Nutritional Sciences Method class(the effects of physical activity and calcium intake on bone mineral density (BMD) in Saudi women based on DXA measurements) - Research Proposal Example 200, 30-50 years old Saudi women will be recruited within Jeddah or Riyadh and screened to exclude lactating, pregnant mothers and mothers with kidney, skeletal, menstrual dysfunction and any related disorders. Validated food frequency questionnaire specific to calcium will be used to assess consumption of dairy products at baseline and at 9 months. Subjects will record their exercise activities, both weight bearing and none weight bearing that they would have engaged in on a regular basis for at least 2 months. BMD will be assessed by Dual energy x-ray absorptiometry (DXA). Data will be analysed by Statistical Package for Social Sciences version 6 (SPSS, v.6). A 3-way ANOVA, group-time-calcium intake will be used to determine possible effects of interaction in BMD between training mode and dietary calcium from baseline to 9months while statistical significance will be set at p Low Bone Mass Density is a skeletal disorder that is characterized by reduced strength of an individual bone’s density thus results into reduced strength predisposing an individual to an increased risk of fracture. Reduced bone mass density can be less severe and extreme severe depending on the stage of the disorder and can be classified as osteopaenia which is less severe or osteoporosis which is more severe. Osteoporosis and osteopaenia which are characterized by reduced BMD are an indication of decrease, structural deterioration as well as loss of connectivity within the bone tissue resulting into increased
