Risk factor assessment of stroke and its awareness among stroke survivors: A prospective study

The Distribution of Lifestyle Risk Factors Among Patients with Stroke in the Indian Setting: Systematic Review and Meta-Analysis

Background

The burden of stroke is increasing in India, but there is limited understanding of the distribution of reported risk factors in the Indian setting. It is vital to generate robust data on these modifiable risk factors to scale up appropriate strategies for the prevention of cerebrovascular diseases in this setting.

Summary

The objective of this study is to estimate the overall proportion of life style risk factors of patients with stroke in the Indian setting. We searched PubMed and Google Scholar and relevant studies published till February 2022 were included. The risk of bias assessment was considered for the study selection criterion in the meta-analysis. The publication bias was evaluated by funnel plots and Egger's test. We identified 61 studies in the systematic review and after quality assessment, 36 studies were included for meta-analysis. Random effect model was used due to the significant inconsistency among the included studies (I2 > 97%). The mean age of the participants was 53.84±9.3 years and patients with stroke were predominantly males (64%). Hypertension (56.69%; 95% CI: - 48.45 - 64.58), obesity (36.61%; 95% CI: - 19.31 - 58.23), dyslipidemia (30.6%; 95% CI: - 22 - 40.81) and diabetes mellitus (23.8%; 95% CI: - 18.79 - 29.83) are the leading intermediate conditions associated with stroke. The Physical inactivity - 29.9% (95% CI: - 22.9 - 37.1), history of tobacco use (28.59 %; 95% CI: - 22.22 - 32.94) and alcohol use (28.15 %; 95% CI: - 20.49 - 37.33) were reported as the behavioral risk factors for stroke in this setting.

Key Messages

The current meta-analysis provides robust estimates of the life style related risk-factor of stroke in India based on the observational studies conducted from 1994 to 2019. Estimating the pooled analysis of stroke risk factors is crucial to predict the imposed burden of the illness and ascertain the treatment and prevention strategies for controlling the modifiable risk factors in this setting.

Level of Knowledge on Stroke and Associated Factors: A Cross-Sectional Study at Primary Health Care Centers in Morocco

Background:

Stroke is increasingly becoming a major cause of disability and mortality. However, it can be prevented by raising awareness about risk factors and early health care management of patients.

Objective:

The aim of this study is to assess the level of knowledge on stroke, its risk factors, and warning signs in the population attending urban primary health care centers in the city of Agadir, Morocco.

Methods:

This is a multicentric cross-sectional study with a descriptive and analytical purpose. The study was conducted at five urban primary health care centers in Agadir in centralwest Morocco. All persons over the age of 18 years who consulted the health centers and who agreed to fill in the questionnaire were recruited, except for the foreign population and health workers. An interview questionnaire was used to assess the level of knowledge on stroke.

Findings:

A total of 469 participants were involved in the study. The median knowledge score was 8 (Interquartile range 4–13). High blood pressure (55.7%), depression and stress (48.8%) were the most well-known risk factors. Sudden weakness of the face, arms or legs (37.3%) was the main warning sign cited by the participants. Multivariate analysis revealed that illiteracy (OR 1.92; CI_95%: 1.08–3.44) primary education (OR 3.43; CI_95%: 1.63–7.21), rural residential (OR 1.67; CI_95%: 1.07–2.59), no history of stroke among respondents (OR 16.41; CI_95%: 4.37–61.59) and no history of stroke among relatives, acquaintances, or neighbors (OR 4.42; CI_95%: 2.81–6.96), were independently associated with a lower level of knowledge of stroke (Table 4).

Conclusions:

The low level of knowledge on stroke among this Moroccan population indicates the importance of implementing stroke education initiatives in the community. More specifically, proximity education and awareness programs ought to be considered to anchor lifestyle preventive behaviors along with appropriate and urgent actions regarding the warning signs of stroke.

Awareness of Stroke and Health-seeking Practices among Hypertensive Patients in a Tertiary Care Hospital: A Cross-sectional Survey

Introduction: Stroke is a major cause of death with hypertension being identified as an important modifiable risk factor. Prompt identification of stroke symptoms and timely management is noted to be significant in lowering both morbidity and mortality. Baseline stroke knowledge in hypertensive patients is crucial to develop effectively targeted, and appropriate health promotion campaigns; thus, the main objectives of this study are to assess the awareness of stroke and to determine health-seeking practices among hypertensive patients.

Materials and methods: A standardized questionnaire survey regarding awareness and practices about stroke among hypertensive patients was conducted in a tertiary care hospital of Islamabad. The sample size was calculated as 384.

Results: Out of 384 patients evaluated, 80.5% had heard about stroke, 71.6% knew someone with stroke, and 76% identified the brain as the organ affected. Sudden onset numbness of limb (66.9%) and hypertension (93.5%) were common warning symptom and risk factor identified. 87.5% would take stroke patients to a hospital. Only 45.1% of the patients took their medications regularly, and 38% checked their blood pressure.

Conclusion: Majority of hypertensive patients were aware of stroke but the awareness of risk factors and warning signs was poor. Stroke prevention practices were also sub-optimal. There is a need to increase knowledge regarding risk factors, which will benefit the community at large.

A retrospective analysis of time delays in patients presenting with stroke to an academic emergency department

Background

Stroke presents commonly to the emergency department (ED), and is a common cause of morbidity and mortality in South Africa. Early ED presentation and early neuroimaging are required in order for thrombolysis to be a potential therapeutic modality.

Objectives

To determine the time to ED presentation, time to computed tomography (CT) scan and the potential influencing factors for patients with stroke.

Methods

A retrospective record review of all patients who presented with clinical features of stroke to a tertiary academic ED in Johannesburg, South Africa, from 01 January to 31 December 2014.

Results

Data from 232 eligible stroke patients were analysed. The median time to presentation to the ED was 33 h with the majority of patients (81.3%) presenting after the 4.5 h window for thrombolysis. The median time to CT was 8 h. Only 3.9% of patients had a CT scan within one hour of arrival. Patients with loss of consciousness were associated with earlier hospital presentation (p = 0.001). None of the patients were thrombolysed.

Conclusion

Patients with stroke commonly present late to hospital. If we are to make a difference in this group of vulnerable patients, further education and training needs to be emphasised regarding ‘time is brain’. Communication and commitment is also required by the emergency medical services, ED and radiology staff in order to prioritise stroke patients and to reduce delays.

Knowledge of Stroke Risk Factors among Stroke Survivors in Nigeria

Background. Knowledge of stroke risk factors is expected to reduce the incidence of stroke—whether first-ever or recurrent. This study examined knowledge of stroke risk factors and its determinants among stroke survivors. Methods. A cross-sectional survey of consenting stroke survivors at two physiotherapy facilities in Nigeria was carried out. Sociodemographic and clinical data were obtained and knowledge of stroke risk factors (defined as the ability to mention at least one correct risk factor) was assessed using open-ended questionnaire. Data were treated with descriptive statistics and logistic regression analysis. Results. Sixty-nine stroke survivors (male = 72.5%; mean ± SD age = 49.7 ± 10.6 years) participated in the study. Thirty-four (49.4%) participants had knowledge of stroke risk factors. Only educational level was significantly associated with knowledge and participants with tertiary educational qualification were about 48 times (odds ratio = 48.5; CI = 7.6–309.8; P < 0.0001) more likely to be knowledgeable than those with no education. Conclusion. Less than half of the participants had knowledge of stroke risk factors. Participants with tertiary education were significantly more knowledgeable than those with lower educational qualifications. Effective means of educating stroke survivors on stroke risk factors should be identified and adopted.
