RESUMO
Background and Aims: The goal of this study was to demonstrate the effects of factors related with time to developing pre-eclampsia (PE) among pregnant women follow-up service at Arerti Primary Hospital. Methods: A survival analysis was employed on a pregnant women's follow-up service from September 2018 to June 2019 at the Arerti Primary Hospital. A closed-form sample size formula for estimating the effect of the time-to-event data was used. Both the descriptive method and Cox proportional hazards model were applied to compute the research survival data. Results: Using the Kaplan-Meier estimation technique, the univariable analysis shows that the survival time median is 7 months and 3 weeks. The graph of Kaplan-Meier estimate of total survival functions indicates a decreasing pattern of survivorship function. We used the Kaplan-Meier estimates to investigate the effects of observed differences among different categories of the factors, we applied the Log-rank test. The final survival model outcomes weight, marital status, age, history of PE, and multiplicity were related to a substantial hazard of evolving PE. Conclusion: On the basis of our final survival model results, we recommended that all pregnant women having such risk factors should see a health care professional and control their medical condition before and during pregnancy. Advising women about proper body weight in each follow-up period is supported. Finally, health experts should advise pregnant women about potential risk factors related to PE.
