Q

How is ethnicity data usually recorded

A

responses are converted into numerical form. From level 1 to level4. Responses are first recorded at level 4 and level 4 is the most detailed.

Q

Total response output

A

Each respondent is counted in each ethnic group reported.
The sum of ethnic group population will exceed that of NZ. If 2 ethnic groups are the same (at level1?), they are counted at that level once

Q

What are the strengths and weaknesses of total response output

A

Strength: follows the concept of self-identification (non alterring responses) and has the potential to represent people who don’t identify with any given ethnic group

Weaknesses: Can create complexities in distribution of funding and in monitoring changes in ethnic composition. This creates issues in data interpretation as comparisons between group include overlapping data

Q

What is prioritised output

A

Allocates a single prioritised ethnic group to individuals, regardless of the number of ethnicities responded with. It is a reduction process and does not assume it is their strongest ethnicity.

Q

What is the strength of prioritised output

A

Ensures that ethnic groups of policy importance or small size are not swamped by the NZ European group. Data is easy to work with as each person appears only once. It is widely used for funding calculations, ethnic composition monioring

Q

Education

A

it is a pathway to income opportunities. It is vital for health literacy-a person’s ability to take on health messages, pick up on signs of illness in themselves and understand the health informational services available to them in order to make appropriate health decisions

Q

Housing

A

Many families now spend a greater proportion of household income on housing costs, which leaves less money for other items essential to good health ( nutritious food, education, health services) and also leads to the sharing of accommodation causing overcrowding, which could directly impact physical and mental health

Q

Social cohesion

A

People with strong family, cultural and community ties tend to have better health than those who are socially isolated(single parents, elderly, disabled, mentally, low access to phones, motor vehicles). Unemployment and high mobility also reduce social connectedness

