*Any use in the past month was defined operationally as “smoked ⩾1 cigarette in the past 30 days”, except by the US Department of Health2 where it was defined as “smoked in past month”; daily use (self‐declared current) was defined operationally as: “smoke cigarettes daily at the present time”.
†The Global Youth Tobacco Surveys identified classes to correspond to the target group of adolescents aged 13–15. However, all students in the selected classes were eligible to participate. Therefore adolescents younger than 13 years and older than 15 years could be included. For the age categories ⩽12 years and ⩾16 years we assumed that the lower and upper bounds met the eligibility criteria that study subjects be adolescents aged 10–19.
‡Excluded from the calculation of summary estimate because complete stratum‐specific estimates were available for this study.
§Estimated among the subgroup of adolescents who had smoked ⩾100 cigarettes in their lifetime.
||Estimated among the subgroup of adolescents who had smoked <100 cigarettes in their lifetime.
¶Excluded from summary estimates because a more inclusive aggregate estimate is available for this study.
