  This study investigated the effect of a macrobiotic (vegan‐type) diet, low in calcium and vitamin D, consumed in early life, on bone mineral during adolescence. Bone mineral content (BMC) and bone area were measured in adolescents ( girls, 92 boys) aged 9–15 years, using dual‐energy X‐ray absorptiometry.   Bone histomorphometry: proposed system for standardization of nomenclature, symbols, and units.

Clinical and anthropometric correlates of bone mineral acquisition in healthy adolescent girls.

During adolescent period WBMC were increased times in male and times in female. Whole body BMD (WBMD) was lowest at 10 years ( g/cm 2 in male and g/cm 2 in female) and highest at 19 years ( g/cm 2 in male and g/cm 2 in female). Background: Adults with celiac disease (CeD) show low bone mineral density (BMD) and high fracture risk. CeD guidelines suggest measurements of serum minerals and vitamin D. However, studies on vitamin levels in CeD patients are contradictory. Aim: To investigate in CeD, hydroxy-vitamin D [25(OH)D], 1,dihydroxy-vitamin D [1,25(OH)2D], and related analytes .

Background: Decreased bone mineral density (BMD) is a concern in patients with congenital adrenal hyperplasia (CAH) due to lifelong glucocorticoid replacement. Studies till date have yielded conflicting results. We wanted to systematically evaluate the available evidence regarding BMD in adult patients with s: We searched Medline, Embase and Cochrane . Revised reference curves for bone mineral content and areal bone mineral density according to age and sex for black and non-black children: results of the bone mineral density in childhood study.

Kalkwarf et al. () concerned with determining bone mass in children and adolescents between 6 and 16 years of age, identified that the lack of bone mineral gain in this stage of life is linked to microarchitecture disruption during senility.

They evaluated bone mineral density in Americans from different geographical locations, using Cited by:   Clinical Cases in Mineral and Bone Metabolism; 5(1): ; Karaguzel, G, Holick, M. Diagnosis and treatment of osteopenia. Reviews in Endocrine and Metabolic Disorder.

The amount of skeletal mass acquired during adolescence is one of the most important factors in determining the risk of osteoporosis and fractures later in healthy females, about 40% of peak bone mass is accumulated during the adolescent average, young women attain 92% of their total body bone mineral content (BMC) by age 18 Cited by:   Aim: To evaluate the relationships of visfatin, adiponectin and leptin with bone mineral density (BMD) and bone mineral content (BMC) in adolescent female athletes with different training patterns.

Methods: This study involved healthy 13–15‐year‐old girls divided into six groups based on activity: sport games (i.e. basketball, volleyball, badminton) (n = 49), Cited by: Concerns about bone health and potential fragility in children and adolescents have led to a high interest in bone densitometry.

Pediatric patients with genetic and acquired chronic diseases, immobility, and inadequate nutrition may fail to achieve expected gains in bone size, mass, and strength, leaving them vulnerable to fracture.

In older adults, bone densitometry has been. INTRODUCTION. Adolescence is a crucial period for skeletal development. Because of the dramatic effects of puberty on bone growth and consolidation, there is up to a 50% increase in total body bone mass between the ages of 12 and 18 years ().Because sex hormones play a key role Correlates of bone mineral density in adolescence book bone mass accrual we were interested in the effects of hormonal contraception on bone in the growing adolescent.

AIM To examine early factors in bone mineral accretion in cystic fibrosis (CF). METHODS In 22 prepubertal children with CF and mild lung disease, the relation between total body bone mineral density (BMD) and measures of body composition, biochemistry, lung function, and physical activity was studied.

RESULTS There was a non-significant mild reduction in mean total body. Ho-Pham LT, Nguyen PL, Le TT, et al. Veganism, bone mineral density, and body composition: a study in Buddhist nuns.

Large quantities of alcohol consumed by young rats resulted in weaker bones (Sampson, Perks, Champney, and DeFee, ). These findings from animal models are supported by studies in humans showing that alcohol drinkers tend to have less bone mineral density, especially adolescent males (Neville et al., ).

Long term calcium deficiency during adolescence leads to poor bone mineral accrual in and early onset of osteoporosis. Information on calcium intake was obtained by 24hour recall method for three days. BMD of the whole body was measured by using dual-energy X-ray absorptiometry (DEXA).

Mean calcium intake among % of the subjects ( out of ). Abstract. The authors performed a study of bone mass in eutrophic Brazilian children and adolescents using dual-energy X-ray absorptiometry (DXA) in order to obtain curves for bone mineral content (BMC) and bone mineral density (BMD) by chronological age and correlate these values with weight and height.

Since bone size increases during adolescence, we present a new expression, bone mineral apparent density (BMAD), which is BMC normalized to a derived bone reference volume. This term minimizes the effect of bone geometry and allows comparisons of mineral status among bones of similar shape but different size.

BMC increased with age at all sites. Bone density, or bone mineral density (BMD), is the amount of bone mineral in bone concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

Bone density measurement is used in clinical. Increase in bone mass during adolescence results from increases in bone length, bone diameter, cortical bone width, and cancellous bone density.

Smoking and alcohol consumption during adolescence and early adult life may have an adverse effect on peak bone mass. Adolescent female athletes are at increased risk for low bone mineral density (BMD) secondary to exercise-induced hypogonadism. Of particular concern is that the adolescent years are also a critical time for bone accrual, and deficits incurred during this period could lead to suboptimal peak bone mass acquisition and subsequent fracture risk in lat.

Objectives: Bone health is affected in TypeDiabetis (T1D) causing higher risk of hip fractures, prolonged fracture healing and altered bone mineral density (BMD).

In T1D adults BMD is found to be decreased. In this study we have measured the BMD in children and adolescents from the Copenhagen Pediatric T1D Cohort.

ISNI: Awarding Body: University of Ulster Current Institution: Ulster University Date of Award: Bone Density Basics– what is it and why is it important – no matter what your age The first DEXA, was built in for commercial use.

DEXA is used all over the world for both body composition and determining bone mineral density (BMD). Bone Mineral Density and Fracture Risk. Bone mass or BMD refers to the amount of mineral matter per volume of bones and directly correlates with bone strength mineral density is influenced by many factors, including, gender, age, race, body mass index, hereditary factors, physical stress on bones related to physical activity and weight bearing, nutritional factors.

Vegetarian diets are associated with factors that may not support bone health, such as low body mass and low intakes of protein; yet, these diets are alkaline, a factor that favors bone mineral density (BMD). This study compared the correlates of BMD in young, non-obese adults consuming meat-based (n = 27), lacto-ovo vegetarian (n = 27), or vegan (n = 28) diets for ≥1.

Bone mineral density (BMD) was significantly lower (by 5% to 10%) in HIV-positive than negative men at the femoral neck, total hip, distal radius, and ultra distal radius--and nonsignificantly lower at the lumbar spine (P = ).Lean body mass (LM) has been positively associated with bone mineral density (BMD) in children and adolescents, but the relationship between body fat mass (FM) and BMD remains controversial.

Several biomarkers secreted by adipose tissue, skeletal muscle, or bone may affect bone metabolism and BMD.
