This study found a 15.3% insomnia prevalence in Singaporean Malays and Chinese, with females and Malays at higher risk. Insomnia was linked to stress, psychiatric issues, and poor sleep quality, yet most patients did not seek medical help.

Area of Science:

  • Sleep Medicine
  • Public Health
  • Epidemiology

Background:

  • Insomnia is a common sleep disorder with significant public health implications.
  • Limited data exists on insomnia prevalence within specific ethnic groups in Singapore.
  • Understanding ethnic-specific risk factors is crucial for targeted interventions.

Purpose of the Study:

  • To determine the prevalence of insomnia among the Malay and Chinese populations in a Singaporean community.
  • To identify demographic and clinical factors associated with insomnia in these groups.
  • To explore healthcare-seeking behaviors related to insomnia.

Main Methods:

  • Community-based cross-sectional study.
  • Inclusion of Malay and Chinese adult participants residing in Singapore.

  • Assessment of insomnia symptoms, sleep quality, stress levels, and psychiatric comorbidities.

    • Main Results:

    • Overall insomnia prevalence was 15.3%.
    • Females and individuals of Malay ethnicity demonstrated a higher risk of insomnia.
    • Insomnia patients reported increased sleep latency, nocturnal awakenings, daytime fatigue, higher stress levels (particularly domestic), and a greater likelihood of minor psychiatric disorders.

    Conclusions:

    • Insomnia affects a notable proportion of the Malay and Chinese communities in Singapore, with specific demographic at-risk groups identified.
    • The study highlights the association between insomnia, stress, and mental health comorbidities.
    • A significant gap exists in medical help-seeking behavior for insomnia, with low utilization of sleeping pills.
