| Abstract: | Early cancer detection is fundamental to the promotion of better health in the community, but disparities remain in the likelihood of cancer being detected at an early stage, some of which relate to socio‐demographic factors such as marital status. The aim of this study was to conduct a systematic review of research on the association between marital status and stage at diagnosis of different types of cancer. A comprehensive systematic literature search was run in the Medline and Scopus databases (from January 1990 to June 2014), identifying 245 and 208 articles on PubMed and Scopus respectively. Of these 453 studies, 18 were judged eligible for this systematic review. A quality assessment was performed on the studies using the 22 items in the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) checklist. This review confirmed the important influence of being married on the earlier detection of cancer. None of the studies considered identified more cases of cancer in a later stage among married patients, and the majority of them reported a statically significant association between marital status and stage at diagnosis, with a positive effect of marriage on the likelihood of cancer being diagnosed at an early stage, for various types of malignancy. In particular, our meta‐analysis showed that the unmarried have higher odds of having a later stage of breast cancer (OR = 1.287 95% CI: 1.025–1.617) or melanoma (OR = 1.350 95% CI: 1.161–1.570) at diagnosis. Specific interventions should be developed for the unmarried population to improve their chances of any neoplasms being diagnosed at an early stage, thereby reducing health disparities in the population at large. |
