Physical Activity in Public
Health
COMM 311

Physical Inactivity
• Fourth leading risk factor for
global mortality causing an
estimated 3.2 million deaths
globally.
• Globally, around 31% of adults
aged 15 and over were
insufficiently active in 2008 (men
28% and women 34%).
• In 2008, prevalence of insufficient
physical activity was highest in
the WHO Region of the Americas
and the Eastern Mediterranean
Region
• In all WHO Regions, men were
more active than women, with
the biggest difference in
prevalence between the two
sexes in Eastern Mediterranean.
Physical inactivity is the fourth leading
risk factor for global mortality
• Globally, six percent of deaths are attributed
to physical inactivity. “follows high blood
pressure (13%), tobacco use (9%) and is equal
to high blood glucose (6%)”
• Moreover, physical inactivity is the main
cause for approximately 21–25% of breast and
colon cancers, 27% of diabetes and 30% of
ischaemic heart disease burden.
What is physical activity?
Any bodily movement produced by skeletal muscles
that requires energy expenditure.
Regular physical activity helps
to maintain a healthy body
• Lower rates of:
coronary heart disease,
high blood pressure,
stroke, diabetes, colon
and breast cancer, and
depression;
• Lower risk of falling and
of hip or vertebral
fractures;
• More likely to maintain
their weight.
Concepts!
Physical activity should not be
mistaken for sport
What is Moderate-intensity and
Vigorous- intensity Physical Activity
• Physical activity is any
bodily movement produced
by the skeletal muscles that
uses energy.
• It includes sports, exercise
and other activities such as
playing, walking, doing
household chores or
gardening.
• Intensity refers to the rate at
which the activity is being
performed
• Examples of moderate
physical activity could include:
brisk walking, dancing or
household chores.
• Examples of vigorous physical
activity could be: running, fast
cycling, fast swimming or
moving heavy loads
What does accumulating physical
activity throughout the week mean?
Doing some physical activity is
better than doing none
• The concept of
accumulation refers to
meeting the goal of 60
minutes per day or 150
minutes per week by
performing activities in
multiple shorter bouts
spread throughout the day.
• Inactive adults, older adults
and those with disease
limitations will have added
health benefits when they
become more active.
• They should accumulate
at least 150 minutes of
moderate-intensity
aerobic physical activity
throughout the week or
do at least 75 minutes of
vigorous intensity
aerobic physical activity
throughout the week or
an equivalent
combination of
moderate- and vigorousintensity activity.
• Aerobic activity should
be performed in bouts of
at least 10 minutes
duration.
• Muscle-strengthening
activities should be done
involving major muscle
groups on 2 or more
days a week.
Recommendations for 65 years and above:
Recommendations for 18-64 years old:
Recommendations for 5-17 years old:
• They should
accumulate at least 60
minutes of moderate
to vigorous intensity
physical activity daily.
• Amounts of physical
activity greater than
60 minutes provide
additional health
benefits.
• Most of the daily
physical activity should
be aerobic. Vigorous
intensity activities
should be
incorporated,
including those that
strengthen muscle and
bone, at least 3 times
per week.
• Similar to adults
• Older adults, with
poor mobility, should
perform physical
activity to enhance
balance and prevent
falls on 3 or more
days per week.
• When older adults
cannot do the
recommended
amounts of physical
activity due to health
conditions, they
should be as
physically active as
their abilities and
conditions allow.
THESE RECOMMENDATIONS ARE
RELEVANT TO ALL HEALTHY
ADULTS!
Unless specific medical conditions indicate the contrary, these
recommendations apply to all people, irrespective of gender, race,
ethnicity or income level. They also apply to individuals with chronic
noncommunicable conditions, not related to mobility, such as
hypertension or diabetes. These recommendations can be valid for
adults with disabilities as well.
Supportive environments and communities
may help people to be more physically active
Global Strategy on Diet, Physical
Activity and Health (DPAS)
In May 2004, the 57th
World Health Assembly
(WHA) endorsed the
World Health Organization
(WHO) Global Strategy on
Diet, Physical Activity and
Health. (Resolution
WHA55.23).
DPAS
What is DPAS?
What are the key issues
addressed by the strategy?
• The strategy provides
Member States with a
range of global policy
options to address two of
the major risks responsible
for the heavy and growing
burden of
noncommunicable diseases
(NCDs): unhealthy diet and
physical inactivity.
• The strategy explains the
global burden of NCDs and
how healthier diet,
nutrition and physical
activity can help to prevent
and control them
