Hypothesis

What is the true prevalence of asthma by gender and age groups in the population of the area covered by one urban Health Centre in Portugal?

Conclusion

The prevalence of asthma in the studied population was found to be 10.24%, which is higher than some previous studies but lower than others.

Supporting Evidence

  • The study found a 10.24% prevalence of asthma in the sampled population.
  • Data were collected from 576 patients, achieving a 97.6% response rate.
  • The mean age of asthma patients was 27.0 years, which was lower than non-asthmatics.

Takeaway

In a study of people in Matosinhos, Portugal, about 1 in 10 had asthma, which is more than some earlier studies showed.

Methodology

An observational study with a random sample of 590 patients, using questionnaires to collect data on respiratory symptoms and asthma status.

Potential Biases

Potential biases may arise from self-reported symptoms and the reliance on physician diagnosis.

Limitations

The study's findings may not be generalizable to other regions of Portugal due to regional differences.

Participant Demographics

The mean age of participants was 33.2 years, with 51.6% being female.
