Risk Factor of The Incidence of Hyperemesis Gravidarum: A Population-based Case-control Study

Abstract

Hyperemesis Gravidarum is severe and excessive nausea and vomiting, starting at 4 and 6 weeks of gestation and peaking at 8-12 weeks of pregnancy, and usually subsiding by 20 weeks of gestation.  To recognize the risk factors for the incidence of hyperemesis gravidarum to detect early and reduce the consequences of hyperemesis gravidarum. This type of research is an analytical observational study with the research design of the Case Control method with a sample size of240.  This study uses secondary data, the instrument used is a data collection sheet with data sources coming from medical records. The results showed that risk factors have an association with the incidence of hyperemesis gravidarum, namely the age of pregnant women (p=0.014<0.05,OR0.38,).Parity (p=0.008,OR=2.14,).Gestational age(p=0.000,OR=49.63).Education(p=0.188,OR=0.500).Maternal occupation(p=0.002,OR=2.34).Maternal pregnancy spacing (p=0.004,OR=2.17),anemia in pregnancy(p=0.032<0.05,OR=0.422)and maternal status(p=0.004,OR=2.22). Almost all risk factors studied had a relationship Maternal age, parity,gestational age,maternal employment,pregnancy distance,anemia,and BMI status are risk factors for hyperemesis gravidarum.
