Evidence from epidemiological studies carried out
in the US shows that a sedentary life-style
increases the incidence of more than 20 chronic
diseases. One such study, a Nurses' Health
Study, concerned 70,000 female nurses aged 40
to 65 years, it was found that, when nurses
walked the equivalent of three or more hours per
week at a brisk pace, they had 30 per cent less
coronary artery disease, ischemic stroke and
type-2 diabetes, as compared to sedentary
nurses. In another study, some site-specific
cancers were found to be also more prevalent
when moderately active females become inactive.
Breast cancer rates rose 25 per cent among the
sedentary in one study, and each one-hour
decrease of recreational physical activity per week
during adolescence was associated with a 3 per
cent increased risk of breast cancer. Indeed,
physical inactivity is now the third leading cause of
death in the US and contributes to the second
leading cause, which is obesity. Physical inactivity
is one of the causes of at least 1 in 8 deaths.
