To investigate whether pocket money amount and socio-economic status are risk factors for smoking in 14 and 15 year old children.
This was a national cross-sectional survey of 4th form students who answered an anonymous self-administered questionnaire in November 2000. Socio-economic status was determined from the Ministry of Education school socio-economic deciles.
Questionnaires from 14793 girls and 14577 boys were analysed. Socioeconomic status (SES) was inversely associated with smoking prevalence in girls only (p<0.0001). Students in low SES decile schools received greater amounts of pocket money than those in high SES decile schools (p<0.0001). Compared with students who received $1-10 in the last 30 days, for students receiving pocket money >$30, $21-30, or $11-20, the adjusted relative risks for smoking > or = monthly were 1.73 (95% CI 1.61, 1.85), 1.48 (1.35, 1.62), and 1.15 (1.03, 1.28) in girls, and 1.57 (1.46, 1.70), 1.32 (1.19, 1.46), and 1.11 (1.00, 1.23) in boys, respectively. The proportion of smokers purchasing cigarettes increased with amount of pocket money received in the last 30 days (p<0.0001).
Cigarette smoking is positively related to pocket money amount in adolescents. This finding has important public health significance, but further research is required to determine if the association is causal.
调查零花钱数额和社会经济地位是否为14至15岁儿童吸烟的风险因素。
这是一项针对2000年11月回答匿名自填问卷的四年级学生的全国性横断面调查。社会经济地位由教育部学校社会经济十分位数确定。
对14793名女生和14577名男生的问卷进行了分析。社会经济地位（SES）仅与女生吸烟率呈负相关（p<0.0001）。社会经济地位低十分位数学校的学生比社会经济地位高十分位数学校的学生获得的零花钱更多（p<0.0001）。与过去30天收到1至10美元的学生相比，对于收到零花钱超过30美元、21至30美元或11至20美元的学生，女生每月吸烟≥的调整后相对风险分别为1.73（95%可信区间1.61,1.85）、1.48（1.35,1.62）和1.15（1.03,1.28），男生分别为1.57（1.46,1.70）、1.32（1.19,1.46）和1.11（1.00,1.
