Prevalence and factors influencing substance abuse among secondary school students in Mbeya City, Tanzania.

Résumé

BACKGROUND: Substance abuse among students has far-reaching social, religious, economic, health and demographic consequences, such as unplanned pregnancies, school dropouts, abortions, maternal and newborn mortality, infection risks and other psychological problems. Our study investigated the prevalence of substance abuse among secondary school students in Mbeya City, Tanzania.METHODS: This school-based cross-sectional study was conducted from January to May 2021 among secondary students from Mbeya City, Tanzania. Students completed a self-administered substance use questionnaire. Data were analysed using descriptive statistics.RESULTS: A total of 343 students were requested to participate in the study. However, 300 agreed to indicate 87% response rate. 9.7% (n=59) reported substance use, primarily cannabis, 75% (n=225) and alcohol, 68% (n=204). Friends influenced substance use among 82.7% of users. Reported immediate effects included misbehaviour, 73.7% (n=221) and unprotected sex, 72.3% (n=217). Long-term harms were predominantly brain damage (86.7%). Community education (78%) and media campaigns (76.7%) were suggested to curb use.CONCLUSION: Substance abuse among a sizable minority of Mbeya City secondary school students is driven by peer influence and has detrimental impacts reported by students themselves. Comprehensive education and preventive strategies engaging families, schools and communities are recommended to address this critical youth issue.
