ADHD symptoms and diagnosis in adult preterms: systematic review, IPD meta-analysis, and register-linkage study.

BACKGROUND: This study examined differences in ADHD symptoms and diagnosis between preterm and term-born adults (≥18 years), and tested if ADHD is related to gestational age, birth weight, multiple births, or neonatal complications in preterm borns. METHODS: (1) A systematic review compared ADHD symptom self-reports and diagnosis between preterm and term-born adults published in PubMed, Web of Science, and PROQUEST until April 2021; (2) a one-stage Individual Participant Data(IPD) meta-analysis (n = 1385 preterm, n = 1633 term; born 1978-1995) examined differences in self-reported ADHD symptoms[age 18-36 years]; and (3) a population-based register-linkage study of all live births in Finland (01/01/1987-31/12/1998; n = 37538 preterm, n = 691,616 term) examined ADHD diagnosis risk in adulthood (≥18 years) until 31/12/2016. RESULTS: Systematic review results were conflicting. In the IPD meta-analysis, ADHD symptoms levels were similar across groups (mean z-score difference 0.00;95% confidence interval [95% CI] -0.07, 0.07). Whereas in the register-linkage study, adults born preterm had a higher relative risk (RR) for ADHD diagnosis compared to term controls (RR = 1.26, 95% CI 1.12, 1.41, p < 0.001). Among preterms, as gestation length (RR = 0.93, 95% CI 0.89, 0.97, p < 0.001) and SD birth weight z-score (RR = 0.88, 95% CI 0.80, 0.97, p < 0.001) increased, ADHD risk decreased. CONCLUSIONS: While preterm adults may not report higher levels of ADHD symptoms, their risk of ADHD diagnosis in adulthood is higher. IMPACT: Preterm-born adults do not self-report higher levels of ADHD symptoms, yet are more likely to receive an ADHD diagnosis in adulthood compared to term-borns. Previous evidence has consisted of limited sample sizes of adults and used different methods with inconsistent findings. This study assessed adult self-reported symptoms across 8 harmonized cohorts and contrasted the findings with diagnosed ADHD in a population-based register-linkage study. Preterm-born adults may not self-report increased ADHD symptoms. However, they have a higher risk of ADHD diagnosis, warranting preventive strategies and interventions to reduce the presentation of more severe ADHD symptomatology in adulthood.

Health-Related Quality-of-Life Outcomes of Very Preterm or Very Low Birth Weight Adults: Evidence From an Individual Participant Data Meta-Analysis.

BACKGROUND AND OBJECTIVE: Assessment of health-related quality of life for individuals born very preterm and/or low birthweight (VP/VLBW) offers valuable complementary information alongside biomedical assessments. However, the impact of VP/VLBW status on health-related quality of life in adulthood is inconclusive. The objective of this study was to examine associations between VP/VLBW status and preference-based health-related quality-of-life outcomes in early adulthood. METHODS: Individual participant data were obtained from five prospective cohorts of individuals born VP/VLBW and controls contributing to the 'Research on European Children and Adults Born Preterm' Consortium. The combined dataset included over 2100 adult VP/VLBW survivors with an age range of 18-29 years. The main exposure was defined as birth before 32 weeks' gestation (VP) and/or birth weight below 1500 g (VLBW). Outcome measures included multi-attribute utility scores generated by the Health Utilities Index Mark 3 and the Short Form 6D. Data were analysed using generalised linear mixed models in a one-step approach using fixed-effects and random-effects models. RESULTS: VP/VLBW status was associated with a significant difference in the Health Utilities Index Mark 3 multi-attribute utility score of - 0.06 (95% confidence interval - 0.08, - 0.04) in comparison to birth at term or at normal birthweight; this was not replicated for the Short Form 6D. Impacted functional domains included vision, ambulation, dexterity and cognition. VP/VLBW status was not associated with poorer emotional or social functioning, or increased pain. CONCLUSIONS: VP/VLBW status is associated with lower overall health-related quality of life in early adulthood, particularly in terms of physical and cognitive functioning. Further studies that estimate the effects of VP/VLBW status on health-related quality-of-life outcomes in mid and late adulthood are needed.

Resilience in the face of peer victimization and perceived discrimination: The role of individual and familial factors.

