What is the Los Angeles County Health Survey? to top
The Los Angeles County Health Survey (LACHS) is a population-based telephone survey that collects information on socio-demographic characteristics, health status, health behaviors, and access to health services among adults and children in Los Angeles County. It was conducted in 1997, 1999-2000, 2002-03, 2005 and again in 2007.
 


Why is it important? to top
Population-based data are essential for public health assessment, planning, developing and targeting health resources, and for evaluating changes in health and factors that influence health over time. Data from the LACHS are not available from other private or public sources. Data from the LACHS complement other essential public health data sources such as vital records, disease surveillance, hospital discharge, and other clinically- and administratively-based information.
 


How are survey data used? to top
Data from the survey are used throughout Los Angeles County by numerous public and private institutions to measure and track trends in critical areas of health. These areas include access to health care (e.g., health insurance coverage, barriers to receipt of services, need for essential services, use of DHS services), health status (e.g., chronic diseases and conditions such as hypertension, diabetes, overweight and obesity) and key health behaviors (e.g., smoking, alcohol use, physical activity, high risk sexual practices). The data are essential to support planning, funding development, public policy and advocacy, targeting resources, and for ongoing evaluation of changes in health outcomes. In addition, funding agencies often require population-based data as part of application or evaluation processes.
 


Who uses the survey data? to top
The data are used extensively throughout the Department of Health Services as well as by other County Departments (DPSS, CAO), private organizations such as the Children's Planning Council, United Way, and the Proposition 10 Commission, by researchers in universities and other institutions, hospitals and health care providers, and community-based agencies. For example, the data were used to develop proposals to expand public health care coverage for children and adults in the county, and in community health assessments (as required by SB697) by hospitals throughout the county.
 


How are the results of the survey reported? to top
The results of the LACHS are disseminated through departmental and other publications, media releases, on the Internet, in presentations, and in peer-reviewed papers. In addition, LACHS results are analyzed and provided by special request.
