Obesogenic behavior clusters associated with weight status among Brazilian students: a latent class analysis.

This study aimed to examine the association between clusters of physical activity (PA), diet, and television viewing (TV) with weight status among a representative sample of Brazilian students. Data from the National Health School-based Survey (PeNSE) 2015 were analyzed (n = 16,521; mean age 14.8, standard deviation 0.03 year). PA (minutes/week spent in leisure-time, and commuting to/from school), TV (hours/day), and weekly consumption of deep-fried empanadas, candies, sodas, ultra-processed foods, fast foods, green salads or vegetables, and fruits were self-reported on the validated PeNSE questionnaire. Latent class analysis defined behavior classes, and binary logistic regression assessed the association between clustering and weight status. Six classes' types with positive and negative behaviors were identified. Adolescents belonging to the "low TV time and high healthy diet" class had higher chances of being overweight (including obesity) compared to their peers in the "moderate PA and mixed diet" class. No associations were found in the other clusters. Mixed classes with healthy and unhealthy behaviors characterized adolescents' lifestyles and these profiles were related to weight status.

Resumo O estudo objetivou examinar a associação entre agrupamentos de atividade física (AF), dieta e tempo de televisão (TV) com o status do peso em uma amostra representativa de estudantes brasileiros. Foram analisados ​​dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) 2015 (n = 16.521; idade média 14,8, desvio padrão de 0,03 ano). AF (minutos/semana no lazer e deslocamento para/da escola), assistir televisão (TV) (horas/dia), consumo semanal de doces, refrigerantes, alimentos ultraprocessados/fast-foods, saladas/vegetais e frutas foram coletadas por questionário validado. Análise de classes latentes definiu os perfis de comportamento e a regressão logística binária a associação entre agrupamento e status de peso. Foram identificadas seis classes com comportamentos positivos e negativos. Adolescentes pertencentes à classe "baixo tempo de TV e alta alimentação saudável" apresentaram maior probabilidade de ter sobrepeso/obesidade em comparação com seus pares na classe "AF moderada e dieta mista". Não foram encontradas associações nos outros perfis. Classes com comportamentos saudáveis ​​e não saudáveis ​​caracterizaram o estilo de vida dos adolescentes e estiveram relacionadas com o status de peso.

A systematic review of the clustering and correlates of physical activity and sedentary behavior among boys and girls.

Identifying the clustering and correlates of physical activity (PA) and sedentary behavior (SB) is very important for developing appropriate lifestyle interventions for children and adolescents. This systematic review (Prospero CRD42018094826) aimed to identify PA and SB cluster patterns and their correlates among boys and girls (0-19 years). The search was carried out in five electronic databases. Cluster characteristics were extracted in accordance with authors' descriptions by two independent reviewers and a third resolved any disagreements. Seventeen studies met the inclusion criteria and the population age ranged from six to 18 years old. Nine, twelve, and ten cluster types were identified for mixed-sex samples, boys, and girls, respectively. While girls were in clusters characterized by "Low PA Low SB" and "Low PA High SB", the majority of boys were in clusters defined by "High PA High SB" and "High PA Low SB". Few associations were found between sociodemographic variables and all cluster types. Boys and girls in "High PA High SB" clusters had higher BMI and obesity in most of the tested associations. In contrast, those in the "High PA Low SB" clusters presented lower BMI, waist circumference, and overweight and obesity. Different cluster patterns of PA and SB were observed in boys and girls. However, in both sexes, a better adiposity profile was found among children and adolescents in "High PA Low SB" clusters. Our results suggest that it is not enough to increase PA to manage the adiposity correlates, it is also necessary to reduce SB in this population.

Obesogenic Clusters Associated with Weight Status in Brazilian Adolescents of the Movimente School-Base Intervention.

BACKGROUND: the relationship between behavior clusters and weight status, mainly in low- and middle-income countries, remains unclear. This study aimed to examine the association between profiles of physical activity (PA), diet and sedentary behavior (SB) with weight status in adolescents from a southern Brazilian city, according to sex. METHODS: data from the Movimente Intervention study were analyzed (n = 812 / mean age 13.0 years (sd 1.04). Data on SB hours per day, PA minutes per week and weekly consumption frequencies of fruits, vegetables, salty snacks, candies and soda were self-reported on the validated Movimente questionnaire. Classes of healthy and unhealthy behaviors were derived by latent class analysis. Logistic regression analysis was used to estimate the associations between adolescents' weight status and classes. RESULTS: two classes were identified for the whole sample and for boys and girls. All classes had high probabilities of engaging high time in SB. Male adolescents in the unhealthy class had low probabilities of being active and high probability of consuming a low-quality diet. In contrast, girls' healthiest profile presented lower probabilities of being active compared to boys' healthiest profiles. No association was found between weight status and classes. CONCLUSION: All classes had at least one unhealthy behavior, for both the whole sample, and for girls and boys. Girls' profiles were unhealthier compared to boys' profiles. Hence, it is recommended that intervention strategies to change behaviors need to be distinct according to sex, targeting more than one obesogenic behavior at the same time.

