Abstract

The Avon Longitudinal Study of Parents and Children (ALSPAC) is a transgenerational prospective observational study investigating influences on health and development across the life course. It considers multiple genetic, epigenetic, biological, psychological, social and other environmental exposures in relation to a similarly diverse range of health, social and developmental outcomes. Recruitment sought to enroll pregnant women in the Bristol area of the UK during 1990-92; this was extended to include additional children eligible using the original enrollment definition up to the age of 18 years. The children from 14541 pregnancies were recruited in 1990-92, increasing to 15247 pregnancies by the age of 18 years. This cohort profile describes the index children of these pregnancies. Follow-up includes 59 questionnaires (4 weeks-18 years of age) and 9 clinical assessment visits (7-17 years of age). The resource comprises a wide range of phenotypic and environmental measures in addition to biological samples, genetic (DNA on 11343 children, genome-wide data on 8365 children, complete genome sequencing on 2000 children) and epigenetic (methylation sampling on 1000 children) information and linkage to health and administrative records. Data access is described in this article and is currently set up as a supported access resource. To date, over 700 peer-reviewed articles have been published using ALSPAC data.

  • ALSPAC is a birth cohort of 14,062 live births from women living in the former Avon County, southwest England, with expected delivery dates between April 1991 and December 1992.

    “The ALSPAC birth cohort follows children of 14 062 live births from women living in (the former) Avon County, a geographically defined region in southwest England, with expected dates of delivery between April 1991 and December 1992 (http://www.bristol.ac.uk/alspac).30”

    From Variant connective tissue (joint hypermobility) and its relevance to depression and anxiety in adolescents: a cohort-based case–control study (2022) · cites this paper as [30]

    In “Who is in the cohort?”, the paper confirms the Avon-area residence criterion and estimated delivery dates of 1 April 1991 to 31 December 1992. Its “ALSPAC recruitment rates” section reports 14,062 live-born children from pregnancies recruited antenatally, but says later recruitment brought the enrolled total to 14,775 live-born children. The claim does not qualify 14,062 as the initial recruitment group. (LLM, conf=0.88)

  • We tried to identify outcomes in the ALSPAC cohort that would be affected by confounders important in the relation of breastfeeding to later offspring outcomes but for which a biological/causal effect of breastfeeding was unlikely.

  • Individual participant data from the large UK Biobank and the Avon Longitudinal Study of Parents and Children are available to researchers globally at modest cost.

    “For example, individual participant data from the large UK Biobank (which currently has genotypic, phenotypic and clinical data in up to 500 000 adults76) and the Avon Longitudinal Study of Parents and Children (with very detailed data across three generations across their life course67,68) are available to researchers globally at modest cost”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
