Studies have confirmed that resistance training can have a beneficial effect on bone mineral contents. But, it is not well established that which type of sporting activity is more beneficial for increased bone mineral density (BMD). The objective of the study was to find out the difference in the BMD between various sporting activities. As a part of study, bone mineral density of elite sportsmen belonging to various type of sports in respect to weight bearing, resistance and impact were compared. Research design for present study was a cross-sectional design. A total of 120 elite sportsmen (mean age=22.14 years, mean BMI=24.89 kg/m2), who have won first/second/third position at least at national/ inter-university levels in the discipline of Weight lifting (N - 22), Volleyball (N – 24), Basketball (N – 24), Athletics (Long distance, Middle distance and Cross-Country runners) (N – 25) and Cycling (N – 24) participated in the study. Bone mineral density was measured by using Ostepro-ultrasound bone mineral density system. The ANOVA results revealed statistically significant difference between different groups for right and left leg Calcaneal Bone Mineral Density (g/cm2) with F value of 9.14 (p<0.01) and 8.38 (p<0.01) respectively, indicating that there exists a significant difference in the BMD between various groups. Further, when BMD was compared between sportsmen of various categories with weightlifters for right leg Calcaneal Bone Mineral Density, the t value was significant (Volleyball, Basketball, Athletics and Cycling the t-value was 18.20, 20.29,14.06 and 21.76 respectively). Similarly, t value was significant (Volleyball – 15.92, Basketball – 20.44, Athletics – 10.09 and Cycling – 21.64) when left leg Calcaneal Bone Mineral of weight lifters were compared with other categories. It is concluded that bone mineral density is higher in sportsmen who participate in higher static resistance weight-bearing in comparison to high-impact weight-bearing and no-impact no weight-bearing.

Vestibular Influence

To determine whether the vestibular system could influence bone remodeling in rats, we measured bone mineral density with dual energy X-rays absorptiometry before and 30 days after bilateral labyrinthectomy. Comparatively to intact control rats, labyrinthectomized animals showed a reduced bone mineral density in distal femoral metaphysis (p = 0.007): the variations between D0 and D30 were +3.0% for controls and -13.9% for labyrinthectomized rats. No significant difference between the 2 groups was observed in the whole body mineral density. These results suggest that the peripheral vestibular apparatus is a modulator of bone mass and more specifically in weight bearing bone. We discuss possible mechanisms of this vestibular influence probably mediated by the sympathetic nervous system.

This research aimed to investigate the relationship between abdominal obesity and lower bone mineral density (BMD) at non-weight-bearing site in Korean men using data from the Korea National Health and Nutrition Examination Survey, which is a nationwide cross-sectional survey. The study population ( n = 5,941) was selected from the 2009–2010 survey. Abdominal obesity in men was defined as waist circumference ⩾ 90 cm. Lower BMD state was defined as having T-score of −2.5 or below. To investigate the association, multiple logistic regression analysis was performed. Abdominal obesity was highly associated with lower non-weight-bearing site (lumbar spine [LS]) BMD after adjustment (odds ratio [OR] 1.61, 95% CI [1.06, 2.44], p = .026). Also, abdominal obesity was a risk factor for lower LS BMD, especially in age groups of those in their 20s and those over 60s (OR 5.53, 95% CI [1.27, 24.07], p = .023 for 20s; OR 2.19, 95% CI [1.19, 4.02], p = .011 for 60 years or older). Abdominal obesity in Korean men is associated with lower BMD at non-weight-bearing site (LS), especially in younger and older age groups. Further research might be recommended to prove the mechanism or causality.

Background. Besides lipid-lowering effect of statins, they have been shown to have nonlipid lowering effects, such as improving bone health. An improvement in bone mineral density (BMD) has been indicated in some studies after the use of statins, in addition to an increase in 25-hydroxyvitamin D (25OHD) level. The aim of this study is to explore the association between statins and bone health taking into consideration 25OHD level and BMD.Methods. This is a randomized, cross-sectional comparative study. Subjects were divided into two groups, hypercholesterolemic participants taking simvastatin or atorvastatin as the study group and a matched control group not taking statins. All participants were assessed for serum 25OHD and BMD at lumbar spine and femoral neck.Results. A total of 114 participants were included in the study, 57 participants in each group. Results of serum 25OHD showed no significant difference between study and control groups (P=0.47), while BMD results of lumbar spine and femoral neck showed significant difference (P=0.05and 0.03, resp.).Conclusion. Simvastatin and atorvastatin, at any dose for duration of more than one year, have no additive effect on 25OHD level but have a positive effect on the BMD.

Background: Diabetes Mellitus is one of the most common chronic non-communicable diseases in the world. The relationship between type 2 diabetes mellitus (T2DM) and bone mineral density (BMD) has been controversial. Early identification of reduction in bone mass in a diabetic patient may be helpful in preventing the bone loss and future fracture risks. Objective: The aim is to study the effect of T2DM on BMD among patients in western Odisha.Methods: A cross-sectional study was conducted on 120 patients between 40 and 65 years of age which included 60 diabetic and 60 nondiabetic subjects. BMD was measured using qualitative ultrasound and the data were compared among age-matched subjects of both the groups. Statistical analysis was performed using unpaired Student's t-test and test of equality of proportions.Results: No significant difference was observed in bone density of both the groups. On further analyzing the data, incidence of osteoporosis was higher among diabetic subjects, whereas incidence of osteopenia was higher among nondiabetic subjects.Conclusions: Although significant difference in bone mineral density was not observed in both the groups, the incidence of osteoporosis was higher among type 2 diabetics. Hence, all type 2 diabetics should be evaluated for the risk of osteoporosis and should be offered appropriate preventive measures.

SummaryThe present cross-sectional research was designed to study possible correlations between clinical reproductive factors and bone mineral density (BMD) values.Using the data gathered by the population-based Iranian Multicenter Osteoporosis Study (IMOS), we investigated the correlation found between reproductive factors and osteoporosis. Subjects were recruited from five major cities of Iran. Bone mineral density was measured using Dual-Energy X-ray Absorptiometry and the results were analyzed against the age at menarche and at menopause, number of pregnancies, children and abortions, and the history (and duration) of breastfeeding.Data was available for 2528 women. Gravidity and number of children were reversely correlated with BMD. Younger age at menarche was associated with higher BMD values, whereas there was no significant correlation between age at menopause and menstrual history and BMD.Our study suggests that clinical reproductive factors, particularly number of children and breastfeeding, could be incorporated as predictors of BMD levels in women. Given the controversial results obtained in different studies, longitudinal studies should be carried out to enlighten the importance of these factors and the rationale of their use to predict BMD values in different settings.
