Background:
The long-term health association of the leisure-time and transport-related physical activity domains of the International Physical Activity Questionnaire (IPAQ) have not been established in Latin American settings. We aimed to quantify the 7-year all-cause mortality risk associated with levels of leisure-time and transport-related physical activity.
Methods:
Ongoing prospective cohort study conducted in four sites in Peru. People ≥35 years were randomly selected from the general population in each study site. The exposures were leisure-time and transport-related physical activity (IPAQ) at baseline. The outcome was all-cause mortality based on information retrieved from national records. Cox regression and sensitivity analyses were conducted.
Results:
There were 3601 people (mean age 55.8 years, 51.5% women). Greater levels of physical activity were associated with lower risk of all-cause mortality, an observation confirmed in sensitivity analyses. Compared to those with low levels of physical activity, leisure-time(≥500 MET-min/week) and transport-related (500-1499 and ≥1500 MET-min/week) physical activity were associated with 70% (95% CI: 3%-90%), 43% (95% CI: 18%-61%), and 42% (95% CI: 8%-63%) lower all-cause mortality, respectively.
Conclusions:
Greater levels of leisure-time and transport-related physical activity were associated with a strong reduction in the risk of all-cause mortality across different geographical sites.
