MAIN OUTCOME MEASURE
Hazard ratio of death adjusted for sex, year of entry to study, and
socioeconomic status.
RESULTS
Subjects who retired early at 55 and who were still alive at 65
had a significantly higher mortality than those who retired at 65 (haz-
ard ratio 1.09 to 1.73). Mortality was also significantly higher for
subjects in the first 10 years after retirement at 55 compared with
those who continued working (1.89, 1.58 to 2.27). After adjustment,
mortality was similar between those who retired at 60 and those who
retired at 65 (1.06, 0.92 to 1.22). Mortality did not differ for the first
five years after retirement at 60 compared with continuing work at 60
(1.04, 0.82 to 1.31).
CONCLUSIONS
Retiring early at 55 or 60 was not associated with better survival
than retiring at 65 in a cohort of past employees of the petrochemical
industry. Mortality was higher in employees who retired at 55 than in
those who continued working.
