Childhood trauma, adolescent risk behaviours and cardiovascular health indices in the 2004 Pelotas Birth Cohort / Megan BAILEY in Journal of Child Psychology and Psychiatry, 66-11 (November 2025)

However, there has been little longitudinal research exploring these associations in adolescence, especially in low- and middle-income countries (LMICs). To address this, we investigated longitudinal pathways from trauma to risk behaviours and cardiovascular health indices among adolescents in the 2004 Pelotas Birth Cohort, Brazil. Methods Lifetime cumulative trauma was assessed via caregiver reports up to age 11, and combined adolescent/caregiver reports at ages 15 and 18. At age 18, current problematic alcohol use, smoking, illicit drug use and sleep duration were measured via self-report and resting heart rate (HR) and blood pressure (BP) were assessed. We tested for trauma risk behaviour?HR/BP associations using multivariable regression, population attributable fractions and counterfactual mediation. Results Of 4,229 adolescents (51.9% boys), 81.9% were trauma-exposed by age 18. Cumulative trauma up to ages 15 and 18 increased the odds of age 18 alcohol, smoking and drug use (adjusted ORs: 1.25?1.44). Sleep duration was unrelated to childhood trauma. Population attributable fractions indicated that childhood trauma explained ≥28% of age 18 substance use. Unexpectedly, greater trauma exposure was associated with lower resting HR and BP. Substance use partially mediated the effect of trauma on cardiovascular health indices. Conclusions Trauma is associated with substance use in LMIC adolescents. Prevention and intervention strategies targeting trauma are critical given this significant burden. Our finding that trauma predicts lower HR/BP warrants further exploration given well-established associations between trauma and poorer cardiovascular health in adulthood.

Increase in child behavior problems among urban Brazilian 4-year olds: 1993 and 2004 Pelotas birth cohorts / Alicia MATIJASEVICH in Journal of Child Psychology and Psychiatry, 55-10 (October 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-10 (October 2014) . - p.1125-1134 Titre : Increase in child behavior problems among urban Brazilian 4-year olds: 1993 and 2004 Pelotas birth cohorts Type de document : texte imprimé Auteurs : Alicia MATIJASEVICH, Auteur ; Elizabeth MURRAY, Auteur ; Alan STEIN, Auteur ; Luciana ANSELMI, Auteur ; Ana Maria B.

VICTORA, Auteur Article en page(s) : p.1125-1134 Langues : Anglais (eng) Mots-clés : Mental health  behavior problems  child behavior check list  longitudinal studies Index. décimale : PER Périodiques Résumé : Background There are an increasing number of reports on time trends in child and adolescent psychological problems but none from low- and middle-income countries, and very few covering the preschool period. The aim was to investigate changes in preschool behavioral/emotional problems in two birth cohorts from a middle-income country born 11 years apart. Methods We analyzed data from the 1993 and 2004 Pelotas birth cohort studies from Brazil. A subsample of 4-year olds from the 1993 cohort (634) and all 4-year olds from the 2004 cohort (3750) were assessed for behavioral/emotional problems through maternal report using the Child Behavior Checklist (CBCL). Response rates in these two population-based cohorts were above 90%. Results We found a significant increase in CBCL total problems, internalizing and externalizing mean scores over the 11-year period. For 1993 and 2004 Pelotas cohorts, respectively, CBCL mean values (SE) total problems scores were 27.9 (0.8) and 34.7 (0.3); for internalizing scores, 5.7 (0.2) and 6.3 (0.1) and for externalizing scores, 12.4 (0.4) and 15.5 (0.1). After adjusting for confounding variables, the largest increase from 1993 to 2004 was identified in the aggressive behavior syndrome score (Cohen's d = .50), followed by the externalizing problem score (Cohen's d = .40) and CBCL total problem score (Cohen's d = .36), respectively. The rise in child psychological problems was more marked in children from families with fewer assets and with less educated mothers. Conclusions Our findings provide evidence for a substantial increase in preschool behavioral problems among children in Brazil over an 11-year period.

Sex differences in the association between foetal growth and child attention at age four: specific vulnerability of girls / Elizabeth MURRAY in Journal of Child Psychology and Psychiatry, 56-12 (December 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-12 (December 2015) . - p.1380-1388 Titre : Sex differences in the association between foetal growth and child attention at age four: specific vulnerability of girls Type de document : texte imprimé Auteurs : Elizabeth MURRAY, Auteur ; Alicia MATIJASEVICH, Auteur ; Iná S.

However, despite both foetal growth and child attention problems differing by sex, few studies have examined sex differences in this association. Furthermore, no studies have been conducted in low- and middle-income countries, where there are higher rates of perinatal problems. This study aimed to test for sex differences in the association between foetal growth indices and attention problems at age four, in a large, prospective birth cohort from a middle-income country. Methods A total of 3,749 neonates from the 2004 Pelotas birth cohort (Brazil) with foetal growth indices collected at birth [low birthweight (LBW), small-for-gestational age (SGA), head circumference (HC), head circumference-to-abdominal circumference ratio (HC/AC) and ponderal index (PI)], were assessed for attention problems using the Child Behaviour Checklist at age four. Ordinal logistic regression with successive adjustment for maternal, demographic, gestational, perinatal and child nutrition/mother–child morbidity, was conducted separately for girls and boys. Results In girls, attention difficulties were associated with being born SGA (OR = 1.40, CI = 1.08–1.82, p = .012), with a small HC (OR = 1.52, CI = 1.11–2.08, p = .009), or with a low PI (OR = 1.29, CI = 1.08–1.54, p = .005). There were no associations identified between attention difficulties and any foetal growth indices in boys. Conclusions Our results show that girls with impaired foetal growth may be particularly at risk of attention difficulties in childhood. This is consistent with emerging research that female foetuses may be more vulnerable to certain suboptimal intrauterine environments, inducing epigenetic changes that lead to disturbed growth and long-term developmental impairment.
