Physical activity and sedentary behaviors associated factors in adolescents
Daniel Giordani Vasques,Adair da Silva Lopes
Revista Brasileira de Cineantropometria e Desempenho Humano , 2009,
Abstract: The purpose of this study was to analyze factors associated with physical activity and sedentary behaviors in adolescents. The sample consisted of 1675 students (784 boys and 891 girls) ranging in age from 11-17 years from Caxias do Sul, RS. A questionnaire was applied to identify physical activity level (PAL, 3-day recall) andweekly hours of sedentary behavior. Low PAL was defined as energy expenditure less than 37 kcal/kg per day, and elevated sedentary behavior (ESB) was defined as more than 14 h/week watching TV, playing video games or using a computer. Chi-square testresults indicated a higher prevalence of low PAL among girls (66.8%>43.2%, p<0.001), whereas the prevalence of ESB was higher among boys (89.6%>84.0%, p=0.001). Using a Poisson hierarchical regression model, low PAL was associated with up to 4 persons living at home (PR=1.21, 95%CI: 1.00-1.46) and low maternal PAL (PR=1.23, 95%CI:1.00-1.53) among boys, and with age 15-17 years (PR=1.30, 95%CI: 1.18-1.44), up to 4 persons living at home (PR=1.17, 95%CI: 1.04-1.31), having a TV in the bedroom (PR=1.13, 95%CI: 1.02-1.25) and passive transport to school (PR=1.10, 95%CI: 1.00-1.22) among girls. In girls, ESB was associated with high parental educational level(PR=1.08, 95%CI: 1.01-1.16) and having a TV in the bedroom (PR=1.15, 95%CI: 1.08-1.22). The results suggest an association between socioeconomic measures and risk behaviors (low PAL and ESB). Knowledge about the factors associated with low PAL and ESB facilitates the implantation of more effective interventions in order to promote a more active lifestyle.

Revista Brasileira de Cineantropometria e Desempenho Humano , 2007,
Abstract: The objective of the present study was to analyze the body fat, physical activity, and dietary patterns of male adolescents in a mountainous region of Santa Catarina state, Brazil. The subjects were 1,024 adolescents, 10 to 17 years old, from public and private schools. The sample was selected by a three-stage cluster sampling method, where the laststage sampling units were entire classes. The prevalence of overweight and obesity was determined considering body fat level estimated using predictive equations. Physical activity and food intake were assessed using a questionnaire. Statistical analyses included: descriptive statistics, Chi-square test, and one-way ANOVA with Scheffé post hoc multiple comparisons. It was observed that 25.6% of the adolescents were overweight or obese and 29.4% were physically inactive. Regardingdietary patterns, subjects reported the following consumption levels of sugars and fats: soft drinks (36.9%), sweets (41.3%), and fries (29.1%). In general, there were no differences in activity patterns, diet, or body fatness between age groups (10-17years). Adolescents enrolled at private schools exhibited higher body fatness (p<.001), less physical activity (p<.05), poorer dietary habits (high consumption of fries, soft drinks, sweets, high fat foods, and low consumption of vegetables; p<.05) than adolescents at public schools. Approximately one in four adolescents in the mountainous region exhibited excess body fat and insufficient physical activity. Poor dietary habits were observed in one out of three adolescents. In general, adolescent students at private schools had more body fat, less activity, and poorer dietary habits than those attending public schools. RESUMO O objetivo do presente estudo foi analisar a gordura corporal, o nível de atividade física e hábitos alimentares de adolescentes do Município de Lages, Regi o Serrana do Estado de Santa Catarina, Brasil.

Revista Brasileira de Cineantropometria e Desempenho Humano , 2004,
Abstract: The study had the purpose of presenting a profile on physical growth and social-demographic characteristics of 11 to 17 year old students from Florianópolis, SC, Brazil. The sample consisted of 2384 students (1201 girls and 1183 boys). The study variables were social class and body mass and stature for physical growth. Statistical analyses included descriptives, Student’s t-test for independent samples and analysis of variance with two factors (age and sex), using level of significance at a=0,05. The results showed that (a) the students belonged to social classes C (33.3%) and B2 (25.5%) according to ANEP (National Association of Research Companies) categories; (b) there were statistical differences for body mass among 15 to 17 year old boys and girls and for stature from 11 to 14 years of age; (c) when stratifying by School system (public or private) and age, it was found that body mass and stature means among boys from the private system were greater for all ages, although significant differences were observed only at 12 and 16 years of age for stature and at 12, and from 14 to 17 years of age for body mass. Girls from the private system were taller than those from the public system and heavier at 16 years of age. It was concluded that boys at the end of adolescence had higher body mass and stature than girls. Both boys and girls from the private system showed a tendency for being taller and heavier than students from the public system.

