M. Schootman et Lj. Fuortes, Breast and cervical carcinoma - The correlation of activity limitations and rurality with screening, disease incidence, and mortality, CANCER, 86(6), 1999, pp. 1087-1094
BACKGROUND. Although screening for breast and cervical carcinoma has been w
idely accepted as beneficial, specific segments of the population are not r
eceiving these services as frequently as recommended. The objective of this
study was to describe differences in breast and cervical screening prevale
nce among those with activity limitations and those residing in rural areas
. Disparities in the incidence rates of in situ breast carcinoma and cervic
al carcinoma, as well as mortality among rural and urban women, are also de
scribed.
METHODS, Data from the Iowa Behavioral Risk Factor Surveillance System (BRF
SS) and Iowa's Surveillance, Epidemiology, and End Results (SEER) were used
to determine the prevalence of screening and adverse outcomes among rural
populations. To describe the rural nature of counties, the authors used the
number of residents per square mile for each county and classified the res
ults into five groups. Mulitple logistic regression was used to determine t
he prevalence of screening among those with activity limitations and rural
residents.
RESULTS. Using the BRFSS, those with activity limitations and those residin
g in rural Iowa were less likely screened for breast or cervical carcinoma.
This translated into a lower in situ breast carcinoma incidence rate and a
higher invasive cervical carcinoma incidence rate among rural women relati
ve to their urban counterparts. No differences were found for mortality fro
m these cancers.
CONCLUSIONS. Lower screening prevalence among rural residents translated in
to adverse health outcomes. Interventions for increasing the frequency of s
creening are described. (C) 1999 American Cancer Society.
