Symptoms of pre-eclampsia can be identified by the presence of hypertension, proteinuria and edema during pregnancy until postpartum. Pre-eclampsia cannot be identified with certain risk factors, and cannot be prevented. Pre-eclampsia can be detected early using the pre-eclampsia screening method with sonography. The sonographic device used is referred to as DVAUt ultrasound (Uterine Artery Doppler Velocimetry Ultrasonography). This studying an analytic observational research with a cross sectional study design. The population was all pregnant women who examined at the Mulyorejo primary health center in 2013 until the first quarter of 2018. The sampling technique was consecutive sampling with inclusion and exclusion criteria. The number of samples obtained is 496 data. The study aimed to determine the sensitivity and specificity of the pre-eclampsia screening method using DVAUt ultrasound in detecting the tendency of pregnant women to experience pre-eclampsia. The data were analyzed of sensitivity and specificity and the Receiver Operating Characteristics (ROC) curve with p <0.001.

The purpose of this study is to identify the relationship between parents’ authoritarian parenting and the experience of teenage traffic accidents while riding a motorcycle. This research is a cross sectional study and uses two stage random sampling method. From the sampling process, as many as 222 students were obtained as respondents. The instrument used in this study consists of personal data and the Parental Authority Questionnaire (PAQ) to identify parenting style. Data analysis was carried out by logistic regression test with α= 5%. The data collection process was carried out during April-October 2017 in public and private high school in Surabaya. Logistic regression test results showed that there is no significant impact between parenting style and traffic accidents experienced by respondents (authoritarian p = 0.966; OR = 0.967, permissive p = 0.616; OR = 1.556). The conclusion of this study is that traffic accidents are not directly affected by parenting style, but it has role in forming individual characteristics, such as decision making and driving attitudes.","PeriodicalId":33106,"journal":{"name":"Jurnal Biometrika dan Kependudukan","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48476974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2015, the number of malnutrition cases was 6,745 (1.8 percent), which was lower than the targets of MDGs (15.0 percent) and the Strategic Plans of the Ministry of Health of the Republic of Indonesia (15.0 percent). However, according to National data (Dinkes, 2015), East Java was the second largest province with the highest cases of child malnutrition after the East Nusa Tenggara Province. The study aims to explain the direct and indirect causes of malnutrition among children under five years of age in the East Java Province in 2015. Using secondary data from the 2015 National Economic Social Survey in the East Java Province, the subjects of this research consisted of 38 districts and municipalities in the East Java Province. The results showed that the p values for each variable are: the length of breastfeeding in infants aged 0–23 months (X1) was 0.007, the percentage of completed immunization children under five years (X2) was 0.011, the percentage of the population consumption below 1400 kcal (X3) was 0.960, the proportion of households with adequate sanitation (X4) was 0.198, and the ratio of Enrolment Rates in Senior High Schools between female and male (X5) was 0.439. The conclusion of this study is that the independent variables were the time length of mothers in breastfeeding their infants aged 0–23 months and the percentage of children under five years of age who were fully immunized which had a negative correlation with malnutrition experinced by children under five years of age in the East Java Province in 2015.","PeriodicalId":33106,"journal":{"name":"Jurnal Biometrika dan Kependudukan","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44541886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
