【摘要】：目的了解中国部分地区出生人口性别比状况及其影响因素。方法采用分层、随机整群抽样方法,在内蒙古、江苏、甘肃,贵州及黑龙江省5个省份各抽取1个城市,于2009年3—6月以2006—2008年出生的17 093名婴幼儿及其父母为调查对象进行调查。结果 5个城市2006—2008年平均出生人口性别比为119.48。男、女婴在不同地区、不同胎次及不同民族间分布有差异(P0.05);性别比在织金县最高(163.4),常州市最低(108.65);在不同胎次间≥3胎最高(199.6),第1胎最低(112.63);在不同民族中穿青族最高(176.41),蒙古族最低(106.01)。多因素logistic回归分析结果表明,影响性别比升高的因素有引产史(OR=1.579)、高胎次(2胎OR=1.261,≥3胎OR=1.395)、父母偏爱男孩(父亲OR=1.580,母亲OR=1.772)、父亲低文化程度(9年OR=1.244,9~12年OR=1.336)、父母偏好女孩(父亲OR=0.504、母亲OR=0.544)。结论有引产史、高胎次、父母偏爱男孩、父亲低文化程度会使生育男孩的可能性增大,使出生人口性别比升高;父母偏好女孩会使生育女孩的可能性增大,从而降低出生人口性别比。
[Abstract]:Objective to investigate the sex ratio of birth population in some areas of China and its influencing factors. Methods A stratified and random cluster sampling method was used to select one city in each of the five provinces of Inner Mongolia, Jiangsu, Gansu, Guizhou and Heilongjiang. From March to June 2009, 17,093 infants and their parents who were born in 2006-2008 were investigated. Results the average sex ratio of birth population in five cities was 119.48 in 2006-2008. Boys and girls in different regions, The sex ratio was the highest in Zhijin County (163.4), the lowest in Changzhou City (108.65), the highest (199.6), the lowest (112.63) in the first trimester, the highest (176.41) in the different nationalities and the lowest (106.01) in the Mongolian nationality. The results of multivariate logistic regression analysis showed that the factors influencing the increase of sex ratio were history of induced labor (OR=1.579), high birth order (OR=1.261, 鈮，
