Our study analyzes the most recent national representative survey data on tobacco consumption among adults in Burking Faso and our findings suggest that tobacco consumption is higher than what was reported from the 2011 DHS survey [9]. It is not possible to compare our findings with others such as the age-standardized prevalence of daily smoking from 2015, which considers daily smoking instead of any current smoking, and found the age-standardized prevalence of daily smoking for 2015 women to be 4.2% and for men to be 12.5% [4].
From the 2006 to 2013 the government of Burkina Faso has carried out national tobacco control programs. Laws regulate tobacco consumption health care facilities, educational facilities, government facilities and indoor offices. Additionally, Burkina Faso has national bans on direct advertising of tobacco products on billboards and outdoor advertising as well as on national tv or radio.5 In addition, an addiction center was recently opened in the largest hospital in the country. Despite national action to decrease tobacco use since the WHO FCTC took effect on October 2006, Burkina Faso continues to have higher tobacco consumption than other countries in the region [5, 9, 16]. The results from our analyses of STEPS data, as well as the 2011 DHS data show that Burkina Faso’s smoking prevalence in men is higher than 7 of 9 other countries in West Africa and prevalence of SLT in Burkina Faso is higher than 9 of 10 other countries in West Africa [9].
Young people are the main consumers of tobacco in Burkina Faso. Our findings show that nearly one of third of young people aged 25 – 34 years-old reported smoking tobacco and that prevalence decreases with age. In pooled data from 30 SSA countries, age is associated with tobacco consumption, however, both smoking and SLT use increase with age [9]. However, analyses of STEPS data from Kenya also found that the majority of smokers were in younger age groups [17]. Earlier smoking initiation is major public health concern. The average age of smoking initiation among adults in Burkina Faso was 20.9 years of age, highlighting the importance of tobacco prevention policies to address people in younger age groups [12]. Global Youth Tobacco Survey carried out in two cities in Burkina Faso in 2009 found that about 11,9% of boys from 13 to 15 years old in Ouagadougou and 6.0% in Bobo-Dioulasso were currently tobacco smokers [18-19]. While youth smoking has decreased between 2001 and 2009 in both of these cities, the prevalence of use of other tobacco products increased as did youth reports of exposure to second hand smoke at home in Bobo Dioulasso [18].
In our study smoking was also significantly associated with gender and alcohol consumption, but not to location of residence. In various other SSA countries tobacco use is higher in men than in women [9], likely related to differing social norms about gender and tobacco use. Alcohol consumption and tobacco use was also linked in Kenya’s STEPS survey [17], among other studies. The combination of those two risk factors may contribute to future increases of NCDs in Burkina Faso. Our study did not find any association between smoking, education or employment status, while other studies from SSA found that men and women from rural areas, or those with lower educational levels smoke more than those from urban areas [9].
According to our findings, SLT is more frequently used by women and among those living in rural areas of Burkina Faso. Although SLT is less prevalent than smoking, it presents an important public health problem due to its association with many diseases such as cancers (i.e. mouth, pharynx and esophagus) and ischemic heart disease [13]. Health effects of SLT vary by region, related to the types of tobacco that are used in those regions [20]. In sub Saharan Africa few studies focus on the health effects of SLT [21-22]. In general, women SLT users are exposed to multiple health risk such as pregnancy complications (e.g. placenta praevia, placental abruption, and pre-eclampsia) [23]. In this study we did not estimate SLT consumption during pregnancy. A study published in 2017, however, found that the prevalence of SLT during pregnancy in Burkina Faso was 2.8%. This prevalence is higher compared to other Africa regions (1.7%), but lower than in Sierra-Leone (4.6%) [23]. Even at national level scale, as shown in Figure 2, important differences were observed between the regions. Therefore, further and more advanced spatial analysis of tobacco consumption is needed to better guide health care prevention program.
Concerning the limitations of this study we report here the results of the first nationally representative survey on the prevalence and risk factors for tobacco consumption in Burkina Faso. The first limitation stems from the cross-sectional nature of the data that limits the possibility of deriving causal inferences. The second one is that tobacco and alcohol consumption were obtained during interview and is therefore dependent on the faith of the participants. There is therefore both a risk of memory bias and social desirability. It can therefore be estimated that the numbers and prevalence obtained in this survey underestimate the actual consumption. The last point is that some well-known risk factors for tobacco consumption were not included in the study because data on these variables have not been collected during the STEPS survey. Part of such variables is the socio-economic status. Given the study design (cluster sampling design) and the sample size the results of this study can be extended to the whole of Burkina Faso.
Based on the results of this study important preventive measure need to be taken to reduce tobacco consumption in Burkina Faso, with targeted approaches to sections of the population most affected by different types of tobacco use. In general, efforts should target tobacco use in youth, smoking among men and SLT consumption among women and in rural areas.
