National Prevalence of Diabetes and Barriers to Care Among US Farmworkers and Association With Migrant Worker Status

OBJECTIVE To quantify the prevalence of diabetes and barriers to care among U.S. migrant farmworkers (i.e., those who travel from their permanent residence for seasonal farmwork). RESEARCH DESIGN AND METHODS Age-adjusted prevalence of self-reported diabetes and barriers to care were calculated among adult U.S. farmworkers from 2008 to 2017 National Agricultural Workers Surveys. RESULTS Among 16,913 farmworkers, 30.7% reported one or more barriers to care, most often due to cost. Age-adjusted self-reported prevalence of diabetes was 13.51% (95% CI 10.0-17.1) among migrant farmworkers and 10.8% (95% CI 9.0-12.6) among nonmigrant farmworkers with access to health care. Migrant farmworkers without recent health care had 83% lower odds of reporting known diabetes (adjusted odds ratio 0.17; 95% CI 0.06-0.54) compared with nonmigrant farmworkers, likely because of poor health care access and/or a healthy worker effect. CONCLUSIONS Many migrant farmworkers face barriers to care, which may lead to significant underdiagnosis of diabetes in this vulnerable population.
