戒烟率如何因年龄、性别和社会等级而不同？来自英国人口调查的发现
2013/11/13
摘要
目的：评估以年龄、性别、社会等级为函数的长期戒烟发生率以及他们之间的相互作用。
设计和地点：对来自英国吸烟者的人群代表性样本进行的横断面调查。
参加者：共24094名曾吸烟者（21岁≤年龄≤60岁）参加到2006年11月～2011年2月的家庭调查中。
检测：计算每个年龄的长期戒烟者（>1年）和曾吸烟者的比例。采用回归分析建立年龄-戒烟率关联模型，戒烟率改变根据n岁时的戒烟率与至n-1岁所有年龄戒烟率的比值计算。对整个样本及分层后样本（分层因素：性别、社会等级）进行分析，并评估这个变量之间的相互作用。
发现：需要采用新发率的立方值以进行数据分析。21～30岁的估计戒烟发生率为1.5% (95% CI: 1.0%-2.0%)，31～50岁的估计戒烟发生率为0.3% (95% CI: 0.2%-0.5%)，51～60岁的估计戒烟发生率为1.2% (95% CI: 0.7%-1.7%)。年龄与性别和社会等级存在相互作用：女性和社会等级高的吸烟者戒烟发生率高于男性和社会等级低的吸烟者，特别是在年轻成年吸烟者中。
结论：英国戒烟情况显示年轻和老年成年戒烟率高于中年人。女性和社会等级高的吸烟者戒烟发生率高于男性和社会等级低的吸烟者，尤其是在年轻成年吸烟者中。

Abstract
AIMS: To assess the incidence of long-term smoking cessation as a function of age, gender, social grade and their interactions.
DESIGN AND SETTING: Cross-sectional surveys of population representative samples of smokers in England.
PARTICIPANTS: A total of 24 094 ever smokers (≥21 and ≤60 years of age) participating in household surveys between November 2006 and February 2011.
MEASUREMENTS: The ratio of long-term (>1 year) ex-smokers to ever-smokers was calculated for each age. Regression analyses were used to model the association between age and quit ratio, with the change in quit ratio by year of age n years versus all years up to n-1 years, yielding an estimate of the quitting incidence at that age. Analyses were conducted for the entire sample and then for the sample stratified by gender and social grade, and interactions assessed between these variables.
FINDINGS: The incidence of A cubic trend was needed to fit the data. The estimated quitting incidence between ages 21 and 30 was 1.5% (95% CI: 1.0%-2.0%), between 31 and 50 it was 0.3% (95% CI: 0.2%-0.5%) and between 51 and 60 it was 1.2% (95% CI: 0.7%-1.7%). Age interacted with gender and social grade: women and smokers from higher social grades had a higher incidence of quitting than men and those from lower social grades specifically in young adulthood.
CONCLUSIONS：smoking cessation in England appears to be greater in young and old adults compared with those in middle age. Women and higher social grade smokers show a greater incidence of quitting than men and those from lower social grades specifically in young adulthood.
