Racial Differences in the Association Between Night Shift Work and Melatonin Levels Among Women

A total of 276 participants were analyzed, revealing statistically significant differences in melatonin levels between Asian and white night shift workers.

• Night shift work affected melatonin levels in both Asian and white participants.
• Asian night shift workers had 6-sulfatoxymelatonin levels closer to those of day shift workers compared to white night shift workers.
• Statistically significant differences in melatonin levels were observed between Asian and white night shift workers relative to day shift workers in every instance (P < 0.05).
• These findings suggest that Asians may have a better ability to maintain normal melatonin production patterns compared to whites.
