N1  - This project was partially funded by the German National Cohort and the 1000BRAINSstudy of the Institute of Neuroscience and Medicine, Research Center Juelich, Germany.We thank the Heinz Nixdorf Foundation (Germany) for the generous support of theHeinz Nixdorf Study. We also thank the scientists and the study staff of the HeinzNixdorf Recall Study and 1000BRAINS. The study is also supported by the GermanMinistry of Education and Science.

AB  - Lifestyle contributes to inter-individual variability in brain aging, but previous studies focusedon the effects of single lifestyle variables. Here, we studied the combined and individualcontributions of four lifestyle variables - alcohol consumption, smoking, physical activity,and social integration - to brain structure and functional connectivity in a population-basedcohort of 549 older adults. A combined lifestyle risk score was associated with decreasedgyrification in left premotor and right prefrontal cortex, and higher functional connectivityto sensorimotor and prefrontal cortex. While structural differences were driven by alcoholconsumption, physical activity, and social integration, higher functional connectivity wasdriven  by  smoking.  Results  suggest  that  combining  differentially  contributing  lifestylevariables may be more than the sum of its parts. Associations generally were neither alteredby adjustment for genetic risk, nor by depressive symptomatology or education, underliningthe relevance of daily habits for brain health.
