The objective of the study was to determine whether a history of unplanned pregnancy was a risk factor for a subsequent unplanned pregnancy.
We analyzed 542 women aged 14-35 years, enrolled in Project PROTECT, a randomized clinical trial to promote dual-method contraception use to prevent sexually transmitted diseases and unplanned pregnancy. Predictors of unplanned pregnancy were assessed by comparing women with and without a history of unplanned pregnancy.
More than 1 in 5 women (22.5%) experienced an unintended pregnancy. History of an unintended pregnancy was a predictor of unintended pregnancy (adjusted odds ratio, 1.91; 95% confidence interval, 1.09-3.34). Other factors that were significantly associated with unplanned pregnancy included young age and low educational status.
Future efforts should focus on bridging the gap between identifying risk factors for unplanned pregnancy and interventions aimed at reducing the incidence in high-risk groups.
本研究的目的是确定意外怀孕史是否是后续意外怀孕的危险因素。
我们分析了542名年龄在14至35岁之间的女性,她们参与了“保护计划”项目,这是一项随机临床试验,旨在推广使用双重避孕方法以预防性传播疾病和意外怀孕。通过比较有和没有意外怀孕史的女性来评估意外怀孕的预测因素。
超过五分之一的女性(22.5%)经历过意外怀孕。意外怀孕史是意外怀孕的一个预测因素(调整后的优势比为1.91;95%置信区间为1.09 - 3.34)。与意外怀孕显著相关的其他因素包括年轻和教育程度低。
未来的努力应集中在缩小识别意外怀孕危险因素与旨在降低高危人群发生率的干预措施之间的差距上。
