Record linkage, connecting health records for the same person across different datasets, is crucial for epidemiological studies, especially in nutrition research. This method enhances data quality and research potential while raising ethical considerations.

Area of Science:

  • Epidemiology
  • Biostatistics
  • Public Health

Background:

  • Record linkage involves consolidating individual data from disparate sources.
  • This technique is vital for comprehensive epidemiological analysis.
  • Its application is particularly relevant for nutrition and food-related studies.

Purpose of the Study:

  • To provide an overview of record linkage in epidemiology.
  • To highlight its specific applications in nutrition and food studies.
  • To discuss the impact and ethical considerations of record linkage.

Main Methods:

  • Description of epidemiological methodology and its goals for record linkage.
  • Explanation of the mechanics of record linkage and its effect on data quality.
