Female Patients

Optimal stroke prevention strategies for women should take into account specific sex-related stroke risk factors. Anemia is a common medical condition in females, particularly in women of reproductive age. This study investigated whether anemia is an independent risk factor for stroke in females in a population-based cohort study. We investigated newly diagnosed anemic female patients with no history of central nervous system disease, psychiatric disorders, traumatic brain injury, major operations or hemorrhagic diseases identified from the Taiwan National Health Insurance Research Database. Non-anemic matched controls (1:1) were selected based on a propensity score estimated using a logistic regression model that included demographic characteristics and comorbidities. A competing risk analysis was applied to estimate the stroke risk in anemic patients compared to that of their matched controls. In our study, the adjusted sub-distribution hazard ratios (aSHRs) of overall, hemorrhagic and ischemic stroke in anemic female patients aged <50 years were 1.35 (95% confidence interval (CI): 1.19–1.52, p < 0.001), 1.31 (95% CI, 1.09-1.56, p < 0.003), and 1.35 (95% CI, 1.15–1.58, p < 0.001), respectively, compared to non-anemic female controls. However, a positive association between anemia and stroke was not found for those aged ≥50 years. Similar results were observed when the follow-up age was limited to 50 years to reduce the potential effects of menopause on stroke. In conclusion, the present population-based cohort study found that anemia is a potential risk factor for overall, hemorrhagic and ischemic stroke in females of reproductive age.

Background Headache has not been established as a risk factor for dementia. The aim of this study was to determine whether any headache was associated with subsequent development of vascular dementia (VaD), Alzheimer’s disease (AD) or other types of dementia. Methods This prospective population-based cohort study used baseline data from the Nord-Trøndelag Health Study (HUNT 2) performed during 1995–1997 and, from the same Norwegian county, a register of cases diagnosed with dementia during 1997–2010. Participants aged ≥20 years who responded to headache questions in HUNT 2 were categorized (headache free; with any headache; with migraine; with nonmigrainous headache). Hazard ratios (HRs) for later inclusion in the dementia register were estimated using Cox regression analysis. Results Of 51,383 participants providing headache data in HUNT 2, 378 appeared in the dementia register during the follow-up period. Compared to those who were headache free, participants with any headache had increased risk of VaD ( n = 63) (multivariate-adjusted HR = 2.3, 95% CI 1.4–3.8, p = 0.002) and of mixed dementia (VaD and AD ( n = 52)) (adjusted HR = 2.0, 95% CI 1.1–3.5, p = 0.018). There was no association between any headache and later development of AD ( n = 180). Conclusion In this prospective population-based cohort study, any headache was a risk factor for development of VaD.
