Neighborhood social capital and incidence and mortality of prostate cancer : a Swedish cohort study

• Background: There is a growing interest in the contextual effect of neighborhood linking social capital on different health outcomes, including cancer. Aims: To examine associations between neighborhood linking social capital and incidence and mortality of prostate cancer. Method: This cohort study was based on national registers. Between 2002 and 2015, we included 1,196,563 men aged 50 years and above in the analyses. Multilevel logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CI) for the association between exposure and outcome, adjusting for potential confounding factors. Results: The total incidence of prostate cancer and mortality in patients with prostate cancer were 8.22 (per 100) and 1.80 (per 100), respectively, during the follow-up period. Individuals living in neighborhoods with low (OR 0.90; 95% CI 0.88–0.93) and intermediate (OR 0.94; 95% CI 0.92–0.96) linking social capital were less likely to be diagnosed with prostate cancer than those living in neighborhoods with high linking social capital. Opposite effects were observed for mortality; prostate cancer patients living in neighborhoods with low (OR 1.15; 95% CI 1.08–1.23) and intermediate (OR 1.09; 95% CI 1.03–1.14) linking social capital were more likely to die from prostate cancer than those in neighborhoods with high linking social capital. Conclusions: Lower neighborhood linking social capital was associated with lower incidence but higher mortality in patients with prostate cancer. These findings suggest that men living in neighborhoods with low linking social capital may need additional surveillance for prostate cancer.
