BackgroundIntrauterine growth restriction (IUGR) is a disorder in which the fetus fails to reach its genetic development potential and is considered to be present when the weight at birth is less than the 10th percentile; as a result, it is at risk of increased postnatal morbidity and mortality. Every year, approximately 24% of newborns worldwide are determined to have IUGR. The objective of the present study was to identify various sociodemographic, medical, and obstetric risk factors associated with IUGR.MethodologyA case-control study was conducted from January 2020 to December 2022. Fifty-four cases and 54 controls were included in the study. Postnatal women with neonates having birth weight below the 10th percentile for gestational age (GA) were recruited as cases in the study. Control cases were postnatal women with neonatal birth weight appropriate for (GA). Detailed history with respect to socio-demographic, medical, and obstetric parameters was noted and compared.ResultsAmong the sociodemographic factors, only socioeconomic status showed significant statistical differences with the age group of 21 to 25 years showing maximum (51.9%) IUGR cases. Among the maternal risk factors, anemia (29.6%) and hypertensive disorders of pregnancy (22.2%) were marked as significant risk factors for IUGR. There was no significant difference in the distribution of past medical and obstetric histories between the two research groups.ConclusionDue to the poor living conditions, low literacy rates, and general lack of knowledge, low socioeconomic level increases the risk of IUGR. This leads to nutritional deficiencies and insufficient growth environment which results in anemia and hypertensive disorders of pregnancy which are potent risk factors for IUGR. IUGR may be caused by maternal risk factors as well as past medical and obstetric conditions. However, for the risk factor of IUGR, the birth weight at the time of delivery could be taken into consideration as well.
