Well I got this out of my health book so I know its right...(Segall & Fries, Pursing Health and Wellness)
...just like 'ethnocentric' is used as a measuring device for one persons culture to judge another persons culture, to better understand them.
Health Sociologists use 'medico-centric' to describe the values and normalcies of biomedicine (biomedicine= looking at health as it relates to the physical aspects of disease or injury, not including features we can't see so readily like feelings, emotions, etc. ) to judge and understand health, illness, and the body.
Hope this helps :)
