The aim of the study was to evaluate the relationship between sedentary behavior, bone mass, and bone geometry among young male basketball and volleyball players. This cross-sectional study included 55 adolescent basketball ( n = 21) and volleyball ( n = 34) players (14–17 years). Body composition (body mass index, fat mass, and lean mass) was measured by dual-energy X-ray absorptiometry, comprising bone mineral density, bone mineral content at the lumbar spine, and femoral neck. Bone geometry considered the femur strength index, section modulus, cross-sectional moment of inertia, and cross-sectional area. Dietary intake was obtained through a semiquantitative questionnaire, and the sedentary behavior, by the Adolescent Sedentary Activity Questionnaire. Linear regression models, fitted by Bayesian methods, explored the variation of the variables by sport. Body composition and bone mass values were high for both sports, but there was no variation for body composition. Adjusting for age, there was no association of sedentary behavior on bone parameters. For femoral strength index, age had a moderate to large association with all bone indicators. Lastly, there was influence of sport (level-2 unit) on the estimates of the association between sedentary behavior and age with bone indicators, as uncertainty estimates for group-level effects were high. There is no association between sedentary behavior and bone parameters, showing that accumulated training loads (15+ h/wk) among young basketball and volleyball players are critical; producing a positive stimulus on bone parameters development.

Abstract Background: Sedentary behavior is considered a health risk independent of physical activity. We evaluated the relationship between sedentary behavior, bone mass, and bone geometry among young male basketball and volleyball players.Methods: Fifty-five athletes (basketball n=21; volleyball n=34) aged 14 to 17 years old were included. Body composition and bone mass were measured by dual-energy X-ray absorptiometry, comprising bone mineral density, bone mineral content at the lumbar spine (L1-L4), and femoral neck. Bone quality was evaluated by bone geometry considering the femur strength index, section modulus, cross-sectional moment of inertia, and cross-sectional area. Information on all foods and beverages were obtained by a nutritionist through a 24-hour food recall and a semi-quantitative food frequency questionnaire. The sedentary behavior was assessed using the Adolescent Sedentary Activity Questionnaire. A series of multilevel linear regression models were fitted to explore whether there was variation for players' body composition, bone parameters, diary nutrient intake and sedentary behavior by sport. All models were fitted using Bayesian methods.Results: Body composition and bone mass values were high for both basketball and volleyball players. However, there was no substantial variation between players by sport for body composition. Adjusting for age, there was no association of sedentary behavior on both bone mass and geometry among the athletes. Except for femoral strength index, age had a substantial moderate to large association with all bone mass and geometry indicators. Lastly, there was no substantial influence of sport (level-2 unit) on the estimates of the association between sedentary behavior and age with bone mass and geometry, as uncertainty estimates for group-level effects were high. Conclusions: In conclusion, there is no association between sedentary behaviour and bone mass and bone geometry, showing that accumulated training loads (15+ h/week) among young basketball and volleyball players are critical; they produce a positive stimulus on bone mass and bone geometry development.

Objectives: Transgender individuals submitted to hormone or surgical treatment may have alterations in their bone metabolism as these elements are important players in bone remodeling. We aimed to study bone mineral density (BMD) and body composition in transwomen undergoing cross-sex hormonal treatment (CSHT) from Brazil for over 3 years, comparing them with female and male controls. Methods: 93 individuals (31 transwomen, 31 females and 31 males paired for age and body mass index) were studied for bone mass, and body composition by densitometry (by DXA). Epidemiological and clinical data were collected through direct questioning. Results: Low bone mass (T score ≤2) was found in 12.9% of transwomen; in 3.2% of females and 3.3% of males. Transwomen individuals had lower spine Z score (0.26 ± 1.42 vs 0.50 ± 1.19) and femur Z score (−0.41 ± 0.95 vs 0.29 ± 1.04) than females. They had lower total femur Z score than males (−0.41 ± 0.95 vs 0.20 ± 0.83). Lean mass values correlated positively with total femur BMD (ρ = 0.40; 95% confidence interval = 0.009–0.68; p = 0.04) and BMD in femoral neck (ρ = 0.48; 95% confidence interval = 0.11–0.74; p = 0.01) but neither the type of therapy received nor the time that they were used, impacted bone mass. Conclusion: Low BMD is found frequently in transwomen and it is correlated with lean body mass. Advances in knowledge: There are few studies of the effects of hormone therapy on the bones and muscles of transwomen. This study demonstrated that significant changes occur, and that the population studied needs greater care in musculoskeletal health.

