Unit#1 health and disease

  1. Post RN BScN 2nd Semester UNIT I: HEALTH AND ILLNESS A SOCIO-CULTURAL PERSPECTIVE Saima Victor Post RN BScN
  2. Objectives At the end of the unit learners will be able to:  Explain the concept of culture  Discuss the importance of socio cultural anthropology and its relation to health  Explain the concept of society at micro and macro levels  Describe the concepts of health, illness and disease, society, community, culture,  Discuss health and disease as a product of social behaviour
  3. Culture  Culture refers to the cumulative deposit of knowledge, experience, beliefs, values, attitudes, meanings, hierarchies, religion, notions of time, roles, spatial relations, concepts of the universe, and material objects and possessions acquired by a group of people in the course of generations through individual and groups.  Culture is the systems of knowledge shared by a relatively large group of people.  Culture is the sum of total of the learned behavior of a group of people that are generally considered to be the tradition of that people and are transmitted from generation to generation.
  4.  The position that the ideas, meanings, beliefs and values people learn as members of society determines human nature. People are what they learn. Optimistic version of cultural determinism place no limits on the abilities of human beings to do or to be whatever they want. Some anthropologists suggest that there is no universal "right way" of being human. "Right way" is almost always "our way"; that "our way" in one society almost never corresponds to "our way" in any other society. CULTURAL DETERMINISM
  5.  Ethnocentrism is the belief that one's own culture is superior to that of other cultures. It is a form of reductionism that reduces the "other way" of life to a distorted version of one's own. This is particularly important in case of global dealings when a company or an individual is imbued with the idea that methods, materials, or ideas that worked in the home country will also work abroad. CULTURAL ETHNOCENTRISM
  6.  Different cultural groups think, feel, and act differently. There is no scientific standards for considering one group as intrinsically superior or inferior to another. Studying differences in culture among groups and societies presupposes a position of cultural relativism. It does not imply normalcy for oneself, nor for one's society. It, however, calls for judgment when dealing with groups or societies different from one's own. Information about the nature of cultural differences between societies, their roots, and their consequences should precede judgment and action. Negotiation is more likely to succeed when the parties concerned understand the reasons for the differences in viewpoints. CULTURAL RELATIVISM
  7.  1- Symbols are words, gestures, pictures, or objects that carry a particular meaning which is only recognized by those who share a particular culture. New symbols easily develop, old ones disappear. Symbols from one particular group are regularly copied by others. This is why symbols represent the outermost layer of a culture.  2- Heroes are persons, past or present, real or fictitious, who possess characteristics that are highly prized in a culture. They also serve as models for behavior. MANIFESTATIONS OF CULTURE
  8. Cont..  3- Rituals are collective activities, sometimes superfluous in reaching desired objectives, but are considered as socially essential. They are therefore carried out most of the times for their own sake (ways of greetings, paying respect to others, religious and social ceremonies, etc.).  4-The core of a culture is formed by values. They are broad tendencies for preferences of certain state of affairs to others (good-evil, right-wrong, natural- unnatural).  Symbols, heroes, and rituals are the tangible or visual aspects of the practices of a culture. The true cultural meaning of the practices is intangible; this is revealed only when the practices are interpreted by the insiders.
  9.  People even within the same culture carry several layers of mental programming within themselves. Different layers of culture exist at the following levels:  The national level: Associated with the nation as a whole.  The regional level: Associated with ethnic, linguistic, or religious differences that exist within a nation.  The gender level: Associated with gender differences (female vs. male)  The generation level: Associated with the differences between grandparents and parents, parents and children. LAYERS OF CULTURE
  10.  The social class level: Associated with educational opportunities and differences in occupation.  The corporate level: Associated with the particular culture of an organization. Applicable to those who are employed.
