BACKGROUND: Many factors may negatively impact physical activity (PA), but studies lack evidence of individual predictors of perceived barriers to PA among adults in primary healthcare units. OBJECTIVE: To analyze associations between sociodemographic characteristics, health conditions, leisure-time physical activity (LTPA), PA counseling and perceived barriers to LTPA among adult patients in primary healthcare units of the National Health System in Brazil. DESIGN AND SETTING: Cross-sectional study on a representative sample of adults in primary healthcare units in São José dos Pinhais, Paraná, Brazil. METHODS: This study was conducted in 2019, among 779 adults (70% women). Barriers to LTPA, sociodemographic characteristics (sex, age, marital status, skin color, education and income), health conditions (body mass index, hypertension, diabetes, dyslipidemia, coronary disease and medications), LTPA level and PA counseling received were measured using validated, standardized procedures. The data were analyzed using chi-square and Mann-Whitney U tests. RESULTS: The most prevalent barriers were “feeling too tired” (53%) and “lack of time” (52%). PA counseling was inversely associated with “lack of time” (45% versus 57%; P < 0.001) but positively associated with “injury or disease” (38% versus 29%; P = 0.008). There was an inverse linear trend between the number of barriers and LTPA (walking and total) (P < 0.001). Most barriers differed in comparisons of sociodemographic characteristics, health conditions, LTPA and counseling (P < 0.05). CONCLUSIONS: The barriers vary according to the individual predictors. Counseling strategies need to be specific for each barrier and may be promising for promoting LTPA within primary healthcare.

Objective: To synthesize the evidence available in the literature on the relationship between the components of physical activity, physical fitness and academic achievement in adolescents. Methods: The review followed the methodological procedures described by PRISMA and was carried out in the Lilacs, Medline, SciELO, PubMed, Web of Science and Science Direct databases. Quantitative empirical studies published as of 2006 were included. The following descriptors and keywords were used: “Motor activity”, “Physical fitness”, “Physical activity”, “Educational status”, “Academic achievement”, “Academic performance”, and their equivalents in Portuguese and Spanish. Results: The most widely investigated variable was physical fitness (45.5%) followed by physical activity (40.9%), whereas only three studies (13.6%) investigated both. Conclusion: Physical activity and physical fitness are positively associated with the academic achievement of adolescents. In more than 80% of studies the association was considered strong. The physical fitness component most frequently associated with academic achievement was cardiorespiratory fitness. Level of evidence II; Systematic review.

Objective Summarize the effects of interventions designed to promote physical activity during elementary school recess in children between 5 and 10 years old. Effective school interventions for children can promote physical activity and healthy behaviors. Methods PubMed, Scopus, Bireme, SciELO, Web of Science, PsychINFO, Proquest, Physical Education Index, Sports Discus, and Eric databases were included in the data search. Original intervention articles on physical activity that used regression methods, published between 2000 and 2019 in English, Portuguese and Spanish were analyzed. Analyses were performed in 2019. Outcomes were organized according to the direction of the association by independent variables. Ten articles were considered eligible for data extraction and evaluation. Results Several strategies were used including playground markings, demarcation of physical activities zones, group activities, availability of sports equipment and facilities. Most of the studies were conducted in the United States. Recess periods ranged from 20–94 min per day and intervention time ranged from 6 weeks to 2 years. Recess duration and intervention effects were positively associated with physical activity. Gender (girls) and age (oldest) were negatively associated with physical activity during recess. Conclusions Interventions based on modifications of school environment such as playground markings demarcation of physical activities zones, group activities, availability of sports equipment and facilities are cheap and cost-effective for increasing physical activity in school recess.

