Obesity

The Impact of Baseline Sleep as a Potential Moderator of Weight Loss Intervention in Breast Cancer Survivors: Results From the POWER ‐Remote Trial

Obesity (Silver Spring)Published Secondary analysis of the POWER-Remote randomised trial

Authors' conclusion

BWL has greater effects in breast cancer survivors with better versus worse sleep. Studies should evaluate whether sleep disturbance treatment augments weight loss.

Study context

Population
Women with prior stage 0-III breast cancer with BMI ≥ 25 kg/m²
Participants
47 vs 46
Comparison
Behavioral weight loss vs self-directed approach, by baseline sleep
  • Behavioral weight loss (BWL)n = 47
  • Self-directedn = 46reference
Primary endpoint
Weight loss, moderated by baseline sleep disturbance (NIH PROMIS Adult Sleep Disturbance Short Form)
Follow-up
6 and 12 months
Methodological detailsmoderator analysis, stratified by baseline sleep
  • Moderator analysis
  • Stratified by baseline sleep

Primary result

As reported in the abstract

Weight loss by baseline sleep (BWL vs self-directed)
6 months; SE 1.42%
weight loss difference, better sleepers −6.16 %; P < 0.001
12 months; SE 2.02%
weight loss difference, better sleepers −7.53 %; P = 0.001
6 months; SE: 1.58%
weight loss difference, poor sleepers −3.15 %; P = 0.056
12 months; SE: 2.40%
weight loss difference, poor sleepers −2.44 %; P = 0.321
