In women, bone loss occurs rapidly in the perimenopausal years. It leads to osteoporosis this eventually progresses to bone damage or fractures without any pain or symptoms. Osteoporosis is a global health threat without prevention and treatment. In this case the bone becomes less dense, resulting in week bones. Calcium is considered to be the primary nutrient required for many of the body functions to run perfectly. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
