biological determinants of health
Biological factors that determine health may be classified as either endogenous or exogenous.
endogenous
Include genetic heritage and immunity that is passively acquired from maternal antibodies passed across the placenta or transmitted in maternal milk. Genetic heritage is determined largely by responses to biological and physical environmental challenges to which human ancestors were exposed.
exogenous
Exogenous biological determinants of health are the other living things with which humans interact. The most important are microorganisms; also significant are larger organisms that carry them.

Sociopolitical determinants of health
...
social determinants of health
are the conditions in which people are born, grow, live, work and age, including the health system. These circumstances are shaped by the distribution of money, power and resources at global, national and local levels. The social determinants of health are mostly responsible for health inequities - the unfair and avoidable differences in health status seen within and between countries.
todays family unit
-family structures are diverse
-family of origin impacts child's psychological, social and spiritual development
risk factors: housing
-Housing insecurity is linked to income insecurity which in turn leads to illness and premature death.
-
how do politics fit in with social determinants of health?
Social policy:
-min wage
-social assistance
-education
-medicare
-taxes
-canadian pension plan
violence in Canada

violence and health
• To understand and respond to violence, greater emphasis is needed on physical, social, and economic life conditions that will reduce it
• Violence is a barrier to health and a consequence of an unhealthy environment
environmental determinants
The physical environment is an important determinant of health. At certain levels of exposure, contaminants in our air, water, food and soil can cause a variety of adverse health effects, including cancer, birth defects, respiratory illness and gastrointestinal ailments.
primary environmental determinants
-Biological agents in the air, water, and soil

-According to the WHO, over 1 billion people are unable to meet their basic needs (food, water, shelter) because they lack income
components of the environment
PHYSICAL: air, water, soil, housing, climate, geography, heat, light, noise, debris, radiation, etc.

BIOLOGICAL: man, viruses, microbial agents, insects, rodents, animals and plants, etc.

PSYCHOSOCIAL: cultural values, customs, beliefs, habits, attitudes, morals, religion, education, lifestyles, community life, health services, social and political organization.
infectious vs chronic disease
INFECTIOUS
-Short term
-Acute exposure
-May cause epidemic
CHRONIC DISEASE
-Long term
-Low dose exposure
-May alter genes (passing on defective genes to offspring)
overpopulation:
-Effective management of the environment is needed to avoid at least 25% of all preventable diseases worldwide
-13 million deaths could be prevented annually if the environment were healthier
-Unsafe water and air pollution causes 4 million deaths annually in children under 5
-Promoting safe household water storage, better hygiene, and cleaner and safer fuels would reduce disease and death
-Thousands of Canadians are changing their habits and working to improve the environment
-Majority of population growth occurs in developing world
-Estimates for population growth depend on fertility rates and life expectancy
-As the world's population increases so does competition for the earth's resources
-North Americans consume more energy and raw materials per person than any other region of the world
4 types of pollution
-Air
-Water
-Noise
-Land
sources of air pollution
• Sulphur Dioxide
• Particulates
• Carbon Monoxide
• Nitrogen Dioxide
• Ozone
• Lead
• Hydrocarbons
air pollution: photochemical smog
• Brown, hazy mix of particulates and gases
• Sometimes called ozone pollution
• Often occurs in areas of temperature inversion - layer of cool air trapped under a layer of warm air
• May result in: difficulty breathing, burning eyes, headaches, and nausea
• Long term: may cause serious effects, especially among vulnerable people

