Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 57-8 (August 2016) . - p.967-975 Titre : Association between immigrant background and ADHD: a nationwide population-based case–control study Type de document : texte imprimé Auteurs : Venla LEHTI, Auteur ; Roshan CHUDAL, Auteur ; Auli SUOMINEN, Auteur ; Mika GISSLER, Auteur ; Andre SOURANDER, Auteur Article en page(s) : p.967-975 Langues : Anglais (eng) Mots-clés : Attention-deficit hyperactivity disorder  epidemiology  immigration  parental  risk factor Index. décimale : PER Périodiques Résumé : Background Information about psychiatric disorders among those with immigrant parents is important for early detection and service development. The aim of this study is to examine the association between parental immigration and the diagnosis of attention-deficit hyperactivity disorder (ADHD) in offspring in Finland. Methods This matched case–control study was based on a national birth cohort. The sample included all singletons who were born in Finland in 1991–2005 and diagnosed with ADHD by the year 2011 (n = 10,409) and their matched controls (n = 39,124). Nationwide registers were used to identify participants and to gather information on the parents' country of birth and native language. Conditional logistic regression analyses were conducted using maternal and paternal migration status and region of birth as well as time since maternal migration as exposure factors. Results The likelihood of being diagnosed with ADHD was significantly increased among children of two immigrant parents [adjusted odds ratio (aOR) 4.7, 95% CI 3.4–6.6] and children of an immigrant father (aOR 1.9, 95% CI 1.6–2.2). The likelihood of receiving an ADHD diagnosis was equal among children whose mother was a recent immigrant when she gave birth and those whose mother had stayed in Finland at least for a year before birth. The association between parental migration and ADHD diagnosis was strongest among fathers born in sub-Saharan Africa or Latin America and among mothers born in sub-Saharan Africa or North Africa and Middle East. Children, whose parents were born in countries with low Human Development Index (HDI), were more often diagnosed with ADHD. Conclusions The increased likelihood of ADHD diagnosis among children of immigrants indicates increased exposure to environmental risk factors, differences in the use of health services, or challenges in diagnosing immigrants' children.

A biomarker-based study of prenatal smoking exposure and autism in a Finnish national birth cohort / Keely CHESLACK-POSTAVA in Autism Research, 14-11 (November 2021)  

Public ISBD [article]  inAutism Research > 14-11 (November 2021) . - p.2444-2453 Titre : A biomarker-based study of prenatal smoking exposure and autism in a Finnish national birth cohort Type de document : texte imprimé Auteurs : Keely CHESLACK-POSTAVA, Auteur ; Andre SOURANDER, Auteur ; Susanna HINKKA-YLI-SALOMAKI, Auteur ; Ian W. MCKEAGUE, Auteur ; Heljä-Marja SURCEL, Auteur ; Alan S. BROWN, Auteur Article en page(s) : p.2444-2453 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Autistic Disorder  Biomarkers  Case-Control Studies  Child  Female  Finland/epidemiology  Humans  Maternal Exposure  Pregnancy  Prenatal Exposure Delayed Effects/epidemiology  Smoking  autism  cotinine  prenatal exposure delayed effects  smoking Index. décimale : PER Périodiques Résumé : Maternal exposure to tobacco smoke during pregnancy is a common and persistent exposure linked to adverse neurodevelopmental outcomes in the offspring. However, previous studies provide mixed evidence regarding the relationship between prenatal smoking and offspring autism. This study used cotinine level, a biomarker for nicotine, to investigate the relationship between prenatal smoking and autism. The authors conducted a population-based case-control study nested in a national cohort of all births in Finland from 1987 to 2005. Cases diagnosed with childhood autism (ICD-10/9 code F84.0/299.0) through 2007 were identified using data from linked national registers. Each case was matched with a control on date of birth (±30 days), sex, and place of birth (N = 962 pairs). Maternal serum cotinine levels were prospectively measured in first- to early second-trimester serum samples archived in a national biobank using a quantitative immunoassay. Data were analyzed using conditional logistic regression. Prenatal maternal levels of serum cotinine were not associated with the odds of autism, whether cotinine was classified continuously, by deciles, or using previously defined categories corresponding to probable maternal smoking status. After adjusting for maternal age, paternal age, previous births, and any history of parental psychiatric disorder, the odds ratio for categorical high versus low cotinine, using a 3-level exposure variable, was 0.98 (95% CI = 0.76, 1.26; p = 0.88). In conclusion, this national birth cohort-based study does not provide evidence for an association between maternal cotinine, a biomarker of maternal smoking, and risk of autism. LAY SUMMARY: This study explored whether prenatal exposure to tobacco smoke in mothers is related to the diagnosis of autism in their children, by measuring the levels of cotinine, a biomarker for tobacco exposure, in stored serum samples drawn from mothers during pregnancy. The levels of cotinine in the mothers of children diagnosed with autism were similar to those in the mothers of control children of similar age and gender distribution.