BACKGROUND: Peer victimization and discrimination are two related forms of social victimization. However, the majority of studies only focus on one form or the other. This study investigates resilience in victims of both these forms of violence. OBJECTIVE: To identify individual and family level factors that foster, or hinder, resilience in the face of both peer victimization and perceived discrimination. PARTICIPANTS: In a sample of 2975 high-school students, 22% (n = 644) met the criteria for substantial social victimization. The sample's mean age was 16.5 years, 57% were girls, 19% were in vocational courses, 12% were from an ethnic minority background, and 5% were lesbian, gay, or bisexual. METHOD: A measure of resilience was created by regressing the mean levels of current mental health, self-esteem, and life satisfaction on the frequency of lifetime peer victimization and past year perceived discrimination. Regression analyses were conducted to identify correlates of resilience considering protective and vulnerability factors, including sociodemographic information, anxious personality, empathy, coping strategies, familial optimism, and the relationship with their mother and father. RESULTS: Resilience was associated with low anxious personality, four coping strategies (active, use of humor, low self-blame, low substance use), and satisfaction with the relationship with the mother. CONCLUSIONS: Resilience is related to both behavioral and meaning-making coping strategies, personality traits, and satisfaction in relationships. This study's findings can be used to tailor interventions to foster resilience in adolescents exposed to social victimization.

Social Functioning in Adults Born Very Preterm: Individual Participant Meta-analysis.

CONTEXT: There is a lack of research on individual perceptions of social experiences and social relationships among very preterm (VP) adults compared with term-born peers. OBJECTIVE: To investigate self-perceived social functioning in adults born VP (<32 weeks' gestation) and/or with very low birth weight (VLBW) (<1500g) compared with term-born adults (≥37 weeks' gestation) using an individual participant data (IPD) meta-analysis. DATA SOURCES: Two international consortia: Research on European Children and Adults born Preterm and Adults Born Preterm International Collaboration. STUDY SELECTION: Cohorts with outcomes assessed by using the Adult Self-Report Adaptive Functioning scales (friends, spouse/partner, family, job, and education) in both groups. DATA EXTRACTION: IPD from 5 eligible cohorts were collected. Raw-sum scores for each scale were standardized as z scores by using mean and SD of controls for each cohort. Pooled effect size was measured by difference (Δ) in means between groups. RESULTS: One-stage analyses (1285 participants) revealed significantly lower scores for relationships with friends in VP/VLBW adults compared with controls (Δ -0.37, 95% confidence interval [CI]: -0.61 to -0.13). Differences were similar after adjusting for sex, age, and socioeconomic status (Δ -0.39, 95% CI: -0.63 to -0.15) and after excluding participants with neurosensory impairment (Δ -0.34, 95% CI: -0.61 to -0.07). No significant differences were found in other domains. LIMITATIONS: Generalizability of research findings to VP survivors born in recent decades. CONCLUSIONS: VP/VLBW adults scored their relationship with friends lower but perceived their family and partner relationships, as well as work and educational experiences, as comparable to those of controls.

Very preterm birth and trajectories of domain-specific self-concept from childhood into adulthood.

Self-concept refers to individuals' perceptions of themselves in specific domains and is closely related with their overall self-esteem. Lower self-esteem has been reported in those born preterm (<37 weeks gestation), but the development of self-concept has not been studied in this population. This study investigates whether differences in trajectories of domain-specific self-concepts are explained by premature birth or other risk factors, using the Bavarian Longitudinal Study (N = 460), a population-based study of very preterm (VP; <32 weeks gestation)/very low birth weight (VLBW; <1500 g) cohort and term-born controls. Trajectories of body and social self-concept from 6 to 26 years of age were estimated using latent class growth analysis. Regression models examined the effects of VP/VLBW and other individual, social, and family factors. Two trajectories - one stable and one decreasing - were identified for both self-concepts. VP/VLBW birth was associated with decreasing self-concept in both domains, although the effect of VP/VLBW on social self-concept was weakened in the adjusted analysis. Furthermore, mediated pathways were found from VP/VLBW to decreasing social self-concept via chronic bullying (ß = 0.05, 95% CI [0.002, 0.12]) and motor impairments (ß = 0.04, 95% CI [0.01, 0.07]), suggesting that negative self-concept in the VP/VLBW population is partially modifiable through improving peer relationships and motor impairments in childhood.

