UNLABELLED

Birth weight and gestational age are strongly associated with perinatal mortality and morbidity. This study was conducted to survey the vital statistics of premature and low birthweight infants in the Tainan area. Between July 1991 and April 1992, fifteen medical institutions were included on a voluntary basis: eight from level I (obstetric specialty clinic), six from level II (regional hospital), and one from level III (tertiary care center). A total of 14,307 deliveries were enrolled, accounting for about 60% of the total delivery for that year in the area. The proportions of delivery among level I, II and III were 52%, 41% and 7%, respectively. The incidence of premature singleton live birth was 4.6%, and the percentages of gestation between 20-27 weeks, 28-31 weeks and 32-37 weeks were 0.2%, 0.6% and 3.8%, respectively. The premature births accounted for 3.5%, 4.8% and 11.3% of live births at the level I, II and III hospitals, respectively. The incidence of low birthweight and very low birthweight singleton live births was 4.4% and 0.5%, respectively. The low birthweight births accounted for 3.5%, 4.5% and 11.1% of live births at the level I, II and III hospitals, respectively. The data revealed that the higher the level of hospital, the higher incidences of premature and low birthweight infant. Teenage mothers (< 20 year of age) had higher low birthweight rate. The risk of having low birthweight infants decreased progressively in mothers of age < 20 (6.3%), 20-24 (5.4%), 25-29 (4.1%) and 30-34 (3.8%), whereas it became higher in mothers older than 35 (4.8%).

CONCLUSION

The incidence of premature and low birthweight births in the Tainan area was low. Teenager or those with maternal age older than 35 year were high risk groups for producing these infants.

出生体重和孕周与围产期死亡率及发病率密切相关。本研究旨在调查台南地区早产和低体重儿的生命统计数据。1991年7月至1992年4月，15家医疗机构自愿参与：8家一级医疗机构（产科专科诊所）、6家二级医疗机构（地区医院）和1家三级医疗机构（三级护理中心）。共纳入14307例分娩，约占该地区当年分娩总数的60%。一级、二级和三级医疗机构的分娩比例分别为52%、41%和7%。单胎早产活产的发生率为4.6%，孕20 - 27周、28 - 31周和32 - 37周的比例分别为0.2%、0.6%和3.8%。一级、二级和三级医院早产分别占活产的3.5%、4.8%和11.3%。单胎低体重和极低体重活产的发生率分别为4.4%和0.5%。一级、二级和三级医院低体重儿分别占活产的3.5%、4.5%和11.1%。数据显示，医院级别越高，早产和低体重儿的发生率越高。青少年母亲（<20岁）的低体重率较高。年龄<20岁（6.3%）、20 - 24岁（5.4%）、25 - 29岁（4.1%）和30 - 34岁（3.8%）的母亲生育低体重儿的风险逐渐降低，而35岁以上母亲（4.8%）的风险则升高。
