BACKGROUND Studies have shown that women use more health care services than
men. We used important independent variables, such as patient sociodemogra
phics and health status, to investigate gender differences in the use and c
osts of these services.
METHODS New adult patients (N = 509) were randomly assigned to primary care
physicians at a university medical center. Their; use of health care servi
ces and associated charges were monitored for 1 year of care, Self-reported
hearth status was measured using the Medical Outcomes Study Shea Form-36 (
SF 36). We controlled for health status, sociodemographic information, and
primary care physician specialty in the statistical analyses.
RESULTS Women had significantly lower self-reported health status and lower
mean education and income than men. Women had a significantly higher mean
number of visits to their primary care clinic and diagnostic services than
men. Mean charges for primary care, specialty care, emergency treatment, di
agnostic services, and annual total charges were all significantly higher f
or women than men; however, there were no differences for mean hospitalizat
ions or hospital charges. After controlling for health status, sociodemogra
phics, and clinic assignment, women still had higher medical charges for al
l categories of charges except hospitalizations.
CONCLUSIONS Women have higher medical care service utilization and higher a
ssociated charges than men. Although the appropriateness of these differenc
es was not determined, these findings have implications for health care.
