  • Main aim of cohort
    EHL investigates the longitudinal influence of gestational and early-life environmental and behavioural exposures on the health of offspring. Its main foci are: the development of overweight and obesity and their attendant co-morbidities; maternal mental health; and childhood unintentional injuries. Exposures being investigated are those that occur antenatally (parental body composition, blood glucose, blood pressure, diet and physical activity, family circumstances and household/neighbourhood conditions) and post-natally (birth outcomes, early feeding/weaning/diet, growth and development, sleep patterns, diet, physical activity, childcare, and ongoing/changing family circumstances and household/neighbourhood conditions).

    Recruited number of:
    420 children / 420 mothers / 0 fathers / 0 grand parents / 0 other family members

    Approximate proportion of source population included
    20

    Source population
    Region-based

Comments and ideas
The major strength of EHL is its use of data linkage to conduct and support high quality research. EHL has a unique study component in linking to electronically-held, person-based, routinely collected and anonymised health and social care data. Benefits of this unique methodology include reducing participant burden for the longitudinal follow-up of outcomes, minimising sample attrition, and enabling the modelling of findings to create a total-population cohort.
