Three hundred seventy-two (63%) of 590 enrollees in nine smoking cessation workshops held over a five-year period responded to a follow-up survey. Outcome data were collected retrospectively for six-month intervals from workshop to follow-up. Forty nine per cent of all enrollees graduated, and 56% of the respondents quit smoking during the program. Nonsmoking rates declined to an average of 25% by the first year post-workshop and remained relatively stable thereafter for periods up to five years.
在五年期间举办的九次戒烟研讨班的590名学员中,有372人(63%)回复了一项随访调查。从研讨班到随访,每隔六个月回顾性收集一次结果数据。所有学员中有49%毕业,56%的受访者在项目期间戒烟。到研讨班结束后的第一年,不吸烟率降至平均25%,此后在长达五年的时间里保持相对稳定。
