Presentation, Heritability, and Genome-Wide Linkage Analysis the Midchildhood Growth Spurt in Healthy Children from the Fels Longitudinal Study
Growth is a complex process composed of distinct phases over the course of childhood. Although the pubertal growth spurt has received the most attention from auxologists and pediatricians, the midchildhood growth spurt has been less well studied. The midchildhood growth spurt refers to a relatively small increase in growth velocity observed in some, but not necessarily all, children in early to middle childhood. If present, the midchildhood growt…

Genetic Architecture of Knee Radiographic Joint Space in Healthy Young Adults
Evidence of a significant genetic component to the age-related degenerative joint disease osteoarthritis has been established, but the nature of genetic influences on normal joint morphology in healthy individuals remains unclear. Following up on our previous findings on the influence of body habitus on phenotypic variation in knee joint space [Duren et al., Human Biology 78:353–364 (2006)], the objective of the current study was to estimate the …
Age at Menarche and Racial Comparisons in US Girls
Background. Concern regarding change in the onset of sexual maturation of US girls has increased the need for current information on age at menarche from a national sample. Previous reports have been sparse and interpretation has been limited because of the racial composition and ages of the samples. Objective. The objectives of this study were to estimate the distribution of age at menarche for all US girls and for non-Hispanic white, black, and…
Predicting overweight and obesity in adulthood from body mass index values in childhood and adolescence
Tracking of body mass index in children in relation to overweight in adulthood
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 >26 for women. Analyses of data from 555 white children showed that overweight at age 35 y …
Changes in anthropometric indices of body composition with age in a healthy elderly population
Changes in body composition are known to occur with old age, but there is limited knowledge of the normal values rates of change in anthropometric indices of body composition or the distribution of these changes in the elderly. In the present study, 98 elderly white men and 122 elderly white women were followed prospectively for 6 years. These participants were divided into 5-years cohorts on the basis of age at the start of the study in 1980. Se…
Ultrasonic and skinfold caliper measures of subcutaneous adipose tissue thickness in elderly men and women
Ultrasonic and skinfold caliper measures of subcutaneous adipose tissue were taken in a sample of elderly men and women, 65 to 99 years of age with an A‐mode Ithaco Body Composition Meter and a Holtain skinfold caliper. For most of the measurements, standard deviations for the ultrasonic measurements were three or more times larger than corresponding caliper measurements. Also, mean absolute interobserver errors for the ultrasonic measurements we…
Accuracy and reliability of a new sliding caliper
There are several types of sliding calipers, but most are expensive and not capable of measuring large body dimensions such as arm length or knee height in older children and adults. A new sliding caliper from Medi‐form can accurately measure lengths from 0.0 to 80.0 cm. This caliper is slightly more accurate than a Holtain sliding caliper, and its cost is low
A comparison of methods for measuring cortical bone thickness
Repeated measures of periosteal and endosteal widths of the left second metacarpal from two samples of radiographs were made independently with either a dial caliper or an electronic digitizer connected to a microcomputer. In addition, periosteal and endosteal bone widths of a common sample of radiographs were measured with dial calipers and the electronic digitizer. Dial calipers and an electronic digitizer are both very reliable, but intraobser…
