探讨中孕期妇女与其姻亲关系的现状，分析调节姻亲关系的影响因素。

选择2010年10月至2012年3月在成都市各级医院就诊的1 859名中孕期妇女为研究对象（本研究遵循的程序符合盛行市妇女儿童中心医院崇明分院人体试验委员会所制定的伦理学标准，得到该委员会批准，分组征得受试对象本人的知情同意，并与之签署临床研究知情同意书）。对其进行公婆关系现状进行问卷调查。

中孕期妇女与其公婆关系状况总体比较，差异无统计学意义（t= 1.774，P>0.05），而其与婆婆的亲密度及压力感均明显高于公公（t = 4.909，-6.687;P<0.05）。全职、兼职及其他3种工作状况的中孕期妇女与公公的亲密度比较，差异无统计学意义（t=19.133,P>0.05）,而与公公的压力感及与婆婆的亲密度和压力感比较，差异均有统计学意义（t = 31.853,38.067和35.629;P<0.05），而全职与兼职中孕期妇女与公婆的亲密度和压力感两两比较，差异均有统计学意义（t= 1.318.-2.833,2.475和-3.577；P<0.05）。

中孕期妇女与其公婆关系中亲密度越高者，则压力感越大,且该状况受社会文化因素影响。中孕期妇女及其配偶和公婆作为家庭关系的相互调节者，应彼此相爱、相互理解，建立良好关系，保证妊娠期妇女的身心健康，孕育健康后代。
