Question

I am looking for an algorithm that shows the exact coefficients some variables that have on a hospital patient's chronological age versus their biological age.

I understand a lot of the variables that go into determining ones biological age (i.e. Blood pressure, diet, family history of disease, obesity etc.) but not the amount of impact that it has on the actual scoring of their age.

I have found many sites that will calculate it, however I need the actual variable coefficients and influence in order to produce a proper score for thousands of patient records.

Explanation / Answer

As the definition of biological age is very ambiguous, I propose that to generate an algorithm, you first need to create a quantifiable definition. I submit:

Biological age is a measure indicating what portion of one's calculated life expectancy is already expended, adjusted proportionately for the average life expectancy of their major demographic.

Wow, that's a mouthful! So, let's break it down.

Life expectancy is calculated :

Ascertain a person's major demographic (Geographic residence, Race, Gender and Generation).
Find the average life span of that demographic.
This is negligibly speculative as a living person's Generation has not yet fully perished
Statistical outliers, such as infant mortality, are generally excluded from this calculation
Adjust for known major factors that have accepted statistical impact.
eg:
Lifestyle
Current medical conditions
medical history

Average Life expectancy of subject's demographic was calculated in #2 above.

So, now let's throw in some sample numbers.

Statistical Facts: (totally made up)

Two subjects both Caucasian, french males born in 1974 (40 years old chronologically):
Their mom's actually shared a labor and delivery room!

Butthead - known: Devout Buddhist, very athletic, non smoker with a family history of diabetes

Beavis' life expectancy is 57 (72-7-8)
Butthead's life expectancy is 84 (72+6+2+6-2)

Beavis has expended 70.2% (40/57) of his life expectancy
Butthead has expended 47.6% (40/84) of his life expectancy

Despite sharing a birthday:
Bevis' biological age is 50.5 years (.702*72)
Butthead's biological age is 34.3 years (.476*72)
