Maternal age and parity associated with low birth weight infants

Abstract

Introduction: Low birth weight (LBW) infants indicate infant morbidity and infant mortality rates. In Indonesia, the infant mortality rate is still very high, with 32 deaths per 1 000 live births. The purpose of this study is to prove a relationship between maternal age and parity with LBW infants. Methods: This study used an observational crosssection study design. The sample selection used total sampling with a sample of 117 samples. The sample was collected from the medical record of Muhammadiyah Hospital of Surabaya for 12 months in 2018. Results: There were 74 mothers (63.2 %) of at-risk age, and 110 mothers (94 %) had risk parity. There was a significant effect of maternal age on infant birth weight (p=0.000). Mothers with a risk age increased the tendency to give birth to LBW infants by 52.720 times. There was a significant effect of maternal parity on infant birth weight (p=0.014). Mothers with parity at risk increased the likelihood of giving birth to infants with LBW by 36.856 times. The formula predicts the occurrence of LBW is equal with-11.126+3.965*Age+3.607*Parity. Conclusion: Maternal age and parity were associated with LBW infants.
