Iroquoian Infant Mortality and Juvenile Growth 1250 to 1700 AD
This thesis investigates changes in Iroquoian infant mortality and juvenile growth between 1250 and 1700 AD in the Lower Great Lakes region of North America. The objectives of this thesis are to investigate the tempo and quality of growth of Iroquoian infants and juveniles; to investigate the relati...

The objectives of this thesis are to investigate the tempo and quality of growth of Iroquoian infants and juveniles; to investigate the relationship between apparent neonatal and postneonatal mortality and predicted mortality ratios based on equal probability of mortality risk in the first year of life (1:11); and to investigate whether or not the ratio of neonatal to postneonatal mortality changed as a result of cultural change associated with the arrival of Europeans at around 1600 AD. These were investigated using a sample of infant and juvenile remains from twenty-one sites in upper New York state and Ontario. Tempo and quality of growth were examined by comparing femoral length at different ages to the Iroquoian adult femur length endpoint and to the growth patterns established in the Denver Growth Study and in other aboriginal North American archaeological samples. Above average infant growth is attributed to biocultural factors and infant mortality is largely caused by acute conditions. Below average juvenile growth, especially between two and seven years of age, is attributed to nutritional imbalances and overcrowding, poor sanitation, and infectious disease prevalence. Juveniles were likely chronically ill, resulting in poor attainment of stature, and this may have contributed to their deaths early in life. Apparent infant mortality was found to differ from predicted mortality, and this difference was attributed to cultural and environmental mortality biases that make interpretation difficult. Change in infant mortality ratios as a result of cultural change associated with European contact is evident in the Iroquoian context: the lack of neonatal remains in postcontact ossuaries is consistent with the ethnohistoric record, but the high proportion of neonates in precontact ossuaries suggests that observations made by ethnohistoric observers may not be applicable to our understanding of precontact burial patterns. The change in the ratio of neonatal to postneonatal remains in the pre- and postcontact periods is interpreted as evidence of changes in burial patterns rather than change in mortality risk.

This thesis investigates changes in Iroquoian infant mortality and juvenile growth between 1250 and 1700 AD in the Lower Great Lakes region of North America. The objectives of this thesis are to investigate the tempo and quality of growth of Iroquoian infants and juveniles; to investigate the relationship between apparent neonatal and postneonatal mortality and predicted mortality ratios based on equal probability of mortality risk in the first year of life (1:11); and to investigate whether or not the ratio of neonatal to postneonatal mortality changed as a result of cultural change associated with the arrival of Europeans at around 1600 AD. These were investigated using a sample of infant and juvenile remains from twenty-one sites in upper New York state and Ontario. Tempo and quality of growth were examined by comparing femoral length at different ages to the Iroquoian adult femur length endpoint and to the growth patterns established in the Denver Growth Study and in other aboriginal North American archaeological samples. Above average infant growth is attributed to biocultural factors and infant mortality is largely caused by acute conditions. Below average juvenile growth, especially between two and seven years of age, is attributed to nutritional imbalances and overcrowding, poor sanitation, and infectious disease prevalence. Juveniles were likely chronically ill, resulting in poor attainment of stature, and this may have contributed to their deaths early in life. Apparent infant mortality was found to differ from predicted mortality, and this difference was attributed to cultural and environmental mortality biases that make interpretation difficult. Change in infant mortality ratios as a result of cultural change associated with European contact is evident in the Iroquoian context: the lack of neonatal remains in postcontact ossuaries is consistent with the ethnohistoric record, but the high proportion of neonates in precontact ossuaries suggests that observations made by ethnohistoric observers may not be applicable to our understanding of precontact burial patterns.
