Within the project, the effectiveness of the school-based prevention program “Unplugged” was evaluated though a cluster RCT with two arms: the experimental group and the Usual Curriculum control group.MethodsThe study involved federal schools of the entire territory of Nigeria. Assuming alpha 0.05, power 0.80, prevalence of use in the control arm 14.6% and in the intervention arm 10.2%, 45 pupils per class, ICC 0.025, the estimated sample size needed was 1943 pupils per group. This corresponded to 14 schools per arm. To overcome possible drop-outs, the number of schools to be randomized was enlarged to 16 per arm. The randomization took place by zone. The number of schools to be randomized in each zone was decided based on the population size of the zones. Extraction and randomization of the schools were performed at the central level, in OED Institute in Torino, Italy. All the 32 schools and 96 classes participated both in the baseline and in the follow-up survey. A self-completed anonymous questionnaire was created ad hoc for the surveys. To preserve confidentiality, the questionnaires were labelled with a 9-digit individual code self-generated by the student.Response to Drugs and Related Organised Crime in Nigeria (FED/2012/306-744) (NGAV16)1.

Therefore, the implementation of Unplugged on a larger scale in the country can be supported, with the attention of focusing on younger adolescents.Outcome Overall 10-14 years AOR* (95% CI) AOR* (95% CI) Last month cigarette smoking   at least once 0.84 (0.56-1.27) 0.61 (0.21-1.73) at least 6 times: regular smoking 0.54 (0.28-1.06) - Last month alcohol drinking   at least once 0.82 (0.69-0.98) 0.71 (0.53-0.94) at least 6 times: regular drinking 0.74 (0.58-0.94) 0.58 (0.38-0.86) at least 20 times: daily drinking 0.61 (0.40-0.95) 0.83 (0.38-1.82) Last month marijuana use   at least once 0.81 (0.51-1.29) 0.17 (0.03-0.86) at least 6 times: regular use 0.82 (0.46-1.45) - Negative beliefs (high vs middle/low)   on tobacco 1.17 (1.00-1.38) 1.13 (0.89-1.43) on alcohol  1.25 (1.07-1.46) 1.25 (0.99-1.59) on marijuana and drugs 1.15 (0.97-1.35) 1.06 (0.82-1.36) Class climate (good vs medium/bad) 1.35 (1.13-1.63) 1.49 (1.14-1.96) Peers’ prevalence   none/less than half smoke cigarettes 1.39 (1.19-1.62) 1.59 (1.25-2.02) none/less than half drink alcohol 1.34 (1.15-1.56) 1.43 (1.14-1.80) none/less than half use marijuana or drugs 1.19 (1.03-1.39) 1.19 (0.95-1.50) *Multilevel model with zone as first level, adjusted for age, baseline level of the indicator, and zone’s baseline prevalence of tobacco, acohol or marijuana use specific for the indicator.
