Of Special Interest

Asthma is the most common chronic disease among children and one of the leading causes of school absenteeism in the U.S. today, where the overall prevalence rate has increased 70% from 1980 to 1994.

The California Environmental Health Tracking Program (CEHTP) is implementing a 4-year pilot project that will serve as a "road test" for elements of an environmental public health tracking system. 

Scope of the Project

This project is demonstrating how utilization of existing data can contribute to public knowledge while maintaining data confidentiality.  To locate "hot spots" of disease and explore possible relationships with environmental hazards, we are using data from 2001 for Alameda County for:

Preterm birth and term low birthweight  (Source: California Center for Health Statistics)

Asthma-related health care use  (Sources: Kaiser Permanente of Northern California and Medical Care Statistics Section of the California Department of Health Services)

Traffic pollution  (Sources: CalTrans and the California Air Resource Board)

Project Components

Partnerships for Data Sharing- We are partnering with Kaiser Permanente of Northern California and DHS Medical Care Statistics Section to access administrative data in order to describe the burden of asthma in communities within Alameda County.

Data Processing and Analysis- We are exploring and developing methods to effectively present information visually.  This includes the creation of high resolution smoothed-surface maps.

Stakeholder Participation- We are partnering with the Pacific Institute to coordinate and convene a stakeholder group to provide input and feedback on the project methods, findings, and dissemination plan. Members include representatives from CBOs, NGOs, health providers, and local agencies. Click here to learn more >>

Dissemination Plan- We are partnering with InfoOakland to develop and display project findings in a countywide, interactive visual user interface.  InfoOakland also provides trainings and direct assistance to communities.  For more information, go to

Intended Outcomes

Identify communities with elevated risk for asthma, preterm birth, or low birthweight and assess their exposure to traffic pollution.

Increase the capacity to examine possible connections between asthma, preterm birth, and low birthweight with exposure to pollution caused by automobile and truck traffic.

Explore various methods of measuring asthma in populations.

Assess the benefits, limitations, and costs of this type of environmental health tracking system and explore how this approach may be applied to other diseases and environmental hazards throughout California.

Provide communities with new information to address health concerns regarding traffic-related exposures.
