Keywords:birth injury, risk factors, incidence
Objective: To determine the incidence and associated risk factors of birth injury among neonate who were born at Faculty of Medicine Vajira Hospital, Navamindradhiraj University from 2014-2016.
Study design: Case control study.
Methods: Data on 360 live birth newborns, including 120 newborns with birth injury (case) and 240 newborns without birth injury (controls), were studied for maternal, neonatal and delivery risk factors of birth injury.
Result: The incidence of birth injury were 57.22, 65.06 and 49.83 per 1,000 live birth newborns in 2014, 2015 and 2016, respectively. The three significant risk factors associated with birth injury were instrument delivery (OR 9.19, 95%CI 2.18-38.75, p-value 0.03) birth weight of 3,500 grams or grater (OR 3.48, 95%CI 1.71-7.05, p-value 0.001) and maternal age 35 years or older (odd ratio [OR] 2.30, 95% confidence interval [CI] 1.10-4.81, p-value 0.027).
Conclusion: The incidence of birth injury among neonates who were born at Faculty of Medicine Vajira Hospital was high. Factors associated with birth injury included instrument delivery, birth weight more than or equal 3,500 grams and elderly mothers.