holistic concept of health
This concept recognizes the strength of social, economic, political and environmental influences on health
concept of disease
-Disease result from complex interaction between man, an agent and the environment.
-From ecological point of view disease is defined as "maladjustment of the human organism to the environment".
the epidemiological triangle
3 vertices:
-"agent" or microbe that causes the disease
-"host" or organism harbouring the disease
-"environment", or external factors that cause or allow disease transmission
biological hazards
-These are living organisms or their products that are harmful to humans.
a) water born diseases
b) food born diseases
c) vector born diseases
a) water borne diseases
1. Examples are polio virus, hepatitis A virus, Salmonella, Shigella, cholera, amoebic dysentery, Giardia, and Cryptosporidium.
2. These disease organisms are shed into the water in feces, and can produce illness in those who consume untreated, contaminated water.
3. Our municipal water treatment facilities are usually able to purify water by removing these agents or killing them by disinfecting the water.
b) food borne diseases
1. Examples of food-borne agents are the bacteria Salmonella, serotype enteritidis, Escherichia coli 0157:H7, as well as other agents.
2. To protect against food-borne diseases, sanitarians from local health departments routinely inspect food service establishments (restaurants) and retail food outlets (supermarkets) to verify that food is being stored and handled properly.
c) vector borne disease
-are those transmitted by insects or other arthropods
1. Examples are St. Louis encephalitis and La Crosse encephalitis transmitted by mosquitoes and plague and murine typhus transmitted by fleas.
2. Improper environmental management can cause vector-borne disease outbreaks.
chemical hazards: pesticides
-result from mismanagement or misuse of chemicals resulting in an unacceptable risk to human health
A. Pesticides are chemicals that have been manufactured for the purpose of reducing populations of undesirable organisms (pests)
1. Examples of categories of pesticides are herbicides and insecticides.
2. Most pesticides kill non-target organisms as well as the target, or pest species.
3. The wise use of pesticides can protect human health and agricultural crops.
chemical hazard: environmental tobacco smoke
is an environmental hazard produced by millions that smoke
1. Diseases associated with ETS include lung cancer and perhaps heart disease.
2. ETS contains 4, 000 substances.
3. The EPA has classified ETS as a Class A carcinogen.
4. Smoking has been increasingly restricted from public buildings and from many private work sites.
5. Regulation of smoking seems to be the best approach to controlling this pollutant
chemical hazard: lead
is a naturally occurring element that is used in the manufacturing of many industrial and domestic products
1. Health problems associated with the over exposure to lead are anemia, birth defects, bone damage, neurological damage, kidney damage, and others.
2. Exposure is by ingestion and inhalation.
3. Children are particularly at risk from eating peeling lead paint.
4. The prevalence of very high blood lead levels among young children declined significantly between 1984 and 1994 primarily because the removal of lead from gasoline.
5. Occupational exposure is a major source of lead intake for adults.
physical hazards
-include airborne particles, humidity, equipment design and radiation
-Radon contamination results from over exposure to radon gas.
1. Radon gas arises naturally from the earth and sometimes occurs at dangerous levels in buildings and homes
2. Breathing in radon gas can cause lung cancer.
3. Homes can be tested for the presence of radon gas for $20.
psychological hazards
-are environmental factors that produce psychological changes expressed as stress, depression, hysteria.

-When environmental resources can support no further growth, the population has reached the equilibrium phase and the environment is said to be at its carrying capacity
sociological hazards
-are those that result from living in a society where one experiences noise, lack of privacy and overcrowding.
-Population growth may be a sociological hazard.
site and location hazards
-Natural disasters are geographical and meteorological events of such magnitude and proximity to communities that they produce significant damage and injuries.
1. Examples are cyclones, earthquakes, floods, hurricanes, tornadoes, typhoons, and volcanic eruptions.
2. The magnitude of devastation of these events can sometimes be great.
3. Biological, psychological and sociological hazards may increase following a natural disaster.
connection!
In the built environment, factors related to housing, indoor air quality, and the design of communities and transportation systems can significantly influence our physical and psychological well-being.

