The EUREST-PLUS ITC Europe surveys aim to evaluate the impact of the European Union's Tobacco Products Directive (EU TPD) implementation within the context of the WHO FCTC. This article describes the methodology of the 2016 (Wave 1) and 2018 (Wave 2) International Tobacco Control 6 European (6E) Country Survey in Germany, Greece, Hungary, Poland, Romania and Spain; the England arm of the 2016 (Wave 1) and 2018 (Wave 2) ITC 4 Country Smoking and Vaping (4CV) Survey; and the 2016 (Wave 10) and 2017 (Wave 11) ITC Netherlands (NL) Survey. All three ITC surveys covering a total of eight countries are prospective cohort studies with nationally representative samples of smokers.
In the three surveys across the eight countries, the recruited respondents were cigarette smokers who smoked at least monthly, and were aged 18 and older. At each survey wave, eligible cohort members from the previous waves were retained, regardless of smoking status, and dropouts were replaced by a replenishment sample.
Retention rates between the two waves of the ITC 6E Survey by country were 70.5% for Germany, 41.3% for Greece, 35.7% for Hungary, 45.6% for Poland, 54.4% for Romania and 71.3% for Spain. The retention rate for England between ITC 4CV1 and ITC 4CV2 was 39.1%; the retention rates for the ITC Netherlands Survey were 76.6% at Wave 10 (2016) and 80.9% at Wave 11 (2017).
The ITC sampling design and data collection methods in these three ITC surveys allow analyses to examine prospectively the impact of policy environment changes on the use of cigarettes and other tobacco products in each country, to make comparisons across the eight countries.
EUREST-PLUS ITC欧洲调查旨在评估欧盟烟草产品指令（EU TPD）在世界卫生组织《烟草控制框架公约》（WHO FCTC）背景下的实施影响。本文描述了2016年（第1波）和2018年（第2波）在德国、希腊、匈牙利、波兰、罗马尼亚和西班牙开展的国际烟草控制六国（6E）调查；2016年（第1波）和2018年（第2波）ITC四国吸烟与电子烟使用（4CV）调查中的英格兰部分；以及2016年（第10波）和2017年（第11波）ITC荷兰（NL）调查。这三项ITC调查覆盖了总共八个国家，均为对具有全国代表性的吸烟者样本进行的前瞻性队列研究。
在这八项涵盖八个国家的调查中，招募的受访者为每月至少吸烟一次且年龄在18岁及以上的吸烟者。在每次调查波次中，前一波次符合条件的队列成员无论吸烟状况如何均予以保留，退出者由补充样本替代。
ITC 6E调查两轮之间各国的保留率分别为：德国70.5%、希腊41.3%、匈牙利35.7%、波兰45.6%、罗马尼亚54.4%、西班牙71.3%。ITC 4CV1和ITC 4CV2之间英格兰的保留率为39.1%；ITC荷兰调查的保留率在第10波（2016年）为76.6%，在第11波（2017年）为80.9%。
这三项ITC调查中的抽样设计和数据收集方法使分析能够前瞻性地考察政策环境变化对各国香烟及其他烟草产品使用的影响，并在这八个国家之间进行比较。
