title: Health behavior changes in white and African American prostate cancer survivors.
abstract: Prostate cancer prognosis may be improved by healthy behaviors; however, little is known regarding whether prostate cancer survivors make health behavior changes after diagnosis, and there are no data on racial/ethnic differences. This study explored patterns of and factors that influence healthy behavior changes in diet, physical activity, and dietary supplement use among whites and African Americans (n = 30) aged 45 to 70 years, approximately 1 year after diagnosis with localized prostate cancer. Data were collected by telephone using semistructured qualitative interviews. The mean participant age was 59.6 years, 77% had attended college, 87% were married, and 22% were retired. Most (58%) had improved their diet since diagnosis, defined as eating more fruits/vegetables and less fat. Although 77% reported regular use of at least 1 dietary supplement before diagnosis, several discontinued use after diagnosis. Sixty-seven percent exercised regularly before diagnosis, and most of these (75%) continued after diagnosis; however, time and health constraints were barriers. Physician recommendation and family support strongly influenced positive changes. Except for more postdiagnosis dietary improvements in African Americans, there were few racial differences in patterns/motives for behavior changes. Most respondents were motivated to maintain and/or adopt healthy behavioral changes after diagnosis. Nurses/physicians are encouraged to inform their prostate cancer patients about the benefits of healthy eating and regular exercise and about the absence of scientific evidence regarding the benefits/risks of most supplements, particularly herbal formulations.
