Abstract
OBJECTIVE —Diabetes-related lower-extremity amputation (LEA) rates are elevated in blacks compared with whites in the U.S., but are
lower in African Caribbeans in the U.K., whereas anecdotal reports suggest high rates in the Caribbean. We aimed to establish
the incidence and risk factors for diabetes-related LEA in a Caribbean population.
RESEARCH DESIGN AND METHODS —We conducted an incident and prospective case-control study of case patients (individuals with diabetes having a LEA) and
community-based control subjects (individuals with diabetes without a LEA) in Barbados, West Indies. Participants completed
an interview and examination of risk factors for amputation, including footwear use.
RESULTS —The overall 1-year incidence of LEA ( n = 223) was 173 per 10 5 population and 936 per 10 5 population with diabetes (557 per 10 5 for minor amputation and 379 per 10 5 for major amputation). Women had higher amputation rates than those reported in the Global Lower Extremity Amputation Study,
apart from the U.S. Navajo population. Independent risk factors for all diabetes-related LEAs were poor footwear (odds ratio
[OR] 2.71 [95% CI 1.23–5.97]), elevated GHb (1.40 per percent increase [1.26–1.57]), peripheral neuropathy (1.05 per volt
increase [1.03–1.08]), and peripheral vascular disease.
CONCLUSIONS —Diabetes LEA rates in Barbados are among the highest in the world. Inadequate footwear independently tripled amputation risk.
Education of professionals and patients, particularly about footwear and foot care, coupled with improved diabetes clinical
care, is key to reducing amputation risk in this population.
