Adherence
Baseline sleep disturbance significantly moderates the efficacy of behavioral weight loss interventions in breast cancer survivors, with poor sleepers achieving significantly less weight loss than better sleepers.
If you are a breast cancer survivor trying to lose weight, your sleep quality matters as much as your diet. If you have poor sleep, standard weight loss programs may be half as effective for you. Consider getting your sleep evaluated and treated before or during your weight loss journey to maximize results.
BWL has greater effects in breast cancer survivors with better versus worse sleep. ... Among poor sleepers, weight loss was −3.15% (SE: 1.58%) and −2.44% (SE: 2.40%) at 6 (p = 0.056) and 12 months (p = 0.321), respectively.
Why this rating
Randomized controlled trial with stratified analysis, though the subgroup analysis is exploratory/post-hoc.
