Wearable cameras – the next step in heart research?
New research published today suggests that using wearable
cameras in research could help enhance our understanding of the
links between our lifestyle and health.
The research was led by Dr Aidan Doherty who
is part of the Health Promotion Research Group at
the University of Oxford. The researchers compared wearable cameras
with conventional methods for recording lifestyle behaviours such
as food diaries where people self-report their behaviours
The cameras are worn around the participant’s
neck and track every step, including what they eat
and how much they exercise. By using this technique scientists can
accurately see what effect lifestyle is having on their
risk of heart disease. The researchers found using
cameras provides a more accurate picture than if a
participant fills in a questionnaire.

“Our understanding of heart disease risk from
public health research usually relies on people self-reporting
factors like their diet and levels of exercise, which can
be unreliable. These new studies show that using cameras
to record these activities provides more accurate
information than by conventional methods.
“It’s vital that health advice is backed up by
reliable evidence. Technology like this could
revolutionise public health
research by giving us even greater insight into the
lifestyle factors that increase our risk of heart disease.”
The research was published in the American Journal of Preventive
