The study aimed to explore the effect of moderate daily physical activity on total and segmentalbone mineral content and density (BMC & BMD) of active female employees. It was conducted as cross-sectional study on 142 femalevolunteers from employees of Mosul and Ninevah universities. Their mean age was (53.45±7.6) years and BMI (33.07±5.69) Kg/m2. Based on Allied Dunbar Fitness survey classification, 44(31%) of female employees were considered active, while 98 (69%) female employees were considered inactive. No age or BMI differences were found in between both groups. Dual-energy X-ray absorptiometry (DXA) results revealed that total BMC of active group (1.94) kg was significantly higher than total BMC of inactive group (1.59) kg (p=0.001). Segmental BMC of dependent parts of body (lumber vertebrae, pelvis & lower extremities) were significantly higher in active group in comparison to inactive group (p=0.01, 0.05, & 0.02) respectively. Total BMD of active group (0.96) g/cm2 was significantly higher than total BMC of inactive group (0.83) g/cm2(p=0.04). Segmental BMD of all parts of body (upper extremities, trunk, & lower extremities) were significantly higher in active group in comparison to inactive group.In conclusionpracticing moderate physical activity will raise bone mineral content and density especially in dependent part of body which exposed to highest level of strenuous forces.
