'The relation between SES and smoking patterns is complex involving cumulative and multiple effects across the human life course, possibly extending from one generation to the next.' Gilman et al 2003 1 p807

Low socioeconomic status (SES) groups have substantially higher smoking rates than the overall population, both in Australia and internationally (see Section 9.1). Higher smoking rates among low-SES groups are associated with a web of interacting physiological, psychological, social, economic, commercial, and cultural factors,2 including:

  • nicotine exposure in utero and during childhood3-6
  • parental and peer relationships and modelling7-16
  • lower achievement and satisfaction at school16-18 and lower educational attainment in adulthood19-21
  • stress,22 , 23 mental illness,24-29 and substance use/dependence30
  • a greater likelihood of belonging to a priority population among whom smoking is more common, such as Aboriginal and Torres Strait Islander peoples, people experiencing incarceration, or LGBTQI+ people
  • social isolation31
  • for minority groups, experiencing discrimination.32-34
  • a lesser tendency to consider and value future outcomes35-38
  • the endorsement of beliefs that minimise or discount the risks of smoking39
  • workplaces40 and social circles41 that normalise smoking
  • job loss42 and financial stress43
  • a lower likelihood of working indoors44-46
  • living in a disadvantaged neighbourhood47-50 or low-income housing51
  • representations of smoking in popular culture52-55
  • a history of targeted and intensive marketing56-60
  • less success in maintaining cessation, despite being just as likely to make a quit attempt and to use cessation aids (see Section 9.8)

The above factors vary in importance in explaining socio-economic disparities at different developmental stages61 and at different stages in the tobacco addiction cycle.1 , 61 As with other aspects of social disadvantage, many factors driving tobacco-related disparities originate in childhood62-67 and accumulate throughout the individual’s life.64 , 68-70 It is also important to consider heterogeneity within groups, and that possessing multiple attributes that are associated with high smoking prevalence (for example, belonging to a priority group and having a lower education level) may interact and further increase a person’s risk of smoking.71 , 72

While a wealth of information is available on associations between social disadvantage and tobacco use,73-75 understanding the causal mechanisms underlying these associations is more challenging.76 Nonetheless, recent studies suggest that some of these factors can causally impact a person’s risk of smoking. For example, a large study in the UK found that more years of education leads to reduced likelihood of smoking uptake, and reduced heaviness of smoking and greater likelihood of quitting among smokers.19 Another UK study suggests that the relationship between disadvantage and smoking uptake can largely be explained by parental modelling of smoking. That is, reducing disadvantaged children’s exposure to smoking may largely reduce future disparities in tobacco use.77

Figures 9.7.1 and 9.7.2 show how a variety of physiological, psychological and sociological factors may maintain socio-economic disparities in smoking uptake and smoking cessation.
