1983년 5윌 9일부터 1986년 10월 27일까지 약 3년 6개윌간 영남대학교 의과대학 부속병원 산부인과에서 체중 4,000gm 이상의 거대아를 분만한 산모의 병상기록을 중심으로 거대아 임신에 관계되는 요인과 출산에 따르는 문제점을 조사 분석한 결과 다음과 같은 성적을 얻었다. 1. 거대아의 빈도는 체중 4,000gm 이상이 2.8%, 4,500gm 이상이 0.16%이었다. 2. 거대아의 성비는 남아가 65.9%로 전체 신생아의 남아비 53.5%보다 유의성있게 높았다(P<0.05). 3. 임신기간에 따른 거대아 분만 빈도는 임신 기간이 길수록 증가하였으며, 이민 42주와 43주 이상에 출생한 신생아의 분포도 거대아군이 각각 33.3%와 16.6%로 전체 산모에서의 분포 14.2%와 6.2%에 비해 유의성 있게 높았다(P<0.01). 4. 산모의 출산회수에 따른 거대아 분만 빈도는 출산회수가 많을수록 증가하였으며, 초산부(2.35%)와 경산부(3.74%)의 비교에서도 경산부의 거대아 분만빈도가 유의성있게 높았다(P<0.01). 5. 산모의 연령에 따른 거대아 분만빈도는 24세이하, 25~29세, 30세이상에서 각각 2.4%, 3.0%, 2.5%로 차이가 없었다. 6. 거대아의 제왕절개 분만 빈도 30.8%와 흡인 및 감자분만 빈도 31.9%는 기간중의 전체적인 빈도 15.7%와 1.7%에 비해 유의성있게 높았다(P<0.01과 P<0.05). 7. 거대아의 임신 및 출산에 따르는 모성 합병증으로는 산전 빈혈(24.2%), 산후 출혈(11.0%), 산도 손상(10.0%), 분만 제2기의 지연(7.7%)등이 있었으며 모성사망 및 자궁파열의 예는 없었다. 8. 태아 및 신생아 합병증으로는 태아가사 10예(11.0%), 견갑난산 2예, 자궁내 태아사망과 천미골 기형종 각각 1예가 있었다.

Objective: To investigate adverse pregnancy outcomes in non-obese women with polycystic ovary syndrome (PCOS) compared with obese-PCOS and control groups. Methods: Women with PCOS who underwent assisted reproductive technology (ART) from August, 2003 to December, 2007, were considered. A total of 336 women with PCOS were included in the study group and 1,003 infertile women who had tubal factor as an indication for ART were collected as controls. They were divided into four groups: a non-obese PCOS group, obese-PCOS group, non-obese tubal factor group, and obese tubal factor group, with obesity defined by a body mass index over 25 kg/$m^2$, and reviewed focusing on the basal characteristics, ART outcomes, and adverse pregnancy outcomes. Results: There was no difference among the groups' the clinical pregnancy rate or live birth rate. Regarding adverse pregnancy outcomes, the miscarriage rate, multiple pregnancy rate, and prevalence of preterm delivery and pregnancy induced hypertension were not different among the four groups. The incidence of small for gestational age infant was higher in the PCOS groups than the tubal factor groups ($p$ <0.02). On the other hand, the morbidity of gestational diabetes mellitus (GDM) was not high in the non-obese PCOS group but was in the obese groups. And in the obese PCOS group, the newborns were heavier than in the other groups ($p$ <0.02). Conclusion: Non-obese PCOS presents many differences compared with obese PCOS, not only in the IVF-parameters but also in the morbidity of adverse pregnancy outcomes, especially in GDM and fetal macrosomia.

Purpose: The authors analyzed the trend from the birth-related statistics of high birth weight infants (HBWIs) over 50 years in Korea from 1960 to 2010. Methods: We used 2 data sources, namely, the hospital units (1960's to 1990's) and Statistics Korea (1993 to 2010). The analyses include the incidence of HBWIs, birth weight distribution, sex ratio, and the relationship of HBWI to maternal age. Results: The hospital unit data indicated the incidence of HBWI as 3 to 7% in the 1960's and 1970's and 4 to 7% in the 1980's and 1990's. Data from Statistics Korea indicated the percentages of HBWIs among total live births decreased over the years: 6.7% (1993), 6.3% (1995), 5.1% (2000), 4.5% (2000), and 3.5% (2010). In HBWIs, the birth weight rages and percentage of incidence in infants' were 4.0 to 4.4 kg (90.3%), 4.5 to 4.9 kg (8.8%), 5.0 to 5.4 kg (0.8%), 5.5 to 5.9 kg (0.1%), and >6.0 kg (0.0%) in 2000 but were 92.2%, 7.2%, 0.6%, 0.0%, and 0.0% in 2009. The male to female ratio of HBWIs was 1.89 in 1993 and 1.84 in 2010. In 2010, the mother's age distribution correlated with low (4.9%), normal (91.0%), and high birth weights (3.6%): an increase in mother's age resulted in an increase in the frequency of low birth weight infants (LBWIs) and HBWIs. Conclusion: The incidence of HBWIs for the past 50 years has been dropping in Korea. The older the mother, the higher was the risk of a HBWI and LBWI. We hope that these findings would be utilized as basic data that will aid those managing HBWIs.
