[The health status of the elderly population: what do we need to know?]

The objective of this research was to evaluate the data on the health of the elderly population available in the Brazilian information system and their correspondence with the North American statistics using the Internet. The North American publication "Older Americans 2000: Key Indicators of Well-Being" was used as a standard. The databases and instruments used in the North American and Brazilian surveys are presented. The North American data are based on the Supplement on Aging and Second Supplement on Aging; Health and Retirement Study; National Health Interview Survey and National Long Term Care Survey. The Brazilian data were collected from the Mortality Information System; Information System of the National Program of Immunizations; National Household Sample Survey conducted in 1998 and 2003 and from the Household Survey on Risk Behavior and Morbidity from Not Transmissible Diseases of 2002-2003. There is a great number of Brazilian information about the aged population of the Country available in the Internet and with few exceptions the information on aged Brazilians corresponds to the information available about aged North Americans.