Association of Very Preterm Birth or Very Low Birth Weight With Intelligence in Adulthood: An Individual Participant Data Meta-analysis.

Importance: Birth before 32 weeks' gestation (very preterm [VPT]) and birth weight below 1500 g (very low birth weight [VLBW]) have been associated with lower cognitive performance in childhood. However, there are few investigations of the association of neonatal morbidities and maternal educational levels with the adult cognitive performance of individuals born VPT or VLBW (VPT/VLBW). Objective: To assess differences in adult IQ between VPT/VLBW and term-born individuals and to examine the association of adult IQ with cohort factors, neonatal morbidities, and maternal educational level among VPT/VLBW participants. Data Sources: Systematic review of published data from PubMed and meta-analysis of individual participant data (IPD) of cohorts from 2 consortia (Research on European Children and Adults Born Preterm [RECAP] and Adults Born Preterm International Collaboration [APIC]). Study Selection: The meta-analysis included prospective longitudinal cohort studies that assessed the full-scale IQ of adults born VPT or VLBW and respective control groups comprising term-born adults. Data Extraction and Synthesis: The study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline for analyses of individual participant data and identified 8 studies that provided data from 2135 adults (1068 VPT/VLBW and 1067 term-born participants) born between 1978 and 1995. Meta-analyses of IPD were performed using a 1-stage approach, treating VPT birth or VLBW and cohort as random effects. Main Outcomes and Measures: Full-scale IQ scores were converted to z scores within each cohort using the combined SD of VPT/VLBW participants and a control group of term-born participants, with scores centered on the mean of the control group. Results: A total of 426 records were identified and screened. After exclusions, 13 studies were included in the aggregate meta-analysis. The IPD meta-analysis included 8 of the 9 RECAP and APIC cohorts with adult IQ data. The mean (SD) age among the 8 IPD cohorts was 24.6 (4.3) years, and 1163 participants (54.5%) were women. In unadjusted analyses, VPT/VLBW participants had mean adult IQ scores that were 0.78 SD (95% CI, -0.90 to -0.66 SD) lower than term-born participants, equivalent to a difference of 12 IQ points. Among VPT/VLBW participants, lower gestational age (score difference per week of gestation, 0.11; 95% CI, 0.07-0.14), lower birth weight z scores (score difference per 1.0 SD, 0.21; 95% CI, 0.14-0.28), the presence of neonatal bronchopulmonary dysplasia (score difference, -0.16; 95% CI, -0.30 to -0.02) or any grade of intraventricular hemorrhage (score difference, -0.19; 95% CI, -0.33 to -0.05), and lower maternal educational level (score difference, 0.26; 95% CI, 0.17-0.35) were all significantly associated with lower IQ scores in adulthood. Conclusions and Relevance: In this IPD meta-analysis, lower gestational age, lower weight for gestational age, neonatal morbidities, and lower maternal educational levels were all important risk factors associated with lower IQ among young adults born VPT or VLBW.

Testing the Independent and Joint Contribution of Exposure to Neurodevelopmental Adversity and Childhood Trauma to Risk of Psychotic Experiences in Adulthood.

Exposure to neurodevelopmental adversity and childhood trauma are both independently associated with psychosis. However, there is little research on the mechanism underlying their relationship with each other. The current study investigated both the independent and joint effects of neurodevelopmental adversity and childhood trauma to better understand the etiology of psychosis. A large population-based cohort (N = 3514) followed from birth was assessed on psychotic experiences (PE) at 24 years. Neurodevelopmental adversity included obstetric complications (birth weight, gestational age, in-utero influenza exposure, resuscitation) and developmental impairment (cognitive and motor impairments). Trauma exposure included caregiver and peer inflicted trauma up to 17 years. Multiple regression models tested their independent and interactive effect on PE, and path analysis estimated the indirect effect of neurodevelopmental adversity on PE via trauma. Neurodevelopmental adversity (OR = 1.32, 95%CI: 1.08-1.62) and trauma (OR = 1.97, 95%CI: 1.65-2.36) independently increased the odds of PE. There was also an indirect relationship between neurodevelopmental adversity and PE via increased exposure to childhood trauma (ß = 0.01, 95%CI: 0.004-0.024). In particular, peer bullying mediated the association between developmental impairment to PE (ß = 0.02, 95%CI: 0.01-0.03). In conclusion, children with neurodevelopmental adversity, in particular those with developmental impairment, are more likely to be exposed to trauma. This new etiological understanding of psychosis suggests that PE may be partially modifiable through reducing exposure to peer bullying, especially in children with developmental impairment.