Wang Q, Ravn P, Wang S, Overgaard K, Hassager C, Christiansen C. Bone mineral density in immigrants from southern China to Denmark: a cross-sectional study. Eur J Endocrinol 1996;134:163–7. ISSN 0804–4643 Immigration from Japan to USA has been shown to increase bone mineral density (BMD) and body fat in women. The effects of immigration between other geographical areas on bone mass and body composition are largely unknown, especially in men. In the present study, we measured bone mass and body composition by dual energy X-ray absorptiometry (Hologic QDR-2000) in 73 healthy premenopausal women (age 35 ± 8 years) and 69 men (age 40 ± 12 years) who had immigrated from southern China to Denmark 2 months to 36 years ago. The BMD measurements (Total BMD, trunk BMD and leg BMD) were related positively to years since immigration (YSI) (R2 = 0.10–0.16, p < 0.05) in premenopausal women, but not in men. Fat distribution was related mainly to age in both premenopausal women and men (R2 = 0.16–0.26, p < 0.05). For comparison, we included 51 white, Danish premenopausal women (age 36 ± 6 years). Chinese premenopausal women with a YSI below or equal to 12 years (N = 38) had significantly lower total and regional BMD (trunk, legs, arms) (p < 0.05), while women with a YSI above 12 years (N = 35) had significantly lower BMD in the legs only (p < 0.05) when compared to the Danish premenopausal women. After correction for age, weight and height, Chinese premenopausal women with a YSI below or equal to 12 years still had significantly lower BMD in all regions (4–7%, p < 0.05), whereas no differences in BMD were found between Chinese premenopausal women with a YSI above 12 years compared with Danish premenopausal women. In conclusion, Chinese premenopausal women who immigrated to Denmark more than 12 years ago have a similar BMD to that of Danish premenopausal women. In the group who immigrated less than 12 years ago, a significantly lower BMD was found. P Ravn, Center for Clinical and Basic Research, Ballerup Byvej 222, DK-2750 Ballerup, Denmark

Objective.To assess the prevalence of reduced spine bone mineral apparent density (BMAD), and to identify the main predictors of reduced spine BMAD in a cross-sectional and longitudinal evaluation of the same large cohort of patients with juvenile idiopathic arthritis (JIA). There are few prospective data on bone mass evaluation in a large number of patients with JIA, and with enthesitis-related arthritis onset.Methods.Two hundred nineteen patients with JIA (median age 8.7 yrs, range 6.1–13.1 yrs; 104 oligoarticular JIA, 61 polyarticular, 20 systemic, and 34 enthesitis-related arthritis onset) were retrospectively evaluated. A dual-energy x-ray absorptiometry (DEXA) scan at the lumbar spine was performed in all subjects. Of these, 89 consecutive patients were followed up randomly and longitudinally with a second and a third DEXA evaluation. The data obtained were compared with 80 age-matched and sex-matched healthy subjects.Results.At the first DEXA, patients with JIA showed a reduced spine BMAD standard deviation score (SDS) in comparison to controls (p < 0.001). These results were confirmed when the subjects were divided into JIA subtypes (p < 0.005) with the exception of enthesitis-related arthritis onset. Spine BMAD SDS significantly correlated with JIA onset type (p < 0.01), age at JIA onset (p < 0.005), and flares (p = 0.008). The longitudinal evaluation showed that spine BMAD SDS did not significantly improve at the followup in comparison to controls, in all subsets with JIA except for systemic onset (p < 0.05). Spine BMAD correlated with sex (p < 0.01), systemic corticosteroid exposure (p < 0.01), the number of intraarticular corticosteroid injections (p < 0.01), the interval from last steroid injection (p < 0.05), erythrocyte sedimentation rate (p < 0.005), and C-reactive protein levels (p < 0.005).Conclusion.Patients with JIA have a low bone mass and, after a first increase due to therapy, do not reach a healthy condition over time despite our current more effective drugs. These patients have a high risk of osteoporosis in early adulthood. To reduce the risk and improve the bone mass, close monitoring of bone mineral density, better control of disease activity, physical activity, and intake of calcium and vitamin D are recommended. In patients with osteoporosis, therapeutic approaches including bisphosphonates should be considered.

Idiopathic Osteoporosis

ObjectiveSclerostin inhibits osteoblast differentiation and bone formation. If aberrant sclerostin action is involved in less efficient bone acquisition in men with idiopathic low bone mass, this might be reflected in higher serum sclerostin levels.MethodsIn 116 men with idiopathic osteoporosis (≤65 years old), 40 of their sons and healthy controls, areal bone parameters were measured using dual-energy X-ray absorptiometry, and volumetric and geometric bone parameters were measured using peripheral quantitative computed tomography. Serum analytes were measured using immunoassays and estradiol (E2) levels using liquid chromatography–tandem mass spectrometry.ResultsMen with idiopathic low bone mass had lower levels of sclerostin than the controls (0.54±0.17 vs 0.66±0.23 ng/ml;P<0.001). In both groups, sclerostin levels were strongly associated with age; when adjusting for age, no associations with anthropometrics were observed (P>0.14). In multivariate analyses, sclerostin levels displayed a positive association with whole-body bone mineral content (BMC) and areal BMD (aBMD), as well as with trabecular and cortical volumetric bone mineral density (vBMD) at the tibia in the probands. No clear associations were observed in the control group, neither were sclerostin levels associated with BMC at the radius or lumbar spine (allP>0.11). Testosterone, but not E2, was inversely related to sclerostin levels in the probands. No difference in sclerostin levels was found in their sons when compared with their controls.ConclusionLower rather than higher serum sclerostin levels in the probands with idiopathic low bone mass suggest that aberrant sclerostin secretion is not involved in the pathogenesis of low bone mass in these subjects.