Revista Brasileira de Cineantropometria e Desempenho Humano , 1999,
Abstract: The objective of this study was to analyze anthropometric and body composition variables of children aged 7 - 10 years old with distinct ethnic-cultural backgrounds, from the state of Santa Catarina, Brazil. Data were collected from 1,757 children (males = 858; females = 899) from 3 different ethnic-cultural groups (Portuguese = 439; German = 434; Italian = 443) and one Ad-mixture group (n = 441). The sample was intentionally selected according to towns’ and schools’ predominant ethnic-cultural backgrounds and then cluster sampled by classroom. Anthropometric (body mass, stature andbone widths) and body composition variables (% fat, fat mass, lean body mass, sum of skinfolds and adiposity index) were analyzed by group, age and Sex. Anthropometric and body composition data were processed using SPSSPC for descriptive statistics, one-way ANOVA and Tukey’s post hoc test (p < 0.05). The results obtained made it possible to draw the following conclusions: a) The values of anthropometric variables for males aged 7 or 10 in the Italian and German ethnic-cultural groups were shown to be greater than those for the Portuguese group and were similar to the Ad-mixture group. Few statistically signifi cant differences were observed between males aged 8 or 9. Females in the German and Italian groupsalso exhibited greater values than the Portuguese group, although for a smaller number of variables. b) Few of the body composition variables could be statistically differentiated between groups, but it was found that the Portuguese group had lower values for lean body mass than the German and Italian ethnic-cultural groups at some ages. The majority of children were within the adiposity index range classed as excellent. However, 10% of all children were found to be obese.. ABSTRACT Este estudo objetivou analisar variáveis antropométricas e da composi o corporal em crian as, de 7 a 10 anos de idade, de 3 diferentes grupos étnico-culturais e um grupo miscigenado do Estado de Santa Catarina, Brasil.

Abstract: RESUMO Physical activity has been linked with several health bene ts. Despite the evidence from population surveys, the measurement of physical activity has presented a challenge for researches in the area. The present study intends to show the main instruments for measuring physical activity, as well as their limitations and advantages. The choice of the most adequate instrument should observe criteria such as quality, simplicity or others. Currently, the lack of a “gold standard” instrument, suggests that a combination of methods would be the means of providing better data. The development of new instruments, improvement of current ones and the combination of methods are possible choices presented in this study for the use of better quality instruments. A atividade física tem sido relacionada a diversos benefícios para a saúde. Apesar de evidências levantadas em estudos populacionais, a mensura o da atividade física tem representado um desa o para pesquisadores da área. O presente estudo pretende apresentar os principais instrumentos de medida da atividade física, suas vantagens e limita es. A escolha do instrumento mais adequado deve atender a alguns critérios como a qualidade, a praticidade do instrumento entre outros. A falta de um instrumento considerado “padr o” sugere atualmente a utiliza o de uma combina o de métodos de maneira a fornecer dados mais con áveis e precisos. A constru o de novos instrumentos, o re namento dos instrumentos existentes e a combina o de métodos s o possibilidades consideradas para o uso de instrumentos de melhor qualidade.

Abstract: OBJETIVO: Estimar a prevalência e os padr es dos fatores de risco para doen as cr nicas n o transmissíveis segundo o nível socioecon mico 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 press o arterial elevada, assim como e baixa aptid o cardiorrespiratória compuseram as variáveis biológicas. Regress o logística multinomial foi realizada para identificar variáveis associadas à simultaneidade dos fatores de risco para doen as cr nicas n o transmissíveis. RESULTADOS: Dos adolescentes, 62 e 31% apresentaram baixa aptid o cardiorrespiratória e elevado consumo de gordura, respectivamente. Dois em cada dez adolescentes tinha dois ou mais comportamentos de risco, e um ter o deles tinham pelo menos dois fatores de risco biológicos para doen as cr nicas n o transmissíveis. No total, 62% dos adolescentes tinham pelo menos dois fatores de risco para doen as cr nicas n o transmissíveis, com maior frequência nos estudantes mais velhos. Na análise simultanea 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). CONCLUS ES: Seis em cada dez adolescentes tinham pelo menos dois fatores de risco, enquanto a propor o do agrupamento desses fatores aumentou com a idade. Portanto, quanto mais precoce forem as interven es, provavelmente menos adolescentes estar o acometidos por agravos à saúde em idades mais avan adas. OBJETIVO: Estimar la prevalencia y los estándares de los factores de riesgo para enfermedades crónicas no transmisibles, según el nivel socioeconómico y la edad de los adolescentes de Caxias do Sul, en Rio Grande do Sul, Brasil. MéTODOS: Estudio transversal de base escolar, involucrando a 1.675 estudiantes (53,2% del sexo femenino), con edades entre 11 y 17 a os, de escuelas públicas y privadas. El consumo de tabaco y alcohol, el alto consumo de grasa en la dieta y el bajo nivel de actividad física constituyeron las variables comportamentales. Circunferencia de la cintura y presión arterial elevada y baja aptitud cardiorrespiratoria compusieron las variables biológicas. Se realizó regresión logística multinominal para identificar variables asociadas a la simultaneidad de los factores de riesgo para enfermedades crónicas no transmisibles.
