RESUMEN

AIM: To examine whether changes in public open spaces (POS) were associated with leisure-time walking (LTW) between 2014 and 2021. METHODS: The sample comprised a prospective cohort of individuals living in São Paulo City, Brazil. The baseline sample was collected in 2014/2015 (4042 people aged 12 y or older) and the second wave in 2020/2021 (1431 people aged 18 y or older, 35.4% of total). Changes in POS scores in 500-m network buffers were based on household address, including positive or negative maintenance and increases or decreases in parks, public squares, and bike paths between 2015 and 2020. The International Physical Activity Questionnaire was used to evaluate LTW in the baseline and second wave. To examine the association of LTW with changes in POS, we used multilevel models in 4 levels: health administration areas, census tracts, individuals, and observations of individuals. The exposure was the POS tertiles, and the outcome was LTW. RESULTS: Changes in LTW prevalence were observed in both periods and according to POS tertiles distributions. When adjusted for time (baseline/second wave), gender, education, and age, the highest POS tertile was significantly associated with a high likelihood for LTW (odds ratio = 1.44; 95% confidence interval, 1.03-2.02). CONCLUSION: The results showed that people in São Paulo who lived within 500-m buffers with the highest access to POS were more likely to practice LTW between 2014/2015 and 2020/2021. These results have important implications for policies that were implemented in 2014, including the New Master Plan to contribute to São Paulo's good ranking among healthy cities.

RESUMEN

The purpose of this study was to estimate the association between environmental variables and leisure-time physical activity levels in an adult population of a medium-sized city in Brazil. This is a cross-sectional study with a sample of 965 adults (20-59 years). Individual, socioeconomic, demographic and behavioral data were obtained through a population-based survey. Environmental data were collected through direct observation and subsequently georeferenced. The outcome variable was leisure-time physical activity level, dichotomized as insufficiently active (<150 min/week) and active (≥150 min/week). Physical activity-related facilities were categorized as public or private, and food outlets as healthy, unhealthy or mixed. Monthly per capita income and crime rate by census tract were used to categorize the social environment. Statistical analysis was performed using binary logistic regression (generalized estimating equation models). A direct association was found between the availability of public (adjusted OR = 2.16; 95% CI = 1.44-3.25) and private (adjusted OR = 1.21; 95% CI = 1.02-1.44) physical activity facilities in the census tract and leisure-time physical activity. A greater availability of mixed food establishments was associated with higher leisure-time physical activity levels (adjusted OR = 1.10; 95% CI = 1.004-1.22). Environmental characteristics can contribute together to leisure-time physical activity and could be the focus of policies aimed at promoting physical activity in middle-income countries.

---

This research estimated how leisure-time physical activity relates to environmental aspects in an adult population of a medium-sized city in Brazil. Nine hundred sixty-five adults (20­59 years) participated in a survey to give individual, socioeconomic, demographic and behavioral information. Researchers also directly observed the environment to collect data and subsequently georeferenced it, to further apply regression models (statistical analysis). Being active during leisure, (i.e. practicing 150 min/week or more), was related to having more public (city squares and outdoor gyms, walking areas and university campus) and private physical activity facilities (clubs, courts, sports halls, soccer fields and gyms), as well as having greater availability of mixed food establishments (restaurants, bakeries, supermarkets and hypermarkets). Therefore, environmental characteristics can contribute together to leisure-time physical activity and could be the focus of policies aimed at promoting physical activity in middle-income countries.

RESUMEN

Leisure-time physical activity (LTPA) is associated with access and use of public open spaces. The President João Goulart Elevated Avenue, currently denominated Minhocão, is a facility for leisure activities that is open for people during the night and weekends. The aim of this study was to examine if the prevalence of LTPA among individuals living in the surroundings of Minhocão is different according to proximity to, and use of, the facility. We conducted a cross-sectional study with cluster sampling with people aged ≥18 years who lived in households up to 500 m, and between 501 m and 1500 m of Minhocão. The survey was conducted between December 2017 and March 2019 using an electronic questionnaire. We conducted a bivariate analysis and Poisson regression to examine possible differences in LTPA according to the proximity of residences and use of Minhocão. The analysis used post-stratification weights. A total of 12,030 telephone numbers of people were drawn (≤500 m = 6942; and >500 m to ≤1500 m = 5088). The final sample included 235 residents who returned the questionnaires. There was a higher prevalence of individuals engaging in at least 150 min per week of LTPA among users than non-users (Prevalence Ratio = 2.19, IC95% 1.66 to 2.90), independently of sex, age, education, the distance of houses to nearest accesses and number of barriers. The main five barriers related to the usage of the Minhocão were safety issues in and around the Minhocão, rainy weather, lack of vegetation, and lack of facilities. People who used the park had higher prevalence of all types of LTPA than non-users. The results can serve to inform government decision-making on the future of Minhocão.

