To overcome the endogeneity of heavy smoking behaviour, we employed a novel approach by exploiting the genetic predisposition to heavy smoking, as measured with a polygenic risk score (PGS), in a Mendelian Randomisation approach. Methods: 8164 participants (mean age 68.86 years) from the English Longitudinal Study of Ageing had complete data on smoking behaviour, employment and a heavy smoking PGS. Heavy smoking was indexed as smoking at least 20 cigarettes a day. A time-to-event Mendelian Randomization (MR) analysis, using a complementary log–log (cloglog) link function, was employed to model the retirement risk. Results: Our results show that being a heavy smoker significantly increases the risk of retirement (β = 1.324, standard error = 0.622, p < 0.05). Results were robust to a battery of checks and a placebo analysis considering the never-smokers. Conclusions: Overall, our findings support a causal pathway from heavy smoking to earlier retirement.}, organization = {National Institute on Aging (Grant: RO1AG7644)}, organization = {consortium of UK government departments coordinated by the Economic and Social Research Council}, organization = {Tomas y Valiente Fellowship funded by the Madrid Institute for Advanced Study (MIAS), Universidad Autonoma de Madrid (UAM), Spain}, organization = {PID2022- 137819NB-I00 funded by the Spanish government}, publisher = {Elsevier}, keywords = {Smoking}, keywords = {Retirement risk}, keywords = {Polygenic Risk Scores}, title = {The effect of heavy smoking on retirement risk: A mendelian randomisation analysis}, doi = {10.1016/j.addbeh.2024.108078}, author = {Gaggero, Alessio and Ajnakina, Olesya and Zucchelli, Eugenio and Hackett, Ruth A.}, }
