A

Variation in
Vb. amount of rings on the neck, disks in their lips
But also clothing across cultures

Universally
Preferences for visual appearances have evolutionary roots
Commonalities across cultures in what is perceived as attractive:
1. Clear complexion
2. Bilateral symmetry
3. Average features
Key factor: Healthy appearance
People are attracted to healthy mates.

Q

Clear complexion

A

Skin signals health more directly than any other visible aspect
The cosmetics industry provides people with ways to make their
complexion look clearer.
=> Skin conditions correlated with stigmmatization (aversive research)

Q

Bilateral symmetry

A

= marker of health
- When an organism develops under ideal conditions its right and
left sides will be symmetrical.
- Genetic mutations, pathogens, or stressors in the womb can lead
to asymmetrical development.
- On average, asymmetrical faces are viewed as less attractive

Q

Average features

A

More attractive than faces that deviate from average.
1. Average features are less likely to contain genetic
abnormalities and are more symmetrical.
2. We can more easily process any kind of stimulus that is closer
to a prototype than one that is further from a prototype.
& Easy processing is associated with a pleasant feeling that gets
interpreted as attractive.

Q

Cultural differences (body)

A

“average is attractive” does not apply to aspects beyond facial features.
- This is seen with people’s weight, height, muscles, breasts, and hips.
- For such aspects, it’s often bodies that depart from average that are seen as more attractive.
- The kinds of body weights that are perceived to be most attractive vary considerably across cultures

Q

Cultural diffrences - Body Weight (Western Africa)

A

Heavier women were universally found to be more attractive.
Western Africa, the term “fat” is often viewed as
complimentary
- ideal woman is overweight
= sign of wealth and fertility, strength and beauty
- slim people are seen as weak or ill
- malnutrition and infection are major causes of death
Undeveloped countries: Thinner tend to be poorer

Q

Cultural diffrences - Body Weight (Western)

A

women who are unusually thin fit the ideal body weight.
- Rich countries: Thinner tend to be richer
- These ideals for thinner women have been more prevalent during
the past few decades, while actual average body weights have
increased

Q

Cultural diffrences - Body Weight (Non-western)

A

People in non-Western cultures and non-Western immigrant groups
adopt deviant Western body images: rise in anorexia and bulimia
E.g. South Africa rising incidence of eating disorders: Zulu
schoolgirls use laxatives and diet pills to ‘look less like their mums
and more like western girls’

Q

Body image and media

A

Media often portray unattainable ideals.Major influence on feelings of inferiority, views on self as being abnormal, not beautiful or even ugly.
Leading to
 use of cosmetics
 braces
 tanning (or whitening) -> increased risks of (skin) cancer
 plastic surgery - > risk of cutting in a healthy body (e.g., risks of
anesthesia, infections)

Q

Propinquity effect

A
  • People are more likely to become friends with people with whom they frequently interact
  • Based on mere-exposure effect: the more we are exposed to a stimulus, the more we are attracted to it (conditioning & easy to process)
  • Culturally universal mechanism

Q

Similarity-attraction effect

A

People are attracted to others if they share many similarities
(e.g., in attitudes, economic background, personality,
religion, activities)
- Particularly strong in cultures with high relational mobility
(individualist > collectivist cultures)

Q

Human biology

A
  1. Innate biological differences
    = result of selection pressures over generations
  2. Acquired biological differences
    = cultural effects on one’s biology in 1 life-time,
    independent of genes

Q

Innate biological variablility

A

Different environments have different selection pressures,
leading different populations to evolve different traits.
=> Most salient example of genetic variability of humans across
different populations = skin color.
Strongly correlates with ultraviolet radiation (UVR)
that reaches different parts of the globe.
=> Light skin allows sufficient UVR to synthesize Vitamin D.
=> Dark skin prevents over-absorption of UVR, and prevents
breakdown of folic acid (Risks of anemia, birth defects, or skin
cancer).
Exception: Inuit (Greenland)
diet rich in fish and sea mammal blubber, high in vitamin D

Q

Innate biological variablity –Culture-gene coevolution

A

as culture evolves,
it places new selection pressures on the genome, which also evolves in response to those pressures.
1: Cow domestication: lactase persistence
Culture-gene coevolution can be quite indirect
2: Farming yams in West Africa:

Q

Acquired Biological Variability - Visual acuity

A

affected by cultural practices within a life-time.
children swim underwater to retrieve seafood ->
 twice the underwater visual acuity as European children.
 This is not a genetic adaptation —
European children can do the same through training.

