.48) and income (OR≥6 wages=0.70) among the boys and, among girls, it was associated with area of residence (ORrural=1.47) and occupation (ORworkers=1.31). Conclusion Boys (enjoyment: 87.1%; preference: 44.4%) had more positive attitudes toward PA than girls (enjoyment: 79.2%; preference: 29.5%), and some sociodemographic variables appear to be more closely associated with these attitudes than others. Enjoyment was associated with family income for boys, and with age, occupation and income for girls. Preference, in turn, was associated with age and family income for boys, and area of residence and occupational status for girls.

Abstract
abstract – This study aimed to summarize existing research examining the prevalence of adequate sleep duration or meeting sleep recommendations among Brazilian children and adolescents. A systematic review was conducted on eight databases. The criteria for inclusion were original research, samples including Brazilian children and adolescents (age 0–18), studies that reported variables regarding sleep duration using both objective or subjective measures, school- or population-based surveys with random sampling, and cross-sectional or cohort studies. Of the 54 articles included, only 27 used data from different studies. Most of the studies were conducted in the southern region (n = 17) with only two studies having a nationally representative sample. Two studies included children below age five, and the age group most investigated was adolescents (>10 years old). A majority of the studies used a self-reported questionnaire and showed variability in the cutoff point applied for adequate sleep duration with the most reported being ≥8 hours. The proportion of adolescents who met recommendations or had adequate sleep duration ranged from 15% to 89%. Among children, the prevalence ranged from 17% to 95%. The least variability was observed among toddlers, ranging from 93% to 95%. No consistent gender differences were observed among the gender-stratified groups of children and adolescents across the studies. It can be observed that, because of the wide range of results and the lack of data with national representativeness, the prevalence of sufficient sleep among young people aged below 18 remains undefined in Brazil.

Abstract
Understanding the dimensions of internal and external validities (e.g., using the RE-AIM model: Reach, Effectiveness/Efficacy, Adoption, Implementation, and Maintenance) of school interventions is important to guide research and practice in this context. The aim of this systematic review protocol is to synthesize evidence on the RE-AIM dimensions in interventions based on the Health Promoting School (HPS) approach from the World Health Organization (WHO) in Latin America. Studies of interventions based on HPS-WHO that were carried out in Latin America involving the population of 5 to 18-year-olds will be eligible. Searches in nine electronic databases, a study repository, the gray literature, and the retrieved articles' reference lists will be performed, without year or publication language limits. Study selection and data extraction will be conducted by independent researchers. Data on intervention implementation will be summarized in categories of HPS-WHO actions: (1) school curriculum, (2) changes in the social and/or physical environment of schools, and (3) actions with families and the community. A previously validated tool will be used to summarize the information on the dimensions of the RE-AIM model. The strengths and limitations of the included studies will be evaluated using the Critical Appraisal Skills Program (CASP) tool, and the confidence level of evidence will be assessed according to the GRADE CERQual tool.

Abstract
OBJECTIVE To identify and evaluate the effects of community-based interventions on the sedentary behavior (SB) of Latin American children and adolescents. METHODS A systematic review on community-based trials to reduce and/or control SB in Latin American countries (Prospero: CRD42017072157). Five databases (PubMed, Web of Science, Scopus, SciELO and Lilacs) and a reference lists were searched. RESULTS Ten intervention studies met the eligibility criteria and composed the descriptive synthesis. These studies were conducted in Brazil (n=5), Mexico (n=3), Ecuador (n=1) and Colombia (n=1). Most interventions were implemented in schools (n=8) by educational components, such as meetings, lessons, and seminars, on health-related subjects (n=6). Only two studies adopted specific strategies to reduce/control SB; others focused on increasing physical activity and/or improving diet. Only one study used an accelerometer to measure SB. Seven studies investigated recreational screen time. Eight studies showed statistically significant effects on SB reduction (80%). CONCLUSIONS Latin America community-based interventions reduced children and adolescents' SB. Further studies should: define SB as a primary outcome and implement strategies to reduce such behaviour; focus in different SBs and settings, other than recreational screen time or at-home sitting time; and use objective tools together with questionnaires to measure sedentary behaviour in.

