Extract

The purpose of this paper is two-fold; first, it seeks to examine the differences in menstrual bleeding patterns between users of three IUD models and second, it presents the advantages and disadvantages of the methods of analysis recommended by the Exeter Workshop on Bleeding Pattern Analysis reported by Snowden (1977, see p. 107 of this issue). The principal feature of this means of comparison is that the pattern of menstrual bleeding is assumed to be complex and multivariate. Previous analysis has tended to concentrate on the length of menstrual cycles, where such cycles are denned as the interval between the onset of one period of menstrual bleeding and the next. In addition to this type of information, the present study also incorporates information on the length and variability of periods of bleeding and intervals between bleeding. This information is readily available and easily collected.
