The Impact

Abstract Bone health is extremely important in early childhood because children with low bone mineral density (BMD) are at a greater risk of bone fractures. While physical activity and intake of both calcium and vitamin D benefit BMD in older children, there is limited research on the determinants of good bone health in early childhood. The aim of this cross-sectional study was to investigate the impact of diet, physical activity, and body composition on BMD at five years of age. Dietary intakes and physical activity levels were measured through questionnaires. Whole body BMD was measured by dual-energy X-ray absorptiometry in 102 children. Child weight, height, circumferences, skinfolds and serum 25-hydroxyvitamin D (25OHD) concentrations were assessed. There was no association between BMD and dietary calcium, dietary vitamin D, 25OHD, physical activity, or sedentary behaviour. Several measures of body composition were significantly positively associated with BMD; however, neither fat mass nor lean body mass was associated with BMD. Conclusion: Although we found no association between self-reported dietary and lifestyle factors and bone health in early years, increased body size was linked with higher BMD. These findings are important as identifying modifiable factors that can improve bone health at a young age is of utmost importance.What is Known:• Bone health is extremely important in early childhood, as children with low bone mineral density (BMD) are at greater risk of bone fractures.• Physical activity has been found to be beneficial for bone health in adolescents, and body composition has also been associated with BMD in teenage years.• Limited research on the determinants of good bone health in early childhood.What is New:• No association between self-reported lifestyle and dietary factors with bone health in early childhood.• Increased body size was associated with higher BMD at five years of age.

Abstract Summary The aim of the study was to assess the associations of bone mineral density and bone mass with physical activity levels, vitamin D, phosphorus, magnesium, total cholesterol and triglyceride concentration and body composition in young women and men. Physical activity has the most significant effect on bone status especially in men. Purpose The aim of the study was to assess the associations of bone mineral density and bone mass with physical activity levels, vitamin D, phosphorus, magnesium, total cholesterol and triglyceride concentration and body composition in young women and men. Methods One hundred subjects aged 19–24 years were included. Bone mineral density (BMD) in distal and proximal parts was evaluated by forearm densitometry. Body composition was analysed with the use of JAWON-Medical-x-scan. The following biochemical indicators were analysed: 25(OH) D and 1,25(OH)2D, magnesium, phosphorus, total cholesterol and triglycerides. Physical activity levels were assessed by interview. Results Significant correlations between BMD and physical activity, skeletal muscle mass and body fat percentage were revealed in men. Among women, considerably weaker correlations of BMD with body composition and physical activity were noted than in men. BMD in the distal part correlated only with lean body mass, soft lean mass and body fat percentage. The strongest relationship between physical activity and bone mineral status parameters was noted for BMD in men. In women, physical activity did not affect BMD. Conclusions Physical activity has the most significant effect on bone status especially in men.

Viable Method

Vitamin K is essential to the body because it is known to help blood coagulate and activate osteocalcin, a protein involved in maintaining healthy bones. In this review, one study observing the impact of vitamin K supplementation on patients’ bone mineral densities and three studies focusing on the effects of vitamin K supplementation on the incidence of bone fractures are discussed to determine whether the vitamin may be important for maintaining bone health. While some promising results, such as an increase in bone mineral density of subjects after vitamin K supplementation arose, the conclusions reached by the four studies were not statistically significant enough to justify the importance of vitamin K in maintaining bone health. Well-controlled studies that are unbiased, statistically powerful, and focused on vitamin K’s effects on bone density are required in the future to provide further insight on whether vitamin K supplementation is a viable method of improving bone health. La vitamine K est essentielle pour le corps, car il est connu pour assister dans la coagulation du sang ainsi qu’activer l'ostéocalcine, une protéine impliquée dans le maintien de la santé des os. Ici, une étude dirigé vers les observations de l'impact de la consommation de suppléments de la vitamine K sur la densité minérale osseuse de patients, puis trois autres études portant sur les effets de la consommation de suppléments de la vitamine K sur l'incidence des fractures osseuses sont examinées afin de déterminer si la vitamine soit une facteur important dans le maintien de la santé des os. Tandis que des résultats sont révélés prometteurs, comme ceux montrant une augmentation de la densité minérale osseuse des sujets après la consommation des suppléments de la vitamine K, l’ensemble de conclusions tirées des quatre études ne présente pas suffisamment de données qui pourraient suggérer une corrélation entre la consommation des suppléments de la vitamine K et la santé des os. Des études supplémentaires portant sur les effets de la vitamine K sur la densité osseuse, mené dans des conditions contrôlés, bien conçus, impartiales, qui produiront des résultats persuasifs, sont nécessaires à être effectuer à l'avenir afin de donner un meilleur aperçu de l’effet de la supplémentation en vitamine K comme une méthode viable dans l’entretien de la santé des os.

