Determinants of Mortality Among New England Cotton Mill Workers During the Progressive Era
研究1905-1912年新英格兰棉纺厂工人的死亡率，发现工厂工作提高了年龄调整后的死亡率，且随工龄增加而上升；不同群体因职业选择受限程度不同，死亡率存在差异，其中已婚女工死亡率最高。
Multiple regression analysis reveals that work in New England cotton textile mills during 1905–1912 raised age-adjusted mortality rates over those of non-mill- workers, and that worker mortality increased with years of mill experience. Mortality varied among groups because of differential self selection. Central age group native males with broad occupational choices had lower mortality rates than control groups. Young males, women, and the foreign born had restricted occupational choices. Hence they were less self selected and experienced higher mortality. Death rates were highest among married women workers who bore children. The combination of homework and millwork worsened their health and raised their mortality rates.
