How a poor childhood can affect health in later life

Children who are exposed to abuse, domestic violence or other stresses are far more likely to develop long term health problems, says new research.

The Public Health Wales study looks at adverse experiences in childhood (ACEs) which include parents separating.

Children with four or more ACEs, around 14%, are three times more likely to get lung or heart disease later in life.

One senior health figure said instead of "mending broken adults" a focus was needed on "building stronger children".

Prof Mark Bellis explains to BBC Wales health correspondent Owain Clarke how bad experiences can have a real effect.
