摘要
目的 了解我国高龄产妇比率的动态变化趋势。方法采用以医院为基础的出生缺陷监测方法收集资料，对1996-2007年高龄（≥35岁）产妇数进行回顾性分析。对全国及城乡高龄产妇比率分别进行卡方趋势检验，以了解高龄产妇比率的长期变化趋势，并对全国高龄产妇比率进行拟合模型分析。对东、中、西部地区及其城乡的高龄产妇的比率，也分别进行卡方趋势检验。结果1996-2007年全国460余所医院共监测出生数6308594名，其中高龄产妇数354511名，占5．62％。1996年和2007年高龄产妇比率分别为2．96％（12508／422486）和8．56％（66351／775333），1996～2007年呈逐年增长趋势（X^2=45376．16，P〈0．01）。城市1996年和2007年高龄产妇比率分别是2．95％（8755／296975）和7．69％（40197／522596），1996-2007年呈逐年增长趋势（X^2=24152．86，P〈0．01）。农村1996年和2007年高龄产妇比率分别是2．99％（3753／125511）和10．35％（26154／252737），1996-2007年呈逐年增长趋势（X^2=20809．79，P〈0．01）。城市高龄产妇比率为5．13％（221655／4317533），农村高龄产妇比率为6．67％（132856／1991061），城乡地区的高龄产妇比率差异有统计学意义（x^2=1536．260，P〈0．叭）。模型拟合分析得指数模型为ln（Y）=in（2．52）＋（0．103×t）。我国东部1996年和2007年高龄产妇比率分别为3．90％和8．81％，中部分别为2．49％和8．56％，西部分别为2．11％和8．21％，东、中、西部地区高龄产妇比率均有逐年增长趋势（x^2值分别为11746．87、17350．21、／6432．68，P值均〈0．01）。结论 我国总体高龄产妇比率都呈逐年增长趋势，城市高龄产妇比率低于农村。
Objective To investigate the secular trend of advanced maternal age woman （ ≥ 35 year-old） in our country. Methods Data on maternal woman at different age were collected at surveillance hospital in Chinese Birth Defects Monitoring Network from 1996 to 2007 and retrospective analysis of the trend of advanced maternal women were carried out. Trend analysis of the advanced maternal age in urban and rural areas of west, middle and east areas was also conducted. Chi-square test was applied to test the differences and the fitting model analysis was also applied. Results A total of 6 308 594 parturient woman were monitored, included 354 511 woman （5.62%） of advanced maternal age. In 1996 and 2007, the proportion of the advanced maternal woman were 2.96% （12 508/422 486） and 8.56% （66 351/775 333 ） , respectively. It showed an increasing trend for the national woman proportion of advanced maternal age from 1996 to 2007（ X2 =45 376. 16 ,P 〈0. 01 ）. In city,the proportion of advanced maternal age woman were 2. 95 % （ 8755/296 975 ） and 7.69% （40 197/522 596 ） in 1996 and 2007, respectively. In rural region, the proportion of advanced maternal age woman were 2. 99% （3753/125 511 ） and 10. 35% （26 154/252 737） in 1996 and 2007, respectively. It showed increasing both in city and rural areas （ Xcity = 24 152.86, P 〈 0. 01; Xrural = 20 809. 79,P 〈 0. 01 ）. And the proportions in urban area and rural area were 5.13% （221 655/4 317 533 ） and 6. 67% （132 856/1 991 061 ） , the proportions difference was significant in statistics （X^2 = 1536. 260,P 〈0. 01 ）. An Exponential model was established,In（Y） = ln（2. 52） ＋ （0. 103 ×t）. In east areas, the proportion were 3.90% and 8.81% in 1996 and 2007, respectively, in middle areas the respective proportions were 2.49% and 8. 56%, in west areas were 2. 11% and 8.21%. They all showed increasing trend in proportion of advanced maternal age from 1996 to 2007 year in east areas, middle areas and west areas （X2east =11 746. 87,P 〈 0. 01 ; X2middle= 17 350. 21, P 〈 0. 01 ; X2west = 16 432. 68,P 〈 0. 01 ）. But the proportions of city and rural were different in those areas. Conclusion The proportion of advanced maternal woman had secular increasing trend and the rates were lower in city than in rural areas.
