Longitudinal Research

12.8K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Area of Science:

  • Public Health
  • Epidemiology
  • Data Science

Background:

  • Excessive alcohol consumption poses significant health risks.
  • Longitudinal analysis of population data is crucial for understanding alcohol use patterns and harms.
  • The UK possesses valuable linkable, longitudinal datasets for such research.

Purpose of the Study:

  • To develop an alcohol-specific analytical platform in the UK using linked datasets from Wales.
  • To integrate existing cohorts, e-cohorts, surveys, and electronic health records (EHRs).
  • To enable population-based research on alcohol-related harm in Wales through a secure platform with derived variables.

Main Methods:

  • Cross-linking of routine and observational datasets, including hospital admissions, general practice records, and child-specific cohorts.
  • Integration of routine socioeconomic descriptors and mortality data.
  • Development of an alcohol-specific analytical platform on a secure data environment.

Main Results:

  • A record-linked, population-based research protocol for alcohol-related harm has been established on a secure platform.
  • The developed platform, ELAStiC, provides a template for similar initiatives in other countries.
  • Alcohol-specific variables derived from routinely collected data are defined for epidemiological studies.

Conclusions:

  • The established platform facilitates longitudinal research into alcohol-related disease and health trajectories.
  • The ELAStiC protocol and derived variables can be utilized in other countries for alcohol harm research.
  • Over 10 years of longitudinal data will enhance understanding of health outcomes across the lifespan.
