OBJECTIVE: To determine the risk for psychiatric disorders among extremely low birth weight (ELBW) survivors in their early to mid-30s and to determine whether those born small for gestational age or those exposed to a full course of antenatal corticosteroids (ACS) were at particularly high risk. METHODS: A prospective, longitudinal, population-based cohort of 84 ELBW survivors and 90 normal birth weight (NBW) control participants born in Ontario, Canada from 1977 to 1982 were assessed by interviewers naive to birth weight status using the Mini-International Neuropsychiatric Interview. RESULTS: ELBW survivors had lower odds of an alcohol or substance use disorder but higher odds of current non-substance-related psychiatric problems (odds ratio [OR] = 2.47; 95% confidence interval [CI], 1.19-5.14). Those born ELBW and SGA exhibited the same patterns with larger effects. ACS-exposed ELBW survivors had even higher odds of any current non-substance-related psychiatric disorder (OR = 4.41; 95% CI, 1.65-11.82), particularly generalized anxiety disorder (OR = 3.42; 95% CI, 1.06-11.06), the generalized type of social phobia (OR = 5.80; 95% CI, 1.20-27.99), and the inattentive subtype of attention-deficit/hyperactivity disorder (OR = 11.45; 95% CI, 2.06-63.50). CONCLUSIONS: In their early to mid-30s, ELBW survivors were less likely to have alcohol or substance use disorders but may be at greater risk for other psychiatric problems. Those exposed to ACS were at especially high risk and manifested no reduction in alcohol or substance use disorders. ELBW survivors exposed to ACS may be a special group at risk for psychopathology in adulthood. [ABSTRACT FROM AUTHOR]

Abstract. Chronic childhood illness, disability, and psychosocial problems are receiving major attention in current pediatric care. Much of the evidence associating chronic physical problems and mental health and adjustment problems has come from clinic-based studies and is often inconsistent in its conclusions. This paper reports the findings of the Ontario Child Health Study, an epidemiologic survey of 3,294 children 4 to 16 years of age in the general community, concerning the relationship of psychiatric disorders and social adjustment problems among children with chronic illness, medical conditions, and long-term disability in contrast to children free of chronic physical health problems. Age- and sex-adjusted risks for psychiatric disorders and social problems, compared with those for healthy peers, were calculated: children with both chronic illness and associated disability were at greater than threefold risk for psychiatric disorders and considerable risk for social adjustment problems. Children with chronic medical conditions, but no disability, were at considerably less risk: about a twofold increase in psychiatric disorders but little increased risk for social adjustment problems was observed. A relative underuse of specialized mental health services by children who might benefit supports the opinion that all physicians in the community who care for children with chronic health problems should become skilled in the recognition of existing or incipient mental health and social problems and familiar with preventive and treatment approaches that may lessen the excessive burden of psychosocial problems among those with chronic ill-health.

Abstract. Ail very low-birth-weight infants live-born to residents of an urban southern Ontario county were studied before (1964 to 1969) and after (1973 to 1977) the introduction of neonatal intensive care. Mortality at hospital discharge decreased from 89.4% to 77.6% kraong infants whose birth weights were 500 to 999 gm and from 37.6% to 22.8% among infants with birth weights of 1,000 to 1,499 gm. The families of 121/150 (81%) and 134/151 (89%) of all children from the two cohorts who were discharged from the hospital alive were surveyed. At follow-up 7/121 (6%) and 4/134 (4%) had died. Major damage was reported for 13/121 (11%) and 18/134 (13%) of the children. Neonatal intensive care was associated with a significant reduction in mortality but there has not been a significant change in morbidity. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To determine: (1) if childhood cognitive and academic abilities mediate the association between being born at extremely low birth weight (ELBW) and socioeconomic attainment at age 29 to 36 years; (2) which cognitive abilities (IQ, verbal abilities, fluid intelligence, mathematical abilities, or academic achievement) most strongly mediate this association; and (3) if the mediating role of cognition is different in ELBW survivors with significant neurosensory impairment (NSI). METHODS: A prospective, longitudinal cohort of 100 Canadian ELBW survivors born between 1977 and 1982 and 89 normal birth weight comparison participants were used to examine the mediating role of childhood cognition by using 5 cognitive mediators assessed at age 8 years (overall IQ, verbal IQ, performance IQ, quantitative ability, and academic achievement) on socioeconomic attainment at adulthood. Socioeconomic attainment was defined as personal annual earnings and full-time employment assessed via self-report at age 29 to 36 years. RESULTS: Mediation models revealed that childhood cognition mediated the association between ELBW status and income attainment, with mathematical abilities and overall IQ each accounting for 26% of the direct effect. Mediated effects were not statistically significant in full-time employment models. For both outcomes, the mediating effect of cognition was stronger for ELBW survivors with NSI. CONCLUSIONS: Childhood cognitive abilities partially mediate associations between ELBW status and adult income attainment. Early life cognition is a critical predictor of socioeconomic attainment in ELBW survivors, particularly in those born with NSI. Interventions aimed at enhancing early cognition in ELBW survivors may help optimize their later socioeconomic attainment. [ABSTRACT FROM AUTHOR]

Abstract. This paper presents the results of an epidemiologic study that compares and contrasts psychosocial characteristics of parents and family units of children with chronic illness or physical disability (chronic health problems) with those of healthy children. Data were derived from the Ontario Child Health Study of 1869 randomly selected families, with 3294 children aged 4 to 16 years. In the absence of significant differences between parents and families of children with chronic illness alone and those with physical disability, these groups were combined for analysis, for which odds ratios (OR) or t tests were used. Significant positive findings included increased rates of parental treatment for "nerves" (mothers' OR = 2.1, fathers' OR = 1.9) and increased maternal negative affect scores (Bradburn Affect Balance Scale) (P < .001) among parents of children with chronic health problems. Important negative findings (95% confidence interval of the OR included 1) included no increase in single-parent families (OR = 1.2), social isolation (OR = 1.0), or alcohol problems (OR = 1.2) among parents of children with chronic health problems. Categorically defined family dysfunction did not differ between the two groups (OR = 1.1). These data contrast with several clinic-based studies and suggest that, in a widely generalizable population survey, families of children with chronic health problems including physical disability do not suffer a marked excess of dysfunction, although some indicators of individual parent psychosocial problems were modestly elevated. It is concluded that clinicians working with children with chronic health problems should always assess psychosocial well-being. They must, however, be careful to avoid expectation bias or...

