Psoriasis and mental health in adolescents: A cross-sectional study within the Danish National Birth Cohort.

Background: Psoriasis is a chronic skin disease associated with lower quality of life and higher risk of anxiety and depression in adults. We investigate whether adolescents with psoriasis also experience poorer mental health than their peers.

Methods: In this cross-sectional study, we included questionnaire data on psoriasis and mental health from the 18-year follow-up of the Danish National Birth Cohort.

Gestational age and trajectories of body mass index and height from birth through adolescence in the Danish National Birth Cohort.

Preterm birth is associated with smaller body dimensions at birth. The impact on body size in later life, measured by body mass index (BMI) and height, remains unclear. A prospective register-based cohort study with 62,625 singletons from the Danish National Birth Cohort born 1996-2003 for whom information on gestational age (GA) at birth, length or weight at birth, and at least two growth measurements scheduled at the ages of 5 and 12 months, and 7, 11 and 18 years were available.

Gestational age at birth and body size from infancy through adolescence: An individual participant data meta-analysis on 253,810 singletons in 16 birth cohort studies.

Background: Preterm birth is the leading cause of perinatal morbidity and mortality and is associated with adverse developmental and long-term health outcomes, including several cardiometabolic risk factors and outcomes. However, evidence about the association of preterm birth with later body size derives mainly from studies using birth weight as a proxy of prematurity rather than an actual length of gestation. We investigated the association of gestational age (GA) at birth with body size from infancy through adolescence.

Maternal stress during pregnancy and gestational duration: A cohort study from the Danish National Birth Cohort.

Background: Preterm birth is one of the most important contributors to neonatal mortality and morbidity. Experiencing stress during pregnancy may increase the risk of adverse birth outcomes, including preterm birth. This association has been observed in previous studies, but differences in measures used limit comparability.
