^AUse of male condoms either with or without withdrawal, spermicide, and/or outercourse.

^BUse of a hormonal method and male condoms, either with or without withdrawal, spermicide, and/or outercourse.

^CWe used a Spearman correlation coefficient due to the skewed age distribution of the sample.

^*P < 0.05
