Washington [US], April 25 : The University of the West of Scotland (UWS) researchers discovered a relationship between loud road traffic and air pollution and an increased incidence of hypertension, a major risk factor for heart attack and stroke.
The study looked at the relationship between environmental quality and direct health impacts, monitoring traffic noise at different frequencies and registered hypertension cases in a number of locations in urban Glasgow. A significant correlation between noise, air pollution and hypertension were observed within high-traffic-flow residential areas.
This research provides an important case study for an increasing international evidence base to support future environment policy and support public health measures, such as setting stricter noise guidelines and improving technology on quieter vehicles and urban design.
Professor Andrew Hursthouse, lead supervisor, UWS's School of Computing Engineering and Physical Sciences, said: "This work is the result of an interdisciplinary collaboration with Mr Jan Miller, HLS and Dr Del Boakye, formerly HLS, to support the efforts of PhD student Wisdom Adza, highlighting the potential of joining skills to address societal problems.
"The increasing evidence highlighting environmental conditions and public health impacts is a game-changer when it comes to the prevention of hypertension at individual and societal level."
The research demonstrates that multiple environmental indicators can be combined to provide information to support impact assessment for public health in urban environments. Additionally, the findings could support local authorities in planning and managing the built environment, as well as affording opportunities for tools to be developed to improve public heath decision making.
Mr Wisdom Adza, UWS PhD student, and main investigator of the study, added: "A review of this area identifies opportunities for including broader indicators in public health policy.
"Although further investigation is needed, this should not delay actions to recognise that traffic noise is a potential risk factor for hypertension, and heart diseases more generally, in the development of clinical guideline and environmental policy."
