The marketing of sweetened and flavoured tobacco in the early 1990s resulted in an upsurge in waterpipe smoking (WPS), mainly among young people and women. Here, we estimate prevalence rates among school-attending adolescents aged 14–19 (girls 52%) for a lifetime experience of WPS and within the last 30 days (WPS < 30 days) and identify influential factors for such smoking in Bissau, Guinea-Bissau. A random sample (N = 2039) was drawn from a class-based register created for 16 schools in Bissau; attending students in June 2017 were invited to respond to a locally adapted Planet Youth questionnaire. Descriptive statistics, odds ratio with 95% confidence interval, and multinomial logistic regression analysis were used to identify influential factors for WPS. The prevalence rates for a lifetime experience of WPS and within < 30 days were high, 17.7% and 15.0%, respectively, with no significant gender difference. For both groups, a multinomial logistic regression analysis identified attending higher grades in school, use of alcohol and being a victim of sexual violence as significant, influential factors. The overlapping of influential factors suggests preventive work against substance abuse should focus on less stigmatising behaviour, such as WPS and firmer implementation of the Framework Convention of Tobacco Control (FCTC).

Balanced medical and criminal justice approaches addressing determinants of alcohol and other drugs (AOD) use are central to achieving the United Nations Sustainable Development Goals 3 and 16. However, data on AOD use in resource-poor settings are characterised by relative paucity and anecdote. This study aimed to describe and analyse AOD use susceptibility and its determinants among school-attending adolescents in the capital Bissau, Guinea-Bissau. Survey data were collected through a locally adapted Planet Youth questionnaire in June 2017 across 16 schools in Bissau. The 2039-strong sample was selected through a multi-stage, random cluster process. Participants’ lifetime alcohol use was 27.3%, smoking 10.8%, and cannabis use 3.6%. In each instance, the ‘15 years and above’ age bracket was the most common initiation period, signifying increased instigation in later adolescence. Subsequent Varimax Principal Component Analysis (PCA) of 312 variables captured data-driven models of AOD use susceptibility, implying imitated, polydrug use among initiates. Linear regression analysis revealed drinking, group violence, male gender, school dismissal and relationship breakdown as explanatory variables. Overlapping predictive variables suggest singular interventions may pre-empt myriad antisocial behaviours. PCA offers alternatives to singular, potentially myopic quantifications of drug use. PCA facilitates the creation of context-sensitive composite variables, enabling the identification of related outcome behaviours relevant to studies’ sociocultural settings.
