Smoking during pregnancy has been linked to serious adverse health outcomes for mother and baby. This study aims to examine the individual and pregnancy characteristics associated with not smoking or ceasing smoking during pregnancy among Aboriginal and Torres Strait Islander women in Australia.
A cross-sectional secondary analysis of data was conducted. Records were included if the mother was Aboriginal and /or Torres Strait Islander and had smoking status recorded. The individual and pregnancy characteristics associated with not smoking or ceasing smoking during pregnancy were assessed using mixed model logistic regressions.
A total of 49 651 women with a median age of 25 years were included. Overall, 56% (n = 27 782) reported not smoking during pregnancy and 13% reported ceasing smoking during pregnancy. The odds of not smoking were increased for those who were older, had fewer previous pregnancies, were married or in a de facto relationship, were private patients, had higher BMI, were diagnosed with hypertension, attended more antenatal care visits and began antenatal care earlier in pregnancy. The odds of ceasing smoking were higher for those who were married or in a defacto relationship, were private patients, began antenatal care earlier in pregnancy, had a lower number of pregnancies and were diagnosed with hypertension.
A variety of sociodemographic, health, and antenatal care factors were associated with smoke-free pregnancies among Aboriginal and Torres Strait Islander women. These findings inform targeted interventions and policies to enhance efforts to promote smoke-free pregnancies among Aboriginal and Torres Strait Islander women.
Understanding the factors associated with not smoking among pregnant Aboriginal and Torres Strait Islander woman can inform the development of strategies to address the harmful effects of smoking during pregnancy. This secondary analysis found consideration of strategies such as tailoring supports to those who are younger or not married, evaluating programs run by different jurisdictions and addressing barriers to receiving early and consistent antenatal care may be useful for informing the development of targeted interventions and policies and tailoring cessation support approaches.
孕期吸烟与母婴严重不良健康结局相关。本研究旨在调查澳大利亚原住民和托雷斯海峡岛民妇女孕期不吸烟或戒烟的个体及妊娠特征。
对数据进行横断面二次分析。纳入母亲为原住民和/或托雷斯海峡岛民且有吸烟状况记录的病例。采用混合模型逻辑回归评估孕期不吸烟或戒烟的个体及妊娠特征。
共纳入49651名女性，中位年龄为25岁。总体而言，56%（n = 27782）报告孕期不吸烟，13%报告孕期戒烟。年龄较大、既往妊娠次数较少、已婚或处于事实婚姻关系、为私立患者、BMI较高、被诊断为高血压、产前检查就诊次数较多且孕期较早开始产前检查的女性不吸烟的几率增加。已婚或处于事实婚姻关系、为私立患者、孕期较早开始产前检查、妊娠次数较少且被诊断为高血压的女性戒烟的几率较高。
多种社会人口学、健康及产前检查因素与澳大利亚原住民和托雷斯海峡岛民妇女的无烟妊娠相关。这些发现为有针对性的干预措施和政策提供了依据，以加强促进澳大利亚原住民和托雷斯海峡岛民妇女无烟妊娠的努力。
了解与澳大利亚原住民和托雷斯海峡岛民孕妇不吸烟相关的因素可为制定应对孕期吸烟有害影响的策略提供参考。这项二次分析发现，考虑为年轻或未婚者量身定制支持措施、评估不同司法管辖区开展的项目以及解决获得早期和持续产前检查的障碍等策略，可能有助于为制定有针对性的干预措施和政策以及量身定制戒烟支持方法提供参考。
