OBJETIVO: Avaliar a validade concorrente e a equivalência operacional do questionário "Lista de Atividades Físicas" em crianças.MÉTODOS: O estudo complementa o processo de adaptação transcultural do Physical Activity Checklist Interview. Participaram 118 escolares de sete a dez anos matriculados do segundo ao quinto ano do ensino fundamental de São Paulo, SP, em 2009. Foram quantificados o tempo de engajamento em atividades físicas moderadas a vigorosas e em atividades sedentárias, assim como custos metabólicos total e ponderado. Adotou-se o acelerômetro como medida de atividade física. Foram quantificados a atividade física total (counts/min) e o tempo em atividade física moderada a vigorosa. A validade foi avaliada pelo coeficiente de correlação de Pearson e a equivalência operacional por meio dos dados referentes à duração e avaliação da entrevista.RESULTADOS: Os valores do coeficiente de correlação entre os resultados provenientes do questionário e do acelerômetro variaram de 0,34 a 0,40. O questionário "Lista de Atividades Físicas" superestimou o tempo em atividade física moderada a vigorosa quando comparado ao acelerômetro. A duração média da entrevista foi de 24 minutos (mínima = 13 min; máxima = 41 min; desvio-padrão = 5 min). O item da entrevista com pior resultado foi a habilidade do escolar em estimar tempo (ruim ou regular em 24,8% das entrevistas).CONCLUSÕES: Em relação à versão original, o questionário "Lista de Atividades Físicas" apresenta valores similares de indicadores de validade concorrente e de equivalência operacional, confirmando a adequação do processo de adaptação transcultural.

OBJECTIVE: To assess the validity and operational equivalence of the "Physical Activity Checklist" in children.METHODS: This study complements the cross-cultural adaptation of the Physical Activity Checklist Interview, conducted with 118 school children aged between seven and ten years old, enrolled from the second to the fifth grades of primary education in the city of Sao Paulo, SP, Southeastern Brazil, in 2009. The questionnaire enables the quantification of time spent in moderate and vigorous physical activities and sedentary activities and the total and weighted metabolic costs. The accelerometer was adopted as a criterion measure of physical activity. The variables total physical activity (counts/min) and time spent in moderate to vigorous physical activity were quantified. The concurrent validity was assessed by Pearson's correlation coefficient while the operational equivalence was assessed by data concerning the duration and evaluation of the interview.RESULTS: The values for the correlation coefficient between the results from the questionnaire and the accelerometer ranged from 0.34 to 0.40. It was found that LAF overestimates time spent doing moderate and vigorous physical activity when compared to the accelerometer. The average duration of the interviews was 24 minutes (minimum = 13 min, maximum = 41 min, sd = 5 min). The interview item showing the poorest result was the children's ability to estimate time (poor or fair in 24.8% of interviews).CONCLUSIONS: In relation to the original version, the questionnaire "Physical Activity Checklist" presents similar indices of concurrent validity and operational equivalence, confirming the appropriateness of the cross-cultural adaptation.

OBJETIVO: Avaliar a confiabilidade do questionário Lista de Atividades Físicas em crianças. MÉTODOS: O estudo é parte da adaptação transcultural do questionário, realizado com 83 escolares de sete a dez anos, matriculados do segundo ao quinto ano do ensino fundamental da cidade de São Paulo, SP, em 2008. O questionário foi respondido pela criança por meio de entrevista individual, apresenta lista com 21 atividades físicas moderadas a vigorosas realizadas no dia anterior, é dividido em períodos (antes, durante e após a escola) e possui seção de avaliação da entrevista. O questionário permite quantificar: tempo em atividades físicas e sedentárias; e custos metabólicos total e ponderado. A confiabilidade foi avaliada comparando-se duas entrevistas realizadas com intervalo médio de três horas. Para a seção C (avaliação da entrevista), compararam-se dados da primeira entrevista e de um avaliador externo. Utilizaram-se a proposta de Bland & Altman e os coeficientes de correlação intraclasse e de correlação de concordância de Lin na avaliação da confiabilidade. RESULTADOS: Os limites inferiores dos coeficientes de correlação intraclasse para os desfechos analisados variaram de 0,84 a 0,96. A precisão e concordância variaram, respectivamente, de 0,83 a 0,97 e de 0,99 a 1. A reta estimada a partir de pares de valores obtidos nas duas aplicações para atividade física indica elevada precisão dos dados. O item da entrevista com pior resultado foi a habilidade em estimar tempo (regular em 27,7% das entrevistas). Os itens da seção C apresentaram coeficientes de correlação intraclasse entre 0,60 e 0,70, exceto o nível de cooperação (0,46). CONCLUSÕES: A Lista de Atividades Físicas apresenta alta confiabilidade para aferir atividade física e sedentária do dia anterior em crianças.