The aim of this study was to analyze the association between perceived barriers for active commuting to school in the form of displacement of adolescents from Curitiba, Brazil. Interviews were conducted in six schools (three public and three private) with 741 adolescents aged 11-18 yrs. Perceived barriers for active commuting were assessed through a questionnaire with seventeen questions. Active commuting was defined as walking or bicycling to or form school at least one day per week. The associations were tested by Poisson regressions with 5% significance level. The prevalence of active commuting was of 42.9% (50.0% in boys and 37.2% in girls, p

FUNDAMENTO: Estilos de vida inadequados têm sido as principais causas de morte no mundo. O questionário "Estilo de vida fantástico" tem por finalidade auxiliar médicos que trabalham com prevenção, a fim de estes possam melhor conhecer e medir o estilo de vida dos seus pacientes. OBJETIVO: Traduzir e validar o questionário "Estilo de vida fantástico" para adultos jovens. MÉTODOS: O processo de tradução e adaptação envolveu quatro etapas: 1) tradução, 2) correção e adaptação semântica por especialistas da área (juízes), 3) avaliação da clareza do conteúdo e 4) avaliação por amostra da população-alvo. Análise estatística: para a consistência interna, utilizou-se o alfa de Cronbach; a consistência externa foi verificada pela correlação intraclasse (R); para a validade de construto, usou-se o índice Kappa. RESULTADOS: O alfa de Cronbach que avalia as correlações entre os itens e o total foi de 0,69, o que é considerado razoável para um instrumento desenhado para medir uma variável latente que somente pode ser estimada e não medida. Quando agrupados os itens em domínios, verificou-se que todos contribuem de maneira semelhante para a estabilidade do instrumento (α = 0,60). A reprodutibilidade avaliada pela correlação intraclasse foi alta (R = 0,92; p = 0,2). A validade de construto testada pela capacidade classificatória do instrumento em quatro e três categorias foi de 75% e 80,7%, com um índice Kappa de 0,58 e 0,7, respectivamente, o que evidencia uma ótima capacidade discriminatória. CONCLUSÃO: O questionário "Estilo de vida fantástico" possui uma consistência interna e externa adequada para a avaliação do estilo de vida de adultos jovens. Recomenda-se a utilização do questionário na atenção primária e em estudos epidemiológicos.BACKGROUND: Inappropriate lifestyles have been responsible for the leading causes of mortality. The purpose of the Fantastic Lifestyle Questionnaire is to help physicians involved in health prevention to identify and assess their patients' lifestyles. OBJECTIVE: To translate and validate the Fantastic Lifestyle Questionnaire for use with young adults. METHODS: The process of translation into Portuguese and validation consisted of four steps: 1) translation; 2) correction and semantic adaptation by professional experts (judges); 3) content validation; and 4) a final evaluation by the target population. The statistical analyses used were Cronbach's alpha to measure internal consistency reliability, intra-class correlation coefficient (R) for external consistency, and the Kappa index to test construct validity. RESULTS: Cronbach's alpha coefficient measured the correlation between items and the total was 0.69, which is considered reasonable for an instrument designed to evaluate a latent variable that can only be estimated and not measured. When the items were grouped into domains, it was possible to verify that they all contributed equally to the stability of the questionnaire (α=0.60). The external consistency evaluated by intra-class correlation was R=0.92 (p=0.2), which demonstrates a high degree of reproducibility; the construct validity of 4 and 3 categories was 75 and 80.7% with Kappa indices of 0.58 and 0.7, respectively, which show an excellent discriminatory classificatory capacity. CONCLUSION: The Fantastic Lifestyle Questionnaire has an adequate internal and external consistency for evaluating young adult lifestyles, and it can be recommended for primary care and epidemiological studies.

