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

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

Why should health inequalities be reduced

A

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.

All other attributes

44
Q

Population pyramids

A

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
Q

Demographic transition

A

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
Q

List the 4 Demographic transitions

A

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
Q

Causes of population ageing

A

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
Q

Numerical ageing

A

Absolute increase in number of elderly.

(not needed)Reflects improvements in life expectancies unaffected by current birthrates

49
Q

Structural

A

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
Q

Natural decline

A

when deaths overtake births

51
Q

Absolute decline

A

insufficient migration to replace lost births and more deaths

52
Q

Area level deprivation

A

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
Q

NZ DEP

A

uses census data under 9 domains for one index

54
Q

IMD

A

uses IDI data under 7 domains that can be separated. Identify concentrations of deprivations

55
Q

Social fragmentation

A

How well a society combines

56
Q

What characterises big data

A

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
Q

Where is Big Data obtained

A

it is important to consider who is missed

Electronic medicine, health record
research databases
social media

58
Q

How does big data differ from conventional epidemiological sources

A

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
Q

The 7 Vs of Bigdata

A

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
Q

Data-linkage

A

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
Q

What are 3 challenges of big data

A

Governance:storage, access and privacy
Data generation:capturing, curating consistency accuracy
Data output: analysis, generating, meaningful and reliable outputs

62
Q

5safes of Big Data

A

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
Q

Policy implications of using Big data

inadvertant discrimination of subpopulations
anonymity is not guaranteed
informed consent of data sharing
privacy policies

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
Q

Pros of IDI

A

Linkable,
accessed in safe haven
