  • ALSPAC

    Avon Longitudinal Study of Parents and Children
    Based at the University of Bristol, the Avon Longitudinal Study of Parents and Children (ALSPAC), also known as Children of the 90s, is a world-leading birth cohort study. Between April 1991 and December 1992 we recruited more than 14,000 pregnant women into the study and these women (some of whom had two pregnancies or multiple births during the recruitment period), the children arising from the pregnancy, and their partners have been followed up intensively over two decades. We are the most detailed study of its kind in the world and we provide the international research community with a rich resource for the study of the environmental and genetic factors that affect a person’s health and development. Through our research we aim to inform policy and practices that will provide a better life for future generations.

  • CONSTANCES

    Cohorte des Consultants des Centres d’Examens de Santé

  • DFBC

    Dutch Famine Birth Cohort study
    The cohort was set up to investigate the effects of acute maternal undernutrition during specific stages of gestation on the offspring’s adult health. The main outcomes of interest of the DFBC are chronic cardiovascular and metabolic diseases, ageing and mental health. Differences in various outcomes have been found between participants exposed to famine and unexposed participants. Although statistically significant, these differences are not very large, therefore adjusting for exposure group enables researchers to use DFBC data in pooled analyses.

  • EDEN

    Study on the pre and early postnatal determinants of child health and development
    The EDEN study is a French bicentric generalist cohort study (Heude et al. IJE 2016). Pregnant women were invited to participate during their prenatal visit, before the 24th week of amenorrhea, in the obstetrics and gynecology departments of the Poitiers and Nancy university hospitals. Recruitment took place from February 2003 to January 2006. The exclusion criteria were: twin pregnancy, diagnosis of insulin-dependent diabetes, inability to speak and read French, intention to move from the region within three years of inclusion . Among the women invited, 53% agreed to participate (n = 2,002). Detailed information on phenotypes and exposures were collected through questionnaires from pregnancy until 8 years and through clinical examinations of the mother (at 24 weeks of amenorrhoea, at delivery and 5–6 years after delivery) and the child (at birth and 1, 3 and 5–6 years, including cognitive assessments at 3 and 5–6 years). At 5–6 years, 1255 children were still followed up.

  • ELFE

    Etude Longitudinale Française depuis l'Enfance" (French longitudinal study of children)
    ELFE is the first French national birth cohort. Its objective is to study determinants of the development, health and socialization of children from birth to adulthood through a multidisciplinary approach. A total of 18 329 children were recruited at birth in a random sample of maternity units in metropolitan France during 25 selected days of 2011 spread over the year. Participation rates at the age 2-month, 1- and 2-year and 3.5-year parental interviews were 92%, 86%, 82% and 80%, respectively, of contacted participants. The ELFE has an open-data policy after an 18-month exclusivity period following each release of new data. The data-access policy, study protocols, questionnaires and data catalogue can be found online: [https://www.ELFE-france.fr/en/].

  • ELIPA

    Foods for weight management
    This study aimed to investigate factors associated with weight management, especially whether satiety value of food as a part of a weight-maintenance diet would affect self-regulation of food intake and weight management. All participants underwent a 7-week very-low-energy-diet and were thereafter randomized into higher- and lower-satiety food groups during a 24-week weight maintenance period. As a part of weight maintenance diet, the groups consumed food products that differed in their pre-determined satiety value and macronutrient composition.

  • FEF

    Fibrefects - Grain fibre modification for gut-mediated health effects

  • FinnGeDi

    Finnish Gestational Diabetes Study

  • GenR

    The Generation R Study
    The Generation R Study is a population-based prospective cohort study from fetal life until adulthood and is conducted in Rotterdam, the second largest city in the Netherlands. The study is designed to identify early environmental and genetic causes and causal pathways leading to normal and abnormal growth, development and health from fetal life, childhood and young adulthood. This multidisciplinary study focuses on several health outcomes including behaviour and cognition, body composition, eye development, growth, hearing, heart and vascular development, infectious disease and immunity, oral health and facial growth, respiratory health, allergy and skin disorders of children and their parents. Main exposures of interest include environmental, endocrine, genomic (genetic, epigenetic, microbiome), lifestyle related, nutritional and socio-demographic determinants. The Generation R study enrolled 9,153 mothers with a delivery date from April 2002 until January 2006, who participated with a total of 9,778 pregnancies in the study from which 9,901 children were expected to be born; the mothers gave birth to 9,749 live born children.

  • GenR Next

    Generation R Next
    The Generation R Next Study is a population-based cohort study from preconception onwards. In total, about 3600 women are being included in the period 2017-2021. Of all included couples, about 30% is included during the preconception, about 60% during the first trimester of pregnancy and about 10% in the third trimester of pregnancy.