RESUMEN

BACKGROUND: Many studies have investigated the association between the built environment and physical activity behavior in urban settings. However, most of the studies conducted in low- and middle-income countries were cross-sectional, which are limited to identify behavioral determinants. We propose a prospective cohort study to verify the relationship between built environment features and leisure-time and transport-related physical activity in adults from Sao Paulo city, Brazil. METHODS: Prospective multilevel cohort, denominated "ISA-Physical Activity and Environment". It will build on the Health Survey of Sao Paulo in 2015 ("Inquérito de Saúde de São Paulo (ISA)" in Portuguese). The Health Survey of Sao Paulo, originally designed as a cross-sectional survey, had a multi-stage sample, covering 150 census tracts distributed in five health administrative areas. Data collection was performed by face-to-face interviews until December 2015 and the sample comprised 4043 individuals aged 12 years or more. The ISA-Physical Activity and Environment study will reassess people who are aged 18 years or more in 2020, including telephone and household interviews. The primary outcome will be leisure-time and transport-related physical activity, assessed through the International Physical Activity Questionnaire long version. Exposure variables will be built environment features in the areas participants live and work in the follow-up. Data analysis will include multivariate multilevel linear and logistic models. We will also conduct cost-effectiveness analysis and develop agent-based models to help inform decision-makers. The study will be conducted by an interdisciplinary research team specialized in physical activity epidemiology, nutritional epidemiology, georeferencing applied to health, statistics, agent-based modeling, public health policy, and health economics. DISCUSSION: There are few longitudinal studies on the relationship between the built environment and physical activity behavior in low- and middle-income countries. We believe that the ISA-Physical Activity and Environment study will contribute with important results for the progress of the knowledge in this field and for the implementation of policies that promote leisure-time physical activity and active travel in Sao Paulo and similar cities across the world.

RESUMEN

OBJECTIVES: To assess associations, both individually and in combination, between leisure-time physical activity and sedentary behavior, and cardiometabolic health. METHODS: This cross-sectional study included 13,931 civil servants participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Leisure-time physical activity was analyzed using the leisure-time domain of the long-form International Physical Activity Questionnaire, while questions related to cumulative sitting time and leisure-based screen time on a weekday and on one day on the weekend were used to establish sedentary behavior. Data analysis was performed using multivariate logistic regression. RESULTS: Following adjustment for confounding variables, high levels of leisure-time physical activity and low levels of sedentary behavior were both associated with favorable cardiometabolic health markers in both genders. When these two factors were analyzed in conjunction, taking the combination of low levels of leisure-time physical activity and high levels of sedentary behavior as the reference, the inverse associations with cardiometabolic variables became even more significant. CONCLUSION: High levels of leisure-time physical activity and low levels of sedentary behavior were both inversely associated with the cardiometabolic variables analyzed; however, the two variables when evaluated in conjunction appear to produce more consistent associations, particularly when sedentary behavior is evaluated according to leisure-based screen time.

RESUMEN

OBJECTIVES: To estimate the prevalence of leisure-time physical inactivity (LTPI) and associated factors among healthcare workers. MATERIAL AND METHODS: The cross-sectional study carried out with 2684 healthcare workers from 4 municipalities from the northeast region, Brazil. The LTPI was assessed by dichotomous question. The association between LTPI and the various independent variables was examined through the multinomial logistic regression analysis (crude and adjusted). RESULTS: The prevalence of LTPI was 47.9% (95% confidence interval (CI): 46.01-48.80). The adjusted analysis (sociodemographic and occupational characteristics) showed that women and individuals with higher levels of education were more LTPI (p = 0.05). CONCLUSIONS: The prevalence of LTPI was high among the population investigated, especially among women and individuals with higher education. These results show the importance of developing actions to encourage adherence to physical activity during leisure time among workers, especially among the most vulnerable groups (people with higher education and women), given the benefits of this behavior to health.

