Unintended pregnancy is a major driver of poor maternal and child health in resource-limited settings. Data on pregnancy intention and use of family planning (FP) is scarce in Papua New Guinea (PNG), but are needed to inform public health strategies to improve FP accessibility and uptake. Data from a facility-based cross-sectional sample of 699 pregnant women assessed prevalence and predictors of unintended pregnancy and modern FP use among pregnant women in East New Britain Province, PNG. More than half (55%) the women reported their pregnancy as unintended. Few (18%) reported ever having used a modern FP method, and knowledge of different methods was low. Being single, separated or divorced (AOR 9.66; 95% CI 3.27-28.54), educated to a tertiary or vocational level (AOR 1.78 CI 1.15-2.73), and gravidity > 1 (AOR 1.43 for each additional pregnancy CI 1.29-1.59) were associated with unintended pregnancy; being accompanied by a male partner to ANC was associated with a reduced unintended pregnancy (0.46 CI 0.30-0.73). Factors associated with modern FP use included male partner involvement (AOR 2.26 CI 1.39-3.67) and gravidity > 1 (AOR 1.54 for each additional pregnancy CI 1.36-1.74). FP use also varied by the facility women attended. Findings highlight an urgent need for targeted interventions to improve FP knowledge, uptake and access, and male partner involvement, to reduce unintended pregnancies and their complications.
意外怀孕是资源有限环境下母婴健康不良的主要驱动因素。巴布亚新几内亚（PNG）关于妊娠意愿和计划生育（FP）使用的数据稀缺，但需要这些数据来为改善 FP 可及性和使用率的公共卫生策略提供信息。这项研究的数据来自东新不列颠省（PNG）的一家医疗机构的 699 名孕妇的横断面样本，评估了意外妊娠的流行率及其预测因素，以及现代 FP 在孕妇中的使用情况。超过一半（55%）的女性报告说她们的怀孕是意外的。很少（18%）的人报告曾经使用过现代 FP 方法，而且对不同方法的了解也很低。单身、分居或离婚（AOR 9.66；95%CI 3.27-28.54）、接受过高等或职业教育（AOR 1.78 CI 1.15-2.73）、怀孕次数超过一次（每次怀孕的 AOR 为 1.43，95%CI 为 1.29-1.59）与意外怀孕有关；在 ANC 时由男性伴侣陪同与意外怀孕减少有关（0.46 CI 0.30-0.73）。与现代 FP 使用相关的因素包括男性伴侣的参与（AOR 2.26 CI 1.39-3.67）和怀孕次数超过一次（每次怀孕的 AOR 为 1.54，95%CI 为 1.36-1.74）。FP 的使用也因妇女就诊的机构而异。研究结果强调迫切需要有针对性的干预措施，以提高 FP 知识、使用率和可及性，并促进男性伴侣的参与，以减少意外怀孕及其并发症。
