| Zusammenfassung: | The National Health and Nutrition Examination Survey II: Mortality Study, 1992 (NH2MS) followed a subset of the participants in the second National Health and Nutrition Examination Survey (NHANES II). The NH2MS cohort is comprised of adult respondents to the NHANES II who were 30-75 years of age at the time of the NHANES II, and who were interviewed and examined for NHANES II. Some participants who were 74 years of age during their interview turned 75 years old between their interview and the examination. The NHANES series of data collections included standardized physical examinations, laboratory tests, and interviews that covered various health-related topics. The NH2MS was designed to investigate the association between factors measured at baseline and overall mortality or death from specific causes. The NH2MS involved searching national databases containing information about mortality and causes of death. The study was entirely passive: participants were not recontacted, nor were all death certificates obtained. Instead, mortality status was ascertained solely by computerized matching to national databases and evaluation of the resulting matches. Furthermore, no recontact is planned in the future. Rather, matching to the National Death Index (NDI) and to other national databases will continue on a periodic basis. The Mortality Status file (Part 1) contains mortality status and demographic data for all NH2MS participants who were 30-75 years of age at their NHANES II examination. The Cause of Death file (Part 2) contains one record for each known decedent for whom multiple causes of death were obtained (2,103 out of the 2,145 participants identified as deceased). Cause of death is missing for some decedents either because there was no matching record on the NCHS Multiple Cause of Death files or the death certificate was not found through the state vital statistics office.
