| TECHNICAL NOTES/ DATA SOURCES - Maternal and Child Health/ Population Mortality
· The birth and death data that appear in this report was
collected at the county level, then cleaned and reallocated by the California Department
of Health Services (DHS), Office of Vital Records and Statistics.
· County population data and projections were provided by
a California Department of Finance (DOF) 1997 publications for aggregate numbers and by
DOF 1996 publications for ethnic-specific proportions. Age proportions for age-adjustment
were calculated by applying age-group proportions from the old (1993) DOF population
summaries to the newer aggregate numbers.
- Infectious Diseases
· Local incidence data on most infectious diseases was
provided by the Automated Vital Statistics System (AVSS) as run by the San Mateo County
Disease Control and Prevention Unit (DCPU.). State and national disease incidence figures
were taken from CDC-MMWR Summaries of Notifiable Diseases for the various years
1990 - 1996 and from CD Summaries published by the DHS Division of Communicable Disease
Control.
· The tuberculosis data came from the Tuberculosis Control
Branch of DHS. Original case definitions for measles, syphilis and tuberculosis are
contained in the Morbidity and Mortality Weekly Report (MMWR), Vol. 39, Number
RR-13,Oct. 19, 1990.
· AIDS case data was received from the AIDS Surveillance
Section of the DCPU. The original case definition for AIDS is contained in the Morbidity
and Mortality Weekly Report (MMWR), Supplement 1S, Vol. 367, Aug. 14th,
1987. This definition was revised in 1993, and this revised classification system and the
accompanying expanded definition for surveillance can be found in the MMWR, Vol.
41, Number RR-17, Dec. 18, 1992.
Age-Adjusted Rates
The age adjusted rates that appear in this report were calculated by the direct method,
in which a standard age distribution is chosen and the age specific death or incidence
rates for the group of interest are weighted according to that standard.
Data Definitions
· The Kessner Index used to determine adequate rates of
prenatal care was calculated using the Institute of Medicine Three-Factor Prenatal Care
Index. The index uses gestational age, number of prenatal visits and trimester prenatal
care began to determine adequacy of that care. A complete description of this methodology
can be found in the following publication:
Institute of Medicine, Contrasts in Health Status - Vol. 1, "Infant
Death: An Analysis by Maternal Risk and Health Care." David Kessner, Project
Director, published by the National Academy of Sciences, Washington, DC, 1973, p. 58-60.
· Adolescent births were
classified as those occurring to mothers who were less than or equal to 17 years of age at
date of delivery.
· Low birth weight is defined as less than 2500 grams at
birth.
· Late/no prenatal care refers to initiation of prenatal
care after the first trimester or not at all.
· Mortality data and hospital discharge data were
categorized according to standard diagnostic categories contained in the International
Classification of Diseases, Ninth Revision (ICD-9) as follows:
Race/Ethnicity Categories
The race/ethnicity divisions used in the report are mutually exclusive and are
consistent with those used by the State Census Data Center. Birth certificate data –
that providing the basis of the included maternal and child health indicators –
allows further differentiation among Asians, Filipinos and Pacific Islanders.
