MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Although sleep duration has been related to a number of negative health outcomes, few studies have examined the relationship between place of birth and sleep duration. We examined data for 416,152 adult participants living in the United States between 2000-2013 who responded to the National Health Interview Survey (NHIS); associations were explored between healthy sleep duration (7-8hrs.), references to unhealthy sleep duration (8 hrs.) and place of birth.
After adjusting for socio-demographic factors, health risks, and physician-diagnosed medical conditions, multivariate logistic regression revealed that respondents born in the Indian subcontinent were more likely to report healthy sleep duration, compared with US-born respondents (OR=1.86, 95% CI: 1.57-2.20, p < 0.001), while individuals born on the continent of Africa were least likely to report healthy sleep duration (OR= 0. 86, 95% CI: 0.73-1.02, p< 0.001). We also noted a trend suggesting that the longer immigrants reside in the U.S., the greater their likelihood to experience unhealthy sleep.
