Smoking during pregnancy poses serious health risks for mother and baby. Addressing smoking among pregnant Aboriginal and Torres Strait Islander women is an Australian national priority. This study aimed to understand the geographical variation in rates of not smoking during pregnancy among Aboriginal and Torres Strait Islander women.
Data from the National Perinatal Data Collection were obtained for all births in Australia recorded between 2014 and 2017 to women aged 18 and over who were recorded as Aboriginal and/or Torres Strait Islander. Sociodemographic characteristics were obtained from national data for each of the 340 included geographic areas of residence (SA3). The characteristics associated with not smoking in the first 20 weeks of pregnancy were explored with conditional autoregressive spatial regression modelling.
Over half (56%) of the 49 341 women included in the dataset reported they did not smoke in the first 20 weeks of pregnancy. The prevalence of not smoking ranged from 39% to 86% across geographic areas. Not smoking was highest in areas with higher median age, lower levels of socio-economic disadvantage and increased participation in employment.
Not smoking during the first 20 weeks of pregnancy among Aboriginal and Torres Strait Islander women was strongly associated with area-level socioeconomic disadvantage driven primarily by the level of employment in the area. SO WHAT?: Targeted public health strategies that focus on areas identified as having high rates of maternal smoking and on improving employment opportunities and addressing socioeconomic disadvantage could contribute to a reduction in smoking rates.
孕期吸烟会给母亲和婴儿带来严重的健康风险。解决澳大利亚原住民和托雷斯海峡岛民孕妇的吸烟问题是一项国家重点工作。本研究旨在了解原住民和托雷斯海峡岛民孕妇孕期不吸烟率的地理差异。
从国家围产期数据收集中获取2014年至2017年期间澳大利亚记录的所有18岁及以上被记录为原住民和/或托雷斯海峡岛民的妇女的分娩数据。社会人口学特征来自于所纳入的340个居住地理区域（统计区3级）的国家数据。采用条件自回归空间回归模型探讨与孕期前20周不吸烟相关的特征。
数据集中纳入的49341名妇女中，超过一半（56%）报告称她们在孕期前20周不吸烟。各地理区域不吸烟的患病率在39%至86%之间。在年龄中位数较高、社会经济劣势水平较低且就业参与度较高的地区，不吸烟率最高。
原住民和托雷斯海峡岛民妇女在孕期前20周不吸烟与地区层面的社会经济劣势密切相关，主要由该地区的就业水平驱动。那么怎么办呢？：针对被确定为孕妇吸烟率高的地区、改善就业机会以及解决社会经济劣势的有针对性的公共卫生策略，可能有助于降低吸烟率。
