Weight estimation among multi-racial/ethnic infants and children aged 0–5·9 years in the USA
Objective In resource-constrained facilities or during resuscitation, immediate paediatric weight estimation remains a fundamental challenge. We aimed to develop and validate weight estimation models based on ulna length and forearm width and circumference measured by simple and portable tools; and to compare them against previous methods (advanced paediatric life support (APLS), Theron and Traub–Johnson formulas). Design Cross-sectional analysis…
Longer breastfeeding duration reduces the positive relationships among gestational weight gain, birth weight and childhood anthropometrics
BACKGROUND: The relationship between gestational weight gain (GWG) and childhood growth remains controversial. An examination on whether infant feeding practices mediate this relationship may improve our understanding of it. METHODS: We investigated whether the relationships among GWG, birth weight and childhood anthropometrics were mediated through infant feeding practices (breastfeeding duration and age at introduction of solid foods) in a cros…

Reliability of anthropometric methods and replicate measurements
The Spearman‐Brown Prophesy formula, derived from psychometrics, may be used in anthropometric studies to describe the relationship between the intraclass reliability coefficient for a single measurement and the reliability resulting from the mean of replicate measurements. This theory may be applied to determine expected reliabilities of anthropometric protocols using replicate measurements and to determine the numbers of replicate measurements …
Reported versus measured adult statures
Reported and measured statures were obtained for 100 husband‐wife pairs. In addition, wives were asked to specify whether their husbands were tall, medium, or short. Correlations between reported and measured statures are high (0.84–0.97) and wives tend to overestimate their own measured stature by about 1 cm, and that of their husbands by about 1.3 cm. Wives correctly classify their husbands as tall, medium, or short in about 70% of the cases, u…
Science, Nutrition, Fat, and Policy
Supplementation of the diets of pregnant and nursing mothers in underdeveloped countries is sometimes criticized because more food for these women is seen as producing more body fat, shortened postpartum amenorrhea, and increased fertility. We argue that the link between body fat and shortened postpartum amenorrhea is based on a hypothesis that has not been corroborated. The critical-fat hypothesis is that menarche, maintenance of menstrual cycle…

Sexual dimorphism in bone growth as a function of body size in moderately malnourished Guatemalan preschool age children
The sexual dimorphism in second metacarpal bone growth was investigated in 710 malnourished Guatemalan children one to seven years old to determine if the sex differences seen are only the result of differences in stature and weight. The study sample was mixed‐longitudinal and consisted of 1,586 annual examinations. Boys have greater mean stature, weight, periosteal diameter, medullary diameter and cortical area than girls the same age, while gir…
Longer breastfeeding duration reduces the positive relationships among gestational weight gain, birth weight and childhood anthropometrics
BACKGROUND: The relationship between gestational weight gain (GWG) and childhood growth remains controversial. An examination on whether infant feeding practices mediate this relationship may improve our understanding of it. METHODS: We investigated whether the relationships among GWG, birth weight and childhood anthropometrics were mediated through infant feeding practices (breastfeeding duration and age at introduction of solid foods) in a cros…

An early hand-wrist atlas and its implications for secular change in bone age
A little-known 'Skiagraphic Atlas' documenting radiographic changes in the bones of the hand and wrist was published by Poland in 1898. Nineteen skiagrams of British children, 1-17 years of age, were included. Tanner-Whitehouse-2 bone ages were assessed for 15 individuals in this series and differences from chronological ages were calculated. Mean differences for 20-bone, RUS and carpal bone ages are significantly larger than zero. Hence, these c…

Resistant cross‐ age smoothing of age‐specific percentiles for growth reference data
Resistant delineation, a technique adapted from exploratory data analysis (Tukey, Exploratory Data Analysis, 1977), was applied to smooth age‐specific percentiles for triceps skinfold thickness across ages from 1 to 20 years. Row percentiles were transformed to logarithms to promote symmetry and to render variability more nearly homogeneous across ages. The delineation involved smoothing resistantly the sequences of age‐specific log medians and t…

Measurement errors for a portable device measuring short‐term growth
A field trial was conducted for a portable Knee Height Measuring Device (KHMD). Measurement errors for the machine, within and between observers (intraobserver and interobserver) and within subjects (intrasubject), were calculated from repeated observations of two anthropometrists on 40 children, 8 and 9 years of age. Interobserver technical error (0.452 mm) was larger than that published by the KHMD developers, but intraclass reliabilities are s…
Menarcheal status and bone development in Guatemalan girls
Premenarcheal and postmenarcheal girls of the same chronological ages (11.5–15.5 years) and from the same villages in Guatemala differ significantly in patterns and mean levels of several measures of bone development. Stature, metacarpal dimensions, bone mineral content and bone mineral density from single photon absorptiometry, and total alkaline phosphatase activity are significantly associated with menarcheal status. Controlling for chronologi…
Serum alkaline phosphatase activity and skeletal maturation in Guatemalan adolescents
Serum alkaline phosphatase activity (AP), stature and Tanner-Whitehouse-2 RUS skeletal age (SA) were determined for 873 rural Guatemalan youth and young adults 11-25 years of age. Mean AP decreases systematically with chronological age (CA) in girls, while an adolescent increase in mean AP occurs at 14 years in boys. When mean AP is calculated within SA groups, clear adolescent increases are apparent in girls, peaking at 11 years SA, and at 14 ye…
