“…Consequently, it seems very important to determine the physiological factors that are related to bone mass and density in this period of life. Several authors have suggested that LM was the best predictor of BMD in children and adolescents (Courteix et al 2007;Vincente-Rodriguez et al 2003, 2004Witzke and Snow 1999). Interestingly, this relation between BMD and LM was found to be stronger in trained children and adolescents than in non-trained ones (Vincente-Rodriguez et al 2003, 2004.…”

The aim of this study was to determine the relative importance of lean mass (LM) and fat mass (FM) on bone mineral density (BMD) in a group of adolescent girls and boys. A total of 65 adolescent boys and 35 adolescent girls participated in this study. Whole body (WB) and lumbar spine (L1-L4) BMD were measured by dual-energy X-ray absorptiometry (DXA). Body composition was assessed using the same technique. In boys, LM was strongly related to WBBMD (r = 0.68; p < 0.001) and to L1-L4 BMD (r = 0.61; p < 0.001), whereas FM was not positively related to BMD and was negatively associated with WB bone mineral apparent density (WBBMAD). In girls, both LM and FM were positively related to WBBMD (r = 0.41; p < 0.05 and r = 0.49; p < 0.01, respectively), whereas only FM was correlated to L1-L4 BMD (r = 0.33; p < 0.05). Finally, in a multiple regression analysis, FM was found to be a better positive determinant of WBBMD than LM in girls, whereas in boys, FM was found to be a negative determinant of WBBMD and L1-L4 BMD. This study suggests that LM is a strong determinant of WBBMD and L1-L4 BMD in boys, and that FM is a stronger determinant of WBBMD than LM in girls.

“…In a prospective cohort study, older men with low serum 25-hydroxyvitamin D had greater rates of hip bone loss [37]. Exercise, particularly weight-bearing activities, improved bone mass in childhood and adolescents [38,39], but the effects of exercise on bone mass in middle-aged and older men are controversial. High-intensity training in men aged 50-60 years resulted in a significant increase in lumbar spine and trochanter BMD [40].…”

Background/Aims: Studies on determinants of bone mineral density (BMD) among Asian middle-aged and older men are very limited. The aim of this study was to investigate general determinants and dietary factors influencing BMD in Korean middle-aged and older men. Methods: This study was conducted using data from the 2008-2010 Korea National Health and Nutrition Examination Survey. A total of 2,305 male subjects aged 50-79 years were included. Whole-body, total femur, femoral neck, and lumbar spine BMDs were measured by dual-energy X-ray absorptiometry. Dietary intake was estimated by 24-hour dietary recall. A food frequency questionnaire for 63 food items was also administered. Results: Proportions of osteoporosis at the total femur, femoral neck, and lumbar spine were 0.7, 3.3 and 7.0%, respectively. Age, height, weight, body mass index, fat mass, lean body mass, waist circumference, serum vitamin D, parathyroid hormone, and exercise were related to BMD, but the relationships were site specific. Diet quality and intake of vegetables, fruits, and calcium were associated with BMD. Conclusions: These results suggest that a high-quality diet, an adequate intake of fruits, vegetables, and calcium, as well as exercise, high serum vitamin D and weight maintenance might be determinants of BMD among middle-aged and older Asian men.

“…However, Slemenda et al [40] found that pubertal development has varying effects on skeletal mineral deposition depending on the skeletal site considered. Other factors such as physical activity and normal growth have also been positively associated with skeletal mineralization [34,42,43], and also depending on skeletal site and sexual maturation. Our analyses were grouped into 2 categories (Tanner ≤IV and Tanner V) in order to obtain a higher sample in the first group, and were then not comparable with those of Slemenda et al [40].…”

Background/Aims: The assessment of bone mineral content (BMC) and density (BMD) status in children and adolescents is important for health and the prevention of diseases. Bone metabolic activity could provide early information on bone mass development. Our aim was to describe bone mass and metabolism markers according to age and Tanner stage in adolescents. Methods: Spanish adolescents (n = 345; 168 males and 177 females) aged 12.5–17.5 years participated in this cross-sectional study. Body composition variables were measured by dual-energy X-ray absorptiometry. Serum osteocalcin (n = 101), aminoterminal propeptide of type I procollagen (n = 92) and β-isomerized C-telopeptides (β-CTX, n = 65) and urine samples (β-CTX; n = 237) were analyzed by electrochemiluminescence immunoassay. Results: Analysis of covariance showed that females had higher values for BMC and BMD in most of the regions. Both males and females had a significant decrease in bone markers while sexual maturation increases (all p < 0.05). Males had an increased bone turnover compared to females (all p < 0.05, except for urine β-CTX in Tanner ≤IV). Conclusion: Our results support the evidence of dimorphic site-specific bone accretion between sexes and show an increased bone turnover in males, suggesting higher metabolic activity.
