Impact of the MEMA kwa Vijana adolescent sexual and reproductive health interventions on use of health services by young people in rural Mwanza, Tanzania: results of a cluster randomized trial.
PURPOSE: To assess the impact of an adolescent sexual health intervention on the use of health services by young people in Tanzania. METHODS: Twenty communities, including 39 health facilities, were randomly allocated to the intervention or comparison arm. Health workers from the intervention arm were trained in the provision of youth-friendly health services, as part of a package of interventions. Independent process evaluations were conducted in health facilities, and simulated patients visited clinics using sexual and reproductive health problem scenarios. The impact on health facility attendances were assessed in 1998 (baseline) and 1999-2001. Reported sexually transmitted infection (STI) symptoms and use of health services were evaluated in young people in the trial cohort. RESULTS: The mean monthly attendance for STI symptoms per health facility, per month was .5 for young males and 1.0 for young females at baseline. Attendance by young males was greater in the intervention communities in 1999-2000 after adjustment for baseline differences (p = .005), and this difference increased over time (p-trend = .022). The mean difference in attendance was however relatively modest, at 1.1 per month in 2001 after adjustment for baseline (95% CI: .5, 1.7). There was weaker evidence of an intervention effect on attendance by young women (p = .087). Few condoms were distributed, although a greater number were distributed in intervention facilities (p = .008). Generally, intervention health workers tended to be less judgmental and provided more comprehensive information. CONCLUSIONS: Training staff to provide more youth-friendly health services can increase the utilization of health services for suspected STIs by young people, especially among young men
Biological and behavioural impact of an adolescent sexual health intervention in Tanzania: a community-randomized trial.
OBJECTIVE: The impact of a multicomponent intervention programme on the sexual health of adolescents was assessed in rural Tanzania. DESIGN: A community-randomized trial. METHODS: Twenty communities were randomly allocated to receive either a specially designed programme of interventions (intervention group) or standard activities (comparison group). The intervention had four components: community activities; teacher-led, peer-assisted sexual health education in years 5-7 of primary school; training and supervision of health workers to provide 'youth-friendly' sexual health services; and peer condom social marketing. Impacts on HIV incidence, herpes simplex virus 2 (HSV2) and other sexual health outcomes were evaluated over approximately 3 years in 9645 adolescents recruited in late 1998 before entering years 5, 6 or 7 of primary school. RESULTS: The intervention had a significant impact on knowledge and reported attitudes, reported sexually transmitted infection symptoms, and several behavioural outcomes. Only five HIV seroconversions occurred in boys, whereas in girls the adjusted rate ratio (intervention versus comparison) was 0.75 [95% confidence interval (CI) 0.34, 1.66]. Overall HSV2 prevalences at follow-up were 11.9% in male and 21.1% in female participants, with adjusted prevalence ratios of 0.92 (CI 0.69, 1.22) and 1.05 (CI 0.83, 1.32), respectively. There was no consistent beneficial or adverse impact on other biological outcomes. The beneficial impact on knowledge and reported attitudes was confirmed by results of a school examination in a separate group of students in mid-2002. CONCLUSION: The intervention substantially improved knowledge, reported attitudes and some reported sexual behaviours, especially in boys, but had no consistent impact on biological outcomes within the 3-year trial period
From trial intervention to scale-up: costs of an adolescent sexual health program in Mwanza, Tanzania.
OBJECTIVE: To estimate annual costs of a multifaceted adolescent sexual health intervention in Mwanza, Tanzania, by input (capital and recurrent), component (in-school, community activities, youth-friendly health services, condom distribution), and phase (development, startup, trial implementation, scale-up). STUDY DESIGN: Financial and economic providers' costs and intervention outputs were collected to estimate annual total and unit costs (1999-2001). The incremental financial budget projects funding requirements for scale-up within an integrated model. RESULTS: The 3-year economic costs of trial implementation were US dollars 879,032, of which approximately 70% were for the school-based component. Costs of initial development and startup were relatively substantial ( approximately 21% of total costs); however, annual costs per school child dropped from US dollars 16 in 1999 to US dollars 10 in 2001. The incremental scale-up cost is approximately 1/5 of ward trial implementation running costs. CONCLUSIONS: Annual costs can reduce by almost 40% as project implementation matures. When scaled up, only an additional US dollars 1.54 is needed per pupil per year to continue the intervention
