Plan and Operation of the Third National Health and Nutrition Examination Survey, 1988-94


Book Description

Describes the plan and operation of the third National Health and Nutrition Survey. The sample for this study of the U.S. population was selected from households in 81 counties across the United States. About 40,000 persons 2 months of age and over were selected, including large samples of both young and old persons. About 12,000 of the sample persons were black Americans, 12,000 were Mexican-Americans, and the remaining 16,000 were of all other race and ethnicity groups. All selected persons were asked to complete an extensive interview and an examination in a large mobile examination center. The survey period is 1988-94, consisting of two phases of equal length and sample size. Both Phase 1 and Phase 2 were random samples of the U.S. population living in households.

Dietary Intake and Cardiovascular Risk Factors


Book Description

Attention is directed towards possible associations between nutritional variables and coronary artery disease risk factors, based on data developed during the first US National Health and Nutrition Examination Survey (1971-75). Relative body weight (weight/height-squared) was determined to be an important predictor of serum cholesterol and urate levels and of blood pressure levels, in US adults. This predictor, together with age and sex, accounted for most of the explained variance. Dietary variables (based on results from 24-hours recall or on a food frequency questionnaire) did not influence serum cholesterol or urate levels. Alcohol intakes however, correlated directly with serum urate level. Serum Ca and Mg levels and serum glutamic oxalacetic transaminase were found to be directly and independently related to serum cholesterol and urate, which were also related to each other. Other positive and negative influences on serum cholesterol and urate levels are discussed. Summarized data concerning this study are provided.

TRANSAX, the NCHS System for Producing Multiple Cause-of-death Statistics, 1968-78


Book Description

This report describes the characteristics of the TRANSAX (for Translation of AXis) computer software developed by staff of the National Center for Health Statistics to translate multiple cause-of-death data contained on death certificates from a condition (entity) axis of classification to a person (record) axis of classification. This conversion is an essential step in the development of data for meaningful tabulation and analysis. System development, implementation, benefits, features, and applications are discussed.
