The benefits of combining HBM and health data – results from HBM4EU – 28 April – 2:35 pm CEST

Combining human biomonitoring (HBM) data with health data allows to study possible associations between environmental exposures and their health effects. It is important to have a wide information about health determinants, including environmental exposures and more traditional socio-demographic and biological determinates, to obtain a holistic understanding of the risks.

Cross-sectional HBM studies and health surveys use similar infrastructure and have same target group, general population or a specific population sub-group(s). Therefore, combining these two study types is technically possible and cost-effective. Combined surveys will provide wider information source, often larger sample size, use of already existing survey infrastructure, and better publicity.

In some countries, health data can also be obtained through linking HBM studies to administrative health registers such as hospitalization data or mortality data. This is a cost-effective way to collect health information with good coverage. This allows transfer of cross-sectional studies into cohorts with follow-up information on health outcomes.