RESUMEN

BACKGROUND: Physical activity level (PAL) is known to play an important role in reducing risk factors associated with sedentarism, in addition to improving the mental health and health-related quality of life (HRQL). OBJECTIVE: Investigate the relationship of PAL and their domains with HRQL, mood state (MS) and anxiety. Method: 140 Physical Education students (23.6 ± 3.7 years) were evaluated. The Baecke Habitual Physical Activity and Quality of Life (QOL-36) questionnaires, State-Trait Anxiety Inventories (STAI-S and STAI-T) and Profile of Mood States (POMS) scale were used to investigate PAL, HRQL and mental health indicators. Pearson's correlation coefficient examined the association between PAL and both mental health and HRQL parameters. RESULTS: There was a correlation between state anxiety and both the domain leisure-time physical activity (LTPA) (p = 0.013) and total PAL score (p = 0.010). In relation to MS, a negative correlation was found between LTPA and total mood disorder (TMD) (p = 0.004). However, there were positive correlations between the vigor subscale and both LTPA (p=0.001) and total PAL (p=0.019). With respect to HRQL, analysis of the relationship between LTPA and total PAL demonstrated positive coefficients with the physical component summary (PCS) (p=0.000; p = 0.005), mental component summary (MCS) (p = 0.000; p = 0.006) and total HRQL (p = 0.000; p = 0.003). CONCLUSION: The findings suggest that the rise in LTPA was related to an increase in HRQL and MS. However, PAL was positively related to anxiety.

RESUMEN

INTRODUCTION: Familial partial lipodystrophy (FPL) is a rare genetic disorder characterized by selective lack of subcutaneous fat, which is associated with insulin-resistant diabetes. The Dunnigan variety (FPLD2) is caused by several missense mutations in the lamin A/C (LMNA) gene, most of which are typically located in exon 8 at the codon position 482. OBJECTIVE: The aim of this study was to assess and compare the dietary intake, leisure-time physical activity (LTPA), and biochemical measurements (glucose, A1C, and plasma lipids) in women with FPLD2 and without (control group, CG) and to examine the associations between dietary intake and biochemical measurements (BM). METHODS: LTPA was measured with a questionnaire and metabolic equivalent (MET) hours per week (hours/week) were calculated. Dietary intake by the 3-day recall method and clinical laboratory parameters were collected. RESULTS: Characteristics of women with FPLD2: 35.8 ± 13.9 years, fat mass = 10 ± 2.3 kg and fat free mass = 41.4 ± 4.5 kg (p < 0.05). Women with FPLD2 showed a smaller intake of energy (kcal), lipids, and carbohydrates and a large intake of protein (p < 0.01) compared to CG. Comparing the 2 groups in terms of LTPA, 78% of women with FPLD2 performed insufficient physical activity. In addition, they had a higher levels of glucose, A1C, and triglycerides (TG) and lower levels of high-density lipoprotein (HDL). There was no correlation between dietary intake and biochemical measurements. CONCLUSIONS: Women with FPLD2 have a lower intake of energy (kcal), lipids, and carbohydrates and greater changes in biochemical measurements. Because this is a rare disease, future studies are needed with encouragement of the practice of physical activity and of healthy eating habits, preventing the onset of diseases.

RESUMEN

Physical inactivity causes 5.3 million deaths annually worldwide. We evaluated the impact on population leisure-time physical activity (LTPA) of scaling up an intervention in Brazil, Academia das Cidades program (AC-P). AC-P is a health promotion program classified as physical activity classes in community settings which started in the state of Pernambuco state in 2008. We surveyed households from 80 cities of Pernambuco state in 2011, 2012 and 2013, using monitoring data to classify city-level exposure to AC-P. We targeted 2370 individuals in 2011; 3824 individuals in 2012; and 3835 individuals in 2013. We measured participation in AC-P and whether respondents had seen an AC-P activity or heard about AC-P. We measured LTPA using the International Physical Activity Questionnaire. We estimated the odds of reaching recommended LTPA by levels of exposure to the three AC-P measures. For women, the odds of reaching recommended LTPA were 1.10 for those living in cities with AC-P activity for less than three years, and 1.46 for those living in cities with AC-P activity for more than three years compared to those living in cities that had not adopted AC-P. The odds of reaching recommended LTPA increased with AC-P participation and knowledge about AC-P. AC-P exposure is associated with increased population LTPA. Extending AC-P to all cities could potentially impact non-communicable diseases in Brazil.