Q

French paradox of obesity

A

French still eat significantly less calories a day than Americans.
 Portion sizes
 People eat what’s given to them, portioned.
 Indeed, in comparison to portion sizes in the France:
 USA yogurt containers are 80% larger.
 McDonald’s serves 70% more fries in the United States per container
 Portion size has been continuously increasing in USA
 Attitudes toward food
 French savor their food more than Americans.
 Americans have more conflicting attitudes

Q

Acquired Biological Variability - Height

A

 Economic wealth of a country has close ties with the height of its
people.
 More wealth brings healthier diet (more vitamins and nutrients),
especially at ages when growth spurts occur.
 Fluctuations of countries’ heights across time have coincided with
broad societal changes that have an impact on diet.

22
Q

Acquired Biological Variability - Age

A

Influenced by a number of factors, such as
1. Social and economic development (poverty in many African
countries, Monaco is incredibly wealthy)
2. Birth rates
3. Disease
4. Ongoing conflict

23
Q

Health behaviour

A

Cultural differences in life-style and health-behavior are
associated with health

24
Q

Health behavior - Diet

A

What remarkable cultural differences in eating (diet, rituals … )
that might influence health did you observe?

25
SES and Health
Associated with health via several psychosocial variables :
25
SES and Health
Associated with health via several psychosocial variables : -Access to adequate health care - Attitudes towards and occurrence of unhealthy habits - Risky jobs - Personality characteristics  Sense of hostility and pessimism, likely due to lower school achievement in low-SES environments (which bars people from employment opportunities), leads to poorer health. - Cognitive resources - Stress - Control - Perceived wealth - Ethnicity
26
SES and stress
(Chronic) stress can affect health in multiple ways, including: 1. Stress leads people to engage in unhealthy habits. 2. Stress weakens the immune system. 3. Higher blood pressure & risk cardiovascular disease
27
Role of control with SES and Health
(perceived) Low and High economic status with (feelings of) high control results in good health. Control is the mediator in this case
28
Education and life expectancy
The higher education the higher the average (health) life expextancy.
29
Subjective wealth
subjective perceptions of wealth are predictive of health:  A sense of relative deprivation may lead to stress  It is not how poor one is but rather how poor one feels that affects health. Particularly problematic in societies where there is great social inequality (which is increasing in many countries)
30
Ethnicity
Is also a factor implicated in the link between SES and health  In the United States, African Americans and Hispanic Americans have been studied extensively in terms of their health outcomes compared to European Americans.
31
Ethnicity, genetics vs. discrimination and health
Prevalence rates for African Americans exceed those of European Americans, particularly for hypertension and heart disease might often be attributed to SES. This particularly affects highly educated African American men – contrary to what one might expect based on research on SES and health outcomes. Genetics? Hypertension rates are actually much higher for African Americans compared to West Africans (who have comparable rates to European Americans) Discrimination, racism -> stress, puts people at greater risk for hypertension, especially those with high aspirations to achieve.
32
Epidemiological paradox
Hispanic Americans tend to have better health outcomes on average compared to European Americans, although they are generally of a lower SES. One explanation is that Hispanic Americans engage in healthier behaviors than European Americans: 1. Drinking and smoking less 2. More social support from large communities 3. High level of positive affect is a cultural norm
33
Immigrant minority groups and health
Immigrants EU:  Lower self-perceived health (even after controlling for age, gender, and SES).  Social, cultural, and economic factors explain partially  Visits GP 30% higher, often for the same issue.  Physiotherapy and prescribed drug use higher  Use of specialist / hospital little higher But, even more health issues than health care use! (health issues 22% higher, health care use 15%)
34
Religion and health
Something so meaningful to a large number of people might also be good for their health. =>an emphasis on caring for the physical, body as a “Temple of the Holy Spirit”. Religion might positively affect physical health by 1. Encouraging healthy behavior, such as no smoking, hence also less smoking 2. Increasing social support 3. Reducing stress and negative emotions

