We analyzed whether genetic liability to CHD may affect these associations. Methods: Marital status, a polygenic score of CHD (PGS-CHD), and other risk factors for CHD were measured from 35,444 participants (53% female) in Finnish population-based surveys conducted between 1992 and 2012. During the register-based follow-up until 2020, there were 2439 fatal and non-fatal incident CHD cases. The data were analyzed using linear and Cox regression models. Results: Divorced and cohabiting men and women had a higher genetic risk of CHD than married individuals, but the difference was very small (0.023–0.058 standard deviation of PGS-CHD, p-values 0.011–0.429). Both marital status and PGS-CHD were associated with CHD incidence, but the associations were largely independent. Adjusting for behavioral and metabolic risk factors for CHD explained part of these associations (11–20%). No interaction was found between marital status and PGS-CHD for CHD incidence. Conclusions: We showed minor differences between the marital status categories in PGS-CHD and demonstrated that marital status and genetic liability predicted CHD incidence largely independently. This emphasizes the need to measure multiple risk factors when predicting CHD risk. date: 2022-09-07 date_type: published publisher: SAGE PUBLICATIONS LTD official_url: https://doi.org/10.1177/14034948221119634 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1977816 doi: 10.1177/14034948221119634 medium: Print-Electronic lyricists_name: Morris, Tim lyricists_id: TMORR75 actors_name: Morris, Tim actors_id: TMORR75 actors_role: owner funding_acknowledgements: 345219 [Academy of Finland]; 308247 [Academy of Finland]; 101019329 [European Research Council under the European Union]; MC_UU_00011/1 [UK Medical Research Council] full_text_status: public publication: Scandinavian Journal of Public Health pages: 4 event_location: Sweden issn: 1403-4948 citation: Silventoinen, Karri; Lahtinen, Hannu; Korhonen, Kaarina; Smith, George Davey; Ripatti, Samuli; Morris, Tim; Martikainen, Pekka; (2022) Marital status and genetic liability independently predict coronary heart disease incidence.
