It is not clear why mortality rates during the epidemic were so high. One possibility is that the affected human populations were particularly stressed in the 14<jats:sup>th<\/jats:sup>century, perhaps as a result of repeated famines in areas such as England. This project examines survival and mortality in two pre\u2010Black Death time periods, 11\u201312<jats:sup>th<\/jats:sup>centuries vs 13<jats:sup>th<\/jats:sup>century CE, to determine if demographic conditions were deteriorating before the epidemic occurred.<\/jats:p><\/jats:sec><jats:sec><jats:title>MATERIALS AND METHODS<\/jats:title><jats:p>This study is done using a sample of individuals from several London cemeteries that have been dated, in whole or in part, either to the 11\u201312<jats:sup>th<\/jats:sup>centuries (<jats:italic>n<\/jats:italic>\u2009=\u2009339) or 13<jats:sup>th<\/jats:sup>century (<jats:italic>n<\/jats:italic>\u2009=\u2009258). Temporal trends in survivorship and mortality are assessed via Kaplan\u2013Meier survival analysis and by modeling time period as a covariate affecting the Gompertz hazard of adult mortality.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The age\u2010at\u2010death distributions from the two pre\u2010Black Death time periods are significantly different, with fewer older adults in 13<jats:sup>th<\/jats:sup>century. The results of Kaplan\u2013Meier survival analysis indicate reductions in survival before the Black Death, with significantly lower survival in the 13<jats:sup>th<\/jats:sup>century (Mantel Cox<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Last, hazard analysis reveals increases in mortality rates before the Black Death.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>Together, these results suggest that health in general was declining in the 13<jats:sup>th<\/jats:sup>century, and this might have led to high mortality during the Black Death. This highlights the importance of considering human context to understand disease in past and living human populations.