Abstract
This study aimed to investigate the association between simultaneity of leisure-time physical inactivity and high television time with the presence of chronic diseases in adults and older adults in Brazil. We analyzed secondary data from Vigitel 2013 database, a cross-sectional national survey. It was included 37 947 adults (18-59 years) and 14 982 older adults (≥60 years) living in Brazilian state capitals. The association was between simultaneity of risk behaviors considering leisure-time physical inactivity (<10 min/day) and high television time (≥2 h/day), with the presence of chronic diseases (diabetes, dyslipidemia, hypertension and obesity), measured according to the age group. We performed a binary logistic regression, crude and adjusted analysis, using weighted to reflect population estimates. In adults, there was an association between leisure-time physical inactivity and television time with the presence of diseases. In practice, the simultaneity of risk behaviors when compared with those without risk behavior had higher odds for diabetes (OR = 1.83), dyslipidemia (OR = 1.17), hypertension (OR = 1.54) and obesity (OR = 1.60). In older adults, the simultaneity was associated with diabetes (OR = 1.61), hypertension (OR = 1.33) and obesity (OR = 1.81). We concluded that for adults and older adults the simultaneity of leisure-time physical inactivity and high television time increased the odds for the presence of chronic disease, especially for diabetes and obesity.

Abstract
Abstract This study aimed to investigate whether attitudes towards body weight dissatisfaction is associated with perceived health and impairments in sleep among a national population-based sample of Brazilian adolescents. This is a cross-sectional data from the 2015 National School-Based Health Survey (PeNSE). A total of 100.182 students (70.8% were between 14 to 15) in ninth-grade, enrolled in public and private schools were eligible for data analysis. Variables were measured using a questionnaire and binary logistic regression was used. There was association between attitudes towards body weight dissatisfaction and perceived health (not controlling weight = OR: 2.19, 95%CI: 2.00-2.40; trying to lose = OR: 1.90, 95%CI: 1.75-2.05; gain = OR: 2.22, 95%CI: 2.01-2.46; maintain = OR: 1.81, 95%CI: 1.54-2.14). Adolescents were also more likely to present impairments in sleep (not controlling weight = OR: 1.21, 95%CI: 1.11-1.32; trying to lose = OR: 1.16, 95%CI: 1.08-1.25; gain = OR: 1.43, 95%CI: 1.28-1.61; maintain = OR: 1.43, 95%CI: 1.22-2.68). Dissatisfaction is an additional concern in the daily life of adolescents, which is associated to depreciation of the quality of sleep and decrement of psychological well-being.

Abstract
This study aims to analyse the association between perceived presence of public spaces near residences and practice of physical activity during leisure time by adults in the state capitals of Brazil, based on sociodemographic characteristics. Participants were individuals aged ≥18 years living in the 27 state capitals of Brazil (n = 52 929, 53.9% female) who responded to a national survey called VIGITEL in 2013. Physical activity during leisure time (≥1 time/week), perception of space, population and sociodemographic variables (sex, age, years of study and geographic region) were self-reported. The adjusted binary logistic regression analysis was used. Among adults, the prevalence of physical activity during leisure was 45.1% (95% CI [44.2; 46.0]), and 71.1% (95% CI [70.2, 71.8]) perceived public space near their residence. A direct association between perceiving public space and physical activity ([OR] = 1.43; 95% CI [1.32; 1.55]) was observed. No significant difference was observed in the population groups (men and women, younger and older adults, and those with more and fewer years of study). Thus, even with the possible regional differences in Brazilian state capitals, the presence of public spaces increases the practice of physical activity during leisure time, independent of sociodemographic variables.

Abstract
Resumo Compreender mudanças no consumo de frutas e verduras por adolescentes é importante para criação de ações de saúde pública. O objetivo deste artigo é investigar mudanças, em dez anos, no consumo diário de frutas e verduras por adolescentes, de acordo com sexo, idade e área de moradia. Estudo de painel (análise secundária) da pesquisa "Estilo de vida e comportamentos de risco de jovens catarinenses". Adolescentes (15-19 anos) de escolas estaduais, em 2001 (n = 5.028) e 2011 (n = 6.529), responderam questionário sobre consumo de frutas e verduras e aspectos sociodemográficos. Estatística descritiva e regressão logística (2001 vs 2011), estratificada para sexo, idade e área de moradia. Houve diminuição no consumo diário de frutas (39,1% e 16,6%) e de verduras (40,1% e 20,6%). Diferentes prevalências são observadas de acordo com subgrupos, principalmente entre moças. A chance para consumo diário de verduras entre rapazes e adolescentes de área rural continuou a mesma. A diminuição na prevalência do consumo diário de frutas e verduras por adolescentes catarinenses de 15 a 19 anos aponta necessidade de criação de estratégias para reversão deste cenário.

