The Acceleration of Birth Weight and Birth Length of Hypotrophic and Hypertrophic Newborns From Tuzla Canton from 1976 to 2007

Amela Begić, Jasminka Halilović


The acceleration or secular changes are long-term systematic changes across a broad spectrum of anthropological variables in successive generations of the population living in the same territory. The phenomenon can be seen in the size of newborns in the period of childhood and early youth, but also at the population level. The research used the data from the book of protocols, from the Departament of Gynecology and Obstetrics, University Clinical Centre in Tuzla. The sample taken from 19312 newborns (10037 boys, or 51.97%, and, 9275 girls, or 48.03%) was composed of four sub-samples of newborns of both sexes, as follows: sub-samples of infants between 01 January and 31 December of the following calendar years: 1976, 1987, 1997 and 2007. The aim of this research paper is to determine the acceleration of birth weight and birth length of hypotrophic (birth weight less than 2500g) and hypertrophic infants (birth weight greater than 4000g) of both sexes in Tuzla Canton, in four time points. On the basis of mathematical-statistical methods, the acceleration of the birth weight of the total sample of hypotrophic neonates with negative values, ranged from - 21.39 g / decade and -2.48 g / dec in hypertrophic newborns. The acceleration of birth length of hypotrophic infants in the total sample was 0.14 cm / decade, and in hypertrophic 0.62 cm / decade. Conclusion: it is presumed that this secular change was caused by massive and violent population migrations during the 1992-1996 war in Bosnia and Herzegovina, when there was a change in the genetic composition of the local population.
