entre pessoas com 9 a 11 anos de educação formal. Entre as regiões, quanto menor o nível de escolaridade, maior a prevalência de hipertensão. Conclusão: a prevalência da HAS acima dos 65 anos não seguiu uma tendência linear, mas manteve-se elevada, com predomínio em idosos do sexo feminino e em idosos com baixa escolaridade, chamando a atenção para a necessidade de ações de prevenção dos fatores de risco e acompanhamento em longo prazo dos idosos hipertensos. AbstractObjective: to observe the evolution of the prevalence of hypertension in the Brazilian elderly population between 2006 and 2010. Methods: descriptive, ecological, quantitative study of the prevalence of hypertension among the Brazilian population aged 65 years or above, with data collected through telephone interviews from 2006 to 2010, obtained from the Information Technology Department of the Brazilian Public Health System (DATASUS), related to sex, region and education. Results: we found no significant difference in the prevalence of hypertension across Brazilian regions in the period analyzed. In women aged 65 years or above, the prevalence of hypertension was higher than in men in that same age group. With regard to education, we found that in people with 9-11 years of schooling the prevalence of hypertension in 2006 was significantly lower than in 2008 and 2009. Across Brazilian regions, the lower the education level the higher the prevalence of hypertension. Conclusion: The prevalence of hypertension in the population aged 65 years or above did not follow a linear trend but remained elevated, predominantly in elderly females and elderly people with low schooling, calling attention to the importance of preventing risk factors and to the long-term follow-up of people with hypertension. ResumenObjetivo: observar la evolución de la prevalencia de la hipertensión arterial (HTA) en los ancianos entre 2006 y 2010 en Brasil. Métodos: estudio descriptivo, ecológico, cuantitativo, de un periodo comprendido entre 2006 a 2010 con datos recogidos del Departamento de Informática del Sistema Único de Salud (DATASUS), relacionada con el sexo, la región y la educación en un grupo de edad de 65 años o más. Resultados: en el análisis entre las regiones de Brasil no hay diferencia significativa en los años analizados. En la comparación entre los sexos, la prevalencia de hipertensión en personas con 65 años o más fue mayor en mujeres que en hombres. En la escolaridad, fue encontrado que, con 9-11 años de estudio, la prevalencia en 2006 fue significativamente menor que en los años 2008 y 2009. Entre las regiones, cuanto menor sea el nivel de escolaridad, mayor es la prevalencia de la hipertensión. Conclusión: la prevalencia de la hipertensión en personas con más de 65 años no siguió una tendencia lineal, sino que se mantuvo elevada, sobre todo en mujeres de edad avanzada y en las personas mayores con baja escolaridad, llamando la atención sobre las acciones preventivas y de vigilancia de factores de riesgo en largo plazo en los hipertensos.

BackgroundUniversity professors are subjected to psychological stress that contributes to blood pressure (BP) reactivity and development of hypertension. The purpose of this study was to investigate the effects of exercise on BP in university professors during teaching and sleeping hours.MethodsTwelve normotensive professors (42.2 ± 10.8 years, 74.2 ± 11.2 kg, 172.8 ± 10.4 cm, 20.1% ± 6.7% body fat) randomly underwent control (CONT) and exercise (EX30) sessions before initiating their daily activities. EX30 consisted of 30 minutes of cycling at 80%–85% of heart rate reserve. Ambulatory BP was monitored for 24 hours following both sessions.ResultsBP increased in comparison with pre-session resting values during teaching after CONT (P < 0.05) but not after EX30. Systolic, diastolic, and mean arterial BP showed a more pronounced nocturnal dip following EX30 (approximately –14.7, –12.7, and –9.6 mmHg, respectively) when compared with CONT (approximately –6, –5 and –3 mmHg).ConclusionExercise induced a BP reduction in university professors, with the main effects being observed during subsequent teaching and sleeping hours.
