PMID 29746264WHAT IT FOUND
Female cancer survivors had modest guideline adherence.
Supervised exercise increased physical activity versus control group calls, but did not improve diet or BMI. Overall adherence stayed modest and was similar at 12 months.
Key findings
01Total MET-minutes/week increased in the exercise group and decreased in the control group, and the between-group difference was significant at 6 and 12 months.
02BMI and fruit and vegetable intake did not differ between groups over 12 months.
03Mean total adherence score was 4.2 of 8 at baseline, 4.9 at 6 months and 4.8 at 12 months, and both groups had the same average score at 12 months.

What it does not show
The sample was 154 mostly white, highly educated, employed women in Connecticut, so results may not apply to more diverse female cancer survivors. The exercise group was younger than the control group (50.6 vs 53.1 years). Attrition was 11.6%, though it did not differ between groups. Diet was self-reported with 4-day records, which may have been burdensome, could have changed what participants ate, and may have been affected by social desirability.
Declared interests
The authors reported no conflicts of interest.
The easy way to misread this
Do not conclude that supervised exercise improves diet or weight. It increased physical activity, but BMI, fruit and vegetable intake, fiber and red meat intake did not differ between groups over 12 months, and total adherence was similar at 12 months.
