Padrão de passos de mulheres hipertensas de um programa estratégia de saúde da família (ESF) / Standard steps of hypertension women in strategy family health program

O objetivo do estudo foi determinar o padrão de passos em mulheres hipertensas e correlacionar com as variáveis antropométricas. Foram avaliadas 54 mulheres hipertensas, com idade entre 32 a 80 anos, pertencentes ao Programa Estratégia de Saúde da Família da cidade de Taboão da Serra, região metropolitana de São Paulo. O padrão de passos foi avaliado por meio do pedômetro SW200. Os grupos foram divididos de acordo com a média de passos durante a semana em sedentária (<5.000 passos), irregularmente ativa (5.000 – 9.999 passos) e ativa (>10.000 passos). As variáveis antropométricas mensuradas foram Peso Corporal (PC), Estatura (E) e Circunferência da Cintura (CC). O IMC foi calculado utilizando as variáveis PC e E. Para análise estatística utilizou-se o Sperman rho e o teste de Wilcoxon. Utilizou-se o software SPSS 13. O nível de significância adotado foi p<0,05. De acordo com o número de passos, 25,9% foram consideradas sedentárias, 57,4% irregularmente ativa e 16,6% como ativas e a média de passos entre os grupos foi 3561 ± 1136; 7287 ± 1369 e 14082 ± 2209 respectivamente. O padrão de passos no fim de semana foi inferior aos dias da semana em que os resultados foram 8564 ± 4258 e 6298 ± 4128, respectivamente (p<0,05), uma redução de 26,4%. Houve uma correlação inversa entre a média de passos e IMC (r = -0,24) e a circunferência de cintura (r = -0,23). Concluiu-se que a maioria das avaliadas não alcançou a recomendação mínima de passos semanais. O número de passos foi associado a menores valores de IMC e circunferência da cintura. Houve redução de passos no fim de semana quando comparado aos da semana.

The purpose of this study was to determine the standard steps of hypertense women and correlation of the anthropometric variables. 54 hypertense women were evaluated, aged between 32 to 80 years old, participant of Taboão da Serra city Program of Family Health Strategy , in Sao Paulo metropolitan region. Standard steps level was evaluated by the use of SW200 pedometer. Sample was divided into groups according to the mean of steps per week: sedentary (<5.000 steps), irregularly active (5.000 – 9.999 steps) and active (>10.000 steps). The anthropometric variables as body weight, height and waist circumference followed CELAFISCS standard. BMI was calculated by using weight and height variables. Spearman rho and Wilcoxon test. SPSS 13 software was used. Significance level adopted was p<0.05. Results: The standard steps classification was based on the number of steps; percentage found was of 25.9% sedentary, 57.4% irregularly active and 16.6% active, and the mean of steps between the groups was 3561 ± 1136; 7287 ± 1369 e 14082 ± 2209, respectively. The number of steps profile on the weekend (Saturday and Sunday) was smaller than the on weekdays (Monday to Friday) the results were 6298 ± 4128 and 8564 ± 4258 respectively (p<0.05), with reduction of 26.4%. There was inverse association between number of steps mean and BMI (r = 0.24), as well as waist circumference (r = 0.23). Conclusion: Hypertense women showed unsatisfactory physical activity level measured by pedometer. Most of them did not reach the recommendation of weekly steps. The number of step was associated to lower BMI and waist circumference values. Physical activity level reduction on weekends was less than in the week.

Time trends in physical activity in the state of São Paulo, Brazil: 2002-2008.

PURPOSE: To document time trends in physical activity in the state of São Paulo, Brazil (2002-2008). In addition, we discuss the role of Agita São Paulo at explaining such trends. METHODS: Cross-sectional surveys were carried out in 2002, 2003, 2006, and 2008 in the state of São Paulo, Brazil, using comparable sampling approaches and similar sample sizes. In all surveys, physical activity was measured using the short version of the International Physical Activity Questionnaire. Separate weekly scores of walking and moderate- and vigorous-intensity physical activities were generated; cutoff points of 0 and 150 min·wk were used. Also, we created a total physical activity score by summing these three types of activity. We used logistic regression models for adjusting time trends for the different sociodemographic compositions of the samples. RESULTS: The prevalence of no physical activity decreased from 9.6% in 2002 to 2.7% in 2008, whereas the proportion of subjects below the 150-min threshold decreased from 43.7% in 2002 to 11.6% in 2008. These trends were mainly explained by increases in walking and moderate-intensity physical activity. Increases in physical activity were slightly greater among females than among males. Logistic regression models confirmed that these trends were not due to the different compositions of the samples. CONCLUSIONS: Physical activity levels are increasing in the state of São Paulo, Brazil. Considering that the few data available in Brazil using the same instrument indicate exactly the opposite trend and that Agita São Paulo primarily incentives the involvement in moderate-intensity physical activity and walking, it seems that at least part of the trends described here are explained by the Agita São Paulo program.

Physical activity in adults from two Brazilian areas: similarities and differences.

Lack of comparability has been a major limitation in studies on physical activity, due to the utilization of different methodological instruments and inconsistent cut-off points. This study aims to compare the levels of physical activity in adults from two Brazilian areas: (a) São Paulo, the richest State in the country; (b) Pelotas, a medium-sized southern Brazilian city. Both sites used cross-sectional population-based designs, with multiple-stage sampling strategies. Level of physical activity was assessed with the short version of the International Physical Activity Questionnaire. Prevalence of sedentary lifestyle was three times higher in Pelotas than in São Paulo. On the other hand, the proportion of very active subjects was significantly higher in Pelotas. The proportion of insufficiently active individuals (sedentary + irregularly active) was almost identical between the sites. Socioeconomic status was inversely related to level of physical activity in both sites. Among the insufficiently active subjects, those living in São Paulo are at least engaged in a limited amount of activity. On the other hand, among sufficiently active people, those living in Pelotas are more active.

Physical activity in adults from two Brazilian areas: similarities and differences

A incomparabilidade sempre foi uma limitacão entre os estudos sobre atividade física, em funcão da utilizacão de vários instrumentos e pontos de corte inconsistentes. Comparou-se o nível de atividade física de adultos do Estado de São Paulo e da cidade de Pelotas, Rio Grande do Sul, no Brasil. Ambos os centros usaram delineamento transversal de base populacional, com amostragem em múltiplos estágios. A prática de atividade física foi avaliada com a versão curta do Questionário Internacional de Atividade Física. A prevalência de sedentarismo foi três vezes maior em Pelotas do que em São Paulo. Já a proporcão de pessoas muito ativas foi significativamente maior em Pelotas. A prevalência de atividade física insuficiente (sedentários + irregularmente ativos) foi similar em ambos os centros. O nível sócio-econômico associou-se inversamente com o nível de atividade física nos dois centros. Entre as pessoas insuficientemente ativas, as de São Paulo estão ao menos praticando uma pequena quantidade de atividade física. Já entre os suficientemente ativos, as pessoas de Pelotas têm maior nível de atividade física.
