Stair Walk & Cell Phones: Evidence-Based Public Health
On March 28, Professor Sadik A. Khuder, Ph.D of the Departments of Medicine and Public Health & Preventive Medicine presented the third Grand Rounds in Public Health.
His excellent lecture initially delved into what evidence-based public health research actually is and that led into current research activities regarding obesity and the use of cell phones.
Here are some samples:
* There are 92 million Americans that fit the definition of “obese”;
* Using a 7-inch stair climber is cardio-protective;
* Putting up signs in front of elevators and escalators reminding the public that stairs really exist and that they can prolong one’s life didn’t change behavior, according to recent research.
* Installing distortion mirrors in front of elevators and escalators showing how one could look obese also didn’t change behavior for the most part.
*Over the past several years there have been contradictory studies and statements with regard to cell phones and the development of cancer. The most recent information indicates that while it may have carcinogenic properties on lab animals, there is insufficient evidence with regard to man.
* The prolonged use of a cell phone, however, has been shown to affect brain glucose metabolism but no one knows the clinical significance yet.
* Worried? Professor Khuder had some suggestions: 1) Alternate ears when you use your phone; 2) Use a wired ear piece; 3) Text, as long as you’re not driving.
Thank you, Professor Khuder.
