This study examines the relative effects of population density and area-level SES on all-cause mortality in Denmark. A shared frailty model was fitted with 2.7 million persons aged 30-81 years in 2,121 parishes. Residence in areas with high population density increased all-cause mortality for all age groups. For older age groups, residence in areas with higher proportions of unemployed persons had an additional effect. Area-level factors explained considerably more variation in mortality among the elderly than among younger generations. Overall this study suggests that structural prevention efforts in neighborhoods could help reduce mortality when mediating processes between area-level socioeconomic status, population density and mortality are found.
本研究考察了人口密度和地区社会经济地位对丹麦全因死亡率的相对影响。使用 270 万人的数据（年龄在 30-81 岁之间，分布在 2121 个教区）拟合了一个共享脆弱性模型。居住在人口密度高的地区会增加所有年龄段的全因死亡率。对于年龄较大的人群，居住在失业率较高的地区会产生额外的影响。与年轻一代相比，地区层面的因素可以更好地解释老年人之间的死亡率差异。总的来说，本研究表明，当发现地区社会经济地位、人口密度和死亡率之间的中介过程时，邻里结构预防措施可能有助于降低死亡率。
