We aimed to assess the associations between screen use and cognitive development in the French nationwide birth cohort. Methods Time and context of screen use were reported by parents at ages 2, 3.5 and 5.5. Vocabulary, non-verbal reasoning and general cognitive development were assessed with the MacArthur-Bates Communicative Development Inventory (MB) at age 2, the Picture Similarities subtest from the British Ability Scales (PS) at age 3.5 and the Child Development Inventory (CDI) at ages 3.5 and 5.5. Outcome variables were age-adjusted and standardized (mean = 100, SD = 15). Multiple imputations were performed among children (N = 13,763) with 1 screen use information and 1 cognitive measures. Cross-sectional and longitudinal associations between screen use and cognitive development were assessed by linear regression models adjusted for sociodemographic and birth factors related to the family and children, and children's lifestyle factors competing with screen use. Baseline cognitive scores were further considered in longitudinal analysis. Results TV-on during family meals at age 2, not screen time, was associated with lower MB scores at age 2 (? [95% CI] = 1.67 [ 2.21, 1.13]) and CDI scores at age 3.5 ( 0.82 [ 1.31, 0.33]). In cross-sectional analysis, screen time was negatively associated with CDI scores at ages 3.5 ( 0.67 [ 0.94, 0.40]) and 5.5 ( 0.47 [ 0.77, 0.16]), and, in contrast, was positively associated with PS scores (0.39 [0.07, 0.71]) at age 3.5. Screen time at age 3.5 years was not associated with CDI scores at age 5.5 years. Conclusions Our study found weak associations of screen use with cognition after controlling for sociodemographic and children's birth factors and lifestyle confounders, and suggests that the context of screen use matters, not solely screen time, in children's cognitive development.

Prenatal Exposure to Ambient Particulate Matter and Autism Spectrum Disorder in Children, a Case Control Study in France / Marion MORTAMAIS in Journal of Autism and Developmental Disorders, 56-9 (September 2026)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 56-9 (September 2026) . - p.3713-3725 Titre : Prenatal Exposure to Ambient Particulate Matter and Autism Spectrum Disorder in Children, a Case Control Study in France Type de document : texte imprimé Auteurs : Marion MORTAMAIS, Auteur ; Jeanne Sandrine ONGONO, Auteur ; Cécile MICHELON, Auteur ; Ian HOUGH, Auteur ; Emie SEYVE, Auteur ; Itai KLOOG, Auteur ; Cécile ZAROS, Auteur ; Marie-Aline CHARLES, Auteur ; Johanna LEPEULE, Auteur ; Amaria BAGHDADLI, Auteur Article en page(s) : p.3713-3725 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : A series of epidemiological studies conducted in the United States have consistently shown an increased risk of autism spectrum disorder (ASD) in children associated with pre- and postnatal exposure to ambient particulate matter (PM). In Europe, studies are scarce and results are inconsistent. We aimed to investigate the association between prenatal exposure to PM and the risk of ASD in France. ASD cases were participants from the ELENA cohort. Controls children from the ELFE cohort were matched by sex, year (± 2) and region of birth. Prenatal exposures to PM10 and to PM2.5 were estimated between 2008 and 2013 using innovative hybrid spatio-temporal models developed for France. Conditional logistic regression models adjusted for birth season, parent’s age at the child birth and parental education level were run. We included 125 ASD cases and 500 controls. Prenatal PM2.5 and PM10 median (IQR) concentration estimates were respectively 16.3 (3.9) µg/m3 and 22.9 (6.6) µg/m3 in the whole sample. The conditional logistic regression models showed Odds Ratios (ORs) (Confidence Interval 95%) for ASD risk of 0.72 (0.52–1.01) and 0.84 (0.58–1.22) for an IQR increase in PM2.5 and PM10 prenatal levels, respectively. When restricting population of ASD cases to children born the same year of controls, ORs were 1.79 (0.80–4.01) and 2.23 (0.71–9.04), respectively. Our results did not show that prenatal exposures to PM2.5 and PM10 were associated with the risk of ASD in children in France.
