Exercise can extend life span by 4–6 years, a level greater than the 1–4 years of life-shortening effect from high serum uric acid (sUA), a study concluded with 467 976 adults successively recruited between 1996 and 2008 (median follow-up 8.5 years) in Taiwan. Fully active was defined as those with 30 min of leisure time physical activity per day for at least 5 days a week. 12 variables were controlled, including medical history, life style and risk factors. High sUA was defined as uric acid above 7.0 mg/dL. Their all-cause mortality was significantly increased. Those who exercised minimally, like 15 minutes a day instead of 30 minutes, in brisk walking instead of jogging, also had reduced nearly all mortality increases from high serum uric acid. High sUA associated with increased mortality is a global phenomenon; up to one-third of individuals have levels of uric acid above 7 mg/dL in some Asian populations, as do one-quarter of Americans.
