RESUMO
OBJECTIVES: To test whether preschool academic skills were associated with educational attainment in adolescence and whether associations differed between individuals born preterm and at full term. STUDY DESIGN: This prospective cohort study comprised 6924 individuals, including n = 444 (6.4%) adolescents born preterm (<37 weeks of gestation) from the Avon Longitudinal Study of Parents and Children. Preschool academic (mathematics and literacy) skills were rated by teachers at 4-5 years. Educational attainment at 16 years was informed by attaining a General Certificate of Secondary Education (GCSE) in key subjects mathematics and English. Logistic regressions assessed the association between preterm birth, preschool mathematics, and GCSE Mathematics and between preterm birth, preschool literacy, and GCSE English. RESULTS: Similar numbers of adolescents born preterm and at term achieved a GCSE in mathematics and English (53.6 % vs 57.4% and 59.5% vs 63.9%, respectively; P values > .05). Higher preschool academic skill scores in mathematics were associated with greater odds of attaining GCSE Mathematics and preschool literacy skills were associated with GCSE English. Adolescents born preterm with higher preschool mathematics (OR: 1.51, CI: 1.14, 2.00) and literacy skills (OR: 1.57, CI: 1.10, 2.25) were more likely to attain GCSEs in the respective subject than their term-born counterparts with equal levels of preschool skills. CONCLUSIONS: Preschool academic skills in mathematics and literacy are associated with educational attainment of preterm and term-born individuals in adolescence. Children born prematurely may benefit more from preschool mathematics and literacy skills for academic and educational success into adolescence than term-born individuals.

This study examined whether maternal warmth in early childhood moderates the association between preterm birth and problems in peer relationships and low engagement in romantic relationships in adolescence. We studied 9193 individuals from the Millennium Cohort Study in the United Kingdom, 99 (1.1%) of whom were born very preterm (VPT; < 32 weeks of gestation) and 629 (6.8%) moderate-to-late preterm (MLPT; 32-36 weeks gestation). Maternal warmth was reported by the mothers when their children were 3 years old. Peer relationship problems were reported by both the participants and their mothers at 14 and 17 years. Further, participants reported their engagement in romantic relationships at 14 and 17 years. All outcome variables were z-standardized, and the moderation effect was examined via hierarchical linear regressions. Compared to full-term birth, both MLPT and VPT birth were associated with lower engagement in romantic relationships at 17 years of age (b = .04, p = .02; b = .11, p = .02, respectively), and VPT birth was associated with increased peer relationship problems at 14 (b = .29, p = .01) and 17 years of age (b = .22, p = .046). Maternal warmth in early childhood was similarly associated with lower peer relationship problems in MLPT, VPT and full-term born adolescents. However, there was no influence of maternal warmth on engagement in romantic relationships at 17 years of age. There is no major modifying effect of maternal warmth in early childhood on the association between PT birth and peer relationship problems and low engagement in romantic relationships at 14 and 17 years of ages.
RESUMO
The aim of the current study was to examine whether self-control skills in childhood moderate the association between very preterm birth (<32 weeks of gestational age) and emotional problems and peer victimization in adolescence. We used data from four prospective cohort studies, which included 29,378 participants in total (N = 645 very preterm; N = 28,733 full-term). Self-control was mother-reported in childhood at 5-11 years whereas emotional problems and peer victimization were both self- and mother-reported at 12-17 years of age. Findings of individual participant data meta-analysis showed that self-control skills in childhood do not moderate the association between very preterm birth and adolescence emotional problems and peer victimization. It was shown that higher self-control skills in childhood predict lower emotional problems and peer victimization in adolescence similarly in very preterm and full-term borns.