Abstract Background: Modifiable lifestyle factors and body composition can affect the attainment of peak bone mass during childhood. This study performed a cross-sectional analysis of the determinants of bone health among pre-adolescent Malaysian children with habitually low calcium intakes and vitamin D status in Kuala Lumpur (PREBONE-Kids Study). Methods: Body composition, bone mineral density (BMD), and bone mineral content (BMC) at the lumbar spine (LS) and total body (TB) were assessed using dual-energy X-ray absorptiometry (DXA). Calcium intake was assessed using 1-week diet history, MET (metabolic equivalent of task) score using cPAQ questionnaire, and serum 25(OH) vitamin D using LC-MS/MS. Results: The mean calcium intake was 348.8 ± 180.1 mg/day and mean serum 25-OH vitamin D level was 43.9 ± 14.5nmol/L. In boys, lean mass (LM) was significantly associated with LSBMC (β = 0.539, p<0.001), LSBMD (β=0.607, p<0.001), TBBMC (β=0.675, p<0.001) and TBBMD (β= 0.481, p<0.01). Height was significantly associated with LSBMC (β =0.346, p<0.001) and TBBMC (β =0.282, p<0.001) while fat mass (FM) (β=0.261, p=0.034) and MET score (β =0.163, p=0.026) were significant predictors of TBBMD. Among girls, LM was significantly associated with LSBMC (β = 0.620, p<0.001), LSBMD (β=0.700, p<0.001), TBBMC (β=0.542, p<0.001) and TBBMD (β= 0.747, p<0.001). Calcium intake was a significant predictor of LSBMC (β=0.102, p=0.034), TBBMC (β=0.122, p<0.001) and TBBMD (β=0.196, p=0.002) in girls. Lean mass (LM) was weakly correlated with MET scores (r = 0.205, p = 0.001) but not protein (r = 0.055, p = 0.393) or energy intake (r = 0.101, p = 0.117). MET score (β = 0.207, p = 0.043) was a significant predictor of LM in boys but no factor was found to predict LM in girls. Conclusion: LM is the major determinant of BMC and BMD among pre-adolescent Malaysian children and physical activity is a significant predictor of LM in boys. Encouraging physical activity, calcium intake and optimum diets that build lean body mass should be the focus for developing public health guidance to ensure optimal bone health status during rapid growth.