Abstract
OBJECTIVE To determine the prevalence of smoking, as well as its association with sociodemographic factors, alcohol consumption, and stress levels, among industrial workers in Brazil. METHODS This was a nationwide survey, conducted in 24 capitals in Brazil through the application of a pre-tested questionnaire. The response to the question "What is your smoking status?" was the outcome variable. To determine the associations, we performed Poisson regression analyses in which the inputs were blocks of variables: block 1 (age and marital status); block 2 (level of education and gross family income); block 3 (geographic region); and block 4 (alcohol consumption and stress level). All analyses were stratified by gender. RESULTS The sample consisted of 47,328 workers ≥ 18 years of age, of whom 14,577 (30.8%) were women. The prevalence of smoking was 13.0% (15.2% in men and 7.9% in women). Advancing age, alcohol consumption, and a high stress level were positively associated with smoking. A lower risk of smoking was associated with being married, having a higher level of education, and living in the northeastern region of the country (versus the southern region). CONCLUSIONS The prevalence of smoking was greater in men than in women. Alcohol consumption and high stress levels appear to promote smoking.

Abstract
Abstract The association of moderate to vigorous physical activity and sedentary behavior performed in the school context with cardiovascular risk factors is unclear. Thus, the purpose of this study was to evaluate whether MVPA and SB during school time are associated with single and clustered cardiovascular risk factors in 10- to 16-year-old school students. This study used the baseline data from a non-randomized controlled clinical trial (“MEXA-SE”) conducted on 6th to 9th-grade students from schools in Florianopolis, Brazil. Skinfolds, resting blood pressure, 20-m shuttle-run test, fasting glucose, triglycerides, total cholesterol, high-density lipoprotein cholesterol, and white blood cell counts were obtained. MVPA and SB were objectively measured with accelerometers. A minimum of 180 minutes was considered valid school-time for analysis. Multiple linear regression adjusted for age, sex and habitual physical activity was used. School-time MVPA was positively associated with the peak VO2 (β = 0.17 ml.kg.min-1), and inversely associated with sum of four skinfolds (β = -0.96 mm), diastolic blood pressure (β = -0.36 mmHg), systolic blood pressure (β = -0.301 mmHg); triglycerides (β = -1.49 mg.dL-1), and clustered cardiovascular risk factors (β = -0.123). School-time SB was positively associated with clustered cardiovascular risk factors (β = 0.033). In conclusion, independently of habitual physical activity level, school-time MVPA and a lower time in SB were associated to single and clustered cardiovascular risk factors. Thus, the promotion of strategies aimed increase MVPA and reduce SB at school may prevent the onset and early accumulation of cardiovascular risk factors in adolescence.

Abstract
INTRODUCTION This study evaluated the effect of an intervention on the engagement in physical activity (PA) and sedentary behavior (SB) of sixth to ninth grade students during school-time, physical education (PE) classes, and recesses at two public schools in Florianopolis, SC, Brazil. METHOD Schools were divided into control and experimental groups. Participants wore accelerometers during school-time, and PA and SB were estimated for school-time, PE classes and recesses at the baseline and after the intervention. The intervention was composed of four components: changes were made in the PE classes, including giving instruction to teachers; sports equipment was made available for use during recesses; educational sessions on the format of classes were conducted; folders and posters were distributed. Data was analyzed using an Analysis of Covariance for repeated measures comparing baseline data with post intervention data, and for independent samples when comparing control and intervention groups. RESULTS A low proportion of engagement in PA and a large engagement in SB was observed on the baseline. PA decreased in the intervention group during PE classes, while it increased in the control group with regard to school-time, PE classes, and recess. The intervention group accumulated more SB during school-time and PE classes after the intervention, while a decrease in the control group's SB during school-time was observed. CONCLUSION The intervention was not effective in increasing PA or decreasing SB. Environmental and school's organizational factors impact how interventions are conducted, and should be considered beforehand.

Abstract
The aims were to examine changes in the prevalence of overweight and obesity among students from 2001 to 2011, and to verify if these changes differ according to age group, area of residence, and family income. We analyzed two cross-sectional surveys conducted in 2001 and 2011 with brazilian adolescents. Sociodemographic and anthropometric characteristics were self-reported using a questionnaire. Multinomial logistic regression was used to analyze changes in overweight and obesity between the two surveys. The nutritional status was the outcome of the present study and the surveys (2001 and 2011) were the exposure. The odds of being overweight and obese were higher among boys and girls in urban areas in the 2011 survey compared to the 2001. Boys and girls with higher income were also more likely to present overweight and obesity in the second survey compared to the first. An increase of overweight and obesity was observed over a decade. We suggest that future interventions consider the area of residence and the family income to strengthen the effectiveness of actions developed to prevent and control these indicators among adolescents.

