INTRODUCTION: Given changes in @entity146 and norms in the United States, there is a need for current and representative data on @entity146 with particular interest in gender, age, and racial/ethnic group differences. AIM: Given the limited data for Hispanics and for Puerto Rico (PR), we described patterns of @entity146 and characteristics among a sexually active sample (n=1,575) of adults aged 21-64 years in PR. MAIN OUTCOME MEASURES: The main outcome measures for this study are @entity146 including age at sexual initiation, number of sexual partners, vaginal and anal intercourse, and oral sex, among others. METHODS: Data from a population-based cross-sectional study in PR (2005-2008) was analyzed. The prevalence of @entity146 and characteristics was described by age-group and gender during the lifetime and in the past 12 months. RESULTS: Overall, 96.8%, 81.6%, and 60.9% of @entity1 had ever engaged in vaginal, oral and anal sex, respectively, whereas 23.7% were seropositive to any of the sexually transmitted infections under study. Sexual initiation <=15 years was reported by 37.8% of @entity1 and 21.4% of @entity1 ; whereas 47.9% of @entity1 and 13.2% of @entity1 reported to have had >= 7 sexual partners in their lifetime. Approximately, 3% of @entity1 and 6% of @entity1 reported same-sex sexual practices, while history of forced sexual relations was reported by 9.6% of @entity1 and 2.5% of @entity1 . Sexual initiation <=15 years was more common among individuals aged 21-34 years (41.4% @entity1 and 33.6% @entity1 ) as compared with older cohorts. Although having had >= 7 sexual partners over a lifetime among @entity1 was similar across age groups, this behavior decreased in older @entity1 cohorts. In both genders, the prevalence of oral and anal sex was also lower in the older age cohorts. CONCLUSION: This study provides essential information that can help health professionals understand the sexual practices and needs of the population of PR.
