(June 13, 2017) Assistant Professor Dr. Divya Srinivasan’s study was featured in the Research section of the May issue of ISE Magazine (Page 51).   Dr. Srinivasan has been working with Dechristian Franca Barbieri from Brazil and Dr. Svend Erik Mathiassen from Sweden on a project on the usage of sit-stand tables and their effectiveness in reducing office workers’ prolonged sitting duration and potential health risks (e.g., obesity).

In their study, the sit-stand table was programmed with an alert system to remind office workers to change position at an interval of 10-minute standing and 50-minute sitting.  The system issued 12 to 14 alerts per day throughout the two-month testing period, and only 20 percent of those alerts were declined for any table change.

As the article describes, the table was in a standing position for about an hour and 15 minutes per work day.  The results indicate that the sit-stand table with alerts can reduce workers’ sitting time.  Some workers reported that changing their positions based on the table height positively contributed to their health and well-being without interrupting their regular work.  The researchers highlighted possible effectiveness of a semi-automated sit-stand table on increasing office workers’ non-sitting time and long-term health.