Testing the neurodevelopmental, trauma and developmental risk factor models of psychosis using a naturalistic experiment.

BACKGROUND: The neurodevelopmental and trauma theories are two widely cited models of psychosis. A third - the developmental risk factor model (DRFM) - recognises the combined role of neurodevelopmental risks and trauma. Our objective was to test these theories using preterm populations as a natural experiment, given the high prevalence of neurodevelopmental deficits and exposure to trauma. METHODS: Two population-based preterm birth cohorts, the Bavarian Longitudinal Study (BLS; N = 399) and EPICure Study (N = 184), were included with term-born controls. Peer victimisation in childhood was assessed by parent and child report and psychotic experiences (PE) were assessed in early adulthood. Different models of psychosis were tested using regression and mediation analyses. RESULTS: There was support for the trauma and DRFM in the BLS. Peer victimisation increased the risk of PE for preterm and term-born participants equally [odds ratio = 4.87, 95% confidence interval (CI) 1.96-12.08]. There was an indirect effect where preterm children were more likely to be victimised, which subsequently increased risk of PE [ß = 1.12 (s.e. = 0.61), 95% CI 0.11-2.48]. The results were replicated in EPICure. CONCLUSIONS: Exposure to trauma which is experienced more often by neurodevelopmental risk children rather than neurodevelopmental risk per se increases the risk of PE. The findings are consistent with the trauma model and DRFM. Interventions focused on reducing trauma may reduce the development of PE.

The distribution of Cteniloricaria (Siluriformes: Loricariidae): known and new records in Brazil suggest headwater captures as drivers of disjoint distribution

Cteniloricaria is a genus of Neotropical armored catfishes belonging to the Loricariinae, currently including two valid species: C. platystoma and C. napova. Cteniloricaria platystoma is presently recorded across the main coastal drainages of the Guiana Shield, from the Sinnamary River, French Guiana, to the Essequibo River basin, Guyana, and is considered to be restricted to the region. Cteniloricaria napova is only known from its type locality at the headwaters of the Paru de Oeste River, Amazon basin, Sipaliwini Savannah, Trio Amerindian territory in Suriname, close to the Brazilian border. Based on a specimen of C. napova, captured in the Cuminapanema River, a tributary to the Curuá River, within Brazilian territory, the geographic distribution of the species and the genus is extended, representing the first record of Cteniloricaria in Brazil. The genus shows a disjoint distribution, and divergence between populations in the north-flowing coastal rivers of the Guianas and the south-flowing Amazon tributaries, and more recent headwater capture between south-flowing Amazon tributaries, may have played a key role in shaping its current distribution. Illustrations, diagnostic characters, morphometrics, description of the habitat where the new specimen was captured, extinction risk assessment, and a discussion of the distribution of the genus are provided.(AU)

Cteniloricaria é um gênero de cascudos neotropicais pertencente à Loricariinae, atualmente incluindo duas espécies válidas: C. platystoma e C. napova. Atualmente, C. platystoma é registrada nas principais drenagens costeiras do Escudo das Guianas, desde o rio Sinnamary, na Guiana Francesa, até a bacia do rio Essequibo, Guyana, sendo considerada restrita à região. Cteniloricaria napova é conhecida unicamente por sua localidade-tipo nas cabeceiras do rio Paru de Oeste, bacia Amazônica, Savana Sipaliwini, território indígena de Trio, no Suriname, próximo à fronteira com o Brasil. Com base em um espécime de C. napova, capturado no rio Cuminapanema, afluente do rio Curuá, em território brasileiro, a distribuição geográfica da espécie e do gênero se estende até a bacia do rio Curuá, representando o primeiro registro de Cteniloricaria no Brasil. O gênero apresenta uma distribuição disjunta e, eventos como divergência entre as populações dos rios costeiros das Guianas e nos afluentes do Amazonas, e mais recente captura de cabeceiras entre os afluentes do Amazonas, podem ter desempenhado um papel fundamental em sua distribuição atual. São fornecidos ilustrações, caracteres diagnósticos, morfometria, descrição do habitat onde o novo espécime foi capturado, avaliação do risco de extinção e uma discussão sobre a distribuição do gênero.(AU)

The Role of Executive and General Cognitive Functioning in the Attention Problems of Very and Extremely Preterm Adults.

