Childhood cancer survivors are not always healthier adults

12 Aug 2014

People who have survived cancer as a child do not always lead a healthier lifestyle once they are adults. For instance, they eat less healthy than their peers.

In particular, in a report derived from a National Cancer Institute-funded study of childhood cancer survivors known as the Chicago Healthy Living Study, investigators found that childhood cancer survivors in no way adhere more closely to guidelines on healthy eating than their cancer-free peers. The findings are published in Springer's Journal of Cancer Survivorship.

Childhood cancer survivors face different health-care challenges and are more susceptible to dying earlier than the general population. They have a higher risk of second cancers, heart disease, body weight disorders and psychosocial problems. Therefore the American Cancer Society Guidelines on Nutrition and Physical Activity encourages the efforts of cancer survivors to lead healthier lifestyles.

No difference in following guidelines

Because so little is known about how well cancer survivors adhere to these guidelines, Chloe Berdan and colleagues examined selected data from the Chicago Healthy Living Study participants. The University of Illinois investigative team led by Drs. Stolley and Sharp conducted structured health-focused interviews with 431 childhood cancer survivors and 361 people who never had the disease. The survivors, aged between 18 and 59 years old, were all diagnosed with a malignant cancer before their 21st birthdays.

No marked difference was found between how survivors and members of the control group adhered to the overall American Cancer Society guidelines.

Survivors: 

  • had on average a body mass index (BMI) of about 1.2 kg/m² lower than that of members of the control group
  • smoked less
  • consumed less fiber: in fact, only about one in every ten survivors (10.2%) met fiber recommendations
  • only 17.7% ate five fruits or vegetables per day
  • were better at meeting the goal of at least five hours of moderate activity per week (60.5%) than to sticking to any of the other guidelines
  • on average scored under 50% for the quality of their diets.

The 0.7% of survivors who actually adhered fully to the guidelines tended to be women, non-smokers and people with a good view of their own health.

"There is still much room for improvement in educating and encouraging survivors to follow healthier diets and lifestyles," says Berdan. "Adopting such behavior during early adulthood may have a lasting impact on their quality of life and overall survival."