Pendahuluan. Tingginya angka kejadian HIV/AIDS pada usia muda yang mencapai 50% dari total kasus HIV/AIDS di Indonesia menjadi permasalahan yang serius, khususnya terkait kualitas hidup pasien. Selain infeksi oportunistik, keadaan osteopenia dan juga osteoporosis sering ditemukan pada pasien dengan HIV/AIDS. Namun demikian, penelitian mengenai gambaran massa tulang pada pasien HIV/AIDS di Indonesia sampai saat ini belum didapatkan.Metode. Studi potong lintang dilakukan pada pasien dewasa dengan infeksi HIV naif antiretroviral di Rumah Sakit dr. Cipto Mangunkusumo (RSCM) Jakarta pada Februari-Mei 2008. Pemeriksaan bone mineral density (BMD) dilakukan dengan menggunakan DXA scanning. Hasil. Berdasarkan pemeriksaan BMD didapatkan sebanyak 29,3% subjek ostopenia, 1,3% osteoporosis dan sisanya normal. Osteopenia/osteoporosis didapatkan lebih besar pada subjek yang mengonsumsi alkohol, merokok, hitung limfosit CD4+ <200 sel/mm3 dan IMT<18,5 dengan proporsi masing-masing secara berturut-turut yaitu 53,6%; 36,9%; 35,5%; dan 37,6%. Lama infeksi HIV pada penelitian ini tidak menunjukkan hasil yang berbeda.Simpulan. Didapatkan keadaan osteopenia dan osteoporosis pada pasien dengan HIV/AIDS. Pada pasien HIV/AIDS dengan riwayat merokok, konsumsi alkohol, hitung limfosit CD4+ <200 sel/mm3 dam IMT rendah, didapatkan angka osteopenia/osteoporosis yang lebih tinggi.Kata kunci: HIV, naif antiretroviral, osteopenia/osteoporosis Bone Mass Density in HIV/AIDS PatientsIntroduction. Indonesia has a high incidence of young HIV-positive population which is 20-29 years of age is in the highest group (50%). For this reason, it is important to make a better quality of life for them. Unfortunately, beside all the opportunistic infection, it was proved that osteopenia/osteoporosis has become a new emerging metabolic condition for HIV-infected patients. There is still no study about the description of bone mass density in HIV/AIDS patients in Indonesia. Methods. A cross sectional study was conducted in a total of 75 HIV-seropositive antiretroviral-naïve patients. Bone mineral density (BMD) was determined by dual energy X-ray absorptiometry in lumbar spine. Results. Seventy-five subjects had been recruited. Low BMD was found in 29.3% HIV-seropositive patients with osteopenia and 1,3% with osteoporosis. There was a higher number of osteopenia/osteoporosis in subjects who consume alcohol, smoking, lymphocyte CD4 <200 cells/mm3 and low body mass index (BMI). Duration of infection did not show any differences in both HIV with osteopenia/osteoporosis and subjects with normal bone condition. Conclusions. Osteopenia and osteoporosis were found in patients with HIV/AIDS in RSCM with lower bone density in subjects who consumed alcohol, smoke, lymphocyte CD4 <200 cells/mm3 and low BMI.

ABSTRACT Objective To evaluate bone mineral mass in adolescents with failure to thrive in relation to body composition. Methods A case control study involving 126 adolescents (15 to 19 years), in final puberty maturation being 76 eutrophic and 50 with failure to thrive (genetic or constitutional delay of growth), of matching ages, gender and pubertal maturation. The weight, height and calculated Z score for height/age and body mass index; bone mineral content, bone mineral density and adjusted bone mineral density were established for total body, lower back and femur; total fat-free mass and height-adjusted fat-free mass index, total fat mass and height-adjusted. The statistical analyses were performed using the Student's t-test (weight, height and body composition); Mann-Whitney test (bone mass) and multiple linear regression (bone mass determinants). Results weight, height and height/age Z-score were significantly higher among eutrophic subjects. Both groups did not show statistically significant differences for fat mass, percentage of fat mass, total fat mass height adjusted and fat-free mass index height sadjusted. However, total free fat maass was smaller for the failure to thrive group. Conclusions There was no statistically significant difference for bone mass measurements among adolescents with failure to thrive; however, the factors that determine bone mass formation should be better studied due to the positive correlation with free fat mass detected in these individuals.