Clustering of Physical Activity, Diet and Sedentary Behavior among Youth from Low-, Middle-, and High-Income Countries: A Scoping Review.

BACKGROUND: The interaction between physical activity (PA), diet, and sedentary behavior (SB) plays an important role on health-related outcomes. This scoping review (Prospero CRD42018094826) aims to identify and appraise clusters of PA, diet, and SB among youth (0-19 years) according to country income. METHODS: Five databases were searched. Fifty-seven articles met the inclusion criteria. RESULTS: Fifty-five cluster types were identified, with greater variety in high-income than lower income countries. The most prevalent profiles were "High SB and consumption of sugar, salt, and beverages (SSB)" (n = 17) and "High PA" (n = 13-5), both of which presented in all income countries. The healthiest profile, "High PA and fruit and vegetables (F&V); Low SB and SSB" (n = 12), was present in upper-middle and high-income countries, while the unhealthiest "Low PA and F&V; High SB and SSB" (n = 6) was present only in high-income countries. CONCLUSIONS: High SB and unhealthy diet (SSB) were more prevalent in clusters, mainly in high-income countries. The results support the need for multi-component actions targeting more than one behavior at the same time.

Adequate sleep duration among children and adolescents: a review of the Brazil's Report Card / Duração do sono adequada entre crianças e adolescentes: revisão para o Report Card Brazil

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.

resumo - Objetivou-se resumir os estudos existentes que examinaram a prevalência de duração adequada do sono ou atendimento às recomendações de sono entre crianças e adolescentes brasileiros. Uma revisão sistemática foi realizada em oito bases de dados. Os critérios de inclusão foram pesquisas originais, amostras incluindo crianças e adolescentes brasileiros (de 0 a 18 anos), estudos que relataram variáveis ​​relacionadas à duração do sono usando medidas objetivas ou subjetivas, pesquisas baseadas na escola ou na população com amostragem aleatória e transversal ou estudos de coorte. Dos 54 artigos incluídos, apenas 27 utilizaram dados de estudos diferentes. A maioria dos estudos foi realizada na região sul (n = 17), com apenas dois estudos tendo uma amostra representativa nacionalmente. Dois estudos incluíram crianças menores de cinco anos, e a faixa etária mais investigada foi de adolescentes (> 10 anos). A maioria dos estudos utilizou um questionário autorreferido e mostrou variabilidade no ponto de corte aplicado para a duração adequada do sono com a maioria relatada sendo ≥8 horas. A proporção de adolescentes que cumpriram as recomendações ou tiveram uma duração de sono adequada variou de 15% a 89%. Entre as crianças, a prevalência variou de 17% a 95%. A menor variabilidade foi observada entre as crianças, variando de 93% a 95%. Nenhuma diferença de gênero consistente foi observada entre os grupos. Observa-se que, pela ampla variabilidade de resultados e pela carência de dados com representatividade nacional, a prevalência de sono suficiente em jovens com menos de 18 anos permanece indefinida no Brasil.

Smoking among industrial workers in Brazil: association with sociodemographic factors, alcohol consumption, and stress levels.

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.

Clustering of obesogenic behaviors and association with body image among Brazilian adolescents in the national school-based health survey (PeNSE 2015).

This study aimed to examine the association between clusters of obesogenic behaviors and body image indicators among a population-based sample of Brazilian adolescents. Data from a cross-sectional country representative survey of 9th grade students (N = 102,301) were analyzed. Physical activity (PA), sedentary behavior (SB) and body image indicators (i.e. satisfaction, perception, value, and weight control attitudes and behaviors) were self-reported. Three clusters were previously validated with two-steps cluster analysis: "Health-promoting SB and diet", "Health-promoting PA and diet", and "Health-risk". Multinomial and binary logistic regression were used to associate clusters with body image indicators. Adolescents in the healthier clusters were more likely to be satisfied/very satisfied with body image and perceive themselves as having normal weight than those in the "Health-risk" cluster. Boys in both health-promoting clusters were more likely to consider body image as being important/very important and perceive themselves to be thin/very thin. Adolescents in the "Health-promoting PA and diet" cluster were more likely to be trying to lose or gain weight than those in the "Health-risk" cluster. Girls in the "Health-promoting SB and diet" cluster had lower odds of adopting unhealthy weight control behaviors than those in the "Health-risk" cluster. The effect of obesogenic behaviors on distinct aspects of body image was confirmed and found to vary according to different synergies between adolescents' health-related behavior. These findings provide important insights on the understanding of behavioral profiles which can be targeted to prevent unhealthy weight control behaviors and weight related disorders, especially among girls.

