Prevalence of cardiovascular diseases and associated risk factors in a rural black population of South Africa.

Background: To determine the prevalence and associated risk factors of cardiovascular diseases in a rural adult black population from Limpopo Province in South Africa.

Design: A cross-sectional study.

Methods: A sample of 1608 women and 498 men aged 30 years and above participated in the study.

Differences in cardiovascular disease mortality and major risk factors between districts in Oslo. An ecological analysis.

Background: The level of mortality from cardiovascular disease (CVD), coronary heart disease (CHD) and from all causes varies considerably within Oslo. The purpose of this study was to examine these differences according to cardiovascular risk factors and socioeconomic variables at the district level.

Methods: Total mortality rates and cardiovascular mortality rates for subjects aged 45-74 years in 1991-1995, and their relationship to cardiovascular risk factors and socioeconomic indicators in the 25 districts of Oslo were studied.

Epidemiology of hip fractures in Oslo, Norway.

The incidence of hip fractures in Oslo has shown a secular increase during the past decades. The main aims of the present study were to report the current incidence of hip fractures in Oslo and to determine whether there is a seasonal variation in the occurrence of fractures. Using the electronic diagnosis registers and the lists of the operating theater for the hospitals in Oslo with somatic care, all patients with ICD-9 code 820.

More postoperative femoral fractures with the Gamma nail than the sliding screw plate in the treatment of trochanteric fractures.

Despite several studies showing a higher incidence of peri-implant femoral fractures with the Gamma nail than with a sliding screw plate (SSP), the Gamma nail has remained the standard implant for trochanteric fractures in many hospitals. We recorded 921 trochanteric fractures in the city of Oslo during 2 years and compared the reoperation frequency in patients treated with the Gamma nail (n 379) and SSP (n 542). The distribution of age and gender in the two treatment groups was the same.

Adipose tissue fatty acids and risk of myocardial infarction--a case-control study.

Objectives: To study the association between content in adipose tissue of very long-chain n-3 fatty acids, trans fatty acids, linoleic acid and alpha-linolenic acid and risk of a first myocardial infarction.

Design And Subjects: A case-control design among 100 patients and 98 population controls both men and postmenopausal women, age 45-75 y. Adipose tissue fatty acids were determined by gas-liquid chromatography.
