[Influence of preconception period and pregnancy on birth outcomes and health of the child].

According to the Developmental Origins of Health and Disease hypothesis, the environment in which a fetus develops before birth has a profound impact on a child s long-term health. An adverse environment in the womb can lead to permanent changes in the structure and function of various organ systems, with possible negative long-term health consequences. In the Generation R Study, a longitudinal, observational cohort study in Rotterdam, these long-term effects of prenatal exposure are investigated.

Associations of fetal and infant growth with pubertal timing.

Objective: Impaired fetal and infant growth may cause alterations in developmental programming of the hypothalamic-pituitary-gonadal axis and subsequently pubertal development. We aimed to assess associations between fetal and infant growth and pubertal development.

Design: Population-based prospective birth cohort.

cord blood metabolite profiles and childhood cardio-metabolic outcomes in a population-based cohort.

Introduction: Adverse exposures in utero might cause adaptations of cardiovascular and metabolic organ development, predisposing individuals to an adverse cardio-metabolic risk profile from childhood onwards. We hypothesized that adaptations in metabolic pathways underlie these associations and examined associations of metabolite profiles at birth with childhood cardio-metabolic risk factors.

Methods: The study included 763 mother-child pairs participating in an ongoing population-based prospective cohort study with an overall low disease risk.

Prenatal polycyclic aromatic hydrocarbons exposure and child growth and adiposity: A longitudinal study.

Background: Exposure to polycyclic aromatic hydrocarbons (PAHs) during childhood has been associated with altered growth and adiposity in children. The effects of prenatal exposure to PAHs on developmental programming of growth and adiposity are still unknown.

Objective: To study the association of prenatal exposure to PAHs with early childhood growth and adiposity measures.

Associations of periconception dietary glycemic index and load with fertility in women and men: a study among couples in the general population.

Background: The dietary glycemic index (GI) and load (GL) reflect carbohydrate quality and quantity, potentially impacting fertility through modulation of insulin sensitivity and generation of oxidative stress. While fertility is influenced by both women and men, reproductive research often emphasizes maternal factors. We first examined periconception dietary intake in both women and male partners, and subsequent associations of dietary GI and GL with fecundability and subfertility.