Clustering of diet, physical activity and sedentary behavior among Brazilian adolescents in the national school - based health survey (PeNSE 2015).

BACKGROUND: There is a lack of evidence regarding clusters of health-related behaviors among adolescents from low, lower-middle, and upper-middle income countries. This study aimed to identify clustering patterns of health-related behaviors (diet, physical activity [PA] and sedentary behavior [SB]) and association with sociodemographic variables among a population-based sample of Brazilian adolescents. METHODS: Cross-sectional data from the 2015 National School-Based Health Survey (PeNSE). A total of 102,072 (females: 51.7%) students in ninth-grade (age: 14.3 ± 1.1 years-old) enrolled in public and private schools were investigated in this study. Healthy and unhealthy diet, PA and SB were measured using a validated questionnaire. Two-step cluster analysis was conducted to identify lifestyle patterns. The methodology for complex analysis and weighting was used to inferential statistical procedures. Multinomial logistic regression assessed associations between sociodemographic factors and the clusters. RESULTS: Three reliable and meaningful clusters were identified and labelled as follows: (1) health-promoting SB and diet (32.6%); (2) health-promoting PA and diet (44.9%), and (3) health-risk (22.5%). Compared to boys, girls were less likely to be in clusters 1 (OR = 0.85; 95% CI = 0.78-0.93, p < 0.001) and 2 (OR = 0.43; 95% CI = 0.40-0.46, p < 0.001) than the health-risk cluster. Higher socioeconomic status was positively associated with health-promoting PA and diet, and negatively related to health-promoting SB and diet. Older adolescents were more likely to be in cluster 1 than in cluster 3, compared to younger adolescents. CONCLUSION: Approximately one-quarter of the population (health-risk cluster) reported engaging in multiple risk behaviors. Interventions may need to be tailored to specific adolescent groups, especially considering sociodemographic differences.

Behavioral and sociodemographic correlates of the body mass index in Brazilian workers / Correlatos comportamentais e sociodemográficos do índice de massa corporal em trabalhadores brasileiros

An unhealthy body composition has been linked with chronic diseases and premature deaths that could be prevented. It is desirable to understand how modifiable behaviors are linked to the body composition of industrial workers, and identify risk groups among the population to plan inter-ventions and policies. The aim of the study was to identify the sociodemographic, physical activity, sedentary behavior, and nutritional correlates of the body mass index (BMI) of Brazilian industrial workers. Data were used from the "Lifestyle and Leisure Habits of Industrial Workers" study (n = 45,508), conducted between 2006 and 2008, in 24 of the 27 Brazilian states. Gender, physical activ-ity practice, television viewing, consumption of sweetened drinks, weight, and height were reported by the participants, and BMI was calculated. Linear regression analysis was conducted to identify the factors associated with BMI. Women had a lower BMI when compared to men (-1.63 kg/m2, CI95%: -1.71; -1.56). Age and television viewing were positively associated with BMI and physically inactive adults had a BMI of 0.22 kg/m2 (CI95%: 0.15; 0.29) greater than those who were active dur-ing leisure time. There was no association between BMI and sweetened drink consumption. Usually, BMI is higher among men, older individuals, those who watch more hours of TV daily, and those who do not practice physical activity during leisure time. When possible, it is suggested to promote the practice the practice of physical activity during leisure time without directing actions to comply with the recommendation of 150 minutes per week with the understanding that some activity is better than none, as well as stimulate the reduction of TV viewing time among workers

A composição corporal não saudável tem sido associada a doenças crônicas e morte prematura que podem, em parte, serem prevenidas. Dessa forma, destaca-se a importância de compreender como comportamentos modi-ficáveis estão relacionados à composição corporal de trabalhadores da indústria e identificar quais são os grupos de risco. O objetivo do estudo foi identificar a relação entre fatores sociodemográficos, e comportamentais (ati-vidade física, comportamento sedentário e consumo de refrigerante) com o índice de massa corporal (IMC) de trabalhadores brasileiros da indústria. Os dados são do projeto "Estilo de vida e hábitos de trabalho da indús-tria" (n = 45.508), realizado entre 2006 e 2008, em 24 estados brasileiros. Sexo, prática de atividade física, visualização de televisão, consumo de refrigerante, peso e a altura foram relatados pelos participantes. Análise de regressão linear múltipla foi aplicada para identificar fatores associados ao IMC. As mulheres apresentaram menor IMC quando comparado aos homens (-1,63 kg/m2, IC95%: -1,71; -1,56). A idade e tempo de televisão apresentaram associação positiva com o IMC e os adultos fisicamente inativos apresentaram IMC de 0,22 kg/m2 (IC95%: 0,15; 0,29) maior que aqueles ativos durante o tempo de lazer. Não houve associação entre o IMC e o consumo de refrigerante. O IMC tende a ser maior entre os homens, indivíduos mais velhos, aqueles que não praticam AF durante o tempo de lazer e despendem maior tempo assistindo TV diariamente. Portanto, sugerimos a promoção da atividade física sem direcionamento de ações para cumprimento das recomendações de 150 minutos/semana, mas para a compreensão de que fazer alguma coisa é melhor do que nada. Ademais, sugerímos políticas para a redução do tempo de visualização de TV entre os trabalhadores

