A Weight Management Intervention for Overweight Chinese Cancer Survivors

Lose Little, Live Longer: A Randomised Controlled Feasibility Trial on a Diet-plus-exercise Weight Management Intervention for Overweight Chinese Cancer Survivors

This study aims to conduct a feasibility trial to examine the feasibility and acceptability of conducting a randomized controlled trial that evaluates the effect of the weight management intervention on anthropometric measures (body weight and BMI), dietary quality, physical activity levels, physical and psychosocial functioning, self- efficacy for weight loss and quality of life.

The primary aim of the proposed study is to assess the feasibility and acceptability of conducting a randomized controlled trial (RCT) that evaluates an adaptive weight management intervention, tailored to Chinese cancer survivors with overweight/obesity after the completion of cancer survivorship care, to improve anthropometric measures (body weight and BMI), dietary quality, physical activity levels, physical and psychosocial functioning, self-efficacy for weight loss and quality of life. According to the Consolidation Standards of Reporting Trials (CONSORT) guidelines for reporting feasibility trials, hypothesis setting for a feasibility trial is not recommended, given that pilot trials are often underpowered to detect difference which instead should be the aim of the main trial.

Inclusion Criteria:

• Chinese cancer survivors attending the one-off face-to-face survivorship care clinic
• who are Cantonese- or Mandarin- speaking
• aged 18 or above
• diagnosed with early-stage disease (stage 0-II)
• have completed primary and adjuvant treatments such as chemotherapy and radiotherapy
• and with a BMI ≥ 23 kg/m2, as indicative as overweight or obesity using Asia-Pacific BMI cutoffs at 3-months reassessment

Exclusion Criteria:

• Non-Chinese survivors with advanced or metastatic disease
• who have communication difficulties, mobility impairment or cognitive disabilities
