*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 at all in the past 30 days ”; daily use (self‐declared current) was defined operationally as: “smoke every day”; daily use in the past week was defined operationally as: “smoked cigarettes on each of the 7 days preceding data collection”; daily use in the past month was defined operationally as: “smoked⩾1 cigarette each day in the past 30 days”; non‐daily use in the past month was defined operationally as: “smoked ⩾1 cigarette in the past 30 days, but not daily”.
†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.
||Two reports74,75 were based on the 1989 US Teenage Attitudes and Practices Survey. When estimates for duplicate age and/or smoking history strata were available, only Moss et al75 was considered in the calculation of summary estimates. Estimates of the lifetime prevalence of cessation attempts among adolescents reporting any use in the past month for duplicate age strata as reported by Allen et al74 were as follows: 86 among 12–18 year olds; 92 among 12–13 year olds; 87 among 14–15 year olds; 85 among 16–18 year olds.
¶This estimate excluded students who reported physician‐diagnosed asthma.
**Excluded from the calculation of summary estimates because a more inclusive aggregate estimate is available for this study.
