Maternal Prepregnancy Obesity and Offspring Intelligence Quotient at 5 Years: A Multicohort Analysis.

Background: The relationship between maternal obesity and childhood cognitive development remains unclear. Prior studies did not adjust for important confounders, and preterm infants are a developmentally distinct group that remains scarcely examined.

Objectives: To determine whether maternal prepregnancy body mass index (BMI) is associated with offspring intelligence quotient (IQ) up to 5 years and whether this relationship varies with gestational age.

Future time perspectives and concerns among adolescents in 2022.

Future time perspectives (FTP) and future-related concerns in adolescence remain underexplored. We aimed to identify factors associated with limited FTP and describe future-related concerns. Data were drawn from a population-based sample of adolescents aged 14-17 participating in the SEROCoV-KIDS cohort study, in Geneva, Switzerland (October 2022).

Psychosocial factors mediate social inequalities in health-related quality of life among children and adolescents.

Background: The present analysis aimed to assess the mediating role of psychosocial and behavioural factors in socio-economic inequalities in health-related quality of life (HRQoL) among children and adolescents.

Methods: Cross-sectional data was drawn from the randomly selected SEROCoV-KIDS cohort study in Geneva, Switzerland. Associations of socio-economic conditions (parents' highest education, household financial situation) with HRQoL, psychosocial (parent-child relationship, school difficulties, friends, extracurricular activities) and behavioural factors (screen time, physical activity, green spaces time, sleep duration), along with associations of psychosocial and behavioural factors with HRQoL, were evaluated with generalized estimating equations.

Acne-Related Quality of Life and Mental Health Among Adolescents: A Cross-Sectional Analysis.

Backgrounds: Acne vulgaris is one of the most common skin conditions worldwide among adolescents. Beyond its physical manifestations, acne can leave invisible psychological scars.

Objectives: We aimed to examine the protective and risk factors of acne-related quality of life, and its association with mental health outcomes.

Maternal social deprivation and preterm birth: The PreCARE cohort study.

Background: Maternal exposure to unfavourable social conditions is associated with a higher rate of perinatal complications, such as placental vascular pathologies. A higher risk of preterm birth (PTB) has also been reported, and variations across studies and settings suggest that different patterns may be involved in this association.

Objective: To assess the association between maternal social deprivation and PTB (overall and by phenotype).
