R elationship Between Parity Interval And IncidenceOf Preeclampsia In The Reproductive AgeBACGRPreeclampsia is the most common complication encountered in the assessment and is one of the biggest contributors to the Maternal Mortality Rate (MMR). According to the Indonesian Obstetrics and Gynecology Association, the prevalence of preeclampsia in Indonesia is 5.3%. From the many risk factors for preeclampsia, one risk factor for multiparous women is the parity interval. Parity interval with the incidence of preeclampsia. The study used an observational analytic study involving cross sectional which included women of reproductive age (20 - 35 years) who had obtained the number 1 time, between 2015 - 2017 at Delima Asih Hospital, Karawang. Sampling was done by simple random sampling from medical records of multiparous women diagnosed with preeclampsia during their pregnancy. The variables that are issued are the distance of pregnancy (parity interval) and preeclampsia. Data analysis using chi-square test and processed with SPSS V20.0 for windows program with the significance level used 0.05. Of the 65 respondents, most were respondents with an age range of 20-30 years, namely 34 respondents (52.3%), distant parity intervals (> 4 years) with 30 respondents (46.2%), diagnosed with severe preeclampsia (PEB) As many as 49 respondents (75.4%), without risk factors as many as 64 respondents (98.5%), secondary level education with a total of 31 respondents (47.7%), and antenatal care as many as 65 respondents (100%). Whereas respondents with distant parity intervals (> 4 years), there were 3 respondents (10%) with a diagnosis of preeclampsia (PE) and 27 respondents (90%) with a diagnosis of severe preeclampsia (PEB). There was a correlation between the parity interval and preeclampsia in reproductive age (P = 0.037). This study shows an association between parity intervals and the incidence of preeclampsia in reproductive age.OUNDMaternal hypertension (preeclampsia) is the most commmon complication in pregnancy and is one of the largest contributor to maternal mortality rate (MMR). According to POGI (Perkumpulan Obstetri dan Ginekologi Indonesia), the prevalence of preeclampsia in Indonesia is 5,3%. Of the many risk factors for preeclampsia, one of the risk factor for multiparous women is the interbirth interval. This study was conducted to determine the relationship of interbirth interval and preeclampsia.METHOD A cross-sectional observational study was conducted, involving women in their reproductive age (20 – 30 years old) that has given birth at least once, from the year 2015 - 2017 at Delima Asih Sisma Medika Hospital in Karawang. Samples were collected using simple random sampling from medical records of multiparous women that were diagnosed with preeclampsia in their pregnancy. The variables studied were interbirth interval and preeclampsia. The datas were analyzed using chi-square test and processed with SPSS V20.0 software for windows with a significance level of 0.05. RESULTSFrom 65 respondents, most of them were inthe age range of 20-30 years old with 34 respondents (52.3%), longinterbirth interval (> 4 years) with 30 respondents (46.2%), diagnosed with severe preeclampsia (PEB) as many as 49 respondents (75.4%), without risk factors as many as 64 respondents (98.5%), middle range education level with 31 respondents (47.7%), and have done antenatal care with 65 respondents (100%). As for respondents with longinterbirth interval (> 4 years), there were 3 respondents (10%) diagnosed with preeclampsia (PE) and 27 respondents (90%) with severe preeclampsia diagnosis (PEB). There is a significant relationship between interbirth interval and preeclampsia at reproductive age (P = 0.037). CONCLUSION This study showed that there is a significant relationship between imterbirth intervals (IBI) and preeclampsia
