METHODS: All live births during one week in 1995 (n=13,318), 2003 (n=14,737), 2010 (n=14,903) and 2016 (n=13,384). Data were from interviews of women in postpartum wards and from medical records and were compared between years.
RESULTS: Between 1995 and 2016, maternal age and body mass index increased steadily. Pregnancies that occurred with use of contraception increased from 7.4% in 2010 to 9.3% in 2016. Smoking during pregnancy (16.6%) did not decrease since 2010. The frequency of more than three ultrasounds during pregnancy was 48.5% in 1995 and 74.7% in 2016. Deliveries in large public hospitals increased steadily. The caesarean section rate has been relatively stable since 2003 (20.4% in 2003, 21.1% in 2010 and 20.4% in 2016). The rate of induction of labour was 22% in 2010 and 2016. Overall, 83.8% of women had epidural analgesia/anaesthesia in 2016. Rates of pre-term birth in 2016 ranged from 7.5% among all live births to 6.0% among live born singletons; for singletons, this rate increased steadily from 1995 to 2016, whereas there was no clear trend for low birth weight. Exclusive breastfeeding decreased from 60.3% in 2010 to 52.2% in 2016.
CONCLUSIONS: Routine national perinatal surveys highlight successful policies and recommendations but also point out some health indicators, practices, preventive behaviours and risk factors that need special attention.
方法:1995年一周内所有活产婴儿(n=13,318),2003年(n=14,737),2010年(n=14,903)和2016年(n=13,384)。数据来自产后病房妇女的访谈和医疗记录,并在年份之间进行了比较。
结果:在1995年至2016年之间,孕产妇年龄和体重指数稳步上升。使用避孕药具发生的怀孕从2010年的7.4%增加到2016年的9.3%。自2010年以来,怀孕期间的吸烟(16.6%)没有减少。怀孕期间三次以上超声检查的频率在1995年为48.5%,在2016年为74.7%。大型公立医院的交付量稳步增长。自2003年以来,剖宫产率相对稳定(2003年为20.4%,2010年为21.1%,2016年为20.4%)。2010年和2016年的引产率为22%。总的来说,2016年,83.8%的女性接受硬膜外镇痛/麻醉。2016年早产率从所有活产的7.5%到活产的单身人士的6.0%不等;对于单身人士,从1995年到2016年,这一比率稳步上升,而低出生体重没有明显趋势.纯母乳喂养从2010年的60.3%下降到2016年的52.2%。
结论:常规国家围产期调查强调了成功的政策和建议,但也指出了一些健康指标,实践,需要特别注意的预防行为和危险因素。
