RESUMEN
OBJECTIVE: To evaluate the percentage of children born extremely preterm (EP) who screen positive for ≥1 DSM-IV psychiatric disorders, the co-occurrence of and sex-related differences in these classifications, and the functional correlates of psychiatric symptoms. METHODS: The Extremely Low Gestational Age Newborn (ELGAN) Study is a prospective cohort follow-up of children born <28 weeks' gestation. For 871 10-year-old children, parents completed the Child Symptom Inventory-4 (CSI-4), a child educational/medical history questionnaire, and the Pediatric Quality of Life Inventory (PedsQL). RESULTS: At age 10 years, ELGANs were more likely to screen positive for a number of psychiatric disorders when compared with normative expectations on the CSI-4, with a few sex-related differences. Fifteen percent of participants screened positive for 1 disorder, 7% for 2, 3% for 3, and 4% for ≥4 psychiatric disorders. Compared with children who did not screen positive for psychiatric disorders, children who screened positive for ≥3 psychiatric disorders were approximately twice as likely to have repeated a grade, have an individualized educational program, have an individual school aide, and to require special remediation classes. Children who screened positive for any psychiatric disorder were 4 times more likely to use 1 or more psychotropic medication, and those who screened positive for ≥2 psychiatric disorders had lower PedsQL scores. CONCLUSION: Among 10-year-old children born EP, rates of psychiatric symptoms exceeded normative expectation, and children who screened positive for more than 1 psychiatric disorder were at increased risk of having multiple functional impairments.

OBJECTIVES: Preterm birth appears to contribute to early development of cardiovascular disease, but the mechanisms are unknown. Prematurity may result in programming events that alter the renin-angiotensin system. We hypothesized that prematurity is associated with lower angiotensin-(1-7) in adolescence and that sex and obesity modify this relationship. METHODS: We quantified angiotensin II and angiotensin-(1-7) in the plasma and urine of 175 adolescents born preterm and 51 term-born controls. We used generalized linear models to estimate the association between prematurity and the peptides, controlling for confounding factors and stratifying by sex and overweight/obesity. RESULTS: Prematurity was associated with lower plasma angiotensin II (ß: -5.2âpmol/l, 95% CI: -10.3 to -0.04) and angiotensin-(1-7) (-5.2âpmol/l, 95% CI: -8.4 to -2.0) but overall higher angiotensin II:angiotensin-(1-7) (3.0, 95% CI: 0.9-5.0). The preterm-term difference in plasma angiotensin-(1-7) was greater in women (-6.9âpmol/l, 95% CI: -10.7 to -3.1) and individuals with overweight/obesity (-8.0âpmol/l, 95% CI: -12.2 to -3.8). The preterm-term difference in angiotensin II:angiotensin-(1-7) was greater among those with overweight/obesity (4.4, 95% CI: 0.6-8.1). On multivariate analysis, prematurity was associated with lower urinary angiotensin II:angiotensin-(1-7) (-0.13, 95% CI: -0.26 to -0.003), especially among the overweight/obesity group (-0.38, 95% CI: -0.72 to -0.04). CONCLUSION: Circulating angiotensin-(1-7) was diminished whereas urinary angiotensin-(1-7) was increased relative to angiotensin II in adolescents born preterm, suggesting prematurity may increase the risk of cardiovascular disease by altering the renin-angiotensin system. Perinatal renin-angiotensin system programming was more pronounced in women and individuals with overweight/obesity, thus potentially augmenting their risk of developing early cardiovascular disease.

OBJECTIVE: To evaluate the correlates of a clinically significant high score on the Social Responsiveness Scale (SRS) in 10-year-old children who were born extremely preterm and who did not meet criteria for autism spectrum disorder (ASD). METHODS: After excluding 61 participants diagnosed with ASD, we grouped children by IQ < or ≥85 and then compared the prevalence of neurocognitive and other deficits between those who had SRS total and component scores ≥65 and their peers who had lower scores. RESULTS: Among children who had IQ ≥ 85, the prevalence of SRS total scores ≥65 was 16% (n = 103/628), and among children who had IQ < 85, it was 27% (n = 40/148), higher than the 4% prevalence expected based on normative population data. Among children who had IQ ≥ 85, those who had high SRS scores more often than their peers had deficits in attention and executive function, and language and communication, and they were more often rated by their parents and teachers as having behavioral (e.g., attention-deficit hyperactivity disorder [ADHD]) and emotional (e.g., anxiety and depression) problems. CONCLUSION: Social Responsiveness Scale-defined social impairment was much more common in our cohort of 10-year-old children born extremely preterm than was expected based on general population norms. High SRS scores were characteristic of children who had intellectual, neurocognitive, language, and communication limitations, as well as deficits in behavior and emotion regulation.
