This means that where in the past infections were considered the greatest challenge, now even in the poorest countries the biggest health burdens for older people come from conditions such as heart disease, stroke, cancer, diabetes, dementia and sight and hearing loss.
WHO says present health systems are poorly designed for the chronic care needs arising from this pattern of disease. The campaigning organisation HelpAge International welcomed the new focus on the impact of ageing but the global community was still worryingly slow to act.
HelpAge cited Ghana where it said nearly 60% of older people suffer from high blood pressure often leading to strokes and heart attacks but only 5% are able to control it through medication.
