Nutritional biomarkers and factors correlated with poor sleep status among young females: A case-control study
In this study by Al-Musharaf et al. (2022), the authors explored the factors and nutritional biomarkers implicit in sleep quality in a population of 92 young females (ages 19 to 25, normal weight to obese). Participants’ insulin resistance was evaluated using the homeostasis model assessment of insulin resistance (HOMA-IR), in addition to recording data on lipid profiles, fasting blood glucose, stress, anthropometric measurements, dietary intake (especially polyphenol content), and physical activity level. Finally, sleep was evaluated via the Pittsburgh sleep quality index (PSQI). Analysis of the results showed that high insulin resistance was associated with poor sleep (HOMA-IR) and that dietary phenol intake protected the participants from suffering from poor sleep quality. On the other hand, factors like BMI, vitamin intake, lipid profile, and investigated nutritional biomarkers had a relatively non-substantial association with sleep quality. The authors conclude that low dietary polyphenol intake and higher levels of insulin resistance are linked to poor sleep status in reproductive-age females.