Abstract
Promoting healthy lifestyle factors (e.g., physical activity, healthy eating, less screen time) among young people is a relevant and challenging step toward reducing non-communicable diseases. This study aimed to evaluate the effect of a multicomponent intervention on lifestyle factors among adolescents from schools in low Human Development Index (HDI < 0.500) areas. The Fortaleça sua Saúde program was conducted with 548 adolescents aged 11–18 years old in the intervention group and 537 in the control group. The four-month intervention included strategies focused on training teachers, new opportunities for physical activity in the school environment, and health education strategies for the school community (including parents). Moderate- to-vigorous physical activity level (≥420 min/week), TV watching and computer use/gaming (<2 h/day), daily consumption of fruit juice, fruit, vegetables, soft drinks, savory foods and sweets, and current alcohol and tobacco use were measured before and after intervention. McNemar’s test and logistic regression (odds ratio [OR] and a 95% confidence interval [95% CI]) were used, considering p < 0.05. In the intervention schools, a significant increase occurred in the number of adolescents who met physical activity guidelines (5.3%; 95% CI = 0.8; 9.8) and who reported using computer for <2 h a day (8.6%; 95% CI = 3.8; 13.4) after intervention. No changes were observed in the control schools. At the end of the intervention, adolescents from intervention schools were more likely to practice physical activity at recommended levels (OR = 1.44; 95% CI = 1.00; 2.08) than adolescents from control schools. No significant change was observed for the other lifestyle factors. In conclusion, this multicomponent intervention was effective in promoting physical activity among adolescents from vulnerable areas. However, other lifestyle factors showed no significant change after intervention. This study is registered at Clinicaltrials.gov NCT02439827.

Abstract
This study analysed physical activity (PA) and sedentary behaviour (SB) performed in bouts during schooltime. Adolescents of two schools answered a questionnaire, had their height and weight measured and wore accelerometers during schooltime. Moderate-to-vigorous intensity PA was estimated in bouts of 2, 5 and 10 min, and SB in bouts of 5, 10, 30 and 60 min. Body mass index was calculated, and adolescents were classified as overweight or normal weight. Frequency, duration and volume of PA and SB were calculated for the whole sample and for those who performed at least one bout weekly. PA and SB differences between gender and weight status were tested using Mann-Whitney and t tests. A total of 415 adolescents (54% girls, 12.3 ± 1.3 years old, 34.6% overweight) performed 0.1 (± 0.2), 0.2 (± 0.5) and 0.4 (± 0.6) bouts of 10, 5 and 2 min of PA, and 10.6 (± 2.0), 6.0 (± 1.3), 1.1 (± 0.9) and 0.4 (± 0.5) bouts/day of 5, 10, 30 and 60 min of SB, respectively. Boys accumulated less SB and more PA in bouts. No differences were found for weight status.Conclusion: Adolescents hardly engaged in bouted PA and accumulated more SB in smaller bouts during schooltime. Bouted PA and SB were not associated with weight status. What is Known: • Adolescents are not engaging in enough PA and are accumulating large volumes of SB, which might negatively impact their health. • Schools play an important role in daily overall PA, with opportunities such as PE classes and recesses. But most classes are still undertaken in seated positions. What is New: • Adolescents hardly engage in bouted (> 10 m) PA when at school., and most SB is accumulated in short bouts (≤ 10m). • Weight status was not associated with bouted PA or SB at school.

Abstract
O presente estudo tem por objetivo estimar as prevalências dos tipos e das quantidades de atividades físicas (AF) realizadas no tempo de lazer por adolescentes, de acordo com sexo e idade. Participaram do estudo 6.529 estudantes (15-19 anos de idade) do ensino médio de escolas estaduais de Santa Catarina. Analisou-se a questão referente aos tipos de atividades realizadas no tempo de lazer. Comparados às moças, rapazes tiveram maiores prevalências de prática do futebol, da musculação e do ciclismo. Enquanto as moças praticaram mais a caminhada, a dança e a ginástica em relação aos rapazes. A caminhada foi a única atividade a diferir entre as idades. Conclui-se que os tipos de AF diferem de acordo com os sexos e as idades, enquanto a quantidade de AF diferiu apenas entre os sexos.Palavras Chave: Atividade Motora; Adolescente; Atividades de Lazer; Estudos Transversais