Under-nutrition (increased susceptibility to infectious diseases) and over-nutrition responsible for cardiovascular diseases, cancers, obesity etc.
The Organisation and Function of Health Systems
-A health system comprises all organizations, institutions and resources devoted to producing actions whose primary intent is to improve health

-Most national health systems consist:
public, private, traditional, and informal sectors.
cholera
-Entry: oral
-Colonization: small intestine
-Symptoms: nausea, diarrhea, cramps, vomiting (digestive problems) associated with dehydration
-Face, feet, hands shriveled and turned blue; died in less than a day
-Index case is the point source, first person to become ill -woman soaked diapers in pail and empties pail into cistern pump
-John snow: identified cholera
psychosocial health
Encompasses the mental, emotional, social, and spiritual dimensions of health
people who are psychosocially healthy:
• Feel good about themselves
• Feel comfortable with other people
• Control tension and anxiety
• Meet the demands of life
• Choose a positive outlook
• Enrich the lives of others
• Cherish things that make them smile
• Value diversity
• Appreciate and respect nature
mental health
-The Thinking You
• Rational part of psychosocial health. The ability to:
-perceive things realistically
-use reasoning in problem solving
-interpret what is happening accurately
-evaluate situations effectively and react appropriately
• Sharp declines in rational thinking may indicate poor mental health
emotional health
-The Feeling You
• Subjective side of psychosocial health encompassing physiological arousal, feelings, cognitive processes, and behavioural reactions.
Ability to:
-respond appropriately to upsetting or uplifting events
-not let one's feelings overpower one's self
Outcomes of poor emotional health include poor social health and academic performance
social health
-Interactions with Others
• The ability to:
-interact with others individually or in groups
-use and provide social support
-adapt to a variety of social situations
• Aspects of social health, including the presence of social bonds and social supports, promote physical and mental health
• A lack of social health may result in acts of prejudice and bias towards individuals or groups
spiritual health
-an inner quest for well being
• Search for meaning, connectedness, energy, and transcendance
-Source of strength and hope
-Source of a sense of purpose
• Recognition of uniqueness, strengths and weaknesses, and place in the universe
• Spiritual health is connected to other dimensions of health
• Enhancing spiritual health is time consuming and requires effort
factors influencing psychosocial health
-external influences (we don't control)
-internal influences
External Influences (we do not control)
• Influences of the Family
-healthy versus dysfunctional
• Influences of the Wider Environment
-childhood environments
-access to services and programs
internal influences
e.g., personality traits, hormonal functioning, physical health • Self-Efficacy and Self-Esteem
self-efficacy: belief in ability to perform task successfully
self-esteem: sense of self-respect or self- worth
• Learned Helplessness vs. Learned Optimism
health indicator
An indicator is a single measure (usually expressed in quantitative terms) that captures a key dimension of health, such as how many people suffer from chronic disease or have had a heart attack. Indicators also capture various determinants of health, such as income, or key dimensions of the health care system, such as how often patients return to hospital for more care after they are treated.

"...a measure that helps quantify the achievement of a goal."
health indicators
Indicators allow us to make comparisons:
-over time (trends)
-geographic areas
-groups of people
>and focus on the most essential domains of health.
what makes a good indicator?
Data Power - high quality, available data
Proxy Power - central importance to health
Communication Power - that the meaning is transparent.
what are the bases for health indicators?
Health indicators are based upon conceptual models for what influences health status, based upon scientific research.

Models have evolved over time, as have definitions of health, but trace historical improvements in health, e.g., increases in life expectancy, declines in mortality due to infectious diseases.

Context is important: For example, in 1900 the leading causes of death were Pneumonia, Tuberculosis, and Diarrhea and Enteritis as compared to Heart Disease, Cancer, and Stroke in 2006.
current conceptual frameworks
Today's context:
Rate of healthcare spending is unsustainable, and, levels of spending not consistent with level of health. Ripe opportunities for increasing the return on investments in health through prevention.

Burden of chronic diseases (e.g., premature mortality, costs) and
Complex public health problems (e.g., violence, obesity, HIV), and health-related behaviors (e.g., smoking, diet, substance use)
The influence of social and environmental conditions on determining health outcomes, either directly or indirectly
Deep, persistent disparities in health
common frameworks for health indicators
1. Broad "Determinants of Health" - emphasizes the physical environment, social environment, health behaviors, medical care.

