Determinants of waterpipe smoking among high school students in Jakarta, Indonesia.

Objectives The study aimed to examine factors associated with past 30 days waterpipe use among high school students in Jakarta, Indonesia. Methods We surveyed a multistage cluster random sample of 1,318 students of grade 10th and 11th from 14 schools in Jakarta. Multiple logistic regressions were employed to examine the association between past 30 days waterpipe use with sociodemographic characteristics, cigarettes smoking status, parental and peer use, availability and affordability. Results Of 1,318 participants, 3.3% of female and 8.4% of male currently smoked waterpipe. Multivariate analysis revealed that current waterpipe use was significantly associated with family use (AOR: 4.844, 95% CI: 1.225-19.151), friend use (AOR: 2.554, 95% CI: 1.424-4.582), and availability (AOR: 2.143, 95% CI: 1.127-4.076). Being current smokers were six times more likely (AOR: 6.055, 95% CI: 3.123-11.739) to use waterpipe in the past 30 days. Conclusions The finding suggests that smoking by a family member, friends, use of conventional cigarettes, and availability are significantly associated with increased probability of current waterpipe used among adolescents.
