“…By contrast, modest increases in the risk of CKD in women exposed to spontaneous preterm deliveries or early term births may be important from a population perspective. Early term births (at 37-38 + 6 weeks) account for about 22% of all births in high-income countries [43], and the majority of preterm and early term births occur spontaneously [14,44].…”

Background: Preterm delivery is an independent risk factor for maternal cardiovascular disease. Little is known about the association between preterm delivery and maternal renal function. This study aimed to examine whether women who experience preterm delivery are at increased risk of subsequent chronic kidney disease (CKD) and endstage kidney disease (ESKD). Methods: Using data from the Swedish Medical Birth Register, singleton live births from 1973 to 2012 were identified and linked to data from the Swedish Renal Register and National Patient Register (up to 2013). Gestational age at delivery was the main exposure and treated as a time-dependent variable. Primary outcomes were maternal CKD or ESKD. Cox proportional hazard regression models were used for analysis. Results: The dataset included 1,943,716 women who had 3,760,429 singleton live births. The median follow-up was 20.6 (interquartile range 9.9-30.0) years. Overall, 162,918 women (8.4%) delivered at least 1 preterm infant (< 37 weeks). Women who had any preterm delivery (< 37 weeks) were at increased risk of CKD (adjusted hazard ratio (aHR) 1.39, 95% CI 1.32-1.45) and ESKD (aHR 2.22, 95% CI 1.90-2.58) compared with women who only delivered at term (≥ 37 weeks). Women who delivered an extremely preterm infant (< 28 weeks) were at increased risk of CKD (aHR 1.84, 95% CI 1.52-2.22) and ESKD (aHR 3.61, 95% CI 2.03-6.39). The highest risk of CKD and ESKD was in women who experienced preterm delivery + preeclampsia (vs. non-preeclamptic term deliveries, for CKD, aHR 2.81, 95% CI 2.46-3.20; for ESKD, aHR 6.70, 95% CI 4.70-9.56). However, spontaneous preterm delivery was also associated with increased risk of CKD (aHR 1.32, 95% CI 1.25-1.39) and ESKD (aHR 1.99, 95% CI 1.67-2.38) independent of preeclampsia or small for gestational age (SGA).

“…Thus, whether early‐term delivery may increase the risk of long‐term cognitive outcome and developmental problems remains less clear. As children born at 37‐38 weeks account for 15%‐31% of all singleton live births, long‐term consequences of early‐term birth affect many children and therefore have significant implications for public health.…”

Introduction Recent recommendations characterize deliveries at 37+0 weeks through 38+6 weeks as early term. We aimed to review the literature systematically on long‐term cognition, school performance and behavior in children born early term (37+0 to 38+6 weeks) compared with full term (39+0 to 40+6 weeks). Material and methods The review was performed according to the PRISMA Statement. The final literature search was performed on 31 January 2019. We located studies in PubMed, Embase, CINAHL and Cochrane Library. Eligible studies were randomized controlled trials, cohort studies and case‐control studies, with outcome assessment performed at 2‐19 years. We collected information using a structured data form and evaluated study quality using the Newcastle‐Ottawa Scale (NOS). Results We included 42 observational studies published between 2006 and 2018. No restriction on year of publication was made. The mean NOS score was 5.8 with a range from 3 to 9. Compared with children born full term, children born early term had a lower intelligence score in early adulthood and up to some 30% increased risk of attention‐deficit/hyperactivity disorder. Furthermore, we found some 10%‐40% increased risk of cognitive problems, some 25% higher risk of language impairments and another 8%‐75% with poorer overall school performance. No meta‐analysis was conducted due to heterogeneity in the outcome measures. Only 10 studies presented subgroup analyses in spontaneous deliveries or adjusted for type of labor onset/induction. Conclusions Children born early term are at increased risk of cognitive deficits, poorer school performance and behavioral problems compared with children born full term.

“…The LPT infants are recognized as the fastest increasing and largest proportion of singleton preterm births [6]. Data from the year 2010 have shown that LPT births accounted for 3.0 to 6.0% of live singleton births and constituted about 65 to 75% of preterm births [7]. The prevalence of LPT is affected by the rate of multiple births.…”

“…The prevalence of LPT is affected by the rate of multiple births. While multiples constitute about 3% of all births, they accounted for about 20% of late preterm births and 5% of early term births [7][8][9].…”

Background: The incidence of preterm births is increasing and has become a global health concern. This study aimed to compare the outcome of late preterm (LPT) to full term (FT) neonates at two large hospitals in Upper Egypt. Results: Out of 250 newborns included in the study, 180 (72%) were FT and 70 (28%) were LPT. More than half of the LPT newborns (52.9%) were admitted to the neonatal intensive care unit (NICU), compared with 26.7% of FT newborns. Delivery of LPT was associated with an increased risk of neonatal morbidity, including jaundice requiring phototherapy (34.3% vs. 7.8%), respiratory morbidities (32.9% vs. 13.9%), hypoglycemia (8.6% vs. 1.7 %), and convulsions (4.3% vs. 0.6%). Conclusions: LPT neonates were more susceptible to suffer from jaundice and respiratory distress among other morbidities. They also had a higher rate of NICU admission, longer duration of NICU stay, as well as a higher mortality rate. The best treatment of late prematurity is to prevent it. Public and professional awareness of the problems associated with late prematurity should be highlighted. Follow-up programs for early detection and intervention for long term complications are recommended.
