RT Journal Article SR Electronic T1 Marital status and risk of cardiovascular diseases: a systematic review and meta-analysis JF Heart JO Heart FD BMJ Publishing Group Ltd and British Cardiovascular Society SP 1937 OP 1948 DO 10.1136/heartjnl-2018-313005 VO 104 IS 23 A1 Wong, Chun Wai A1 Kwok, Chun Shing A1 Narain, Aditya A1 Gulati, Martha A1 Mihalidou, Anastasia S A1 Wu, Pensee A1 Alasnag, Mirvat A1 Myint, Phyo Kyaw A1 Mamas, Mamas A YR 2018 UL http://heart.bmj.com/content/104/23/1937.abstract AB Background The influence of marital status on the incidence of cardiovascular disease (CVD) and prognosis after CVD is inconclusive. We systematically reviewed the literature to determine how marital status influences CVD and prognosis after CVD.Methods A search of MEDLINE and Embase in January 2018 without language restriction was performed to identify studies that evaluated the association between marital status and risk of CVD. Search terms related to both marital status and CVD were used and included studies had to be prospective in design. The outcomes of interest were CVD, coronary heart disease (CHD) or stroke incidence and mortality. We performed random effects meta-analysis stratified by the types of population by calculating odds ratios (OR) and 95% confidence intervals (95% CI).Results Our analysis included 34 studies with more than two million participants. Compared with married participants, being unmarried (never married, divorced or widowed) was associated with increased odds of CVD (OR 1.42; 95% CI 1.00 to 2.01), CHD (OR 1.16,95% CI 1.04 to 1.28), CHD death (OR 1.43,95% CI 1.28 to 1.60) and stroke death (OR 1.55,95% 1.16 to 2.08). Being divorced was associated with increased odds of CHD (P<0.001) for both men and women while widowers were more likely to develop a stroke (P<0.001). Single men and women with myocardial infarction had increased mortality (OR 1.42, 95% CI 1.14 to 1.76) compared with married participants.Conclusions Marital status appears to influence CVD and prognosis after CVD. These findings may suggest that marital status should be considered in the risk assessment for CVD and outcomes of CVD based on marital status merits further investigation.
