Risk factors of cerebral palsy in the perinatal period

Abstract

Background Cerebral palsy is an irreversible yet preventable
condition, thus it is necessary to know the risk factors of the
disease. The potential risk factors that are found in the perinatal
and neonatal period i.e. asphyxia, sepsis, very low birth weight,
premature birth, and neonatal seizure. No available data for the
risk factors of cerebral palsy in Indonesia.
Objective To identify the perinatal risk factors in cerebral palsy.
Methods We performed an age and sex-matched nested case-
control study. The case group was children with cerebral palsy
who were born at Sardjito Hospital during 1997-2005. The control
group was selected from the same population as the case group.
Risk factors during the perinatal period consisted of asphyxia,
sepsis, very low birth weight, premature birth and neonatal seizure.
Logistic regression was used to determine the association between
risk factors and cerebral palsy.
Results Univariate analysis showed that the following factors were
risk factors for cerebral palsy, i.e., asphyxia (OR 5.6, 95%CI 2.48;
12.53); premature birth (OR 4.5; 95%CI 1.55; 13.13); and neona-
tal seizure (OR 7.5, 95%CI 3.13; 18.03). On multivariate analysis
risk factors associated with cerebral palsy were asphyxia (aOR
6.3, 95%CI 2.42; 16.66) and neonatal seizure (aOR 10.9,95%CI
4.03; 29.97).
Conclusion Asphyxia and neonatal seizure are significant risk
factors of cerebral palsy in perinatal period
