Adherence
Telephonic wellness coaching based on motivational interviewing produces a statistically and clinically significant reduction in BMI (greater than 1 unit) over 12 months in adults with overweight or obesity.
If you are struggling with weight management, consider enrolling in a telephonic wellness coaching program offered by your health plan. These programs typically use motivational interviewing, where a coach helps you set goals and build intrinsic motivation to change habits like diet and exercise. You can expect about two phone calls over a year, which has been shown to significantly reduce BMI in adults with overweight or obesity.
Wellness coaching participants had a significant upward trend in BMI in the 12 months before their first wellness coaching session and a significant downward trend in BMI in the 12 months after their first session equivalent to a clinically significant reduction of greater than one unit of baseline BMI (P < 0.01 for both).
Why this rating
The study uses a robust quasi-experimental design (interrupted time series with propensity-score matching) on a large population (n=954 vs n=19,080), though it is not a randomized controlled trial.
