Association between depression and contraceptive patterns over the year after initiating among young women who initiated prescription contraception in 2014–2016 at Kaiser Permanente Northern California (aRRRs and 95% CIs)

	Discontinued	Gaps in use and no switching	Switched methods and no gaps	Switched methods and gaps
All contraceptive initiators (n = 52,325)

Notes. The adjusted relative risk ratios (aRRR) presented compare women with depression indicators to women with no depression indicators (reference group). Comparison group of the multinomial logistic regression is those who used their initiated method continuously and consistently for the entire year. Those who discontinued their method did not start another method for the entire year. Models adjusted for race/ethnicity, age, income, recent abortion, and recent birth. The first analysis among all contraceptive initiators also controlled for method type initiated. No interactions between recent birth or abortion and depression were significant.