Religion might positively affect physical health by 1. Encouraging healthy behavior, such as no smoking, hence also less smoking 2. Increasing social support 3. Reducing stress and negative emotions
35
Religion health outcomes
Impact on a host of physical diseases and the response of those diseases to treatment. Indeed, relation between religious and spiritual involvement and e.g.,: 1. Lower prevalence coronary heart disease 2. Lower blood pressure 3. Better immune function 4. Better endocrine function Moreover, often people turn to religion to cope with illness
36
Negative effects of religion
Although religious people tend to have healthier diet, they also tend to eat more  Might refrain from vaccination (e.g., measles)  Refrain from (timely) using life-saving medication or other interventions
37
Health behavior and sleep
Current guidelines suggest around 7-9 hours a night  Before electric lighting, people’s sleeping cycle had two phases.  First, people went to sleep for a few hours a little after sunset.  They woke up in the middle of the night, during which they engaged in some leisurely activities.  Then they slept for a few hours again until around dawn  Siesta, sleeping at the heat of the day
38
Very concept of health differs across cultures
From a western point of view, health is often conceptualized in a biomedical model, where health is seen in terms of (the absence of) disease.  Disease in turn is seen as originating from a specific and identifiable cause within, or arriving from outside, the body.  Views from other cultures regard health as an imbalance between  negative (yin) and positive (yang) forces in Chinese medicine,  or elemental ingredients (bhutas) and waste products from food (vayu, pitta and kaph) in Indian Ayurvedic medicine.  Alternative common view: diseases are due to supernatural causes, such as witches, demons, or ghosts.
39
How the body functions - Western
In France, the metaphor of the body is the “terrain”, which emphasizes a sense of balance.  French doctors prescribe more long rests and spa visits.  Use of tonics and vitamins to strengthen immune system  Dirt and germs can strengthen one’s terrain; thus, there is less emphasis on daily bathing.
40
How the body functions - USA
the body is a machine, threatened by external factors  American doctors are more likely to do surgery (to fix malfunctioning parts).  Germs are key threat to health  Doctors prescribe more antibiotics than anywhere else
41
Views of health are shaped by culture
These distinctions might seem clear-cut, but people can simultaneously hold views grounded in different traditions.  A patient might seek out traditional care for 1 type of complaint while seeking biomedical care for another complaint, or both simultaneously.  For example:  Yoga in West  Rise use Western medicine in Eastern cultures  Documentary de Outsiders on healthcare
42
Chirindi in Zimbabwe (story)
Woman is coughing & Telegrams husband to come  Anthropologist Jacobson-Widding asks “Why not hospital?”  Woman was shocked; a doctor? Only husband could help.  She just had a miscarriage -> hot condition  Husband was in military service in the capital, you know what men will do then …  Now that cough, chirindi.  His escapades would only worsen her hot condition  He had to come home immediately to sleep with her and lower the heat  Otherwise she might die
43
Culture specific condition - menopause
Diagnosis does not exist in Asian cultures  Prevalence of individual symptoms also much lower in Japan  Women who see menopause as a medical condition rate it significantly more negatively than those who view it as a life transition or a symbol of aging.  We can interpret the same sensations and experiences in different ways depending on culture, leading to different diagnoses and treatments
44
Culturally different experiences of pain
Ethnic/ racial group differences in experimental pain perception  African Americans consistently show lower pain tolerance and often lower pain threshold than non-Hispanic whites  May be influenced by  Genetic differences  Methodological factors (e.g., biased sampling)  Language issues  Life-experiences
45
Opioid crisis
Increase prescription opioid oxycodone from 2.8% in 2010 to 14.2% in 2017.  Opioid crisis in USA (130 deaths a day, 2.1 million w opioid use disorder), also increasing in Nl.  Possible reasons, 1. Changing views on pain – not wanting to accept pain as part of life 2. Pharmaceutics industry (downplay risks, aggressive marketing) 3. Misperception of addictiveness 4. Hospital quality judged based on pain scores
46
Wait and see attitude
Dutch view:  Patients wait before they call upon doctor  Doctors are reluctant to prescribe medication or refer to specialist  GP is gatekeeper: refers further, or not In, for example, Greece, one will contact doctor much more quickly, directly at the hospital, and receive medication, including antibiotics.  Also in USA many more medications available over the counter
47
Placebo effects and culture
Improvement rates upon placebo use  Brazil 7%  Denmark & Netherlands 22%  Germany 59% Unclear what explains these differences To complicate matters: placebo effect for lowering blood pressure was lowest in Germany of 32 countries examined. So cultural differences can be specific to different conditions
