Monroe DC, McDowell CP, Kenny RA, et al. - In a nationally representative sample of Irish older adults, researchers sought to quantify relationships between smoking and smoking cessation on prevalent and incident generalised anxiety disorder (GAD) and major depression (MDD). Candidates (n = 6,201) were community-dwelling adults aged ≥ 50 years resident in Ireland. Smoking status and self-reported doctor diagnosis of anxiety or depression prior to baseline were evaluated at baseline. Data reported that prevalence and incidence of depression was 11.1% (n = 686) and 6.4% (n = 342), respectively. Former smokers had higher chances of prevalent GAD compared with non-smokers. Current smokers had no increased risk of incident MDD or GAD compared with non-smokers. The findings may have important implications for tobacco abuse interventions, which have a lower success rate among those suffering from anxiety and depression.