Abstract Background Modifiable lifestyle factors and body composition can affect the attainment of peak bone mass during childhood. This study performed a cross-sectional analysis of the determinants of bone health among pre-adolescent (N = 243) Malaysian children with habitually low calcium intakes and vitamin D status in Kuala Lumpur (PREBONE-Kids Study). Methods Body composition, bone mineral density (BMD), and bone mineral content (BMC) at the lumbar spine (LS) and total body (TB) were assessed using dual-energy X-ray absorptiometry (DXA). Calcium intake was assessed using 1-week diet history, MET (metabolic equivalent of task) score using cPAQ physical activity questionnaire, and serum 25(OH) vitamin D using LC-MS/MS. Results The mean calcium intake was 349 ± 180 mg/day and mean serum 25(OH)D level was 43.9 ± 14.5 nmol/L. In boys, lean mass (LM) was a significant predictor of LSBMC (β = 0.539, p < 0.001), LSBMD (β = 0.607, p < 0.001), TBBMC (β = 0.675, p < 0.001) and TBBMD (β = 0.481, p < 0.01). Height was a significant predictor of LSBMC (β = 0.346, p < 0.001) and TBBMC (β = 0.282, p < 0.001) while fat mass (FM) (β = 0.261, p = 0.034) and physical activity measured as MET scores (β = 0.163, p = 0.026) were significant predictors of TBBMD in boys. Among girls, LM was also a significant predictor of LSBMC (β = 0.620, p < 0.001), LSBMD (β = 0.700, p < 0.001), TBBMC (β = 0.542, p < 0.001) and TBBMD (β = 0.747, p < 0.001). Calcium intake was a significant predictor of LSBMC (β = 0.102, p = 0.034), TBBMC (β = 0.122, p < 0.001) and TBBMD (β = 0.196, p = 0.002) in girls. Conclusions LM was the major determinant of BMC and BMD among pre-adolescent Malaysian children alongside other modifiable lifestyle factors such as physical activity and calcium intake.

Background and objectives: Peritoneal dialysis (PD) patients are expected to present lower levels of physical activity, unhealthy changes at the body composition level, and low levels of strength. Firstly, this study aimed to report the sex differences in physical activity, body composition and muscle strength and the relations among these variables. Secondly, we analyze the relationship between physical activity and biochemical parameters. Materials and Methods: Thirty-four patients (13 women and 21 men) participated in this study. Body composition was assessed by bioimpedance and dual-energy X-ray absorptiometry (DXA), and maximum isokinetic unilateral strength, analytical parameters and physical activity levels were evaluated. Results: The men showed higher values for weight, height, lean body mass, bone mineral content, bone mineral density (BMD) and total body water, while women showed higher values for the percentage of fat mass and hydration of lean body mass (p < 0.05). No differences between the sexes were found in different levels of physical activity; however, males registered significantly higher values for isokinetic strength variables except for knee extensor strength. BMD was positively related to sedentary activity and negatively related to moderate and vigorous activity (r = 0.383 and r = −0.404, respectively). Light physical activity was negatively correlated with albumin (r = −0.393) and total protein (r = −0.410) levels, while moderate/vigorous activity was positively correlated with urea distribution volume (r = 0.446) and creatinine clearance (r = 0.359) and negatively correlated with the triglyceride level (r = −0.455). Conclusions: PD patients with higher levels of physical activity present better results in terms of body composition and biochemical parameters. Additional studies should be conducted to clarify the relation between physical activity level and BMD.

Prevalence Of Osteoporosis

Objective. To study the prevalence of osteoporosis and vitamin D deficiency in healthy men and to explore the influence of various life style factors on bone mineral density (BMD) and also to look at number of subjects warranting treatment.Methods. Ambulatory south Indian men aged above 50 were recruited by cluster random sampling. The physical activity, risk factors in the FRAX tool, BMD, vitamin D, and PTH were assessed. The number of people needing treatment was calculated, which included subjects with osteoporosis and osteopenia with 10-year probability of major osteoporotic fracture >20 percent and hip fracture >3 percent in FRAX India.Results. A total of 252 men with a mean age of 58 years were studied. The prevalence of osteoporosis and osteopenia at any one site was 20% (50/252) and 58%, respectively. Vitamin D deficiency (<20 ng/dL) was seen in 53%. On multiple logistic regression, BMI (OR 0.3;Pvalue = 0.04) and physical activity (OR 0.4;Pvalue < 0.001) had protective effect on BMD. Twenty-five percent warranted treatment.Conclusions. A significantly large proportion of south Indian men had osteoporosis and vitamin D deficiency. Further interventional studies are needed to look at reduction in end points like fractures in these subjects.
