Different morbidity conditions are globally reported from different nations for premature infants. The aim of this study was to identify the relative frequency of some of the most important complications of prematurity in a population of about 1000 of very low birth weight (VLBW; i.e., infants with weight of <1500 g) premature infants in our city and publish the results of the project at the level of the urban community of Isfahan in order to use it for further decisions.
Demographic characteristics and information of prematurity complications of 1000-registered VLBW premature infants were collected and analyzed.
The mean gestational age and birth weight were 30.19 ± 2.26 weeks and 1223.96 ± 227.77 g, respectively. Seven hundred and ninety-eight individuals (79.69%) had respiratory distress syndrome (RDS) which also had the most prevalence frequency, whereas the number of newborns who had chronic lung disease was 80, with the lowest prevalence of 8.01%. The prevalence of infantile mortality was 3.10%.
Regarding advances in medical technologies and caring system, the mortality rate for premature neonates, even VLBW infants, has decreased significantly and survival rates are grown. Alongside the low death rates, managing complications related to prematurity period should be considered more, especially caring for respiratory management should be considered remarkably since RDS stands as the most prevalent disease among them. Efforts also should be made to reduce the number of diseases that worsen the prognosis, such as intraventricular hemorrhage.
全球不同国家报道的早产儿发病情况各异。本研究旨在确定我市约1000名极低出生体重（VLBW，即体重<1500g）早产儿中一些最重要的早产并发症的相对发生率，并在伊斯法罕市社区层面公布该项目结果，以便用于进一步决策。
收集并分析1000例已登记的极低出生体重早产儿的人口统计学特征和早产并发症信息。
平均胎龄和出生体重分别为30.19±2.26周和1223.96±227.77g。798例（79.69%）患有呼吸窘迫综合征（RDS），其发生率也最高，而患有慢性肺病的新生儿数量为80例，发生率最低，为8.01%。婴儿死亡率为3.10%。
随着医疗技术和护理系统的进步，早产儿甚至极低出生体重儿的死亡率显著下降，存活率提高。除了低死亡率外，应更多地考虑处理与早产相关的并发症，尤其是应特别重视呼吸管理护理，因为RDS是其中最常见的疾病。还应努力减少恶化预后的疾病数量，如脑室内出血。
