ABSTRACT
Objetivo: Determinar si el uso diario de escaleras se relaciona con valores de presión arterial media, en un grupo de habitantes de un conjunto residencial con edificios de 4 pisos. Materiales y métodos:Estudio descriptivo, transversal. Se tomó la presión arterial a 125 sujetos sanos (50,4% mujeres) residentes en los 4 pisos de cada uno de los 4 edificios de un conjunto residencial. Se compararon los valores de presión arterial media según el piso de residencia mediante ANOVA de un factor y prueba de Bonferroni, y se estratificó el análisis según edad, sexo, obesidad, fumar, beber alcohol con frecuencia y actividad física. Resultados: Se encontró relación significativa (p<0,05) entre el promedio de presión arterial media y el piso de residencia, siendo marcadas las diferencias especialmente entre el piso uno y el cuatro (p<0,05). Se encontró significancia estadística (p<0,05) al estratificar los valores de presión arterial media según sexo masculino, obesidad abdominal y fumar. Conclusión: En los adultos sanos, participantes en el estudio, hubo un efecto benéfico en el uso diario de escaleras con respecto a los valores de presión arterial media.Palabras clave: Actividad física, presión arterial media, escaleras, obesidad, fumar
Objective:To determine if the daily use of stairs is related to values of mean arterial pressure, in a group of inhabitants of a residential complex with buildings of 4 floors.Materials and methods:Descriptive, cross-sectional study. Blood pressure was taken to 125 healthy subjects (50.4% women) living in the 4 floors of each of the 4 buildings of a residential complex. The values of mean arterial pressure were compared according to the residence floor by means of one-way ANOVA and Bonferroni test, and the analysis was stratified according to age, sex, obesity, smoking, frequent alcohol drinking and physical activity.Results:A significant relationship was found (p <0.05) between the meanarterialpressure average and the residence floor, the differences being marked especially between floor one and four (p <0.05). Statistical significance was found (p <0.05) when stratifying mean arterialpressure values according to male sex, abdominal obesity and smoking.Conclusion: In healthy adults, participants in the study, there was a beneficial effect in the daily use of stairs with respect to the values of mean arterial pressure.

O objetivo do trabalho foi avaliar a utilização de microdietas experimentais na alimentação inicial de larvas de pacu, Piaractus mesopotamicus, através do crescimento e sobrevivência dos animais. As larvas foram alimentadas por 28 dias com as dietas: - náuplios de Artemia (A); JJ - animais em jejum; T3 - dieta comercial (DC:HatchFry Encapsulon); processamento por spray dried sem material encapsulante (SDs); spray dried com material encapsulante (SDc); processamento por geleificação iônica (GI). As melhores médias de desempenho e sobrevivência foram obtidas pelas larvas alimentadas com artêmia. Entre as dietas experimentais a dieta comercial foi a que obteve a melhor resposta. De maneira geral, os resultados demonstraram a necessidade de organismos vivos na alimentação inicial das larvas de pacu, mas também a possibilidade de se introduzir dietas microparticuladas.
The objective was to evaluate the use of micro diets in the experimental of pacu larvae Piaractus mesopotamicus through the growth and survival of animals. The larvae were fed for 28 days with diets: Artemia nauplii (Ar), in fasting animals (JJ); commercial diet (CD: HatchFry Encapsulon), processing by spray dried without encapsulating material (SDc); spray dried with encapsulating material (SDc), processing by ion (GI). The best average performance and survival were obtained by larvae food with Artemis. Among the experimental diets to diet was the commercial that got the best answer. In general, results showed the need of living organisms in the initial feeding of larvae of pacu, but also the possibility of introducing hatchery diets.