Este trabalho teve o objetivo de analisar a associação entre atividade física e autoeficácia em adolescentes. Realizou-se um estudo inquérito de base escolar com 1.698 adolescentes de Curitiba, Paraná, Brasil. A atividade física foi avaliada segundo frequência semanal (dias/semana) de prática de atividade física de intensidade moderada ou vigorosa. A autoeficácia foi analisada segundo a soma de uma escala composta por dez itens. A associação entre autoeficácia e atividade física foi testada pela regressão de Poisson (p < 0,05), estratificada por sexo. Entre os meninos, apenas elevada autoeficácia foi associada com todas as categorias de atividade física (p < 0,001), enquanto para as meninas níveis moderados e elevados de autoeficácia foram associados com todas as categorias de atividade física (p < 0,001). Conclui-se que a autoeficácia tem associação positiva com atividade física entre adolescentes, no entanto esta relação é mais consistente entre as meninas. Este é um aspecto importante para o delineamento de intervenções para a promoção de atividade física nesse grupo populacional. This study aimed to examine the association between physical activity and self-efficacy in adolescents. A school-based survey was conducted with 1,698 adolescents from Curitiba, Paraná State, Brazil. Physical activity was evaluated as weekly frequency (days per week) of moderate or vigorous physical activity. Self-efficacy was analyzed as the sum of a 10-item scale. The association between self-efficacy and physical activity was tested by Poisson regression (p < 0.05), stratified by gender. Among boys, only high self-efficacy was associated with all categories of physical activity (p < 0.001), while for girls moderate and high levels of self-efficacy were associated with all categories of physical activity (p < 0.001). In conclusion, self-efficacy showed a positive association with physical activity in adolescents, although the relationship was more consistent in girls. The finding is important for designing interventions to promote physical activity in this age group. El objetivo de este estudio fue analizar la asociación entre la actividad física y la autoeficacia en adolescentes. Se realizó una investigación de base escolar, mediante una encuesta a 1.698 estudiantes adolescentes de Curitiba, Paraná, Brasil. La actividad física se evaluó de acuerdo con la frecuencia semanal (días/semana) de práctica de actividad física con una intensidad moderada o elevada. La autoeficacia fue analizada conforme a la suma de puntos de una escala de 10 ítems. La asociación entre la autoeficacia y actividad física se probó mediante la regresión de Poisson (p < 0,05), estratificada por sexo. Para los adolescentes solamente una actividad física elevada presentó una asociación con todas las categorías de actividad física (p < 0,001), mientras que para las adolescentes unos niveles moderados y elevados de autoeficacia presentaron asociación con todas las categorías de actividad física (p < 0,001). Se concluye que la autoeficacia presenta una asociación positiva con la actividad física entre los adolescentes, sin embargo, esta relación es más consistente entre las adolescentes. Este es un aspecto importante para el diseño de intervenciones en salud, con el fin de promover la actividad física en este grupo de población.

The aim of this study was to verify the association between different types and sources of social support and physical activity among adolescents from Curitiba, Paraná State, Brazil. A school-based survey was conducted with a representative sample of adolescents from public schools (n = 1,469). Multiple regression models were used to test the association between weekly frequency and sources of social support from family and friends and weekly frequency of physical activity. Among boys, frequent company of family (PR: 2.88; 95%CI: 2.00-4.13) and friends (PR: 5.46; 95%CI: 2.33-12.78) and positive reinforcement from friends (PR: 1.81; 95%CI: 1.18-2.77) were positively associated with physical activity. Sporadic invitation by the family was negatively associated with physical activity (PR: 0.66; 95%CI: 0.46-1.14). For girls, frequent company of family (PR: 3.39; 95%CI: 1.49-7.69) and friends (PR: 4.06; 95%CI: 2.22-7.45) increased the likelihood of physical activity. Company of friends was the most important type of social support for physical activity among these adolescents.

The aim of this study was to verify the association between perceived distance to recreational facilities (parks, gyms, sports courts, and bike lanes) for physical activity and exercise among adolescents in Curitiba, Paraná State, Brazil. A cross-sectional study was conducted with a representative sample of 1,474 adolescents (14-18 years) enrolled in public schools. There was an inverse association between distance (31 minutes) to gyms and sports courts and physical activity among boys (PR = 0.78; 95%CI: 0.69-0.88 and PR = 0.79; 95%CI: 0.66-0.95, respectively). The number of facilities near home was positively associated with physical activity in boys (PR = 1.18; 95%CI: 1.04-1.34). Among girls, distance (31 minutes) to sports courts was inversely associated with strength training (PR = 0.93; 95%CI: 0.87-0.99). The findings suggest that distance from home and number of recreational facilities in the neighborhood may affect patterns of physical activity among adolescents and that the association differs between boys and girls.

