Authors' conclusion

Life course adversities are associated with increased risks of premature mortality and reduced life expectancy.

Study context

Population
UK Biobank participantsLE8 data for 94,289
Participants
148,137 participants
Exposure
≥2 adversities vs no adversity, in childhood and in adulthood
Outcome
Premature mortality (death before age 75) and life expectancy
Follow-up
Median 13.4 years

Main finding

As reported in the abstract

Further findings

Outcomeyears of life lost (years) (95% CI)
Years of life lost at age 45 — ≥2 adversities in childhood vs No adversity1.026 (0.584–1.468)

Premature mortality and life expectancy, stratified by LE8

Associations attenuated and eventually eliminated as LE8 levels increased
