AIHW - Maternity Indicators - Smoking in the First 20 Weeks of Pregnancy for Women Giving Birth (%) (SA3) 2014-2016

This dataset presents the footprint of the percentage of women who gave birth and reported smoking tobacco in the first 20 weeks of pregnancy, by the mother's usual residence. This has been calculated with the number of females who gave birth and reported smoking in the first 20 weeks of pregnancy, divided by the total number of females who gave birth, and multiplied by 100. The data spans the years of 2014-2016 and is aggregated to Statistical Area Level 3 (SA3) geographic areas from the 2011 Australian Statistical Geography Standard (ASGS).\n\nThe data is sourced from the National Perinatal Data Collection (NPDC), which is a national population-based cross-sectional collection of data on pregnancy and childbirth. The data are based on births reported to the perinatal data collection in each state and territory in Australia. Midwives and other birth attendants, using information obtained from mothers and from hospital or other records, complete notification forms for each birth. A standard de-identified extract is provided to the Australian Institute of Health and Welfare (AIHW) on an annual basis to form the NPDC.\n\nFor further information about this dataset, please visit:\n\n * [Australian Institute of Health and Welfare - National Core Maternity Indicators Data Tables.](https://www.aihw.gov.au/reports/mothers-babies/ncmi-data-visualisations/data)\n\n * [Metadata Online Registry Entry.](https://meteor.aihw.gov.au/content/index.phtml/itemId/690056)\n\nPlease note:\n\n * AURIN has spatially enabled the original data using the [Department of Health - PHN Areas.](https://www1.health.gov.au/internet/main/publishing.nsf/Content/PHN-Home)\n\n * A birth is defined as an event in which a baby comes out of the uterus after a pregnancy of at least 20 weeks gestation or weighing 400 grams or more.\n\n * Smoking refers to the use of cigarettes or inhaled tobacco.\n\n * Data excludes mothers whose smoking status was not stated.\n\n * Smoking during pregnancy is self-reported smoking of tobacco.\n\n * Because of differences in definitions and methods used for data collection, care must be taken when comparing across jursidictions.\n\n * Data for Statistical Local Area Level 3 (SA3) of mother's usual residence reported using a 3 year aggregate, 2014-2016.\n\n * The sum of the reported 'Grouped by' values may not equal the Australia total.\n

本数据集呈现了按产妇常住地划分的、妊娠前20周报告吸烟的分娩女性占比情况。该占比的计算方式为：妊娠前20周报告吸烟的分娩女性人数除以总分娩女性人数，再乘以100。本次数据覆盖2014至2016年，聚合自2011年版澳大利亚统计地理标准（Australian Statistical Geography Standard, ASGS）下的三级统计区域（Statistical Area Level 3, SA3）。

本数据集源自国家围产期数据收集计划（National Perinatal Data Collection, NPDC），该计划是一项基于全国人口的妊娠与分娩横断面数据收集项目。数据基于澳大利亚各州及领地上报至围产期数据收集系统的分娩记录：助产士及其他接生人员通过产妇提供的信息以及医院或其他相关记录，填写每份分娩的上报表格。经标准化去标识化的数据提取文件会按年度提交至澳大利亚卫生与福利研究所（Australian Institute of Health and Welfare, AIHW），以此构建国家围产期数据收集计划的数据库。

请注意：
* 澳大利亚城市与区域信息网络（AURIN）已依据卫生部门的初级保健网络（Primary Health Network, PHN）区域对原始数据完成空间化处理。
* 分娩定义为：妊娠至少20周或胎儿体重达到400克及以上时，胎儿经子宫娩出的事件。
* 吸烟指吸食香烟或吸入烟草制品的行为。
* 本数据集未纳入吸烟状态未明确的产妇。
* 妊娠期间吸烟指产妇自我报告的烟草吸食行为。
* 由于各司法管辖区在数据收集的定义与方法上存在差异，跨区域对比数据时需谨慎。
* 产妇常住地的三级统计区域（Statistical Local Area Level 3, SA3）相关数据采用2014-2016年三年聚合数据上报。
* 按「分组维度」汇总的报告值总和可能与澳大利亚全国总计并不一致。
