Q

Nutrition Transition

A

The shifts in the way we eat and move & subsequent effects on our body composition over the history of man
In the last 20–30 years, the world has reduced its water intake, shifted towards sugar-sweetened beverages, increased its proportion of food that is sweetened and ultra processed and reduced its intake of many health
components of our diet, including legumes, fruits and vegetables

A 
Rapid shifts in dietary, activity & body composition
 Obesity trends
 Dietary changes
 Physical activities
 Rapid social changes:
• Urbanization
• Globalization of Mass Media
20
Q

Nutrition Transition in developing countries

Dietary changes: shifts in the overall structure over time

A

The diets of the developing world: shifting rapidly
Traditional, low cost diet, rich in fiber & grain:
replaced by high-cost diets include greater
proportions of sugars, oils, & animal fats.
Results: obesity & associated chronic diseases

21
Q

The joint presence of under-nutrition and over-weight

A

Poor people are malnourished because they do
not have enough to feed themselves, & they
are obese because they eat poorly (Aguirre)

22
Q

Nutrition Transition In developing countries

The politics are different in developing world (dilemma !)

A

The capacity to address the rapid increase in NR-NCDs does not exist
 Politicians have focused on hunger (malnutrition) & infectious
diseases (AIDS,TB, New Viral diseases such as Ebola)
 The NR-NCDs are increasing in prevalence more rapidly
Medical systems have not enough time to adjust to
the needs
Public health systems are not able to begin
addressing the situation

23
Q 
The nutrition transition to 2030
11/23/2016 41
Schmidhuber & Shetty, 2005
Why developing countries are likely to bear the major
burden?
A

Population growth to slow
Urbanization to accelerate
Rapid income growth globally, but with considerable regional
differences
Economic disasters, (2008),
Radical change in the food marketing and distribution system.
Ageing populations & ‘‘little emperors’’
Foetal Programming ‘‘The thrifty phenotype’’
Childhood undernutrition, stunting and central obesity
Ethnic differences in disease risk: Interactions of genetic
predisposition and environmental change
Infections and chronic disease (if you survive malnutrition and disease are most likely to get chronic diseases when your old

24
Q

Dietary Acculturation

A

Immigration at a young age makes children more likely to
assimilate to a new culture

Q

Health issues among immigrants

A

• Declines in self‐assessed physical and mental
health are observed amongst immigrants in as little as two years after arrival
• Within 4 years after arrival, the proportion of
immigrants reporting fair or poor health almost
triple.
• Objective measurements show declining health
among immigrants after arrival (e.g. chronic
conditions, prevalence obesity)

31

– Lifestyle changes
• Nutrition, Over /Under, Nutrient deficiencies
• Less physical activity

32
Q

Health issues…, overweight & obesity

A

• The prevalence of overweight & obesity: higher among
long‐term (11 yrs or more) than more recent immigrants
• Obesity rates have been shown to increase in refugee
children with the length of time following resettlement.
• The increase in rate of overweight & obesity, may result
from transition away from cultural diets & lifestyle
pattern to a more “western” diet & sedentary lifestyle
(Nutrition Transition)
• Men not women

Health issues…, overweight & obesity
Tremblay MS et al. 2005 BMC Public Health. 2013 May 10;13:458. doi: 10.11

33
Q

Health issues…, overweight & obesity

A 
• Factors that affect obesity
– age,
• younger age are more likely to assimilate the new culture vs. older age

• Immigrants have lower rates of heart disease mortality than the
Canadian‐born population
• Risk factors:
– obesity,
– hyperlipidemia,
– hypertension,
• Exposure to fast foods, high in sodium
associated with acculturation
• Immigrants are hesitant to be screened for CVD as they are fearful of
finding they have a disease which means they will also not get treatment
for such diseases
• Rates of heart disease were reportedly high among South Asian
immigrants

35
Q

Health issues…, diabetes

A

• South Asians are the fastest growing immigrant population in
Canada
• They also develop diabetes up to ten years earlier, and at a
lower BMI than Caucasians in Canada, the US and the UK
– genetic predisposition,
– insulin resistance,
– higher levels of visceral/abdominal adipose tissue,
– traditional diets high in fats and sugars
• South Asians: receive inadequate treatment

A

• Immigrants’ cancer rates shifted toward rates of the host
population.
• Breast cancer mortality rates from rare in home country to the rate in
native population (Canada and Australia)
• Dramatic increase in cancer risk among second‐ and third‐
generation Japanese
• Acculturation explains the findings from generational studies
demonstrating increases in cancer rates among the offspring of
migrants and subsequent generations
• Inadequate screening of cervical cancer
• Cultural, linguistic & systemic barriers to cancer prevention,
screening and treatment programs have been identified for
immigrant populations, particularly newcomers

38

A

After an initial risk period, immigrant mental health improved
over time and often persisted into the second generation.
• Certain sub‐groups experienced an increased
mental health risk following migration.
– Refugees
• experienced traumatic events such as war, famine and forced
migration are at an increased risk of mental health problems, such
as lasting depression, PTSD and suicide
– Seniors
– Women
• high rate of depression among women of four ethnic groups
(Chinese, Vietnamese, Portuguese & Latin American

40
Q

Perinatal Health

A

No evidence that immigrant women &
children experience worse health outcomes
than their Canadian‐born counterparts,
– exception of refugee women
• Immigrants, especially newcomers, were more
likely to experience barriers to preventive
services (e.g. immunization and prenatal care)

• There is no one recipe for all when providing services to newcomers

43
Q

why is health canada data so different

A

exclude all people who cant speak english or french. dont seperate refugee and immigrant
