Summary: | Background
Allostatic load (AL) has been linked to an increased risk of death in various populations. However, to date, there is no research specifically investigating the effect of AL on mortality in older cancer survivors.
Aims
To investigate the association between AL and mortality in older cancer survivors.
Method
A total of 1291 adults aged 60 years or older who survived for ≥1 year since cancer diagnoses were identified from the 1999 to 2010 National Health and Nutrition Examination Survey. AL was the exposure of interest incorporating nine clinical measures/biomarkers; one point was added to AL if any of the measures/biomarkers exceeded the normal level. The sum of points was categorized as an ordinal variable to reflect low, moderate, and high ALs. Our outcomes of interest were all‐cause, cancer‐specific, and cardiovascular disease–specific mortality. Death was identified by linkage to the National Death Index. Multivariable Cox proportional hazards models were used to estimate adjusted hazard ratio (aHR) and 95% confidence intervals (CI) of mortality by AL category.
Results
Overall, 53.6% of participants were male and 78.4% were white. The mean age of study participants at interview was 72.8 years (standard deviation = 7.1). A total of 546 participants died during the follow‐up (median follow‐up time: 8.0 years). Among them, 158 died of cancer, and 106 died of cardiovascular events. Results from multivariable Cox proportional hazards models showed that higher ALS was positively associated with higher all‐cause mortality (ALS = 4–9 vs. ALS = 0–1: aHR = 1.52, 95% CI = 1.17–1.98, p‐trend |
