Biological variation of laboratory analytes based on the 1999-2002 National Health and Nutrition Examination Survey.
OBJECTIVE Biological variation consists of within-person (WP) and between-person (BP) variation. These components of biological variation are used to set analytical goals for imprecision and bias, evaluate serial changes for individual analytes, and assess the clinical utility of population-based reference intervals. Estimates of WP coefficients of variation (CVw) and BP coefficients of variati...
متن کاملBiological variation of hematology tests based on the 1999-2002 National Health and Nutrition Examination Survey.
OBJECTIVE Biological variation consists of between-person (BP) and within-person (WP) variation. Estimates of WP coefficients of variation (CVw) and BP coefficients of variation (CVg) for hematology laboratory tests were estimated from the 1999-2002 National Health and Nutrition Examination Survey (NHANES). METHODS NHANES is a survey of the civilian noninstitutionalized U.S. population that u...
متن کاملUrinary Concentrations of Metabolites of Pyrethroid Insecticides in the General U.S. Population: National Health and Nutrition Examination Survey 1999–2002
BACKGROUND Pyrethroid insecticides are the most commonly used residential insecticides in the United States. OBJECTIVES Our objective was to assess human exposure via biomonitoring to pyrethroid insecticides in a representative sample of the general U.S. population >or= 6 years of age.

متن کاملAssociation between Blood Lead and Walking Speed in the National Health and Nutrition Examination Survey (NHANES 1999–2002)
BACKGROUND Walking speed is a simple and reliable measure of motor function that is negatively associated with adverse health events in older people, including falls, disability, hospital admissions, and mortality. Lead has adverse affects on human health, particularly on the vascular and neurological systems. OBJECTIVE We explored the hypothesis that lead is associated with slower walking sp...
متن کاملCognitive function, habitual gait speed, and late-life disability in the National Health and Nutrition Examination Survey (NHANES) 1999-2002.
BACKGROUND Both cognitive function and gait speed are important correlates of disability. However, little is known about the combined effect of cognitive function and gait speed on multiple domains of disability as well as about the role of gait speed in the association between cognitive function and late-life disability. OBJECTIVE To investigate (1) how cognition and habitual gait speed are ...
