Geographic and Temporal Patterns of Screening for Breast, Cervical, and Colorectal Cancer in the US, 1997-2019.

ABSTRACT:

Importance

Despite guidelines and recommendations, cancer screening remains low and variable across geographic and sociodemographic groups, contributing to persisting disparities.

Objective

To analyze geographic and temporal patterns of county-level cancer screening prevalence for breast, cervical, and colorectal cancer over a 22-year period in the US and examine sociodemographic factors associated with screening clusters.

Design, setting, and participants

This cross-sectional study used an ecological panel design using county-level screening prevalence as the unit of analysis. Data were collected from US mainland counties (ie, excluding Alaska, Hawaii, and Puerto Rico) from 1997 to 2019, with prevalence estimated over 3- to 5-year periods. Data were analyzed from 202
