Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 49-9 (September 2008) . - p.967-976 Titre : Fetal origins of child non-right-handedness and mental health Type de document : Texte imprimé et/ou numérique Auteurs : Alina RODRIGUEZ, Auteur ; Ulla WALDENSTROM, Auteur Année de publication : 2008 Article en page(s) : p.967-976 Langues : Anglais (eng) Mots-clés : ADHD atypical-laterality child-mental-health handedness language-difficulties prenatal Index. décimale : PER Périodiques Résumé : Background: Environmental risk during fetal development for non-right-handedness, an index of brain asymmetry, and its relevance for child mental health is not fully understood. Methods: A Swedish population-based prospective pregnancy–offspring cohort was followed-up when children were five years old (N = 1714). Prenatal environmental risk exposures were the number of ultrasound examinations and maternal distress during pregnancy. Child mental health, including symptoms of attention deficit hyperactivity disorder (ADHD), language difficulties, and care-seeking for child behavior problems, was assessed via maternal and/or kindergarten teacher's ratings. Results: Prenatal exposure to maternal depressive symptoms and critical life events were associated with increased risk of child non-right-handedness and mixed handedness, after adjustment for parity, maternal age, birth outcomes, infant sex, and parental handedness. No association was found between handedness and number of ultrasound examinations. Non-right and mixed-handedness, rather than left-handedness, were associated with increased risk of language difficulties and particularly with ADHD symptoms, after adjustment for current parental ADHD symptoms, current maternal depressive symptoms, birth outcomes, smoking during pregnancy, depressive symptoms and critical life events. Problems were significant enough to prompt mothers to seek care for children's behavioral problems, and parents were more likely to have received advice from the children's kindergarten teachers to seek care. Conclusions: This study suggests that mixed-handedness, i.e., reflecting atypical brain laterality, can be a marker of both severity of prenatal exposure to maternal distress and of increased risk of ADHD symptoms in childhood. Our results support the idea that the fetal environment plays a role in subsequent child mental health.

Maternal pre-pregnancy obesity and risk for inattention and negative emotionality in children / Alina RODRIGUEZ in Journal of Child Psychology and Psychiatry, 51-2 (February 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-2 (February 2010) . - p.134-143 Titre : Maternal pre-pregnancy obesity and risk for inattention and negative emotionality in children Type de document : Texte imprimé et/ou numérique Auteurs : Alina RODRIGUEZ, Auteur Année de publication : 2010 Article en page(s) : p.134-143 Langues : Anglais (eng) Mots-clés : ADHD emotion-regulation prenatal overweight/obesity longitudinal-studies Index. décimale : PER Périodiques Résumé : Objective: This study aimed to replicate and extend previous work showing an association between maternal pre-pregnancy adiposity and risk for attention deficit hyperactivity disorder (ADHD) symptoms in children. Methods: A Swedish population-based prospective pregnancy–offspring cohort was followed up when children were 5 years old (N = 1,714). Mothers and kindergarten teachers rated children's ADHD symptoms, presence and duration of problems, and emotionality. Dichotomized outcomes examined difficulties of clinical relevance (top 15% of the distribution). Analyses adjusted for pregnancy (maternal smoking, depressive symptoms, life events, education, age, family structure), birth outcomes (birth weight, gestational age, infant sex) and concurrent variables (family structure, maternal depressive symptoms, parental ADHD symptoms, and child overweight) in an attempt to rule out confounding. Results: Maternal pre-pregnancy overweight and obesity predicted high inattention symptom scores and obesity was associated with a two-fold increase in risk of difficulties with emotion intensity and emotion regulation according to teacher reports. Means of maternal ratings were unrelated to pre-pregnancy body mass index (BMI). Presence and duration of problems were associated with both maternal over and underweight according to teachers. Conclusions: Despite discrepancies between maternal and teacher reports, these results provide further evidence that maternal pre-pregnancy overweight and obesity are associated with child inattention symptoms and extend previous work by establishing a link between obesity and emotional difficulties. Maternal adiposity at the time of conception may be instrumental in programming child mental health, as prenatal brain development depends on maternal energy supply. Possible mechanisms include disturbed maternal metabolic function. If maternal pre-pregnancy obesity is a causal risk factor, the potential for prevention is great.

Prevalence of purging at age 16 and associations with negative outcomes among girls in three community-based cohorts / Francesca SOLMI in Journal of Child Psychology and Psychiatry, 56-1 (January 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-1 (January 2015) . - p.87-96 Titre : Prevalence of purging at age 16 and associations with negative outcomes among girls in three community-based cohorts Type de document : Texte imprimé et/ou numérique Auteurs : Francesca SOLMI, Auteur ; Kendrin R.

FIELD, Auteur ; Nadia MICALI, Auteur Article en page(s) : p.87-96 Langues : Anglais (eng) Mots-clés : Adolescence  epidemiology  prevalence  eating behaviour  eating disorder Index. décimale : PER Périodiques Résumé : Background The comorbidity of purging behaviours, such as vomiting, inappropriate use of laxatives, diuretics or slimming medications, has been examined in literature. However, most studies do not include adolescents, individuals who purge in the absence of binge eating, or those purging at subclinical frequency. This study examines the prevalence of purging among 16-year-old girls across three countries and their association with substance use and psychological comorbidity. Methods Data were obtained by questionnaire in 3 population-based cohorts (Avon Longitudinal Study of Parents and Children (ALSPAC), United Kingdom, n = 1,608; Growing Up Today Study (GUTS), USA, n = 3,504; North Finland Birth Cohort (NFBC85/86), Finland, n = 2,306). Multivariate logistic regressions were employed to estimate associations between purging and outcomes. Four models were fit adjusting for binge eating and potential confounders of these associations. Results In ALSPAC, 9.7% of girls reported purging in the 12-months prior to assessment, 7.3% in GUTS, and 3.5% in NFBC. In all 3 cohorts, purging was associated with adverse outcomes such as binge drinking (ALSPAC: odds ratio (OR) = 2.0, 95% confidence interval (CI) = 1.4–2.9; GUTS: OR = 2.5, 95% CI = 1.5–4.0; NFBC: OR = 1.7, 95% CI = 1.0–2.8), drug use (ALSPAC: OR = 2.9, 95% CI = 1.8–4.7; GUTS: OR = 4.5, 95% CI = 2.8–7.3; NFBC: OR = 4.1, 95% CI = 2.6–6.6), depressive symptoms in ALSPAC (OR = 2.2, 95% CI = 1.5–3.1) and GUTS(OR = 3.7, 95% CI = 2.2–6.3), and several psychopathology measures including clinical anxiety/depression in NFBC (OR = 11.2, 95% CI = 3.9, 31.7). Conclusions Results show a higher prevalence of purging behaviours among girls in the United Kingdom compared to those in the United States and Finland. Our findings support evidence highlighting that purging in adolescence is associated with negative outcomes, independent of its frequency and binge eating.
