Students and faculty from different programs of the Technological University of Pereira , have been engaged in a variety of actions in order to encourage the participation of the elderly in welfare centers in physical , artistic , cultural , and social activities to improve their quality of life .

The exclusion criteria were : Having some kind of restriction that affected the quality of information provided or that completely prevented its communication ( memory problems or dementia ) . Only six people were excluded . Results We did a ranges test to assess quality of life before and after the interventions and obtained more negative ranges ( 47 ) than positive ones ( 26 ) . Conclusions According to these results there was an increase in the quality of life in the elderly which cannot be attributed to a particular intervention , but to the contact with other people .
