OBJECTIVES. Reduced options for fertility control over the past decade have increased the rates of unwanted pregnancy. We evaluated whether a woman's negative attitude toward her pregnancy increased the risk of perinatal mortality, in a large, prospective cohort study. METHODS. The association between attitude toward the pregnancy and perinatal mortality was evaluated in a longitudinal cohort study of 8823 married, pregnant patients enrolled from 1959 to 1966 in the Child Health and Development Studies. RESULTS. Women who reported during the first trimester of prenatal care that the pregnancy was unwanted were more than two times more likely to deliver infants who died within the first 28 days of life than were women reporting accepted pregnancies. A positive attitude toward pregnancy was not associated with fetal death or post-neonatal death. CONCLUSIONS. These data, collected when induced abortions were illegal, may have important implications for the 1990s. If maternal attitude toward the pregnancy is associated with neonatal mortality and abortion laws change such that access is restricted, infant mortality may increase because a greater proportion of births will be unwanted.
Abstrak. Analisis survival merupakan metode statistika yang digunakan untuk menganalisis data dimana peubah yang diperhatikan adalah waktu sampai terjadinya suatu event. Waktu dapat dinyatakan dalam tahun, bulan, minggu, atau hari dari awal mula dilakukan pengamatan pada seorang individu sampai suatu peristiwa terjadi pada individu. Salah satu tujuan analisis survival adalah untuk mengetahui hubungan antara waktu kejadian dan peubah bebas yang terukur pada saat dilakukan penelitian. Salah satu pendekatan metode regersi yang bisa digunakan adalah regresi Cox Proportional Hazard. Data yang digunakan dalam penelitian ini adalah data pasien penderita demam tifoid di RSUD Haji Makassar. Data demam tifoid memiliki karakteristik yang memungkinkan untuk dilakukan analisis dengan menggunakan regresi Cox Proportional Hazard. Adapun analisisnya menggunakan pendugaan parameter Bayesian, diperoleh faktor yang signifikan berpengaruh terhadap laju kesembuhan pasien adalah nyeri ulu hati. Nilai hazard ratio peubah nyeri ulu hati sebesar 0,63. Nilai tersebut <1 sehingga dapat dikatakan bahwa pasien yang mengalami nyeri ulu hati memiliki laju kesembuhan 0,63 kali dibandingkan yang tidak mengalami nyeri ulu hati.Kata Kunci: Survival Analysis, Regression Cox Proportional Hazard, Thyfoid Fever
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