2. "Life Course" - emphasizes conditions/experiences early in life (e.g., 0-5) and interactions at developmental stages throughout life in optimizing our health "trajectory".

3. "Social Determinants" emphasizes educational, economic, and social conditions and interactions in shaping health.
how are health indicators used?
Indicators are powerful tools for monitoring and communicating critical information about population health.

Indicators are used to support planning (identify priorities, develop and target resources, identify benchmarks) and track progress toward broad community objectives.

Engagement of partners into civic and collaborative action (build awareness of problems and trends, generate interventions).

Inform policy and policy makers, and can be used to promote accountability among governmental and non-governmental agencies
who compiles health indicators?
-Reports are compiled at every jurisdictional level
-Provincial and local level - Health departments, foundations and philanthropic organizations, businesses, educational, law enforcement, human services providers, and other civic leaders, faith organizations, universities, media.
-National - Federal government/private partnerships.
-International - OECD, WHO
common health indicators
The most common health indicators are those related to birth and death:
-Life expectancy,
-Premature mortality (e.g., Years of Potential Life Lost or -YPLLs)
-Age-specific death rates (e.g., infants, teens)
-Cause specific deaths (e.g., lung, cervical cancer)
-Births to teens
-Very/Low birth weight
-Adequacy of prenatal care
-Social characteristics of parents (e.g, maternal educational attainment).

These are robust—high completeness of reporting, widely available through the Canadian Institute of Health Information (CIHI), and standardized so as to be are comparable across provinces and regions.
But, also limited.

-Morbidity/Health Status
-Health-related Quality of Life:
-Poor health days
-Self-rated health status

Obesity
- Body Mass Index based on self-reported height and weight

-Diabetes, asthma, and other chronic diseases.
Canadian Hospital Reporting Project (CHRP)
This online resource provides a series of 21 clinical indicators (with risk-adjusted rates) and 9 financial indicators that allows hospitals to compare their performance against those of their peers and to learn from leading practices.
CHRP
The Canadian Hospital Reporting Project (CHRP) is a national quality improvement initiative from the Canadian Institute for Health Information (CIHI). CHRP's interactive web-based tool gives hospital decision-makers, policy-makers and Canadians access to indicator results for more than 600 facilities from every province and territory in Canada.
where does CHRP data come from?
-Several CIHI data sources have been used to produce clinical and financial indicators. Clinical data is drawn from administrative health care databases, such as the Discharge Abstract Database (DAD), the National Ambulatory Care Reporting System (NACRS), the Alberta Ambulatory Care Reporting System (AACRS) and the Hospital Morbidity Database (HMDB), as well as case mix grouping data. Financial data is drawn from the Canadian MIS Database (CMDB) and the DAD.
-Hospital profile data is sourced from the CMDB, the DAD and case mix tools.
-Community profile information comes from Statistics Canada.
how does CHRP measure hospital performance?
-An indicator is a single measure that represents a key dimension of health status, the health care system or related factors.
-Indicators can be used to identify potential opportunities for quality improvement and provide a basis for comparison between hospitals or between provincial, regional and national averages.
-CHRP indicators can represent either clinical aspects of the health care system (such as patient safety) or financial aspects of the health care system (such as administrative expenses).
-These results do not provide a final conclusion about hospital performance but can be used as the first step in an improvement process to identify areas for follow-up and potential improvements.
-NO single indicator should be used to judge a hospital; it is important to consider all aspects of performance.
CHRP indicators can be used to
-Identify opportunities to improve care;
-Compare hospital performance, as well provincial, regional and national averages; and
-Evaluate practices, policies and procedures.
CHRP indicators cannot
-Provide answers—they only raise questions;
-Explain disparities, variations or change; and
-Be interpreted in the absence of context and without further analysis.
Why is CHRP publicly releasing information?
-CHRP indicators provide comparative information about hospital performance across Canada.
-This information can help acute care facilities identify areas for quality improvement.
-It enables them to foster learning and sharing of best practices, which can inspire conversations among hospital decision-makers, policy-makers and the public that can increase health system accountability and lead to better care for patients.
-Canadians can use information like this to learn more about their local hospital and about the broader health care system.
-supports transparency and accountability in the health care system.
social indicators
Physical environment:
Area-based measures, e.g., income/poverty, population density
Access to public transportation, housing
Environmental pollution, e.g., air and water quality.

