RESUMO
BACKGROUND: B12 vitamin is essential for the functioning of the nervous system and the production of mood-related neurotransmitters. However, information on its association with postpartum depression (PPD) is limited. OBJECTIVE: To examine the effect of serum vitamin B12 levels during pregnancy on PPD, in healthy pregnant women from the Mediterranean region of Catalonia, Spain. METHOD: This longitudinal study included a subsample of women at 54 days (7.7 weeks) postpartum (n = 336), who participated in the ECLIPSES Study conducted out in Tarragona, Spain. Maternal concentrations of vitamin B12 were determined in the first and third trimester of pregnancy and sociodemographic, nutritional, and psychological data were collected. PPD was assessed using the Edinburgh Postnatal Depression Scale (EPDS). RESULTS: The prevalence of probable PPD was 21%. After adjusting for sociodemographic, lifestyle, biochemical parameters, and postpartum characteristics the regression model showed a negative association between EPDS scores and the highest quartile of serum vitamin B12 (first quartile (reference) vs. fourth quartile), (ß = -1.267, 95% CI = -2.461, -0.073, p = 0.038). CONCLUSION: Maintaining a normal-high level of vitamin B12 during early pregnancy can contributes to preventing PPD.
RESUMO
Maternal vitamin B12 deficiency has been associated with disturbed cognitive functioning in offspring at different ages during childhood. However, this association has not been explored in pre-school-age children. The objective of this study was to examine the association between maternal vitamin B12 levels at the beginning and end of pregnancy and cognitive functioning in their children at 4 years of age. This longitudinal prospective study included a subsample of pregnant women and their children aged 4 years (n = 249) who participated in the ECLIPSES Study conducted in the province of Tarragona, Spain, from 2013 to 2017. Maternal vitamin B12 concentrations were determined in the first and third trimesters, and sociodemographic, nutritional and psychological data were collected. The children's cognitive functioning was assessed using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV) and subtests of the Neuropsychological Assessment of Development (NEPSY-II). The multivariable models showed a significant relationship between vitamin B12 and the working memory index in the first trimester of the pregnancy but not in the third trimester. Children of mothers in the second vitamin B12 level tertile (314-413 pg/mL) (ß = 6.468, 95% confidence interval [CI]: = 2.054, 10.882, p = 0.004) and third vitamin B12 level tertile (≥414 pg/mL) (ß = 4.703, 95% CI: = 0.292, 9.114, p = 0.037) scored higher in the working memory index of the WPPSI-IV than the children of mothers with vitamin B12 levels in the first tertile (<314 pg/mL). Maintaining an adequate level of maternal vitamin B12 during early pregnancy contributes to improved performance in childhood working memory at 4 years of age.

Prenatal iron supplementation improves children's health and cognitive performance, but few studies explore behavioural development. This study assessed the effects of adjusting prenatal iron supplementation to maternal iron stores during early pregnancy on children's behavioural problems. Randomized controlled trial conducted in Tarragona (Spain) involving 230 nonanaemic pregnant women and their children after a 4-year follow-up. Based on haemoglobin (Hb) levels before gestational week (GW) 12, women receive different iron doses: those with Hb = 110-130 g/L were randomized to receive 80 or 40 mg/day and those with Hb > 130 g/L were randomized to receive 20 or 40 mg/day. Maternal iron stores at GW12 were classified using serum ferritin (SF) as low (SF < 15 µg/L), normal (SF = 15-65 µg/L), and normal-high (SF > 65 µg/L). Children's behaviour was assessed by parents using the Child Behaviour Checklist for ages 1.5-5 years and the Behaviour Rating Inventory of Executive Function-Preschool Version, and by teachers using the Teacher's Report Form for ages 1.5-5 years. Multivariable regression models were performed. Taking 80 mg/day of iron improved child behaviour when women had low iron stores but worsened it when mothers had normal-high iron stores, except for depressive and attention/hyperactivity problems. Taking 20 mg/day of iron improved behaviour only in those children whose mothers had SF > 65 µg/L in early pregnancy. Additionally, executive functioning improved at high doses of prenatal iron when maternal baseline SF < 15 µg/L. Adjusting prenatal iron supplementation to both maternal baseline Hb levels and iron stores reduces behavioural problems in 4-year-old children.

