Risk Factors for Birth Asphyxia In Kalasin Hospital

Abstract

Abstract

Background

Birth  asphyxia is an important cause of perinatal death. The causes of birth asphyxia are mostly due to the  processes during labor that may be prevented to reduce birth asphyxia and mortality of  the infant

Objective

To determine risk factors for birth asphyxia

Study design

Case control study

Setting

Obstetric and Gynecology department of Kalasin Hospital.

Subject

Cases were 159 newborns with 1-minute Apgar score of  7 or less, Controls were 318 newborns with 1-minute  Apgar score of more than 7,deliveried before and after each case.  All babies were deliveried in Kalasin Hospital between October 2001 and December 2002.

Method

Socio-economic factors, antepartum factors, intrapartum factors, fetal factors, were analysed with univariate  analysis and multiple logistic regression analysis.

Results

The incidence of birth asphyxia  was 36.1 per 1000 live births.  Factors significantly  associated with birth asphyxia included pregnancy induced hypertension (OR 26.81,  95% CI  6.44, 111.61),   breech presentation(OR 23.19,  95% CI  2.64, 203.54),  abnormal of electronic fetal monitoring (OR 8.3,  95% CI  3.08, 22.34),  cephalopelvic disproportion(OR 8.10,  95% CI  2.97, 22.20),  gestational age 28-32 weeks(OR 5.30,  95% CI  1.32, 21.22),  Cesarean section (OR 3.87,  95% CI  1.94, 7.68),   gestational age 33-36 weeks (OR 3.29,  95% CI  1.13, 9.52) , birth weight  less than 2500 grams (OR 3.17,  95% CI  1.25,8.06),   education £ 6^th grade(OR 3.09,  95% CI  1.60, 5.95).

Conclussion

Risk factors for birth asphyxia included socio-economic factors, antepartum factors, intrapartum factors, fetal factors. The hospital will use this information in developing interventions to reduce birth asphyxia

Key  word

Risk factor,  birth asphyxia