OBJETIVO: Descrever a atividade de hematofagia de Aedes aegypti e Aedes albopictus em área submetida ao controle e à vigilância entomológica. MÉTODOS: O estudo foi realizado de abril de 1993 a setembro de 1994, na cidade de Cosmópolis, Estado de São Paulo. Utilizou-se isca humana para coleta dos exemplares. Calculou-se o número médio mensal de fêmeas capturadas por domicílio segundo as áreas central e periférica do município e os locais intra e peridomiciliar. Apresenta-se o índice pluviométrico mensal sem ajuste de modelo. RESULTADOS: Observou-se a presença de fêmeas das espécies em 83% (Ae. albopictus) e 61% (Ae. aegypti) do período estudado. Os meses de janeiro, fevereiro e março apresentaram maior atividade de fêmeas para as duas espécies, com maior presença de Ae. albopictus do que de Ae. aegypti. Os exemplares foram capturados na área central e periférica da cidade, nos períodos matutino, das 9:00 às 12:00 e crepuscular vespertino, das 16:00 às 19:00. Com utilização de modelo de regressão de Poisson, observou-se que fêmeas de Ae. albopictus foram mais capturadas no peridomicílio, independente se área central ou periférica. CONCLUSÕES: Foi detectada diferença no perfil de atividade da hematofagia somente para o Ae. albopictus, sendo de relevância o peridomicílio. OBJECTIVE: To describe the hematophagous activity of Ae. aegypti and Ae. albopictus in an area under control and surveillance. METHODS: The study was conducted during 18 months, from April, 1993 to October, 1994, in Cosmópolis, São Paulo state, Brazil. Human baits were used to collect mosquitoes. The number of females captured is presented monthly by area of the city and local in the household. The rainfall was measured and indices are presented without model adjustment. RESULTS: The presence of females of both species was observed in 83% (Ae albopictus) and 61% (Ae. aegypti) of the period studied. The months of January, February and March presented the highest rates of activity for females of both species, with Ae. albopictus being more frequently captured than Ae. aegypti. Both species were captured in central and peripheral areas of the city, during the day from 9 to 12 am and from 4 to 7 pm. By a Poisson regression, it was observed that Ae. albopictus females were more frequently captured in the peri-housed area, in an independent way considering the area of the city. CONCLUSIONS: It has been identified difference on the hematophagous activity only for Ae. albopictus, being of importance the outside area of the house.

Lower extremity amputation is an increasing problem among diabetic patients and an important public health problem. The study purpose was to identify factors associated with lower extremity amputation.A matched case-control study was carried out among diabetic patients. Cases were selected in public health programs of the city of São Paulo, Brazil. One hundred and seventeen cases of diabetics with lower extremity amputation were compared to 234 controls of diabetics without amputation, matched by sex, age, and duration of disease. Sociodemographic variables, life habits (smoking and alcohol drinking), clinical aspects, and health education in diabetes were included. Univariate analyses and conditional logistic regression method were applied to data.Data showed evidence of association for: smoking, last glucose testor = 200 mg/dl, presence of peripheral somatic neuropathy and vibratory perception (tuning fork 128 Hz), and peripheral vascular disease. Diabetes treatment and attending nursing appointments for diabetes education were important factors for preventing lower extremity amputation in diabetic patients.The knowledge of determinants and intervening factors for this condition will lead to cost reduction and better quality of care delivered in public health services.