Prenatal exposure to air pollution, even at low levels, has been associated with negative effects on a child's neuropsychological functioning. The present work aimed to investigate the associations between prenatal exposure to air pollution on a child's cognitive, language, and motor function at 40 days of age in a highly exposed area of Spain. From the ECLIPSES study population, the present work counted 473 mother-child pairs. Traffic-related air pollution levels at home addresses during the whole pregnancy were estimated including particulate matter (PM) with an aerodynamic diameter <2.5 µm (PM2.5), <10 µm (PM10) and 2.5-10 µm (PMcoarse), PM2.5absorbance, nitrogen dioxide (NO2), other nitrogen oxides (NOx), and ozone (O3) using land-use regression models developed within ESCAPE and ELAPSE projects. Children's cognitive, language, and motor functions were assessed using the Bayley Scales of Infant Development 3rd edition (BSID-III) at around 40 days of age. Linear regression models were adjusted for maternal biological, sociodemographic and lifestyle characteristics, area deprivation index, and amount of greenness around the home's address. All air pollutants assessed, except PM2.5 absorbance, were associated with lower motor function in children, while no association was observed between prenatal exposure to air pollution and cognitive and language functions. This finding highlights the need to continue raising awareness of the population-level impact that maternal exposure to air pollution even at low levels can have on the neuropsychological functions of children.

BACKGROUND: Prenatal prescription of standard iron supplements to prevent iron deficiency appears not to be appropriate for all women and their children, as some women may be at risk of iron deficiency and others at risk of iron excess early in pregnancy. The present study aimed to assess whether prenatal iron supplementation adapted to the needs of each pregnant woman affects their child's neurodevelopment. METHODS: Follow-up of a community-based RCT involving 503 mother-child pairs. Non-anaemic pregnant women recruited in Tarragona (Spain) early in pregnancy were prescribed a daily iron dose based on their initial haemoglobin levels: Stratum 1 (Hb = 110-130 g/L, 80 or 40 mg/d of iron) and Stratum 2 (Hb > 130 g/L, 40 or 20 mg/d of iron). Women receiving 40 mg/d were considered the control group in each Strata. The child's neurodevelopment was assessed at 40 days of age using the Bayley Scales of Infant Development-III (BSID-III). Adjusted multiple regression models were used. RESULTS: Multiple regression analyses showed no association between the intervention and control group within each Strata on the BSID-III scores on any of the developmental scales in children, including cognitive, language, and motor development: Stratum 1 (ß 1.46, 95%CI -2.15, 5.07; ß 1.30, 95%CI -1.99, 4.59; and ß 2.04, 95%CI -3.88, 7.96, respectively) and Stratum 2 (ß -4.04, 95%CI -7.27, 0.80; ß -0.36, 95%CI -3.47, 2.75; and ß -3.76, 95%CI -9.30, 1.78, respectively). CONCLUSIONS: In non-anaemic women in early pregnancy, no differences were found in the cognitive, language and motor development of children at 40 days of age between the dose of iron tested in each case -adjusted to initial Hb levels- compared to the dose of the control group. Further studies are guaranteed to confirm our findings. TRIAL REGISTRATION: The ECLIPSES study was registered at www.clinicaltrialsregister.eu as EudraCT number 2012-005,480-28.

BACKGROUND: During pregnancy a high amount of fatty acids (FA) is necessary to meet foetus demands, which vary during gestation. The present study describes the changes in maternal fatty acid concentrations during pregnancy in a sample of pregnant women. METHODS: This is a longitudinal study of 479 pregnant women who were monitored from the first trimester to third trimester of pregnancy. Data on maternal characteristics were recorded and a serum sample was collected in each trimester. The fatty acid profile (saturated (SFA: total, lauric acid, myristic acid, palmitic acid, stearic acid), monounsaturated (MUFA: total, palmitoleic acid, oleic acid) and polyunsaturated fatty acids (PUFA: total omega-6 (n-6), linoleic acid, dihomo-γ-linolenic acid, arachidonic acid (AA), total omega-3 (n-3), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA)) was analysed with a gas chromatography-mass spectrometry combination. RESULTS: From the first trimester to third trimester of pregnancy, a significant increase in total SFA, total MUFA and total n-6 PUFA was found. (p < 0.001). Nevertheless, the serum concentration of arachidonic acid (AA), eicosapentaenoic acid (EPA) and total n-3 PUFA decreased during gestation (p < 0.001). A statistically non-significant result was observed for the docosahexaenoic acid (DHA) serum concentration between the first and third trimesters of pregnancy. Significant correlations were observed between each total fatty acid concentrations of the first and third trimesters. CONCLUSION: The circulating serum concentration of SFA, MUFA and n-6 PUFA increases during pregnancy, whereas essential fatty acids such as AA and EPA decrease, and DHA remains unchanged. Further research is necessary to understand the role played by FA throughout gestation.

