The Occurrence and Age Distribution of Harris Lines in Turkey

Abstract

Harris lines are widely accepted as indicators of physiological stress and provide valuable data for determining the extent and nature of the physiological stress factors acting on a human community. Traditionally, Harris lines are studied in skeletal populations. In the study reported here, data were collected on living children to eventually clarify if stress is basically chronic or acute in nature, if it has a greater impact on children or adults, and if it is correlated with increased rates of mortality. The existence of Harris lines was determined in a sample of 400 children, 210 males and 190 females, randomly selected from those under examination in the radiology services of hospitals. Radiological analysis was used to analyze Harris lines. The age of Harris line formation and variations in the number of lines with age were established to determine at which age the densest line population was present. For this sample, the formation of Harris lines is around 2–3 years of age, in agreement with published literature. It should be taken into consideration that Harris lines are the end result of multiple factors, rather than a single stress factor, and are influenced by an individual’s immune system and resistance to stress.
