DR RICARDO SEGURADO
Associate Professor - UCD School of Public Health, Physiotherapy and Sports Science
Studying Statistics: Vital for Research, Vital for Health
Dr Ricardo Segurados’ work involves helping other researchers with study designs, analysing their data and interpreting their results - from a huge range of biological and medical research.
He is the deputy director of CSTAR which is the UCD Centre for Support and Training in Analysis and Research. He teaches on the CSTAR courses and is continuing to develop courses to teach people software and data analysis basics.
Through CSTAR Dr Segurado does some consulting for the National Maternity Hospital and has a current collaboration with Professor Cecily Kelleher of UCD and Professor Fionnuala McAuliffe from the National Maternity Hospital.
Their research team are examining children’s growth and development at certain time points. They are examining data such as height, weight, growth rates, body fat levels and looking for associations between these features and general health and future disease risk.
"As there is a current obesity crisis it is important to use research findings to potentially intervene in the obesity development process as early as possible in life."
Dr Segurado leads a Professional Certificate in Statistics for Human Genetics for clinicians or researchers with an interest in the chances of genetic associations having an actionable impact on a disease. Additionally, he teaches how to design studies and apply more complex statistical methods on the MSc in Public Health.
Working on clinical trial design and data analysis has impact for doctors and researchers, but ultimately might have a variety of impacts on patients and the public.
"There is a child obesity crisis as much as an adult one, so it is important to develop the methods which will let researchers know whether and when early intervention works."
This is hopefully not only to prevent later disease. Dr Segurado thinks that by preventing young children from being too overweight and obese in early life, this can help them eat healthily and exercise appropriately through the lifespan, making this a way of life they can pass on to their own children.
He also comments on potential predisposing genetic factors that may be influencing the obesity crisis.
"That is something still being researched - do maternal characteristics, such as maternal blood markers and maternal diet during pregnancy, feed into a growth trajectory which is a bit skewed in the child."
Genetic medicine is most likely to have clinical impact on rare diseases. Those are commonly caused by a once-off mutation, or one or two very rare inherited variants and usually lead to a more severe disease.
Dr Segurado says a single gene-disorder is much more amenable to developing a genetic test. Existing examples are cystic fibrosis and some of the other diseases that are currently screened for in the neonatal blood spot. Knowing when a disease with a known gene is amenable to being rolled out as a genetic test is something that both clinicians and policy makers need to have awareness of-to develop systems and services fit for purpose.
Part of what Dr Segurado does is trying to educate and set the foundations for research around genetic medicine. He thinks clinical genetics is underfunded in Ireland and thus lagging in best practice. Clinical trials must use state of the art methods or the best methods appropriate for their design and must avoid the pitfalls of conducting research using what can be quite complex measurements and systems.
Much of Dr Segurados’ work, particularly in biostatistics, has impact on other academics and their research. It enables them, teaches them and helps them get the most out of their analysis. This enhances the robustness and strength of their research.
