Secular trends and the pattern of growth in arctic populations

Examinations of growth patterns in Arctic populations suggest that Inuit/Inupiat (Eskimo) children display a unique pattern relative to European or continental U.S. children. This pattern--high weight for height--becomes established early in life and it has existed for as long as researchers have Inuit or Inupiat data. This paper will examine the growth pattern relative to the NCHS reference standard, using recent data from the Arctic and several indices combining height and weight. Of particular concern will be the persistence of this pattern in the face of secular trends in growth that have occurred over the past 50 years. Trends for height increase have been greater than those for weight but weight for height still remains well above the 50th percentile of the U.S. reference for these Arctic groups.
