Relationship of weight change to required size of vaginal diaphragm.
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.
