Regional And Sex-Specific Disparities in Tobacco and E-Cigarette Use Across WHO Regions: A Comparative Analysis of Global Health Surveillance Data
This study analyzes global health surveillance data to reveal significant regional, product-specific, and sex-based disparities in tobacco and e-cigarette use, underscoring the need for tailored, sex-responsive tobacco control strategies and enhanced surveillance of emerging nicotine products.

Tobacco use remains one of the most significant threats to global health, responsible for millions of preventable deaths every year. For decades, public health efforts have focused on the familiar image of the cigarette, yet the landscape of nicotine consumption is far more complex. It includes smokeless products like chewing tobacco, which are deeply woven into the cultural fabric of certain regions, and newer electronic devices that deliver nicotine without combustion. These different forms of tobacco do not affect men and women equally, nor do they appear with the same intensity in every part of the world. Understanding where these products are used, by whom, and how their popularity is shifting is essential for designing effective health policies. Without this detailed map of global habits, efforts to reduce disease and save lives may miss their mark entirely.
A recent analysis of global health data has provided a clearer picture of these disparities, moving beyond simple averages to reveal the distinct patterns of tobacco use across the six major regions of the world. Researchers examined decades of surveillance data to track how many adults smoke cigarettes daily, use electronic cigarettes, or consume smokeless tobacco. They paid close attention to the differences between men and women, not just in how many people use these products, but in the sheer scale of the gap between the sexes. By looking at the data from every corner of the globe, from the Americas to Southeast Asia, the study uncovered that while tobacco use is a universal problem, the specific ways it manifests are deeply local and highly gendered.
The findings reveal a world where the burden of smoking falls heavily and consistently on men. In nearly every region studied, men smoke cigarettes at rates far higher than women. This gap is most pronounced in the Eastern Mediterranean region, where the difference in daily smoking between men and women is so vast that it represents an extreme disparity. In the Western Pacific and European regions, men also lead the way, with daily cigarette smoking rates reaching nearly thirty percent for men, compared to much lower figures for women. Even in regions where overall smoking rates are lower, such as the Americas, the pattern remains the same: men are significantly more likely to be daily smokers than women. This consistency suggests that social and cultural factors driving men to smoke are powerful and widespread, operating similarly across very different societies.
However, the story changes when looking at smokeless tobacco, which includes products like chewing tobacco, snuff, and gutka. Here, the global map looks different. The highest rates of daily smokeless tobacco use are found in Southeast Asia, where more than eleven percent of men and nearly seven percent of women use these products daily. In this region, the use of smokeless tobacco is a major public health issue, distinct from the cigarette problem seen elsewhere. Interestingly, in the Western Pacific region, the trend reverses slightly, with women showing higher rates of smokeless tobacco use than men, a unique exception to the general rule that men use more tobacco in all forms. This highlights that while men generally use more tobacco overall, the specific type of product people choose depends heavily on local traditions and availability.
The rise of electronic cigarettes adds another layer of complexity to the global picture. These devices, which deliver nicotine through vapor rather than smoke, show a different pattern of use compared to traditional cigarettes. The highest rates of daily e-cigarette use are found in the Western Pacific region, where nearly eight percent of men use them daily. In contrast, use in Southeast Asia and Africa is so low that it barely registers in the data. Unlike the steady, high rates of cigarette smoking among men, the use of e-cigarettes varies wildly from one region to another, suggesting that their adoption is driven by specific market conditions and regulations rather than a single global trend. The data also hints that while cigarette smoking is slowly declining in many places, e-cigarette use may be rising in some areas, particularly among men in Europe and the Americas.
Looking ahead, the analysis suggests that the decline in traditional cigarette smoking is likely to continue, especially among women, but the gap between men and women will persist. Men are projected to remain the primary users of combustible tobacco across all regions for the foreseeable future. At the same time, the use of e-cigarettes is expected to grow modestly in several regions, potentially replacing some cigarette use but also creating new populations of nicotine users. This shifting landscape means that public health strategies cannot rely on a one-size-fits-all approach. In the Western Pacific and Europe, the focus must remain on reducing the high rates of cigarette smoking among men. In Southeast Asia, the priority must be addressing the heavy burden of smokeless tobacco, which affects both men and women but remains a distinct challenge.
The study underscores that effective tobacco control requires a nuanced understanding of local realities. A strategy that works to reduce cigarette smoking in Europe may have little impact on the smokeless tobacco habits of Southeast Asia. Similarly, policies that ignore the growing use of e-cigarettes in certain regions risk missing a significant portion of the problem. By breaking down the data by region, product type, and sex, researchers have shown that the fight against tobacco is not a single battle but a series of distinct campaigns, each requiring its own tactics. As the world moves toward 2030, with goals to reduce premature deaths from non-communicable diseases, these detailed insights are vital. They remind us that to save lives, we must first understand the specific habits of the people we aim to protect, recognizing that for many men around the world, tobacco use remains a deeply entrenched part of daily life.