This study aimed to examine the association between physical activity and self-efficacy in adolescents. A school-based survey was conducted with 1,698 adolescents from Curitiba, Paraná State, Brazil. Physical activity was evaluated as weekly frequency (days per week) of moderate or vigorous physical activity. Self-efficacy was analyzed as the sum of a 10-item scale. The association between self-efficacy and physical activity was tested by Poisson regression (p0.05), stratified by gender. Among boys, only high self-efficacy was associated with all categories of physical activity (p0.001), while for girls moderate and high levels of self-efficacy were associated with all categories of physical activity (p0.001). In conclusion, self-efficacy showed a positive association with physical activity in adolescents, although the relationship was more consistent in girls. The finding is important for designing interventions to promote physical activity in this age group.

OBJETIVO: Estimar a prevalência de atividade física e identificar fatores associados em adolescentes. MÉTODOS: Estudo transversal realizado com amostra representativa (n = 1.518, 59,2% do sexo feminino) de escolares de 14-18 anos de idade da rede pública de ensino de Curitiba, PR, em 2006. A prática de atividade física foi auto-referida, em número de dias por semana em que realiza atividade de intensidade moderada a vigorosa com duração > 60 minutos. A prática foi analisada em dois modelos distintos. No primeiro, a variável foi dicotomizada em "0 dia" e "> 1 dia"; no segundo, em "< 4 dias" e "> 5 dias". As variáveis independentes foram: demográfico-biológicas (sexo, idade, índice de massa corporal); socioeconômicas (escolaridade dos pais, número de carros); comportamentais (horas assistindo TV, horas em frente ao computador); e socioculturais (apoio social da família e dos amigos, e a percepção de barreiras para a prática de atividades) testadas em regressão de Poisson. RESULTADOS: No primeiro modelo de análise, a prevalência de atividade física foi de 58,2% (75,1% do sexo masculino e 46,5% do feminino; p < 0,001) e no segundo, de 14,5% (22,3% e 9,1%, respectivamente; p < 0,001). No primeiro modelo, as variáveis associadas à atividade física foram sexo masculino (RP = 1,63, IC95%: 1,48;1,78), apoio social da família (RP = 1,14, IC95%: 1,05;1,23), dos amigos (RP = 1,52, IC95%: 1,31;1,78) e elevada percepção de barreiras (RP = 0,54, IC95%: 0,46;0,62). No segundo modelo, apenas o sexo masculino (RP = 2,45, IC95%: 1,73;3,46) e a baixa percepção de barreiras (RP = 0,24, IC95%: 0,15;0,38) associaram-se à atividade física. CONCLUSÕES: Mais da metade dos adolescentes praticam atividade física em pelo menos um dia da semana, embora 14,5% atinjam as recomendações atuais. Níveis recomendados estão associados a menor número de fatores. Gênero e percepção de barreiras apresentam relação consistente com os níveis de atividade física. OBJECTIVE: To estimate the prevalence of physical activity in adolescents and to identify associated factors. METHODS: A cross-sectional study was conducted with a representative sample (n=1,518, 59.2% females) of students aged between 14 and 18 years, enrolled in the public school network of the city of Curitiba, Southern Brazil, in 2006. Physical activity practice was self-reported, according to the number of days per week when they perform moderate to vigorous physical activity lasting > 60 minutes. This practice was analyzed in two distinct models. In the first model, the variable was dichotomized into "0 day" and "> 1 day"; in the second, into "< 4 days" and "> 5 days". Independent variables were as follows: biological-demographic (sex, age, body mass index); socioeconomic (parents' level of education, number of cars); behavioral (number of hours spent watching television, number of hours spent using a computer); and sociocultural (social support from family and friends and the perception of barriers to the practice of activities), tested with Poisson regression. RESULTS: In the first model of analysis, the prevalence of physical activity was 58.2% (75.1% in males; 46.5% in females; p