Abstract
The aim of this study was to identify evidence about the prevalence of the community and environment indicators related to physical activity (PA) among young Brazilian people. A systematic review was carried out using eight databases (PubMed, Scopus, Web of Science, LILACS, SPORTDiscus, BIREME, Scielo, and Google Scholar) with descriptors in Portuguese and English. Community and environment Indicators included access, presence, proximity, quality, safety and pollution of/in spaces, facilities, programs available for PA among young people (up to 18 years-old), which may be measured subjectively and/or objectively. A total of 23 documents were included, representing 15 different studies. There were more studies in the South region (n=8), followed by the Northeast (n=3) and Southeast (n=3). Self-reported instruments were more frequently used (n=15). The studies reported prevalence of perception (positive and/or barrier) for access to facilities, programs and/or parks (n=13); presence of sidewalks and bicycle lanes (n=4); proximity to residence (n=5); quality (n=5); safety from crime and traffic (n=14) and pollution (n=6); number of spaces and/or facilities around the residence (n=1); and observation of adolescents using public spaces for PA (n=3). The prevalence rates showed high variability according to environmental indicator. No studies are available for the North and Midwest of the country. Distinct environmental measures were used in selfreported studies, impairing data comparability. To date, no studies have been identified that provide information about the prevalence of combined environmental measures (perceived and objective).

Abstract
The aim of this study was to summarize studies examining the prevalence of sedentary behavior among Brazilian children and adolescents. A systematic review conducted on eight databases (PubMed, Scopus, Web of Science, LILACS, SPORTDiscus, BIREME, Scielo, and Google Scholar). The criteria applied were: original research; samples including Brazilian children and adolescents; to be a school- or population-based survey; observational studies using different measures of sedentary behavior; studies showing the prevalence of at least one component of sedentary behavior. Of the 205 studies included, 104 were analyzed. There was a greater concentration of studies in the southern (n=41) and northeastern (n=18) regions. The components more frequently investigated were watching TV (n=36) and screen time (n=32). Only three studies included children under seven years, and the age range more investigated was 10 to 19 years. Most of the studies used a self-reported questionnaire and showed variability in the cut-off point applied (from 2 to 4 hours/day). The prevalence of adolescents who met recommendations ranged from 9.4% to 68.0% for sedentary behavior (<2 hours/day) and from 16.8% to 67.2% for TV viewing (<2 hours/day). The prevalence ranged from 39.1% to 97.7% for computer use and from 47.7% to 98.0% for videogame use. Most of the studies reported that less than half of the adolescents met the recommendations of sedentary behavior and TV viewing. On the other hand, more than half of them devoted less than two hours a day to computer and videogame use.

Abstract
The aim of this study was to summarize data on the prevalence of global physical activity (PA) among children and adolescents in Brazil. This systematic review included an electronic search in 8 databases (PubMed, Scopus, Web of Science, LILACS, SPORTDiscus, BIREME, Scielo, and Google Scholar) and a manual search in the references of retrieved studies. Observational studies that assessed global PA among Brazilian children and adolescents were included. A narrative approach toward results was adopted. An initial database search reached 3276 potentially relevant titles (2534 titles after duplicate analysis); 92 (62 different studies) met all inclusion criteria. Studies were carried out between 2001 and 2015; most studies were conducted in Southern and Northeastern Brazil. Three were nationwide surveys (4.8%), but no studies included children aged 0-5 years. Eighteen different instruments for PA measurement were used; only two studies used objectively-measured PA. The most used definition was ≥ 300 minutes/week of moderate-to-vigorous PA. The overall proportion of young people who were physically active ranged from 6.5% to 92.3%. Fourteen studies (22.6%) found a prevalence of ≥ 50%. Three nationwide surveys reported the prevalence of physically active students ranging from 29.0% to 66.0%. A wide variability of PA estimates were found. Important research gaps (e.g., studies with objectively-measured PA, children aged up to 6 years-old and in Northern Brazil) should be considered to develop new research studies in Brazil.

Abstract
This study evaluated whether the relationship between socioeconomic status (SES) and moderate-to-vigorous physical activity (MVPA) is mediated by social support of peers and parents. A cross-sectional study included students (n = 1182) aged 11 to 18 years who were recruited in 2014 from public schools in Fortaleza, Brazil. Participants completed a questionnaire to assess all variables. Mediation analyses were performed to determine the role of parental support and peer support on the relationship between SES and MVPA. Also, moderated-mediation analyses with estimating of conditional indirect effects were performed in order to identify whether gender is a moderator of the mediating effect. A positive and significant association between SES and MVPA was found among Brazilian students, and social support of parents and peers were significant mediators of this relationship. Conditional indirect effects showed that both parental and peer support had a significant indirect effect among boys; only parental support had a significant indirect effect among girls. These results suggest that improving social support can help reduce the impact of SES on physical activity among Brazilian adolescents.

