INTRODUCTION Differences in smoking prevalence across socioeconomic groups are a major driver of health inequalities. Although smoking prevalence continues to decline across most developed countries, socioeconomic inequalities in smoking still persist. While Ireland is among a small number of countries with a tobacco-endgame goal set to achieve a smoking prevalence of 5% by 2025, the challenge this presents by socioeconomic status is uncharted.
AIMS AND METHODS We analyzed how differences in smoking status across various socioeconomic groups have changed over time in the adult population in Ireland. We used cross-sectional smoking data from the national population-based Healthy Ireland Survey for 2015-2022 (n = 52 494). Educational attainment and area-based deprivation were used as socioeconomic indicators. Socioeconomic differences and changes in inequality over time were identified using the relative index of inequality (RII). Multinomial logistic regression was used to analyze the association between socioeconomic status and daily smoking, occasional smoking, former smoking, and never smoking with adjustment for sex, age, and survey year.
RESULTS We observed the highest daily smoking rates among the least educated (OR = 11.62; 95% CI = 9.91, 13.63) and individuals living in the most deprived areas (OR = 4.23; 95% CI = 3.55, 5.04). Additionally, we identified significant relative smoking inequalities over the observation period continued to increase, among the least educated (RII = 2.86, 95%CI = 2.63, 3.09) and individuals living in the most deprived areas (RII = 2.64, 95% CI = 2.36, 2.93).
CONCLUSIONS Despite generally reducing smoking prevalence, socioeconomic inequalities continue to widen among the smoking population in Ireland.
IMPLICATIONS As the tobacco endgame deadline of 2025 is fast approaching, this study highlights the urgent need to consider potential effects across the lowest socioeconomic status groups when implementing equity-oriented tobacco control policies.