Social environment:
Income (individual/family)
Education (e.g., high-school graduation rates, students reading/doing math at grade level)
Social support and connectedness.

Child and family focused:
Parental educational attainment
Parent practices (e.g., breastfeeding, reading to child, regular meal/bedtimes)
Access to services such as early developmental screening
Family social environment (e.g. parent stress, depression
Gaps in Data Sources or Measures
Examples of indicators that lack of systematically collected and standardized data:

Early life - developmental outcomes at the time of kindergarten entry and conditions throughout childhood and youth, e.g., obesity.

Later life - community care and support, long term care, quality and availability of services.

Social environments, e.g., neighborhood characteristics, quality of social interactions.
Health System Performance Indicators
Access
-All Canadians have access to health care services...BUT..
May have to travel
-Rural health provider supply, linguistic or cultural barriers to getting care

Cost
-Total health expenditures
-Health as share of Gross Domestic Product (GDP)
-Prescription drug costs
-Payments to hospitals, facilities
-Comparisons of resources used per patient between hospitals/areas

Quality of care
-Effective care - receipt of recommended screenings, -treatment, readmission rates.
-Patient Safety - medical error
measuring what matters
-Indicators are powerful
-What we count and measure, influences how we make policy decisions
If we don't measure wellbeing, in all of its dimensions, it doesn't count...leaving Canadians to:
-Gauge wellbeing using a narrow set of economic indicators
-Misinterpret wellbeing or use surrogate measures
-Ignore policy options that will fundamentally improve wellbeing
why a new measure of well being?
-Promote a shared vision of what really constitutes sustainable wellbeing and the elements that contribute to or detract from it;
-Measure national progress toward, or away from, achieving that vision;
-Understand and promote awareness of why society is moving in the direction it is moving;
-Stimulate discussion about the types of policies, programs, and activities that would move us closer and faster toward achieving wellbeing;
-Give Canadians tools to promote wellbeing with policy shapers and decision makers so as to account for why things are getting better or worse; and
-Add momentum to the global movement for a more holistic way of measuring societal progress.
vision of canadian wellbeing
To enable all Canadians to share in the highest wellbeing status by identifying, developing and publicizing statistical measures that offer clear, valid and regular reporting on progress toward wellbeing outcomes Canadians seek as a nation.
living standards
measures the quality and quantity of goods and services, both public and private, available to the population, and the distribution of these goods and services within the population.
healthy populations
measures the physical and mental health of the population - experiencing disease, disability and delaying death, people's life circumstances, and care people receive.
community vitality
measures the strength, activity and inclusiveness of relationships among residents, private sector, public sector and civil society organizations that work to foster individual and collective wellbeing.
democratic engagement
measures the participation of citizens in public life and in governance; the functioning of Canadian governments with respect to openness, transparency, effectiveness, fairness, equity and accessibility; and the role Canadians and their institutions play as global citizens.
report highlights: living standards
Canadians experienced a widening of income and wealth inequalities
The fight against poverty has stalled since 1981; some poverty reductions were not nearly as large as the increase in wealth inequality
Between 1981-2008, the incidence of long-term unemployment is higher now than in 1981
Since 1981, many dimensions of living standards in Canada have not improved, despite a 53.0% surge in GDP per capita
Frayed social safety net provides less support for the disadvantaged (e.g. welfare benefits, employment insurance less generous re: qualifications period, coverage, duration of benefits)
report highlights: healthy populations
Life expectancy rates are among the best in the world; a closer look at health indicators reveals a more mixed picture
-Canadians are living longer but not better
-Canadians are increasingly likely to develop a chronic disease or mental illness during their lifetime

