Internet users more likely to engage in cancer-preventive behaviors PHILADELPHIA — Older men and women who used the internet were more likely to participate in screening for colorectal cancer, participate in physical activities, eat healthily, and smoke less, compared with those who did not use the internet, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

A large, population-based, cohort study of older adults in England, called the English Longitudinal Study of Aging, collected data from men and women aged 50 or older, and found that men and women who were consistent internet users were twice as likely to participate in colorectal screening than nonusers. Both men and women who used the internet consistently were also 50 percent more likely to take part in regular physical activity, 24 percent more likely to eat at least five servings of fruits and vegetables daily, and 44 percent less likely to be current smokers. There was, however, no association between internet use and participation in breast cancer screening among women.

"We accounted for sociodemographic factors that influence internet use and various measures of physical capabilities and cognitive function that decline with age, and still found an association between internet use and cancer-preventive behaviors," said Christian von Wagner, Ph.D., senior lecturer in behavioral research in early diagnosis of cancer at the University College London, United Kingdom. "The interesting aspect here is a dose-response relationship between internet use and cancer preventive-behaviors: Intermittent users were more likely to have cancer-preventive behaviors than never-users, and consistent users were more likely to have cancer-preventive behaviors than intermittent users."

Von Wagner and colleagues, however, identified a "digital divide." Internet use was higher in younger, male, white, wealthier, and more educated participants and lower in older, less wealthy, and nonwhite individuals with physical disabilities. "It is important that policymakers recognize the role internet use plays in influencing inequalities in cancer outcomes, and help increase access to the internet among this demographic," he said.

The researchers used data from 5,943 respondents who answered questions collected in wave one in 2002, and were followed up with questions every two years in waves two to five, until 2011. Questions included internet/email use, self-reported colorectal and breast cancer screening, physical activity, eating habits, physical and cognitive abilities, and demographics.

Among the study participants, 41.4 percent reported not using the internet, 38.3 percent reported using the internet in waves one to three (intermittent users), and 20.3 percent reported using the internet in all five waves (consistent users).

About the American Association for Cancer Research Founded in 1907, the American Association for Cancer Research (AACR) is the world's oldest and largest professional organization dedicated to advancing cancer research and its mission to prevent and cure cancer. AACR membership includes more than 34,000 laboratory, translational, and clinical researchers; population scientists; other health care professionals; and cancer advocates residing in more than 90 countries. The AACR marshals the full spectrum of expertise of the cancer community to accelerate progress in the prevention, biology, diagnosis, and treatment of cancer by annually convening more than 20 conferences and educational workshops, the largest of which is the AACR Annual Meeting with more than 18,000 attendees. In addition, the AACR publishes eight peer-reviewed scientific journals and a magazine for cancer survivors, patients, and their caregivers. The AACR funds meritorious research directly as well as in cooperation with numerous cancer organizations. As the scientific partner of Stand Up To Cancer, the AACR provides expert peer review, grants administration, and scientific oversight of team science and individual grants in cancer research that have the potential for near-term patient benefit. The AACR actively communicates with legislators and policymakers about the value of cancer research and related biomedical science in saving lives from cancer.
