  1. Sampling Frames and Study Types Studies on life events Dr Magnolia Cardona Coordinating Epidemiologist Queensland Health Department Australia

  2. Objectives • Identify study types for life events • Propose data sources for life stages • Select best approaches to investigate • State advantages of data sources/study types • Highlight limitations

  3. Life events • Pregnancy & childbirth • Infancy & childhood • Adolescence & young adulthood • Adulthood • Mature age • Death

  4. Data Sources (pregnancy/childbirth) • Births register • Perinatal data collection • Hospital inpatients collection • Census data

  8. Selection of study types • According to research question • Whether there is a sampling frame • Topic and expected response rate • Time available for study • Financial constraints

  9. Scenarios [1] • Prevalence of falls in the elderly • Injury surveillance database/A&E Depart. • Doctors sentinel surveillance • Population survey using RDD • Electoral roll • Veteran Affairs register/Pensioner’s lists CROSS-SECTIONAL SURVEY and DATA ANALYSIS FROM EXISTING COLLECTION

  16. Limitations • Not all databases cover all aspects to be investigated • Not all populations are identifiable or approachable • Different definitions of data items in each State/region • Budget & time constraints preclude rigorous studies

  17. Summary • Life Cycle • Data Sources available • Choice of study types • Limitations Use resources to the best of your ability
