Age-Group and Gender Differences in Stroke Knowledge in an Israeli Jewish Adult Population

Ethnic and Gender Variations in Ischemic Stroke Patterns among Arab Populations in Northern Israel: A Preliminary Exploration towards Culturally Aware Personalized Stroke Care

The Galilee region of Israel boasts a rich ethnic diversity within its Arab population, encompassing distinct Muslim, Christian, Druze, and Bedouin communities. This preliminary exploratory study uniquely examined potential ethnic and gender differences in ischemic stroke characteristics across these Arab subgroups, which are seldom investigated separately in Israel and are typically studied as a homogeneous "Arab" sector, despite significant variations in their ethnicity, culture, customs, and genetics. The current study aimed to comparatively evaluate stroke characteristics, including recurrence rates, severity, and subtypes, within and across these distinct ethnic groups and between genders. When examining the differences in stroke characteristics between ethnic groups, notable findings emerged. The Bedouin population exhibited significantly higher rates of recurrent strokes than Muslims (M = 0.55, SD = 0.85 vs. M = 0.25, SD = 0.56; p < 0.05). Large vessel strokes were significantly more prevalent among Christians (30%) than Druze (9.9%; p < 0.05). Regarding gender differences within each ethnic group, several disparities were observed. Druze women were six times more likely to experience moderate to severe strokes than their male counterparts (p < 0.05). Interestingly, Druze women also exhibited a higher representation of cardio-embolic stroke (19.8%) compared with Druze men (4.6%; p < 0.001). These findings on the heterogeneity in stroke characteristics across Arab ethnic subgroups and by gender underscore the need to reconsider the approach that views all ethnic groups comprising the Arab sector in Israel as a homogeneous population; instead, they should be investigated as distinct communities with unique stroke profiles, requiring tailored culturally aware community-based prevention programs and personalized therapeutic models. The identified patterns may guide future research to develop refined, individualized, and preventive treatment approaches targeting the distinct risk factors, healthcare contexts, and prevention needs of these diverse Arab populations.

Al Meslamani A. Assessment of Knowledge and attitude towards Stroke among the UAE population during the COVID-19 pandemic: A cross-sectional study

Background: Despite significant advancements in healthcare, the burden of stroke continues to rise in the developed world, especially during the COVID-19 pandemic. Association between COVID-19 infection and stroke is well established. Factors identified for the delay in presentation and management include a lack of awareness regarding stroke. We aimed to assess the general public knowledge and attitudes on stroke and stroke risk factors in the United Arab Emirates during the COVID-19 pandemic. Methods: A cross-sectional study was conducted between September 2021 and January 2022 among adults≥ 18 years old. Participants completed a self-administered questionnaire on sociodemographic characteristics and stroke knowledge and attitudes. Knowledge and attitude scores were calculated based on the number of correct responses. Linear regression analysis was performed to determine the factors related to knowledge and attitude towards stroke. Results: Of the 500 respondents, 69.4% were females, 53.4% were aged between 18 and 25, and nearly half were students (48.4%). The mean knowledge score was 13.66 (range 2-24). Hypertension (69%), smoking (63.2%), stress (56.4%) obesity/overweight (54.4%), and heart disease (53.6%) were identified as risk factors. Overall, the knowledge of signs/symptoms was suboptimal. The mean attitude score was 4.41 (range, 1-6); 70.2% would call an ambulance if someone were having a stroke. A monthly income of 11,000-50,000 AED and being a student were associated with positive knowledge. Being a non-health worker and lacking access to electronic media sources were associated with worse attitudes. Conclusion: Overall, we identified poor knowledge and suboptimal attitudes toward stroke. These findings reflect the need for effective public health approaches to improve stroke awareness, knowledge, and attitudes for effective prevention in the community. Presently, this is of utmost necessity, given the increased occurrence of stroke and its severity among COVID-19 patients.

Variation in Knowledge of Stroke Warning Signs by Age and Presence of Conventional Risk Factors: A Community Health Survey in Korea

BACKGROUND

It is important to recognize stroke in the general public.

OBJECTIVES

The purpose of this study was to investigate factors affecting knowledge of stroke warning signs (SWSs) according to age group in the Korean population.

