Maori are being told they can do more to prevent strokes.
Waatea News reports an international research programme has found stroke rates among Maori increased by 20% over the past three decades, when the incidence among Pakeha dropped 18%.
The study was conducted in 28 countries.
Researcher Valery Feigin of AUT University says the rate of Maori increase is similar to that in developing countries, but Maori have more severe strokes than Pakeha and poorer rehabilitation outcomes.
He says many strokes are caused by the likes of smoking, poor diet and lack of exercise and are therefore highly preventable.
