OBJECTIVE: The 2000 Mexican National Health Survey (NHS) was created as part of the System for National Health Surveys conducted during the last months of 1999 and the first three of 2000. The 2000 NHS is a probabilistic survey of households from which users of health services were selected according to three age groups. Information was gathered through direct interviews with appropriate informants. Biological samples were taken for clinical tests as well as for measuring biological and somatometric parameters. MATERIAL AND METHODS: The sample design of the 2000 NHS was stratified and clustered. Sample size was 1 470 households per state for a total of 47 040 households nationwide (there are 32 states in México). Sample weights were calculated and modified according to the non-response and post-stratified to calibrate for population distribution. Interviewers were trained in order to maintain a high response rate, especially for biological samples. RESULTS: A total of 83 157 blood samples were collected from the 94 000 expected (88% response rate). All samples were refrigerated immediately after collection and divided in four vials for storage at the National Institute for Public Health's laboratory. Samples were frozen at -150° Celsius until further analysis.