  11. Cultural differences  Cultural differences are the various beliefs, behaviors, languages, practices and expressions considered unique to members of a specific ethnicity, race or national origin. ... While these various differences can create a more vibrant office, they can also lead to more than a few problems resulting from culture clash.  Cultural diversity is the quality of diverse or different cultures, as opposed to monoculture, the global monoculture, or a homogenization of cultures, akin to cultural evolution. The phrase cultural diversity can also refer to having different cultures respect each other's differences
  12. Culture shock  Culture shock is a sense of anxiety, depression, or confusion that results from being cut off from your familiar culture, environment, and norms when living in a foreign country or society. Those experiencing culture shock go through distinct phases of euphoria, discomfort, adjustment, and acceptance.
  13. community  A community is a social unit with commonality such as norms, religion, values, customs, or identity. Communities may share a sense of place situated in a given geographical area or in virtual space through communication platforms.  The two main types of communities are  1-Major which are self-sustaining and self-regulating (such as a forest or a lake)  2-Minor communities which rely on other communities (like fungi decomposing a log) and are the building blocks of major communities.
  14. Community identity  Community identity is based on birth and belonging rather than on some forms of acquired qualifications or accomplishments. These kinds of identities are called ascriptive i.e. they are determined by birth and individual's choice is not involved.  A good community is a cohesive, safe, confident, prosperous and happy place. It is free of poverty and crime, providing a high quality of life for everyone that lives there. It values and promotes open, participative development processes underpinned by a continuous culture of trans-generational learning.
  15. Community development and functions  Community development is a holistic approach grounded in principles of empowerment, human rights, inclusion, social justice, self-determination and collective action (Kenny, 2007).  The community has five functions: 1-production-distribution-consumption: The community provides its members with the means to make a living. This may be agriculture, industry, or services.
  16. 2- socialization The community has means by which it instills its norms and values in its members. This may be tradition, modeling, and/or formal education. 3-social control The community has the means to enforce adherence to community values. This may be group pressure to conform and/or formal laws. 4- social participation The community fulfills the need for companionship. This may occur in a neighborhood, church, business, or other group. 5- mutual support The community enables its members to cooperate to accomplish tasks too large or too urgent to be handled by a single person. Supporting a community hospital with tax dollars and donations is an example of people cooperating to accomplish the task of health care.
  17. Anthropology  The study of human societies and cultures and their development.  The study of human biological and physiological characteristics and their evolution.  The Four Subfields  Archaeology. Archaeologists study human culture by analyzing the objects people have made. ...  Biological Anthropology. ...  Cultural Anthropology. ...  Linguistic Anthropology.
  18. Cultural Anthropology  the branch of anthropology concerned with the study of human societies and cultures and their development.  Sociocultural anthropology is the study of human similarities and differences and their impact on a wide range of social phenomena. ... Through a range of research methods anthropologists analyze what unites diverse peoples as well as what distinguishes them from one another.  Sociocultural anthropologists focus on the study of society and culture, while often interested in cultural diversity and universalism. Additionally, sociocultural anthropology is often split into social anthropology and cultural anthropology. ... Linguistic Anthropology.
  19. Medical Anthropology  Medical Anthropology is a subfield of anthropology that draws upon social, cultural, biological, and linguistic anthropology to better understand those factors which influence health and well being (broadly defined), the experience and distribution of illness, the prevention and treatment of sickness, healing processes ..
  20. Role of Anthropology in understanding health and disease  Medical Anthropology is a subfield of anthropology that draws upon social, cultural, biological, and linguistic anthropology to better understand those factors which influence health and well being (broadly defined), the experience and distribution of illness, the prevention and treatment of sickness, healing processes ... The sociology of health and illness covers sociological pathology (causes of disease and illness), reasons for seeking particular types of medical aid, and patient compliance or noncompliance with medical regimes. Health, or lack of health, was once merely attributed to biological or natural conditions.
