van Wijk EC, et al. - Researchers identified factors that prevent lower socioeconomic status (SES) smokers access to smoking cessation support by analyzing 43 papers published before June 2016 relevant to this topic. Using the access to health care framework, they divided barriers into either the abilities of smokers or dimensions of cessation support and one of the successive phases of access to support. They found many barriers were faced by lower SES smokers, all reported in all phases of access to cessation support. Barriers were associated with both the abilities of smokers and the dimensions of cessation support, and the interaction between these barriers is both with each other and with the disadvantaged living conditions of lower SES smokers, and they were seen in each phase of transition. Overall, a comprehensive approach is needed to improve lower SES smokers' access to smoking cessation support and thereby, attenuating smoking-related health inequalities.
