Background: Preeclampsia is the leading cause of the deaths of pregnant women in Indonesia (30.9%). The cause of preeclampsia until now is not known for sure. The purpose of this study was to determine the characteristics of preeclamptic pregnant women based on age, parity, body mass index and based on a history of hypertension, family history of hypertension, and level of education.Methods: The research method is observasional descriptive. The sampling technique is total sampling. The sample in this study were preeclamptic pregnant women in Dr. Mohammad Soewandhie Hospital in the period of 1 January up to 31 Desember 2017 amounting to 100 samples.Results: The results showed that 55% of preeclampsia pregnant women aged >35 years, 65% of primipaternity preeclampsia mothers, 63% obesity, 67% had no history of hypertension, 78% had no family history of hhypertension, and level of education does not affect the condition.Conclusions and Discussions: The highest risk factors for preeclampsia are age> 35 years, primipaternity and obesity. Therefore, it needs appropriate prevention methods to avoid the emergence of pregnancy problems and their complications include recognizing the signs and symptoms of preeclampsia, be aware of risk factors for the causes of preeclampsia, routine antenatal care, and adopting a healthy lifestyle.

Introduction: The World Health Organization (WHO) defines low birth weight (LBW) as a baby weighing less than 2500 grams. LBW is still a significant global public health issue because of its adverse effects on pregnant women's health. Nulliparity is also linked to low birth weight (LBW) and other factors that complicate pregnancy. Objective: This study aimed to find out if there was a link between maternal parity during pregnancy and the prevalence of LBW at the Gading Health Center in Surabaya. Method: This study is an analytical observational epidemiological study with a case-control approach. Data were analyzed using a comparative study hypothesis test between two variables in two independent sample groups of 40 mothers who have given birth to LBW babies and 40 mothers who have given birth to non-LBW babies. The MCH handbook contained a questionnaire and a health record form for pregnant women, which were used to collect data. The chi-square statistical test was used to analyze the data for this study. Results and discussion: The findings revealed a relationship between the number of parity (p = 0.005) and the occurrence of LBW, as determined by Odd's Ratio (0.214). The number of parities in primiparas mothers who gave birth to LBW and mothers who gave birth to non-LBW was more significant than the number of parities in multiparas. Conclusion: It is possible to conclude that there is a substantial relationship between the number of parities and the occurrence of LBW. To avoid the event of LBW, pregnant women should pay closer attention to the number of parity or the state of giving birth to live or dead children.
