• What Causes of Health Disparities
• Disparities can exist due to
There can be disparities due to:
• Biological causes (e.g., one group at higher risk for a disease due to genetics) certain
groups are more likely to have diabetes than other groups and this can be due to the
thrifty gene hypothesis: - this hypothesis explains why certain ethnic groups might
be more likely to develop diabetes given the same diet that most of us consume ex.
You have person from group A and someone from Group B and they both have the
same diet, one person has the health prb of diabetes or CVD and the other doesn't.
the thrifty gene hypothesis can explain part of this - the thrifty gene hypothesis is
that certain ethnicities due to history of famine (Extreme scarcity of food) were
more likely to hold onto sugars and store them into fats, they're much better at
storing sugars and turning them into fat which means they were much better
prepared for times of famine - other groups weren't successful at doing so, it wasn't
adaptive but now it is adaptive in our society but they weren't likely to develop
diabetes
• It could be partly biological but Biology always exists in the context of what we do,
we're people we have attitudes, we have behaviours and our attitudes and behvs
are shaped by our env too - if I didn't know that chocolate cake exists I wouldn't eat
it, sometimes you don't grow up around certain items but learn about them at a
later stage and sometimes they might be healthy sometimes they might not be so
it's shaped by what is available, what we can afford, what we're familiar with etc -
there are biological causes ex. A man cant be susceptible to breast/ovarian cancer so
certain things could be biological but certain things can be psychological too due to
your behvs, your psychological state, the amount of stressors that people
experience, behvs people engage in and social causes due to socio-cultural causes -
it could be knowledge about health and it's determinance; so if people arent aware
that there is a prb, it could be use of or access to health care servcies
• If we want to think about these disparities, we havent done a good job at reducing
these disparities in Canada but there are public health interventions that can help us
reduce some of these disparities
• Psychological causes (e.g., one group at higher risk due to behaviours or
psychological states)
• Social causes (one group at higher risk due to sociocultural differences)
o Knowledge about health its determinants
o Use of health services
o Access to health services
• PH campaigns are there to prevent injuries and prevent behvs ex cigarettes etc
