Relationship of weight change to required size of vaginal diaphragm.

Abstract

Health care providers are instructed to counsel diaphragm users to return for a re-fitting of the device if there is a change in the patient's weight. Texts on contraception do not give a rationale for this rule. In an effort to explore the effect of weight change on the required size of diaphragm, the charts of 80 diaphragm users were reviewed. All women had at least two visits for diaphragm fitting. A table was constructed with weight and diaphragm size for each subject at each visit. The subjects ranged in age from mid-tens to early forties and all were patients at the same clinic. Chi-square analysis of the data revealed no correlation between weight change and change in diaphragm size.

PIP:

In an effort to explore the effect of weight change on the required size of vaginal diaphragm 80 diaphragm users were studied; all women had at least 2 visits for diaphragm fitting. Of the 50 subjects who had a weight change of 5 or more pounds, 48% kept the same size diaphragm while 52% were fitted with another size. Of the 30 who did not have a weight change of 5 or more pounds, 56.7% also had a change in diaphragms. Of 19 subjects who had a weight change of 10 or more pounds 63.2% had the same size diaphragm and 36.8% were given a different size. It was not shown that a larger proportion of subjects in the experimental groups than in the control groups had a change in diaphragm size. It needs to be seen if placement in the menstrual cycle has an effect on diaphragm size.
