Validity of perceived weight gain in women using long-acting reversible contraception and depot medroxyprogesterone acetate - 21/12/12
Résumé |
Objective |
The objective of the study was to evaluate perceived weight gain in women using contraception and determine the validity of self-reported weight gain.
Study Design |
We analyzed data from new contraceptive method users who self-reported a weight change at 3, 6, and 12 months after enrollment. We examined a subgroup of participants with objective weight measurements at baseline and 12 months to test the validity of self-reported weight gain.
Results |
Thirty-four percent of participants (1407 of 4133) perceived weight gain. Compared with copper intrauterine device users, implant users (relative risk, 1.29; 95% confidence interval, 1.10–1.51) and depot medroxyprogesterone acetate users (relative risk, 1.37; 95% confidence interval, 1.14–1.64) were more likely to report perceived weight gain. Women who perceived weight gain experienced a mean weight gain of 10.3 pounds. The sensitivity and specificity of perceived weight gain were 74.6% and 84.4%, respectively.
Conclusion |
In most women, perceived weight gain represents true weight gain. Implant and depot medroxyprogesterone acetate users are more likely to perceive weight gain among contraception users.
