Lifestyle index for mortality prediction using multiple ageing cohorts in the USA, UK and Europe.

ABSTRACT: Current mortality prediction indexes are mainly based on functional morbidity and comorbidity, with limited information for risk prevention. This study aimed to develop and validate a modifiable lifestyle-based mortality predication index for older adults. Data from 51,688 participants (56% women) aged ≥50 years in 2002 Health and Retirement Study, 2002 English Longitudinal Study of Ageing and 2004 Survey of Health Ageing and Retirement in Europe were used to estimate coefficients of the index with cohort-stratified Cox regression.

The lifestyle index includes smoking, drinking, exercising, sleep quality, BMI, sex and