RESUMEN

BACKGROUND: Considering the high socioeconomic inequalities prevailing in Brazil and lifestyle as a strong determinant of morbidity and premature mortality, our purpose was to evaluate the degree of socioeconomic disparities in the prevalence of health behaviors among Brazilian adult population using data from the 2013 Brazilian National Health Survey. METHOD: Based on a sample of 49,025 individuals aged 20 to 59 years, we estimated the prevalence of several health behaviors and a score of unhealthy behaviors according to gender, education, race/color and possession of private health insurance. The prevalence ratios adjusted by age and gender were estimated by means of multiple Poisson regression and the analyses took into account the sampling design. RESULTS: Significant social inequalities were identified in the Brazilian adults. Higher prevalence of current smoking, leisure-time physical inactivity, sedentary lifestyle, whole milk consumption and low ingestion of greens, vegetables, and fruits were observed among the less educated, in the non-white population, and among those without private health insurance. Higher prevalence of heavy episodic drinking was found in the non-white population, but no difference in the consumption of fatty meat was found according to skin color. Score of unhealthy behavior higher than 6 was more frequent in lower educational strata (PR = 3.74) in the non-white population (PR = 1.39) and among those without private health insurance (PR = 1.78). Compared to women, men had higher prevalence rates of smoking, hazardous alcohol consumption, and fatty meat consumption and lower consumption of greens, vegetables and fruits. CONCLUSION: The results of the study emphasize the importance of monitoring social inequalities in health as part of national health policies and the urgent need to prioritize actions to promote healthy behaviors, especially among the most socially vulnerable segments of society.

RESUMEN

OBJECTIVE: Thrifty genotypes may predispose to type 2 diabetes and body fat (%BF) excess through a differentiated relationship between physical activity and body fat. We explored this hypothesis in Asian Indians, a population thought to be thrifty. METHODS: Three hundred and nine Guadeloupian adolescents responded to the modifiable activity questionnaire. Their body fat was assessed by bioimpedancemetry. We first studied the relationship between %BF and leisure time physical activity (LTPA). We then explored the associations of ethnicity with this relationship in a subgroup of 93 Asian Indians matched with 93 controls for age, sex, and LTPA class. The alpha risk retained was .05. RESULTS: The analyses showed that Asian Indians had higher %BF even when matched with controls for age, sex and LTPA quartile, and the relationship between LTPA and %BF observed in controls was not evidenced in Asian Indians. CONCLUSIONS: The higher %BF in Asian Indians remained significant even when they were matched with controls for age, sex and LTPA quartile, and their LTPA was not associated ‒ or was at least less robustly associated ‒ with %BF. These findings are consistent with the hypothesis of thriftiness in Asian Indians, with the weaker relationship of high LTPA and low %BF a possible path to thriftiness.

RESUMEN

The main objective of the study was identify the prevalence and factors associated with leisure time physical activity (LTPA) in adult participants of the Longitudinal Study of Adult Health (ELSA-Brasil). The LTPA was measured using the International Physical Activity Questionnaire (IPAQ), long version. A hierarchical ecological model was built with the possible factors associated with LTPA distributed across blocks. We estimated crude and adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) using logistic regression. In men, being more educated, having a high family income, living in environments with conditions and opportunities for PA, being retired and being overweight were positively associated, while current smoking, obesity and abdominal obesity were associated negatively with the LTPA. Among women, being over 60years old, being more educated, having a high family income, living in an environment with conditions and opportunities for PA practice and being retired were positively associated, while being overweight, obese and having abdominal obesity were associated negatively with the LTPA. The proposed ecological model explains the LTPA through the social, physical and personal environment and highlights gender differences in physical activity.

