A cross-sectional study was carried out among 1284 male and 54 female
prisoners to assess the prevalence of and risk factors for sexually tr
ansmitted diseases (STD) in 4 correctional institutions of Maputo, Moz
ambique. Among the men, 32% reported a history of prostitute contact a
nd 41% reported a history of STD. Only 9% reported having ever used co
ndoms. Seventy (5.5%) men reported having had sexual intercourse while
in prison, in all but one instance this involved sex with another man
. There was no reported intravenous drug use. One hundred and four (7.
8%) inmates had positive serological tests for syphilis and 8 (0.6%) h
ad antibodies to HIV. Among men, syphilis was associated with a histor
y of genital ulcer [odds ratio (OR)=3.1, 95% confidence interval (CI)=
1.4, 6.4] and uncircumcised status (OR=1.5, 95% CI=1.0, 2.5). This stu
dy demonstrates that syphilis is common among inmates in Maputo and th
at risk behaviours for STD transmission exist within Maputo prisons. T
here is a need for STD screening and treatment programmes within priso
ns in Mozambique and the introduction of educational interventions, in
cluding condom promotion.
