Although the effect of early childhood stress on central nervous pain processing is well known, studies on the association of prematurity and chronic pain are scarce. This study used data from a single-centre retrospective cohort study followed by a prospective clinical examination and pain assessment. The study was based on data from the local birth registry. Newborns born between 1969 and 2002 who had reached adulthood were eligible .. Using a selection algorithm, a study cohort stratified by gestational age (GA) was recruited. Chronic pain conditions were assessed using questionnaire and standardized pain drawings. Data on the pre-, peri- and postnatal clinical course was assessed from medical records. Multivariable logistic regression analyses were conducted to investigate associations between prematurity and chronic pain with adjustment for age, gender, socioeconomic status, and perinatal stress factors. 427 participants born preterm and full-term were included (age 28.5 ± 8.7 years). Chronic pain conditions were similarly common between groups with different levels of prematurity (GA ≥ 37 weeks: 34.5 %, GA33-36 weeks: 37.6 %, GA32-29 weeks: 25.2 %, GA < 29 weeks: 30.4 %, p = 0.20). In multivariable analyses, no association between low GA and the presence of chronic pain was found (OR = 0.99 (CI95 %: 0.94-1.04, p = 0.63); this was also true for a subanalysis of widespread pain. While neither fetal nutritional status nor perinatal stressors were associated with pain, exposure to maternal but not paternal smoking during pregnancy was associated with increased risk to develop pain (OR = 2.77 (CI95 %: 1.31-5.88, p = 0.008) in adults born preterm and full-term. This study suggests that prematurity by itself does not increase the risk of chronic pain later in life, but provides preliminary evidence for maternal smoking during pregnancy as risk factor., Competing Interests: Declaration of competing interest The Gutenberg Prematurity Study was supported by the Ernst und Berta-Grimmke Stiftung, Stufe 1 support of the UM and the Else Kröner-Fresenius-Stiftung.

Background: The present study aimed to investigate whether prematurity and perinatal stress exert long-term effects on the onset of panic disorder in later life., Methods: From 40,189 adults born in Germany between 1969 and 2002, a study cohort (n = 427) stratified by gestational age (GA) (extremely preterm: GA < 29 weeks; very preterm: GA 29-32 weeks; moderately preterm: GA 33-36 weeks; and full-term GA ≥ 37 weeks) was selected (age 28.5 ± 8.7 years). Multivariable logistic regression analyses were conducted to investigate associations between gestational age at birth and panic disorder adjusting for age, gender, socioeconomic status, and perinatal factors., Results: The prevalence of panic disorder was roughly equal in moderate to very preterm and full-term birth groups at 1.9%-3.8%. However, this rate significantly increased to 14.3% in the extreme preterm category (GA <2 9: 14.3 %, p = 0.002). In multivariable analyses, female gender and GA were independently associated with panic disorder. Adjusting for age, gender and socioeconomic status, panic disorder was associated with lower GA at birth (OR = 1.12 per week (CI95%: 1.01-1.26, p = 0.037). Whereas adjustment for nutrition status or indicators of perinatal stress had no effect, correction for the length of postnatal ICU-stay eliminated the association between preterm birth and later panic disorder., Limitations: Limitations include the small number of cases and the reliance on questionnaires to assess mental status., Conclusions: Prematurity likely increases the risk of panic disorder later in life, and the subsequent postnatal ICU-stay appears to be of critical importance. However, due to strong collinearity and other associated factors with preterm births, it remains unclear which is the primary determinant., Competing Interests: Declaration of competing interest The authors report no conflict of interest., (Copyright © 2023 The Authors.

Associations of preterm birth with later-life mental distress are well-established. A research gap concerns the role of psychosocial factors such as the family context. This study investigated associations of recalled parental rearing behavior with both preterm birth characteristics and psychological symptom burden later in life. Based on birth registry data of the Mainz University Hospital in Germany (infants born between 1969 and 2002) and using a selection algorithm, a cohort study comprising four gestational age (GA) strata was conducted (≥ 37 weeks: n = 138; 33-36 weeks: n = 132; 29-32 weeks: n = 106; ≤ 28 weeks: n = 132). Participants underwent a medical examination and completed standardized questionnaires. We investigated differences in dimensions of recalled parental rearing behavior according to GA and tested pre-/perinatal stress indicators and recalled parental rearing behavior as statistical predictors of depression and anxiety symptoms later in life. Lower GA was associated with more recalled emotional warmth and overprotection. Recalled emotional warmth was associated with fewer depression and anxiety symptoms, while recalled overprotection co-occurred with more depression symptoms. The findings indicate the relevance of parental rearing behavior for the offspring's mental health. As preterm birth implicates stress for the whole family requiring adaptive parental behavior, the latter could be an important modifiable risk factor., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare., (Copyright © 2023 Elsevier B.V.