METHODS

This study is a cross-sectional study. Using data from the Korean Community Health Survey conducted in Korea in 2017, 198 403 subjects were analyzed. Knowledge about SWSs was assessed by face-to-face interviews using structured close-ended questionnaires with 5 items about stroke symptoms (sudden unilateral weakness of face, arm or leg; sudden difficulty in speaking, or trouble understanding speech; sudden visual impairment in 1 eye, or double vision; sudden dizziness or loss of balance; and sudden severe headache).

RESULTS

The overall percentage of subjects with good knowledge of SWSs (>4 correct answers to the SWS questionnaire) was 66.5%. It was highest in the middle-aged subjects (72.6%), followed by the young subjects (63.5%) and the older subjects (61.5%). The youngest of the young subjects and the oldest of the older subjects had the least knowledge. Subjects with conventional risk factors generally had more knowledge about SWSs, except for those with diabetes mellitus. However, in the young subjects, knowledge about SWSs was not increased by the presence of conventional risk factors such as hypertension and dyslipidemia.

CONCLUSION

Stoke risk factors are increasing among young people; they still have poor knowledge about SWSs. More education is needed to increase appropriate treatment, especially in young people with stroke-related risk factors.

Hypertension-Related Knowledge, Attitudes, and Behaviors among Community-Dwellers at Risk for High Blood Pressure in Shanghai, China

This study aimed to investigate the hypertension-related knowledge, attitudes, behaviors (KAB), and socio-demographic determinants among community-dwellers who were at risk for hypertension in Shanghai, China. A cross-sectional survey was conducted in a district of Shanghai in 2017 using multi-stage cluster sampling, including 611 participants who were at risk for hypertension. Questionnaires were used to investigate KAB regarding hypertension prevention. Multivariable logistic regression was performed to examine the relationship between socio-demographic factors and hypertension-related KAB. The results indicated that more than 75% of the study population had accurate knowledge, but only 48.4% knew the Recommended Daily Intake of salt for adults; over 80% formed health beliefs, while less than 50% were keeping a healthy diet, maintaining regular physical activity and/or bodyweight control. Better knowledge was found in the below 60 age group (p < 0.01) and the 60-69 age group (p = 0.03) than in the ≥70 age group. The behaviors in females (p < 0.01) were better than in males and were better in those covered by the Urban Employee Basic Medical Insurance (p = 0.01) than in those with the New Rural Cooperative Medical Insurance. In conclusion, although the rates of accurate knowledge and belief of hypertension prevention were high in the study population, the rates of maintaining healthy behaviors were relatively low. Socio-demographic factors had important influences on hypertension-related KAB. Further health education and intervention of hypertension prevention was needed to improve their level of KAB and reduce their risk for hypertension among the target groups.

Differences in knowledge of hypertension by age, gender, and blood pressure self-measurement among the Israeli adult population✰

BACKGROUND

Hypertension (HTN) is the most important risk factor for death and disability worldwide. Hypertensive patients' HTN knowledge was shown to be associated with control of HTN. Understanding factors affecting HTN knowledge might help control HTN.

OBJECTIVES

To examine differences in HTN knowledge by age, gender, ethnicity, years of education and whether HTN was diagnosed, and to explore whether HTN knowledge is affected by self-measurement of blood pressure (BP), in Israel's general population.

METHODS

A cross-sectional, descriptive, correlational design was used. A convenience sample of 430 Israeli adults, sampled in community centers across Israel, in four age groups (18-34, 35-49, 50-64, and above 64) were interviewed by 17 registered nurses, using a structured questionnaire with open-ended questions, during March 2017 and March 2018. ANOVA and chi-square tests for assessing differences between age groups in sociodemographic characteristics and BP measurement were used. Factors predicting knowledge of various HTN aspects and total HTN knowledge were explored by logistic and ordinal regression analyses.

RESULTS

Older participants, those with more years of education, and those who self-measured blood pressure had better knowledge of particular aspects of HTN and higher total HTN knowledge. Women had greater knowledge of normal systolic and diastolic BP.

