“…The mean ages and peak prevalence for stroke in developed countries have been reported to be higher than those of developing countries 13. Also, the male preponderance of stroke noted in our study is comparable to data obtained in Sub-Saharan African studies 3,6,11,16…”

BackgroundThe prevalence and incidence of stroke vary from community to community worldwide. Nonetheless, not much is known about the current epidemiology of stroke in rural Nigeria and indeed Africa.MethodsWe carried out a two-phase door-to-door survey in a rural, predominantly low-income, community in Anambra, Southeastern Nigeria. We used a modified World Health Organization (WHO) protocol for detecting neurological diseases in the first phase, and a stroke-specific questionnaire and neurological examination in the second phase. An equal number of sex- and age-matched stroke-negative subjects were examined.ResultsWe identified ten stroke subjects in the study. The crude prevalence of stroke in rural Nigeria was 1.63 (95% confidence interval [CI] 0.78–3.00) per 1,000 population. The crude prevalence of stroke in males was 1.99 (95% CI 0.73–4.33) per 1,000, while that for females was 1.28 (95% CI 0.35–3.28) per 1,000 population. The peak age-specific prevalence of stroke was 12.08 (95% CI 3.92–28.19) per 1,000, while after adjustment to WHO world population, the peak was 1.0 (95% CI 0.33–2.33) per 1,000.ConclusionThe prevalence of stroke was found to be higher than previously documented in rural Nigeria, with a slightly higher prevalence in males than females. This is, however, comparable to data from rural Africa.

“…In a rural South African survey, the age-adjusted prevalence among populations aged above 15 years was higher than ours (3.3 versus 1.90 per 1,000) 11. Also, an Asian study in urban Singapore reported a higher age-adjusted prevalence than ours in the population aged 65 years and above (6.31 versus 0.40 per 1,000) 12.…”

“…In Nigeria, a prevalence of 1.1/1,000 was reported out of a population of 13,127 people aged more than 15 years. In South Africa, the Stroke Prevention Initiative reported 2.4–3.0 stroke cases per 1,000 individuals in a population of 42,378 persons aged over 15 years [22]. The prevalence of stroke in Benin is also higher than that reported outside the African continent in South America [23], India [24] or Arabic countries [25].…”

Background: Little is known about the burden of stroke in sub-Saharan Africa that may increase with the ongoing demographic and socioeconomic transition. This study aims to assess the prevalence of stroke, its related disability rate and consequences in the quality of daily life in an urban door- to-door survey in Cotonou, Benin. Methods: A three-phase door-to-door study was performed in two districts of Cotonou with a broad range of socioeconomic income. A population of 15,155 individuals aged ≧15 years was evaluated. The first phase consisted in screening of stroke in the population using the modified WHO questionnaire, the second phase included the medical evaluation of all suspected cases, and in the third phase the diagnosis of stroke was confirmed by CT scan evaluation. Results: Out of 15,155 subjects, 321 cases were identified as possible stroke cases. The diagnosis was confirmed in 70 cases. The crude prevalence of stroke was thus estimated to be 4.6/1,000 (8.7/1,000 and 7.7/1,000 adjusted to the WHO and SEGI World Population). The mean age of the patients at onset was 56 ± 13 years. Sixty percent of stroke survivors had a Rankin score ≧2, and CT scan was found abnormal in 90.0% of them. Conclusion: The stroke prevalence in urban areas of Cotonou is higher than that reported in other sub-Saharan countries, and the majority of stroke survivors present with good functional recovery and without severe disability in their everyday life.

Rheumatoid arthritis (RA) enhances the risk of cardiovascular disease to a similar extent as diabetes. Whereas atherogenesis remains poorly elucidated in RA, traditional and nontraditional risk factors associate similarly and additively with CVD in RA. Current recommendations on CVD risk stratification reportedly have important limitations. Further, reported data on CVD and its risk factors derive mostly from data obtained in the developed world. An earlier epidemiological health transition is intrinsic to persons living in rural areas and those undergoing urbanization. It is therefore conceivable that optimal CVD risk stratification differs amongst patients with RA from developing populations compared to those from developed populations. Herein, we briefly describe current CVD and its risk factor profiles in the African black population at large. Against this background, we review reported data on CVD risk and its potential stratification amongst African black compared to white patients with RA. Routinely assessed traditional and nontraditional CVD risk factors were consistently and independently related to atherosclerosis in African white but not black patients with RA. Circulating concentrations of novel CVD risk biomarkers including interleukin-6 and interleukin-5 adipokines were mostly similarly associated with both endothelial activation and atherosclerosis amongst African black and white RA patients.
