The use of house value (as defined by rateable value) as an indicator of cumulative wealth in older people: a study using the Northern Ireland Mortality study.

The use of house value (as defined by rateable value) as an indicator of cumulative wealth in older people: a study using the Northern Ireland Mortality study.

There has been relatively little research into health inequalities in older populations. This may be partly explained by the difficulty in identifying appropriate indicators of socio-economic status for older people. Ideally, indicators of socio-economic status to be used in studies of health inequalities in older populations should incorporate some measure of life-time socio-economic standing, and house value may fill this role. This study uses recently available data on the rateable value of properties in Northern Ireland which can been linked to the NILS mortality study and examines whether an indicator of accumulated wealth based on a combination of housing tenure and house value is a strong predictor of ill-health in older populations.

An exploratory analysis of adolescent dental health and use of dental care services in Northern Ireland.

An exploratory analysis of adolescent dental health and use of dental care services in Northern Ireland.

Those aged 18 and under are in Northern Ireland entitled to have their oral care funded by the health service. This care is typically provided by general dental practitioners – independent contractors – who operate on a for-profit basis. While equal access to funding exists, because care is delivered by independent contractors there is no guarantee of equal access to care in the presence of equal need. Indeed, as evidenced by wide variations in registration rates across Northern Ireland, and wide variations in registration rates both linked to deprivation, there is clear evidence of unequal access relative to need. An examination of registration alone however, provides a very incomplete picture of access to services or differences in the intensity or type of services provided. The primary objective of the proposed project is to analyse a dataset formed by linkage of the Northern Ireland Longitudinal Study (NILS) and the reimbursement of general dentist practitioner data collected by the Central Services Agency (CSA).

The Retirement Transition and the Celtic Fringe: Mobility Trends and Migrant and Rural Community Well-being?

The Retirement Transition and the Celtic Fringe: Mobility Trends and Migrant and Rural Community Well-being?

The current project seeks evidence of a ‘retirement transition’ affecting the mobility patterns of the 50 to 64-year-old age group within the UK’s Celtic fringe. The retirement transition concept refers to the behavioural changes affecting pre-retirement age groups and assumes that the expectation of retirement acts as a catalyst for change, including a change of residence. Such migration in the UK is commonly associated with peripheral and scenically attractive areas. Accordingly, the project focuses on rural areas of Scotland, Wales and Northern Ireland.

From Black to the Twenty-first century – has it changed and how would we know? - A Study of Mortality differentials by social class over time in Northern Ireland and the impact of differing approaches to measuring and comparing these.

From Black to the Twenty-first century – has it changed and how would we know? – A Study of Mortality differentials by social class over time in Northern Ireland and the impact of differing approaches to measuring and comparing these.

This is a study to be submitted in partial fulfilment of the requirements for an MSc in Health Informatics. The study looks at the various ways of measuring comparative mortality across social class and deprivation over time using Northern Ireland data. Using vital registration data for NI as a primary source it compares age std mortality rates for a range of diseases, life expectancy and potential years of life lost over time in Northern Ireland. From the NILS mortality dataset, it is intended to directly compare the 2001 census assignment of social class with that on death registration for deaths post 2001 by age group and to compare the mortality rates using the census social class with GRO’s version for the NILS population who have died in the period 2002-2006.

Utilising and combining the Longitudinal Studies of England and Wales, Scotland and Northern Ireland: developing a unified approach to investigating UK-wide regional differences in health, coupled with an exemplar analysis of the relationship between self-reported morbidity and mortality.

Utilising and combining the Longitudinal Studies of England and Wales, Scotland and Northern Ireland: developing a unified approach to investigating UK-wide regional differences in health, coupled with an exemplar analysis of the relationship between self-reported morbidity and mortality.

There are now three Census-based record linkage studies covering the constituent parts of the UK: The Office for National Statistics Longitudinal Study (ONS LS) of England and Wales (established in the mid-1970s); the Scottish Longitudinal Study (SLS); and the Northern Ireland Longitudinal Study (NILS) – the latter two launched in 2007. Their existence means that there is now potential to undertaking parallel and combined analyses using all three sources to examine health differentials over the whole of the United Kingdom (UK).

Social Harm and the Elderly in Northern Ireland.

Social Harm and the Elderly in Northern Ireland.

The research outlined below is part of a larger project examining significant forms of harm that can affect the elderly in Northern Ireland. These can be physical (falls, accidents, injuries), financial (income poverty, fuel poverty) or psychological (fear of crime). Figures show that these types of harm occur at a higher rate than crime, and are often much more detrimental. Also, it is argued that, by maintaining focus on crime, emphasis will remain on crime reduction strategies, increased spending in the police service, and policies of social control, resources which could be relocated to fulfilling the government’s responsibility towards older people through improved public polices and health care. The proposed NILS study examines the physical harms suffered by the elderly – specifically mortality due to falls, accidents, poisoning etc. The NILS allows analysis of the socio-demographic circumstances (such as age, gender, marital status etc) and socio-economic circumstances (e.g. education, social class, deprivation etc) associated with mortality in the elderly.

Applying modelled income indicator to the Northern Ireland Longitudinal Study.

Applying modelled income indicator to the Northern Ireland Longitudinal Study.

Small area-based measures of income are being developed through an ESNSG project with the University of Essex. These statistics will give data on the probability of households in each small area falling below a given low-income threshold. This methodology is to be extended further in a separate NISRA project which is to be applicable at a household level. The current project will apply this model to each NILS member giving the probability that their household falls below an income threshold. This modelled income probability will then be used as a proxy for income in future NILS projects such as production of mortality and fertility rates by income probability and investigation of migration patterns. However, this project will focus on providing background information and evaluating the usefulness and accuracy of results produced using the income model.

Preliminary investigation into mortality rates and expectation of life for section 75 groups and social class.

Preliminary investigation into mortality rates and expectation of life for section 75 groups and social class.

The aim of the current study is to produce a set of mortality rates and life tables relating to each of the section 75 groups present in the 2001 census along with key socio-economic measures. This will be accomplished by aggregating several years’ worth of mortality data (2001-2006) with age-standardised mortality rates and standardised rate ratios produced along with confidence intervals to allow identification of significant differences between various population groups and the general population.

Predicting Short Run Changes in Fertility in Northern Ireland.

Predicting Short Run Changes in Fertility in Northern Ireland.

Northern Ireland has in recent years shared the slight upturn in fertility evident in some European countries. This contrasts with the steady fall in fertility from the peak of the ‘baby boom’ in the 1960s that is associated with increased female participation in the labour market and delay in the age of child bearing. Any change in the pattern of fertility has profound consequences for the provision of public services, particularly in education and health care.
