Physical and mental health encompasses a wide range of health outcomes and can be measured in many different ways. The Indicators in this Topic were chosen to reflect important public health issues that are not captured in other Topics in the Public Health Theme. The first two Indicators measure visits to the emergency department for severe mental illness and for substance abuse. The third Indicator measures new HIV diagnoses in Alameda County. In all three of these Indicators, the greatest disparities are between African American and Asian Oaklanders.
