Area of Science:

  • Sleep Medicine
  • Public Health
  • Sociology

Background:

  • Insomnia is a prevalent sleep disorder with significant health consequences.
  • Socioeconomic status (SES) is a known determinant of health outcomes.
  • The relationship between SES and insomnia requires further investigation.

Purpose of the Study:

  • To compare the prevalence of insomnia and related health issues across different socioeconomic statuses.
  • To examine the impact of individual, household, and community education levels on insomnia.
  • To assess the subjective impairment caused by insomnia in relation to education.

Main Methods:

  • Recruitment of participants aged 20-80+ using random-digit dialing.
  • Collection of data through 2-week sleep diaries and questionnaires on fatigue, sleepiness, and distress.

  • Measurement of socioeconomic status via individual, household, and community education levels.

    • Main Results:

    • Lower individual and household education levels were significantly associated with a higher likelihood of insomnia, even after controlling for demographic factors.
    • Individuals with fewer years of education, especially high school dropouts, reported greater subjective impairment due to insomnia.
    • Education level emerged as a key factor influencing both the occurrence and impact of insomnia.

    Conclusions:

    • Socioeconomic disparities, particularly in education, contribute to unequal sleep health.
    • Public health initiatives should address educational inequalities to mitigate insomnia prevalence and its consequences.
    • Targeted interventions for individuals with lower educational attainment may improve insomnia management and reduce associated health burdens.
