Background: Recent advances in medical sciences have increased the survival of premature infants. Long-term follow-up is very important for decreasing the consequences of prematurity. Objectives: The present study aimed at investigating common post-discharge problems of premature neonates. Methods: In this prospective descriptive study, we selected preterm infants with a gestational age of < 34 weeks or birth weight of < 2,000 g referring to a high-risk neonatal follow-up clinic of Mahdieh Hospital from 2016 to 2017. Growth indices and other medical problems were evaluated. Results: Of 140 newborns, 51.4% were males. The mean gestational age and birth weight were 30 weeks and 1,366.99 g, respectively. The mean interval between the discharge and the referral time to the clinic was 6.16 days with a range of 1 to 45 days. The maximum number of visits of a patient to the clinic was 18 times. The first visit occurred at 2-3 days after the discharge and the oldest age of patients at outpatient visits was 36 months. Although the growth level of most patients at birth was in the 50th percentile of growth charts, the impairment of growth indices was detected after discharge, particularly in neonates with birth weights of < 1,000 g. The rate of exclusively breastfed infants was 17% while 83% were fed by the formula. Re-admission was observed in 26.4%. Infantile colic, gastroesophageal reflux, respiratory allergy, and hypothyroidism were observed in 25%, 22.1%, 3.6%, and 2.9% of the infants, respectively, and 6.6% needed surgical intervention. The rate of late anemia was 45.7%, with 26.4% requiring packed cell transfusion. Conclusions: Our study revealed that the rate of regular post-discharge follow-ups of preterm infants was low. Regarding growth impairments of preterm neonates, special attention to nutrition is recommended after discharge from the hospital. Given the low rate of exclusive breastfeeding of premature infants, comprehensive planning to raise the rate of feeding with breast milk is very important. Regarding the high rate of anemia and the need for packed cell transfusion, paying attention to good nutrition and iron supplementation is crucial after discharge.

Introduction: Despite medical advances, preterm delivery remains a global problem in developed and developing countries. The present study was aimed at conducting a systematic review and meta-analysis of studies on the prevalence of preterm delivery in Iran. Methods: This study was carried out on studies conducted in Iran by searching databases of SID, Magiran, Irandoc, MEDLIB, Iranmedex, PubMed, Web of science, Google Scholar and Scopus. The search was conducted using advanced search and keywords of preterm delivery and equivalents of it in Mesh and their Farsi’s Synonymous in all articles from 2000-2016.After extracting the data, the data were combined using a random model. Heterogeneity of the studies was assessed using Q test I2 index and the data were analyzed using STATA Ver.11 software. Results: The total number of samples in this study was 41773. In 19 reviewed articles, the overall prevalence of preterm delivery, based on the random effects model, was estimated to be a total of 10% (95% CI, 9-12). The lowest prevalence of preterm labor was 5.4% in Bam and the highest prevalence was 19.85% in Tehran. There was no significant difference between the prevalence of preterm delivery compared to year of study and sample size. Conclusion: This study reviewed the findings of previous studies and showed that preterm delivery is a relatively prevalent problem in Iran. Therefore, adopting appropriate interventions in many cases including life skills training, self-care and increasing pregnancy care to reduce these consequences and their following complications in high risk patients seem necessary.
