Abstract 2000

Background

The diagnosis of cancer can motivate survivors to modify lifestyles, typically involving diet and physical activity. Few data have reported pre- and post-diagnostic lifestyle habits in Chinese population.

Methods

In an on-going prospective cohort study which involved 1462 Chinese women with early-stage breast cancer, we evaluated dietary intake and lifestyle factors pre- and post- breast cancer diagnosis. Validated food frequency questionnaires were used to evaluate dietary intake. Leisure time physical activity was measured by a modified Chinese Baecke questionnaire. This report compared changes of dietary intake and physical activity between 12 months before and 18 months after diagnosis of breast cancer.

Results

Intake of whole grains, refined grains, fruits, vegetables, eggs, and nuts increased significantly post-diagnosis (Range, 54%-72% increase; P 

Conclusions

In this cohort study, Chinese breast cancer patients reported significant changes in dietary intake and increased physical activity level and a higher proportion met the WCRF/AICR Cancer Prevention recommendations after cancer diagnosis. These findings provided crucial information on lifestyle behaviors in Chinese breast cancer survivors, and provided information to healthcare professionals on survivors’ health and quality of life.