RESUMEN

OBJECTIVE: To assess the effect of Leisure-time physical activity (LTPA) on cardiometabolic risk by nutritional status in Mexican children and adolescents. METHODS: This was a cross-sectional study conducted with 1,309 participants aged between 5 and 17 years. Nutritional status was classified according to the BMI Z-score by age and gender. A previously validated questionnaire was used to evaluate LTPA; a cardiometabolic risk score was calculated. Multiple linear regression analysis was performed to assess the effect of LTPA on cardiometabolic risk. RESULTS: After adjusting for risk factors, mild LTPA were positively associated with cardiometabolic risk score (ßMildvsIntenseLTPA: 0.68; 95% CI: 0.18 to 1.18; pfortrend = 0.007). This association became stronger when estimated for overweight (ß MildvsIntenseLTPA: 1.24; 95% CI: 0.24 to 2.24; pfortrend = 0.015) and obese participants (ß MildvsIntenseLTPA: 1.02; 95% CI: 0.07 to 1.97; pfortrend= 0.045) CONCLUSION: Mild LTPA was positively associated with cardiometabolic risk in overweight and obese children and adolescents. Given the emerging childhood obesity epidemic in Mexico, these results may be useful in the design of strategies and programs to increase physical activity levels in order to achieve better health. .

OBJETIVO: Avaliar o efeito da prática de AFL sobre o risco cardiometabólico em crianças e adolescentes mexicanos de acordo com sua situação nutricional. MÉTODOS: Estudo transversal feito com 1.309 participantes de cinco a 17 anos. A situação nutricional foi classificada de acordo com o escore z de IMC por idade e sexo. Um questionário validado anteriormente foi usado para avaliar a AFL; foi calculado um escore de risco cardiometabólico. A análise de regressão linear múltipla foi feita para avaliar o efeito de AFL sobre o risco cardiometabólico. RESULTADOS: Após o ajuste de acordo com os fatores de risco, a AFL leve foi positivamente associada ao escore de risco cardiometabólico (ßAFLLevexIntensa: 0,68; IC 95%: 0,18 a 1,18; p paratendência = 0,007). Essa associação foi mais intensa quando estimada para participantes acima do peso (ßAFLLevexIntensa: 1,24; IC 95%: 0,24 a 2,24; p paratendência = 0,015) e obesos (ßAFLLevexIntensa: 1,02; IC 95%: 0,07 a 1,97; p paratendência = 0,045). CONCLUSÃO: A AFL leve foi positivamente associada ao escore de risco cardiometabólico em crianças e adolescentes acima do peso e obesos. Considerando a epidemia de obesidade infantil emergente no México, esses resultados poderão ser úteis na elaboração de estratégias e programas para aumentar os níveis de atividade física a fim de obter uma saúde melhor. .

RESUMEN

BACKGROUND: Psychosocial job factors (PJF) have been implicated in the development of cardiovascular disease. The paucity of data from developing economies including Mexico hampers the development of worksite intervention efforts in those regions. METHODS: This cross-sectional study of 2,330 Mexican workers assessed PJF (job strain [JS], social support [SS], and job insecurity [JI]) and biological cardiovascular disease risk factors [CVDRF] by questionnaire and on-site physical examinations. Alternative formulations of the JS scales were developed based on factor analysis and literature review. Associations between both traditional and alternative job factor scales with CVDRF were examined in multiple regression models, adjusting for physical workload, and socio-demographic factors. RESULTS: Alternative formulations of the job demand and control scales resulted in substantial changes in effect sizes or statistical significance when compared with the original scales. JS and JI showed hypothesized associations with most CVDRF, but they were inversely associated with diastolic blood pressure and some adiposity measures. SS was mainly protective against CVDRF. CONCLUSION: Among Mexican workers, alternative PJF scales predicted health outcomes better than traditional scales, and psychosocial stressors were associated with most CVDRF.

