Estimate remaining life expectancy adjusted for modifiable lifestyle factors.
Adjustments here reflect population-level associations rather than individual causation, and they are not independent of one another. Smoking carries by far the largest single association of the factors included. Life expectancy at a given age exceeds life expectancy at birth, because having survived to that age already removes early mortality from the calculation.
Life Expectancy
Projected expectancy = population baseline adjusted for sex and modifiable factors
This reproduces a published formula for educational and reference use only. It is not a diagnostic tool, does not account for individual clinical context, and must not be used to make or change treatment decisions. Clinical assessment by a qualified healthcare professional is always required. This is a rough educational illustration of population associations, not a personal prognosis. It cannot account for genetics, medical history or circumstances. Do not use it for financial, insurance or medical planning; consult qualified professionals instead.
