  1. Does where you live influence your health or the reporting of ill-health? Michael Rosato, Gemma Catney, Sheelah Connolly, Seeromanie Harding, Dermot O’Reilly

  2. Std Mortality Rates

  3. Self-reported Health Std Mortality Rates

  4. Project 019: Variations in alcohol related deaths in Northern Ireland Background: • Globally 4% of all deaths • Impact on crime, productivity and families • Costs ~£20billion/year in England • Epidemiology not entirely clear • Ecological studies show strong association to area deprivation and urban living

  5. Source: Registrar Generals Office

  6. Aims • To examine differences in alcohol-related mortality between areas • Urban/rural • Affluent/deprived • To determine if these differences were due to characteristics of the individuals living in these areas or to specific area effects.

  7. Data (i) • Northern Ireland Mortality Study (NIMS) • 720,627 people aged 25-74 • Non-institutionalised • Age, sex, marital status, • LLTI & GH • SES, NS-SEC, Educ attainment, • Housing tenure & cars (for area deprivation only) • Area: • Income domain of NIIMD • Settlement band (Urban, intermediate, Rural)

  8. Data (ii) ICD-10 codes for alcohol-related deaths: F10—mental and behavioural disorders due to use of alcohol; G31.2 - degeneration of nervous system due to alcohol; G62.1- alcoholic polyneuropathy; I42.6- alcoholic cardiomyopathy; K29.2- alcoholic gastritis; K70- alcoholic liver disease; K73- chronic hepatitis, not elsewhere classified; K74- fibrosis and cirrhosis of liver (excluding K74.3-K74.5—biliary cirrhosis); K86.0- alcohol-induced chronic pancreatitis; X45- accidental poisoning by and exposure to alcohol; X65- intentional self-poisoning by and exposure to alcohol; and Y15- poisoning by and exposure to alcohol, undetermined intent. Deaths: 5-years follow-up 578 alcohol related deaths

  9. Results:

  10. Association with area deprivation

  11. Association with urban/rural

  12. Conclusions: • Higher mortality risk for disadvantaged individuals. • No independent effect of area deprivation. • Mortality lower in rural areas. Explanations for these findings?? Area of residence and alcohol-related mortality risk: A five–year follow-up study. Connolly S, O’ Reilly D, Rosato M, Cardwell C. (Addiction DOI: 10.1111/j.1360-0443.2010.03103.x)

  13. Project 011: Area influences on health: does community or religious segregation matter?

  14. Background/theory • Good • Bad Aims: • Variations in mortality risk across different levels of denominational concentration • Variations in cause-specific mortality

  15. Distribution of population

  16. Mortality risk according to level of dissonance

  17. Mortality risk by level of concordance Model 1 is adjusted for age(in 5-year bands), sex and marital status; Model 2 is Model 1 further adjusted for educational activity, NS-SEC, housing tenure, car availability, economic activity, house value and settlement band

  18. Variations in cause-specific mortality

  19. Conclusions • The more polarized areas are the most deprived • Mortality is higher in the more polarized areas • The higher mortality in concordant areas is due to SES. • The higher mortality of Catholics in Protestant areas (and to a lesser extent, of Protestants in the most Catholic areas) is unexplained. • Clues in cause-specific mortality? • Overall living in discordant areas may be bad for health??? • Other explanations are possible

  20. Project 015: The socio-economic (& cultural influences) on the perception & reporting of self-reported health in NI Does a weak labour market make people feel sick? Dissonances in self-reported health and mortality across denominational groups in Northern Ireland O’ Reilly D, Rosato M. Soc Sci Med 2010; 71: 1011-1017

  21. Self-reported Health Std Mortality Rates

  22. What happens when people become unemployed? U/E benefits Work No work Health-related benefits

  23. Hypotheses • Where labour market is poor people are more likely to report ill-health • The relationship between SRH and mortality should vary according to strength of labour market Aims: • Logistic regression to explore relationship between labour market and levels of ill-health • Cox proportional hazards to investigate effect modification by areas on SRH-mortality relationship

  24. Data & methods • NIMS with ‘usual suspects’ • Labour market • %working age who are U/E or permanently sick • <10%; 10%-14.9%; 15%-19.9%; 20%-24.9%; 25% and over • Good correlation with %employment; and employment domain of NIIMD • Mortality: 6.7 years of follow-up

  25. Likelihood of reporting a limiting long term illness. Data represent odds ratios (95% confidence intervals) from logistic regression models. ** Adjusted for age, sex, marital status, educational attainment, housing tenure and car availability

  26. Additional mortality risk associated with LLTI

  27. Conclusions • Some indication that weak labour market shifts perception of health • Likelihood of reporting poor health is higher where labour market is weakest • Relationship of LLTI to mortality is modified by labour market • Does this have repercussions for the health services?
