Objective

Maternal smoking during pregnancy is associated with a reduction in birth size but the mechanism by which this occurs still remains unclear. The purpose of this study was to evaluate the effect of tobacco smoking on concentrations of pregnancy-associated plasma protein A (PAPP-A), insulin-like growth factor I (IGF-I), II (IGF-II) and binding proteins BP-3 and BP-4 in pregnant women and correlations between these parameters.

Methods

Sixty healthy pregnant women were divided into smoking and tobacco-abstinent group according to results of serum cotinine concentration. The current smokers were defined as those who had smoked five or more cigarettes per day during pregnancy.

Results

The mean serum concentrations of PAPP-A, IGF-I and IGF-II were significantly lower in smoking than in non-smoking pregnant women (p < 0.01). The level of PAPP-A correlated positively with the IGF-II concentration in both studied group (non-smoking: r = 0.54; p < 0.001; smoking: r = 0.40; p < 0.05). In tobacco-abstinent group negative correlation between IGF-II and IGFBP-4 concentrations was found (r = -0.35; p < 0.05).

Conclusion

Tobacco smoking during pregnancy decreases the pregnancy-associated plasma protein A and insulin growth factors I and II levels. The correlation between PAPP-A and IGF-II may suggest function of this protein as a protease and regulator in the IGF system."xsd:string
