We conducted a cluster-randomized community intervention trial at Kenyan ag
ricultural sites to measure the impact of female condom introduction on sex
ually transmitted infection (STI) prevalence. We present male and female co
ndom use data here. Six Intervention sites received a community risk-reduct
ion campaign and distribution of female condoms and male condoms, while 6 C
ontrol sites received the same campaign with male condoms only. Male and fe
male condom distribution increased throughout follow-up. Self-reported male
condom use increased substantially during follow-up to over 60% of the par
ticipants. The proportion of consistent male condom users at Control sites
was higher than at Intervention sites, 23% vs 14% at 6 months and 24% vs 22
% at 12 months. At Intervention sites, 11% and 7% of women used the female
condoms all the time at 6 and 12 months, respectively, while the percentage
of female condom non-users grew. Male and female condom use was hindered b
y male partner objections; suspicion of the study and the devices among res
idents; and bias against condoms by clinic service providers. A large propo
rtion of coital acts remained unprotected during the trial. Our female cond
om intervention did not reduce STI prevalence, compared with male condom pr
omotion only.
