Previous studies suggest that health-related quality of life (HRQoL) is impaired after a traumatic spinal cord injury (TSCI) and may be worse with older age. This study determines whether the expectations to achieve normal HRQoL in Canadians following a TSCI is indeed influenced by older age. A prospective observational study was conducted on adult patients admitted acutely at a single level-1 trauma center after a TSCI. We assessed HRQoL using the SF-36 physical and mental component summary (PCS and MCS) scores obtained one year post injury. Using Canadian normative HRQoL data matched for age and sex, we defined normal PCS and MCS as a score within 2 standard deviations with respect to the normative Canadian mean. We then conducted logistic regression models to determine the relationship between age at the time of injury and the likelihood of achieving normal PCS and MCS, while controlling for confounding variables. Overall, 39.3% of individuals displayed normal PCS, whereas 80.4% displayed normal MCS. When adjusted for confounders, older age remained significantly associated with increased likelihood of achieving normal PCS (Odds Ratio: 1.03; 95% Confidence Interval: 1.01-1.06; P=0.002). We observed no association between age and achieving normal MCS. A significant proportion of individuals can achieve a normal HRQoL similar to their healthy peers following a TSCI, particularly for the mental component. When compared to younger individuals, older individuals are more likely to achieve normal PCS and present a similar likelihood for achieving normal MCS.