RESUMEN

OBJETIVO: Analisar a prevalência e os fatores sociodemográficos associados aos diferentes domínios da atividade física em adultos de etnia negra. MÉTODOS: Estudo transversal com amostra de 2.305 adultos negros de 20 a 96 anos de idade, sendo 902 (39,1%) homens, residentes na cidade de Salvador, BA, Brasil. Foram analisadas as variáveis sociodemográficas sexo, idade, escolaridade, nível socioeconômico (NSE), estado civil, discriminação racial no trabalho/escola (DRTE), em ambientes públicos (DRAPU) e privados (DRAPR) e percepção de policiamento (PPB)/violência no bairro (PVB), além da atividade física total (AFT) e em diferentes domínios: tempo livre (AFTL), trabalho (AFTR), deslocamento (AFDL) e doméstico (AFDM). As associações foram analisadas por meio dos testes qui-quadrado, qui-quadrado de tendência e razão de prevalência (RP). Utilizou-se também regressão logística para estimar a razão de chances (RC) com intervalo de confiança de 95%. RESULTADOS: As proporções de indivíduos ativos foram 39,1% para AFT, 11,2% para AFTL, 9,6% para AFTR, 23,7% para AFDL e 33,7% para AFDM. A AFT associou-se positivamente com escolaridade e inversamente com sexo masculino, idade maior que 60 anos e com não PPB. A AFTL associou-se positivamente com sexo masculino, maior escolaridade e maior NSE. A AFTR associou-se inversamente à idade maior que 60 anos e positivamente com o sexo masculino, maior escolaridade e não PPB. A AFDL associou-se inversamente à idade maior que 60 anos e positivamente ao sexo masculino. A AFDM associou-se inversamente com o sexo masculino, idade maior que 60 anos e não PPB; e positivamente com maior escolaridade e NSE. CONCLUSÕES: Os fatores sociodemográficos, principalmente sexo, idade e escolaridade se mostraram associados aos diferentes domínios da atividade física em adultos de etnia negra.

OBJECTIVE: To analyze the prevalence and sociodemographic factors associated with different domains of physical activity among adults of black ethnicity. METHODS: Cross-sectional study with a sample of 2,305 black individuals from 20-96 years of age, 902 (39.1%) of which men living in the city of Salvador, Bahia, Brazil. Sociodemographic variables analyzed were: gender, age, schooling, socioeconomic status (SES), marital status, racial discrimination at work/school (RDWE), in public (RDPUP) and private (RDPRP) places and perception of police (PPN) /violence in the neighborhood (PVN), as well as total physical activity (TPA) in its different domains: leisure time (LTPA), work (WPA), commuting (CPA) and household activity (HPA). Associations were analyzed using chi-square tests, chi-square trend and prevalence ratio (PR). We also used logistic regression analysis to estimate the odds ratio (OR) with a 95%confidence interval. RESULTS: The proportions of active individuals were 39.1% for TPA, 11.2% for LTPA, 9.6% for WPA, 23.7% for CPA and 33.7% for HPA. TPA was positively associated with higher schooling and inversely associated with male gender, age over 60 years and with no PPN. LTPA was positively associated with male gender, higher schooling and higher SES. WPA was inversely associated with age over 60 years and positively associated with male gender, higher schooling and no PPN. CPA was inversely associated with age over 60 years and positively associated with male gender. HPA was inversely associated with male gender, age over 60 years and no PPN and positively associated with higher schooling and SES. CONCLUSION: Socio-demographic factors, particularly gender, age and schooling were associated with different domains of physical activity among adults of black ethnicity.

OBJETIVOS: Avaliar prevalência, atividades praticadas no tempo destinado ao lazer (AFL) e suas variáveis associadas, entre gêneros, em Duque de Caxias/Rio de Janeiro, Brasil. Material e métodos: Trata-se de um estudo transversal, de base populacional, composto por 1246 adultos. Durante as visitas domiciliares foram aplicados questionários avaliando a prática de AFL, fatores sociodemográficos e medidas antropométricas. RESULTADOS: A inatividade física foi elevada (70 por cento) (p-valor <0,001) sendo os homens mais ativos (43,3 por cento) que as mulheres (20 por cento) (p-valor < 0,0001). Homens praticaram significativamente mais AFL competitivas e do universo masculino. Tomar conta de crianças foi um fator que aumentou a chance dos homens se engajarem em AFL (OR=2,75, p-valor=0,034), enquanto que entre as mulheres, aquelas que dispendiam menos tempo em atividades domésticas (OR=0,99, p-valor=0,016), não fumavam (OR=2,63, p-valor=0,039) e que apresentavam maior acúmulo de gordura abdominal (OR=2,72, p-valor=0,023), tinham mais chance de praticarem AFL. CONCLUSÃO Conclui-se que homens repetiram modelo de escolhas de AFL consideradas masculinas. Fatores sócio-demográficos e medidas antropométricas se associaram com AFL de forma diferente entre gêneros.

