Association between anxiety, alcohol, poly-tobacco use and waterpipe smoking: A cross-sectional study in Lagos, Nigeria
Abstract
Background: Waterpipe smoking (WPS) has been reported to have a wide range of damaging health effects on pulmonary and cardiovascular systems. Studies suggest that waterpipe tobacco smoking is associated with reduced harm perceptions, mental health problems and the use of psychoactive substances. We investigate the patterns of use and the association of WPS with anxiety, poly-tobacco and alcohol use in Lagos, Nigeria. Materials and Methods: A cross-sectional study design was used to assess the data from 818 adolescents and adults in Lagos State, Nigeria. An online questionnaire obtained demographic information, waterpipe, e-cigarette, alcohol and other tobacco product use from respondents. Anxiety was assessed using the validated Generalised Anxiety Disorder 7-point scale. Bivariate and multivariate logistic regression analysis was used to identify the factors associated with waterpipe ever-use. P < 0.05 was considered statistically significant. Results: The mean (standard deviation) age of respondents was 23.43 (±3.96), over half were female (55.2%) and a majority had a college diploma or more (88.59%). Among study participants, 18.58% reported waterpipe ever-use. Among ever waterpipe users, 17.33% reported current use (past 30-days), with a majority having smoked waterpipe in a bar or pub. Alcohol use (P < 0.001), e-cigarette ever-use (P: 0.010) and poly-tobacco ever-use (P: 0.030) were significantly associated with higher odds of waterpipe use in the multivariate regression model. Further, there was a lower likelihood of waterpipe ever-use in the bivariate regression model among respondents with mild and moderate to severe anxiety levels than those with normal anxiety levels (P: 0.030); however, this association was no longer significant in the adjusted model. Conclusions: Our findings suggest a relatively high prevalence of WPS in Lagos, Nigeria. Concurrent alcohol consumption, e-cigarette and poly-tobacco use are associated with WPS, and most waterpipe smokers have normal anxiety levels. The Nigerian Government should consider surveillance measures for WPS and a more comprehensive smoke-free policy.