  21. Society  A society is a group of individuals involved in persistent social interaction, or a large social group sharing the same spatial or social territory, typically subject to the same political authority and dominant cultural expectations.  Two primary components of a society are its culture and its social structure. Society is one of the basic sociological terms. In simple sense, society is a large grouping that shares the same geographical territory, shares a common culture and social structure, and expected to abide by the some law  Macro-level sociology looks at large-scale social processes, such as social stability and change. Micro-level sociology looks at small-scale interactions between individuals, such as conversation or group dynamics.
  22. Health  Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. The enjoyment of the highest attainable standard of health is one of the fundamental rights of every human being without distinction of race, religion, political belief, economic or social condition.  There are five main aspects of personal health: physical, emotional, social, spiritual, and intellectual.
  23. Illness 1: an unhealthy condition of the body or mind Germs can cause illness. 2 : a specific sickness or disease Colds are a common illness. illness.  Examples of chronic illnesses are: Alzheimer disease and dementia. Arthritis. Asthma. Cancer. COPD. Crohn disease. Cystic fibrosis. Diabetes.
  24. Disease  Disease, any harmful deviation from the normal structural or functional state of an organism, generally associated with certain signs and symptoms and differing in nature from physical injury. A diseased organism commonly exhibits signs or symptoms indicative of its abnormal state.
  25. Bio behavioral Factors in Health and Disease  Relationships between behavior and health has been aided by technology and by conceptual advances in the behavioral, biological, and medical sciences. Our understanding of the interactions between brain function and behavior has been enriched by advances in behavioral neurobiology, neuroscience, and neuroendocrinology from molecular mechanisms to psychological systems.
  26. STRESS, HEALTH, AND DISEASE  The Stress Response  the study of stress has provided a major link in explaining the behavioral variables and the biological factors that influence physical health. Stress both causes and modulates a diversity of physiological effects that can enhance resistance to disease or cause damage and thereby promote disease. For example, stress-related hormones, such as cortisol and epinephrine, have protective and adaptive functions as well as damaging effects.  https://www.ncbi.nlm.nih.gov/books/NBK43737/
  27. Homeostasis  Individual behavior is important because it increases or decreases the pathophysiological cost of stress through diet, exercise, and other activities.  The stress response is an important component of the body's regulatory systems. The maintenance of constant and appropriate internal conditions and functioning in the face of changing environmental demands is called homeostasis, an idea first developed by Walter Cannon (1936). The stress response, however, primarily involves reaction in an emergency.
  28. Allostasis and Allostatic Load  An important new attempt to understand the relationships between environmental and behavioral challenges and stressors, the physiological responses to these events, and disease uses the terms allostasis and allostatic load. Allostasis is the maintenance of overall stability (homeostasis) through the constant adjustment and balancing of various components in the process of adapting to challenge. Sterling and Eyer (1988)  Allostatic load is the wear and tear the body experiences as a result of repeated allostatic response (McEwen, 1998; McEwen and Stellar, 1993).
  29. Protective and Damaging Effects of Stress Mediators  A behavioral response to challenge or stress can be protective or damaging. The risk of harm or disease can be increased by such patterns of behavior as hostility or aggression, and it can be reduced by cooperation and conciliation. Cigarette-smoking, excessive alcohol consumption, high fat consumption, and exposure to physical hazards increase the risk, as does insufficient physical activity. The link of allostasis and allostatic load can be applied to various behavioral responses (Perseghin et al.,1996)
  30.  The mediators of protective and damaging effects of allostatic responses are mainly adrenal steroids and catecholamines. Other hormones—such as dehydroepiandrosterone, prolactin, growth hormones, and the cytokines—also mediate adaptive or maladaptive effects, but their consequences are often specific to an organ or a system. Once the mediators are released, they produce their effects by acting on cellular receptors. The effects can be classified as primary effects; secondary outcomes, which are risk factors for disease; and tertiary outcomes, which are diseases themselves (McEwen and Seeman, 1999
  31. Neurotransmitters, Experience, and Behavior  Changes in balance among neurotransmitters in the brain can influence behavioral responses to potentially stressful situations, can alter the interpretation of stimuli, and might be associated with anxiety and depression.  Serotonin is a neurotransmitter with widespread influences throughout the brain. The serotonin system exerts widespread influence over mood and mood disorders, such emotional responses as hostility and aggression, arousal, sensory perception, and higher cognitive functions. For example, low concentrations of brain serotonin are associated with increased incidence of suicide (Brown et al., 1982; Mann, 1998), impulsive aggression (Brown et al., 1982; Higley et al., 1996a, 1996b), and the abuse of alcohol and other substances (Higley et al., 1991).