O objetivo deste estudo foi analisar a prevalência de barreiras e sua associação com a prática de atividades físicas em adolescentes. O presente estudo, transversal, avaliou uma amostra representativa de escolares do ensino médio da rede pública da cidade de Curitiba-PR, Brasil. Um total de 1.609 escolares (59,7% do gênero feminino) entre 14 e 18 anos de idade reportou, por meio de um questionário, o nível de atividade física e as barreiras para a prática de atividades físicas. Para verificar a associação entre a prevalência de barreiras e a atividade física foi realizada uma análise de regressão logística para cada barreira investigada ajustando para variáveis de confusão (idade e nível socioeconômico). As análises foram realizadas separadamente para meninos e meninas. Apenas 22% dos meninos e 9% das meninas atingiram a atual recomendação para atividade física. Entre as 12 barreiras investigadas, apenas "não ter alguém para levar" não diferiu entre os gêneros. Para todas as outras, a percepção de barreiras foi maior entre as meninas (p < 0,05). "Não ter a companhia dos amigos" e "ter preguiça" foram as barreiras mais reportadas pelos meninos (30,4%) e meninas (51,8%), respectivamente; no entanto a barreira mais fortemente associada com maior prevalência de níveis insuficientes de atividade física foi "preferir fazer outras coisas" para meninos (OR = 5.02 (2,69 - 9,37); p < 0,05) e meninas (OR = 7.10 (3,71 - 13,60); p < 0,05). As barreiras percebidas para a prática de atividades físicas foram mais prevalentes entre as meninas e diferiram em grau de importância entre os gêneros. The aim of this study was to analyze the prevalence and association of barriers to physical activity among adolescents. This cross-sectional study evaluated a representative sample of public high school students in Curitiba-PR, Brazil. A total of 1,609 school adolescents (59.7% male) between 14 and 18 years of age answered a questionnaire on physical activity status and barriers to physical activity. Logistic regressions were conducted for each barrier investigated to verify the association between the prevalence of barriers and physical activity, adjusting for confounding variables (age and socioeconomic status). Analyses were done separately for boys and girls. Only 22% of boys and 9% of girls achieved the current physical activity recommendation. Among the 12 barriers investigated, only "there is nobody to take" did not differ between boys and girls. The perception of barriers was higher for girls than boys (p < 0.05) for all other barriers. "Lack of friends company" and "feel lazy" were the barriers most often reported by boys (30.4%) and girls (51.8%) respectively; however, the barrier most strongly associated with prevalence of physical inactivity was "prefer to do other things" for both boys (OR = 5.02 (2.69 - 9.37); p < 0.05) and girls (OR = 7.10 (3.71 - 13.60); p < 0.05). Perceived barriers for the practice of physical activity were more prevalent in girls and differed as to the extent of importance between genders.

In the first model, the variables associated with physical activity were: male sex (PR=1.63, 95% CI: 1.48;1.78), social support from family (PR=1.14, 95% CI: 1.05;1.23), social support from friends (PR=1.52, 95% CI: 1.31;1.78) and high perception of barriers (PR=0.54, 95% CI: 0.46;0.62). In the second model, only male sex (PR=2.45, 95% CI: 1.73;3.46) and high perception of barriers (PR=0.24, 95% CI: 0.15;0.38) were associated with physical activity.More than half of adolescents practice physical activity at least one day of the week, although 14.5% achieved the current recommendations. The recommended levels are associated with a lower number of factors. Gender and perception of barriers were consistently associated with physical activity levels.

Background Neighborhood safety is one of the environmental aspects that can influence physical activity. We analyzed the association between perceived neighborhood safety and physical inactivity (PI) in adults and examined effect modification according to sociodemographic variables. Methods A cross-sectional study was conducted with 1,261 adults (62% women), age 18–69 years from Curitiba, Brazil. Results The perception of unsafe neighborhood was higher among women, older participants, those classified in the high socioeconomic (SES) group, overweighed and also among those reporting to have PA equipments and children. The association between perception safety of walking during the day and walking for leisure (women PR = 1.12 CI95% = 1.02–1.22; men PR = 0.82 CI95% = 0.64–1.05; interaction term PR = 1.38 CI95% = 1.03–1.83) and safe perception was associated with PI, just in the highest SES group (PR = 1.09; CI95% = 1.00–1.19; p trend = 0.032) when compared with their counterparts (low SES PR = 0.99; CI95% = 0.90–1.04; p trend = 0.785; interaction term PR = 1.09; CI95% = 1.03–1.15; p trend = 0.007). Conclusion The perception of safety in the neighborhood was associated with PI in transport, but this association varies across of sociodemographic variables.
