Natural history of leisure-time physical activity and its correlates : Associations with mortality from all causes and cardiovascular disease over 28 years.
The association between leisure-time physical activity and 28-year (1965-1993) risk of death from all causes and cardiovascular disease was studied in 6,131 adults who participated in the Alameda County Study in Northem California.
Because study participants were interviewed on a number of occasions, it was possible to include in the analyses information on changes over time in levels of leisure-time physical activity as well as changes in a wide variety of other risk factors.
There were 47,616 person-years of observation for males (639 deaths from all causes and 321 from cardiovascular disease) and 57,666 person-years of observation for females (587 deaths from all causes and 388 from cardiovascular disease).
In analyses in which only the baseline values of all covariates were included, a four-point increase on the leisure-time physical activity scale, the interquartile range, was associated with reduced risk of death from all causes (relative risk (RR)=0.90,95% confidence interval (CI) 0.83-0.99) and cardiovascular disease (RR=0.85,95% CI 0.75-0.97).
When time-varying information on leisure-time physical activity and all other covariates was included, there was still a protective effect for all-cause and cardiovascular disease mortality (RR=0.84,95% CI 0.77-0.92 and RR=0.81,95% CI 0.71-0.93, respectively). (...)
