CLESA (Cross-national, Longitudinal, European Study on Aging)

Introduction

 

The increased use of data from multidisciplinary, longitudinal studies on aging is providing fresh insights into the dynamic processes that shape later life. These include transitions in health and functional status and incidence of major chronic conditions, such as cancer, dementia, osteoporosis, cardiovascular disease, diabetes. Comparing findings from longitudinal studies across time and cross-nationally is an efficacious step to pursue for increasing our knowledge-base and devising effective policies. However, there exist major obstacles to achieving these goals. In general, there is a lack of standardization in conceptual design, measurement, data collection procedures and analytic approaches. Designing next generation of longitudinal studies requires careful review of current state in the field, from both substantive and methodological points of view. Therefore, a clear and compelling need exists to draw researchers together to address the current effectiveness of longitudinal research in a systematic manner and to plan for collaborative efforts on aging research, from basic science to clinical and epidemiology research.

Methods

  • The "Cross-national determinants of quality of life and health services for the elderly" (CLESA) is a 3 year project supported by the European Commission within the V Framework Program, Key Action 6 "The Ageing Population and Disabilities".
  • The project aims at the identification of the determinants of quality of life and health services in older people resident in Finland, Israel, Italy, The Netherlands, Spain and Sweden.

Conclusions

Significant homogeneous predictors of mortality:

  • 80-84 ys (1.57), males (1.6), smokers (1.17), alcohol drinker (0.75), heart disease (1.3), stroke (1.39), cancer (1.75), respiratory disease (1.22).
  • Not significant homogeneous predictors of mortality: manual work, hypertension.
  • Heterogeneous predictors of mortality: marital status, education, drugs use, diabetes, musculoskeletal disease.
  • Traditional country-specific predictors (age, sex, smoke and alcohol) hold significant at "CLESA" level.
  • Heart disease, stroke, cancer and respiratory disease in spite of having different distribution across countries, are homogeneous predictors of mortality.
  • Manual work and hypertension are in the path-way for the above factors and conditions leading to death, and are not directly causes of death.
  • The heterogeneity of the other predictors may be explained with the differences in the socio-cultural environment and health services organization.
