In a nationally representative sample of men aged 17-22, 23% of those using condoms reported experiencing at least one condom break during the previous 12 months. Of all condoms used, 2.5% had broken. In multivariate analyses, increased experience with condoms reduced the likelihood of experiencing condom breakage. Recent sex education was associated with an almost 80% decrease in the risk of breakage among young men who used condoms infrequently. Young males who had ever had a sexually transmitted disease (STD), or whose sexual-partner had had an STD, were almost three times as likely as other respondents to have experienced condom breakage. In addition, young men with a household income of less than $60,000 were 2-3 times as likely to have broken a condom as were those with a higher household income.
