“Brasil enfrenta epidemia de demência”, afirma pesquisadora

 

 

 

 

 

Um estudo realizado por pesquisadores da Faculdade de Medicina (FM) da USP indica que uma parcela significativa dos casos de demência diagnosticados no Brasil poderia ser evitada com o controle de doenças crônicas como hipertensão e obesidade. O que chamou a atenção dos pesquisadores foi que a proporção de demência do tipo vascular é maior no Brasil do que em outros países. O Jornal da USP no Ar conversou sobre esse assunto com a professora Cláudia Kimie Suemoto, da Disciplina de Geriatria e pesquisadora do Biobanco para Estudos em Envelhecimento da FMUSP. Ela também colabora com o Estudo Longitudinal da Saúde do Adulto (ELSA-Brasil).

Morning Exercise Lowers Blood Pressure

 

 

 

 

 

Wheeler’s group evaluated 67 sedentary participants with an average body mass index of 31.2 kg/m2and a mean age of 67.

Participants were assigned to each of the following in random order:

  • Exercise and breaks: sitting for 1 hour, moderate-intensity walking for 30 minutes, and then sitting interrupted every 30 minutes with 3 minutes of light-paced walking for 6.5 hours.
  • Uninterrupted sitting for 8 hours
  • Exercise and sitting: sitting for 1 hour, moderate walking for 30 minutes, and then uninterrupted sitting for 6.5 hours

The main limitation was lack of a group that only took breaks in sitting without more extensive exercise, Wheeler said.

“This was intentional, because we considered the evidence that an acute 30-minute bout of exercise impacts BP responses to be strong, and there are a number of studies that support the BP-lowering effect of active breaks compAdding a few minutes of walking throughout the day also helps, trial shows.

Weather Data Show Cold Temperatures Raise Risk of Heart Attacks, Report Suggests

 

 

 

 

 

The temperatures are dropping and a new report in JAMA Cardiology is warning that, with the colder weather, your risk of a heart attack increases. You’ve probably heard that before, but what’s new is this is the first time a study has followed both weather data and heart attack occurrences for so long — 16 years, The Washington Post said. Data showed that heart risk was highest at below-freezing temperatures.
