A scoping review of social relationships and prostate cancer screening

According to current US recommendations, the choice to undergo screening for prostate cancer should be an individual one, after considering with a clinician the balance of harms and benefits, and the values and preferences in the decision. Social relationships may influence such a decision. The purpose of this scoping review was to map the evidence on the association between social relationships and prostate cancer screening in the epidemiological literature and to highlight gaps in knowledge. We performed a systematic search of all relevant articles published up to February 1st 2021. We used variations in search terms related to prostate cancer screening, as well as indicators of social relationships. From the 908 records identified, 19 studies, published in 2007-2020, were included. The most common indicator of social relationships was marital status. Overall, married men or men with a partner had a higher screening uptake. Church attendance, based on studies conducted in the United states, was also associated with screening. We found little evidence linking screening with parenthood status or perceived social support. The overall evidence points to a potentially causal association between social relationships and men's decision to undergo prostate cancer screening. More research is needed on the underlying mechanisms and on the potential barriers and facilitators for screening.