OBJECTIVE: To determine whether the attention problems in adults born very preterm/very low birth weight (VP/VLBW; <32 weeks' gestation/<1500 g) or extremely preterm (EP; <26 weeks' gestation) are associated with specific executive or general cognitive deficits. METHOD: Cohorts of VP/VLBW (the Bavarian Longitudinal Study [BLS]) and EP (the EPICure Study) participants were followed from birth to early adulthood, each also following a respective control group. Adult attention deficit hyperactivity disorder (ADHD) symptoms were assessed via self-report in both cohorts and additionally by parent report in the BLS. Participants in both cohorts also had their attention span rated by trained observers. Performed separately in each cohort, hierarchical regression analyses were used to assess whether the association between preterm birth status and attention problems remained after accounting for executive functioning (inhibitory control and working memory) in adulthood, childhood intelligence score (IQ), or sex. RESULTS: In the discovery cohort of the BLS, significant differences were found between VP/VLBW adults and controls for parent-rated inattention (p < 0.001). However, for self-reported measures of ADHD, no significant differences were found in the BLS or in the EPICure replication cohort. In both cohorts, observer-rated attention spans were lower for VP/VLBW and EP participants in comparison to their respective control groups (p < 0.001). In final models for the BLS, inhibitory control and childhood IQ were significantly associated with parent-rated inattention symptoms (p < 0.006), whereas working memory and childhood IQ were significantly associated with observer-rated attention span (p < 0.001). The effect of childhood IQ on observer-rated attention span was replicated in EPICure. CONCLUSION: VP/VLBW and EP adults are at increased risk of observer-rated attention problems. These problems were predominantly associated with poorer general cognitive ability in early childhood and somewhat with adult executive functioning.

Rapid assessment of the ichthyofauna of the southern Guiana Shield tributaries of the Amazonas River in Pará, Brazil

The Northern Pará Drainage System encompasses the left-bank tributaries of the Amazonas River in the southern Guiana Shield region of Pará state, Brazil. Five of the region's state protected areas are considered strategic for the conservation of its biodiversity. In the present study, we assessed the ichthyofauna of the five state protected areas of the Northern Pará Drainage System. Seven expeditions were conducted between January 2008 and January 2009, which surveyed stretches of the Cuminá, Cuminapanema, Curuá, Jari, Mapuera, Nhamundá, and Paru rivers. These surveys yielded 286 species belonging to 38 families and eight orders, including seven new records of fish species for Brazil, six of which are also new records for the Amazon basin. Our results provide a valuable database for future research and conservation programs in the protected areas of the region. (AU)

Association of sport participation in preterm and full term born children and body and fat mass indices from age 3 to 14 years.

OBJECTIVES: To assess the association of gestational age groups (VP: <32 weeks, MP: 32-33 weeks, LP: 34-36 weeks and FT: ≥37 weeks of gestation) and club sport participation in childhood on body mass index (BMI), fat free mass index (FFMI) and fat mass index (FMI). DESIGN: Longitudinal, cross sectional. METHODS: BMI (age 3, 5, 7, 11 and 14 years; N=10581-14702) and FFMI/FMI (age 7, 11 and 14 years; N=10446-12996) and consistent club sport participation at age 5, 7 and 11 years (ranging from never participating to participating at all three ages) were assessed prospectively. These were compared by gestational age and their associations with BMI and FMI were investigated, while controlling for confounders (socio-economic, maternal obesity, child related, diet). RESULTS: BMI and FFMI was lower in VP or MP until age 7, but no differences were found in BMI, FFMI or FMI after age 11 with regard to gestational age. Consistent club sport participation from age 5-11 was unrelated to BMI at ages 3-7. However, FT children with club sport participation had lower BMI and FMI at ages 11 and 14; but this association was not found in VP or MP. CONCLUSIONS: During adolescence body composition of VP and MP become similar to FT born peers. Consistent sport participation reduces BMI and FMI in FT only. In VP or MP children modifying effects of sport on body composition might not be detected due to the catch-up growth in weight, height and fat mass at the same time.

