Validação do questionário Internacional de Atividade Física (IPAQ) através da acelerometria em idosas

Physical activity is one of the main components of a healthy lifestyle, responsible for many health benefits. Despite being considered important for both disease prevention and health promotion there is high prevalence of sedentary behavior in the elderly population. Questionnaires are practical and feasible instruments for assessing levels of physical activity. However, they may have limitations in older age ranges. Accelerometers, movement sensors that make physical activity data more objective, emerge as reliable measuring devices. Aim: Determine the validity of the International Physical Activity Questionnaire (IPAQ) adapted for elderly with accelerometry in elderly women. Methods: 57 elderly women, with mean age of 66.05 ± 5.98 years who took part in hypertension control and physical activity incentive programs were assessed in relation to objective and subjective measures of physical activity. The accelerometer was used for 07 consecutive days, 24 hours per day before the IPAQ was applied. Data were analyzed using measures of central tendency and dispersion to characterize the sample according to variables collected. To check the validity of the data we used the Spearman correlation test, considering a significance level of p <0.05. Results: With respect to the categories of physical activity obtained by IPAQ, 46.4% developed moderate physical activity, followed by a high (30.3%) and low level (23.2%). There was a negative correlation only between self-reported time spent sitting and time spent on light activities as measured by accelerometry (r = - 0.408; p = 0.003) and mean activity level (counts/min) with physical activity levels evaluated by IPAQ (r = 0.297; p = 0.036). Conclusion: The IPAQ used in elderly women shows moderate to low validity levels according to accelerometry measures. Assessment of sedentary activities exhibited acceptable levels compared to accelerometry; however, moderate (r = 0.096; p > 0.05) to vigorous (r = 0.098; p > 0.05) activities were not correlated, demonstrating the inability of IPAQ to evaluate this type of activity in elderly women

Birds of a central São Paulo woodlot: 1. Censuses 1982-2000

Foram listadas 263 aves próximo e dentro de uma mata semidecídua de 230 ha em meio a plantações de cana-de-açúcar, na região central do Estado de São Paulo, Brasil. Subtraindo-se 67 espécies de áreas abertas, 22 de riachos, 10 vagantes e 12 observadas mais tarde, cerca de 152 espécies de mata e de borda foram observadas entre 1982-86, semelhantemente às observadas em uma mata próxima a Campinas. Ambas as matas perderam espécies gradualmente. Algumas aves evitaram as margens duras dos canaviais, preferindo as margens macias arbustivas. Das espécies de área aberta, parece que 22 desapareceram até 1997, em razão das abundantes chuvas anteriores causadas por El Niño, ou pela raridade de habitats permanentemente abertos nos canaviais; 17 espécies novas eram principalmente noturnas que não haviam sido checadas anteriormente, ou visitantes ocasionais. A mata e as bordas perderam 37 espécies, ganhando 5 de regiões secas e 1 visitante de inverno. Vários migrantes do sul apareceram somente em anos chuvosos antes do recente efeito estufa; algumas aves residentes foram caçadas, e os beija-flores das copas talvez estivessem presentes ainda. As espécies de zonas secas, prones à movimentação ou metapopulacionais, movem os centros de distribuição, camuflando parcialmente a perda de diversidade da mata úmida.
