Abstract

AIMS:

To assess self-reported lifetime prevalence of cardiovascular disease (CVD) among colorectal cancer survivors, and examine the cross-sectional and prospective associations of lifestyle factors with co-morbid CVD.

METHODS:

Colorectal cancer survivors were recruited (n=1966). Data were collected at approximately 5, 12, 24 and 36 months post-diagnosis. Cross-sectional findings included six CVD categories (hypercholesterolaemia, hypertension, diabetes, heart failure, kidney disease and ischaemic heart disease (IHD)) at 5 months post-diagnosis. Longitudinal outcomes included the probability of developing (de novo) co-morbid CVD by 36 months post-diagnosis. Lifestyle factors included body mass index, physical activity, television (TV) viewing, alcohol consumption and smoking.

RESULTS:

Co-morbid CVD prevalence at 5 months post-diagnosis was 59%, and 16% of participants with no known CVD at the baseline reported de novo CVD by 36 months. Obesity at the baseline predicted de novo hypertension (odds ratio [OR]=2.20, 95% confidence intervals [CI]=1.09, 4.45) and de novo diabetes (OR=6.55, 95% CI=2.19, 19.53). Participants watching >4h of TV/d at the baseline (compared with <2h/d) were more likely to develop ischaemic heart disease by 36 months (OR=5.51, 95% CI=1.86, 16.34).

CONCLUSION:

Overweight colorectal cancer survivors were more likely to suffer from co-morbid CVD. Interventions focusing on weight management and other modifiable lifestyle factors may reduce functional decline and improve survival.