Abstract
The aims of the present study were to evaluate possible gender differences in the prevalence of physical aggression among adolescents, and to examine the association between sociodemographic factors and physical activity participation with physical aggression in boys and girls. The sample was composed of 6,529 high school students (aged 15-19 years) from public schools of the state of Santa Catarina. A questionnaire was applied to collect data regarding sociodemographic factors, involvement in physical aggressions and types of physical activity. Crude and adjusted binary logistic regression models were performed. Boys reported more involvement in physical aggression episodes (36.9%) compared to girls (26.0%, p<0.05). Boys who lived in urban areas (OR: 1.45) and did not live with the family (OR: 2.22), as well as girls enrolled in the night shift were more likely to engage in fights (OR: 1.26). Adolescents aged 17-19 years had reduced chances of getting involved in fights (OR Boys: 0.66; OR Girls: 0.80) compared to younger ones. The practice of team sports among boys (OR: 1.56) and the combined practice of team sports and individual physical activities among boys (OR: 1.91) and girls (OR: 1.36) were associated with physical aggressions. It was concluded that boys were more likely to engage in fights, mainly younger boys, who did not live with family and lived in urban areas. In boys and girls, the involvement in physical aggression was greater among those who are engaged in team sports.

Abstract
UNLABELLED Knowledge about the effects of school-based interventions on modifiable physical activity (PA) determinants (e.g., social support), and whether the intervention effect differs according to students' characteristics (e.g., age and gender) are relevant PA promotion topics. This study aims to answer these topics among Brazilian students. This cluster-randomized controlled trial was conducted with 548 students in the intervention group and 537 in the control group (51.5% of boys; aged 11-18years). The four-month intervention included strategies focused on training teachers, opportunities for PA in the school environment, and health education. Potential PA determinants (attitude, self-efficacy, support of friends, parents, and teachers, perceived neighborhood environment and PA facilities in school) and moderators (gender, age, socioeconomic status (SES), and PA level at baseline) were assessed using self-reported instrument. Height and weight were measured to estimate the students' body mass index (BMI) status. Generalized linear models were used. In general, there was a significant and positive intervention effect for attitude, support of friends and teachers for PA, as well as PA facilities in school; effect size was 0.29, 0.24, 0.34, and 0.29, respectively (P<0.05). Age (support of friends, parents and teachers, and PA facilities in school), SES (support of friends and PA facilities in school), and BMI status (support of friends) were moderators of the intervention effect on some outcomes. In conclusion, the intervention improved potential PA determinants, but some changes occurred differently according to students' characteristics. These findings should be considered in PA policies in the school context. TRIAL REGISTRATION This study is registered at Clinicaltrials.govNCT02439827.

Abstract
Objective: Verify the prevalence and sociodemographic and economic factors associated with behavior change stages for habitual physical activity practice in adolescents from Santa Catarina. Methods: Secondary analysis of a study on the Behavior of Adolescents from Santa Catarina (CompAC 2). Cross-sectional school-based study of 6,529 high-school students (males, n=2,903) from the state of Santa Catarina public education system in 2011, aged 15 to 19 years. Multinomial logistic regression (crude and adjusted) was used to measure the association. Results: The highest and lowest prevalence rates were found in the maintenance (43.9%) and precontemplation stages (7.0%), respectively. The stages of action, preparation and contemplation showed similar results: 16.2%; 17.0% and 15.6%; respectively. Male adolescents show higher prevalence in the maintenance stage in relation to females and these show a higher prevalence in preparation, contemplation and precontemplation. All the assessed variables (gender, age, area of residence, employment status, family income, maternal education and school grade), with the exception of school shift, were associated with at least one of the stages. Conclusions: A large proportion of adolescents are in the pre-adoption stages and most of these have the intention to start regular physical activity. With the exception of school shift, the assessed variables were associated with stages in different ways, showing different profiles in relation to sociodemographic and economic characteristics in each subgroup.

