Bone Abstracts

Objectives: i) To assess bone (BMC) by BIA in apparently healthy Indian children. ii) To generate percentile curves for BIA measured BMC by age/gender. iii) To investigate relationship between BMC measured by BIA and DXA in separate subset.Methods: In a multicentre study, 4154 children (2298 boys), 5–18 years underwent BMC assessment by BIA. BMC for age percentiles were computed using LMS method. In 41 children (not from the multicentre study) total...

Objective: Fractures represent a common injury during childhood and adolescence. Knowledge of epidemiology of fractures is crucially important for implementation of prevention strategies for target population. Our objective was to evaluate incidence of fractures in Indian children and adolescents and to investigate association of fractures with physical activity.Methods: Data on history of fracture, age, site of fracture and physical activity were collec...

Objective: Optimal intakes of calcium and milk are necessary in children and adolescents to facilitate not only mineralization but also growth in stature. Low intakes of calcium and also, of milk and milk products in Indian children have been reported. Hence, the objective was to study Indian children’s growth with respect to their calcium and dairy intakes.Methods: We studied 220 children (boys 104, age range 2–16 years). Data on their height,...

Objective: To describe changes in the muscle–bone unit, assessed as the ratio of bone mineral content (BMC) to lean body mass (LBM) at skeletal sites during puberty in Indian males and females, after adjusting for age and fat.Methods: Data on arm, leg and total body (less head) BMC, LBM and fat mass (FM) assessed by DXA for 888 apparently healthy children and adolescents (426 females), 5–17 years of age from a cross-sectional study used to gene...

Objective: Type 1 diabetes mellitus (TIDM) has been shown to adversely affect bone health in children. Hence, objective was to assess bone health status of children with T1DM, and to assess relationship between bone status and disease duration.Methods: Bone mineral content for total body (less head) (TBBMC) and lumbar spine was measured by DXA in 47 (25 boys) children with T1DM. Z-scores for TBBMC for bone area (TBBA), TBBA for height, lean body...

Objective: To study association of VDR gene Fok1 polymorphism locus on bone mass accrual in adolescent girls.Methods: An intervention trial was carried out in 102 girls aged 8–16 years (Pune, India). All girls received 500 mg elemental calcium (daily) and 30 000 IU of vitamin D3 quarterly for 1 year. Outcome variables were measured at baseline and end of the year. Serum levels of ionised calcium (iCa), inorganic phosphorous, parathyroid hor...

Objective: In children, factors such as age and puberty are confounders when investigating associations of fat or lean with bone mineral content (BMC). Our aim was to assess influence of fat on BMC in overweight/obese (ow/ob) and normal weight (nw) children at different stages of puberty.Methods: Cross-sectionally, 244 children+adolescents (6–16 years) (73nw, 177ow/ob) were assessed (tanner staging (TS), body composition (DXA) (total body BMC, lean ...

Objective: Low dietary calcium intakes and increasing adiposity in Indian adolescents may increase their risk of hypertension (Sanwalka et al., Asia Pac J Clin Nutr. 2010, Khadilkar et al., Int J Pediatr Obes. 2010). Therefore, the aim of the present study was to explore association of dietary calcium intakes and body composition with blood pressure in 10–14 year old Indian adolescents.Method: 370 apparently healt...

Objectives: Studies have reported prevalence of vitamin D deficiency in Indian children with adequate sunlight exposure (Harinarayan, 2008). The objectives of our study were to A) examine the prevalence of vitamin D deficiency in children with adequate sunlight exposure in a semi-rural setting in Western Maharashtra (18(°N), India and B) explore the association of serum 7-Dehydrocholesterol reductase (7-DHCR) with the serum vitamin D levels.Methods:...

Objective: The objective of this study was to enable migration of DXA data of patients following replacement of the GE Lunar DPX-Pro, pencil beam densitometer with GE Lunar iDXA, fan beam densitometer.Methods: Scans of total body were conducted for 67 subjects, aged 3.0 to 19.9 years, on both machines. A sub-set of six subjects (3 boys) were randomly selected and reserved as a validation sample. Differences between the values obtained on the two machines...
