“…5 that the influence of rural-urban factors, urbanisation and adoption of western lifestyles particularly among relatively younger population plays an important role [4], [9], [11], [15], and [13]. Research evidence also found that younger patients have higher chance of surviving the acute phase of stroke with residual disability and much better outcomes than older patients leading to increased survivor rates [15].…”

“…Initial attempt to unravel the prevalence of stroke in a rural community of Niger Delta in 2014 reported a prevalence of 8.51/1000 [4]. This rate is about 6-fold higher compared to other regions in Nigeria and more than the rates found in most urban and rural populations in LMICs particularly in Africa and South America [7], [16], [17], [18], [19] and [20].…”

“…The stroke tool has also been used in previous studies in LMICs including Nigeria [4], [9], [11], [13] and [16]. In the last phase, participants adjudged to be positive cases in phase 2 were further invited in phase 3 to attend the neurological and laboratory examinations.…”

“…Evidence also found that the risk of death is higher in LMICs compared high income countries. The possible explanations for this observation have been due in part to direct effect of poverty, poor healthcare and increased comorbidity particularly HIV/AIDS [4]. Due to the current epidemiological transition driven by rapid economic development and combined effects of population growth and aging, and sociocultural changes, there is huge concern of continuous increase in the prevalence of stroke in LMICs including Nigeria, and among relatively younger populations [2].…”

“…Specifically, the prevalence of stroke across studies in Nigeria varies from 0·58/1000 in 1987 to 8.51/1000 in 2015 [4], [8], [9], [10], [11], [12] and [13]. Review evidence found that a 30-day case fatality and 3-year rate was as high as 40%, while the estimated mortality was 12.6/1000 persons [14].…”

The burden of stroke has been projected to increase in low-and middle-income countries due to the ongoing epidemiological transition. However, community-based stroke prevalence studies are sparse in sub-Saharan Africa particularly in Nigeria. This study aimed to provide a comparative estimate of the prevalence of stroke survivors in the rural Niger Delta region. A three-phased door-to-door survey was conducted using WHO modified instruments. In the first-phase, 2028 adults (≥18 years) participants randomly selected from two rural communities were screened by trained health research assistants for probable stroke. In the second phase, suspected cases were screened with stroke-specific tool. Positive cases were made to undergo complete neurological evaluation by two study neurologist in phase-three.Stroke diagnosis was based on clinical evaluation using WHO criteria. Overall, 27 (8 firstever and 19 recurrent cases) stroke survivors with crude prevalence of 13.31/1000 (95% CI, 8.32-18.31) and a non-significant difference in prevalence between the two study communities were found, (P= 0.393I). In addition, age-adjusted prevalence of stroke survivors was 14.6/1000 person, about 7-folds higher than previous estimates outside the Niger Delta region. The prevalence increases significantly with advancing in age, P<0·001.Among others, hypertension (92.59%) was the commonest risk factor and comorbidity found.Improved stroke surveillance and care, as well as better management of the underlying risk factors, primarily undetected or uncontrolled high blood pressure, remains a public health priority.