Abstract
OBJECTIVE To investigate the moderating effect of gross family income on the association between demographic indicators and active commuting to work in Brazilian adults. METHODS Secondary analysis of the survey "Lifestyle and leisure habits of industry workers" (n=46,981), conducted in 24 Brazilian states (2006-2008). Self-reported information was collected with a previously tested questionnaire. Crude and adjusted logistic regression models were applied to analyze the association between sociodemographic variables (sex, age, marital status, number of children, education, country area and company size) and active commuting to work in different strata of gross family income. To test the moderating effect, an interaction analysis was applied. RESULTS The proportion of active commuters among low-, medium- and high-income workers was 40.7% (95%CI:40.0%;41.5%), 27.0% (95%CI:26.3;27.6%) and 11.1%, (95%CI:10.5%;11.7%), respectively. The moderating effect of gross family income was confirmed. Men were more likely (OR:1.22 95%CI:1.12;1.32) to commute actively than women among low-income individuals. Active commuting was less likely among older workers in low-(OR30-39:0.90 95%CI: 0.83;0.98; OR≥40: 0.76 95%CI: 0.68;0.85) and medium-income strata (OR30-39:0.87 95%CI:0.80;0.95; OR≥40:0.84 95%CI:0.76;0.93) and among married individuals in high-income strata (OR:0.72 95%IC:0.61;0.84). Adults with lower education (ORhigh:10.80 95%CI:8.47;13.77), working in the south (ORhigh:1.93 95%CI:1.53;2.44) and in small companies (ORlow:2.50 95%CI:2.28;2.74) were more likely to commute actively; however, the magnitude of these associations differed at each income strata. CONCLUSION There was an inverse association between gross family income and active commuting. Gross family income acts as a moderator of the association between demographic indicators and active commuting.

Abstract
RESUMO Objetivo A satisfação com a vida é um julgamento cognitivo de alguns domínios específicos na vida e depende de uma comparação entre as circunstâncias de vida do indivíduo e um padrão por ele estabelecido. O objetivo deste estudo foi construir uma escala de satisfação com a vida por meio da Teoria da Resposta ao Item (TRI). Métodos Para a criação da escala, foi utilizado o questionário “Estilo de Vida e Hábitos de Lazer de Trabalhadores da Indústria” e a Teoria da Resposta ao Item com base no modelo de resposta gradual proposto por Samejima. Participaram do estudo 47.477 trabalhadores brasileiros da indústria. Resultados A escala contou com sete itens do bloco de perguntas “indicadores de saúde e comportamentos preventivos”, com assuntos relacionados ao estado de saúde, qualidade de sono, nível de estresse, sentimento de tristeza ou depressão e percepção de vida no lar, no trabalho e no lazer. Conclusão São poucos os estudos que tiveram seu foco direcionado à satisfação com a vida no Brasil, e aqueles que de alguma forma o abordaram incluíram somente uma questão específica sobre felicidade ou satisfação de vida, principalmente em estudos sobre o bem-estar subjetivo. Os resultados mostraram que a TRI foi eficiente para criar a escala, medindo principalmente aqueles indivíduos com valores intermediários de satisfação com a vida.

Abstract
This study focused on the association between socio-demographic characteristics and three sedentary behaviors among industrial workers in Brazil. Data were analyzed on 47,477 workers from 24 Brazilian states, collected by questionnaires from 2006 to 2008. Individual and simultaneous presence of ≥ 4 hours of TV time per day, commuting by car or motorcycle, and sitting most of the time at work were investigated, as well as associations between these behaviors and gender, age, schooling, and family income. Simple and multiple binary logistic regression were used. Older workers and those with more schooling and higher income had increased odds of presenting two or all of the three target behaviors. Associations between gender and sedentary behaviors depend on the specific behavior. Such information can be useful for planning interventions to reduce sedentary behavior, with better targeting and more effectiveness in reaching different population subgroups.

Abstract
PURPOSE To investigate screen-time change from early to mid adolescence, its predictors, and its influence on body fat, blood pressure, and leisure-time physical activity. METHODS We used data from a longitudinal prospective study, conducted among participants of the 1993 Pelotas (Brazil) Birth Cohort Study. At baseline, adolescents were, on average, 11 years old. They were later visited at age 15 years. Screen time was self-reported, accounting for the time spent watching television, playing video games, and using the computer. Several predictors were examined. The effect of screen-time change on some health outcomes was also analyzed. RESULTS Screen time increased on average 60 min/d from 11 to 15 years of age, for the 4,218 adolescents studied. The groups that presented the highest increases in screen time were male, wealthiest, those whose mothers had higher education, and adolescents with a history of school failure. There were positive associations between screen-time change and body mass index, skinfold thickness, waist circumference, and leisure-time physical activity at 15 years of age. CONCLUSIONS Screen time increased from early to mid adolescence. This increment was higher among boys and the wealthiest adolescents. Increases in screen time affected body composition, with negative implications on adiposity.

