Surveillance of Mortality and Morbidity in US Workers

Project: Research project

Project Details


DESCRIPTION (provided by applicant): The databases available to examine
national patterns and trends of US worker health and safety are out dated, and
in general, incomplete. The National Health Interview Survey (NHIS), a
multipurpose household survey of the US civilian noninstitutionalized
population conducted annually since 1957 by the National Center for Health
Statistics (NCHS) of the Centers for Disease Control and Prevention (CDC), has
collected demographic, health, and employment data on over 450,000 US workers
aged 18 years and older in a probability sampling of the entire US population,
with a Mortality Follow Up with cause of death from 1986 through 1995.
Therefore, the NHIS database allows for longitudinal analysis of mortality data
as a retrospective cohort study, as well as cross-sectional and trend analysis
of the aggregate morbidity data collected annually representative sample of all
US workers for the past 2 decades.
Using this uniquely representative and large database of the NHIS 1986-94
surveys with Mortality Follow-Up, the objectives of this proposed study are to
evaluate the time trends for morbidity, and the longitudinal mortality
associated with industry and occupation for the US worker. After assembling the
cohort of employed persons aged 18 and older, the Investigators will examine
the cause specific mortality and reported health and disability as summarized
data for all annual NHIS interviews from 1986-1994, as well as the morbidity
time trends, by industry and occupation. Hypotheses have been generated based
on the historical literature; these hypotheses can be tested not only in terms
of specific industry/occupational subgroups, but also in subgroups determined
by important confounding variables such as age, gender, race/ethnic,
socio-economic status, and geographic region (depending on the subgroup sample
size). The costs of injury and disease in terms of lost work time and the use
of medical services can be evaluated by specific industry/occupational
subgroups; cause-specific mortality by industry/occupational subgroups, as well
as by the same confounding variables, will also be determined.
The investigators propose to create 2 Study Monographs, one on Morbidity and
one on Mortality, to be made publically available on a linked Study Website so
that researchers and the general occupational health community can use these
data to compare to prior studies, to develop new research hypotheses, and to
use the data as a surveillance tool to evaluate time trends and occupational
disease in the US for the past 2 decades in both genders and in a variety of
ace-ethnic subpopulations. This study proposal satisfies at least 3 NIOSH
research priority areas (NORA): 1) surveillance research methods providing
unique mortality and morbidity data on the entire US workforce; 2) unique
mortality and morbidity data on older, race-ethnic, lower socio-economic and
gender-specific worker subpopulations in the US; and 3) unique data on social
and economic costs of workplace disease and injury. In addition this
application is responsive to Program Announcement "Occupational Safety and
Health Research (PA-99-143J.
