Time trends and risk factors for diabetes mellitus in cats presented to veterinary teaching hospitals

Abstract

Veterinary Medical Data Base records of cats with diabetes mellitus (DM) from 1970 through 1999 were reviewed to identify trends in hospital prevalence of DM and potential host risk factors. Hospital prevalence increased from eight cases per 10,000 in 1970 to 124 per 10,000 in 1999 (P < 0.001). Case fatality percent at first visit decreased from 40% to 10% (P < 0.001). Hospital prevalence increased in all age groups (P < 0.002). There was no apparent seasonal pattern in hospital prevalence. Significant risk factors included male gender, increasing age for both genders (P < 0.001), increasing weight for males (P < 0.001), and mixed vs pure breed for females (P = 0.006).
