ALGAE is an automated protocol to assess historical exposure to air pollutants for
members of longitudinal cohort studies. It was developed as part of a research
project between the Small Area Health Statistics
Unit(SAHSU), Imperial College London and
the Avon Longitudinal Study of Parents
Initially designed to support an environmental epidemiological study on air pollution exposure during pregnancy and respiratory health effects in children, the protocol has since been developed into a generic solution which can be adapted to investigate different life stages and environmental pollutants. ALGAE is intended as a generic and reusable exposure study protocol to:
Initially ALGAE was designed to support a study on "Effects of early life exposure to particles on respiratory health through childhood and adolescence". It has since been developed into a generic solution which can be adapted to different cohort studies, life stages, health outcomes and environmental exposures.

To support the protocol we have developed test cases using the SAHSU-ALSPAC as example.. The code can be modified to include different life stages, environmental pollutants or covariates. Please see our sections on adapting the code.