The aim of this study is to assess the relationship between pre- and perinatal factors and ADHD in a sample of scholars exploring differences between ADHD presentations and spectrum of severity. A total of 6720 scholars (aged 3-4 and 10-11) participated in a double-phase epidemiologic cross-sectional study (Epidemiological Study of Neurodevelopmental Disorders, EPINED), and a sample of 646 scholars (ADHD risk, ASD risk and controls without risk) were individually assessed in the second phase of the study. The ADHD diagnosis, based on DSM-5 criteria, was performed with the Kiddie-Schedule for Affective Disorders & Schizophrenia, Present & Lifetime Version. Associations for the different ADHD presentations between prenatal, perinatal and postnatal factors and ADHD (n = 168), subclinical ADHD (n = 88) and non-ADHD (n = 310) were analysed. Logistic regression models showed that gestational diabetes (p = 0.012), instrumental delivery (p = 0.011), family history of psychopathology (p = 0.033) and maternal ADHD phenotype (p = 0.023) were associated with ADHD. These factors were related to the hyperactive-impulsive and combined presentations, but they were not related to the inattentive presentation. Maternal weight gain was associated with subclinical ADHD. In conclusion, metabolic disorder in the pregnancy, difficulties in childbirth and specific family phenotype were related to ADHD, specifically with hyperactive-impulsive presentation, but not in subclinical ADHD.

Experiencing negative emotional states during pregnancy has been linked to adverse outcomes for mother and offspring. Our study aims were to compare the perinatal emotional states and obstetrical variables between pregnant women recruited in Spain (n = 202) and Italy (n = 103), and to investigate prenatal anxiety related factors. The study had two phases. In the 1st phase (3rd trimester of pregnancy), prenatal anxiety was assessed using the State-Trait Anxiety Inventory (STAI); other prenatal and sociodemographic variables were also collected. In the 2nd phase (40 days postpartum), the STAI and the Edinburgh Postnatal Depression Scale were administered. Compared to the Spanish sample, the Italian sample presented higher STAI state and STAI factor 1 mean scores (22.5 vs. 18.6 and 10.0 vs. 7.2), shorter gestations (mean gestation weeks: 39.1 vs. 39.8), more unplanned pregnancies (31.1% vs. 16.4%), and more cesareans deliveries (42.5% vs. 16.0%). Low socioeconomic levels, younger ages, previous miscarriages and unplanned pregnancies were related to prenatal anxiety. Postpartum depression rates was 31.3% and there were no differences between countries. Our results suggested that it may be interesting in both countries to create a prenatal monitoring protocol that attaches more importance to emotional wellbeing both during pregnancy and in the long term.

Objective: To study prospectively the effect of prenatal smoke exposure (PSE) on child neuropsychological function and intelligence quotient (IQ).Background: PSE has been associated with adverse effects on child neurodevelopment. However, some studies reported that these associations disappear after adjustment for potential confounders.Methods: A cohortof 248 mothers-child dyad was followed from the first trimester of pregnancy until children were 7.5 years old. PSE was recorded during pregnancy by questionnaire and plasma cotinine. The Wechsler Intelligence Scale for Children, the Neuropsychological Assessment of Executive Functions for Children (ENFEN) and the School Neuropsychological Maturity Questionnaire were administered at 7.5 years of age. The effect of PSE on child IQ and neuropsychological function was assessed with ANCOVA, adjusting for obstetric, neonatal and sociodemographic factors.Results: Children whose mothers smoked throughout pregnancy scored lower in interference (ENFEN) compared to unexposed children (F = 4.1; p = .008). The results showed no differences in other executive functions, verbal and visual memory and IQ between the PSE groups.Conclusion: PSE had little effect on child neuropsychological outcome and was limited to mental flexibility. Nevertheless, these findings support further efforts aimed at encouraging mothers to quit smoking in pregnancy.

