OBJECTIVES This report provides detailed information on how the 2000 Centers for Disease Control and Prevention (CDC) growth charts for the United States were developed, expanding upon the report that accompanied the initial release of the charts in 2000. METHODS The growth charts were developed with data from five national health examination surveys and(More)
OBJECTIVES This report presents the revised growth charts for the United States. It summarizes the history of the 1977 National Center for Health Statistics (NCHS) growth charts, reasons for the revision, data sources and statistical procedures used, and major features of the revised charts. METHODS Data from five national health examination surveys(More)
OBJECTIVE To present a clinical version of the 2000 Centers for Disease Control and Prevention (CDC) growth charts and to compare them with the previous version, the 1977 National Center for Health Statistics (NCHS) growth charts. METHODS The 2000 CDC percentile curves were developed in 2 stages. In the first stage, the empirical percentiles were smoothed(More)
BACKGROUND Body composition estimates for the US population are important in order to analyze trends in obesity, sarcopenia and other weight-related health conditions. National body composition estimates have not previously been available. OBJECTIVE To use transformed bioelectrical impedance analysis (BIA) data in sex-specific, multicomponent(More)
BACKGROUND The Centers for Disease Control and Prevention (CDC) introduced the clinical use of the body mass index (BMI; in kg/m(2)) in growth charts for young males and females. OBJECTIVE This study updates our previous report with the use of new CDC BMI charts and definitions of adult overweight and obesity to predict adult overweight or obesity. (More)
BACKGROUND Changes in body composition in men and women occur with age, but these changes are affected by numerous covariate factors. OBJECTIVE The study examined patterns of change in body composition and determined the effects of long-term patterns of change in physical activity in older men and women and in menopausal status and estrogen use in women.(More)
OBJECTIVE To compare 16 currently used total body fat methods to a six-compartment criterion model based on in vivo neutron activation analysis. DESIGN Observational, inter-method comparison study. SUBJECTS Twenty-three healthy subjects (17 male and 6 female). MEASUREMENTS Total body water (TBW) was measured by tritium dilution; body volume by(More)
Body mass index (BMI; in kg/m2) values at or above the 75th percentile are associated with increased morbidity and mortality in adulthood, and there are significant correlations between BMI values in childhood and in adulthood. The present study addresses the predictive value of childhood BMI for overweight at 35 ± 5 y, defined as BMI > 28 for men and BMI >(More)
We examined patterns of change in body composition from 8 to 20 yrs of age and the effects of rate of maturation on these patterns using serial data for total body fat (TBF). There is a continual increase, but a declining rate of change with age in TBF. For %BF the same pattern as for TBF exists for females, but for males the pattern of change in percentage(More)
OBJECTIVE The aim is to describe body composition in relation to body mass index (BMI; body weight/stature(2)) to provide health care professionals insight into the meaning, significance, and limitations of BMI as an index of adiposity during childhood. METHODS Data from 387 healthy, white children 8 to 18 years of age from the Fels Longitudinal Study(More)
