Projekttitel / Project title

Interplay between diabetes and intergenerational transmission of health determinants over the life course

Projektbeskrivelse / Project description

The overall aim of this project is to identify the contributions of family and early life determinants on the development, management, and care of diabetes and the diseases that may arise following a diabetes diagnosis, under a life-course framework.

Diabetes is a complex, multi-factorial disease. Its development depends on the timing and accumulation of exposures throughout the life-course. In addition to genetic influences, behavioral risk factors and socioeconomic conditions cluster in families and are passed through generations. For instance, poor childhood socioeconomic status (SES) can impact final educational attainment, adult SES, and lifestyle and behavioral characteristics, which ultimately influence an individual’s metabolic capacity to regulate glucose and subsequent risk for diabetes.

This project will contribute to a broader and deeper understanding of the role that these factors play with the development and progression of diabetes. For this purpose, we will apply causal and predictive statistical methods to best use the data available from the integrated data sources with an overarching goal to model several potential public health strategies that might impact the prevention and management of diabetes and the diseases that follow its diagnosis.

Population / Population

In order to identify familial relations through individuals’ life course trajectory, the population requested covers all individuals, who were alive in Denmark from 1 January 1970 to 31 December 2020 (~8.5 million people). The family linkage and structure makes the construction of the population complicated and we will do this ourselves. For that we need the entire population because we need data on not just the individual, but also the family (parents and siblings). To characterise early life and early childhood conditions of an individual person, we need data on their parents. Likewise, to understand the role that the family network, including siblings and grandparents, has on diabetes risk, we need a large enough population to make these linkages and to adequately study this area. Key requirements are:

  • All index individuals born or who migrated into Denmark.
  • All family members of the index individuals, including parents, siblings, spouses, and children.

Variabelindhold / Variables included

All variables can be de-identified (direct identification is not needed). The list of requested variables is found in the tables at the end of the document in the Appendix. For all the variables, we need the data from the first year it is available to the most recent year it is available.

In the Appendix we listed the ATC codes from the prescription register and ICD-8 and -10 codes from the patient register that we need to classify diabetes and the diseases that may arise following a diabetes diagnosis.

Særligt vedr. lægemiddelsdata / Especially regarding drug data

The medication data we are requested are used in order to identify cases of disease (e.g. diabetes) that might not have been diagnosed and recorded in the patient register. The list of requested ATC codes is found in the Appendix section.

Offentliggørelse af resultater / Publication of results

Results will be published in open access scientific outlets and presented at scientific conferences.

Perspektivering / Perspective

Understanding how early life and familial factors can influence diabetes provides us with tools and knowledge to better target, intervene, and either prevent or manage diabetes and its complications. Considering the impact that diabetes as a disease itself and its related comorbidities has at the personal, public health, and economic level, any improvement in knowledge can have major impacts.