Anxiety Disorders (AD) are the most prevalent mental disorders in children and adolescents and a relevant public health problem. The study aimed to determine the prevalence of ADs, the comorbidity, the sociodemographic correlates, and the functional impairment in Spanish school children. The initial sample included 1514 subjects (720 boys; mean age = 10.2), who filled out the Screen for Children's Anxiety-Related Emotional Disorders (SCARED). In a second phase, 562 subjects at risk and not-at-risk of anxiety were assessed with the Mini-International Neuropsychiatric Interview for Children and Adolescents to obtain DSM-5 diagnoses. Two years later (third phase; mean age 13.5), the SCARED was re-administered. The weighted prevalence of any AD was 11.8%. The most prevalent subtypes were specific phobia (16.2%) and generalized anxiety disorder (GAD) (6.9%). Girls showed higher rates of social anxiety (5.5%) than boys. Apart from being female, low socioeconomic status was also a risk factor for AD. The heterotypic comorbidity of any AD was 40.7%, and the homotypic comorbidity was 35.6%. After controlling for age and other ADs, we found that subjects with GAD had the highest risk of having other depressive disorders and ADs. Only 33.3% of the subjects with any AD had sought professional help. 52.9% of the subjects diagnosed with any of the ADs still had anxiety symptoms after a 2-year follow-up. These findings highlight that in Spain, ADs in early adolescence are an important public health problem and that detection and access to treatment need to be improved.

OBJECTIVE: To determine the associations between haemoconcentration at the end of pregnancy (third trimester and delivery) and neonatal behaviour in healthy pregnant women supplemented with moderate doses of Fe. DESIGN: A prospective longitudinal study in which obstetric and clinical history, maternal toxic habits, maternal anxiety and Hb levels were recorded at the third trimester and delivery. Neonatal behaviour was assessed at 48-72 h of age using the Neonatal Behavioral Assessment Scale. SETTING: Unit of Obstetrics and Gynaecology of the Sant Joan University Hospital in Reus, Tarragona (Spain). SUBJECTS: A total of 210 healthy and well-nourished pregnant women and their full-term, normal-weight newborns. RESULTS: The results showed that, after adjusting for confounders, in the third trimester the risk of haemoconcentration (6·2 % of pregnant women) was related to decreased neonatal state regulation (B=-1·273, P=0·006) and alertness (B=-1·848, P=0·006) scores. In addition, the risk of haemoconcentration at delivery (12·0 % of pregnant women) was also related to decreased neonatal state regulation (B=-0·796, P=0·021) and poor robustness and endurance (B=-0·921, P=0·005) scores. CONCLUSIONS: Our results show that the risk of haemoconcentration at the end of pregnancy is related to the neonate's neurodevelopment (and self-regulation capabilities), suggesting that Fe supplementation patterns and maternal Fe status during pregnancy are important factors for neurodevelopment which may be carefully controlled.

Objectives To study the longitudinal effects of prenatal nicotine exposure on cognitive development, taking into consideration prenatal and postnatal second-hand smoke exposure. Methods A cohort follow up study was carried out. One hundred and fifty-eight pregnant women and their infants were followed during pregnancy and infant development (at 6, 12, 30 months). In each trimester of pregnancy and during postnatal follow-up, a survey was administered to obtain sociodemographic data and the details of maternal and close familial toxic habits. Obstetric and neonatal data were obtained from hospital medical records. To assess cognitive development, the Bayley Scales of Infant Development were applied at 6, 12 and 30 months; to assess language development, the MacArthur-Bates Communicative Development Inventories were applied at 12 months and the Peabody Picture Vocabulary Test at 30 months. Results After adjustment for confounding variables, the results showed that infants prenatally exposed to cigarette smoke recorded poor cognitive development scores. Language development was most consistently affected, specifically those aspects related to auditory function (vocalizations, sound discrimination, word imitation, prelinguistic vocalizations, and word and sentence comprehension). Conclusions for Practice Irrespective of prenatal, perinatal and sociodemographic data (including infant postnatal nicotine exposure), prenatal exposure to cigarette smoke and second-hand smoke affect infant cognitive development, especially language abilities.

