Racial differences in skeletal calcium retention in adolescent girls with varied controlled calcium intakes1,2,3
Black persons white persons skeletal calcium dietary calcium adolescents
2008/12/11
Background: Higher bone mass in blacks than in whites has been related to greater calcium utilization efficiency. Dietary calcium requirements for maximal skeletal calcium accretion during puberty may...
Total body protein in healthy adolescent girls: validation of estimates derived from simpler measures with neutron activation analysis1,2,3
Body composition adolescents total body protein total body nitrogen fat-free mass neutron activation analysis
2008/12/9
Background: Little recent and accurate information about body protein content in healthy adolescent girls is available. Objective: The objective was to assess the total body nitrogen (TBN) and total b...
Postnatal weight and height growth velocities at different ages between birth and 5 y and body composition in adolescent boys and girls
body composition adolescent boys
2016/12/30
Anthropometric measures, including fat and fat-free mass by bipodal impedancemetry, were measured in 468 adolescents aged 8–17 y. We retrospectively collected early infancy data and individually estim...
Effect of a calcium and exercise intervention on the bone mineral status of 16–18-y-old adolescent girls
dietary calcium exercise intervention osteoporosis
2016/12/30
We conducted a 15.5-mo study of calcium supplementation (1000 mg Ca/d as carbonate) in 144 adolescent girls aged 17.3 ± 0.3 y (x̄ ± SD). The subjects were randomly allocated to an exercise (three...
Predictors of body fat gain in nonobese girls with a familial predisposition to obesity
Obesity children energy expenditure
2017/1/5
We determined the effect of energy expenditure (EE), muscle energetics, and physical fitness on weight and fat gain in prepubertal girls with or without a predisposition to obesity.
Association of low 25-hydroxyvitamin D concentrations with elevated parathyroid hormone concentrations and low cortical bone density in early pubertal and prepubertal Finnish girls
cortical bone density biomarkers prepubertal girls
2017/1/4
We studied the associations of serum 25(OH)D and intact PTH (iPTH) with bone mineral content (BMC) and bone mineral density (BMD) at different bone sites and the relation between serum 25(OH)D and iPT...
Longitudinal changes in the accuracy of reported energy intake in girls 10–15 y of age
Energy intake energy expenditure adolescents
2017/1/4
Dietary records are often used to estimate individual energy needs and population energy requirements. However, significant underreporting of total energy intake (EI) has been found when EI is compare...
Learning to overeat: maternal use of restrictive feeding practices promotes girls’ eating in the absence of hunger
Eating in the absence of hunger overeating restrictive feeding practices
2017/1/3
Experimental findings causally link restrictive child-feeding practices to overeating in children. However, longitudinal data are needed to determine the extent to which restrictive feeding practices ...
Efficiency of calcium absorption is not compromised in clinically stable prepubertal and pubertal girls with cystic fibrosis
bone calcium stable isotopes
2017/1/3
Reduced bone mass is common in both children and adults with cystic fibrosis (CF) and may be a consequence of inadequate calcium absorption. The effect of CF on intestinal calcium absorption and reten...
Vitamin D and attainment of peak bone mass among peripubertal Finnish girls:a 3-y prospective study
Adolescence peripubertal girls bone mineral density bone mineral apparent density serum 25-hydroxyvitamin D bone mass Finland
2016/12/20
Background: Little is known about the effect of vitamin D status on bone gain in adolescents.Objective: The objective was to examine whether vitamin D status is associated with accrual of bo...
Relation of body composition,parental overweight,pubertal stage,and race-ethnicity to energy expenditure among premenarcheal girls
malnutrition energy metabolism oxidative phosphorylation respiratory chain hypoenergetic feeding complex activity rats
2016/12/19
Background: Previous studies assessed the influence of parental weight status, sexual maturation, race-ethnicity, and energy expenditure among children, but few examined these issues comprehensiv...
