关于社会经济因素对1918年流感大流行期间流感相关死亡的作用，文献中缺乏共识。虽然一些学者发现社会因素很重要，但其他人则不然。在这项研究中，我们分析了1918年大流行期间瑞典社会阶层超额死亡率的差异。我们通过结合死亡记录和职业普查数据，分析了30-59岁整个人口的个人水平死亡率。社会阶层是由一个基于职业的阶级计划来衡量的。大流行期间的超额死亡率是以死亡人数相对于前一年同月的死亡人数来衡量的。使用互补双对数模型对死亡人数的社会阶层差异进行建模，该模型针对家庭、住宅（城市/农村）和县一级的潜在混杂因素进行了调整。我们发现，在超额死亡率显着的类差异，但没有完美的类梯度。男性的阶级差异比女性大一些。
Consensus is lacking in the literature about the role of socioeconomic factors on influenza-associated deaths during the 1918 pandemic. Although some scholars have found that social factors were important, others have not. In this study, we analyzed differences in excess mortality by social class in Sweden during the 1918 pandemic. We analyzed individual-level mortality of the entire population aged 30-59 years by combining information from death records with census data on occupation. Social class was measured by an occupation-based class scheme. Excess mortality during the pandemic was measured as the number of deaths relative to the number occurring in the same month the year before. Social class differences in numbers of deaths were modeled using a complementary log-log model that was adjusted for potential confounding at the family, the residential (urban/rural), and the county levels. We found notable class differences in excess mortality but no perfect class gradient. Class differences were somewhat larger for men than for women.