For more than a decade, merely 65% of Canadians have declared their overall health very good or excellent. Self-rated health is considerably lower than it was 10 years previously
-This decline is most marked among Canadian teenagers - a drop of 11.9%

Health disparities between Aboriginal and non-Aboriginal Canadians have narrowed somewhat but still remain unacceptably large

Higher incomes and higher levels of education are associated with longer life expectancy and better self-reported health.
-The positive impact of income and education is most marked among women.
report highlights: community vitality
-Canadians have strong social relationships with their families and communities
>Positive trend of most of the indicators suggests that the wellbeing of Canadians, as measured by the quality of their relationships, is improving over time.
-We are well-equipped to deal with current and future challenges
-The size of Canadian's social networks has declined since the mid 1990s; Canadians are reporting smaller numbers of close relatives and close friends
-A growing number of Canadians report that they provide help to others (83% of Canadians in 2004)
-Over half of Canadians believe that people can generally be trusted
-In 2004, 4.1% of Canadians reported experiencing discrimination because of their ethnicity, race, culture, skin colour, religion or language, a decline from 7.1% in 2002; significantly higher for visible minorities
report highlights: democratic engagement
-Fewer Canadians are voting. Turnout in the most recent federal election, in 2008, was the lowest in Canadian history at 59.1%, down more than 10 percentage points from 1993.
-Participation rates in formal political activities are extremely low. The number of people volunteering for law, advocacy and political groups has hovered at about 2% or less throughout the past decade, and hours volunteered dropped by 15% from 2004 to 2007.
-Canadians aren't satisfied with their democracy. Between 40-45% said they were not satisfied with how democracy works in Canada. (2004 and 2006 surveys)
-An overwhelming majority of people say that federal government policies have not made their lives better. Only 12% said their lives had been improved by federal policies when last surveyed in 2006.
-Women and minorities are underrepresented in the political process. Since 1997, the percentage of women in Parliament has remained relatively steady - and low - at about 20%.

Rowe and Kahn (1987)
Successful aging implies a balance between:
-Low probability of disease and disease related disability,
-High cognitive and physical functioning, and;
-Active engagement with life.
3 theoretical perspectives
Biological age-functional capacities
Sociological age-roles and behaviours
Psychological age-behavioural capacities and ability to adapt
life expectancy and life span
-Life expectancy - the number of yrs that will probably be lived by the average individual born in a particular year.
-The life expectancy of individuals born today in the Canada is 79.9 yrs.
-Life span - the upper boundary of life; the maximum number of yrs an individual can live.
-120 years is maximum
theories
-Genetics
-Environment
-Socio-economic status
-Lifestyle
nursing goal
To develop a combination of preventative and therapeutic approaches that will allow people to age in good health
centenarians
-There are 4,320 centenarians living in Canada.
-The number is projected to increase to 45,000 by 2046.
-Many centenarians are quite healthy in their old age.
-Rapid growth in the older population will likely lead to a variety of societal changes.
Gender Differences in Longevity
-Life expectancy for females is 81.4, males 75.7.
-By age 45, females begin to out number males.
-By the time adults are 70-74 yrs of age, more than 53.4% of the population is female.
-Life expectancy differences are likely due to health attitudes, habits, lifestyles, & occupation.
-Biological factors may play a role, as females outlive males in virtually all species.

-Wait times are a major issue
-Political debates over private sector role in healthcare delivery
trends in health care
-The number of acute-care hospitals and acute-care hospital beds decreased from 1995 to 2013.
-Medical advances have led to more procedures being done on an out-patient basis, and to a rise in the number of day surgeries.
-The length of time a person could be expected to live (life expectancy) is widely used to show health status. As of 2002, the average life expectancy at birth for Canadians was 82.1 years for women and 77.2 years for men, which is among the highest in the industrialized countries.
-Services such as home care and long term care facilities are not able to meet the demand
