[Risk factors associated with intrauterine growth delay]

The term intrauterine growth delay (IGD) is used to refer a fetus with weight at birth lower than the 10th percentile for their gestational age.

to determine the prevalence and to identify risk factors associated with intrauterine growth delay in patients with normal fetal growth curves.

This study was made at General Hospital in Queretaro, Queretaro. There were included 70 obstetric patients with newborn with intrauterine growth delay (cases) and it was compared with 70 control patients with newborn without intrauterine growth delay.

There were studied 70 cases of a total of 192 registered during the period of this study. There was a prevalence of 2.5. Of all the newborn with intrauterine growth delay, 40 (47.2%) were female and 30 (42.8%) were male, relating with age, mothers below 20 and above 30 were not show significant differences The risk factors associated were mainly inadequate pregnant women weight (OR 4.84, CI 95%=1.56 to 16.1) and less than five medical appointments for medical control during prenatal period (OR 6.0, CI 95%=2048 to 14.81) , hypertensive disease during pregnancy (OR 5.09, CI 95%=1.4 to 20.21) and cervicovaginal infections (OR 5.09. CI 95%=1.52 to 21.56).

It is necessary to pay more attention to pregnant teenagers and also to general pregnant women to receive an adequate prenatal control in order to detect patients with risk of IGD and of this way to diminish morbidity and mortality in the newborn.
