of women age 30 and older reported intending to have UI in the next 3 months ($p < .05$; data not shown). There were no significant differences by race/ethnicity.

\subsection{Reasons for Previous UI}

Women gave an average of 2.7 specific reasons for having UI in the past 3 months. Women who had fewer than three acts of UI gave an average of 1.9 reasons; women who had more UI gave an average of 3.0 reasons ($p < .05$; data not shown). The most common groups of reasons for having had UI in the 3 months before conception were that they did not think they were going to get pregnant (42\%), they had trouble getting a contraceptive method (40\%), and they weren't planning on having sex (38\%) (Table~\ref{tab:table_2}). The most common specific reason was, ``I did not think I was going to have sex'' (34\%), followed by thinking one could not become pregnant because of one's place in the menstrual cycle (20\%), running out of birth control supplies (20\%), and the partner not wanting to use birth control (19\%). What distinguished women who had frequent UI (three or more times in the 3-month period) from women with fewer reported acts was greater reporting of access problems (inability to afford, difficulty getting to the clinic, and not wanting to see a doctor), a history of side effects from contraception, a partner who did not want to use birth control, and a higher level of ambivalence about becoming pregnant.

\subsection{Attitudes Toward UI}

The most prevalent attitude about UI was that it ``feels better or more natural,'' an opinion held by 48\% of respondents. Just over one third (36\%) said it was ``okay to have once in a while or at certain times of the month'' (Table~\ref{tab:table_3}). One in four women (28\%) reported ``relationship and partner reasons'' to have UI. Although this was the least common attitude, partnership and relationship reasons to have UI were significantly associated with a willingness to have UI in the future. Among women who said they were somewhat or extremely likely to have UI in the