Association of Preterm Birth and Low Birth Weight With Romantic Partnership, Sexual Intercourse, and Parenthood in Adulthood: A Systematic Review and Meta-analysis.

Importance: Social relationships are important determinants of well-being, health, and quality of life. There are conflicting findings regarding the association between preterm birth or low birth weight and experiences of social relationships in adulthood. Objective: To systematically investigate the association between preterm birth or low birth weight and social outcomes in adulthood. Data Sources: PubMed, PsycINFO, Web of Science, and Embase were searched for peer-reviewed articles published through August 5, 2018. Study Selection: Prospective longitudinal and registry studies reporting on selected social outcomes in adults who were born preterm or with low birth weight (mean sample age ≥18 years) compared with control individuals born at term. Data Extraction and Synthesis: The meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The data were collected and extracted by 2 independent reviewers. Pooled analyses were based on odds ratios (ORs) with 95% confidence intervals and Hedges g, which were meta-analyzed using random-effects models. Main Outcomes and Measures: Ever being in a romantic partnership, ever having experienced sexual intercourse, parenthood, quality of romantic relationship, and peer social support. Results: Twenty-one studies were included of the 1829 articles screened. Summary data describing a maximum of 4 423 798 adult participants (179 724 preterm or low birth weight) were analyzed. Adults born preterm or with low birth weight were less likely to have ever experienced a romantic partnership (OR, 0.72; 95% CI, 0.64-0.81), to have had sexual intercourse (OR, 0.43; 95% CI, 0.31-0.61), or to have become parents (OR, 0.77; 95% CI, 0.65-0.91) than adults born full-term. A dose-response association according to degree of prematurity was found for romantic partnership and parenthood. Overall, effect sizes did not differ with age and sex. When adults born preterm or with low birth weight were in a romantic partnership or had friends, the quality of these relationships was not poorer compared with adults born full-term. Conclusions and Relevance: These findings suggest that adults born preterm or with low birth weight are less likely to experience a romantic partnership, sexual intercourse, or to become parents. However, preterm birth or low birth weight does not seem to impair the quality of relationships with partners and friends. Lack of sexual or partner relationships might increase the risk of decreased well-being and poorer physical and mental health.

Prospective Study of Physical Activity of Preterm Born Children from Age 5 to 14 Years.

OBJECTIVE: To investigate whether level of prematurity (very, moderate, late preterm, vs full term) is associated with physical activity from childhood to adolescence and to identify factors in childhood that predict moderate-vigorous physical activity in early adolescence. STUDY DESIGN: Parents reported on physical activity at the age 5, 7, and 11 years (n = 12 222-14 639) and adolescents self-reported on moderate-vigorous physical activity at 14 years (n = 10 974). At age 14 years, a subgroup was also assessed by wrist accelerometer (n = 4046). RESULTS: Prematurity was associated with a small or no difference in physical activity at each time point. At age 14 years, moderate-vigorous physical activity in self-report and accelerometer was higher in male adolescents, those of white ethnicity, or higher parental education, having been taken to live sport events at age 5 or 7 years or having taken part in organized physical activity at 5 or 7 years. CONCLUSIONS: In this representative national cohort study in the United Kingdom, preterm birth was not found to be associated with physical activity between 5 and 14 years. Organized physical activity and watching sport events early in life may increase moderate to vigorous physical activity in adolescents.

Association of physical activity and cardiorespiratory function or BMI and body composition in preterm-born individuals: a systematic review.

AIM: To evaluate the association of physical activity (PA) and forced expiratory volume in one second (FEV1), peak oxygen consumption (pVO2), body mass index (BMI) and body composition in preterm-born individuals. METHODS: Cochrane Library, EMBASE, MEDLINE, AMED, ERIC, Web of Science and PsycInfo were searched with no restriction on language and date of publication from inception to January 2018. Data were extracted comparing preterm-born individuals with different frequencies of PA and the outcome of interest. RESULTS: One randomized controlled, two longitudinal and thirteen cross-sectional studies comprising 1922 preterm-born individuals aged 5-25 were included. Assessment varied from a PA program to accelerometer data, interviews and self-report questionnaires. In preterm-born children, more PA was associated with better cardiorespiratory function in those groups with impaired lung function or with lower BMI in those groups with increased risk factors, but no association was found in unimpaired children. In preterm-born adults, more PA was associated with higher pVO2 and lower BMI. CONCLUSION: Only tentative conclusions can be drawn, especially regarding differences of the association of PA between preterm- and term-born populations. Further studies are needed to analyse the association of PA in preterm-born individuals with reduced cardiorespiratory function.