RESUMO
OBJECTIVE: To study self-reported well-being and self-esteem among adolescents born very preterm (VPT; <32 wk of gestation) and moderate to late preterm (MLPT; 32-36 wk of gestation) compared with those born full-term (FT) in an individual participant data (IPD) meta-analysis. METHODS: We obtained IPD from the following 4 data sources: The Avon Longitudinal Study of Parents and Children (United Kingdom), the Millennium Cohort Study (United Kingdom), the Basel Study of Preterm Children (Switzerland), and the Bavarian Longitudinal Study (Germany) and conducted two-step random-effects IPD meta-analysis. A total of 986 MLPT, 412 VPT, and 12,719 FT born adolescents reported on subjective well-being and 927 MLPT, 175 VPT, and 13,312 FT born adolescents reported on global self-esteem. RESULTS: Adolescents born VPT or MLPT were not different from those born FT regarding general subjective well-being; family, school, and physical appearance-related well-being; and global self-esteem. However, adolescents born VPT reported lower well-being in peer relationships than those born FT (ß = -0.209, 95% confidence interval = -0.336 to -0.082). There was no main effect of fetal growth restriction (FGR) and no moderation by FGR, sex, parental education, and ethnicity. No significant heterogeneity between cohorts was found, although some heterogeneity estimates were moderate. CONCLUSION: Adolescents born preterm mostly report no lower well-being and self-esteem than adolescents born FT. However, they perceive their peer relationships as poorer than those born FT.

Background: Preterm birth is a risk factor for the development of emotional and behavioural problems in childhood and adolescence. Given the substantial improvements in neonatal care across decades, it has been expected that the difference in emotional problems, hyperactivity, and conduct problems between moderate to late preterm (MLPT) and full term (FT) children and adolescents have declined in recent years. Methods: Data from four UK population-based studies were used: The National Child Development Study (NCDS; 1958), the British Cohort Study (BCS70; 1970), the Avon Longitudinal Study of Parents and Children (ALSPAC, 1991-1992) and the Millennium Cohort Study (MCS; 2000-2002). Emotional problems, hyperactivity and conduct problems were assessed with mother-reports in early childhood (5-7 years), late childhood (10-11 years) and adolescence (14-16 years). Furthermore, emotional problems were self-reported in adolescence in BCS70, ALSPAC and MCS. Results: In the most recent cohort, the MLPT group had higher mother-reported emotional problems than those born FT in late childhood and adolescence, whereas there were no differences in self-reported emotional problems in adolescence. Regarding mother-reported hyperactivity symptoms, the MLPT group had higher scores than the FT group in the two most recent cohorts in late childhood and in the most recent cohort in adolescence. Regarding mother-reported conduct problems, MLPT children had significantly higher scores than the FT children in the oldest and in the most recent cohort in late childhood. On the other hand, in adolescence, MLPT children had significantly lower scores in conduct problems in comparison to FT children in the cohort born in 1991-1992. Conclusions: Mother-reported emotional problems and hyperactivity symptoms of those born MLPT have increased from the birth years 1958 to 2000-2002 during late childhood and adolescence, whereas self-reported emotional problems were similar in MLPT and FT groups during adolescence from 1970 to 2000-2002. Findings are less consistent regarding conduct problems. The current findings highlight the importance of raising the awareness of teachers about the association between MLPT birth and behavioural and emotional problems in late childhood and adolescence to prevent the long-term negative outcomes associated with the sequalae of MLPT birth.
RESUMO
This study examined whether physical activity is associated with better mental health and well-being among very preterm (≤32 weeks) and term born (≥37 weeks) adolescents alike or whether the associations are stronger in either of the groups. Physical activity was measured with accelerometry in children born very preterm and at term in two cohorts, the Basel Study of Preterm Children (BSPC; 40 adolescents born ≤32 weeks of gestation and 59 term born controls aged 12.3 years) and the Millennium Cohort Study (MCS; 45 adolescents born ≤32 weeks of gestation and 3137 term born controls aged 14.2 years on average). In both cohorts, emotional and behavioral problems were mother-reported using the Strengths and Difficulties Questionnaire. Subjective well-being was self-reported using the Kidscreen-52 Questionnaire in the BSPC and single items in the MCS. Hierarchical regressions with 'preterm status × physical activity'-interaction effects were subjected to individual participant data (IPD) meta-analysis. IPD meta-analysis showed that higher levels of physical activity were associated with lower levels of peer problems, and higher levels of psychological well-being, better self-perception/body image, and school related well-being. Overall, the effect-sizes were small and the associations did not differ significantly between very preterm and term born adolescents. Future research may examine the mechanisms behind effects of physical activity on mental health and wellbeing in adolescence as well as which type of physical activity might be most beneficial for term and preterm born children.
