AbstractObjectivesUse of Psychoactive substances by young people poses an important public health threat despite mass campaigns and education. There have been documentations of rise in prevalence and use of psychoactive substances by Nigerian adolescents in urban areas of Nigeria. Few reports exist on in-school adolescents in rural areas, and differences in their sociodemographic profile such as public/private school attendance, day/boarding status and socioeconomic status of students. The study determined the rate and sociodemographic profile of psychoactive substance use among secondary school students in selected rural communities in Anambra state, Nigeria.MethodsThis was a cross-sectional study in which multistage sampling was used to select 494 students from selected secondary schools in Anambra state. Data on age, gender, socioeconomic status, student status, school category, alcohol, tobacco and intravenous drug use were obtained using pretested semi-structured questionnaires. Analysis of data was done using IBM SPSS statistics software version 20.0, frequency, percentages and means were calculated, with cross-tabulation done for variables (Chi-square and Fishers exact test where applicable). Level of significance for tests of association set at 5%.ResultsA total of 494 participants were studied of which 48.8% (n=241) were males. The mean age was 14.5 ± 1.8 years. The prevalence of lifetime use of psychoactive substance was 22.5%. Prevalence for individual substances were 21.9% (n=108), 1.8% (n=9) and 0.8% (n=4) respectively for alcohol, tobacco and illicit intravenous drugs. Neither gender {6 males (2.5%), 3 females (1.2%), p=0.890}, age {10–13 years (1.3%), 14–16 years (2.1%), >16 years (1.7%), p=0.329}, student status {day (2.6%), boarding (1.2%), p=0.320}, social class {upper (0.9%), middle (0.6%), lower (3.1%), p=0.208 } nor school category {private (1.5%), public (2.1%), p=0.742} of students was significantly associated with smoking and respectively. More males (73/241=30.3%, p<0.001) took alcohol than females (35/253 = 13.8%) and this was statistically significant. Participants from the lower socioeconomic class (30.3%, p<0.001) had a significantly higher rate of alcohol consumption than those from the upper (11.8%) and middle classes (16.7%) respectively. Higher rate was noted among those who attended public schools (30.8%, p<0.001) compared to those who attended private schools (13.8%). Day students (30.2%, p<0.001) indulged more in alcohol than boarding students (14.3%). There was no association between either the class (junior=22.5%, senior=21.3%, p=0.759) or age of participants (10–13 years=20.7%, 14–16 years=20.1%, >16 years=33.3%, p=0.071) and alcohol consumption. No association was found between age (0.7%, 1.1%, p=1.000), gender (male=1.2%, female=0.4%, p=0.362), social class (lower=1.3%, upper=0.9%, p=0.443), student status (day=0.9%, boarding=0.8%, p=1.000), school category (junior=0.8%, senior=0.8%, p=1.000) and intravenous drug use.ConclusionsThe rate of about 22% alcohol use by secondary school students in rural south eastern Nigeria, which is strongly associated with male gender, low socioeconomic status, day student status and public school attendance is high.
