Stroke: Women vs. Differences in men's risk of stroke and transient ischemic episodes depend on age

Women have a lower overall risk of stroke or transient ischemic (TIA) episodes than men.
, women were observed to have a lower risk in the 40-80 age group.
in people under 30, the risk of stroke/TIA is higher for women than for men, while for people over 80, there is no gender difference in stroke/TIA risk.
, according to the Global Burden of Disease Study, the incidence of stroke in women is lower than in men (1.54 vs. 1.59/1000), but the risk of stroke is higher throughout life.
previous studies have documented gender differences in stroke rates, however, little is known about stroke rates by sex and age in adulthood.
In a recent study published in the authoritative journalStroke, Dr. Manav V. Vyas of the Institute of Neurology and Health Policy, Management and Evaluation, Department of Neurology and Health Policy, Management and Evaluation, University of Toronto, et al., used administrative health data from Ontario, Canada, to study the relationship between gender and stroke (ischemic stroke, intracranial bleeding, or subcranial hemorrhage) or TIA seizures during adulthood.
previous registration-based studies have shown that women aged 45 have a higher risk of stroke than men, and women aged 75 have a similar risk of stroke.
these observations may be attributed to changes in the prevalence of stroke risk factors, including gender-specific factors such as hormonal changes during pregnancy and throughout life.
this, the researchers hypothesically assumed that women's risk of stroke was generally lower than men's, but that risk differences varied between age groups, further assessing the effect of age on the relationship between gender and the incidence of stroke or TIA seizures.
in the team study, researchers analyzed 9.2 million adults (51 percent female) who were 18 years of age and older with no history of stroke or TIA seizures to assess the relationship between gender and the incidence of stroke in adulthood.
1. The relationship between gender and stroke of 9.2 million residents of Ontario, Canada, from 1 January 2003 to 31 March 2018. The relationship between incidence and sex of stroke type in different age groups was between 280,197 adults who had stroke or TIA seizures during the 15-year mean follow-up period; .81-0.82), except for the higher risk of subcity bleeding in women (HR=1.29; 95% CI 1.24-1.33), all stroke types were consistent.
Figure 3. The U-type association between gender differences and the incidence of stroke or transient cerebral ischemic seizures (TIA) was found in age analysis, with women under 30 at higher risk of stroke or TIA seizures than men (HR=1.26; 95% CI 1.1-1.45); The risk of TIA seizures is lower than in men (HR=0.69; 95% CI 0.68-0.7), and in people aged 80 or over, the risk of stroke or TIA seizures is similar in women and men (HR=0.99; 95% CI 0.98-1.01).
results show that there are significant differences in stroke rates between women and men throughout the life cycle, and that the effects of gender on stroke rates are U-shaped throughout the adult life cycle: young women are at higher risk than younger men, middle-aged women are at lower risk than middle-aged men, and older women are at higher risk than older men.
age-gender differences in understanding the incidence of stroke can help guide prevention efforts to reduce the incidence of stroke in both men and women.
