title: A Web-based self-management exercise and diet intervention for breast cancer survivors: pilot randomized controlled trial.
abstract: BACKGROUND
  Regular exercise and dietary practices have been shown to affect the health-related quality of life (HRQOL) and survival of breast cancer patients.
  
  
  OBJECTIVE
  The current study aimed to investigate whether the WSEDI was a feasible and primarily effective method for promoting exercise and dietary behaviours for breast cancer patients.
  
  
  METHODS
  A 12-week randomized, controlled trial.
  
  
  METHODS
  Oncology outpatient treatment clinics at 3 university hospitals and 1 National Cancer Center in South Korea.
  
  
  METHODS
  Fifty-nine breast cancer patients who had received curative surgery and completed primary cancer treatment within 12 months prior to the study and who had been diagnosed with stage 0-III cancers within 2 years prior to the study were recruited.
  
  
  METHODS
  Participants were randomly assigned to either the intervention group, which used a Web-based self-management exercise and diet intervention program incorporating transtheoretical model (TTM)-based strategies (n=29), or to the control group, which used a 50-page educational booklet on exercise and diet (n=28). The intervention efficacy was measured at the baseline and 12 weeks via a Web-based survey that addressed the promotion of exercise and consumption of 5 servings of fruits and vegetables (F&V) per day, dietary quality, HRQOL, anxiety, depression, fatigue, motivational readiness, and self-efficacy.
  
  
  RESULTS
  The proportion of subjects who performed at least moderate-intensity aerobic exercise for at least 150 min per week; ate 5 servings of F&V per day; and had overall improvements in dietary quality, physical functioning and appetite loss (HRQOL), fatigue, and motivational readiness was greater in the intervention group than in the control group. The self-efficacy with respect to exercise and F&V consumption was greater in the intervention group than in the control group. A Web-based program that targets changes in exercise and dietary behaviours might be effective for breast cancer survivors if the TTM theory has been used to inform the program strategy, although further research with a larger sample size is required to enable definitive conclusions.
