Physiotherapists in primary care in the Republic of Ireland were surveyed about their assessment and management of lifestyle risk factors. The survey found that physiotherapists most commonly assessed physical activity levels, followed by dietary status. Few assessed smoking status or alcohol consumption. The main barriers to assessing these factors were lack of time, limited knowledge and expertise, and a perception that it was not part of their role. The study highlights opportunities for physiotherapists to play a greater role in addressing lifestyle risk factors through more systematic assessment and management. Training is needed to help overcome barriers identified in the survey.
