Hypothesis

What is the prevalence of stroke among elderly populations in Spain compared to other European countries?

Conclusion

Stroke prevalence in central and north-eastern Spain is higher in males and in suburban areas, with significant geographic variation.

Supporting Evidence

  • Age-adjusted prevalences were 7.3% for men and 5.6% for women.
  • Prevalence was significantly lower in women, with an odds ratio of 0.79.
  • Prevalences were highest in suburban areas at 8.7% and lowest in rural areas at 3.8%.
  • Statistically significant differences were found when comparing Spanish populations to Italian populations.

Takeaway

This study found that more older men in Spain have strokes, especially in suburban areas, and that the number of strokes varies a lot depending on where you live.

Methodology

The study analyzed screening surveys targeting stroke prevalence in Spanish populations aged 70 and over, using logistic regression for data analysis.

Potential Biases

Potential publication bias was addressed by including unpublished studies, but only reported studies were used for European comparisons.

Limitations

The study may have limitations due to methodological differences in the surveys and the exclusion of unpublished studies from European comparisons.

Participant Demographics

The study included 10,647 participants, with 41% men and 59% women, aged 70 and over.
