Título: Temperature-related mortality, longevity and ageing: novel approaches, new insights

The climate is changing, temperatures are rising, and populations are ageing: this poses a
major challenge as older people are particularly vulnerable to heat. Previous studies have
considered various aspects of heat and ageing, finding that: older people´s susceptibility to
heat is often (but not always) falling; health impacts (i.e. number of deaths) amongst older
people are rising; and, that population ageing is expected to be a major driver of future heat
deaths.
In this presentation, I´ll discuss four recent papers that attempt to provide new insights into
these issues. The analyses do so not by leveraging new data sources, but rather by rethinking
the questions of interest. For instance:
 When assessing how social predictors influence patterns of heat-related deaths, what
if we account for between-predictor interrelations? And, what if we consider how the
predictors influence absolute risk rather than just relative risk?
 When assessing the implications of ageing, what if we reconsider what we mean by
someone´s “age” and adopt a concept that better captures older people´s functioning
and capabilities?
 What if, instead of only considering the challenges of population ageing, we also ask
how has rising longevity contributed to risk reduction? And, conversely, what do we
see if we ask whether temperature-related deaths are undermining ongoing rises in
longevity?

Ponente: Simon Lloyd

He is a public health and environmental specialist with more than 15 years of
experience researching the health impacts of climate change. He spent over a decade
at the London School of Hygiene and Tropical Medicine (2007–2020) before joining the
Barcelona Institute of Global Health (ISGlobal) (2020–2024). Over this time, he has
contributed to a wide range of international, multidisciplinary research projects and has
served as a consultant for the World Bank, the World Health Organization, and the
United Nations Department of Economic and Social Affairs.

His research and publications span diverse health-related outcomes, including
undernutrition, coastal flooding, diarrhoeal disease, temperature-related mortality,
labour productivity losses, and sustainable cities. Simon’s central interest lies in
developing analyses and models that attempt to capture the complex interconnections
between the environment, society, and health.
Before moving into academia, Simon worked as a Senior Public Health Researcher for
the National Health Service (NHS) in Scotland. Earlier in his career, he practiced as a
clinical pharmacist in community and hospital settings in both Australia and England.
