Migrant workers in south Norfolk rarely use the NHS, a report has shown.
Public health project Thetford Healthy Town commissioned the report to determine the experiences of migrant workers who had used health services.
Norfolk has a high number of migrant workers and the report said "major concerns" were raised over the impact of increased migration on the NHS.
But the report found migrants made little or no use of NHS services although most registered with a GP.
The report highlighted areas for development and said migrant workers wanted longer appointments with GPs.
Chair of NHS Norfolk Sheila Childerhouse said: "NHS Norfolk is attempting to better understand the needs and issues of our many communities, including European migrants, to ensure our services continue to be relevant, responsive and of the highest quality.
"The report draws a number of valuable conclusions which we can use to develop and improve the services we provide not only to migrant communities, but also to existing communities across Norfolk."