OBJECTIVES: To evaluate the prevalence and associated variables in leisure-time physical activity (LTPA), by gender, in Duque de Caxias/Rio de Janeiro, Brazil. Methods: This is a population-based cross-sectional study with 1,246 adults. During home visits, questionnaires were applied on LTPA, socio-demographic factors and anthropometric examinations were performed. RESULTS: Physical inactivity was high (70 percent) (p-value <0001) and men were more active (43.3 percent) than women (20 percent) (p-value <0.0001). Men practiced significantly more competitive and male-associated LTPA. Taking care of children was a factor that increased the likelihood of men engaging in LTPA (OR = 2.75, p-value = 0.034), whereas among women, those who spent less time on domestic activities (OR = 0.99, p-value = 0.016), did not smoke (OR = 2.63, p-value = 0.039) and had greater accumulation of abdominal fat (OR = 2.72, p -value = 0.023), practiced LTPA. CONCLUSION: Men chose LTPAs considered masculine. Socio-demographic and anthropometric measures had different associations with LTPA between the genders.

RESUMEN

Introdução: Estimar o nível de atividade física é importante para o planejamento de intervenções, no entanto há poucos trabalhos que investigam o comportamento de professores neste aspecto. Objetivo: verificar, através de um estudo transversal, o nível de atividade física no lazer dos professores de educação física do ensino básico que atuam na zona urbana da cidade de Pelotas - RS. Método: estudo de caráter censitário, que utilizou o IPAQ (International Physical Activity Questionnarie) longo para verificação do nível de atividade física no lazer destes profissionais. Resultados: 188 professores responderam o questionário, 61,3% do sexo feminino, 55,4% concluíram pós-graduação e 56,4% foram classificados como ativos no lazer. O nível de atividade física no lazer, na análise ajustada, apresentou associação inversa com tabagismo (p=0,04) e direta com autopercepção de saúde (p=0,001). Conclusão: os professores apresentaram um nível de atividade física no lazer superior aos encontrados na população de Pelotas e não demonstraram os mesmos fatores de risco para inatividade física que a população em geral

Introduction: To estimate the level of physical activity is important for planning interventions, however there are few studies that investigate the teacherïs behavior in this aspect. Objective: the aim of this study was to verify, through a cross-sectional study, the level of physical activity of primary school and high school physical education teachers working in the urban area of the city of Pelotas, southern Brazil. Method: a census study, using the IPAQ long to check the level of physical activity in the leisure of these professionals. Results: 188 teachers answered the questionnaire, 61.3% females, 55.4% completed post graduation studies and 56.4% were classified as active in leisure-time. The level of physical activity during leisure time, in the adjusted analysis, presented inverse association with smoking (p=0.04) and direct with health?s self-perception (p=0.001). Conclusion: The teachers presented a level of leisure time physical activity considered higher than those found in the population of Pelotas and have not shown the same risk factors for physical inactivity when compared with the population in general

RESUMEN

INTRODUCTION: Leisure-Time Physical Activity (LTPA) is a health behavior that is considered relatively stable over the course of life; this life-long habit seems to be shaped during youth and early adulthood. LTPA is one of the few healthy behaviors more prevalent among men than among women. METHODS:Data from 3,199 participants of the Pro-Saude Study were analyzed - a cohort of employees of a university in Rio de Janeiro, collected with a self-reported multidimensional questionnaire. The association between LTPA in early adulthood and later was investigated using multinomial logistic regression, with estimated odds ratios (OR), considering three outcome categories: inactive, insufficiently active, and active. Past LTPA was grouped into three categories: never/rarely (reference category), sometimes and frequently/always. Estimates were adjusted for: age; participants' schooling, their father's and mother's schooling, and color/race. RESULTS:Analysis shows men who engaged in LTPA sometimes and almost always/always in early adulthood had an OR= 1.42 (95 percent CI: 0.70-2.89) and OR= 3.33 (95 percent CI: 1.82-6.10), respectively, of being physically active in later adulthood than those who did not engage in LTPA. Among women, the corresponding odds ratios were lower: OR = 1.19 (95 percent CI: 0.79-1.79) and OR =1.42 (95 percent CI: 1.00-2.04). CONCLUSION:LTPA during early adulthood is associated with physical activity later in adulthood, and this association is stronger in men than in women. Public policies that encourage LTPA among youth, with specific efforts directed at women, could increase the proportion of physically active adults.

