Objective: To test the effects of an HIV/AIDS education program. Desig
n: A quasi-experimental, nested cross-sectional design including basel
ine and 6-month follow-up surveys. Schools, stratified according to lo
cation, were randomly assigned to intervention (n = 6) or comparison c
onditions (n = 12).Setting: Public primary schools in Arusha and Kilim
anjaro regions, Tanzania. Participants: A total of 2026 sixth and seve
nth grade pupils (average age, 14.0 years) participated at baseline (8
5%) and 1785 at follow-up. Intervention: The program was designed to r
educe children's risk of HIV infection and to improve their tolerance
of and care for people with AIDS. Local teachers and health workers at
tended a 1-week training workshop before implementing the program over
a 2-3-month period (averaging 20 school hours per class). Main outcom
e measures: Self-reported exposure to AIDS information, communication
regarding AIDS; AIDS knowledge, attitudes towards people with AIDS, at
titudes towards having sexual intercourse, subjective norms regarding
sexual intercourse, and intention to engage in sexual intercourse. Res
ults: Following this program, intervention pupils reported significant
ly higher scores for the following outcome measures than pupils attend
ing the comparison schools: AIDS information (13.1 versus 10.5; P = 0.
0001), AIDS communication (10.9 versus 7.8; P = 0.0001) AIDS knowledge
(14.5 versus 11.5; P = 0.0001), attitudes towards people with AIDS (9
.0 versus 6.7; P = 0.0008), subjective norms (45.5 versus 43.9; P = 0.
011), and intention (1.3 versus 1.4; P = 0.020). No program effect was
seen for attitudes towards sexual intercourse (47.0 versus 46.3, P =
0.44). Conclusions: These results indicate that it is feasible and eff
ective to provide AIDS education for Tanzanian primary school children
.
