OBJECTIVE: To evaluate the association of household income and formal education
with risk of mortality after spinal cord injury (SCI). DESIGN: Cohort study.
SETTING: Twenty hospitals designated as Model SCI Systems of care in the United
States. PARTICIPANTS: Adults (N=8027) with traumatic SCI, seen in one of the
Model SCI Systems, who had at least 1 follow-up assessment between 1995 and 2006.
All participants were at least 1 year postinjury at the time of assessment. There
were 57,957 person-years and 1036 deaths. The follow-up period started with the
first assessment between 1995 and 2006 and went until either the date of death or
March 2009. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Mortality
status was determined by routine follow-up supplemented by using the Social
Security Death Index. A logistic regression model was developed to estimate the
chance of dying in any given year. RESULTS: Educational status and income were
significantly predictive of mortality after adjusting for age, sex, race, and
severity of injury. Compared with those with household income of $75,000 or
greater, the odds of mortality was greater for those who had income between
$25,000 and $75,000 (1.61) and still higher for those with less than $25,000 a
year (2.41). Life expectancy differed more as a function of household income than
the economic subscale of the Craig Handicap Assessment and Reporting Technique.
CONCLUSION: There was a clear gradation in survival based on familial income
(high, middle, low), not just an effect of the lowest income.
