XXXX in blacks--an established problem.

@entity1 @entity66 @entity3657 @entity101 @entity75 @entity6 @entity3468 @entity439 @entity299 @entity432 @entity731 @entity62
Records of black (predominantly Zulu), Indian and white @entity1 admitted to hospital for elective evaluation of chronic @entity3657 over a 2-year interval were examined. The @entity75 encountered in all three groups was @entity731 , although @entity3468 occurred more frequently in blacks. While @entity731 of the lower extremities showed minor differences in distribution in the three groups, @entity439 was more frequent in the @entity62 . @entity432 was also less prevalent among blacks. Age and sex distribution was similar. In a subset of @entity1 , matched for age, with aorto-iliac occlusive disease blacks had a statistically significantly lower incidence of @entity299 , @entity66 and @entity101 than whites or Indians; and smoked less. @entity6 had a significantly higher incidence in Indians. Within the same group of @entity1 , blacks tended to present at a more advanced stage in the natural history of the disease. However, early and medium-term results of aortobifemoral bypass are not significantly different from those in whites or Indians. @entity731 , contrary to popular belief, is a well-established clinical problem in the black population in Natal.
