Condom practices of urban teens using Norplant contraceptive implants, oral contraceptives, and condoms for contraception☆,☆☆,★

Study design
We conducted a prospective 2-year cohort study of 399 sexually active adolescent women using either Norplant contraceptive implants, oral contraceptives, or condoms alone. Sample sizes were based on a power calculation performed for continuation rates, the original primary outcome to be evaluated by means of these data and to be reported elsewhere. A 37% difference in continuation rates between implant and oral contraceptive accepters and between implant and condom accepters was expected at 2
Comment
This study’s findings support our first primary hypothesis that teens using Norplant contraceptive implants would use condoms less often than teens using oral contraceptives or condoms alone. Whereas, at admission, the groups did not differ substantially, the discrepancies were significant at both 1 and 2 years of follow-up. Both condom use variables (condom use at last sex and frequency of use) confirmed the general trend of less frequent condom use by implant users than by oral contraceptive