BACKGROUND: Young adults born with extreme prematurity have increased blood pressure and insulin resistance. This study documents their metabolic health as they enter their fourth decade of life. The study objective was to compare body composition, glycemia, lipid levels, and blood pressure in adults born with extremely low birth weight (ELBW) versus age- and sex- matched normal birth weight (NBW) control subjects and to examine related previous and current exposures. METHODS: The study examines one of the oldest regionally representative cohorts of ELBW subjects (birth weight <1 kg) and NBW individuals born between 1977 and 1982. The primary outcome was dysglycemia (type 2 diabetes or prediabetes) based on results of a 75-g oral glucose tolerance test. Secondary outcomes include body composition, insulin resistance, fasting lipid profile, and blood pressure. Potential predictive factors included birth weight, maternal antenatal corticosteroid exposure, retinopathy of prematurity, growth parameters, and smoking history. RESULTS: Adults (mean age, 31.8 years) born ELBW (n = 100) had a higher percent body fat (P = .004) and lower lean mass for height (P = .018) but similar waist circumference (P = .54) and BMI (P = .61) compared with NBW control subjects. ELBW adults had a 4.0-fold (95% confidence interval, 1.53-10.66) increased risk of developing dysglycemia. Adults born ELBW also had higher systolic (P = .004) and diastolic (P = .02) blood pressures compared with NBW control subjects, but there were no differences in lipid profile. CONCLUSIONS: By their fourth decade, these adults born extremely premature had increased body fat, lower lean mass, and a 4-fold increased risk of developing dysglycemia. [ABSTRACT FROM AUTHOR]

An abstract of the article "Economic Outcomes in Young Adulthood for Extremely Low Birth Weight Survivors," by John H. Goddeeris and colleagues is presented.

ABSTRACT. Background. We have previously shown that infants who were extremely low birth weight (ELBW) are particularly vulnerable to problems related to inattention and hyperactivity at school age. It is not known whether these problems persist to adolescence. Objective. To explore and compare the levels of psychopathology in a regional cohort of ELBW infants and sociodemographically matched term controls as reported by teens and their parents. Design/Methods. Cross-sectional cohort study/geographically defined region. Participants. Teens: ELBW 141/169 (83%) and control 122/145 (84%), aged 12 to 16 years. Parents: ELBW 143/169 (85%) and control 123/145 (85%). Both cohorts and their parents completed the Ontario Child Health Study-Revised questionnaire with 6 behavioral subsca1es: conduct disorder, oppositional defiant disorder, attention-deficit/ hyperactivity disorder (ADHD), overanxious, separation anxiety, and depression. Results. By teen self-report, there were no significant differences between ELBW and control teens on any of the 6 subscale scores. However, parents of ELBW teens reported significantly higher scores than parents of control for depression and ADHD based on 2-way analysis of variance (group x gender). Comparison within teen/ parent dyads showed that both cohorts of teens reported significantly higher scores than their parents. Multivariable analyses on behavioral subscale scores demonstrated a number of variables that were significant predictors by parent report: group (ELBW vs control), gender, family function, developmental quotient, maternal mood, and socioeconomic status; no predictors were significant by teen report. There were no statistically significant interaction effects for any of the models. These models explained a greater percent of the variance in behavioral scores for parents than for teens (12.5%-22.0% vs 3.4%-8.2%). Results were similar when teens with neurosensory impairment were excluded. Conclusions. This study is... [ABSTRACT FROM AUTHOR]

BACKGROUND: While children born at extremely low birth weight (ELBW; <1000 g) are at elevated risk for peer victimization, no research has examined its effects on mental health in adulthood. METHODS: ELBW survivors and matched normal birth weight (NBW; >2500 g] controls were part of a prospective, population-based study in Ontario, Canada. Peer victimization before age 16 was self-reported at age 22 to 26 years by using a 10-point measure. Presence of psychiatric disorders was examined at age 22 to 26 years (ELBW n = 142, NBW n = 133) and age 29 to 36 years (ELBW n = 84, NBW n = 90). RESULTS: After adjustment for confounding variables, for each 1-point increase in the peer victimization score, ELBW survivors had increased odds of current depressive (odds ratio [OR] = 1.67, 95% confidence interval [CI], 1.23-2.28), anxiety (OR = 1.36, 95% CI, 1.05-1.76), avoidant (OR = 1.39, 95% CI, 1.08-1.79), antisocial (OR = 1.92, 95% CI, 1.06-2.87), and attention-deficit/hyperactivity (OR = 1.39, 95% CI, 1.06-1.83) problems at age 22 to 26 years. At age 29 to 36 years, peer victimization score predicted increased odds of current panic disorder (OR = 1.69, 95% CI, 1.01-2.83) and obsessive-compulsive disorder (OR = 3.56, 95% CI, 1.25-10.09). For NBW controls, peer victimization predicted increased odds of antisocial problems at age 22 to 26 years. CONCLUSIONS: ELBW survivors and NBW participants are vulnerable to the adverse psychiatric effects of childhood peer victimization in adulthood. [ABSTRACT FROM AUTHOR]
