Adherence
Current smoking status is a significant independent predictor of attrition (dropping out) from weight loss interventions.
If you smoke, be aware that you are statistically more likely to drop out of a weight loss program. Programs should pay specific attention to smokers to help them stay engaged and adhere to the diet.
GoodSupportsHIGH confidence
Attrition was higher in... current smokers (25% vs. 14% among maintainers, p < 0.04).
Why this rating
RCT data showing statistically significant difference in attrition rates between smokers and non-smokers.
