It is uniquely equipped to follow changes in health and well-being across the lifespan, what affects this, how certain factors work across generations and how changes in society affect the health and well-being of families going through similar events 30 years alspac data.

Postnatal depression which persists beyond six months after birth and is severe, increases the risk of children exhibiting behavioural problems, achieving lower GCSE mathematics grades at 16 years and having depression at 18 years of age. A major international study has pinpointed more than genetic risk factors that explain why some people suffer from asthma, hay fever and eczema.

App version: 0. You can find full information about the cohort here. For more than two decades clinic and questionnaire data has been collected from the participants. This search tool is a quick and abridged version of a much more extensive data dictionary. You can find a lot more detail about these data here. Use this website to search through the variables, obtain their identifiers and the number of records with that measure. You can use download lists of selected variables. For direct users, this can be used to extract variables directly. Alternatively, add this list to your data request form to specify the data that you require.

The main aim of ALSPAC is to understand how genetic and environmental factors influence the health and development of parents and children. During initial recruitment all pregnant women who were resident in the former county of Avon, an area around Bristol in South West England, with an expected delivery date between 1 st April and 31 st December were invited to participate [88, 89]. When the oldest children were approximately 7 years old, additional eligible participants were invited to join the study. Therefore, the total sample for the child-based data collected at 7 years is 15, with 14, alive at 1 year of age. All of these children have been regularly followed up using parental and self-completion questionnaires, medical records, educational and clinical assessment and through linkage. Compared with the whole of Great Britain in , the population of mothers with infants under one year of age resident in Avon were more likely to live in owner occupied accommodation, to have a car and less likely to have one or more persons per room and be non-white [90].

Please read the ALSPAC access policy 19 which describes the process of accessing the data and samples in detail, and outlines the costs associated with doing so. You may also find it useful to browse our fully searchable research proposals database 20 , which lists all research projects that have been approved since April You will receive a response within 10 working days to advise you whether your proposal has been approved. Please note that a standard COVID dataset will be made available at no charge see description below ; however, costs for required paperwork and any bespoke datasets required additional variables will apply.

The second version of our manuscript takes into account the constructive comments made by the reviewers. In particular, we have provided detail in the introduction explaining what the UK lockdown entailed and we have emphasised the issues with applying the Menni algorithm to symptom data collected in in both the results and discussion. See the authors' detailed response to the review by Sarah Crozier and Janis Baird. There is marked heterogeneity in disease prevalence, severity and outcome both within and across populations. In part, this may be driven by the interplay between environmental, social and host factors such as age and pre-existing comorbidities which predispose or protect against infection or modify disease outcomes. Understanding this interplay requires studies with detailed environmental, health, lifestyle, and biological data — ideally measured within the context of longitudinal data and with prospective collection opportunities. Alongside the health implications of the virus itself, the response to the pandemic is likely to affect health and wellbeing. Mitigation measures have resulted in far-reaching changes to daily activity which are likely to have an impact on nearly all aspects of work, family life, recreation and, potentially, health.

Alive at 1 year of age mz Since folate is an important nutrient to prevent neural tube defects, this finding strengthens the argument for fortification of stable foods with folate.

We have a vast amount of biological samples and phenotypic, environmental, genetic and linkage data gathered from different cohort groups over the past 30 years. There are several ways you can explore this resource.

These FFQ need to be used together to estimate energy and nutrient intakes and dietary patterns. Int J Epidemiol. If there is anything you cannot find, please consult the data dictionary or variables catalog. ALSPAC was specifically designed to understand the ways in which genetic and environmental factors interact to influence health, behaviour, and development across the lifespan. Table 2. Additional information. A large amount of information has been derived from our biological resources. There are also a number of minor typos to be addressed during the final editorial process. To assist researchers in doing so, we created the mzl variable indicating which pregnancies to keep and which to drop, in order to reduce the dataset to one observation per mother Table 2. G0 mothers with two or more enrolled pregnancies In the enrolled sample, four mothers had three eligible pregnancies — in each case one of these pregnancies was either never formally enrolled or, if enrolled, had no data associated with it.
