摘要
目的探讨妊娠年龄对妊娠并发症及后代的影响。方法800名孕妇随机分为:Ⅰ:20—25岁,Ⅱ:26~30岁,Ⅲ:31.35岁,Ⅳ:〉35岁,每组各200名。一方面回顾性分析年龄对并发症的影响;另一方面在婴儿出生后6、12、18、24、30个月进行智力发育指数(Mental development index,MDI)和精神运动发育指数(Psychomotor development index,PDI)评估。结果Ⅰ,Ⅳ组并发症显著高于其他组(Ⅰ:χ^2=199.46,P〈0.05,Ⅳ:χ^2=211.33,P〈0.01)。Ⅳ组MDI,PDI在6、12、24个月时显著性低于其他组(MDI:F=2.37—3.57,q=4.37~5.01,P〈0.05;PDI:F=2.76~3.00,q=4.73—6.27,P〈0.05);Ⅳ组婴儿MDI〈85者12例,PDI〈70者6例,诊断为精神发育迟滞。结论妊娠年龄大于35岁将显著提高并发症且对后代有不利影响。
Objective To explore the effects of pregnant age on the pregnancy complications and their infants. Methods All of 800 mothers were divided into four groups by the pregnant age: Ⅰ : 20-25 years old, Ⅱ:26-30 years old, Ⅲ 31-35 years old,Ⅳ:〉35 years old,200 for each group. First,we had a retrospective analysis to explore the effect of pregnant age on the rate of Pregnancy complications;Second,the infants had Mental Development Indcx(MDI) and Psychomotor Development Index (PDI) test at 6,12, 18,24 and 30month after birth. Results Ⅰ , Ⅳ group had an significant higher rate of Pregnancy complications than the other groups ( Ⅰ : χ^2=199.46,P〈0.05; Ⅳ: χ^2=211.33,P〈0.01). The MDI and PDI of infants in group Ⅳ was significant lower as compared with the other groups at 6,12,24 month after birth (MDI:F=2.37-3.57,q=4.37-5.01,P〈0.05. PDI:F=2.76-3.00,q=4.73-6.27,P〈0.05).There were 12 infants whose MDI was lower than 85 in Group Ⅳ and 6 babes whose MPI was lower than 70,those babes were dignified as mental retardation. There was no significant difference between MDI and PDI among the infants of group Ⅰ , Ⅱ and Ⅲ. Conclusion The age of pregnant mothers over 35 years old will significantly increase the incidence of complications and has adverse effects on the intelligence development of their infants.
