The Panuara Formation at Cobblers Creek near Orange, New South Wales, Australia has yielded a graptolite-brachiopod fauna assigned to the sherrardae sub-Biozone (late Wenlock: Early Silurian). The sherrardae sub-Biozone as defined here is equivalent to the praedeubeli subBiozone, and is the lowest part of the ludensis Biozone. The ludensis Biozone is reappraised following restudy of the type specimens of Monograptus ludensis, which are shown to exhibit growth stages from the deubeli to the gerhardi condition. The graptolite fauna consists of Gothograptus chainos Lenz, G. marsupium Lenz, Pristiograptus jaegeri Holland, Rickards & Warren, Pristiograptus dubius (Suess), Monograptus ludensis (Murchison), Monograptus moorsi n ...

Objective. To determine the prevalence of diabetes and its associated risk factors in elderly coloured South Africans. Research design. Cross-sectional analytical study. Methods. A random sample of 200 non-institutionalised coloured (mixed ancestry) subjects aged 65 years of age, resident in urban Cape Town, was drawn by means of a two-stage cluster design. The survey procedure included an oral glucose tolerance test, anthropometric measurements, and physical activity and alcohol intake assessments. Results. The prevalence of diabetes was 28.7% (95% Cl 21.7 - 35.7%), 25.7% in men and 30.3% in women. The prevalence of impaired glucose tolerance was ...

Physical Activity, Change In Blood Pressure And Predictors Of Mortality In Older South Africans - A 2-Year Follow-Up Study, Karen E. Charlton, Estelle V. Lambert, Judith Kreft

Faculty of Science, Medicine and Health - Papers: part A

Objective. A 2-year follow-up study of a cohort of 200 historically disadvantaged older South Africans was conducted to: (i) characterise current levels of habitual physical activity; (ii) relate physical activity to current risk factors for chronic disease; and (iii) identify risk factors associated with 2-year mortaJity. The baseline sample, drawn in 1993, was found to have a high prevalence of hypertension (71.7%). Research design. Retrospective cohort study. Methods. A baseline sample of 200 persons aged ;:;.. 65 years, resident in the Cape Peninsula, was randomly drawn by means of a two-stage cluster design. Baseline measurements included: anthropometry, waist/hip ratio ...
