Abstract: Objective: The association of cardiovascular (CV) risk with social isolation and loneliness remains poorly studied. The purpose of this cross-sectional study was to investigate the associations between social isolation and loneliness with estimated 10-year atherosclerotic cardiovascular disease (ASCVD) risk. Methods: Among 302,553 volunteers of the UK Biobank population, social isolation and loneliness were assessed with a questionnaire. Associations between social isolation and loneliness with ASCVD risk were estimated using multiple gender regressions. Results: Men presented a higher estimated 10-year ASCVD risk (8.63% vs. 2.65%, p < 0.001) and higher proportions of social isolation (9.13% vs. 8.45%, p < 0.001) and loneliness (6.16% vs. 5.57%, p < 0.001) than women. In all covariate-adjusted models, social isolation was associated with an increased ASCVD risk in men ( B = 0.21 (0.16; 0.26), p < 0.001) and women ( B = 0.12 (0.10; 0.14), p < 0.001). Loneliness was associated with an increased ASCVD risk in men ( B = 0.08 (0.03; 0.14), p = 0.001) but not in women ( p = 0.217). A significant interaction was observed between social isolation and loneliness with ASCVD risk in men ( p = 0.009) and women ( p = 0.016). After adjustment for all covariates, both social isolation and loneliness were significantly associated with ASCVD risk in men ( B = 0.44 (0.28; 0.61), p < 0.001) and women ( B = 0.20 (0.12; 0.29), p < 0.001). Conclusion: Social isolation was associated with a higher estimated 10-year ASCVD risk in both genders but only loneliness among men. Social isolation and loneliness can be considered potential added risk factors for CV risk. Health policies should address these notions in prevention campaigns, in addition to traditional risk factors.