A new species of Ituglanis Costa Bockmann, 1993 (Siluriformes: Trichomycteridae) from Rio Ribeira de Iguape and upper Rio Tietê basins, southeastern Brazil.

Ituglanis amphipotamus, new species, is distinguished from all congeners by the combination of the following characters: anterior cranial fontanel present, i,5 pectoral-fin rays, nasal canal and antorbital segment of infraorbital canal absent, five or six pairs of ribs, 39 post-Weberian vertebrae. It can be further distinguished from the sympatric I. proops by the size of the interopercular patch of odontodes. The new species is described from the Rio Ribeira de Iguape and the upper Rio Tietê basins in the southeastern region of Brazil. Comments on the biogeography of the new taxa and putative relationships with its congeners are presented. [Zoobank: urn:lsid:zoobank.org:act:AC2F3365-92C0-4444-AC89-9546365158EC].

Preterm Birth/Low Birth Weight and Markers Reflective of Wealth in Adulthood: A Meta-analysis.

CONTEXT: Preterm birth and/or low birth weight (PT/LBW) increases the risk of cognitive deficits, which suggests an association between PT/LBW and lower wealth in adulthood. Nevertheless, studies have revealed inconsistent findings so far. OBJECTIVE: To systematically investigate whether PT/LBW is associated with markers of adulthood wealth. DATA SOURCES: We searched Medline, PubMed, PsycINFO, Web of Science, and Embase. STUDY SELECTION: Prospective longitudinal and registry studies containing reports on selected wealth-related outcomes in PT/LBW-born adults compared with term-born controls. DATA EXTRACTION: Two independent reviewers extracted data on educational qualifications, employment rates, social benefits, and independent living. RESULTS: Of 1347 articles screened, 23 studies met the inclusion criteria. PT/LBW was associated with decreased likelihood of attainment of higher education qualifications (odds ratio [OR] = 0.74; 95% confidence interval [CI] = 0.69-0.80), lower employment rate (OR = 0.83; 95% CI = 0.74-0.92), and increased likelihood of receiving social benefits (OR = 1.25; 95% CI = 1.09-1.42). A dose-response relationship according to gestational age was only found for education qualifications. PT/LBW-born adults did not differ significantly from those born at term in independent living. LIMITATIONS: There was high heterogeneity between studies. There were unequal numbers of studies from different regions in the world. CONCLUSIONS: PT/LBW is associated with lower educational qualifications, decreased rate of employment, and an increased rate of receipt of social benefits in adulthood. Low educational qualifications were most prevalent in those born very preterm and consistent across geographic regions. However, the findings are less clear for independent living.

Lifecourse transitions, gender and drinking in later life.

Older people consume less alcohol than any other adult age group. However, in recent years survey data on alcohol consumption in the United Kingdom have shown that while younger age groups have experienced a decline in alcohol consumption, drinking behaviours among the elderly have not reduced in the same way. This paper uses data from the English Longitudinal Study of Ageing to analyse both the frequency and quantity of older adult's alcohol consumption using a lifecourse approach over a ten-year period. Overall drinking declined over time and the analysis examined how socio-economic characteristics, partnership, employment and health statuses were associated with differences in drinking behaviours and how these changed over time. Higher wealth and level of education were associated with drinking more and drinking more frequently for men and women. Poorer self-rated health was associated with less frequent consumption and older people with poor and deteriorating health reported a steeper decline in the frequency of alcohol consumption over time. Men who were not in a partnership drank more than other men. For women, loss of a partner was associated with a steeper decline in drinking behaviours. These findings have implications for programmes to promote responsible drinking among older adults as they suggest that, for the most part, characteristics associated with sustaining wellbeing in later life are also linked to consuming more alcohol.
