Relative Health. Long-Run Inequalities in Health and Survival Between Families and Across Generations. ERC Starting Grant 2024 (2025-2029).
Worldwide life expectancy has increased strongly over the past decades, but social inequalities in health and mortality are large and increasing. In contrast to trends in socioeconomic inequality and social mobility, long-term developments in inequality in health and mortality have been poorly documented. “Relative Health” aims to quantify the level of inequality in health and mortality from a family perspective 1800-today. Characteristics that affect health and mortality accumulate in families, and thus the level of inequality in health and mortality can be quantified by addressing similarities within families in health and mortality (same-generation relatives) and intergenerational persistence of health and survival (ancestors and descendants). State-of-the-art population reconstructions cover up to 9 generations of relatives (grandparents, parents, children) in Sweden, Netherlands, and US 1800-today and contain lifespan and health information. The project lays the groundwork to generalize these estimates of family health inequality to many contexts with less abundant data sources, using survey data.
Long Live the Family: The Rise of Familial Health Advantages in Sweden (Crafoord Foundation, 2022-2024)
This project is motivated by the wide gap in the length of life by socioeconomic status: the social gradient in mortality, which emerged in Sweden in the 1950ies for women and 1970ies for men. Historically, large disparities existed in lifestyle between lower and higher classes, and higher classes in particular had increased risk of lifestyle-related disease related to smoking, drinking and a sedentary lifestyle. In turn, among lower socioeconomic status groups infectious disease mortality may have been relatively higher and persisted longer. Causes of death analyses from historical Sweden confirm this broad picture, but leave open the question when family-shared factors started to contribute to inequalities in mortality. In this project, we identify long-lived families and investigate their survival advantage over time. Even in the absence of a population-level social gradient in mortality, patterns of health and survival are and were shared in these families. The project is funded by Crafoordska Stiftelse and executed with doctoral student Isa Barraclough.
An Age-Old Advantage? Healthy aging in two centuries of Swedish and Dutch long-lived families 1813-2021 (Riksbanken Jubileumsfond, 2021-2025)
In this project, we study healthy ageing families and factors contributing to long lives and healthy ageing within them. The three-year project was funded in autumn 2021 by the National Bank of Sweden foundation (Riksbankens Jubileumsfond). Co-applicant and postdoctoral researcher on the project is Niels van den Berg, expert on healthy ageing families. Niels works at the Leiden University Medial Centre in the Netherlands. The project funds two researcher positions for three years.

Maternal and Infant Health and Their Change over Time
This digitization grant was awarded in summer 2021 by the Ebbe Kock Foundation, for the digitization of hospital birth records from Landskrona. The digitized birth records will be used for research on the relation between mother’s infectious disease exposure in early life and her reproductive career in mid-life, including her children’s weight at birth. This project was initiated and executed together with Therese Nilsson and Luciana Quaranta. Previously, we already received funding from Gyllenstiernska Krapperup Stiftelse (PI Therese Nilsson) and Ebbe Kock Stiftelse (PI, co-applicants Therese Nilsson and Luciana Quaranta) in 2020 and 2021 for two digitization projects of obstetric records, both funding research assistants entering historical records. These digitization projects are now finished and a link to our first research paper using the wonderful records can be found here.