Background: Prematurity and the presence of retinopathy of prematurity (ROP) increase the risk for the occurrence of amblyogenic risk factors in childhood and adolescence., Aim: The aim of the present study was to evaluate ocular morbidities and the ophthalmological care of former preterm and full-term persons in adulthood., Material and Methods: The Gutenberg prematurity eye study (GPES) is a retrospective cohort study with a prospective ophthalmological examination of individuals formerly born preterm and full term between 1969 and 2002 (now aged 18-52 years). All participants underwent a detailed ophthalmological examination and were asked about the frequency of ophthalmological care. Participants were grouped into those with normal gestational age (GA) ≥ 37 weeks (control group), preterm individuals without ROP and GA 33-36 weeks (group 2), GA 29-32 weeks (group 3), GA ≤ 28 weeks (group 4), and those with ROP without treatment (group 5) and with ROP with treatment (group 6). All participants were asked if they had an ophthalmological examination within the last 12 months., Results: In total, data from 140 term and 310 preterm adults were included in the present study. Strabismus was present in 2.1 % (3/140), 6.6 % (9/137), 17.4 % (16/92), 11.1 % (2/18), 27.1 % (13/48) and 60 % (9/15) in groups 1-6, respectively. The proportion of subjects with an ophthalmological examination within the last 12 months was highest in the groups of extremely preterm persons with and without ROP compared with the control group. Overall, 33.3 % (1/3) of the term and 57.1 % (28/49) of the preterm subjects with strabismus and 0 % (0/3) of the term and 46.9 % (15/32) of the preterm individuals with amblyopia had an ophthalmological examination within the past 12 months., Discussion: Extremely preterm adults with and without postnatal ROP showed the highest rate of eye diseases as well as the highest rate of ophthalmological check-ups within the last 12 months. This suggests that extremely preterm adults particularly with the occurrence of postnatal ROP perceive more frequent ophthalmological check-ups throughout their lives., (© 2022. The Author(s).)

Introduction: Prematurity and retinopathy of prematurity (ROP) are associated with altered corneal shape and reduced visual acuity in childhood, but their long-term effects on corneal shape in later life are still unclear. This study evaluated whether prematurity and related perinatal factors are associated with corneal aberrations in adulthood., Methods: The Gutenberg Prematurity Eye Study (GPES) is a cohort study using Scheimpflug imaging of the cornea. Associations were assessed between corneal Zernike aberrations and gestational age (GA), birth weight (BW), BW percentile, ROP occurrence, ROP treatment and other perinatal factors using univariate and multivariable linear regression analyses., Results: This study involved 444 eyes of 256 individuals born preterm (aged 28.1 ± 8.4 years, 146 females) and 231 eyes of 132 individuals born full-term (aged 29.8 ± 8.9 years, 77 females). Multivariable analyses revealed an association between corneal higher-order aberrations and lower birth weight percentile (B = -0.001, p < 0.001) as well as ROP treatment (B = 0.120, p = 0.03). Corneal lower-order aberrations were also associated with lower birth weight percentile (B = -0.004; p = 0.001) and ROP treatment (B = 0.838, p = 0.01) but not with ROP occurrence. Increased corneal aberrations were correlated with lower visual acuity and the spherical equivalent refractive error., Conclusions: Perinatal factors, particularly low birth weight percentile and ROP treatment lead to a more irregular corneal shape in adulthood, thereby reducing optical image quality and potentially contributing to reduced visual acuity and altered refractive error., (© 2022 The Authors.

Purpose: This study analyses whether prematurity, retinopathy of prematurity (ROP), and associated factors lead to altered foveal shape in adulthood and whether these alterations are associated with visual acuity., Methods: The Gutenberg Prematurity Eye Study is a German cohort study with a prospective ophthalmologic examination (participants aged 18-52 years) of individuals born preterm and full-term that were examined with spectral domain optical coherence tomography. Participants were grouped according to gestational age (GA) and postnatal ROP status. Multivariable linear regression analyses for foveolar retinal thickness, foveal hypoplasia, and posterior vitreous status were performed., Results: A total of 755 eyes of 414 preterm and full-term individuals were included (aged 28.6 ± 8.6 years, 233 female individuals). Central foveal retinal thickness increased as GA decreased. The prevalence of foveal hypoplasia was 2% (control group), 9% (GA 33-36), 18% (GA 29-32), 48% (GA ≤28), 50% (ROP without treatment), and 82% of eyes (with ROP requiring treatment). In multivariable analyses, central foveal thickness was independently associated with GA and advanced stages of ROP requiring treatment while foveal hypoplasia was only associated with GA. Posterior vitreous was more frequently visible as partially detached in full-term than in preterm individuals. Lower distant-corrected visual acuity correlated with increased foveolar thickness (rho = 0.08; P = 0.03) and with foveal hypoplasia (rho = 0.15, P < 0.001)., Conclusion: Our findings indicate that there are fetal origins affecting foveal shape, resulting in foveal hypoplasia potentially affecting the visual acuity in adulthood.
