Are schools a good setting for adolescent sexual health promotion in rural Africa? A qualitative assessment from Tanzania.

African adolescents are at high risk of poor sexual health. School-based interventions could reach many adolescents in a sustainable and replicable way, if enrolment, funding and infrastructure are adequate. This study examined pupils', recent school leavers', parents' and teachers' views and experiences of rural Tanzanian primary schools, focusing on the implications for potential sexual health programmes. From 1999 to 2002, participant observation was conducted in nine villages for 158 person-weeks. Half of Year 7 pupils were 15-17 years old, and few went on to secondary school, suggesting that primary schools may be a good venue for such programmes. However, serious challenges include low enrolment and attendance rates, limited teacher training, little access to teaching resources and official and unofficial practices that may alienate pupils and their parents, e.g. corporal punishment, pupils being made to do unpaid work, forced pregnancy examinations, and some teachers' alcohol or sexual abuse. At a national level, improved teacher training and supervision are critical, as well as policies that better prevent, identify and correct undesired practices. At a programme level, intervention developers need to simplify the subject matter, introduce alternative teaching methods, help improve teacher-pupil and teacher-community relationships, and closely supervise and appropriately respond to undesired practices.

A process evaluation of a school-based adolescent sexual health intervention in rural Tanzania: the MEMA kwa Vijana programme.

This study is a process evaluation of the school component of the adolescent sexual health programme MEMA kwa Vijana (MkV), which was implemented in 62 primary schools in rural Mwanza, Tanzania from 1999 to 2001. The MkV curriculum was a teacher-led and peer-assisted programme based on the Social Learning Theory. Process evaluation included observation of training sessions, monitoring and supervision, annual surveys of implementers, group discussions and 158 person-weeks of participant observation. Most teachers taught curriculum content well, but sometimes had difficulty adopting new teaching styles. Peer educators performed scripted dramas well, but were limited as informal educators and behavioural models. The intervention appeared successful in addressing some cognitions, e.g. knowledge of risks and benefits of behaviours, but not others, e.g. perceived susceptibility to risk. MkV shared the characteristics of other African school-based programmes found to be successful, and similarly found significant improvements in self-reported behaviour in surveys. However, a substantial proportion of MkV survey self-reports were inconsistent, there was no consistent impact on biological markers and extensive process evaluation found little impact on several key theoretical determinants of behaviour. Improvements in self-reported survey data alone may provide only a very limited-and perhaps invalid-indication of adolescent sexual health programme success.

"A bit more truthful": the validity of adolescent sexual behaviour data collected in rural northern Tanzania using five methods.

OBJECTIVE: To assess the validity of sexual behaviour data collected from African adolescents using five methods. METHODS: 9280 Tanzanian adolescents participated in a biological marker and face to face questionnaire survey and 6079 in an assisted self-completion questionnaire survey; 74 participated in in-depth interviews and 56 person weeks of participant observation were conducted. RESULTS: 38% of males and 59% of females reporting sexual activity did so in only one of the two 1998 questionnaires. Only 58% of males and 29% of females with biological markers consistently reported sexual activity in both questionnaires. Nine of 11 (82%) in-depth interview respondents who had had biological markers provided an invalid series of responses about sex in the survey and in-depth interview series. Only one of six female in-depth interview respondents with an STI reported sex in any of the four surveys, but five reported it in the in-depth interviews. CONCLUSION: In this low prevalence population, biological markers on their own revealed that a few adolescents had had sex, but in combination with in-depth interviews they may be useful in identifying risk factors for STIs. Self-reported sexual behaviour data were fraught with inconsistencies. In-depth interviews seem to be more effective than assisted self-completion questionnaires and face to face questionnaires in promoting honest responses among females with STIs. Participant observation was the most useful method for understanding the nature, complexity, and extent of sexual behaviour.

The sexual health of pupils in years 4 to 6 of primary schools in rural Tanzania.

BACKGROUND/OBJECTIVES: There is an urgent need for effective interventions to improve the sexual and reproductive health of adolescents. Reliable data on the sexual health of adolescents are needed to guide the development of such interventions. The aim was to describe the sexual health of pupils in years 4 to 6 of 121 rural primary schools in north western Tanzania, before the implementation of an innovative sexual health intervention in 58 of the schools. METHODS: A cross sectional survey of primary school pupils in rural Tanzania was carried out. The study population comprised pupils registered in years 4 to 6 of 121 primary schools in 20 rural communities in 1998. Basic demographic information was collected from all pupils seen. Those born before 1 January 1985 (aged approximately 14 years and over) were invited to participate in the survey, and asked about their knowledge and attitudes towards sexual health issues, and their sexual experience. A urine specimen was requested and tested for HIV, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and, for females, pregnancy. RESULTS: 9283 pupils born before 1 January 1985 were enrolled and provided demographic information and a urine sample. Male pupils were significantly older than females (mean age 15.5 years v 14.8 years, p<0.001), but all other demographic characteristics were similar between the sexes. 14 (0.2%) of the enrolled pupils (four male and 10 female) were HIV positive, 83 (0.9%) were positive for CT, and 12 (0.1%) for NG. 32 female pupils (0.8%) were positive by pregnancy test. Sexual experience was reported by one fifth of primary school girls, and by almost half of boys. Only 45/114 (39%) girls with biological markers of sexual activity reported having had sex. CONCLUSIONS: HIV, CT, NG, and pregnancy were present though at relatively low levels among pupils in years 4 to 6 of primary school. A high proportion of pupils with a biological marker of sexual activity denied ever having had sex. Alternative ways of collecting sensitive data about the sexual behaviour of school pupils should be explored.
