Özet:

 

To investigate the influence of air  pollution on birth weight, information on  maternal and infant characteristics was  collected from 458 mothers of infants less  than one year of age born in 1995 and under  observation at a mother and child health  center in Ankara. In addition, the obstetrical  histories of 520 infants born in 1990 were  collected from the delivery room records of a  maternity hospital. Daily air pollution data  were obtained and mean monthly values  were used for statistical analysis. Among the  possible risk factors, sex, maternal age,  maternal employment, paternal employment  and parity were found to be influential  factors on low birth weight. In addition, first  trimester sulphur dioxide (SO 2 ) and  particulate matter (PM) levels were also  found to be factors affecting birth weight.  However, these effects were shown not to be  statistically significant by logistic regression  analysis. A comprasion of mean birth weights  according to maternal smoking and exposure  to passive smoking on the basis of the third  trimester SO 2 and PM levels revealed no  significant difference; however, the difference  in birthweight of non-smoking mothers was  higher than that of smoking mothers when  the third trimester SO 2 levels were above the  minimum effect level (100 g and 220 g,  respectively). These findings led us to  propose a synergistic effect of smoking and  air pollution. It was concluded that, air  pollution in Ankara is not on its own a major  risk factor for low birth weight.
