Abstract
BACKGROUND: In 2006, the IOM released a report citing the importance of “survivorship plans” to improve quality-of-life. Little has been done to evaluate their efficacy with regard to uptake of dietary and lifestyle recommendations.
METHODS: Women with early-stage breast cancer were randomized within 6 weeks of completing adjuvant therapy to a survivorship intervention or a control group. Randomization was stratified by ethnicity and subjects were not aware that they were randomized. All subjects were provided the NCI publication, “Facing Forward: Life after Cancer Treatment.” The survivorship intervention group also met with a nurse (1 hour) and nutritionist (1 hour) to receive a treatment summary, surveillance and personalized lifestyle recommendations, based on guidelines from the American Cancer Society and American Institute for Cancer Research. At baseline, 3 and 6 months, both groups completed questionnaires on diet, lifestyle, and perceived health. Linear regression analyses adjusted for ethnicity evaluated the effects of the intervention on comprehension and uptake of lifestyle recommendations. Additional models were run to evaluate the interaction between intervention and ethnicity.
RESULTS: Among 126 women (60 control group, 66 survivorship intervention) mean age was 54 yrs, 48% were Hispanic, and randomized groups were well-balanced by baseline characteristics. Of note, at baseline, compared to non-Hispanics, Hispanics reported lower SES, poorer knowledge of healthy lifestyle behaviors (e.g., diet, physical activity, weight, dietary supplements), lower intake of fruits and vegetables, less recreational physical activity, lower consumption of alcohol, and a lower overall health rating (all P&lt;0.05). After adjusting for ethnicity, at month 3 the intervention group compared to the control group reported greater knowledge of how to eat a healthy diet (P = 0.047), greater knowledge of appropriate use of dietary supplements (P = 0.006), higher levels of physical activity (P = 0.03), and higher intake of fish (P = 0.005). At month 6, the only difference that persisted was greater knowledge of a healthy diet (P = 0.01). In models assessing an interaction between intervention condition and ethnicity, compared to Hispanics, the intervention had a stronger effect on increasing non-Hispanics’ belief that a healthy diet was important to prevent breast cancer recurrence (P = 0.02).
CONCLUSIONS: Compared to only receiving written survivorship materials, a survivorship intervention that included written materials plus a 1 hour personalized lifestyle counseling session was associated with short-term increased knowledge of lifestyle recommendations, change in physical activity and change in dietary behaviors among a multi-ethnic group of breast cancer survivors. Behavioral effects were not observed beyond 3 months. A single 1 hour lifestyle consultation is likely not enough to achieve and maintain lifestyle recommendations. To facilitate long-term behavioral change among breast cancer survivors in the adjuvant setting, culturally competent behavioral interventions should be developed to increase knowledge of and the capabilities needed to meet lifestyle recommendations.
