His thesis was that a large number of people at small risk for a given disease may give rise to more cases than the small number of those at high risk. Rose's population strategy was that there would be a large benefit to the population by treating the low risk people .Large benefit to the community may offer little to the each participating person and in some instances harm and bringing more benefit to an individual may have small impact on the population's health. This was labelled the Prevention Paradox. Interesting, this conception assumes that it makes logical sense to speak of the health of an aggregate which I argue is a category error. Is there a health of the community distinct from the health of its individual members?
Rose's imperative was to decrease the total disease burden of a population.What is important in this formulation is that the aggregate is more important that any of the individuals who make up the aggregate.Individual bees mater little , it is the health of the hive that must be promoted.
Next the idea of risk factor comes into play. This notion was brought into prominence and became an accepted item in the jargon of medicine by the authors of the Framingham study which was tasked to find the cause of coronary heart disease and concluded there is not one single cause but rather there are a number of factors, designated as risk factors,the possession of which by a person can be considered to increase his risk of developing coronary heart disease. The field was ripe for the "treatment" of risk factors and "preventative" medicine blossomed ( replacing the archaic " preventive ")
The slippery notion of the nature of risk was given little attention in medical journals ( with the notable exception of this article by Dr Goodman )- see here- as the risk factor revolution of medicine burst forth, first with coronary heart disease and then for as many diseases whose risk factors the epidemiologists ( and young general medicine department faculty members with recently minted MPH degrees) could generate with increasingly broad based and coarse grained data dredging .To name a few, osteoporosis,hypertension, diabetes,cancers, all have accumulated their own array of risk factors as have alcoholic abuse, depression and internet addiction.With greatly increased access to computer statistics programs and processing and p value hacking it seemed that almost everything is a risk factor for something. and making big deals over small differences ( relative risks less than 2) increased the risk that reading the daily news would makes the average reader think he was at a risk for something.
With Rose's population thesis and the epidemiologists' increasing supply of risk factors the opportunities for the drug companies burst forth.The idea that just about any disease can be described as a public health issue opening the door for "public health solutions" which typically involves governmental involvement if not governable coercion, at least in the form nudges consisting of grants and public education campaigns.
People were increasing treated for pre-diseases; pre-coronary heart disease, pre- hypertension,pre-diabetes, and even pre-bipolar treatment for moody,irritable ,grumpy kids .Cardiologist Tom Giles sarcastically talked about everyone possessing the risk factors for being "pre-dead".
Pre-patients ,after being informed of some risk factor for something,were advised to see their
