Adherence
Engaging in moderate-to-high leisure-time physical activity (LTPA) or objectively measured brisk walking significantly reduces all-cause mortality and increases life expectancy in individuals with multimorbidity (two or more chronic conditions), with benefits comparable to or exceeding those seen in individuals without multimorbidity.
If you have two or more chronic conditions, you do not need to perform extreme exercise to gain significant health benefits. Aim for moderate activity, such as 150 minutes of moderate-intensity exercise per week, or as little as 10 minutes of brisk walking daily. This level of activity is associated with a substantial increase in life expectancy (over 3 years at age 45) and reduced mortality risk, comparable to those without chronic conditions.
In participants with multimorbidity, at the age of 45 years, moderate and high LTPA were associated with an average of 3.12 (95% CI 2.53, 3.71) and 3.55 (2.34, 4.77) additional life years, respectively, compared to low LTPA... These findings were similar for participants without multimorbidity.
Why this rating
Large longitudinal cohort (UK Biobank, n=491,939) with objective and subjective measures, though observational design limits causal inference.
