Finding a way to narrow a life expectancy swing of six years in different parts of the Royal Borough is one of the first challenges for a new health body.
The figures, based on death rates between 2006 and 2010, highlight a life expectancy gap of 6.1 years for men and 2.1 for women in unnamed borough wards.
The council’s strategic director of adult and community services Christabel Shawcross has said the board will be looking at ways to close the gap.
The newly-implemented group will meet four times a year and is formed of 10 members including councillors and council officers.
They will influence the Royal Borough health services with a key focus on reducing inequalities in health.
Chairman of the board Cllr David Coppinger (Con, Bray) said: "Reducing the six year gap could take up to 20 years to achieve, but we will be happy to see even the slightest of change within the next six months.
"What is most significant about the new board is how for the first time we can really tackle problems at ward level."
Cllr Coppinger added the board will be focusing heavily on offering support to dementia patients and strategies to prevent the high number of falls experienced by the elderly.
Decisions over how the board will begin implementing these changes is due to be confirmed in July.
