Association of alternative healthy eating index with sleep quality among female students

The findings revealed no significant relationship between AHEI and sleep quality, both before and after adjusting for potential confounding variables (P = 0.781, P = 0.454). However, specific components of the AHEI, particularly fruit and polyunsaturated fatty acids (PUFAs), showed significant associations with sleep quality. Higher fruit intake was linked to better sleep quality (OR = 0.856, P = 0.013), while surprisingly, increased PUFA consumption was associated with poorer sleep quality (OR = 1.377, P = 0.007). These results suggest that while AHEI did not correlate with sleep quality, individual dietary components, particularly fruit and PUFAs, might be associated with sleep quality.
