Relationship between weight change and diaphragm size change.
To evaluate the necessity of refitting the vaginal contraceptive diaphragm after weight loss or gain, an ex post facto/correlational study examined the relationship between body weight change and diaphragm size change. The hypothesis that no relationship exists between weight change and diaphragm size change was tested by selecting 125 clients from two family planning agencies. Weight change and diaphragm size change were compared statistically via chi-square tests, two-tailed t-tests, and regression analysis, revealing overwhelming support of the hypothesis. No significant relationship between weight change and diaphragm size change was found, which suggests that refitting the vaginal diaphragm after weight loss or gain is unnecessary.
