Financial strain is associated with poorer sleep outcomes, with stronger associations among Asian individuals, particularly Pakistani individuals, compared to White individuals.

This longitudinal study of 36,544 individuals (114,164 person-years) from the UK Household Longitudinal Study found that financial strain was associated with poorer sleep quality, sleep disturbance, daytime dysfunction, sleep latency, and sleep medication use. The association was stronger among Asian individuals compared to White individuals, with the effect most pronounced in Pakistani individuals.

Stress disrupts sleep regulation pathways
↓
Racial-ethnic identity may amplify vulnerability to stress
↓
Result: Poorer sleep outcomes, especially in Pakistani individuals

Limitations

  • ⚠Abstract does not report specific effect sizes or confidence intervals
  • ⚠Subgroup analyses may have limited statistical power for smaller ethnic groups
  • ⚠Potential residual confounding from unmeasured variables (e.g., neighborhood factors, discrimination)
