Adherence
Among individual lifestyle factors, smoking cessation provides the largest survival benefit and life expectancy gain for individuals with multimorbidity, outweighing the benefits of physical activity, diet, or alcohol moderation.
If you smoke, quitting is the most powerful single action you can take to extend your life, especially if you have chronic conditions. It can add nearly 5-6 years to your life expectancy, far more than diet or exercise changes alone.
GoodSupportsHIGH confidence
For individual lifestyle factors, no current smoking was associated with the largest survival benefit.
Why this rating
