Point process models in asthma attacks for assessing environmental risk factors.

T Kamakura, T Yanagimoto

    Environmental Health Perspectives
    |November 1, 1985
    PubMed
    Summary

    Point process models effectively analyze environmental risk factors impacting asthma attacks. Logit and proportional intensity models are key for diary data, revealing influential covariates.

    Area of Science:

    • Environmental epidemiology
    • Biostatistics
    • Asthma research

    Background:

    • Asthma attacks are influenced by environmental factors.
    • Accurate modeling is crucial for understanding asthma triggers.
    • Longitudinal data collection is common in asthma studies.

    Purpose of the Study:

    • To review and discuss point process models for asthma attack analysis.
    • To identify effective models for analyzing longitudinal asthma diary data.
    • To explore covariates influencing asthma exacerbations.

    Main Methods:

    • Review of point process models.
    • Application of logit and proportional intensity models.
    • Analysis of longitudinal asthma diary data.
    • Exploration of covariates using statistical models.

    Main Results:

    • Point process models are suitable for analyzing asthma attack data.
    • Logit and proportional intensity models are effective for diary data.
    • Identified covariates influencing asthma exacerbations.

    Conclusions:

    • Point process models provide a robust framework for asthma research.
    • Logit and proportional intensity models are valuable tools for analyzing asthma triggers.
    • Further research can focus on smoothed baseline intensity estimation using Bayesian models.
