Role of young women's depression and stress symptoms in their weekly use and nonuse of contraceptive methods

Purpose: We prospectively examined the influence of young women's depression and psychological stress symptoms on their weekly contraceptive method use. Methods: We examined data from 689 women ages 18-20 years participating in a longitudinal cohort study. Women completed 8,877 weekly journals over the first year, which assessed reproductive, relationship, and health information. We focused on baseline depression (Center for Epidemiologic Studies-Depression Scale) and stress (Perceived Stress Scale) symptoms and weekly contraceptive method use. Analyses used multivariate random effects and multinomial logistic regression. Results: Approximately one quarter of women exhibited moderate/severe depression (27%) and stress (25%) symptoms at baseline. Contraception was not used in 10% of weekly journals, whereas coital and noncoital methods were used in 42% and 48% of weeks, respectively. In adjusted models, women with moderate/severe stress symptoms had more than twice the odds of contraception nonuse than women without stress (odds ratio [OR] 2.23, confidence interval [CI] 1.02-4.89, p =.04). Additionally, women with moderate/severe depression (RR.52, CI.40-.68, p <.001) and stress (relative risk [RR].75, CI.58-.96, p =.02) symptoms had lower relative risks of using long-acting methods than oral contraceptives (OCs; reference category). Women with stress symptoms also had higher relative risks of using condoms (RR 1.17, CI 1.00-1.34, p =.02) and withdrawal (RR 1.29, CI 1.10-1.51, p =.001) than OCs. The relative risk of dual versus single method use was also lower for women with stress symptoms. Conclusion: Women's psychological symptoms predicted their weekly contraceptive nonuse and use of less effective methods. Further research can determine the influence of dynamic psychological symptoms on contraceptive choices and failures over time.
