Determinants of Immediate Postpartum Long Acting Reversible Contraceptive Utilization among Women Who Gave Birth in Public Health Facilities in Northwest Ethiopia: Unmatched Case-control Study Design

A facility-based unmatched case-control study was carried out, involving 342 postpartum women (comprising 108 cases and 216 controls) who delivered in public health facilities in northwest Ethiopia. Data collection involved employing a structured interviewer-administered questionnaire, and binary logistic regression analysis was conducted. The statistically significant association between independent factors and the outcome variable was assessed using the adjusted odds ratio with a 95% confidence interval, considering a p-value less than 0.05.

本研究采用基于医疗机构的非匹配病例对照研究（case-control study）设计，纳入埃塞俄比亚西北部公立助产卫生机构分娩的342名产后女性，其中病例组108例，对照组216例。数据收集环节采用结构化访谈式问卷开展，随后实施二元logistic回归（binary logistic regression）分析。以校正后比值比（adjusted odds ratio）结合95%置信区间（95% confidence interval）评估自变量与结局变量间的统计学关联，并以p值小于0.05作为显著性判定标准。
