title: Self-Reported Physical Activity Levels of Older Cancer Survivors: Results from the 2014 National Health Interview Survey.
abstract: OBJECTIVE
  To examine adherence to the American College of Sports Medicine and American Cancer Society guidelines on leisure-time aerobic and muscle-strengthening physical activity (PA) of older cancer survivors.
  
  
  METHODS
  Cross-sectional study based on the 2014 National Health Interview Survey.
  
  
  METHODS
  United States.
  
  
  METHODS
  Young-old (65-74) (n = 627), old-old (≥75) (n = 656), and middle-aged (45-64) (n = 786) cancer survivors and adults without cancer (n = 18,369), stratified according to the same age groups.
  
  
  METHODS
  Weighted percentages were used to describe sociodemographic and health-related characteristics of the study population. Unadjusted and adjusted predicted probabilities from generalized ordered and multinomial logistic regressions were estimated to examine levels of aerobic and muscle-strengthening PA in the study population.
  
  
  RESULTS
  Cancer survivors and those without a cancer diagnosis had similarly low rates of adherence to PA guidelines according to age group. In unadjusted analyses, the age effect was statistically significant in long-term cancer survivors only. Adjusting for sociodemographic and health-related characteristics, on average, 34.0% of young-old and 35.4% of old-old cancer survivors engaged in sufficient levels of aerobic PA, versus 44.3% of their middle-aged counterparts (P's <.05). Approximately 10% of older cancer survivors met aerobic and muscle-strengthening guidelines, compared with 19.1% of middle-aged cancer survivors (P = .001).
  
  
  CONCLUSIONS
  Adherence to the recommended levels of leisure-time aerobic and muscle-strengthening PA is lower in older than middle-aged cancer survivors in the United States. Greater efforts must be made to encourage and support PA participation in this population.