BACKGROUND: Currently, there is no consensus regarding iron supplementation dose that is most beneficial for maternal and offspring health during gestation. Recommended iron supplementation dose does not preempt anemia in around 20% of the pregnancies, nor the risk of hemoconcentration in 15%. This deficit, or excess, of iron prejudices the mother-child wellbeing. Therefore the aims of the study are to determine the highest level of effectiveness of iron supplementation adapted to hemoglobin (Hb) levels in early pregnancy, which would be optimum for mother-child health. DESIGN: Randomized Clinical Trial (RCT) triple-blindedSetting: 10 Primary Care Centers from Catalunya (Spain)Study subjects: 878 non-anemic pregnant women at early gestation stage, and their subsequent newborns METHODS: The study is structured as a RCT with 2 strata, depending on the Hb levels before week 12 of gestation. Stratum #1: If Hb from 110 to 130 g/L, randomly assigned at week 12 to receive iron supplement of 40 or 80 mg/d. Stratum #2: If Hb >130 g/L, randomly assigned at week 12 to receive iron supplement of 40 or 20 mg/d. MEASUREMENTS: In the mother: socio-economic data, clinical history, food item frequency, lifestyle and emotional state, and adherence to iron supplement prescription. Biochemical measurements include: Hb, serum ferritin, C reactive protein, cortisol, and alterations in the HFE gene (C282Y, H63D). In children: ultrasound fetal biometry, anthropometric measurements, and temperament development.Statistical analyses, using the SPSS program for Windows, will include bivariate and multivariate analyses adjusted for variables associated with the relationship under study. DISCUSSION: Should conclusive outcomes be reached, the study would indicate the optimal iron supplementation dose required to promote maternal and infant health. These results would contribute towards developing guidelines for good clinical practice.

The obsessive-compulsive manifestations course was assessed with the Leyton obsessional inventory-child version survey (LOI-CV) in a 3-year prospective study, using a non-clinical sample. From an initial sample of 1,514 school-age children who underwent symptoms screening for obsessive-compulsive, anxiety and depression, 562 subjects (risk group/without risk group) were re-assessed in the 2nd phase and 242 subjects were monitored after 3 years. LOI-CV scores significantly decreased over time independently of age and gender. The prevalence, persistence and incidence for two levels of severity of obsessivecompulsive manifestations ranged between 4.8-30.4%, 9.3-28.4% and 1.1-14.4%, respectively. 34.6-64.5% of obsessive-compulsive symptomatology was predicted by anxiety, depressive and obsessive-compulsive symptoms. For the obsessiveness (less severe form of obsessive-compulsive manifestations), the depressive symptoms were not predictors. Gender and socioeconomic status were not related with obsessive-compulsive manifestations. These data support a substantial continuity of the obsessive-compulsive manifestations and the existence of different levels of severity within the obsessive-compulsive spectrum.

Omega-3 Long-Chain Polyunsaturated Fatty Acids (n-3 LCPUFAs) play a key role in early neurodevelopment, but evidence from observational and clinical studies remains inconsistent. This study investigates the association between maternal n-3 LCPUFA, Docosahexaenoic Acid (DHA), and eicosapentaenoic acid (EPA) concentrations during pregnancy and infant development functioning at 40 days. This study includes 348 mother-infant pairs. Maternal serum concentrations were assessed in the first and third trimesters alongside sociodemographic, clinical, nutritional, psychological, and obstetrical data. At 40 days, the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) was administered. An adjusted analysis revealed that lower first-trimester n-3 LCPUFA and DHA concentrations are associated with better infant motor development. These results underscore the potential significance of the maternal n-3 LCPUFA status in early pregnancy for influencing fetal neurodevelopment. However, the complexity of these associations necessitates further investigation, emphasizing the urgent need for additional studies to comprehensively elucidate the nuanced interplay between the maternal n-3 LCPUFA status and infant neurodevelopment.

Autism and attention deficit hyperactivity disorder (ADHD) comorbidity in the school population have been understudied. This study estimates its prevalence considering both parents' and teachers' reports and clinical diagnosis. Sociodemographic, clinical, and cognitive data were compared by diagnostic groups: autism, ADHD, autism and ADHD, subthreshold autism spectrum disorder (ASD), subthreshold ADHD, and children without neurodevelopmental conditions. Following a two-phase design, 3727 parents and teachers (1802 preschoolers, 1925 school-age children) participated in the first phase. Subsequently, 781 participants underwent individual assessment for DSM-5 diagnoses. The estimated prevalence of the comorbid diagnosis was 0.51% (0.28%-0.74%), with significant sex differences (0.16% girls, 0.89% boys). The cooccurrence of symptoms of autism and ADHD reported by parents or teachers was 3.2% and 2.6%, respectively. ADHD comorbidity was observed in 32.8% of autistic children and 31.4% of those with subthreshold ASD. ASD comorbidity was observed in 9.8% of children with ADHD and 5.7% of those with subthreshold ADHD. Comorbidity was reported by at least one informant in 95% of children. Only 15.8% of children with autism and ADHD had been previously diagnosed with both conditions. Early detection and accurate comorbidity diagnosis are crucial to address the clinical and socio-educational needs of these children.

