Rm. Brackbill et al., PREVALENCE OF CHRONIC DISEASES AND IMPAIRMENTS AMONG US FARMERS, 1986-1990, American journal of epidemiology, 139(11), 1994, pp. 1055-1065
Farmers in the United States suffer disproportionately from certain ch
ronic diseases and impairments. This analysis estimated the prevalence
of selected diseases among farmers and compared these rates with thos
e for other US workers. Five years (1986-1990) of National Health Inte
rview Survey data on white male workers were combined to provide a bas
is for estimating the prevalence of selected conditions and impairment
s among this subgroup. Crude prevalence rates were significantly eleva
ted for farmers compared with other workers for cardiovascular disease
s, arthritis, skin cancer, hearing loss, and amputations. These elevat
ions persisted when farmers were compared with blue-collar workers. Th
e crude prevalence of orthopedic impairments and chronic respiratory d
iseases was not elevated among farmers, but the age-adjusted prevalenc
e ratios for cardiovascular diseases, arthritis, and amputations were
significantly elevated for farmers as compared with other workers. The
prevalence of hearing loss was significantly higher only for farmers
older than 65 years. This method of pooling data holds promise for stu
dying disease rates in other small segments of the US population.
