Abstrak Latar Belakang: Persalinan prematur merupakan salah satu tantangan penting yang menghambat penurunan angka kematian neonatal sejalan dengan target Tujuan Pembangunan Berkelanjutan (SDGs) 2030. Pada tahun 2015, sekitar 1 juta bayi di seluruh dunia meninggal karena komplikasi persalinan prematur. Indonesia sendiri menempati posisi ke-9 di dunia dengan angka kejadian persalinan prematur sebesar 15,5 bayi per 100 kelahiran hidup. Morbiditas bayi prematur berpengaruh secara fisik hingga tahap perkembangan selanjutnya dan menjadi beban psikologis dan finansial bagi bayi, ibu dan keluarga. Salah satu faktor yang diduga berhubungan dengan persalinan prematur adalah karakteristik sosial demografi yang meliputi usia ibu, latar belakang pendidikan ibu, dan status pekerjaan ibu. Penelitian ini bertujuan untuk mengetahui hubungan antara karakteristik sosio-demografis dengan kejadian persalinan prematur di RSUD Cilegon. Metode: Desain penelitian adalah studi kasus-kontrol dengan menggunakan data sekunder dari rekam medis RSUD Cilegon periode Januari 2015 sampai Juni 2016. Sampel kasus dipilih secara total sampling, sedangkan sampel kontrol dipilih secara simple random sampling dan mencocokkan jumlah sampel kontrol berdasarkan jumlah kasus per sampel per bulan. Metode analisis yang digunakan adalah analisis bivariat dengan uji chi-square, menilai odds ratio dan interval kepercayaan. Hasil: Analisis bivariat menghasilkan OR 1,44 (95% CI: 0,68-3,03) dengan p-value 0,34 pada ibu usia > 35 tahun, OR 1,76 (95% CI: 0,68-4,55) dengan p-value 0,24 pada ibu hamil wanita berlatar belakang pendidikan SD/sederajat, dan OR sebesar 0,72 (95% CI: 0,30 -1,72) dengan p-value 0,42 pada wanita hamil yang bekerja. Kesimpulan: Karakteristik sosiodemografi tidak berhubungan dengan persalinan prematur.

In 2015, around 1 million babies worldwide died due to complications of premature labor. Indonesia itself occupies the 9th position in the world with the incidence of premature birth of 15.5 babies per 100 live births. Morbidity of premature babies affects physically until the next stage of development and becomes a psychological and financial burden for the baby, mother and family. One of factors thought to be associated with prematur birth is socio-demographic characteristics which includes maternal age, educational background of mother, and working status of mother. The aim of this study was to determine the relationship between socio-demographic characteristics and premature delivery at RSUD Cilegon. Methods: The research design was a case-control study using secondary data from the medical records of RSUD Cilegon for the period January 2015 to June 2016. The case sample was selected by total sampling, while the control sample was selected by simple random sampling and matched the number of control samples based on the number of cases per sample by month. The analytical method was bivariate analysis with the chi-square test, assessing odds ratios and confidence intervals. Result: The bivariate analysis yielded OR of 1.44 (95% CI: 0.68-3.03) with p-value 0.34 in maternal age > 35 years old,  OR of 1.76 (95% CI: 0.68 -4.55) with p-value 0.24 in pregnant women who was elementary school/equivalent for educational background, and OR of 0.72 (95% CI: 0.30 -1.72) with p-value 0.42 in pregnant women who was working. Conclusion: Sociodemographic characteristics were not associated with premature delivery. Keywords: Premature delivery, Socio-demographic characteristics, Case-control studies, Cilegon

Introduction: Adolescent reproductive health education aims to increase knowledge and attitudes about reproductive health. Therefore, an easy, inexpensive, and standardized method of education is needed in the delivery of reproductive health material to young adolescents, one of them is audiovisual media animationMethod: The research was conducted using a pre-experimental research design pretest-posttest one group design within 31 days. This study used a total sample of 180 subjects, furthermore, the data were analyzed using Structural Equation Modeling (SEM).Result: Education with reproductive health animated videos increased knowledge about reproductive health immediately after education was given (P = 0.002), but after 31 days, it did not affect (P = 0.171). Education with animated videos did not affect the subjects’ attitude immediately after education was carried out (P = 0.802) but had an effect after 31 days from the start of education (P = 0.031). After analyzing the correlation including other confounding variables (R square), it was found that the effect of education with animated videos towards the increasing knowledge of reproductive health was 14.9%, and 8.4% towards changes in subject attitudes.Discussion: Health education with video animation increases knowledge, but the phenomenon of attitudes such as dating still occurs even the subjects’ knowledge have increased.Conclusion: Reproductive health education using animated videos increases knowledge but does not change attitudes in reproductive health
