Intervention using behavior modification techniques to improve the lifestyle of high-risk metabolic syndrome patients.
Rika Mangyo, Takeshi Arai
PMID 32158079WHAT IT FOUND
In 21 teachers at high risk, 12 weeks of leaflets plus goal-setting, self-monitoring and weekly email feedback lowered waist and weight compared with leaflets alone.
Activity, food intake and blood fats did not differ.
Key findings
01The intervention group changed by −3.2 kg in weight, −0.9 BMI, and −3.4 cm in abdominal circumference, compared with −0.8 kg, −0.2 BMI, and 1.2 cm in the control group.
02The differences in body weight, BMI, and abdominal circumference between groups were significant (p=0.013, p=0.013, p=0.001).
03There were no differences between groups in changes to total physical activity, total energy intake, or blood lipid levels.

What it does not show
The sample was small (21 participants), and the control group was all male. The control group’s behavior was not recorded, so it is unclear how much lifestyle difference explained the waist and weight results. The intervention was a bundle of leaflets, goal setting, self-recording and feedback, so the effect of any one part cannot be separated. The paper does not name a single primary outcome, and several outcomes were tested.
Declared interests
The authors declared no conflicts of interest and reported no funding.
The easy way to misread this
Do not conclude that behavior modification alone caused the waist reduction. The intervention also included leaflets, goal setting, self-recording and weekly feedback, and the control group’s behavior was not recorded.
