Background-Analytic guide lines were first created in 1996 to assist data users in analyzing data from the Third National Health and Nutrition Examination Survey (NHANES III),conducted from 1988 to 1994 by the Centers for Disease Control and Prevention's National Center for Health Statistics. NHANES became a continuous annual survey in 1999, with d...

In 1999, dual-energy x-ray absorptiometry (DXA) scans were added to the National Health and Nutrition Examination Survey (NHANES) to provide information on soft tissue composition and bone mineral content. However, in 1999-2004, DXA data were missing in whole or in part for about 21 per cent of the NHANES participants eligible for the DXA examinati...

It is possible to use different methods to weight National Health and Nutrition Examination Survey (NHANES) data. Typically when weighting NHANES data we use a weighting class approach of predefined cells based on a limited number of variables. However, there are model based alternatives that allow for more flexibility in calculating the statistica...

The National Children's Study is a national household probability sample designed to identify 100,000 children at birth and follow the sampled children for 21 years. Data from the study will support examining numerous hypotheses concerning genetic and environmental effects on the health and development of children. The goals of the study present su...

This paper explores three issues related to the 2000 Centers for Disease Control and Prevention growth charts. First, it clarifies the methods that were used to create the charts as it has become apparent that the smoothing techniques have been somewhat misunderstood. The techniques included smoothing-selected percentiles between and including the...

... Obesity has been reported as leading cause of gallbladder disease in children [9]. The epidemic extreme childhood obesity [10,11], presumably due to shift in nutritional habit may lead to increasing children and adolescents gallbladder diseases. Although obesity is a common cause of gallstone in adult [12], children gallstone, though rare, can be attributed to chronic hemolysis among other risk factors [13,14]. ...
... This review found that four studies initiated intervention during the postpartum period [20][21][22][23] while three began during pregnancy and extended to the postpartum period [18•, 19, 24]. Postpartum weight retention is influenced by gestational weight gain [26] and pre-pregnancy body mass index (BMI), with over 60% of individuals having a pre-pregnancy BMI in the overweight or obese range [27,28]. For those individuals with pre-existing CVD, obesity increases the risk of maternal cardiovascular complications [29]. ...
... The exposure prevalence trends we observed may be partly explained by factors external to the study, such as changing demographic characteristics of the source populations, or internal factors, such as changes to the CATI. The racial/ethnic distribution of NBDPS control mothers was similar to the distribution of pregnant women who participated in the National Health and Nutrition Examination Survey (NHANES) from 2001-2006, which was comprised of 55.9% non-Hispanic white women, 16.9% non-Hispanic black, 17.0% Mexican American, and 10.2% women who reported other race/ethnicity (Mirel et al., 2009). However, comparing the racial/ethnic distribution in the NBDPS with NHANES is somewhat limited by the oversampling of pregnant women in NHANES, which resulted in a slightly higher proportion of Mexican American women and a lower proportion of non-Hispanic white women in the pregnant cohort than was observed in the non-pregnant cohort. ...
... It is conducted by the U.S. Centers for Disease Control and Prevention (CDC) and published in two-year waves. Urine 2,4-D has been measured as part of a randomly selected environmental exposure subsample, typically representing around one-third of the overall sample [12]. Spot urine samples collected during scheduled appointments at a mobile examination center were immediately aliquoted and stored at − 20 degrees Celsius prior to shipping for analysis at CDC's National Center for Environmental Health in Atlanta, Georgia [13]. ...
... Sample weights (provided with the NHANES files) were used to account for the complex, multistage, probability sampling design. The weighting of NHANES data allows for extrapolation of study findings to the U.S. national population [59] and takes into account the unequal probabilities of selection resulting from the sample design, non-response, and planned oversampling of certain population groups [60]. ...
... Conducted by the National Center for Health Statistics at the Centers for Disease Control and Prevention, NHANES is a cross-sectional, nationally representative survey of the non-institutionalized civilian population of the United States designed to examine demographic, socioeconomic, health, and nutrition information. To ensure that samples are representative, data from the NHANES are collected with a complex, multistage probability design that identifies strata based on geography and a proportion of minority populations (17). ...
... Predictions of life expectancies for the average person are usually obtained from national life tables stratified by age, sex, and race [5]. However, the survival experience of the average person does not fully account for other important prognostic factors of premature death, such as health status, comorbidity, and various behavioral and socioeconomic risk factors. ...
... Based on tuberculin skin test results, the estimated national prevalence of latent tuberculosis infection (LTBI) among adults was 11%-18% in 1971-1972 but has remained ≤6% in subsequent NHANES cycles (1)(2)(3)(4). A single 2-year NHANES cycle is designed to produce accurate and stable estimates for conditions of ≥10% prevalence in the noninstitutionalized civilian U.S. population (5)(6)(7), suggesting that NHANES might no longer be as nationally representative for LTBI as it is for more common health conditions. Approximately 30 counties were selected for each 2-year cycle (5). ...
... This was a retrospective study based on the 2005-2018 NHANES database. The NHANES is a nationally representative survey conducted by the National Center for Health Statistics of the Centers for Disease Control and Prevention to assess the health and nutritional status of noninstitutionalized, community-dwelling adults and children in the United States [18]. Written informed consent was signed by all study participants. ...
... To illustrate, if weights are a function only of strata, then records with the same weight come from the same stratum, and it might then be easy to determine which stratum is which. Other risks include using weights to link records to primary sampling units (PSUs) even when geography is reported only very coarsely, and using replicate weights provided to facilitate variance estimation to re-identify suppressed design variables (Lu and Sitter, 2008;Park et al., 2006). If stratum-defining variables have been retained but altered for purposes of SDL-for instance, by swapping-weights may be used to detect or even reverse the SDL. ...
