“…Moreover, diet-based weight-reduction programmes for children with obesity have been associated with a reduction in the rate of bone mass accumulation during growth, the latter being proportional to the amount of weight lost. 45 In addition, diet-based weight-reduction programmes are less efficient in eliciting a long-lasting reduction in body weight than programmes combining diet and exercise. 46 It is likely that with nutritional counselling to the families and children a greater effect on fat mass accumulation could have been achieved and additional benefits for health could have also been obtained from sports participation.…”

Objective: To analyse the effect of extracurricular physical activities on fat mass accumulation and physical fitness during growth in early pubertal males. Design: Longitudinal study. Subjects: A total of 42 male children (9.471.4 years, Tanner I-II and 12.771.5 years, Tanner III-IV, before and after the 3.3 years follow-up, respectively), randomly sampled from the population of Gran Canaria (Spain), 26 of them physically active (PA, at least 3 h per week during 3 years) and 16 non-physically active (non-PA). Measurements: Body composition (dual-energy X-ray absorptiometry), anthropometrics (body circumferences and skinfolds) and physical fitness variables (dynamic and isometric force, anaerobic capacity and maximal aerobic power) were determined in all subjects. Results: Both groups had comparable body sizes at the start and the end of the study. Body mass index increased with growth more in the PA than in the non-PA group (Po0.05). However, fat mass accumulation with growth was lower in the PA than in the non-PA (Po0.05). There was a positive relationship between the increment of total and trunkal fat mass, especially in nonactive children (r 2 ¼ 0.93). In contrast, there was an inverse relationship between the total lean mass growth and the accumulation of total and regional fat mass (r ¼ À0.37 to À0.41, all Po0.05). Physical fitness was maintained in the PA, while it worsened in the non-PA children. Conclusions: Without any dietary intervention, children who regularly participate in at least 3 h per week of sports activities are more protected against total and regional fat mass accumulation. They also increase their total lean and bone mass to a greater extent than children who do not participate in extracurricular sport activities. In addition, PA children maintain their physical fitness during growth, while it deteriorates in the non-PA children.

“…(3,4) Weight loss is associated with significant decreases in areal BMD (aBMD) and increased fracture risk in adults (5) and with inadequate bone gain in children. (6) However, little is known about the effects of weight gain in late adolescence on bone geometry or estimated bone strength, because studies to date have exclusively used aBMD (g/cm 2 ) or BMC as outcomes. It is often implied in the literature that a higher aBMD associated with body weight coincides with an increased bone mechanical strength.…”

The effect of weight gain in late adolescence on bone is not clear. Young women who consistently gained weight (n = 23) from 17 to 22 yr of age had increased BMD but a lack of subperiosteal expansion compared with stable weight peers (n = 48). Bone strength increased appropriately for lean mass in both groups but decreased relative to body weight in weight gainers, suggesting increased bone fragility in weight gainers.Introduction: Weight gain leading to obesity often starts in adolescence, yet little is known about its effects on bone. We used longitudinal data to examine the effects of weight gain in late adolescence (from 17 to 22 yr of age) on proximal femur BMD, geometry, and estimates of bending strength. Materials and Methods: Participants were classified as either weight gainers (WG, n ‫ס‬ 23) or stable weight (SW, n ‫ס‬ 48) using a random coefficients model. Weight gainers had positive increases in weight (p < 0.05) at each clinic visit from age 17 onward. Proximal femur DXA scans (Hologic QDR 2000) taken annually from 17 to 22 yr of age were analyzed for areal BMD (g/cm

“…Obese children had higher BMC compared with leaner children, even when adjusted for height, age, gender, and ethnicity (Ellis, et al, 2003). Additionally, weight changes in obese, female adolescents were strongly related to changes in BMC and bone mineral density (Rourke, et al, 2003).…”

“…Obesity during childhood and adolescence was related to increased vertebral bone density (Leonard, Shults, Wilson, Tershakovec, & Zemel, 2004) and increased body BMC (Braillon, Berard, Chatelain, & Pracros, 2002;Leonard, et al, 2004). Additionally, weight changes in obese, female adolescents were strongly related to changes in BMC and bone mineral density (Rourke, Brehm, Cassell, & Sethuraman, 2003). Gender differences in the relationship of BMI and bone mass may be present.…”
