This study aims to explore the potential association between unintended pregnancy and maternal health complications. Secondarily, we test whether antenatal care (ANC) and community health worker (CHW) visits moderate the observed association between unintended pregnancy and maternal health complications. Cross sectional data were collected using a multistage sampling design to identify women who had a live birth in the last 12 months across 25 highest risk districts of Uttar Pradesh (N = 3659). Participants were surveyed on demographics, unintendedness of last pregnancy, receipt of ANC clinical visits and community outreach during pregnancy, and maternal complications. Regression models described the relations between unintended pregnancy and maternal complications. To determine if receipt of ANC and CHW visits in pregnancy moderated associations between unintended pregnancy and maternal complications, we used the Mantel-Haenzel risk estimation test and stratified logistic models testing interactions of unintended pregnancy and receipt of health services to predict maternal complications. Around one-fifth of the women (16.9%) reported that their previous pregnancy was unintended. Logistic regression analyses revealed that unintended pregnancy was significantly associated with maternal complications- pre-eclampsia (AOR:2.06; 95% CI:1.57–2.72), postpartum hemorrhage (AOR:1.46; 95% CI: 1.01–2.13) and postpartum pre-eclampsia (AOR:2.34; 95% CI:1.47–3.72). Results from the Mantel Haenszel test indicated that both ANC and CHW home visit in pregnancy significantly affect the association between unintended pregnancy and postpartum hemorrhage (p < 0.001). Unintended pregnancy is associated with increased risk for maternal health complications, but provision of ANC clinical visits and CHW home visits in pregnancy may be able to reduce potential effects of unintended pregnancy on maternal health.

意外怀孕和孕产妇健康并发症：印度北方邦农村数据的横断面分析


本研究旨在探讨意外怀孕与孕产妇健康并发症之间的潜在关联。其次，我们测试产前护理 (ANC) 和社区卫生工作者 (CHW) 就诊是否会调节观察到的意外怀孕与孕产妇健康并发症之间的关联。采用多阶段抽样设计收集横断面数据，以确定北方邦 25 个最高风险地区过去 12 个月内活产的妇女 (N = 3659)。对参与者进行了人口统计、上次怀孕的意外情况、怀孕期间接受 ANC 临床就诊和社区外展以及孕产妇并发症等方面的调查。回归模型描述了意外怀孕与产妇并发症之间的关系。为了确定怀孕期间接受 ANC 和 CHW 就诊是否会调节意外怀孕和孕产妇并发症之间的关联，我们使用 Mantel-Haenzel 风险估计测试和分层逻辑模型测试意外怀孕和接受卫生服务之间的相互作用来预测孕产妇并发症。大约五分之一的女性（16.9%）表示她们之前的怀孕是意外的。 Logistic 回归分析显示，意外怀孕与孕产妇并发症显着相关：先兆子痫（AOR：2.06；95% CI：1.57–2.72）、产后出血（AOR：1.46；95% CI：1.01–2.13）和产后出血。子痫（AOR：2.34；95% CI：1.47–3.72）。 Mantel Haenszel 测试的结果表明，ANC 和 CHW 妊娠期家访均显着影响意外妊娠与产后出血之间的关联 (p < 0.001)。 意外怀孕与孕产妇健康并发症的风险增加有关，但在怀孕期间提供 ANC 临床就诊和社区卫生工作者家访可能能够减少意外怀孕对孕产妇健康的潜在影响。
