Cardiovascular disease in adolescent and young adult cancer survivors: Impact of sociodemographic and modifiable risk factors

BackgroundThere is a growing population of adolescent and young adult (AYA) cancer survivors (ages 15-39 years), and they have an elevated risk of developing cardiovascular disease (CVD). Little is known about the contribution of sociodemographic and modifiable factors to the risk of CVD in AYA survivors and whether these factors differentially modulate their risk compared with that in the general population. The current study sought to fill these gaps. MethodsSelf-reported data from the US National Health Interview Survey (2009-2018) were used to identify AYA cancer survivors (>= 2 years postdiagnosis) and age-matched and sex-matched controls. The risk of CVD based on sociodemographic factors (sex, race/ethnicity, income, education) and modifiable risk factors (diabetes, body mass index, smoking, physical activity) was determined within and between survivors and controls using logistic regression models. ResultsIn total, 4766 AYA cancer survivors and 47,660 controls were included. The odds of CVD were significantly higher in survivors than in controls by sex, race/ethnicity, income, education, smoking status, and physical activity. An annual household income <$50,000 disproportionately increased the odds of CVD in survivors. One third of survivors reported no moderate-to-vigorous-intensity physical activity (MVPA). Performing any MVPA lowered the odds of CVD in survivors (odds ratio, 0.61; 95% CI, 0.450.81) and controls (odds ratio, 0.68; 95% CI, 0.61-0.77). ConclusionsSociodemographic and modifiable risk factors increased the odds of CVD in AYA survivors, in some cases disproportionately, compared with controls. Understanding health behavior trajectories among different sociodemographic populations is needed to identify opportunities to lower the risk of CVD. Performing any MVPA is particularly important for AYA survivors.

Automated summary

This study aimed to investigate the risk of cardiovascular disease in adolescent and young adult cancer survivors and its differential modulation compared to the general population. The results showed that sociodemographic and modifiable risk factors increased the odds of cardiovascular disease in survivors, with physical activity playing a particularly important role.
