California Adolescent Health Data Set

The California Adolescent Health Data Set (Data Set) is a collection of California‐wide and county‐specific
data about the health status of adolescents. The compiled data is contained in a single Excel
spreadsheet, making it easy to access data on over 50 adolescent health indicators, such as physical,
sexual/reproductive, or mental health.  The Data Set spreadsheet is made up of several worksheets that
enable the user to view raw data or display charts for each indicator.  Data can be viewed for specific
topics or from specific data sources.

Uses for the California Adolescent Health Data Set

Adolescent health providers and professionals need data to inform their work, but data on adolescent
health can be difficult or time consuming to retrieve.  Therefore, the Data Set is designed to be
accessible, practical, and easy to use for health department staff, providers, policy makers, community
leaders, educators, and advocates.
The Data Set is a resource for the following types of uses:

Education

•    Educate staff and/or potential stakeholders about adolescent health status in a specific county.
•    Educate and empower adolescents participating in youth development, school or health
programs by helping them to interpret data on adolescent health in their own communities.

Assessment and Evaluation

•    Conduct an assessment of adolescent health status for a specific county.
•    Use indicators as population‐level baseline measures for needs assessments or evaluations.
•    Compare a county with the state overall or other counties with similar characteristics.

Program development or implementation

•    Describe adolescent health issues to policy makers or program administrators and make the
case to address a specific issue.
•    Support funding proposals or budget justifications with data.
•    Guide and support collaborations among partners to discuss adolescent health promotion
strategies and outcomes.

Advocacy

•    Provide community members and policy makers with information to support their advocacy
efforts.

Health Indicators

The health indicators included in the Data Set reflect those measured by Healthy People 2010’s 21
Critical Health Objectives for Adolescents and Young Adults.  In addition, available California‐specific
data about youth resilience, demographics, and health behaviors is included.

A total of 54 indicators are included within the following topics:

  • Chronic Illness
  • Mental Health
  • Resilience
  •    Substance Use
  • Injury
  • Nutrition/Physical Activity
  • School Performance
  •    Violence
  • Juvenile Justice
  • Population & Socio-Demographics
  • Sexual Health

 

Data Sources, Criteria, and Methods

Data for each indicator was extracted and compiled from public access databases, including information from vital records, hospital records, administrative data, and statewide surveys. Some of the primary sources were: the California Department of Public Health, California Department of Education, California Health Interview Survey (CHIS), and California Healthy Kids Survey (CHKS). The raw data from these sources were collected and calculated in different ways. Data may be derived from population surveys (e.g., demographic numbers from the Census), medical records (e.g., injury data from hospital records), or representative sample surveys (e.g., measures of risk behaviors). For a complete list of sources, please see the Source List in the guide to the Data Set. To be included, data had to be available at the county level, collected over time, and available for individuals within the age range of 10-24. In addition, data on each indicator had to provide a statistically stable population level estimate. For example, for counties with small populations, there may not be a sufficient number of respondents to a survey to calculate an accurate measure for the adolescent population in that county. In such cases, counties are grouped together. Where applicable, 95% confidence intervals are included for data points. The confidence intervals take into account error in measurement to provide a statistically accurate estimate of the possible range of values for a specific indicator.

 

Limitations

This Data Set is limited to data that currently exist about California adolescents and the age ranges represented. Some important health indicators that are not available from the current data include measures of oral health in adolescents, mental health access, immunization, disability, and environmental health. Data on subpopulations of adolescents, such as youth who are in foster care, out-of-school, LGBTQI, or homeless, are also lacking. Data from each source have limitations related to their collection methods. Who is included, what, and how questions are asked, and the approach to collecting the data (e.g., telephone or in-person survey) influence the results and can lead to some potential bias in the results. In addition, there can be a long delay between when data is collected and when it becomes available for public use.
