Although oral melatonin administration may enhance a nocturnal blood pressure fall, it remains unclear whether endogenous melatonin, which is present at considerably lower levels than pharmacological melatonin, is associated with the non-dipper pattern. The present cross-sectional study aimed to determine the association between urinary melatonin excretion, an index of endogenous melatonin, and the non-dipper pattern. We measured the following variables in 141 elderly hypertensives: overnight urinary melatonin excretion, ambulatory blood pressure and actigraphic physical activity.  [Actualizado: 12 de agosto 2013]

Although globalization can contribute to increased blood pressure by spreading unhealthy behaviors, it also provides powerful means to tackle hypertension. The dissemination of information about and advice on cardiovascular prevention and facilitated contact with health services are valuable resources. To investigate the effects of urbanization, geographical area, and air temperature on hypertension burden and kidney damage, a survey was performed in 2008 with a door-to-door approach among urban and rural adult dwellers of three geographic areas (capital, inland, coast) of Yemen.

The Joint Association of Physical Activity, Blood-Pressure Control, and Pharmacologic Treatment of Hypertension for All-Cause Mortality Risk

We conducted a study to determine the joint association of physical activity, pharmacologic treatment for hypertension, and the control of blood pressure (BP) on all-cause mortality risk.
Physical activity may be as or even more important than pharmacotherapy for reducing the risk of mortality in adults with hypertension. However, the risk of mortality remained higher for physically active adults with treated and controlled hypertension than did the risk of mortality for physically active normotensive populations. Prevention of hypertension is therefore imperative for reducing the all-cause risk of premature mortality in adults.  [Actualizado: 12 de agosto 2013].
