Osteoporosis is a major public health concern in Canada and worldwide. Although much is known about bone health in older adults, little is known about bone health in young, healthy Canadian men and women. The objectives of this research were to describe bone mineral density (BMD) of young, healthy adults living in southern Ontario, Canada, and to identify predictors of BMD in this population. Two-hundred and fifty-eight Caucasian men and women aged 18–33 years completed health and physical activity questionnaires along with a calcium and vitamin D specific food frequency questionnaire. Height and mass were measured. BMD of the total hip, femoral neck, spine, and total body was measured using dual energy X-ray absorptiometry. Among men, body mass, weight-bearing physical activity, and calcium intake were significant predictors of BMD. Among women, body mass, calcium intake, and family history of osteoporosis significantly predicted log BMD. The predictors of BMD in young Canadian men and women identified in this study may inform the development of longitudinal studies designed to examine the influence of lifestyle factors on BMD in young adults.

BACKGROUND Menopause is defined as the permanent cessation of menstruation following loss of ovarian activity. One of the most important problems associated with menopause is osteoporosis. This study was conducted to evaluate the relationship between bone mineral density, body mass index, age, serum calcium, and serum magnesium in 120 women. METHODS Present study was an observational study done from Feb 2017 to July 2017 in Pt. J.N.M. Medical College to evaluate the relationship of bone mineral density with age, body mass index (BMI), obesity and serum magnesium in 120 postmenopausal women. A detailed medical, obstetrical, menstrual, and drug history was recorded in a proforma designed for the study. Past fracture history, family history of fracture and osteoporosis, socioeconomic status, occupation, educational level and weightbearing exercises were collected and recorded. RESULTS Average age of women with normal bone health was 30.5 + 0.58 years, while the age of osteopenic and osteoporotic women was 43.11 + 6.79 years and 54.64 + 11.92 years respectively. Most of the osteopenic women belonged to the age group of 40 – 49 years. Osteoporotic patients (78.57 %) had a high (> 0.85) waist-hip ratio, while women with normal bone mineral density had a normal waist-hip ratio. Most of the women with normal bone mineral density (100 %), osteopenia (85.29 %) and osteoporosis (57.14 %) had normal serum magnesium levels. CONCLUSIONS We found that the bone mineral density reduced with advancing age, decreasing BMI and obesity, while we found no correlation of serum magnesium level with bone mineral density (BMD). KEY WORDS Bone Mineral Density, Body Mass Index, Perimenopause, Magnesium, Calcium

<strong>Background:</strong>Osteoporosis and Obesity are severe public health problems. Body weight and Body Mass Index (BMI) are considered strong predictors of osteoporotic fractures.<p><strong>Objectives:</strong> The interest of several studies has been focused on women, but there are only few studies worldwide focused on this issue in men. The objective is to focus towards evaluation of Bone Mineral Density (BMD) in male population.</p><p><strong>Material and Methods:</strong> The study was conducted on 400 men up to the age of 80 years. Subjects having history of diseases or drugs that might influence BMD were excluded from the study. Height (m) and weight (kg) were measured and BMI was calculated. Calcaneus bone was scanned for QUS to measure BMD. The diagnosis of Osteoporosis and Osteopenia were done according to WHO T- score criteria. The whole data was collected and statistically analyzed using Correlation Coefficients and Pearson's Chi Square test.</p><p><strong>Results:</strong> Pearson's correlation analysis showed a negative correlation between age and BMD and between age and BMI, and a positive correlation between BMI and BMD. Pearson's chi square analysis showed that BMI had a highly significant association with BMD whereas age had a highly significant association with BMD.</p><p><strong>Conclusions:</strong> Although the results show significant relationship between BMI and BMD, the negative relationship of age with BMI and BMD may serve as a guidance to initiate early assessment of BMD as preventive measure of osteoporosis and fractures among ageing men population.No abstract</p>

In this prospective, cross-sectional study male adolescent tennis players (44) and nonathletic controls (32) were evaluated to determine the effects of physical activity, dietary nutrient intakes, sexual maturation, and body composition on bone-mineral density (BMD). Dietary nutrient intakes and physical activity expenditure were estimated by 4-d diaries. Total body composition, bone-mineral content (BMC), and BMD (L1–L4, femur, and nondominant forearm) were assessed by dual-energy X-ray absorptiometry. Tennis players had significantly greater lean body mass (mean [SEM] 50.6 [1.6] kg vs. 45.1 [1.7] kg, p = .022), trochanter BMD (1.0 [0.02] g/cm2 vs. 0.9 [0.03] g/cm2, p = .032), and dominant forearm BMC (173.7 [7.4] g vs. 146.5 [9.3] g) but lower BMD in the nondominant forearm (0.7 [0.02] g/cm2 vs. 0.8 [0.03] g/cm2, p = .028). Daily average calcium intake was below the recommendation in both groups. No correlation was found between BMD and calcium intake and exercise. Lean body mass was the best predictor of BMD and BMC for both tennis players and controls (R2 = .825, .628, and .693 for L1–L4, total femur, and nondominant forearm, respectively). Based on these results the authors conclude that lean body mass is the best predictor of BMD and BMC for both tennis players and others. Tennis exerts a site-specific effect, and training should focus on ways minimize this effect. Although calcium intake showed no effect on BMD, nutrition education for young athletes should focus on promoting a balanced diet, providing energy and nutrients in adequate amounts.