CONCLUSIONS

Higher age, more years of education, and blood pressure self-measurement were associated with higher total HTN knowledge. The attention of health authorities should be drawn to improving HTN knowledge among younger adults, and to including blood pressure self-measurement in the regular practices of the general population.

Sex-Based Differences in Symptom Perception and Care-Seeking Behavior in Acute Stroke

CONTEXT

Lack of early stroke recognition and delays in seeking emergency care by persons experiencing a stroke severely limit acute treatment options. Sparse and sometimes conflicting evidence suggests sex differences in care-seeking behaviors in stroke, stroke knowledge, perceptions of stroke symptoms, and the importance of physical location at the time of stroke and of having a witnessed stroke.

OBJECTIVE

To explore specific sex-based differences in stroke presentation and associated care-seeking behaviors.

DESIGN

Descriptive study based on a convenience sample of 60 patients with stroke admitted to an academic medical center in Northern California.

MAIN OUTCOME MEASURES

Impact of the patient's sex on 1) time to presentation (early [≤ 4.5 hours] vs late [> 4.5 hours]); 2) perception of symptoms and clinical signs; 3) stroke knowledge and decision making; 4) physical location at the time of stroke; and 5) bystander presence and assistance with decision making.

RESULTS

There was a discrepancy between how patients perceive symptoms and their medical findings on physical examination. Although most patients had at least one sign or symptom associated with nationally used stroke recognition acronyms, both sexes delayed care because they did not perceive their symptoms as urgent. Early-presenting men were more likely to have a higher stroke severity score at admission, receive alteplase, arrive by Emergency Medical Services, and have a witnessed stroke. Both early- and late-presenting women reported more nonfocal symptoms than did men.

CONCLUSION

This study suggests that there are sex-based differences in symptom perception and care-seeking behavior in acute ischemic stroke.

Gender and thrombolysis therapy in stroke patients with incidence of dyslipidemia

BACKGROUND

When untreated, dyslipidemia is a higher risk factor for stroke and stroke-related mortality in men than in women. However, when dyslipidemia is treated the risk reduction is the same, but men benefited from mortality reduction more than women. Whether there is a gender difference in exclusion criteria for the use of recombinant tissue plasminogen activator (rtPA) or thrombolysis therapy in an acute ischemic stroke subpopulation with dyslipidemia is yet to be investigated.

METHOD

In a dyslipidemic stroke population obtained from a stroke registry, gender differences in exclusion risk factors were determined using clinical and demographic variables. Univariate analysis compared the recombinant tissue plasminogen activator (rtPA) group and the no rtPA group. Multiple regression analysis was used to determine demographic and clinical factors associated with inclusion and exclusion for rtPA in the total dyslipidemic stroke population and the subsets of the male and female population. The regression model was tested using the Hosmer-Lemeshow test, for the overall correct classification percentage. Significant interactions and multicollinearity between independent variables were examined using variance inflation factors.

RESULTS

A total of 769 patients presented with acute ischemic stroke with incidence dyslipidemia; 325 received rtPA while 444 were excluded from rtPA. Of those excluded from rtPA, 54.30% were female and 45.72% were male. In an adjusted analysis, female patients with increased age (OR = 1.024, 95% CI, 1.001-1.047, P < 0.05), with a history of carotid artery stenosis (OR = 7.063, 95% CI, 1.506-33.134, P < 0.05), and previous stroke (OR = 1.978, 95% CI, 1.136-3.442, P < 0.05) were more likely to be excluded from rtPA. Male patients with atrial fibrillation (OR = 2.053, 95% CI, 1.059-3.978, P = 0.033), carotid artery stenosis (OR = 2.400, 95% CI, 1.062-5.424, P = 0.035), and previous stroke (OR = 1.785, 95% CI, 1.063-2.998, P = 0.028) were more likely to be excluded from rtPA.

CONCLUSION

Although there are some similarities in the clinical risk factors for exclusion in both male and female stroke patients with incidence of dyslipidemia, there are differences as well. Elderly female stroke patients with incidence of dyslipidemia are more likely to be excluded from rtPA, even after adjustment for the effect of confounding variables. Further research should focus on how identified clinical risk factors can be targeted and managed to improve the use of rtPA in elderly female acute ischemic stroke population with incidence of dyslipidemia.