Based on data from a three-year longitudinal study, we assess the effect, according to gender, of emotional psychopathology in preadolescence on anthropometric and body composition parameters in adolescence (N = 229). Psychopathology was assessed using the Screen for Childhood Anxiety and Related Emotional Disorders, the Children's Depression Inventory and the MINI-International Neuropsychiatric Interview for Kids. Body fat percentage (%BF), waist circumference (WC) and body mass index (BMI) were also determined. Following analysis with adjusted multiple regression models, the results indicated that symptoms of depression and separation anxiety were significantly associated with increased WC and BMI in boys, and that somatic symptoms were associated with increased WC and %BF in girls. Diagnosis of social phobia, panic disorder or dysthymia led to significantly increased WC and/or BMI in boys and dysthymia increased WC in girls. These findings suggest that emotional psychopathology in preadolescence is associated with increased weight gain and abdominal fat in adolescence.

AIMS: This study provides information about the prevalence of somatic symptoms (Ss) in a population of Spanish children and adolescents and their distribution by age and gender. It also sheds light on which Ss are more associated with depression and anxiety and which are associated with more disability. METHOD: A sample of 2558 school children and adolescents aged 8-16 years old, 1297 girls, completed one questionnaire about Ss, and two about anxiety and depressive symptoms. RESULTS: About 37.6% reported at least one Ss, headache being the most prevalent. In terms of age distribution, 26.8% of children and 52.1% of adolescents reported Ss. Girls reported more Ss than did boys. These gender differences started at 13 years of age and decreased at 15. Headache, stomach-ache and muscle pain were the Ss that caused the most impairment. CONCLUSIONS: In general, both anxiety and depressive symptoms were related to all Ss, whereas anxiety symptoms were associated with fatigue and muscle pain [corrected].

BACKGROUND: Children with neurodevelopmental disorders (NDD) are often at risk of developing emotional problems. AIMS AND METHODS: The co-occurrence of anxiety and depression with ASD and/or ADHD was determined by exploring the association with children's clinical and neuropsychological functioning and their parent's mental health. To this end, we assessed 295 preschoolers (PRE; 4-5 years old) and 486 school-aged children (SCH; 10-11 years old) in Tarragona, Spain. NDD diagnoses were based on DSM-5. Emotional problems were assessed using Achenbach's scales. RESULTS: Emotional problems (PRE: 36%-78%; SCH: 32%-81%) were more common and more severe in participants with NDD than in controls and children in the ASD + ADHD school-aged group were the most affected. In ADHD, emotional problems were associated with more severe symptoms of attention deficit (PRE) and hyperactivity/impulsivity (SCH). In ASD + ADHD, emotional problems showed a trend of association with more severe ASD repetitive behaviours and impaired working memory, whereas in ASD were associated with greater overall ASD severity. CONCLUSIONS AND IMPLICATIONS: Children with NDD are vulnerable to emotional problems, which become more prevalent and interfering with age. Early detection and intervention aimed at tackling emotional problems can improve NDD prognosis.

BACKGROUND: Bullying is highly prevalent among children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD). This study investigates self-perceived bullying victimization and related sociodemographic, psychopathological, cognitive, and academic characteristics in pre-adolescents with ADHD compared to controls. METHOD: The participants were 424 pre-adolescents, 138 of whom had ADHD. Self-perceived bullying victimization was assessed with the Bullying and School Violence questionnaire. This study is part of a larger double-phase epidemiologic cross-sectional study. RESULTS: A total of 35% of the ADHD pre-adolescents self-reported bullying victimization. ADHD-combined presentation showed the highest prevalence of co-occurring self-perceived bullying victimization. After the effects of socioeconomic level, gender, place of birth, intelligence quotient and autism had been controlled, we observed that presenting ADHD increased the likelihood of self-perceived bullying victimization almost 3-fold. Having ADHD and self-perceived bullying victimization were significantly associated with higher rates of the co-occurrence of internalizing and externalizing psychological problems. Comorbidity with ASD was higher in ADHD + bullying cases. Pre-adolescents with ADHD had lower cognitive scores and worse academic outcomes regardless of whether they were being bullied or not. CONCLUSIONS: In bullying prevention and intervention, special attention should be paid to ADHD as a vulnerability factor for self-perceived victimization, with negative consequences for emotional well-being and behavior.