Brief Report: Syndromes in Autistic Children in a Finnish Birth Cohort / Laura TIMONEN-SOIVIO in Journal of Autism and Developmental Disorders, 46-8 (August 2016)

Our data include all children diagnosed with ASD (n = 4441) according to Finnish Hospital Discharge Register in 1987–2000. Four controls per each case were matched to sex, birthplace, date of birth (±30 days) and residence in Finland (n = 17,695). The prevalence of specific congenital syndromes in the Finnish Register of Congenital Malformations was evaluated among the ASD group and the controls by sex. The results of this study suggest that there is an association between several etiologically different syndromes and ASD when compared to controls without ASD. Statistically significant associations were observed with 47,XYY, Sotos syndrome, neurofibromatosis I, and syndrome not otherwise specified. Syndromes were more common among males with ASD compared to controls. These results support the previous studies of etiological heterogeneity of ASD and have importance in clinical examination, management and rehabilitation.

Childhood antecedents of being a cigarette smoker in early adulthood. The Finnish 'From a Boy to a Man'Study / Solja NIEMELA in Journal of Child Psychology and Psychiatry, 50-3 (March 2009)

Methods: In 1989, a general population sample of 2946 8-year-old boys born in Finland in 1981 was assessed using the Rutter's parent and teacher questionnaires, and the Child Depression Inventory. This birth cohort was followed up in 1999, when the subjects reported for their obligatory military service at age 18. Information about cigarette smoking frequency was obtained from 78% (n = 2307) of the boys attending the study in 1989. Results: Childhood hyperactivity and self-reported depressive symptoms correlated with moderate daily (1–10 cigarettes), and heavy daily (>10 cigarettes) smoking at age 18. Conduct problems correlated with heavy daily smoking. A high level of childhood depressive symptoms, particularly in conjunction with a low educational level of the father, increased the risk of daily smoking. Emotional problems decreased the risk of smoking at age 18. In general, teacher reports had a better predictive power than parent reports for subsequent smoking. Conclusion: Future developmental studies with special focus on interaction between individual and environmental factors are warranted to reveal the mechanisms underlying the association between childhood psychopathology and adult smoking. In particular, the associations between childhood depression and future smoking need more clarification.

The cohort includes register data of 4,705 children born between 1987 and 2005 and diagnosed as cases of childhood autism, Asperger’s syndrome or pervasive developmental disorders—not otherwise specified. Each case was matched to four controls by gender, date of birth, place of birth, and residence in Finland. Epilepsy was associated with ASD regardless of the subgroup after adjusting for covariates. The associations were stronger among cases with intellectual disability, especially among females. Epilepsy’s age at onset was similar between the cases and controls regardless of the ASD subgroup. These findings emphasize the importance to examine the neurodevelopmental pathways in ASD, epilepsy and intellectual disability.