25
Why should health inequalities be reduced
it is equitable: People have little control over socio-economic factors detrimental to their health. Factors will improve an individual's choices and capability to succeed in life. they are avoidable:The fact that they vary over time and region proves they are reducible. Health inequalities stem from government policy options and are therefore reducible. Since these differences in health status are not biologically determined, they are avoidable They affect everyone: Inequities have flow on effects into wider society, affecting economic productivity and escalating crime, violence, communicable diesease and drug/alcohol misuse Reducingthem has economic benefits: It enables the workforce to be healthy as well as highly skilled and reduces expenditure on treatment services. Interventions are cost effective and efficient and reallocation resources to target socioeconomic disparities results in lower costs and greater marginal benefits.
26
Agency
A person's autonomy and capacity to make free choices
27
Structure
social and physical environmental conditions that influence choices or opportunities
28
Proximal
A determinant that is readily/directly associated with the change in health status
29
Distal
A determinant that is distant in time/place from the change in health status. More stable and harder to change. Acts on the more proximal determinants
30
Pro-social behaviour
social networks that are health promoting
31
Braided approach
acknowledges the existence of different beliefs, perspectives and ideas for approaches and the necessity for us to look upstream
32
Web theory
A multifactorial model of causality-health is affected by many interlinked factors The issue is makes people feel less control over their health
33
Habitus
The lifestyle, values, dispositions and expectations of a particular social group ( can be changed but ability to change varies between groups)
34
Unconscious bias
did we do this?
35
Deprivation
A state of observable and demonstrable disadvantage relative to the local community/wider society to which an individual/group belongs
36
Poverty
A lack of income/resources to attain a normative standard of living
37
Impoverished
A person who lacks the means to participate meaningfully in society. This may be macro/micro or social exclusion.
38
Lorenz curve
Acumulative frequency graph of the proportion of wealth shared by different proportions of a population, The more concave the line is, the greater the income inequality in that population
39
Line of absolute equality (Lorenz curve
This shows what a perfectly equal income distribution would be
40
Line of absolute inequality
This shows a perfectly unequal income distribution. y=0% for all x under 100%
41
Gini coefficient
a measure of the inequality shown by a lorenz curve A gini coefficient of 0 expresses perfect equality and one expresses maximal inequality
42
Population structure
age and sex distribution
43
population composition
All other attributes
44
Population pyramids
shows age sex distribution, used to look at trends in the past to extrapolate the future. There are 3 kinds EXPANSIVE: low life expectancy young population, high potential for growth, and found in developing nations ConstrictiveL Elderly population, shrinking population. High social economic development country Stationary: little to no population growth. Uniform across age groups. Developed dnations. HIgh quality of low birth rates
45
Demographic transition
Explains a global phenomenon of change in population demographics. Shows how relative changes in birth and death rates affect population structure in stages. A country progresses through the stages as social and economic forces act on it
46
List the 4 Demographic transitions
Stage1: prior to industrial revolution-high death rates, high birthrates, so fairly constant population size. A big foundation to support the elderly Stage2: Decline in death rate, first in infant mortality as there are advancement in health and sanitation. Same high birth rates=compounding of population growth. Population becomes younger Stage 3L Fertility rates decline due to change in women's status, access to contraception. Lower rate of population growth, structural aging 4:Low fertility and mortality converge again, stabilises again. Equal proportions of elderly and child dependancy. Developed countries today.
47
Causes of population ageing
low fertility Increased life expectancy Migration driven: gains at older ages, losses at younger ages Premature ageing: double impact as emigration of reproductive age people removes the children they have
48
Numerical ageing
Absolute increase in number of elderly. (not needed)Reflects improvements in life expectancies unaffected by current birthrates
49
Structural
Increase in the proportion of population that is elderly (driven by decreasing fertility rates that decrease proportion of young people. Slower, partially amenable to policy intervention.
50
Natural decline
when deaths overtake births
51
Absolute decline
insufficient migration to replace lost births and more deaths
52
Area level deprivation
A way of measuring people's relative position in society. We rank small populations, not indiviudals. It focuses on material deprivation and is an average composite measure so may under or overestimate the plight of individuals resulting in bias
53
NZ DEP
uses census data under 9 domains for one index
54
IMD
uses IDI data under 7 domains that can be separated. Identify concentrations of deprivations
55
Social fragmentation
How well a society combines
56
What characterises big data
large complex datasets (like 1 terabyte of storage) Has large amounts of infomation at the population, regional and local level Information spans different geographic areas It combines data from multiple sources to explore population health outcomes
57
Where is Big Data obtained
it is important to consider who is missed Electronic medicine, health record research databases social media
58
How does big data differ from conventional epidemiological sources
confidence intervals are higher (less relevant) All existing types of studies can be done Can use data to see patterns, trajectories in whole populations Can triangulate with different data sources so better coverage of population A transactional (activity-based population) dataset
59
The 7 Vs of Bigdata
Volume-requires a very large computer capacity for processing/analysing velocity:speed at which data is created and analysed Variety: the range of sources of data Veracity: the accuracy, credibility to reach objective decisions Variability-the high reproducible internal consistency Value-costs of storage, analysis, analysts, and actually creating these computers Visualisation: to show non-bland
60
Data-linkage
The process of combining data from different sources into one dataset based on key information DeterministicL exact matches of personal information Probabilistic: use statistical weights for data that may not exactly match
61
What are 3 challenges of big data
Governance:storage, access and privacy Data generation:capturing, curating consistency accuracy Data output: analysis, generating, meaningful and reliable outputs
62
5safes of Big Data
Safe people: researchers must have proven skills, betrusted, sign a declaration of secrecy Safe projects: must have statistical purpose and be for the public good. Are restricted to analysis of large groups not individuals Safe settings: securing arrangements, prevent unauthorised access to data safe data: deidentify data Safe output: random rounding and deidentification of published results
63
Policy implications of using Big data
inadvertant discrimination of subpopulations anonymity is not guaranteed informed consent of data sharing privacy policies
64
Privacy
ability of a person to control availability of info about themselves
65
Security
How the agency stores and controls access to information
66
Confidentiality
Protection of info and preventing disclosure to unauthorised entities
67
cons of the IDI
Only as good as the data in it Resident population definitions vary Can't use to deidentify data to follow people using services or tailor to people at risk or identify people abusing the system L
68
Pros of IDI
Linkable, accessed in safe haven de-identifcation allows system wide insight predictive risk model identify rip factors identify features of groups with a particular outcome
69
What do the 3 articles of the treay of waitangi
Art I: constructuion of state sector who got to vote Art ii: gave maori sovereignty over their own lands Art iii: equal citizenship/ different denied citizenship
70
Why is the Maori text increasingly recognised
because more Hapu signed the Maori text Those who signed it fully knew what they were agreeing to International legal priciple grants and preference
71
Socioeconomic position
The social and economic factors that influence wat positions individuals or groups hold within the structure of a society
72
Why measure SEP
used to quantify the level of inequality within or between societies May highlight changes to population structures over time, between census periods or between generations Are needed to help understand the relationship between health and other social variables Have been associated with health and life chances for as long as social groups have existed
73
How is SEP measured for individuals
``` Education Income Occupation Housing Assets and wealth ```
74
How is SEP measured for populations
``` Area measures -deprivation -access Population measures -income ineuality -literacy rates -GDP per capita ```
