Peak Bone Mass, Lifestyle Factors and Birth Weight: A study of 25-year old women
Background: Osteoporosis is a common bone disease, which does not give symptoms until the ultimate outcome, the fragility fracture occurs. Regulation of bone mass is controlled by genetic, environmental and nutritional influences. Peak bone mass, defined as the maximum bone mass accrued, is usually …

Dietary calcium: Effect of bioavailability and level of intake on bone growth, development and maintenance in the rat
… to determine the effect of calcium intake on bone growth, development and maintenance using the rat as a model. The central hypotheses that were tested were: (I) dietary calcium provided from a low bioavailable source will compromise both bone quality and bone quantity in the young and old …

The relationship between body composition and bone in preadolescent children
The importance of optimizing peak bone mass early in life for the prevention of fractures throughout the lifespan and more debilitating diseases such as osteoporosis is well known today. However, more research is necessary to understand the importance of various determinants of bone health in …

Novel Molecules that Regulate Bone Formation and Bone Resorption
… is a disease characterized by decreased bone mass and microarchitectural deterioration of bone. Bone loss occurs when the increased bone resorption that occurs with age is not compensated by a corresponding increase in bone formation. Therefore, understanding the mechanisms which regulate …

Estimating Body Mass through Bone Mineral Density Studies Using Dexa (Dual-Energy X-Ray Absorptiometry)
… of information that could be beneficial is body mass. The goal of this research is to explore the relationship between bone mineral density (BMD) and body mass, using data collected from dual x-ray absorptiometry (DEXA) scans of 107 collegiate football athletes. Athletes are a good fit for this …

Nutrient intake and Urine and Serum Calcium Response to a low Calcium Diet and Repletion
… intake of calcium (Ca) in the years when peak bone mass is being formed may have a detrimental impact on bone later in life. This study looked at the effect of low Ca intake and other dietary components on serum and urine values of Ca as well as the response to repletion.</p> <p>Seventeen …

Dietary Intake and Bone Mineral Density in Young-Adult Females
… third decades of life are critical periods for bone health due to the attainment of peak bone mass during this time, yet little is known about relationships between lifestyle factors and bone health among young-adult females. Therefore, anthropometric, body composition, and nutritional variables …

Characterizing Femoral Structure of the Ts66Yah Mouse Model of Down Syndrome
… can result in skeletal deficits, including lower bone mineral density (BMD) and increased risk of fracture and osteoporosis or osteopenia earlier than the general population. Mouse models of DS have been developed to understand the genetic mechanisms resulting in these phenotypes, but models …

Bone Mineral Density and Biomarkers of Bone Turnover in Young-Adult Females with and without Cognitive Eating Restraint
… the final window of opportunity to maximize peak bone mass and help prevent osteoporosis later in life. Dietary habits of young women are often molded by social pressures to be thin. Negative implications for cognitive eating restraint (CER) on bone health have been shown, but direct evidence …

Bone Mass from Childhood to Adulthood
Attaining high peak bone mass (PBM), the highest bone mass value in life which is reached in young adulthood, is important as it reduces the risk of having low bone mass in old age69, 80. Low bone mass is associated with high fracture risk3, 60. Osteoporosis is the result of bone loss, a …

Determinants Of Bone Mineral Density In African-American And Caucasian College-Aged Women
… rate when compared to Caucasians with the same bone mineral density (BMD). However, when African-American women do fracture, they have higher mortality and morbidity rates. Data regarding risk factors and prevalence of low BMD among African American and Caucasian college-aged women are limited. …

Differences in Bone Mineral Density Among Adolescent Female Tennis Players and Non-Tennis Players
… and is one of the major determinants of peak bone mass during adolescence. However, type of pa plays an important role when examining the effects of pa on bone mineral density (BMD). Purpose: 1) to determine the differences in BMD among adolescent female tennis players (TP) and non-tennis …

The impact of food and nutrient intake on bone from childhood to early adulthood
Development of peak bone mass during childhood to early adulthood has been considered as a major determinate of risk of fracture and osteoporosis later in life. The purpose of this project was to determine the impact of food and nutrient intake on bone from childhood to early adulthood using mixed …

Influence of Oral Contraceptives on Bone Adaptations to Isokinetic Strength Training in Young Women
… disease of the skeleton characterized by low bone mass and structural deterioration of bone tissue leading to bone fragility and an increased susceptibility to fractures of the hip, spine, and wrist. Current data suggest that at present time, 7.8 and 21.8 million women have osteoporosis and …

Bone Mineral Density, Preventative Behaviors And Risk Factors In African American And Caucasian Mother-Daughter Pairs
… have osteoporosis and an estimated 35% have low bone mass (nof, n.d.). It is estimated that while over 40% of African American women over 80 years meet criteria for treatment, yet less than 12% are actually treated (Cauley, 2011). Striking disparities exist between African American and Caucasian …

Bone strength in early childhood : Associations with vitamin D and motor development
Bone health during childhood has gained attention, as early bone mass accrual significantly influences skeletal health in adulthood. Higher peak bone mass achieved in early life is considered protective against osteoporosis and fractures later in life. Various factors, including genetics, diet, …

IDENTIFICATION OF MECHANISMS OF DELAYED PUBERTY ON BONE STRENGTH DEFICITS DURING DEVELOPMENT
… (Golden, 2000) can result from a lack of optimal bone accrual during the development (NIH Consensus Development Panel on Osteoporosis Prevention, Diagnosis, and Therapy, 2001). Pubertal timing is a key factor that contributes to optimal bone accrual and strength (Bonjour et al., 1994; 21 Warren et …

Physical activity and its effect on bone in the short- and long- term perspective.
… thought to be an opportune time to build strong bones and the enhancement of peak bone mass (PBM) has been suggested as a prevention strategy for osteoporosis. Most exercise intervention studies in children, evaluating the accrual of areal bone mineral density (aBMD), include volunteers and use …