  32. Neural and Endocrine Effects on the Immune System  Many chemical messengers of the nervous and endocrine systems are immunomodulatory, and these substances are important in regulating inflammatory and immune responses (Felten et al., 1987).
  33. Stress and Immune System Function  The recognition of the importance of bidirectional communication between neural, endocrine, and immune systems through shared ligands and receptors led to a major research emphasis on immunoregulation by hormones, peptide neuromodulators, and neurotransmitters.  The primary function of the immune system is to protect the host from infectious and malignant challenges. Acute stress enhances immune function, and it does so in part by promoting immune cell translocation to sites of immune challenge (Dhabhar et al., 1995, 1996), whereas chronic stress has the opposite effect: it impairs immune function (Dhabhar and McEwen, 1999; Hermann et al., 1995).
  34. Cont….  Various aspects of immune function in states of stress- induced neuroendocrine activation, with a primary emphasis on negative, immunosuppressive outcomes, have been reported (Dobbs et al., 1993; Kiecolt-Glaser et al., 1996).
  35. Behavioral and Psychosocial Factors  Psychosocial factors can influence the course of chronic human disease along several pathways. Behavior that has perceived short-term benefits, such as mood-enhancement induced by cigarette-smoking or excessive alcohol consumption, but that causes long-term injury constitutes one.  Another involves the influence of social and environmental factors, such as socioeconomic status or stress on disease processes.  A third consists of individual psychological factors, such as hostility and depression, that interact with the other two pathways to increase susceptibility to illness.
  36. Anger  Anger is a psychological state thought to be related to hostility. Expression of anger has been shown to trigger myocardial infarction. In a study of patients undergoing coronary angiography, recall of anger was a potent stimulus that induced vasoconstriction in diseased coronary arteries, but not in healthy arteries (Boltwood et al., 1993). The recall of anger can also produce an acute impairment in ventricular function in patients with CHD (Ironson et al., 1992.
  37. Hostility  Hostility is the psychosocial variable most often associated with the incidence of CHD (Booth-Kewley and Friedman, 1987). In the context of physical health, hostility is defined usually as a stable attribute characterized by mistrusting cynicism that leads to antagonistic or aggressive behavior and feelings of anger (Miller et al., 1996)
  38. Depression  Depression affects about half of patients who experience myocardial infarction. Depression predicts significantly poorer outcome with heart disease (Denollet et al., 1996; Denollet and Brutsaert, 1998; King, 1997) and roughly doubles the risk of recurrent cardiovascular events (Barefoot et al., 1996; Barefoot and Schroll, 1996.
  39. Summary  Depression often gets worse if it isn't treated, resulting in emotional, behavioral and health problems that affect every area of your life. Examples of complications associated with depression include: Excess weight or obesity, which can lead to heart disease and diabetes. Pain or physical illness.  Some examples of chronic illnesses that may cause depression are diabetes, heart disease, arthritis, kidney disease, HIV and AIDS, lupus, and multiple sclerosis (MS). Hypothyroidism may also lead to depressed feelings.  Epidemiological data indicate that depression is a significant risk factor for the development of symptomatic IHD in otherwise healthy people, exerting an effect independent of previously established cardiovascular risk factors including sex, weight, activity, blood pressure, and smoking.
