= the term itself is not neutral =  

 It is true that the article does not explain the use of the model in modern medicine. It should be noted, however, that there is no 'neutral' definition of health, the biomedical model of health is itself not neutral. The use of the model in public health (aside from the use within medicine testing) is inherently ideological (not a 'stain').  
 The definition should have two parts 1) the use of the term within medical practice, and 2) the use of the term in public health.
