🙌 Congratulations to DSPI’s Dr Ismael Guillermo Muñoz on receiving a 2025 IPUMS Research Award for outstanding published research using IPUMS Global Health data.
The award recognises the paper, ‘Grandparental Co-residence, Grandchildren Nutrition, and the Role of Demographic and Health Regimes’, which explores how grandparents influence child nutrition across Africa.
Drawing on IPUMS DHS data from 29 African countries and applying multilevel regression analysis, the study reveals how the benefits of grandparental co-residence vary across different demographic and health contexts.
Key findings
▶️ Living with a grandmother is, on average, associated with lower stunting rates among grandchildren
▶️In countries with high fertility and mortality rates, living with grandparents – especially grandmothers – is linked to substantial nutritional benefits for children.
▶️ These advantages tend to diminish in countries further along the demographic and health transition, where grandparents are typically older and chronic illness and disability become more common.
The research highlights the value of combining individual-level survey data with broader population-level indicators to better understand child wellbeing across countries.
Commenting on the award, Dr Muñoz said:
“We are grateful to IPUMS for this recognition. At a time when the future of key global data infrastructures such as The Demographic and Health Surveys (DHS) is being actively challenged and redefined, their continued availability (together with IPUMS’ harmonization efforts) remains crucial for advancing research on health and inequality across different contexts.”
