To estimate the proportion of smokers that could potentially have been prevented from smoking by limiting the amount of pocket money received by Chinese adolescents.
Cross-sectional study.
Current smoking, ever smoking and the amount of pocket money were determined through self-administered questionnaires among 12,708 adolescents (aged 12-18 years) from 21 schools in Shanghai, China.
Adjusted odds ratios for current smoking ranged from 2.0 [95% confidence interval (CI) 1.5-2.7] for adolescents receiving 200-399 Reminbin (RMB)/month as pocket money to 6.5 (95% CI 3.3-12.7) for those receiving ≥1000 RMB/month, compared with those receiving <200 RMB/month. The crude population-attributable risk percentage (PAR%) due to higher pocket money (≥200 RMB/month) for current smoking was 50.4% (95% CI 42.2-57.4), and adjusted PAR% was 43.3% (95% CI 30.7-53.1).
Approximately half of current smokers may have been prevented from smoking if pocket money was limited to <200 RMB/month among Chinese adolescents. An even larger proportion could have been prevented from smoking if pocket money was reduced further. It is recommended that future intervention programmes should target parents to reduce the amount of pocket money in China.
通过限制中国青少年收到的零花钱数额，估计有多少吸烟者可以避免吸烟。
横断面研究。
在中国上海的 21 所学校中，通过对 12708 名 12-18 岁青少年进行自我管理的问卷调查，确定了当前吸烟、曾经吸烟和零花钱数额。
与每月收到零花钱<200 人民币（RMB）的青少年相比，零花钱为 200-399 RMB/月的青少年当前吸烟的调整优势比（OR）为 2.0（95%置信区间（CI）1.5-2.7），零花钱为≥1000 RMB/月的青少年当前吸烟的调整 OR 为 6.5（95% CI 3.3-12.7）。由于零花钱较高（≥200 RMB/月）导致当前吸烟的粗人群归因风险百分比（PAR%）为 50.4%（95% CI 42.2-57.4），调整后的 PAR%为 43.3%（95% CI 30.7-53.1）。
如果限制中国青少年每月零花钱<200 RMB，大约有一半的当前吸烟者可能会避免吸烟。如果进一步减少零花钱，可能会有更多的人避免吸烟。建议未来的干预计划应针对父母，以减少中国的零花钱数额。
