摘要
目的了解甘肃省定西市岷县2013~2019年农村计划妊娠初产妇怀孕年龄流行趋势。方法以2013~2019年参加国家免费孕前优生健康检查项目的2992例岷县20~49岁农村汉族计划妊娠初产妇为研究对象,计算2013~2019年的平均怀孕年龄;使用简单线性回归模型分析其年度变化趋势,广义线性回归模型分析经过调整的年度变化趋势;并采用边际效应模型,以2016年的研究对象为参照,分析其它年份参检对象怀孕年龄的边际值,使用简单线性回归模型计算边际值的年度变化趋势。结果怀孕年龄从2013年的22.92(22.65~23.20)岁推迟到2019年的24.57(24.28~24.86)岁(P_(趋势)<0.05),怀孕年龄绝对推迟了1.65(1.24~2.04)岁;调整后的年均增长为0.20(0.15~0.25)岁。以2016年的参检对象为参照对象,怀孕年龄的边际效应从2013年的-0.36(-0.77~0.05)岁上升到2019年的0.70(0.31~1.09)岁(P_(趋势)<0.05),年均增长0.20(0.12~0.29)岁。结论岷县农村计划妊娠初产妇怀孕年龄明显推迟,妇幼保健机构应采取积极性的措施,以应对不断推迟的怀孕年龄和增多的相关不良孕产事件。
Objective To analyze the trend of pregnancy age in rural planned pregnancy primiparas of Min county,Dingxi City,Gansu province from 2013 to 2019.Methods A total of 2992 rural Han primiparas and participated in the National Free Pre-pregnancy Checkups Project in Min County from 2013 to 2019 was included.And the yearly pregnancy ages of the participants were calculated.Both simple linear regression and generalized linear model were applied to test the temporal trend of the pregnancy age.In addition,marginal effects model was used to analyze the pregnancy age difference of the participants for each year compared to participants in 2016,simple linear regression model was used to calculate the annual trend of marginal values.Results Average pregnancy age has increased from 22.92(22.65~23.20)years in 2013 to 24.57(24.28~24.86)years in 2019(P_(trend)<0.05),and the pregnancy age absolute increment and the adjusted annual growth were 1.65(1.24~2.04)years and 0.20(0.15~0.25)years,respectively.Compared to participants in 2016,the difference of pregnancy age has expanded from-0.36(-0.77~0.05)in 2013 to 0.70(0.31~1.09)in 2019(P_(trend)<0.05),with an annual increasing of 0.20(0.12~0.29)years on average.Conclusion Pregnant age in rural primiparas of Min County gradually postponed in recent years,which call for maternity and children care policy-makers to take positive actions on the rising events of adverse maternal and fetal outcomes.