Abstract
OBJETIVO: Estimar a prevalência e os padrões dos fatores de risco para doenças crônicas não transmissíveis segundo o nível socioeconômico e a idade dos adolescentes. MÉTODOS: Estudo transversal de base escolar envolvendo 1.675 adolescentes (53% do sexo feminino), com idades de 11 a 17 anos, de escolas públicas e privadas. O consumo de tabaco e álcool, o alto consumo de gordura na dieta e o baixo nível de atividade física constituíram as variáveis comportamentais. Circunferência da cintura e pressão arterial elevada, assim como e baixa aptidão cardiorrespiratória compuseram as variáveis biológicas. Regressão logística multinomial foi realizada para identificar variáveis associadas à simultaneidade dos fatores de risco para doenças crônicas não transmissíveis. RESULTADOS: Dos adolescentes, 62 e 31% apresentaram baixa aptidão cardiorrespiratória e elevado consumo de gordura, respectivamente. Dois em cada dez adolescentes tinha dois ou mais comportamentos de risco, e um terço deles tinham pelo menos dois fatores de risco biológicos para doenças crônicas não transmissíveis. No total, 62% dos adolescentes tinham pelo menos dois fatores de risco para doenças crônicas não transmissíveis, com maior frequência nos estudantes mais velhos. Na análise simultânea de todas as variáveis, observou-se que o aumento da idade esteve associado ao acúmulo de dois ou mais fatores de risco (sexo masculino com OR 2,10, e feminino com OR 5,74). CONCLUSÕES: Seis em cada dez adolescentes tinham pelo menos dois fatores de risco, enquanto a proporção do agrupamento desses fatores aumentou com a idade. Portanto, quanto mais precoce forem as intervenções, provavelmente menos adolescentes estarão acometidos por agravos à saúde em idades mais avançadas.

Abstract
OBJECTIVE To examine perceived poor sleep quality and its association with unhealthy lifestyle and self-reported morbidities among Brazilian workers. METHODS This study was part of a national survey involving 47,477 workers who received a questionnaire about lifestyle. Chi-square tests and logistic regression (OR=Odds Ratio) were conducted. RESULTS Poor sleep quality was reported by 21% of workers and was more prevalent among women (p<0.01). After being adjusted for socio-demographic indicators, negative perception of health, well-being, stress, self-reported morbidities, physical inactivity during leisure-time (OR: 1.18) in both genders, and inadequate fruit and vegetable intake (OR(men): 1.15; OR(women): 1.17), as well as excessive alcohol consumption (OR: 1.15) in men remained associated with poor sleep quality. With respect to morbidities, only diabetes in women (OR: 1.46) and hypertension in men (OR: 1.18) were associated with poor sleep quality. CONCLUSIONS Our findings indicate that certain unhealthy behaviors and self-reported morbidities were associated with poor sleep quality. Efficient initiatives should be implemented to promote a healthier lifestyle among workers, which could reduce or control glucose levels and blood pressure in addition to improving perceived sleep quality.

Abstract
OBJETIVO: Identificar a prevalência e os fatores associados à autopercepção negativa de saúde em adolescentes catarinenses. MÉTODOS: Foi realizado um estudo de delineamento transversal com adolescentes do ensino médio das escolas públicas do Estado de Santa Catarina (n=5.028). A autopercepção negativa de saúde foi analisada em função das variáveis: sexo, renda familiar, prática de atividade física, tabagismo, etilismo, drogas ilícitas e autopercepção de estresse. Aplicou-se a regressão logística binária para medidas de associação. RESULTADOS: A prevalência de autopercepção negativa de saúde foi maior nas moças (17,6%) em relação aos rapazes (9,6%; p<0,0001). Valores superiores de Odds Ratio (OR) foram observados para as moças (OR 1,99; IC95% 1,66-2,38), adolescentes pertencentes às famílias de menor renda (OR 1,54; IC95% 1,08-2,20), fumantes (OR 2,00; IC95% 1,35-2,94) e que referiram autopercepção negativa de estresse (OR 3,36; IC95% 2,74-4,12). CONCLUSÕES: Os adolescentes do sexo feminino, os de menor renda familiar, além dos fumantes e os que perceberam negativamente o estresse apresentaram níveis de autopercepção negativa de saúde superiores aos dos seus pares.
