An Irish scientist is to lead a major research project which explores how people can be encouraged to change risky or unhealthy personal behaviours.

The impact of such interventions could be widespread and life-saving, according to researchers.

The group, led by Dr Molly Byrne, a health psychologist and lecturer at NUI Galway, will first focus on designing ways to encourage change in lifestyle which are related to diabetes and heart disease.

Speaking today, Dr Byrne said that it is clear that an increasing number of health problems in Ireland and internationally are linked to unhealthy behaviours.