Community and environment for physical activity among young people: a systematic review of the Report Card Brazil 2018 / Ambiente comunitário para atividade física de jovens: uma revisão sistemática do Report Card Brasil 2018

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 self-reported studies, impairing data comparability. To date, no studies have been identified that provide information about the prevalence of combined environmental measures (perceived and objective).

Resumo Objetivou-se identificar evidências das prevalências de indicadores do ambiente comunitário relacionado a atividade física (AF) de jovens brasileiros. A revisão sistemática utilizou-se de oito bases de dados (PubMed, Scopus, Web of Science, LILACS, SPORTDiscus, BIREME, Scielo, and Google Scholar), com descritores em Português e Inglês. As variáveis de ambiente e comunidade incluem acesso, presença, proximidade, qualidade, segurança e poluição de/em espaços, estruturas, programas disponíveis para AF. Foram extraídos os dados de prevalência de jovens (maiores de 18 anos), que podem ser medidos subjetivamente e/ou objetivamente. No total, 23 documentos foram incluídos (n=2; relatórios nacionais), sendo 15 estudos diferentes. Houve mais estudos na região Sul (n=8), seguido do Nordeste (n=3) e Sudeste (n=3). O uso de instrumento auto relatado foi mais utilizado (n=15). Os estudos reportaram prevalências de percepção (positiva e/ou barreira) para acesso a estruturas, programas e/ou parques (n=13); presença de calçadas e ciclovias (n=4); proximidade com a residência (n=5); qualidade (n=5); segurança para crimes e trânsito (n=14) e poluição (n=6); quantidade de espaços e/ou estruturas no entorno da residência (n=1); e observação de adolescentes utilizando espaços públicos para AF (n=3). As taxas de prevalência apresentaram alta variabilidade de acordo com os indicadores do ambiente. Estudos na região Norte e Centro-oeste do país são inexistentes. As medidas de ambiente são distintas nos estudos com auto relato, o que dificulta a comparabilidade dos dados. Até o momento, não foi identificado estudos que forneçam informações sobre prevalências de medidas do ambiente utilizadas de maneira combinada (percebida e objetiva).

Physical aggression among adolescents from Santa Catarina: association with sociodemographic factors and physical activity / Envolvimento em brigas entre adolescentes de Santa Catarina: associação com fatores sociodemográficos e atividade física

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 (ORBoys: 0.66; ORGirls: 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.

Resumo Os objetivos do presente estudo foram testar possíveis diferenças entre os sexos quanto ao envolvimento em brigas nos últimos 12 meses e analisar a associação desse comportamento com fatores sociodemográficos e a participação em atividade física em rapazes e moças. Foram avaliados 6529 estudantes (15 a 19 anos) do ensino médio da rede pública estadual do estado de Santa Catarina. Dados sociodemográficos, o envolvimento em brigas e os tipos de atividades físicas foram investigados por meio de questionário previamente testado. Utilizou-se de análises de regressão logística binária bruta e ajustada. Os rapazes (36,9%) relataram maior envolvimento em brigas em relação às moças (26,0%, p<0,05). Rapazes que residiam em área urbana (OR:1,45) e não moravam com a família (OR: 2,22), assim como moças que estudavam no período noturno (OR: 1,26) apresentaram maiores chances de envolverem-se em brigas. Adolescentes de 17 a 19 anos possuíam chances reduzidas de envolverem-se em brigas (ORRapazes:0,66; ORMoças:0,80) comparados aos de 15 e 16 anos. A prática de atividades coletivas nos rapazes (OR: 1,56) e a prática combinada de atividades coletivas e individuais em rapazes (OR: 1,91) e moças (OR: 1,36) foram associadas ao envolvimento em brigas. Conclui-se que rapazes foram mais propensos a se envolverem em brigas, principalmente os mais novos, aqueles que não moravam com a família e que residiam em área urbana. Em ambos os sexos, o envolvimento em brigas foi maior entre os praticantes de atividades físicas coletivas.
