Tobacco smoking is an important cause of premature death and morbidity in Denmark. It is therefore important to monitor tobacco consumption. In this paper, tobacco consumption in Denmark is illustrated by two methods: sale of tobacco products and smoking habit surveys.
Data on sale of tobacco products in Denmark were available for the 1920-2010-period. National smoking habit surveys were found through grey-zone literature, a PubMed search and a report on the Danish population's smoking habits. Ten smoking habit surveys were identified from the 1953-2010-period, three of which have data from multiple years and annual surveys from 1969 onwards.
The changes in tobacco consumption found by the two methods were not parallel. Furthermore, there were significant differences between the proportions of smokers found in smoking habit questionnaires from the same year. This difference may be due to changes in cross-border trade, smuggling, smokers' willingness to participate in smoking habit studies, recognition of own smoking and actual tobacco consumption, and differences in the composition of participants in the smoking habit studies both over time and between different studies.
Both sales statistics and surveys have advantages and disadvantages. It may therefore be important to use both when estimating tobacco consumption.
吸烟是丹麦过早死亡和发病的一个重要原因。因此，监测烟草消费情况很重要。在本文中，丹麦的烟草消费情况通过两种方法进行说明：烟草制品销售和吸烟习惯调查。
丹麦1920 - 2010年期间有烟草制品销售数据。通过灰色地带文献、PubMed搜索以及一份关于丹麦人口吸烟习惯的报告找到了全国吸烟习惯调查。从1953 - 2010年期间确定了10项吸烟习惯调查，其中3项有多年数据，1969年起有年度调查数据。
两种方法得出的烟草消费变化并不平行。此外，同一年吸烟习惯调查问卷中吸烟者比例存在显著差异。这种差异可能是由于跨境贸易、走私、吸烟者参与吸烟习惯研究的意愿、对自身吸烟的认知和实际烟草消费的变化，以及吸烟习惯研究参与者构成在不同时间和不同研究之间的差异。
销售统计和调查都有优缺点。因此，在估计烟草消费时同时使用这两种方法可能很重要。
