    Area of Science:

    • Integrative and Complementary Medicine
    • Public Health
    • Epidemiology

    Background:

    • The chiropractic profession promotes the idea that chiropractic care enhances longevity.
    • This claim suggests that individuals receiving chiropractic care experience extended lifespans.
    • Assessing the mortality rates of chiropractors can provide insight into the validity of this assertion.

    Purpose of the Study:

    • To evaluate the validity of the common chiropractic assertion: "Chiropractic Adds Life to Years and Years to Life."
    • To compare the lifespan of chiropractors to the general population and medical doctors.
    • To determine if chiropractors, as primary recipients of chiropractic care, exhibit increased longevity.

    Main Methods:

    • Analysis of mortality data from two distinct sources: obituary notices from "Dynamic Chiropractic" (1990-2003) and biographies from "Who Was Who in Chiropractic - A Necrology" (1969-1979).

  • Comparison of chiropractors' mean age at death with national average lifespan and the lifespan of medical doctors.

    • Main Results:

    • The mean age at death for chiropractors was found to be 73.4 years from one data source and 74.2 years from another.
    • This average lifespan for chiropractors is below the national average lifespan of 76.9 years.
    • Chiropractors' mean age at death is also significantly lower than that of their medical doctor counterparts, who have a mean age at death of 81.5 years.

    Conclusions:

    • The study found no empirical evidence to support the chiropractic claim that chiropractic care extends life expectancy.
    • The mortality data suggests that chiropractors do not live longer than the general population or medical doctors.
    • The findings challenge the widely promoted assertion regarding the life-extending benefits of chiropractic care.