INTRODUÇÃO: Atividade física é um comportamento de saúde relativamente estável, em geral determinado no início da vida adulta. Atividade física de lazer (AFL) é um dos poucos comportamentos benéficos à saúde mais prevalente entre homens que entre mulheres. MÉTODOS: Foram analisados dados de 3.199 participantes do Estudo Pró-Saúde - coorte de funcionários de universidade no Rio de Janeiro, coletados por meio de questionário multidimensional e autopreenchível. A associação entre AFL no início da vida adulta e posteriormente foi analisada com uso de regressão logística multinomial, com estimativas de razões de chance (odds ratio) e seus respectivos intervalos de 95 por cento de confiança considerando três categorias de desfecho: sedentários, insuficientemente ativos e ativos. AFL pregressa foi agrupada em 3 categorias: nunca/raramente (categoria de referência), às vezes, quase sempre/sempre. Estimativas foram ajustadas por idade, escolaridade, escolaridade dos pais e cor/raça. RESULTADOS:Homens que se engajavam em AFL às vezes e quase sempre/sempre no início da vida adulta tiveram, respectivamente, OR = 1,42 (IC 95 por cento: 0,70-2,89) e OR = 3,33 (IC 95 por cento: 1,82-6,10) de ser fisicamente ativos em idade posterior do que os sedentários. Entre as mulheres, os odds ratios foram menores: OR = 1,19 (IC 95 por cento: 0,79-1,79) e OR =1,42 (IC 95 por cento: 1,00-2,04). CONCLUSÃO:A prática de AFL durante o início da vida adulta apresentou associação com atividade física posterior, e essa associação foi mais expressiva em homens do que em mulheres. Políticas públicas que encorajem a AFL entre os jovens, com esforços específicos direcionados às mulheres, poderiam aumentar a proporção de adultos fisicamente ativos.

RESUMEN

As internações hospitalares representam uma importante fonte de gastos para o sistema de saúde. Neste estudo, o objetivo foi verificar a associação entre a inatividade física no tempo livre (IFTL) e IHTC (internações hospitalares por todas as causas), por problemas cardíacos (IHPC) e por diabetes (IHD) em adultos, na cidade de Salvador-Brasil. O estudo foi transversal, em amostra composta de 2290 adultos ≥ 20 anos de idade, sendo 1021 (44,6%) homens. Foram considerados como IFTL aqueles que informaram não participar de atividades físicas nos momentos de lazer, enquanto que internações hospitalares foram auto-referidas. Utilizou-se análise de regressão logística para estimar a odds ratio (OR) entre IFTL, IHTC, IHPC e IHD com intervalo de confiança de 95%. Após análise multivariada, encontrou-se associação entre IFTL, IHTC, IHPC e IHD em homens, enquanto que entre as mulheres observou-se associação apenas entre IFTL e IHD. Os resultados deste estudo são importantes para a saúde pública, à medida que podem ser utilizados para gerenciar programas de incentivo à prática de atividades físicas na perspectiva de prevenção das internações hospitalares e, conseqüentemente, redução de gastos para o sistema de saúde.

Hospital inpatient care is a significant source of expense for the healthcare system. In this study the objective was to verify the existence of an association between physical inactivity during free time (IFTL) and IHTC (hospital admissions for whatever cause), due to cardiac problems (IHPC) and diabetes (IHD) in adults in the city of Salvador in Brazil. This was a cross-sectional study of a sample of 2290 adults ≥ 20 years of age, 1021 (44.6%) being men. Subjects were defined as IFTL if they stated that they did not take part in physical activity during leisure time, while hospital admissions were self-reported. Logistic regression analysis was used to estimate the odds ratio (OR) between IFTL, IHTC, IHPC and IHD to a confidence interval of 95%. Multivariate analysis was then applied and detected an association between IFTL, IHTC, IHPC and IHD in men, while among the women there was only an association between IFTL and IHD. The results of this study are of importance for public health, to the extent that they could be used to facilitate the management of programs to encourage participation in physical activities with a view to preventing hospital admissions and consequently to reducing the costs to the health system.
