of dementia.The study shows that the elderly is nine percent of the total population in lowand
middleincome countries today.However, the number is growing quickly.It is likely to reach twenty
percent of the total population by the middle of the century.

An article published in the Lancet medical journal dealt with a special issue on disability.It was a
study on disability and children in eighteen lowand middleincome countries.It indicated that in almost
half of the countries, children who were breastfed were less likely to have a disability than those who
were not.The same was true of those who had a deficiency of vitamin A and those who were
underweight.Children who did not take part in early learning activities or attend school were also more
likely to be disabled than those who did.
