title: Control of cardiovascular risk factors among adult cancer survivors: a population-based survey.
abstract: BACKGROUND
  Cardiovascular disease (CVD) is a major cause of morbidity and mortality in cancer survivors, with the risk increasing significantly with the presence of multiple cardiac risk factors (RF). The proportion of cancer survivors at elevated risk of CVD on the basis of multiple RF is unknown.
  
  
  METHODS
  The National Health and Nutrition Examination Survey (NHANES 1999-2006) was used to examine the proportion of cancer survivors with multiple RF (≥2RF) and those at high cardiac risk (≥4 RF) compared with matched controls. RF (hypertension, hypercholesterolemia, weight, exercise, smoking) were defined according to AHA/ACC.
  
  
  RESULTS
  A total of 1,227 cancer survivors and 4,782 controls were identified. The majority of both cancer survivors and controls had multiple RF (91.5 vs. 89.9%) with a substantial proportion at high cardiac risk (35.2 vs. 32.6%). Compared to controls, survivors were more likely to be smokers (34.5 vs. 25.7%, p = 0.001), but less likely be overweight (67.2 vs. 72.0%, p = 0.02). There was no significant difference in the proportion with hypertension (30.6 vs. 30.8%), hypercholesterolemia (52.4 vs. 54.7%) or low exercise (75.6 vs. 73.0%). Among survivors, only age was associated with RF; with older survivors significantly more likely to have poor control than younger survivors (p = 0.005).
  
  
  CONCLUSIONS
  The prevalence of multiple RF was similar but suboptimal among cancer survivors and controls. Cardiac RF control, particularly among older survivors, is an important area of focus for improvement in survivorship care.
