Health related quality of life and satisfaction with lifein Croatia Gorka Vuletic, BPsychol, PhD Andrija Stampar School of Public HealthMedical Faculty, University of ZagrebCroatia
Republic of Croatia • One of 6 former Yugoslavian republics • Estimated Croatian population cca. 4,500,000 • Capital city Zagreb ~ 800,000
How did Croatia become involved in QoL research? Deakin Uni 2001-2002 (PhD research) = basis for further research in Croatia The 2003 Croatian NationalHealth survey Through the survey we obtained Population normative data for: • Subjective quality of life (satisfaction with life) • Health status (SF-36)
ProjectCroatian National Health Survey 2003 • Founded by World Bank • Co-operators: • Republic of Croatia Ministry of Health • Canadian Society for International Health • Project team was formed from: • Andrija Stampar School of Public Health & National Institute for Public Health
Sample • 10,766 households were selected to participate in the survey (based on Census 2001). • Out of these selected households a response was obtained from 9,070individuals (overall response rate 84.3%). • The questionnaire was administered face-to-face to respondents by trained public health nurses. • Representativefor Croatian adult population in terms of its regional, gender and age structure.
Participants were asked about illnesses, health related behaviour, health related quality of life, use of health care services and subjective quality of life. • Health related quality of life was measured by → Health status questionnaire ( SF-36) which measure self perceived health status.
SF-368 dimensions of health • Physical functioning • Role limitation due to physical problems • Pain • General health perception • Energy / vitality • Social functioning • Role limitation due to emotional problems • Mental health Scored 0-100
Measure of Subjective Quality of Life: How are you satisfied with your life as a whole? Completely Completely dissatisfied satisfied 0--------1----------2--------3--------4------5-------6-------7------8------9------10 Original scores were converted and presented in a form of percentage of scale maximum (% SM)
RESULTS Quality of life (QoL)
Croatian average satisfaction with life: Sample: N= 9,068 56.96 26.06%SM Men N= 2,888 56.22 26.04%SM Women N= 6,180 57.31 26.07%SM p = 0.064
Population mean: 60.11 25.12 %SM(based on weighted values) N= 3,479,134 According to 1991 census: population of Croatia=4 437 469
GDP per capita US $ = 7,724.2 Unemployment rate: 18% Self perceived economic status and QoL
RESULTS Health
Summaries • Older women in the worst position • Low QoL and not very good health • Difficulties in everyday functioning due to poor health

Predictors of subjective quality of life (SQOL) • Best predictors of SQOL: • Mental health (23 % variance explained) • General health (2.8 % variance explained) All together 8 dimensions explained 27% of SQOL • Subjective quality of life and health related quality of life must be measured independently/separately • Different concept & different content
Conclusion(for further health surveys in Croatia) • Importance of measuring QOL was recognised • Subjective QOL incorporated in health surveys is independent of health related QOL measures so it will be measured independently.
