Reproductive health is an vital topic for human beings. In the past years, numerous occupational issues have been observed and recommended to be related to different reproductive outcomes of women. Shift work is one such factor, possibly related to a risk of spontaneous abortion (SA) and reduced fertility. Maximum studies about shift work and SA have been done among nurses, as this occupational group has the highest number of female shift workers in maximum countries. Previous studies among nurses from various countries several years back in time have suggested a relationship between shift work and SA.
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.
