The first national estimates on a variety of health indicators for the Hispanic and non-Hispanic populations of the United States are presented in this report, which consists largely of statistical tables containing data from the National Health Interview Surveys of 1978, 1979, and 1980. The primary focus of the report, however, is on four Hispanic population groups: Mexican Americans, mainland Puerto Ricans, Cuban Americans, and "other Hispanics." The topic areas include utilization of health services as measured by physician visits, dental visits, and hospitalizations; and illness and disability measures including incidence of acute conditions by condition group, days of restricted activity, days spent in bed and days missed from work because of illness and injury, and activity limitation associated with chronic conditions. The textual portions of the report highlight major findings, discuss sources and limitations of the data, and analyze general findings. Three appendices provide technical notes, definitions of terms, and questionnaire items and flash cards used in the survey. (KH)
