The consumption, sales, and output of tobacco products each suggest different areas of intervention for tobacco control. In the era of the tobacco endgame, as increasingly stronger supply-side measures are implemented, multifaceted indicators that assess both supply and/or demand are required. We aimed to estimate the consumption of cigarette and heated tobacco products (HTPs) and sought agreement between the various indicators.
The annual cigarette and HTP consumption in 2014-2020 was calculated using the frequency and intensity of cigarette use from representative surveys of adults and adolescents by sex and age. Sales and output data were acquired from governmental sources. Spearman correlation coefficients and Bland-Altman plots were used to compare the indicators.
Tobacco output, cigarette sales, and cigarette consumption were greatest in 2014. The HTP consumption calculated for 2020 was 292.28 million packs. Cigarette consumption and sales correlated significantly, as did tobacco output and tobacco sales. A Bland-Altman plot comparing the difference between cigarette consumption and sales showed that this difference was largest in 2014, immediately before cigarette prices increased. With the exception of a single year, all cigarette consumption values were within the limits of agreement for cigarette sales and tobacco output.
Our analyses showed agreement between demand-side (tobacco consumption) and supply-side (sales and output) indicators. We recommend using all indicators to monitor the impacts of tobacco control on both demand and supply sides. The systematic use of various indicators is critical to achieve the end of the tobacco epidemic.
烟草制品的消费、销售和产量都表明了控烟干预的不同领域。在烟草终局时代，随着越来越强的供应方措施的实施，需要评估供应和/或需求的多方面指标。我们旨在估计香烟和加热烟草制品（HTPs）的消费，并寻求各种指标之间的一致性。
利用成年人和青少年代表性调查中按性别和年龄划分的香烟使用频率和强度，计算 2014-2020 年香烟和 HTP 的年消费量。销售和产量数据来自政府来源。使用 Spearman 相关系数和 Bland-Altman 图比较指标。
2014 年烟草产量、香烟销售和香烟消费达到最大值。计算得出的 2020 年 HTP 消费量为 2.9228 亿支。香烟消费和销售呈显著相关，烟草产量和香烟销售也是如此。Bland-Altman 图比较香烟消费和销售之间的差异显示，在 2014 年香烟价格上涨之前，这种差异最大。除了一年外，所有香烟消费值都在香烟销售和烟草产量的一致性范围内。
我们的分析表明，需求侧（烟草消费）和供应侧（销售和产量）指标之间存在一致性。我们建议使用所有指标来监测控烟对需求和供应两侧的影响。系统地使用各种指标对于实现烟草流行的终结至关重要。
