Does your mom have a subscription to AJPH? Cause you unfortunately need one to read the study itself here: http://www.ajph.org/cgi/reprint/AJPH.2008.157685v1

However, the abstract is here: http://www.ajph.org/cgi/content/abstract/AJPH.2008.157685v1

and the article I, erm, reprinted without permission (shhh!) is here: http://harvardscience.harvard.edu/medicine-health/articles/new-study-finds-45000-deaths-annually-linked-lack-health-coverage
